# Privacy Policy
**Last updated: May 24, 2026**
This Privacy Policy describes how "Language Switcher Widget" (referred to as "the App") handles your information. By using the App, you agree to the collection and use of information in accordance with this policy.
## 1. Information Collection and Use
The App is designed to help users quickly switch system languages via a home screen widget. To improve the user experience and ensure stability, we use third-party services that may collect certain information.
### 1.1 Analytics
We use **Firebase Analytics** (Google Analytics for Firebase) to understand how the App is used. This includes:
* **Usage Data**: Events such as when the widget is added to the home screen.
* **Device Information**: Technical data such as device model, OS version, and system locale settings.
* **Identifiers**: Anonymous identifiers that help us track unique users without identifying them personally.
### 1.2 Crash Reporting
We use **Firebase Crashlytics** to monitor and fix technical issues. When the App crashes or encounters a non-fatal error, it sends a report containing:
* Stack traces and error messages.
* Device state (e.g., battery level, proximity to a crash).
* Device model and OS version.
## 2. Permissions
The App requires specific permissions to function:
* **Write System Settings / Change Configuration**: Required to change the device's system language (locale) as requested by the user.
* **Internet & Network State**: Required to send anonymous analytics and crash reports to Firebase.
## 3. Third-Party Services
The App uses third-party services that have their own Privacy Policies:
* [Google Play Services](https://www.google.com/policies/privacy/)
* [Firebase Analytics](https://firebase.google.com/support/privacy)
* [Firebase Crashlytics](https://firebase.google.com/support/privacy)
## 4. Data Retention
We do not collect or store any personal data (such as names, email addresses, or precise location) on our own servers. Analytics and crash data are retained by Google/Firebase according to their standard retention policies.
## 5. Children's Privacy
The App does not address anyone under the age of 13. We do not knowingly collect personally identifiable information from children under 13.
## 6. Changes to This Privacy Policy
We may update our Privacy Policy from time to time. You are advised to review this page periodically for any changes.
