Is Tabs Outliner safe?

Medium risk

Tabs Outliner sends a SHA-1 hash of the Chrome profile email to FastSpring during purchase checkout.

When a user starts the license purchase flow, Tabs Outliner asks Chrome for the profile email, lowercases it, hashes it with SHA-1, and places that identifier in a FastSpring checkout URL. The stored finding shows this happens in an HTTP navigation to FastSpring, so the raw email is not sent but an email-derived identifier is transmitted during checkout.

Where it sends data
