Privacy Policy

Effective July 17, 2026

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 owned by that Google account and to read, create, and update events on an owned calendar selected by that person.

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, advertising identifiers, or write access to calendars the signed-in person does not own.

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 has no analytics service, advertising service, shared family database, or data broker integration, and does not sell personal information.

Retention and deletion

Security and children

TaskScience requests only the narrow Calendar scopes needed for its stated behavior and uses stable identifiers to avoid duplicate writes. It is a general productivity tool and is not directed to children under 13.
