Privacy Policy

Effective October 19, 2026

This policy explains what information the CtrlWin Android app ("CtrlWin", "the app") collects, how it's used, and the choices you have. In this policy, "we" and "us" mean the developer of CtrlWin. If you have questions, email us at support@ctrlwin.app.

The short version: CtrlWin doesn't ask you to sign in and doesn't collect your name, email, contacts, files, photos, or precise location. Your controller input and keystrokes go only from your phone to your own PC over Bluetooth; we never receive them. We use Google Analytics for Firebase to count anonymous app usage, such as which screens are opened, with advertising features turned off.

Information that stays on your phone

If you've turned on Android backup, Android may include the app's profiles and settings in your phone's backup to your Google account. That backup is controlled by Android and your Google account settings; we can't access it.

Information collected for analytics

CtrlWin uses Google Analytics for Firebase, a service provided by Google LLC, to understand how the app is used so we can improve it, for example to see which setup steps people find hard. Analytics collects:

DataExamples
App activityScreens opened (for example, the Play, Edit, and setup guide screens), first open, sessions, and app updates
App instance IDA random identifier Analytics creates for each installation of the app. It isn't linked to your name or account, and it changes if you reinstall the app.
Device and app informationPhone model, Android version, app version, language, and screen size
Approximate locationCountry or region, which Google derives from your IP address. Analytics doesn't store your IP address or your precise location.

We've configured Analytics so that it doesn't collect your device's advertising ID and doesn't use data for ad personalization at this time, but it may in the future. Analytics data doesn't include your mappings, the keys you send, or anything you type.

Data is encrypted in transit. Google processes it on our behalf under the Firebase data processing terms; see Google's Privacy Policy and how Google Analytics for Firebase collects data. Event data is kept for the retention period set in our Analytics account, which is never longer than 14 months, and then deleted automatically.

Permissions the app uses

Google Play

CtrlWin uses Google Play's in-app update service to tell you when a newer version is available. Google Play handles that check under Google's Privacy Policy; we don't receive any information from it. Downloads, purchases, and reviews in the Play Store are also handled by Google.

How we share information

We don't sell your information, and we don't share it with anyone except Google, as described above, to provide analytics. We may disclose information if required by law.

Your choices and rights

Our legal basis for analytics, where the GDPR applies, is our legitimate interest in understanding and improving the app.

Children

CtrlWin isn't directed at children under 13 and doesn't knowingly collect personal information from them. If you believe a child has provided personal information, contact us and we'll delete it.

Security

Analytics data is sent over encrypted connections. The Bluetooth link to your PC uses Bluetooth pairing and encryption. No method of transmission or storage is completely secure, but we work to protect the information we handle.

International transfers

Google may process analytics data in the United States and other countries where it operates, under the safeguards described in its data processing terms.

Changes to this policy

If we change this policy, we'll post the new version on this page and update the effective date. If a change is significant, we'll also tell you in the app or on the Play Store listing.

Email support@ctrlwin.app with any questions about this policy or your data.
