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:

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

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.
