CaseLens reads immigration case data from my.uscis.gov using the browser's existing signed-in session, displays it in a panel on that page, and stores it in that browser.

Data handled: personally identifiable information that USCIS returns about the signed-in account — name, mailing address, receipt numbers, document identifiers, case status text and event history — and page content from my.uscis.gov, which is read to discover the receipt numbers already printed on the account page.

Where it is stored: localStorage on the my.uscis.gov origin, on the device, under keys prefixed "uscisTracker.".

Where it is sent: nowhere. CaseLens has no server, no account system, no analytics, no telemetry, no crash reporting and no advertising. It makes no network request other than read-only GET requests to my.uscis.gov, the site the user is already signed in to. Every URL it can construct is built from a single ENDPOINTS map in the source.

Who it is shared with: no one. Nothing is sold, transferred or disclosed to any third party. There is no third party.

Data the user moves themselves: two features write data out of the panel, and both require a deliberate action. Export downloads a JSON backup to the device, which contains full receipt numbers even when "Hide receipt numbers" is on, because a masked backup could not restore anything. Copy summary places case text on the clipboard. Where those files then go is outside CaseLens's control.

Retention and deletion: stored data persists until deleted. Settings > "Erase everything" removes all of it from that browser. Uninstalling the extension does not clear it, because the data belongs to the my.uscis.gov origin rather than to the extension; to remove it after uninstalling, clear site data for my.uscis.gov. Anything stored is visible to anyone using the same browser profile, and there is no password on the panel.
