TERMS OF SERVICE: GRIND

Last Updated: March 14, 2026

Welcome to GRIND. These aren't standard terms of service designed to gently hold your hand. By using the GRIND mobile application ("App"), website ("Website"), or related services (collectively, "Services"), you agree to the following terms. If you do not agree to these terms, delete the App and leave.

The GRIND App is operated by Zubro Ltd. ("Company," "we," "us," or "our"). These Terms apply universally, with provisions designed to comply with major international jurisdictions.

1. ACCEPTANCE & PHILOSOPHY

By accessing or using our Services, you are bound by these Terms. GRIND is designed to be tough, unyielding, and occasionally abrasive. You accept that the App will judge your performance frankly, and your "XP" or "Level" will drop below zero if you fail to act. We will not apologize for the truth, nor will we alter the App's tone because your feelings are hurt. You acknowledge that GRIND is a discipline app that will challenge you.

2. MEDICAL DISCLAIMER & ASSUMPTION OF RISK

READ THIS CAREFULLY. IT LIMITS OUR LIABILITY.

GRIND is not a healthcare provider, and our Services should not be considered medical advice.

  1. Inherent Risks: You acknowledge that bodyweight fitness training involves inherent risks of severe physical injury, permanent disability, or death.
  2. Consult a Physician: Always consult a physician before beginning any workout regimen recommended by GRIND.
  3. No Liability: You expressly assume all risks associated with your use of the Services. We, our employees, and our affiliates shall not be liable for any injury, health complications, damages, or death resulting directly or indirectly from your use of the exercises, routines, algorithmically generated targets, or advice provided within the App.
  4. Target Intensity Risks: The App dynamically generates targets, which can scale up to 130% of your baseline metrics. It is your sole responsibility to cease exercising if you experience pain, dizziness, or severe discomfort.

3. SUBSCRIPTIONS, BILLING, AND NO-REFUND POLICY

GRIND requires an active subscription or trial to function. There is no free tier; there is no "gentle mode."

  1. Payments: Subscriptions are managed natively via Apple (App Store) or Google (Play Store) using RevenueCat. By starting a subscription, you authorize the applicable platform to charge your payment method on a recurring basis.
  2. Offline enforcement: The Subscription status is definitively managed by our cloud services. Local circumvention attempts will result in an immediate block from the Services.
  3. Cancellation: You must cancel your subscription through your respective platform store at least 24 hours before the end of the current billing period to avoid automatic renewal. Deleting the app does not cancel your subscription or stop your billing.
  4. NO REFUNDS (Global, except where legally mandated): To the maximum extent permitted by applicable law, all payments are non-refundable. We will not refund you because you failed to train, allowed your XP to go negative, or disliked tone of the App.

Statutory Rights of Withdrawal (Cooling-Off Period)

If you reside in a jurisdiction that grants you a statutory right to withdraw from a digital content contract within a specific period (e.g., 14 days) without penalty: By starting to use the GRIND App during this window, you expressly consent to immediate performance of the contract and acknowledge that you lose your right of withdrawal once the digital content is provided.

4. USER CONDUCT & ZERO TOLERANCE

Your accountability is a private contract between you and GRIND, but we maintain the right to enforce standard platform rules:

  1. No automated data harvesting, API abuse, or attempts to reverse-engineer the proprietary generation algorithms running on our backend.
  2. No manipulation of local database caches to spoof XP, levels, or completion timestamps.
  3. Violation of these rules gives us the right to instantly terminate your account, obliterate your data, and permanently ban your device without a refund.

5. ACCOUNT DELETION & DATA RETENTION

"Start Over" vs Deletion: GRIND offers a "Start Over" nuclear option that wipes your progress. Complete account deletion (and thus data removal from Supabase) requires you to contact support at support@grind.zubro.xyz.

Upon account deletion, all personal data, including historical training logs and metrics, will be purged strictly adhering to applicable global data protection regulations. However, anonymized statistical data may be retained to further improve our algorithmic models.

6. INTELLECTUAL PROPERTY & ALGORITHM

The brand "GRIND", all visual assets ("brutalist dark modes", UI layouts), copywriting tones, the XP algorithms, and the underlying source code run on our backend are the exclusive intellectual property of the Company. You are granted a limited, non-exclusive, revocable license strictly to access the App for personal use.

7. DISCLAIMER OF WARRANTIES

THE SERVICES ARE PROVIDED "AS IS" AND "AS AVAILABLE." WE DISCLAIM ALL WARRANTIES, EXPRESS OR IMPLIED, INCLUDING FITNESS FOR A PARTICULAR PURPOSE, MERCHANTABILITY, AND NON-INFRINGEMENT. WE DO NOT WARRANT THAT THE SERVICES WILL BE UNINTERRUPTED, BUG-FREE, OR SECURE.

We are not liable if you lose your progress due to device destruction, loss of connection before a mandatory sync, or database resets.

8. LIMITATION OF LIABILITY

TO THE MAXIMUM EXTENT PERMITTED BY LAW, IN NO EVENT SHALL THE COMPANY, ITS DIRECTORS, OR EMPLOYEES BE LIABLE FOR ANY INDIRECT, PUNITIVE, INCIDENTAL, SPECIAL, OR CONSEQUENTIAL DAMAGES ARISING OUT OF OR IN ANY WAY CONNECTED WITH THE USE OF THE SERVICES, OR FOR ANY INFORMATION, SOFTWARE, PRODUCTS, AND SERVICES OBTAINED THROUGH THE SERVICES. IN NO EVENT SHALL OUR AGGREGATE LIABILITY EXCEED THE AMOUNT PAID BY YOU FOR THE PLATFORM IN THE PREVIOUS 12 MONTHS.

9. GOVERNING LAW & INTERNATIONAL JURISDICTION

1. Data Privacy & Transfer: Your data is handled in strict compliance with applicable global data protection regulations. By using the App, you explicitly consent to the cross-border transfer of your personal data to our cloud infrastructure globally.

2. Governing Law & Dispute Resolution: These Terms shall be governed by the laws of the jurisdiction in which our Company is registered, without regard to conflict of law principles. Any dispute arising from your use of GRIND must be resolved by binding arbitration in that jurisdiction, and you waive your right to participate in a class action lawsuit or class-wide arbitration.

3. Consumer Protection Rights: If you reside in a jurisdiction with mandatory consumer protection laws that cannot be derogated from by contract, nothing in these Terms deprives you of the protection afforded by those laws, and any unavoidable disputes may be resolved in your country of habitual residence.

10. MODIFICATIONS TO THE TERMS

We reserve the right to modify these Terms. When changes are made, we will update the "Last Updated" date at the top of this document. Continued use of GRIND after changes signifies your acceptance. If you reject the new terms, your only recourse is to cancel your subscription and terminate your account.
