Social Checker is a browser extension that shows the number of unread notifications and messages from your own Facebook, Instagram, Threads, X, LinkedIn and Pinterest accounts. This policy explains what the extension accesses and what it does with it.
Social Checker does not collect, sell or share your personal data. Everything it handles stays in your browser.
Whether you are signed in to Facebook, Instagram, Threads, X, LinkedIn or Pinterest (presence of the session cookie)
Why: To show "Not signed in" or your counts
Where it goes: Nowhere. It is checked locally and never stored
The CSRF token cookie of Instagram, X, LinkedIn and Pinterest
Why: Sent back only to the same site in a request header, as that site requires, so it accepts the extension's request for your counts
Where it goes: Only to the site that issued it
Unread notification and message counts
Why: To show the badge, popup and desktop alerts
Where it goes: Stored locally in chrome.storage.local
Your settings (enabled networks, check interval, alert preferences)
Why: To remember your choices
Where it goes: Stored in chrome.storage.sync (synced by Chrome between your own devices, if you use Chrome Sync)
The extension does not read or store message content, notification text, contacts, names, photos, browsing history or any other personal information.
The extension communicates only with facebook.com, instagram.com, threads.com, threads.net, x.com, linkedin.com and pinterest.com, using the session you already have in your browser, to retrieve your own unread counts. It does not contact any other server, and it includes no analytics, advertising or tracking code.
No data is sold, transferred or shared with third parties. The extension's developer receives no data from it.
Counts and settings are kept only on your device and are overwritten on every check. Uninstalling the extension deletes all of them.
The extension is not directed at children under 13.
If this policy changes, the updated version will be published at this URL with a new "Last updated" date.
