Privacy Policy
Last updated 24 August 2026
OneStreak: Habit Tracker does not collect, store, or transmit any personal information. There is no account, no sign-in, no backend, and no data sync of any kind. The app has no way to identify you.
What the app does on its own: nothing leaves your device. Your habit, your completion dates, your streak and your widget settings are stored locally in the app's own container. There is no analytics SDK and no advertising SDK anywhere in the app.
What stays on your device
- Your habit and its completion dates. The habit you pick and every day you log are stored on-device, in a container shared between the app and its home-screen widget so the widget can read and update your streak without the app opening. They never leave the device.
- Archived habits. If you switch habits, the previous one and its history are archived locally so your past streaks are preserved. This is also stored only on your device.
- Widget appearance settings. Your chosen accent colour is stored locally and used only to draw the widget.
-
Usage events (app launched, habit selected, streak
logged, habit switched, purchase completed, review prompt shown). These
are written to Apple's local system log (
OSLog) for on-device debugging only — they are never sent anywhere, not even to us.
The subscription
OneStreak offers an optional subscription, OneStreak Pro, which unlocks streak insights, the habit archive, and custom widget styles. The core of the app — picking a habit, tapping the widget to log it, and seeing your streak — is free and stays free.
Purchases are handled by Apple's StoreKit and by RevenueCat, the third-party service OneStreak uses to validate the subscription and keep it working if you reinstall or move to a new device.
To do that, RevenueCat receives an anonymous, app-specific identifier (not your Apple ID or name) plus transaction data from Apple — product purchased, price, date, and renewal status. It does not receive your habit, your completion dates, your streak, or anything else you enter in the app. RevenueCat's own privacy policy is at revenuecat.com/privacy.
Payment itself is processed entirely by Apple. OneStreak never sees your card details, billing address, or Apple ID — that transaction is governed by Apple's Privacy Policy. Subscription terms are set out in our Terms of Use.
What we receive
Nothing directly. If you download OneStreak from the App Store, Apple may share aggregate statistics such as download counts, subscriber counts and territory with us as the developer — that data comes from Apple and is not personally identifying. If you email us for support, we receive whatever you put in that email.
Your data, and removing it
Because nothing is collected or transmitted, there is no account to close and no data held by us to access, correct, export, or delete. Everything the app has saved lives in its container on your device — deleting the app removes it, including your habit history and any widget data.
Children
OneStreak is not directed at children and does not knowingly collect information from anyone, including children.
Changes to this policy
If a future version of OneStreak ever needs to collect or transmit data — it has no plans to — this policy will be updated before that version ships.
