The Short Version
Social Auto Logout is a browser extension that automatically logs you out of Facebook and Instagram when you close your browser. This privacy policy explains exactly what data the extension accesses, what it does with it, and what it absolutely does not do.
The core principle is simple: everything happens locally on your device. No servers, no analytics, no accounts, no data collection of any kind.
This extension does not collect, transmit, sell, or share any of your personal data. It only reads and deletes browser cookies — on your machine, for your benefit.
Data Stored Locally
The extension stores a small amount of data in your browser's local storage to remember your preferences and display useful information in the popup. This data never leaves your device.
| Item | What It Is | Where Stored | Transmitted? |
|---|---|---|---|
| Settings | Your toggle preferences (FB on/off, IG on/off, etc.) | chrome.storage.sync | Never |
| Last Logout | Timestamp and result of the most recent logout action | chrome.storage.local | Never |
| Pending Flag | A temporary flag set during browser close to handle crash recovery | chrome.storage.local | Never |
Note: chrome.storage.sync may sync your settings across devices via your signed-in Chrome/Brave account — but this is controlled entirely by your browser, not by us. The synced data is only your extension preferences (which sites to auto-logout), not any browsing history or session data.
We Never Touch This
To be completely explicit, the extension does not collect, read, store, or transmit any of the following:
- Your Facebook or Instagram username, password, or account details
- The content of any web pages you visit
- Your browsing history or search queries
- The values or content of any cookies (only their existence is checked)
- Your IP address or location
- Device identifiers or hardware information
- Any personally identifiable information whatsoever
- Analytics, crash reports, or usage statistics
There is no backend server. There is no telemetry. There is no way for the extension author to see anything you do.
Why Each Permission Is Needed
The extension requests the following browser permissions. Here's exactly why each is necessary:
| Permission | Why It's Required |
|---|---|
cookies |
To read and delete session cookies for Facebook and Instagram during logout. |
tabs |
To detect when all browser windows are closed (the trigger for auto-logout). |
storage |
To save your settings and last-logout timestamp locally in your browser. |
alarms |
Reserved for potential scheduled logout features; currently unused. |
| Host: facebook.com | Required to access and clear cookies on the Facebook domain. |
| Host: instagram.com | Required to access and clear cookies on the Instagram domain. |
The extension only accesses cookies for facebook.com and instagram.com. It does not access cookies for any other website.
The Technical Process
When your last browser window closes, the extension's background service worker:
- Detects that no browser windows remain open
- Reads your saved settings to determine which sites to log out of
- Calls
chrome.cookies.getAll()for the specified domains - Calls
chrome.cookies.remove()on each session cookie - Records the timestamp of the logout in local storage
This entire process runs locally inside your browser. The cookie values are never read by the extension — only their names are used to identify which ones to delete.
On browser restart, if a crash occurred before logout could complete, the extension detects a pending logout flag and clears cookies before you start a new session.
Third-Party Sharing
We do not share data with any third parties because we do not collect any data to share.
The extension has no dependencies on any external libraries, analytics platforms, CDNs, or remote services. All code runs entirely within your browser sandbox.
This extension is not affiliated with, endorsed by, or in any way associated with Meta Platforms, Inc. (Facebook / Instagram), Google, Brave Software, or any other company.
Children Under 13
This extension does not target children and does not knowingly collect any information from anyone, including children under 13 years of age. Since no data is collected from any user, there is no risk of inadvertently collecting information from minors.
Updates to This Policy
If this privacy policy is updated, the new version will be published at this URL with an updated effective date at the top. Continued use of the extension after a change constitutes acceptance of the updated policy.
Given that the extension collects no personal data by design, we do not anticipate any material changes to this policy.
