OneHabit
Effective date: March 28, 2026 · OneByOne LLC
OneHabit is designed from the ground up to protect your privacy. The app does not collect, transmit, or share any personal data. Everything you enter stays on your device.
We do not collect, store, or process any of the following:
All habit entries, daily logs, streaks, notes, and reminders are stored locally on your device using Apple's SwiftData framework. This data never leaves your device and is not accessible to OneByOne LLC or any third party.
App preferences (theme, notification settings, etc.) are stored using Apple's standard UserDefaults on your device only.
OneHabit offers optional in-app purchases and auto-renewable subscriptions managed entirely by Apple through the App Store. OneByOne LLC does not receive or store your payment information. All billing, receipts, and subscription management are handled by Apple.
To manage or cancel a subscription, go to Settings → [Your Name] → Subscriptions on your iPhone.
If you enable reminders, OneHabit schedules local notifications on your device. These notifications are generated entirely on-device and are not routed through any external server.
OneHabit does not integrate any third-party analytics SDKs, advertising networks, or tracking frameworks. No data is shared with third parties.
OneHabit does not knowingly collect any information from children under the age of 13. Because the app collects no data at all, it is safe for users of all ages.
Since all data is stored locally on your device, you are in full control. You can delete all app data at any time by uninstalling OneHabit from your device. OneByOne LLC holds no copy of your data and has nothing to delete on your behalf.
If this policy changes materially, the updated version will be published at this URL with a revised effective date. Continued use of the app after a change constitutes acceptance of the updated policy.
