Taskbook privacy policy

Last updated: November 7, 2026

Taskbook is a personal, single-user task management application implemented as a Google spreadsheet with an associated Google Apps Script. It is not offered to the public as a hosted service.

Data accessed

The script reads task, project, list, note, scheduling, settings, and change-history information from the owner's Taskbook spreadsheet. Its Google OAuth permissions allow spreadsheet access, adding a spreadsheet menu, and installing or managing Apps Script triggers.

How the data is used

The data is used to render the Dashboard and subject views, process the owner's edits, track changes and activity within the spreadsheet, and synchronize those views using edit and scheduled executions. Script properties also retain operational settings such as view hashes and trigger configuration.

Storage and sharing

Taskbook's task data and its audit history remain in the owner's Google spreadsheet. Operational properties remain in Google Apps Script. The Taskbook script does not send spreadsheet data to an outside server, sell it, use it for advertising, or share it with other users. Google's services process information as necessary to operate Sheets and Apps Script.

Retention and control

The spreadsheet owner controls the contents and retention of task data. The owner can change or delete information in the spreadsheet, remove the script, or revoke the app's Google account permissions. Removing authorization prevents further authorized script access but does not itself delete existing spreadsheet content.

Changes
