Privacy Policy
ONE does not collect personal information.
1. What we collect
Nothing. ONE has no accounts, sign-in, servers, ads or analytics. mooha never sees or receives what you write or how you use the app.
2. What is stored on your device
Your affirmation; your ONE thing for this year, month and week and its state (in progress, done, let go); start and end dates; your next step and the number of steps taken; the line you leave when you look back; things you chose not to do; and your settings (reminder, appearance, accent color) are stored only on your device. Widgets and the Lock Screen read the same on-device store.
3. Notifications
The weekly look-back reminder is a local notification scheduled on your device. It does not pass through any server.
4. Contact email
If you email us from the app, we use your email address and message (and the device model, iOS and app version if included) only to reply, and delete them once the conversation is finished.
5. Deleting your data
Settings ▸ Delete All, or deleting the app, removes data on the device. Once a conversation is finished, we delete your email from both the inbox and the trash.
6. Your rights
Everything you enter stays on your device, so you can view, edit and delete it in the app yourself. To see or delete an email you sent us, write to [email protected]. We act on it within 10 days.
7. How we keep it safe
mooha has no servers, so we keep no copy of your information. We read support email only in a mail account protected by two-step verification.
8. Children
ONE collects no personal information from anyone, including children. If you are under 14, please email us together with a parent or guardian. If we find we have email from a child, we delete it right after replying.
9. Changes
If this policy changes, we will post it on this page with a new effective date.
