Keepline is a habit tracker. This page explains, in plain language, what data the app touches, where it lives, and — just as importantly — everywhere it doesn't go.

Keepline stores the habits you create, their schedules, and your completion history. That's it — there's no separate profile, no usage log, no device fingerprint.
| Data | Where it lives | Who can see it |
|---|---|---|
| Habits, schedules, completion history | On your device, and your own private iCloud account if signed in | Only you |
| Apple Health data (steps, workouts, sleep, water) | Read on your device only, to check off matching habits | Only you — never leaves your device |
| Purchase status (Support / Champion) | Apple's App Store systems | Apple and you — Keepline never sees your payment details |
If you turn on automatic completion for a habit, Keepline reads the relevant Health category — steps, workouts, sleep, or water — to check whether that day's goal was already met. This is read-only: Keepline never writes anything back to Health, and the data it reads is used entirely on your device to decide whether to check off a habit. It is never transmitted anywhere, including to us.
If you're signed into iCloud, Keepline uses Apple's CloudKit to sync your habits and history across your own devices. This happens inside your own private iCloud database — the same kind of storage Apple uses for your Photos or Notes. We don't operate a server of our own and can't see this data; only you, through your Apple ID, can access it.
Keepline doesn't have a backend server, a login system, or an analytics SDK. There is no way for us to see your habits, your streaks, or your Health data — the app was built so that we don't have to ask you to trust us with them.
Support and Champion are optional one-time purchases handled entirely by Apple's App Store. Keepline never receives or stores your payment information — only Apple's own systems do, governed by Apple's privacy policy.
Keepline is not directed at children under 13, and we don't knowingly collect data from anyone in that age group. Since the app has no account system or server-side storage, no personal data is ever collected from any user regardless of age.
If this policy changes, the effective date at the top of this page will be updated. Material changes will also be reflected in the app's release notes.
