Terms of Service

• Effective date: October 27, 2026
• Last updated: October 27, 2026
• Applies to: grindlabs.ca, lagrind.ca, grindclinic.ca, grindmarket.ca, the Grind Labs web and progressive web applications, the Grind Labs apps for iPhone, iPad, Android and Windows, Grind Clinic, Grind Market, CBSE Grind and other Grind Labs or La Grind products, and related digital services that link to these Terms (collectively, the “Service”).

Language. The French version remains available at all times. Before a Quebec user enters an adhesion contract in English, the French version must be provided and the user must expressly choose English. Both versions are intended to grant the same substantive rights and obligations; neither version is declared universally controlling.

Key points

• Grind Labs is an educational study service, not professional advice or a substitute for an instructor, regulator, clinician, or emergency service.
• We do not guarantee any score, admission, licence, ranking, employment, or other outcome. The only exception is a guarantee written on a product's page and at checkout, on the conditions given at purchase.
• Your account is personal. Protect it, provide accurate information, and use only content you are authorized to use.
• You must be at least 16 to have an account. Under 18, you need a parent's or guardian's agreement to buy anything.
• You retain ownership of content you create. You give us the limited rights needed to operate the features you choose and show content to the audience you select.
• Community, messaging, calling, file, and AI features carry privacy, copyright, accuracy, and conduct responsibilities. Outside Grind Clinic's patient list, do not submit patient-identifying material, and never submit exam-confidential, pirated, or unlawfully obtained material.
• We do not tolerate objectionable content or abusive users. Report them in the app or at hello@grindlabs.ca, and we act promptly.
• Grind Clinic is only a tool to plan your clinic week and remind patients of their visits from your own phone. It is not a patient record: enter no health information beyond the few words a reminder needs. You must follow your school clinic's privacy rules and have each patient's agreement; see section 5.
• Grind Market lets creators share study resources. Creators keep ownership and must have the right to share what they post; what you add is for your own study.
• Purchases happen only on our website and are processed by Stripe; our apps for iPhone, iPad, Android and Windows sell nothing. Any renewal, trial, cancellation, refund, tax, and delivery terms shown at checkout are part of your purchase.
• The direct-purchase refund promise in section 8 and all mandatory consumer rights remain available. Grindstones (stones) are Service credits, not money or an investment. You may give stones you bought to a friend in the app, and stones you buy never expire while your account is open.
• The Service changes and can fail. Keep copies of irreplaceable work and verify educational or AI-generated content before relying on it.

This summary is for convenience. The complete Terms below govern your use of the Service.

1. Agreement, Service, and language

The Service is provided by Grind Labs Inc., a Canadian corporation based in Quebec, Canada (“Grind Labs,” “we,” “us,” or “our”). Grind Labs is our English-facing brand and La Grind is our French-facing brand. CBSE Grind is one study product, not the company. Contact us at hello@grindlabs.ca, at 514-928-7434, or by mail at 71 rue Papillon, Dollard-des-Ormeaux, Quebec H9B 3J7, Canada.

These Terms apply to our websites, progressive web application, apps for iPhone, iPad, Android and Windows, Grind Clinic, Grind Market, study and assessment products, community and collaboration features, AI tools, digital coaching surfaces, purchases, and related support services that link to them. The Privacy Policy explains our handling of personal information.

By creating an account, selecting an acceptance control, buying or redeeming access, or using the Service after these Terms are presented, you agree to them. If you use or purchase the Service for an organization, you represent that you have authority to bind it. Additional terms shown for a particular product, promotion, institution, beta, or purchase form part of these Terms; the more specific term governs that feature or transaction if there is a conflict.

For a Quebec adhesion contract, we provide the French version before asking a user to expressly choose English. A language choice does not waive rights under the Charter of the French language or other mandatory law. Both versions remain available at grindlabs.ca/terms and lagrind.ca/terms.

2. Eligibility and accounts

You must be at least 16 years old to create an account. If you are under the age of majority where you live (18 in Quebec), you may buy a plan, stones or another paid item only with the agreement of a parent or guardian, and by buying you confirm that you have it. The Service is not directed to children; if we learn that an account belongs to someone under 16, we close it and delete its information.

You must provide accurate, current information; use an email address you control; keep passwords, recovery codes, and authentication devices confidential; use available security features; and tell us promptly at hello@grindlabs.ca if you suspect unauthorized access. You are responsible for activity carried out through your credentials unless applicable law provides otherwise.

An individual account is for one person and may not be shared, rented, sold, transferred, or used to bypass access limits. Organizational, staff, cohort, school, coaching, and testing roles may require verification and may be limited or removed when the role or entitlement ends. You may not impersonate another person or misstate your school, role, age, qualifications, or authority.

3. Educational purpose and no professional advice

The Service is an educational aid. It is not medical, legal, financial, clinical, admissions, or other professional advice, and it is not diagnosis, treatment, supervision, accreditation, or an official exam. Never use it to make decisions about a real patient, client, emergency, or other situation where professional judgment is required. Contact a qualified professional or emergency service when appropriate.

Grind Clinic is only a scheduling and reminder tool for students: it helps you plan your week and remind patients of their visits, and nothing more. It is not a patient record or a medical device, and it does not diagnose, treat, or give clinical advice; your clinic's instructors and record system remain the authority for patient care.

There is no guarantee of any score, admission, licensure, certification, ranking, employment, clinical performance, or other outcome. The only exception is a guarantee that a product's page and checkout state in writing, such as a money-back guarantee; it applies only on the eligibility and claim conditions given at purchase, and it never guarantees admission. Practice scores, projections, feedback, analytics, sample answers, and AI output are estimates or learning aids. You remain responsible for checking current official standards and making your own decisions.

Grind Labs is independent. Unless we expressly say otherwise in writing, the Service is not affiliated with, sponsored by, approved by, or endorsed by the NBME, USMLE program, FSMB, MCC, CaRMS, Altus, Acuity Insights, any examination owner, regulator, university, school, hospital, professional order, or employer. Their names and marks belong to their respective owners and are used only to identify the examinations or services discussed.

4. Licence and intellectual property

Subject to these Terms and your applicable entitlement, Grind Labs grants you a limited, revocable, personal, non-exclusive, non-transferable, and non-sublicensable licence to access the Service for your own lawful education. No ownership in the Service or our content transfers to you.

Our software, interfaces, designs, brands, questions, explanations, simulations, grading methods, study programs, library material, graphics, audio, video, and other original content are owned by or licensed to Grind Labs and protected by intellectual-property law. Third-party material remains the property of its owner.

Except where applicable law expressly permits it despite these restrictions, you may not:

• copy, screen-capture in bulk, scrape, crawl, index, mirror, archive, download, extract, or reconstruct substantial Service content;
• publish, share, sell, sublicense, rent, lend, redistribute, or build a competing dataset or product from the Service;
• provide Service content, outputs, or access to train, evaluate, ground, or improve another machine-learning model without our written permission;
• share credentials, evade limits, falsify entitlements, remove rights notices, or bypass security, rate, payment, moderation, or access controls;
• reverse engineer, decompile, probe, attack, disrupt, introduce malware to, or make unauthorized automated use of the Service; or
• use our names, marks, visual identity, or confusingly similar branding without written permission.

If you voluntarily send feedback, you allow us to use it without restriction or compensation, but this does not transfer ownership of your separate user content.

5. Your content and uploads

“User Content” means notes, messages, posts, profile information, answers, decks, questions, files, recordings made outside the Service, feedback, and other material you submit or create. You retain the ownership rights you have in your User Content.

You grant Grind Labs a worldwide, non-exclusive, royalty-free licence to host, store, process, reproduce, transmit, and display User Content only as reasonably needed to operate, secure, support, improve, and comply with law for the feature you chose and the audience you selected. This licence ends when the content is deleted from active systems, except for recipient copies, backups, legal holds, moderation evidence, and other retention described in the Privacy Policy. Public feedback or submissions specifically provided for publication may remain available as disclosed when submitted.

You represent that you have the rights, permissions, confidentiality authority, and valid consents needed for your User Content and our permitted processing. You are responsible for its legality and accuracy and for choosing the correct audience. Do not submit:

• patient-identifying or identifiable patient information, protected health information, or real clinical records, except the scheduling details Grind Clinic asks for, as described below;
• stolen exam content, recalled live questions, exam-confidential material, answer keys obtained through misconduct, or material that facilitates cheating;
• pirated books, unauthorized course files, copyrighted material you lack permission to use, trade secrets, or another person's confidential information;
• malware, credentials, financial-account secrets, unlawful surveillance material, intimate content shared without consent, or content that violates privacy or publicity rights; or
• content that is illegal, fraudulent, defamatory, threatening, exploitative, or designed to harm the Service or another person.

Grind Clinic. Grind Clinic lets you keep, on your own device, a patient's first name or initials, phone number and visits, a few words on a planned visit when its reminder needs them, and short notes for yourself, to book clinic visits and send reminders. Enter only what that needs. Never enter any other health information, such as a medical history, diagnoses, medications, X-rays or clinical records, or health card or file numbers. You must follow your school clinic's privacy and communication rules, have each patient's agreement before texting them, and remove their details when you no longer need them. You send each reminder yourself, from your own phone; we do not text or call patients. If you share a message you wrote with friends or with everyone, it must not contain any patient's details; a message shared with everyone reaches other students only after we review it. The Privacy Policy explains where this information is kept and how it is deleted.

Grind Market. Grind Market (grindmarket.ca) lets creators publish study resources that other users add to their Grind Labs library. If you publish a resource, you keep ownership of it, you confirm that you made it or have the right to share it, and you give us the licence above to show it on the Market and deliver it to the people who add it. Each resource is reviewed before it becomes public; we may refuse or remove it and act on reports. A resource you add from the Market is licensed to you for your own study only; you may not copy, share, resell or export it except as the Market allows. Paid resources, rentals and payouts to creators open only once we publish the seller terms that govern them; the price, access period and renewal shown at checkout then apply. Resources that Grind Labs publishes on the Market are our content under section 4.

We may remove or restrict content when we reasonably believe it violates these Terms, law, another person's rights, or Service safety. Copyright and other rights notices may be sent to hello@grindlabs.ca with the work, disputed material, location, contact information, authority, and good-faith basis for the request. We may request more information and may restrict repeat infringers.

6. Community, messaging, cohorts, and calls

Profiles, directories, cohorts, groups, shared study items, shared Grind Clinic messages, Market reviews, gifts of stones, community posts, direct messages, reports, presence indicators, and calls allow interaction with other users. User Content is supplied by users, not endorsed or verified by Grind Labs. Privacy settings and audience labels reduce visibility but cannot guarantee secrecy or retract copies a recipient lawfully received, exported, photographed, or recorded outside our tools.

You must not harass, threaten, stalk, discriminate, sexually exploit, dox, defraud, spam, impersonate, manipulate, or intimidate anyone; encourage self-harm or violence; evade blocks or moderation; solicit credentials; distribute malicious or unlawful material; disrupt a group or class; or use the Service to cheat or coordinate exam misconduct.

We do not tolerate objectionable content or abusive users. Use the reporting and blocking tools or contact us when content or conduct violates these Terms. Reports inform moderation and may be reviewed with associated content. We review reports promptly and remove content that violates these Terms, and we suspend or close the accounts responsible when the conduct is serious or repeated. We may preserve evidence, limit visibility, remove content, restrict features, or suspend accounts. Reporting does not guarantee a particular result. Knowingly false or abusive reports may themselves violate these Terms.

Calling is a communication feature, not an emergency service. You must obtain appropriate consent before enabling camera or microphone. The Calling feature does not record calls, but another participant or outside software may be capable of recording. You are responsible for notices and consent required by the laws where participants are located. Do not use calls for emergencies, regulated telehealth, confidential patient discussions, or any purpose that requires guaranteed availability, identity, recording, or security controls the feature does not provide.

Casper coaching. When your plan includes coaching or a review, the coaches assigned to your take see and hear it, with its transcript, and may write to you or meet with you by call. Coaches must keep what they see confidential and use it only to coach you. Feedback and scores are an opinion meant to help you practise: they are not official Casper results, have no connection to Acuity Insights, and guarantee no result except under a written guarantee described in section 3. Sessions follow the booking, rescheduling and cancellation rules shown when you book.

7. AI features

When you choose an AI feature, your prompt, selected Service context, extracted upload text, selected page images, instructions, and related technical information may be sent to an AI service provider to generate a response. The Privacy Policy names each current provider and explains the data flow. When you use a Bring your own AI step, you copy our prompt into an AI service you choose; that service's terms govern what you send it, and we do not see that conversation.

AI output may be wrong, inaccurate, incomplete, outdated, biased, unsafe, or similar to material supplied to other users. Verify important information against reliable sources. Do not use output for patient care, emergencies, professional decisions, official assessment, or misconduct. You are responsible for how you use, edit, disclose, or submit it.

Do not provide patient information, biometric identifiers, exam-confidential content, trade secrets, credentials, highly sensitive personal information, or third-party proprietary material to AI features unless the feature expressly permits it and you have lawful authority and informed consent. We do not promise that an output is unique, owned exclusively by you, fit for a purpose, accurate, or non-infringing. Your rights in output, if any, are subject to applicable law, these Terms, and rights in underlying material.

A feature that uses stones shows how many it will use before it runs. When the product requires confirmation, the number shown and the feature rules control the debit. We may correct or restore a debit caused by a verified technical failure, duplicate charge, or non-delivery; we do not promise a refund merely because an output was not useful or preferred.

8. Plans, purchases, subscriptions, and Grindstones

The product page and checkout shown before acceptance identify the item or service, price, currency, applicable taxes and fees, access term, delivery timing, renewal status, cancellation method, restrictions, and included features. Those transaction disclosures, the purchase confirmation, and any more favourable written offer form part of your contract. Prices may vary by region, platform, promotion, or tax treatment.

Purchases happen only on our website and are processed by Stripe. Our apps for iPhone, iPad, Android and Windows sell nothing and offer no in-app purchase. We do not receive full card numbers from Stripe. Stripe's terms also apply to the transactions it handles.

Subscriptions and trials. A subscription renews only when checkout says it renews. Unless a different lawful disclosure applies, it renews for the displayed period at the then-disclosed price until cancelled. You may cancel future renewal through the account or platform that sold the subscription. Cancellation normally leaves paid access available until the end of the current term and does not by itself create a refund. A trial converts to a paid plan only when the conversion, price, timing, and cancellation method were disclosed before enrolment. We will provide legally required notice of price or material subscription changes. A lifetime plan or grant lasts as long as we offer the part of the Service it covers and your account stays open; it is personal and cannot be transferred.

Direct-purchase promise. Unless checkout states a more favourable policy, you may ask us at hello@grindlabs.ca for a refund of an eligible plan or program bought directly from Grind Labs within seven (7) days after purchase. This contractual promise is in addition to rights under applicable consumer law. It does not apply to stones that have been used or given, or to other digital items after they have been consumed, abusive or repeated refund activity, or value already transferred outside the Service, except where law requires otherwise. We will correct verified duplicate charges, non-delivery, or technical billing errors.

Grindstones. Grindstones (“stones”) are Service credits used only for eligible features, such as making study material from a file. Your account or plan may include a number of stones each month; they come back on the first day of each month (Eastern time), and the month's stones you have not used do not carry over. Stones you buy never expire while your account is open, and they are used after the month's stones. You may give stones you bought, never the month's stones, to a friend in the app, within the limits shown there; a gift is final once sent, except that we may reverse a gift made by fraud or error. Stones have no cash value: they are not money, a bank deposit, stored value, an investment, or property, except to the extent applicable law requires a different treatment. They cannot be redeemed for cash, sold, traded for anything outside the Service, or used outside the Service, and the stones in an account are lost when the account is deleted. The displayed grant, debit, gift, promotional, and correction rules apply. We may change future stone pricing or uses prospectively, but will not use these Terms to remove a non-waivable right.

You authorize the disclosed charge and applicable taxes. You must keep billing information current. Failed payments may pause access. A chargeback does not waive amounts legitimately due and may prompt a temporary entitlement restriction while the dispute is investigated, but we will not penalize a good-faith exercise of a statutory chargeback right. Access restoration may require the payment account used and a valid receipt. You are responsible for your own internet, device, foreign-exchange, and third-party charges disclosed by their provider.

9. Third-party services

The Service may connect to identity providers, payment platforms, app stores, cloud infrastructure, communication networks, AI providers, Google Drive, user-posted links, and other third-party services. Their terms and privacy notices govern their services. We do not control their availability, content, security, pricing, account decisions, or independent processing. When you download one of our apps from the App Store, Google Play or the Microsoft Store, that store's terms cover the download and your store account.

Your instructions may cause information to move to a third party—for example, signing in with Google, opening an external link, saving to Drive, paying through Stripe, downloading an app from an app store, or submitting an AI request. Review the destination and its terms. A platform term prevails over these Terms only for the transaction or platform service it controls, and only to the extent of an actual conflict.

Our app from the App Store. For the app you download from Apple's App Store, these Terms are between you and Grind Labs Inc., not Apple. Apple is not responsible for the app or its content and has no duty to provide maintenance or support for it. If the app fails to meet a warranty that applies to it, you may tell Apple, and Apple will refund the price you paid for the app, if any; to the extent the law allows, Apple has no other warranty obligation for the app. We, not Apple, handle any claim about the app, including product liability, failure to meet a legal or regulatory requirement, consumer protection, privacy, and claims that the app or your use of it infringes another person's intellectual property. You may use the app on Apple devices that you own or control, as the App Store's Usage Rules allow, and you must follow the terms of your other providers, such as your mobile carrier, when you use it. You confirm that you are not located in a country subject to a United States government embargo or designated by it as a “terrorist supporting” country, and that you are not on any United States government list of prohibited or restricted parties. Apple and its subsidiaries are third-party beneficiaries of these Terms and, once you accept them, may enforce them against you as a third-party beneficiary. Questions, complaints and claims about the app go to Grind Labs Inc., 71 rue Papillon, Dollard-des-Ormeaux, Quebec H9B 3J7, Canada, at 514-928-7434 or hello@grindlabs.ca.

10. Availability, changes, and beta features

The Service is provided on an “as is” and “as available” basis to the extent permitted by law. Internet, devices, browsers, operating systems, providers, and experimental features can fail. Maintenance, security work, outages, capacity limits, compatibility changes, and feature evolution may interrupt or alter the Service.

We may add, modify, cap, suspend, or discontinue features. Where practical, we will give reasonable notice before materially reducing a paid feature during its paid term and will provide any remedy mandatory law requires. Beta, preview, experimental, and early-access features may be incomplete, inaccurate, changed without notice, or discontinued.

Keep independent copies of irreplaceable notes, files, exports, receipts, and records. Offline and synchronization features reduce some risks but do not guarantee against data loss. Do not rely on the Service where delay, loss, or failure could cause injury or serious harm.

11. Enforcement, suspension, and termination

You may stop using the Service, cancel future renewal, or request account deletion at any time. Cancellation of a subscription and deletion of an account are separate actions. Data handling after deletion is described in the Privacy Policy. The steps to delete your account are at grindlabs.ca/delete-account.

We may warn, remove content, restrict an entitlement or feature, suspend, or terminate access when reasonably necessary to enforce these Terms, protect users or the Service, address non-payment, investigate fraud or infringement, comply with law or a valid legal request, or respond to an urgent security or safety risk. We may act immediately for serious or repeated conduct. Where reasonable and lawful, we will explain the action and provide a contact route for review.

Termination ends your licence. Provisions that by their nature must continue—including ownership, user-content licences for retained copies, payment obligations, disclaimers, liability limits, dispute terms, and enforcement relating to earlier conduct—survive. Account closure does not erase a recipient's lawful copy, a transaction record, moderation evidence, a legal hold, or another record we must retain.

12. Disclaimers, responsibility, and liability

To the maximum extent permitted by applicable law, we disclaim implied warranties and conditions, including merchantability, fitness for a particular purpose, title, non-infringement, accuracy, uninterrupted access, and error-free operation. We do not warrant educational, exam, professional, AI, community, or user-provided content.

To the maximum extent permitted by law, Grind Labs and its directors, officers, employees, contractors, and affiliates are not liable for indirect, incidental, special, punitive, exemplary, or consequential loss; lost data, study time, opportunity, revenue, goodwill, or anticipated savings; exam, admissions, licensing, employment, clinical, or professional outcomes; reliance on AI or user content; user conduct; or third-party services.

To the maximum extent permitted by law, our aggregate liability arising from the Service or these Terms is limited to the greater of CAD $100 and the fees you paid Grind Labs for the Service during the 12 months before the event giving rise to the claim.

To the extent permitted by law, you will compensate Grind Labs for a third-party claim, reasonable cost, or loss to the extent caused by your unlawful User Content, wilful misuse of the Service, infringement of another person's rights, or material breach of these Terms. This obligation does not apply to the extent the claim was caused by Grind Labs or where applicable law prohibits it. We may control the defence after consulting you and may not settle a claim that admits your fault or imposes a non-monetary obligation on you without your consent, not to be unreasonably withheld.

These disclaimers and limits do not exclude liability for our fraud, intentional act, gross fault, or bodily or moral injury; a remedy under mandatory consumer or privacy law; or any other liability that cannot lawfully be excluded or limited. Some jurisdictions do not allow particular exclusions, so only the lawful portion applies to you.

13. Governing law, disputes, and general terms

These Terms are governed by the laws of Quebec and the applicable federal laws of Canada, without depriving a consumer of protections that the mandatory law of their home jurisdiction gives them. Before formal proceedings, we ask both sides to try in good faith to resolve the matter through hello@grindlabs.ca. This request does not shorten a limitation period or require you to abandon urgent relief, a regulator, small-claims procedure, chargeback, or another statutory remedy.

Subject to mandatory consumer venue rights, proceedings may be brought in a competent court in Quebec. These Terms do not require arbitration or waive a right to participate in a class, collective, or representative proceeding.

We may assign these Terms as part of a reorganization, financing, merger, sale, or transfer of the Service, subject to law. You may not assign your account or these Terms without our consent. If a provision is invalid, it is limited or severed only as needed and the rest remains effective. A delay in enforcement is not a waiver. These Terms and incorporated transaction-specific terms are the entire agreement about the Service and replace earlier versions prospectively. Electronic records and notices satisfy writing requirements where law permits. Neither side is responsible for delay caused by events beyond reasonable control, but this does not excuse payment already due or an obligation that law does not allow us to exclude.

14. Changes and contact

We may update these Terms prospectively as the Service, law, or providers change. We will post the updated version and its date. For a material change, we will give you notice through the Service, by email, or by another appropriate channel. If you already have an account and a change adds to your obligations or reduces ours, we will write to you at least 30 days before it applies, with the new wording, the wording it replaces, and the date it applies; you may then refuse the change and cancel without cost, penalty or cancellation indemnity within 30 days after it applies. We will seek renewed consent where law requires it. A change does not retroactively remove an accrued right or alter a completed purchase where law or the purchase terms prevent it.

Questions, legal notices, refund requests, or account concerns: hello@grindlabs.ca, 514-928-7434, or by mail to Grind Labs Inc., 71 rue Papillon, Dollard-des-Ormeaux, Quebec H9B 3J7, Canada. The current Terms are available at grindlabs.ca/terms and lagrind.ca/terms.
