Privacy Policy

Last updated: 6 May 2026

Roundo (“the app”) is a free, ad-free interval and CrossFit-style workout timer for Android and Wear OS, published by Tomáš Hulek.

This policy explains what data the app handles. The short version: the app collects nothing, sends nothing, and contains no third-party tracking, no analytics, and no advertising SDKs.

Data we collect

None. Roundo does not collect, transmit, or share any personal or non-personal data with the developer or any third party.

The app does not require an account, does not use network requests for its core functionality, and contains no analytics, crash reporting, or advertising frameworks.

Data stored on your device

Roundo stores the following data locally on your device only, using Android’s standard Preferences DataStore. This data never leaves the device and is removed when you uninstall the app:

Your audio mute preference.
The last timer mode you used (so the home screen can highlight it).
Your last-used timer configuration per mode (rounds, durations, etc.) so the setup screen can pre-fill it next time.
Saved timer presets you create.
Theme and language preferences.

If you have Android Auto Backup enabled, this data may be included in your device’s encrypted backup to your own Google account, governed by Google’s backup terms. The developer has no access to those backups.

Permissions

Roundo requests only the minimum permissions needed for a workout timer to function:

Foreground service — to keep your timer running accurately while the screen is off or the app is in the background. No data is transmitted.
Vibration — to deliver haptic feedback for phase transitions.
Wake lock (implicit, via foreground service) — to prevent the timer from being paused by the system mid-workout.

The app does not request access to the network, location, contacts, microphone, camera, files, or any other sensitive resource.

External links

Roundo’s settings screen contains a link to a donation page (Buy Me a Coffee / Ko-fi). Tapping it opens your default browser. The linked services have their own privacy policies, which the developer does not control. Donations are entirely optional and unlock no app features.

Children

Roundo does not knowingly collect any data from anyone, including children.

Changes to this policy

If this policy is updated, the new version will be published at the same URL with a new “Last updated” date.
