Putter privacy policy
Last updated September 21, 2026
Putter collects nothing. The Android app isn’t allowed to use the internet: its network permission is removed, so it can’t send anything off your phone, to us or to anyone else. The iPhone app doesn’t connect to the internet either. iPhone has no setting that forbids it the way Android does, so there it’s a promise about how the app is built rather than a lock the phone enforces.
What stays on your phone
Your streak, which is a few numbers, and whatever you write in the scratchpad. Both live in the app’s private storage.
On Android they’re excluded from Google backups and from device-to-device transfer, so they aren’t uploaded anywhere and they don’t follow you to a new phone.
On iPhone they can be included in your phone’s own iCloud or computer backup, the same as any app’s data. That backup is yours, and none of it comes to us.
When something leaves
Only if you tap “Send it somewhere” at the end of a buffer. Your note goes to whichever app you pick in your phone’s share sheet. Putter doesn’t find out where it went.
Permissions
On Android, three things.
Do Not Disturb access, to turn it on for a buffer and put your own setting back afterwards.
A foreground service, so a running buffer isn’t shut down halfway through.
Starting after a restart, so that if your phone restarts during a buffer, your Do Not Disturb setting still gets put back.
On iPhone, none. iPhone doesn’t let an app turn on Do Not Disturb or a Focus, so Putter leaves that switch to you.
What Putter doesn’t have
No account, no analytics, no ads and no crash reporting.
Deleting it
Uninstall Putter and everything it stored goes with it.
