Taskbook
Taskbook is a personal task and project management application built around a Google spreadsheet and its associated Google Apps Script.
The application organizes tasks, projects, and ongoing lists. It draws a dashboard and subject views from information held in the spreadsheet, synchronizes edits made in those views, and keeps the views up to date using Google Apps Script triggers.
Taskbook is maintained for private, single-user use. It is not a public service and does not offer user registration or an external login.
Google account access
Taskbook requests access to Google Sheets so that its Apps Script can read and update the owner's Taskbook spreadsheet. It also uses Apps Script permissions to display a spreadsheet menu and manage its edit and time-based triggers. Those permissions support the application's task synchronization and display functions.
Taskbook does not use this website to sign users in or to collect Google account data.
