Interval Timer – HIIT & Tabata Workout Timer
Summary
Interval Timer – HIIT & Tabata Workout Timer does not collect, sell, rent, or share your personal information. There is no account, no sign-in, and no analytics or advertising SDK of any kind built into this extension. Data you create while using the extension — such as entries, notes, settings or history — is stored locally in your own browser using the browser's built-in extension storage, and stays on your device unless you explicitly export it yourself.
What data is stored, and where
All data the extension needs to function is saved locally, on your device, using your browser's Extension Storage API (and, for some extensions, IndexedDB for larger files). This data is:
- Never transmitted to ABCMuscle or to any third party
- Never used for advertising or analytics
- Removed automatically if you uninstall the extension or clear your browser's extension data
Permissions this extension requests, and why
- storage (Required) — Save your data (settings, entries, history) locally in your browser using the standard Extension Storage API.
- sidePanel (Required) — Display the extension in the browser's side panel.
- notifications (Optional — off until you turn it on) — Show a system notification for a reminder, alarm or timer you've set. Requested only when you turn a notification-based feature on.
How this extension behaves
The optional Notifications permission is used only for local countdown alerts during a workout.
Third-party services
This extension does not connect to any server operated by ABCMuscle or any third-party analytics, advertising, or tracking service.
Children's privacy
This extension is not directed at children and does not knowingly collect information from anyone. Because no data is collected in the first place, there is no personal information of any user, including children, retained by ABCMuscle.
Data retention and deletion
Since all data stays in your browser's local storage, you control it directly: clear it from the extension's own Settings/Export screen (where offered), or remove it entirely by uninstalling the extension. ABCMuscle has no copy of your data to retain or delete, because none is ever sent to us.
Changes to this policy
If this policy changes, the "Last updated" date above will change accordingly. Continued use of the extension after an update constitutes acceptance of the revised policy.
