Serious Reps

Your data

Privacy Policy

Effective 26 September 2026

The short version. Serious Reps keeps your data on your phone. There are no ads, no analytics and no tracking, and there are no third-party SDKs in the app. The coach runs on your phone. Apple Health data stays on your phone: it is never put in your iCloud backup, never sent to a server and never used for advertising. Two things can leave your phone, and only if you turn them on: a backup to your own private iCloud, which we can't read, and squads, if you join one.

1. Who we are

Serious Reps is an iPhone, iPad and Apple Watch app for body recomposition: building muscle and losing fat around the middle. It is made by an independent developer. In this policy "we" means the developer of Serious Reps and "you" means the person using it.

Questions or requests about your data: seriousreps@starthing.space.

2. What stays on your phone

You don't need an account to use Serious Reps. Everything you enter or record is kept on your device:

This data is stored in the app's own files with iOS data protection. The main file is readable only after you have unlocked your phone once since it last restarted, so that Siri, your watch and the rest timer can save while the phone is in your pocket. Photos, voice notes, meal photos and set clips use iOS's strongest file protection: they can only be read while your phone is unlocked.

Serious Reps' files are left out of iCloud and computer device backups on purpose. The only copy that leaves your phone is the optional iCloud backup below, so its settings really decide what goes.

A few settings for this phone only, such as appearance, the Face ID lock and the backup switches, are kept in the app's own settings on the device.

3. iCloud backup (optional, off until you turn it on)

In Settings › Backup & privacy you can turn on Back up to iCloud. The backup is a single record in the private database of your own iCloud account (Apple CloudKit). We can't see it or read it. Apple stores it encrypted, and if you turn on Advanced Data Protection it is end-to-end encrypted.

What's in it

What's never in it

Serious Reps backs up when you tap Back up now, and quietly when the app goes to the background if backup is on and it has been at least six hours since the last one. Restoring always shows you the date and device of the backup first.

4. Apple Health

Serious Reps only connects to Apple Health when you choose to: Settings › Health › Connect Apple Health, or Fill from Health in the wake-up check-in. Nothing asks for Health access when the app opens. You choose exactly what Serious Reps may read and write on Apple's own permission screen, and you can change it any time in the Health app.

What Serious Reps reads, and why

Health figures only suggest. Nothing in Serious Reps changes until you tap to accept it. Serious Reps leaves out the samples it wrote itself, so they never come back as suggestions.

What Serious Reps writes, and why

Everything written is something you logged. If you undo a food in Serious Reps it is removed from Health too.

What Serious Reps never does with Health data

On Apple Watch, Serious Reps reads your heart rate during a workout, and your resting heart rate, to tell you when you're ready for the next set. That stays on the watch.

5. Squads (optional)

Squads are small invite-only groups for training with friends. They are the only part of Serious Reps that sends data to a server we run, and only if you create an account. If you never join a squad, this part doesn't apply to you: nothing is sent anywhere.

Squads are hosted on Supabase, which stores the data on our behalf. When you use squads, this is what is stored:

Every row carries your account's user ID. Other members see only the squads they belong to, and blocking hides content both ways. Your Health data, journal, photos, voice notes and coach conversations are never sent to squads. Requests are sent over HTTPS and nothing from squads is cached on your phone. Your sign-in is kept in the iOS Keychain.

6. Camera, LiDAR, microphone, photos, location and Face ID

Serious Reps asks for each permission the first time you use the feature that needs it, never at launch.

7. The coach

The coach runs entirely on your phone. On phones with Apple Intelligence it uses Apple's on-device model; otherwise the built-in Learn chapters answer. Every reply says which one answered. Nothing you ask the coach, and none of your numbers, is sent to us or to any other company. The coach can read your plan, lifts, protein, check-ins and recovery, but never your journal, photos or period days. Conversations are kept on your phone, and you can clear them in the coach.

8. Siri, Shortcuts and the Action Button

Serious Reps' Siri and Shortcuts actions (such as "Log a palm of protein in Serious Reps" or "Start today's workout in Serious Reps") run on your phone. When you log something while your phone is locked, it is kept in a small file on the phone until Serious Reps next opens and takes it in. Serious Reps sends nothing about these actions anywhere. Apple's handling of what you say to Siri is covered by Apple's own privacy policy.

9. Apple Watch

The watch app and your iPhone talk directly using Apple's WatchConnectivity. The phone sends the workout (exercise names, sets, target reps and weights, and your units). The watch sends back each set you confirm: the reps, the weight and, when it counted them, the reps it counted from your wrist's motion. Wrist motion and heart rate are read on the watch and not uploaded. The watch runs a workout session so it can keep reading your heart rate with your wrist down, but it doesn't save that workout to Health; your iPhone saves the finished session once.

10. Serious Reps Plus, notifications and feedback

11. What we don't do

The only services Serious Reps talks to are Apple's (iCloud, Apple Health, Apple Maps, Siri, the App Store) and our Supabase project, if you use squads.

12. Keeping and deleting your data

We keep squad data only while your account exists. Everything else is on your phone or in your own iCloud, under your control.

You can also email us to ask what squad data we hold about you, to correct it or to delete it.

13. Age

Serious Reps is rated 16+ and is not meant for anyone under 16. The app only accepts ages from 16. We don't knowingly collect data from children. If you think a child has created a squad account, email us and we'll delete it.

14. Changes to this policy

If we change what Serious Reps collects or how it's used, we'll update this page and its effective date before the change ships, and say so in the app's release notes. If a change would send data somewhere new, the app will ask you first.
