Terms of Service
& Privacy Policy
1. About Compound
Compound is an AI-powered workout tracking application currently in a closed pilot phase. It is developed and operated by Varoon Seelan ("we", "us", "our"). The application allows users to log workouts, track progress, and receive AI-generated coaching and programme recommendations.
During the pilot phase, access is by invitation only. Compound is not yet a commercial product. These terms govern your use of the application and our handling of your personal data during the pilot.
2. Acceptance of Terms
By creating an account and using Compound, you confirm that you have read, understood, and agreed to these Terms of Service and Privacy Policy. If you do not agree, do not use the application.
You are also required to accept these terms within the application on first login. Your acceptance is recorded with a timestamp in our database.
3. Who Can Use Compound
You must be aged 18 or over to use Compound. By creating an account you confirm you meet this requirement.
During the pilot, access is restricted to individuals who have received a direct invitation. You may not share your invitation or account credentials with others.

5. How We Use Your Data
We use the data described in Section 4 for the following purposes:
Providing the service
Your data is used to run the app — displaying your workout history, calculating your Strength Score, tracking PRs, generating progress charts, and powering all other in-app features.
AI features
When you use AI features (programme generation, plateau advice, travel mode, block review), your profile and training history are sent to Anthropic's Claude API to generate personalised responses. Your email address is never sent to Anthropic. Data is keyed to an anonymous internal user ID. See Section 6 for more on third-party services.
Product development
During the pilot, we use aggregated and anonymised usage patterns to understand how the app is used, which features are working, and what to improve. We do not build individual profiles for marketing purposes.
What we do not do
We do not sell your data to third parties. We do not use your data for advertising. We do not share your personal data with any party not listed in Section 6 without your explicit consent.
6. Third-Party Services
Compound uses the following third-party services to operate. By using Compound, you acknowledge that your data may be processed by these providers under their respective privacy policies.
| Provider | Purpose | Data shared |
|---|---|---|
| Supabase | Database and authentication (user accounts, session storage, all app data) | All data described in Section 4 |
| DigitalOcean | Server infrastructure (the app and AI proxy are hosted here) | Hosting only — DigitalOcean does not access app data |
| Anthropic (Claude API) | AI coaching features — programme generation, plateau advice, travel mode, block review | Your training history, profile data (keyed to anonymous user ID — email not shared) |
| Resend | Transactional email (invite links, password resets) | Your email address only |
7. Data Retention & Deletion
We retain your data for the duration of the pilot programme and for a reasonable period afterward (up to 12 months) for development and reference purposes, unless you request earlier deletion.
You may request complete deletion of your account and all associated data at any time by contacting us directly (see Section 13). Deletion will be completed within 14 days of receiving your request.
You can export all your data at any time using the in-app Backup function (Programme → Backup → Export Data). This provides a complete JSON export of your account data.
8. Your Rights
You have the following rights with respect to your personal data. To exercise any of these rights, contact us using the details in Section 13.
| Right | Details |
|---|---|
| Access | Request a copy of all personal data we hold about you. The in-app Export function provides this directly. |
| Correction | Update or correct your profile data within the app at any time via the Body and Programme screens. |
| Deletion | Request that all your personal data be permanently deleted from our systems. Contact us directly to action this. |
| Portability | Export your data in a machine-readable format (JSON) at any time via the in-app Export function. |
| Withdrawal | Withdraw consent and stop using the application at any time. Your data will be retained unless you also request deletion. |
| Objection | Object to your data being used for product development purposes. Contact us and we will restrict processing to service delivery only. |
9. Health & AI Disclaimer
Not medical advice
Compound is a fitness tracking tool. Nothing in the application — including AI-generated training programmes, coaching advice, plateau recommendations, or any other content — constitutes medical advice, diagnosis, or treatment. Always consult a qualified healthcare professional or registered physiotherapist before starting a new training programme, particularly if you have any pre-existing health conditions, injuries, or are returning from a period of inactivity.
AI limitations
AI-generated content within Compound is produced by a large language model (Claude by Anthropic). While we have designed the prompts carefully and the AI uses your training history and profile data, AI output can be incorrect, incomplete, or inappropriate for your specific circumstances. AI coaching in Compound is not a substitute for guidance from a qualified personal trainer or strength and conditioning coach.
Beta software
Compound is pre-release software. Features may change, be unavailable, or contain bugs. Data loss, though unlikely, is possible. We strongly recommend using the in-app Backup function regularly to export your data as a precaution.
10. Acceptable Use
You agree not to:
— Share your account credentials or allow others to use your account
— Attempt to access, extract, or interfere with other users' data
— Use the application in any way that violates applicable law
— Attempt to reverse-engineer, copy, or redistribute the application or its code
— Use the application if you are under 18 years of age
Breach of these terms may result in your account being suspended or terminated.
11. Security
We take reasonable technical and organisational measures to protect your data. Your data is stored in Supabase with row-level security (RLS) — each user can only access their own data. Supabase database connections and API calls use TLS encryption.
12. Changes to These Terms
We may update these Terms of Service and Privacy Policy during the pilot. We will notify you of any material changes by email (to the address associated with your account) at least 7 days before the changes take effect. Continued use of the application after that date constitutes acceptance of the revised terms.
The date at the top of this document will always reflect the version you are reading.
