Red Button Timer — Privacy Policy

Last updated: 10 November 2026

Red Button Timer (“the app”) is developed by Dmitry Chulkin, Haifa, Israel. Contact: dimachulkin@gmail.com.

Personal data

The app does not collect, store on any server, sell or share personal data. It has no accounts, no analytics, no tracking and no third-party advertising networks.

Data kept on your device

• Timer settings: duration, sound on/off, the chosen alarm sound, screen flashing on/off, focus mode on/off.
• If you choose your own alarm sound, the app gets read access to that one file through the Android file picker and only plays it on your device.
• If you record your own alarm sound, the recording is saved only inside the app on your device and is played only there. It is never uploaded and is deleted when you uninstall the app.

These settings never leave your device and are deleted when you uninstall the app.

Internet

About once a day, when you open the app, it downloads a small public text file (ki-aikido-israel.com/redbutton/ad.json) with the text of the advertising line. The request contains no personal data or identifiers. As with any web request, your IP address reaches the website’s hosting provider and may appear in its technical logs; the developer does not use them to identify anyone. To show ads meant for your area, the hosting provider estimates your country and city from your IP address while answering the request; this estimate is not stored or passed to the developer or to advertisers.

Advertising line

The line at the top of the screen shows text chosen by the developer. Tapping it opens the advertiser’s website or an e-mail draft — only when you tap. Nothing about you is sent to advertisers.

Permissions

• Vibration, notifications, exact alarms, full-screen notifications — to ring on time and show STOP over the lock screen.
• Internet — only for the advertising line described above.
• Microphone — only while you record your own alarm sound, and only after you allow it.
• Do Not Disturb access — only if you turn on focus mode: while the timer runs, notifications are silenced (calls and alarms still come through), and your previous Do Not Disturb settings are restored afterwards.

Children

The app is not directed at children under 13 and collects no data from anyone.

Changes

If this policy changes, the new version will be published on this page with a new date.
