Privacy Policy

FitPlus AI · Last updated 21 April 2026

This policy explains what FitPlus AI collects, where it lives, who we share it with, and the controls you have. We keep it short and in plain English.

What we collect

Account info: name, email, hashed password, and (for trainers) a certification ID you provide.

Profile data you enter yourself: goal, age, injuries, body metrics, workout ratings, wellness check-ins, before/after photos.

Device-generated data while you use the app: workouts completed, AI chats you send, wearable readings (when you connect a Bluetooth device).

Payment details are never stored by FitPlus — card payments are handled by Stripe on Stripe's own secure checkout pages.

Where your data lives

By default, everything is stored on your device in the browser's localStorage — it does not leave your phone unless you use a feature that requires an external service (see "Who we share it with" below).

We do not operate a database that mirrors your data. If you uninstall the app or clear your browser data, the information is gone.

Who we share it with

Anthropic (Claude AI): the AI Coach sends your current chat message + a short summary of your recent activity so it can reply. See anthropic.com/privacy.

RapidAPI (ExerciseDB): exercise look-ups send the exercise name only.

EmailJS: when a trainer invites a client, the client's name + email + a welcome message are forwarded so the email can be sent.

Stripe: card payment + subscription processing, handled entirely on Stripe's secure pages. See stripe.com/privacy.

Unsplash: hero images are loaded from Unsplash's CDN — standard IP-address logging applies.

We do NOT use analytics SDKs (Sentry, PostHog, Mixpanel, Google Analytics). No behavioural tracking.

Your rights

Right to access: Account → Data & Privacy → Export My Data. You get a JSON file with everything we store for you.

Right to delete: Account → Data & Privacy → Delete My Account. One-click wipe of your profile, program, photos, chats, wellness log, and biometric credential.

Right to object: disconnect Bluetooth, disable notifications, or stop using the AI Coach at any time — each is opt-in.

Children

FitPlus is not intended for anyone under 16. Please don't create an account if you're younger than that.

Changes

We'll update the "last updated" date at the top of this page and show a one-time banner when material changes happen.
