Privacy Policy
Lineburst is a block puzzle game for iPhone and iPad made by Asgar Amrahov. This policy explains what data the app handles, in plain language.
No accounts and no sign-in. Your game data — scores, run history, your saved game, your settings — stays on your device. Two Google services are involved: AdMob, which serves the game's ads, and Firebase, which receives anonymous, aggregate measurements of how the game is played and reports crashes. Ads are personalized only if you allow tracking when the app asks, and Premium removes every ad.
Data stored on your device only
The app saves the following locally, and only locally:
- your best score, run history, and statistics;
- your in-progress game (so you can resume it);
- your Adventure progress and the pictures you have completed;
- your settings (sound, haptics, color-blind mode, theme).
This data is not transmitted to us and is deleted when you delete the app. We have no servers and receive nothing.
iCloud sync (Apple)
If you are signed in to iCloud, a small set of this data — your best score, Zen totals, achievement progress, Adventure progress and completion dates, earned themes, and your settings — is mirrored between your devices through Apple's iCloud key-value storage, so a new iPhone or an iPad picks up where the other left off. Apple processes this data under your own Apple ID and its iCloud terms; it never passes through us and we cannot read it. Your in-progress games and your run history stay on the device they were played on. If iCloud is signed out or unavailable, the app simply works locally, exactly as before. There is nothing to opt into or out of beyond your device's own iCloud settings.
Usage and crash data (Google Firebase)
To decide what to improve, the app sends anonymous measurements of how it is played. This is aggregate and deliberately coarse:
- one summary per finished run: which mode, and ranges rather than exact values — a score band, a band for how many pieces were placed and lines cleared, a band for how long the run was actively played, and the highest combo reached;
- which screens are opened, which buttons are used (theme chosen, a setting toggled, the continue offer taken or declined, the paywall opened and from where), and whether an ad was available;
- crash and error diagnostics, with the current screen and a coarse indication of how far into a run you were.
What is never sent: your exact score, your run history, your saved game, your settings, the daily puzzle you played, or any text. This measurement never collects the advertising identifier, whatever you answer to the tracking prompt below, and no account or identifier of our own is ever attached to it. It cannot be used to identify you or your device to us.
In the European Economic Area and the United Kingdom none of this is collected unless you give consent in the dialog the app shows before ads are served. If you decline, no usage or crash data is collected either — the same choice covers both.
Elsewhere this measurement is on, and the app does not offer a separate in-app switch for it. Because it is anonymous, aggregate and never linked to you or to an identifier we create, there is no personal data for us to look up, export or delete on request — we hold no profile of you. Deleting the app stops all of it.
How Google processes data on our behalf as a processor is described at policies.google.com/privacy and firebase.google.com/support/privacy.
Live configuration (Firebase Remote Config). The app also fetches, at launch and about twice a day, a small set of configuration values from Firebase Remote Config. Version 1.6.0 fetches only the start date, end date and an on/off flag for each seasonal event the app already contains. Later versions also fetch on/off switches for individual features (Adventure, iCloud sync, visual effects), for each ad placement and for the tracking prompt, and a few numbers such as how many ad-rewarded undos a run offers and how often an interstitial may appear, all within limits built into the app. This lets us move or stop an event, or turn off something that misbehaves, without an update. It cannot add content, cannot turn on anything the app ships switched off, and never takes away anything you have earned or bought. The request carries the Firebase installation identifier described above and no gameplay data, and it is configuration rather than measurement, so it is not covered by the analytics consent choice and happens whether or not you consented to measurement. Nothing about you is sent or stored by it. Without a connection the app uses the last values it received, or its built-in ones.
Advertising (Google AdMob)
Lineburst shows these ads, all served by Google AdMob:
- optional rewarded videos you choose to watch: to continue a run or an Adventure level, to undo a move, or to get new pieces when one doesn't fit;
- interstitials (full-screen ads) at natural breaks: after you finish a run and choose New Run or Home, and after you complete an Adventure level. They never appear during play, never over the continue offer, and not within a few minutes of another full-screen ad;
- a banner at the bottom of the game screen, never on menus.
If you purchase Premium, the app shows no ads of any kind and never requests one.
Personalized ads and tracking. On first launch the app asks, through Apple's App Tracking Transparency prompt, whether it may track you. If you allow it, Google may use your device's advertising identifier to show ads that are more relevant to you and to measure them, which Apple defines as tracking. If you ask the app not to track, ads are non-personalized and the advertising identifier is not available. You can change your answer at any time in iOS Settings → Privacy & Security → Tracking. In the European Economic Area and the United Kingdom, the consent dialog decides as well; you can change it from the same dialog.
To serve, measure and secure ads, Google processes technical data such as your IP address (which implies a coarse location), device identifiers, ad interaction data, and diagnostic information. The app itself never links this data to you: we have no accounts and no identifier of our own.
How Google uses this data is described at:
In the European Economic Area and the United Kingdom, a consent dialog may appear before ads are served, as required by law.
Purchases
The optional Premium purchase is processed entirely by Apple through your Apple Account. We never see your payment details. Purchases can be restored from Settings → Restore Purchases.
Game Center
If you are signed in to Apple's Game Center, your scores and achievement progress are submitted to the Lineburst leaderboards through Apple's service under Apple's privacy terms. If you are not signed in, nothing is submitted anywhere.
Children
Lineburst is a general-audience app. It contains no chat and no user-generated content. Ads are personalized only for players who allow tracking.
Changes
If this policy changes, the updated version will be posted at this address with a new effective date.
