Privacy Policy

Last updated: 2026-07-26

This policy explains what Strength. collects — on this website and in the iOS/watchOS app — how it's used, and the choices you have. Strength. is offline-first: your training data lives on your device first, and only syncs to power account features like backup and cross-device access.

This website

getstrength.app collects only the email address and language you submit to join the waitlist, stored in our database (Supabase) with insert-only access — we can't read, edit or export it from the browser. We don't use cookies, analytics or advertising trackers. Your language choice is saved in your browser's local storage and never sent to us.

Your account

Creating an account in the app requires an email address and username, plus your chosen sign-in method — email & password, Sign in with Apple, or Google. We store this account data, along with your subscription status, to identify you and sync your data across devices.

Your training data

Programs, training days, exercises, live sessions, sets and stats are stored locally on your device first, and sync securely to our database when you're online — so you can move between iPhone and Apple Watch, and recover your data if you switch devices.

Apple Health

If you grant permission, the app reads your heart rate, active energy and body mass from Apple Health to power live-session stats, and writes completed workouts and active energy back to Health. Health data is used solely for these in-app features — it's never used for advertising or marketing, and never sold.

Apple Music

Pro subscribers can link an Apple Music playlist to control playback during a live session. We only send playback commands — we don't collect or store your music library or listening history.

Third parties we work with

We share the minimum data each provider needs to do its job. None of them receive your data for advertising, and we don't use any analytics or ad-tracking SDKs.

  • Supabase — hosts our database, authentication and edge functions.
  • RevenueCat — manages Pro subscriptions and links your purchase to your account.
  • Apple — Sign in with Apple, HealthKit, MusicKit and App Store payment processing.
  • Google — Google Sign-In, only if you choose that sign-in method.

Storage & security

Your data is encrypted in transit. Access to your synced data is restricted at the database level, so only you can read or write your own records.

Keeping & deleting your data

You can permanently delete your account and all associated data at any time from Profile → Delete account in the app. To be removed from the website waitlist, email us and we'll remove your address.

Your rights

You can access, correct, export or delete your data at any time. If you're in the EU, UK or elsewhere with data protection laws, you also have the right to restrict or object to processing, and to lodge a complaint with your local supervisory authority. Contact us to exercise any of these rights.

Children

Strength. isn't intended for children under 13. We don't ask for or knowingly collect data from anyone under 13 — if we learn we have, we'll delete it. If you're between 13 and the age of digital consent in your country, you should have a parent or guardian's permission to use the app.

International transfers

Our service providers may process data outside your country of residence. Where this happens, we rely on the safeguards they provide (such as standard contractual clauses) to protect your data.

Changes to this policy

We'll update the date above when this policy changes, and notify you by email or in-app if a change is material.
