Privacy policy for Untangle
Last updated: 1 October 2026
Untangle has no account, no sign in and no ads. This page explains the little it does with information, and names the one third party involved.
Analytics
The game sends anonymous usage events (for example, that a board was cleared) to Google Firebase Analytics, so the game can be improved. These events are not linked to a name, email address or any other personal identifier. This is the only thing the app sends off the device.
What is stored, and where
Untangle keeps a small amount of information on the device, in the app's own private storage, so that a game can be resumed:
- which level has been reached, and which chapter is chosen
- points and streak
- the fewest moves each level has been cleared in
- the cards collected, each carrying one short line
- whether today's daily knot has been played, and how it went
None of it leaves the phone. It is not backed up to any server operated by us, because there is no such server. It is not readable by other apps.
Notifications
Settings has one optional reminder for today's knot, off by default. Turning it on schedules a single local notification a day, entirely on the device using Android's own notification system; nothing about turning it on or off, or the reminder itself, is sent anywhere. Turning it off, or never turning it on, is the default and needs no action.
Deleting it
Uninstalling Untangle removes all of it. There is nothing else to request, and nobody to request it from, because no copy exists anywhere else.
What is not done
- No account, sign in or profile
- No advertising, and no advertising identifier is read
- No location, contacts, camera, microphone or file access
- No data sold or shared with anyone, for any purpose
Children
Untangle is suitable for all ages and collects no personal information from anyone, including children.
Third party components
The app plays bundled sound files using an open source component called
audioplayers, which reads files packaged inside the app and has
no network access of its own.
Changes
If this policy ever changes, the date at the top will change with it, and any release that begins collecting information will say so plainly in its release notes before it does.
