Your training stays yours.

Last updated July 21, 2026

45 lb is built for training, not data harvesting. You sign in with Apple, your workouts live in your 45 lb account, and that account exists for exactly one purpose: running the app for you. This page lists everything we hold and everything we refuse to do with it.

What we collect

When you sign in and train, our servers store: the name and email address Apple shares at sign-in (choose "Hide My Email" and we receive a private relay address instead), anaccount identifier (we never see your Apple password), and your training data — your routines, custom exercises, sets, weights, reps and workout history. If you send feedback from the app, we also receive your message along with basic device details (app version, iOS version, device model) so we can reproduce what you're describing.

Where your data lives

Your training data is stored on your device and synced to 45 lb's own servers over an encrypted connection, so signing in on a new iPhone brings your history with it. It is notstored in iCloud.

What we never do

No advertising, no third-party analytics SDKs, no tracking across other apps, and no selling or sharing of your data — with anyone, for any reason. Your data is used to run the app for you, and for nothing else.

Apple Health

If you turn on "Save workouts to Apple Health", finished workouts are written to the Health app, and during a session the Apple Watch app reads your heart rate to show it live. Health data stays on your device and in Apple Health — it is never sent to our servers.

The exercise catalog

45 lb downloads a shared, read-only catalog of exercises and routine templates from a public database so the library can grow without an app update. This is a one-way download of reference content — no personal data is sent in order to fetch it.

Deleting your data

Deleting your account removes your data from our servers. You can also email help@45lb.app from any address and we will delete it for you.

Children

45 lb is not directed at children under 13 and does not knowingly collect information from them.

Changes

If this policy changes, the updated date above will change with it. Material changes will be reflected in an app update.
