Ruleline is a puzzle game made by Kyajo Tech.

Last updated: 2026-10-24

The short version

Ruleline does not collect, store on our servers, or share any personal data. The game works fully offline, and everything it saves stays on your device.

What the app stores, and where

The app saves the following only on your device, in its private app storage:

• Your campaign progress: which levels you have completed, and for each one the best shape score, stars, points, and number of attempts.
• Your Mosaic Collection: the geometry of up to 24 rare traces you have drawn, and the level each was found on.
• Your discovery streak: how many consecutive days you found a new mosaic, and the date of the last one.
• Your settings: music, effects, haptics, appearance (system, light, or dark), color assist, high contrast, reduced motion, and whether you have seen the first-launch introduction.

This data never leaves your device. We cannot see it, and it is not included in Android cloud backups. You can delete it at any time from Settings › Clear local data, or by uninstalling the app.

What the app does not do

• No account or sign-in.
• No internet connection: the app does not request network access.
• No analytics, crash reporting, or tracking SDKs.
• No advertising or ad identifiers.
• No in-app purchases.
• No access to your contacts, photos, location, camera, or microphone.

When you choose to leave the app

A few Settings rows hand something to another app on your phone, only when you tap them:

• Privacy policy, Terms, About the studio, Rate us open the page in your browser or in Google Play.
• Share the app passes a short invitation with the Play link to Android's share sheet; you pick where it goes.
• Contact & feedback and Report a bug open your mail app with a draft addressed to us. A bug report includes the app version and your Android version so we can reproduce the problem. Nothing is sent unless you send the email yourself.

Permissions

The app uses the vibration permission only to play haptic feedback during play, and only when haptics are switched on in Settings.

Children

Ruleline does not collect personal information from anyone, including children.

Changes to this policy

If a future version adds features that handle data differently, for example ads, analytics, or cloud sync, we will update this policy before that version is released and change the date above.
