Tasks Stack: Privacy policy

Last updated: October 12, 2026

Tasks Stack is a Chrome extension that shows all of your Google Tasks™ lists at once in the Tasks side panel of Google Calendar™, and lets you manage them there. This policy explains what the extension handles and what it doesn't.

The short version

• Your tasks stay between your browser and Google. The extension never sends your data to its developer or to anyone else.
• No analytics, tracking, advertising, or data sales.
• No account or sign-in: it works with the Google session you already have in Google Calendar.

What the extension handles, and why

To show and change your tasks, the extension runs only on calendar.google.com and Google's Tasks panel inside it (tasks.google.com/embed). There it reads, inside your browser:

• Your task lists and tasks (titles, details, dates and times, completion, stars, subtasks, and the order of your lists), from the Tasks page Google loads in the panel, so it can display them.
• The session values on that page (a request token and your account's numeric ID) so that changes you make (adding, editing, completing, moving or deleting tasks and lists) are saved to your Google account, in the same way Google's own Tasks panel saves them.

All of this is used only to provide the extension's single purpose: managing your Google Tasks lists in Google Calendar. Requests that save your changes go only to Google's own servers (tasks.google.com), using your existing Google session.

What the extension stores

A few display preferences (which lists you've collapsed, whether the Completed section is open, and whether you're using the all-lists or one-list view) are kept in your browser's local storage for calendar.google.com. The extension doesn't store your tasks anywhere; it reads them from Google each time.

What the extension doesn't do

• It doesn't send your data to the developer, to analytics services, or to any third party.
• It doesn't read your Google Calendar events, email, browsing history, or any site other than the two above.
• It doesn't load or run code from anywhere outside the extension package.

Limited Use

The use of information received by Tasks Stack adheres to the Chrome Web Store User Data Policy, including the Limited Use requirements. Data is used only to provide and improve the extension's single purpose, is not transferred to anyone except Google as needed to save your changes, is not used for advertising, and is not read by humans.

Removing the extension

Uninstalling the extension removes it and stops all of the above. Your tasks remain in your Google account, unchanged. To clear the stored preferences, clear site data for calendar.google.com in Chrome's settings.
