Privacy Policy

Your Game Data Stays on Your Device

Every puzzle you play, every word you place, your scores, your history, and your in-progress games are stored locally on your device. None of this information is uploaded to our servers or shared with anyone else. If you uninstall the app, that data is deleted along with it and cannot be recovered.

Four-Letter Words does not ask for your name, email address, phone number, location, contacts, photos, or any other personal information, and it does not create an account for you.

Analytics, Crash Logging, and Performance

To understand how the app is being used and to keep it working well, Four-Letter Words uses Google's Firebase platform — specifically Firebase Analytics, Firebase Crashlytics, and Firebase Performance Monitoring. The information collected falls into three broad categories, described below. None of it includes the contents of your games or anything you typed into the app.

Analytics

We collect aggregate information about how people use the app — for example, which screens are visited and which actions are taken — so that we can decide what to build, fix, and improve. The data describes app usage in broad terms and is not used to identify you personally.

Crash Logging

When the app crashes or hits an unexpected error, a crash report is sent so that we can diagnose and fix the problem. These reports describe the technical state of the app at the moment of the crash — things like the type of error, the device model, and the version of the operating system.

Performance

We also collect basic performance information, such as how quickly the app starts and how responsive it feels during normal use. This helps us spot regressions and keep the app smooth across different devices. Performance measurements are technical in nature and are not tied to your identity.

How Google Handles This Data

Because Firebase is operated by Google, some information is processed on Google's servers and is subject to Google's Privacy Policy. In the course of providing these services, Google may collect and process identifiers that are not chosen by you, including:

• a Firebase installation ID, which is a random identifier generated for each install of the app and is used to attribute events, crashes, and performance traces to the same installation;
• general device and network information such as device model, operating system version, app version, coarse language and region, and the IP address of the connection used to send the report (IP addresses are processed by Google and not stored long-term in the analytics data we see).

On Android, Four-Letter Words removes the AD_ID permission from its manifest, so Firebase Analytics does not collect the device's advertising ID. Firebase Analytics on Android relies only on the Firebase installation ID described above.

On iOS, Four-Letter Words is configured so that Firebase does not collect the device's Identifier for Advertisers (IDFA) or its Identifier for Vendor (IDFV). Because we do not read the IDFA, the App Tracking Transparency permission prompt is not shown, and Firebase Analytics on iOS relies only on the Firebase installation ID described above. Crash and performance reports likewise use Firebase's own per-install identifiers rather than IDFA or IDFV.

Google uses this data to provide and improve the Firebase services, and may also use it for its own purposes as described in the Firebase data disclosure and Google's privacy documentation. You can limit how this information is used by Google by adjusting the advertising and diagnostics settings on your device.

Four-Letter Words itself does not use any of this information for advertising, and we do not sell it. We use it only to understand and improve the app.
