Summary

AutoCrumb collects no data. There is no server. Everything runs locally in your browser.

What data does AutoCrumb access?

AutoCrumb accesses the following browser data solely to perform its core function (automatic cookie deletion):

• Cookies — to read and delete cookies for domains when their tabs are closed
• Tab URLs — to track which domains are currently open, so we know when to trigger cleanup
• Your whitelist/greylist rules — stored in Chrome's built-in sync storage so they follow you across devices
• Activity logs and statistics — stored locally on your machine

What data does AutoCrumb send externally?

None. AutoCrumb makes zero network requests. There is no server, no API, no analytics, no telemetry. Your browsing data never leaves your machine.

What data does AutoCrumb store?

All data is stored using Chrome's built-in storage APIs:

• chrome.storage.sync — Your whitelist/greylist rules and settings. Synced by Chrome across your devices (encrypted by Google).
• chrome.storage.local — Activity logs and cleanup statistics. Stays on your current device.
• chrome.storage.session — Temporary runtime state (which tabs are open). Cleared when you close Chrome.

Third-party services

AutoCrumb uses no third-party services, libraries, or analytics. The extension is fully self-contained.

Permissions explained

• cookies — Read and delete cookies (core functionality)
