RoundBellTimer does not collect, transmit, or share any personal information.
RoundBellTimer is an offline interval timer for rounds, circuits and Tabata with the common protocols already set up. The pages that follow describe, in plain language, what the app does and does not do with the things you type into it.
None. There is no account, no sign-up and no login in RoundBellTimer. The app never asks for your name, email address, phone number or any other identifier, and it has no way of sending one to us even if you typed it in. Any text you enter, such as a workout name, a custom plan label or an athlete display name, stays on your device.
For the app to work, the following is kept in the operating system's local storage, on your phone, and nowhere else:
All of it lives in a local Hive database inside the app's own private storage directory on your device, sandboxed by the operating system so other apps cannot read it.
None of it is uploaded. Uninstalling the app removes every byte.
RoundBellTimer requests no runtime permissions. The Android manifest declares none of the sensitive permissions, so there is no camera, location, microphone, contacts, photo or notification access, and the iOS build declares no usage descriptions, because the app needs none of them to run a timer.
The app is fully offline. Every preset and protocol ships inside the installed app. There is no server behind RoundBellTimer, no endpoint it contacts, no content it downloads and no usage data it uploads. It runs identically in flight mode. If you use the share button to send a workout summary, it goes to whichever app you pick in the system share sheet, and that app's privacy policy then covers it. Nothing leaves the app unless you tap share.
No third-party SDKs are integrated. There is no analytics library, no advertising network, no crash reporter and no attribution or A/B-testing service in this app. The only external packages it uses are open-source Flutter UI and local-storage libraries that run entirely on your device and send nothing anywhere.
The app is suitable for all ages and is not directed at children under 13 in particular. That said, the question of children's data barely arises here: RoundBellTimer collects no personal information from anyone, of any age, and transmits nothing off the device. There is no profile to build, no advertising identifier, no behavioural tracking and no content that a child could send to us or to a third party. We therefore do not knowingly collect personal information from children under 13 (COPPA) or under 16 (GDPR-K), because we do not collect personal information from any user at all.
Everything the app knows about you is already on your device and under your control. You can delete individual sessions and custom plans in the app, or clear the app's storage from the system settings. Uninstalling RoundBellTimer removes the Hive database and every workout, plan, badge and preference with it. We keep no copy on any server, so there is nothing for us to return, correct or erase on request.
If anything in this policy changes, the date at the top of the page will be revised, and material changes will appear in the app's release notes.
