Privacy Policy

Last updated: July 12, 2026

AI Deadline Dog ("the extension") finds dates and deadlines on webpages you visit and helps you add them to your calendar.

The extension does not collect, transmit, store remotely, or share any data.

Data collection

All webpage analysis (date detection and classification) runs locally in your browser. Page content never leaves your device.
The extension makes no network requests to any server operated by us or by third parties. It contains no analytics, no telemetry, and no error reporting.
No account or sign-up exists.

Data stored locally

The following is stored only in your browser's extension storage (chrome.storage.local) and never transmitted:

Your preferences (language, dark mode, highlight and mascot settings, per-site dark-theme choices).
Deadlines you choose to track for the countdown badge (title, date, time zone, and the address of the page they came from).

Uninstalling the extension deletes all of this data.

Calendar integration

Google Calendar: "Add to Google Calendar" opens a standard calendar.google.com tab prefilled with the event you reviewed. This is a normal page navigation in your own browser session; the extension has no access to your Google account, calendar, or credentials.
.ics download: calendar files are generated locally and saved through your browser's regular download mechanism.

Permissions

Permission	Purpose
`storage`	Save your preferences and tracked deadlines on your device
`sidePanel`	Show the review panel UI
`activeTab` / `scripting`	Read the page you are viewing to detect dates on it, when you invoke the extension
`alarms`	Refresh the countdown badge hourly so the day count stays accurate

Changes

If this policy ever changes (for example, if a future version adds an optional online feature), the change will be described in the extension's changelog and on this page before release.
