Privacy
Last updated: 18 October 2026
The short version: yuzudo collects no personal data. There is no account, no sign-in, no analytics, no ads and no tracking. Everything you do in the app stays on your phone, and no data is sent to us.
The app
Your data stays on your device
Your timers, fruits, focus minutes and history are stored only on your phone. yuzudo sends no data to us.
Android backup
If backup is turned on for your phone, Android may include yuzudo’s data in your device backup, which is stored in your Google account. That backup is handled by Google under Google’s privacy policy. We have no access to it.
Purchases
yuzudo+ is a one-time purchase made through Google Play Billing. Google processes the payment. We receive no payment details.
Save / Load progress
In Settings you can save your progress to a file and load it again, for example on a new phone. This is optional. The file is encrypted. To lock it to you, it contains a salted hash of the Google account name you pick, never the name itself. The file stays wherever you keep it and is not sent to us.
Children
yuzudo is made for ages 9 and up. The app collects no personal data from anyone, including children.
