Summary
This extension does not collect, store, or sell any personal data. It has no servers of its own. It does not track you. The only data it "transmits" is your CURP, RFC, or passport number — directly to the official CRT portals in Mexico, which are the legitimate destination of that query.

Where is it sent?

Never to Six-Seven servers or third parties.
Where is it stored?

In the browser's local storage (chrome.storage.local), encrypted by the browser itself.
For how long?

Maximum 24 hours. Automatically deleted after that.
