TaskScience is a personal time-tracking app that connects to a Google Calendar selected by the person using the app. Version one does not operate a TaskScience server and does not combine data between family members.
Google data TaskScience accesses
After a person chooses Continue with Google, TaskScience requests permission to list calendars available to that Google account and to read events from the agenda calendars that person selects. It creates and updates the person's canonical Actual records in their owned TaskScience Actual calendar. When the person selects a writable shared calendar as an agenda source, TaskScience can also create and update a named copy of their Actual on that shared calendar. It never writes to a read-only shared calendar.
TaskScience uses this access to show planned tasks, attach a stable task identity and color to them, and write actual stopwatch segments. It does not request Gmail, contacts, Drive files, location, or advertising identifiers.
Data stored on the phone
TaskScience stores the selected calendar reference, agenda cache, task identities, timer state, completed-session index, Calendar sync token, and pending Calendar writes in private local app storage. Raw Google OAuth access tokens are not written to TaskScience local storage.
Data sent or shared
Calendar requests go directly from the phone to Google Calendar. TaskScience can generate a data report from completed Actual events in the selected Calendar. The report remains on the phone unless the person chooses to copy, download, or share it. Choosing Share with AI opens Android's share sheet so the person can select an AI app or other destination; TaskScience does not send the report automatically or operate the receiving AI service.
TaskScience does not use an advertising service, maintain a shared-user database, integrate with data brokers, or sell personal information.
Retention and deletion
- Local data remains until app storage is cleared or TaskScience is uninstalled.
- Calendar events remain until the calendar owner edits or deletes them.
- Signing out does not delete events already written.
- Google access can be revoked from the person's Google Account security settings.
Security and children
TaskScience requests the Calendar scopes needed for its stated behavior. If you track a Planned event from a writable shared calendar, TaskScience keeps your personal Actual/history record and also publishes a named copy of that Actual to the shared calendar so its members can see the recorded time and notes. TaskScience does not write to read-only shared calendars and uses stable identifiers to avoid duplicate writes. It is a general productivity tool and is not directed to children under 13.
