AstroKnot Privacy Policy

Last updated 4 September 2026. AstroKnot is made by Tarmac Soul Productions (Tarsoul AB), Sweden.

What we collect

Nothing. AstroKnot has no accounts, no analytics, no advertising and no tracking. Your puzzles, progress, settings and streaks are stored only on your device.

Game Center

If you choose to sign in to Game Center, your daily times are submitted to Apple's Game Center leaderboard under your Game Center nickname. This is handled by Apple under Apple's privacy policy. You can play without Game Center; the leaderboard is optional.

Purchases

The one-time unlock is processed by Apple through the App Store. We never see your payment details.

Challenge links

A challenge link contains only a puzzle id, your solve time and, if you chose one, your Game Center nickname. Nothing is sent to us.

Children

AstroKnot is suitable for all ages and collects no personal data from anyone.
