1. Who is responsible

Maximum Capacity, LLC (the training business whose trainers invite you) is the data controller: it decides why and how your data is used. The software developer who builds and operates the app on Company's behalf is a data processor, acting only on Company's instructions under a written agreement. Contact for everything in this policy: support@maxcaptraining.com.

2. What we collect

The app is invitation-only; there is no public sign-up. Everything below exists because your trainer invited you and you accepted.

We do not collect precise location, contacts, calendars, health-platform data (Apple Health, Google Fit, wearables), or payment card details. There is no payment processing in the app.

3. How it is used

We do not sell personal data, and we do not use it for advertising or profiling.

4. AI processing — Gemini on Vertex AI

Two features use Google's Gemini models through Vertex AI in Google Cloud, in Company's own Google Cloud project. Google Cloud's terms apply: under Vertex AI's data-governance commitments, prompts and outputs are not used to train Google's models.

Food recognition

When you ask for a nutrition estimate, we send Gemini: the food description you typed and, for barcodes we could not resolve from Open Food Facts, the barcode number (and a photo of the label, only if you chose to attach one). Nothing else — no name, no history. The result is an estimate you confirm before it is saved. The app no longer offers photographing a plate; any plate photos taken with earlier versions are covered by the retention rule below.

The assistant

When you send a message, we send Gemini: your message, the recent turns of that conversation, and — only when the assistant asks for it through defined tools — the specific data needed to answer, such as your current credit balance, upcoming sessions, recent workouts, or today's macro totals. A trainer's assistant can additionally read the data of the trainer's own clients. The assistant cannot change anything itself: it proposes, and you apply. Conversations are stored so you can revisit them and can be cleared by you (clients) or by staff (see §8).

Barcode lookups go to Open Food Facts (a public, non-profit database) with the barcode number only.

5. Processors and where data lives

ProviderWhat forWhere
Google Cloud / Firebase (Google LLC)Authentication, database (Firestore), file storage, Cloud Functions, push notifications (FCM), reCAPTCHA Enterprise (website contact form), Vertex AI (Gemini)United States (us-east1)

Each provider acts as a processor or independent service under its own terms. Data is stored in the United States.

6. No analytics, no advertising

The app and this website contain no analytics SDK, no advertising SDK, and no third-party trackers. We do not use cookies on this website. Crash reports are not collected by a third-party service. The only third-party code on this website is Google Fonts and, on the contact form when you focus it, reCAPTCHA Enterprise to stop spam.

7. Retention

8. Deleting your account

You can delete your account yourself, in the app, at any time: Profile → Account → Delete account. You will be asked to type a confirmation. Deletion is immediate and cannot be undone. It destroys:

Your trainer is notified that the account was deleted. If you are a trainer, you must release or reassign your active clients first; your pending invites are revoked. If you no longer have access to the app, see Delete your account for how to ask us to do it.

9. Your choices and rights

10. Security

Data is encrypted in transit (TLS) and at rest by Google Cloud. Access is enforced by per-document security rules so a client can only read their own record and a trainer only their own clients; privileged actions run in server-side functions and are written to an audit log. Accounts are invitation-only. Email/password accounts must verify their email. No system is perfectly secure; if we learn of a breach affecting you, we will tell you.

11. Age

The service is for adults. You must be 18 or older to hold an account. We do not knowingly collect data from anyone under 18; if you believe we have, contact us and it will be deleted.

12. Changes and contact

If this policy changes materially, we will notify you in the app before the change takes effect. The effective date at the top is the version you are reading.
