Privacy Policy

Last updated 3 November 2026

The short version

Arnoldoku doesn’t collect any information about you. There are no accounts, no ads, no analytics and no tracking. Your progress stays on your device.

What the app stores

To save your game, Arnoldoku keeps a small amount of information in the app’s own storage on your device: the levels you’ve solved and their stars, your best times, your Daily Challenge streak, your hint count, any puzzle you’re partway through, and your sound, music and vibration settings.

This never leaves your device. It isn’t sent to me or to anyone else, and it isn’t linked to you. You can delete it at any time with Settings › Wipe all progress, and deleting the app deletes it too.

What the app doesn’t do

  • It doesn’t ask for your name, email or any other personal details.
  • It doesn’t use analytics, advertising or tracking services, or any third-party code that collects data.
  • It doesn’t connect to the internet. Puzzles are made on your device, and the game plays fully offline.
  • It doesn’t ask for access to your contacts, photos, location, camera or microphone.

Links to other sites

The Credits in the app link to TikTok, Instagram and the music and sound creators’ websites. Those open outside the app, and the sites’ own privacy policies apply there.

The App Store

Downloads, updates and any reviews you leave are handled by Apple under Apple’s Privacy Policy. Apple may share anonymous, combined download and crash statistics with developers if you’ve agreed to that in your device’s settings.

This website

This website doesn’t use cookies, analytics or trackers. Like any website, its hosting provider receives standard technical information, such as your IP address and browser type, to deliver pages and keep the site secure.

Children

Arnoldoku is suitable for all ages. Because it collects no personal information from anyone, it collects none from children.

Changes

If this policy changes, the new version will be posted here with a new date. If the app ever starts collecting information, this page will say so before it does.
