Privacy Policy
Timebox Mark stores only the data needed to run your timeboxed plan, sync it after sign-in, and export selected blocks to your calendar.
Data We Store
The app may store brain dump items, reminders, top priorities, timebox titles and time ranges, completed timebox count, notification preferences, and sound preferences.
When you are signed in, this daily plan data may be stored in Firebase Firestore under your account. When cloud sync is unavailable, the app keeps planning data on your device.
Account Data
If you sign in with Apple or Google, Timebox Mark receives basic account information such as a user identifier, email address, and display name when the provider supplies it. This is used for authentication, plan sync, and calendar provider connection.
Notifications
Timebox Mark uses local notifications to alert you when a focus block or break ends. The current build does not use a remote push notification server.
Live Activity
On iOS, Timebox Mark uses Live Activity to display the active timer, visible top priorities, and current timebox on the Lock Screen and Dynamic Island.
Calendar Access
Calendar export is optional. Apple Calendar permission is requested only when you choose to export time boxes. On supported iOS versions, the app requests write-only access so it can create events without reading your existing calendar data.
Google Calendar permission is requested only to create the events you choose to export. Google Calendar data is not sold, used for advertising, or shared with unrelated third parties.
Google User Data
The app's use and transfer of information received from Google APIs adheres to the Google API Services User Data Policy, including the Limited Use requirements.
Data We Do Not Collect
Timebox Mark does not collect location, contacts, photos, browsing history, or advertising identifiers, and it does not track you across apps or websites.
Account Deletion
You can start account deletion inside the app from Settings. Account deletion removes your Firebase account and synced Timebox Mark plan data associated with that account.
You can also request deletion by email if you cannot access the app. Include the email address used to sign in so the account can be located.
