Public privacy policy for One Line puzzle game
Last updated: October 18, 2026
GeNew Studio (“we”, “us”) operates the mobile puzzle game One Line. This page explains how we handle information when you use our app.
One Line is an offline puzzle game. Your progress, coins and settings are stored on your device. If you sign in to Google Play Games (Android) or Game Center (iOS), a copy of your progress is also kept in that service so it can sync across your devices. We do not operate user accounts or our own backend servers, and we do not ask for your name, email or contacts.
The app saves the following on your phone using local storage:
This data is not transmitted to our servers. We do not back it up ourselves; it is removed when you uninstall the app unless your device backup or Play Games / Game Center cloud save keeps a copy (see below).
On Android the app uses Google Play Games Services, and on iOS Apple Game Center, for leaderboards, achievements and cloud save. When you are signed in:
This data is processed by Google under Google’s Privacy Policy or by Apple under Apple’s Privacy Policy. We do not receive your Google or Apple account details. You can play without signing in, and manage or delete your Play Games profile and saved games in the Play Games app or your Google account settings (Game Center: iOS Settings → Game Center).
The app shows ads through Google AdMob:
Google may collect device and advertising-related information (such as advertising ID, IP address, and app usage signals) to serve and measure ads. This is handled under Google’s Privacy Policy.
We do not receive personal identity information from Google through this integration.
In regions that require it, the app asks for your consent before showing ads, using Google’s consent tool. You can change your choice anytime in Shop → Ad privacy options.
You can buy Premium (a one-time purchase that removes interstitial ads and unlocks all levels) and coin packs. Payment is processed by Google Play Billing or the Apple App Store, which may collect payment-related information according to their own privacy policies. We never see your payment details.
Purchase status is verified through RevenueCat, which receives a random anonymous app user ID, your purchase history for this app, and basic device information (such as OS version and country). See RevenueCat’s Privacy Policy.
The app may request:
| Permission | Purpose |
|---|---|
| Internet | Load ads and verify purchases |
| Advertising ID (Android) | AdMob ad serving and measurement |
Signing in to Google Play Games or Game Center is optional and handled by Google or Apple.
Permissions are used only for the features above.
We do not sell your personal data.
We do not share data from local app storage with third parties.
Ad-related data may be processed by Google AdMob as described in Google’s policies. If you sign in, leaderboard scores, achievements and cloud-saved progress are processed by Google Play Games or Apple Game Center. Payment data is handled by Google Play or Apple, and purchase status by RevenueCat, as described above.
Local game data remains on your device until you clear the app’s data or uninstall the app. We have no account of yours to delete. Cloud-saved progress, achievements and leaderboard entries live in your Play Games or Game Center profile; delete them there (Play Games app → Settings → Delete Play Games account & data, or iOS Settings → Game Center).
For advertising data handled by Google, refer to Google’s settings and policies (for example, Ads personalization controls on your device).
One Line is not directed at children under 13. We do not knowingly collect personal information from children.
We may update this policy from time to time. The “Last updated” date at the top will change when we do.
