View account and Premium testing

Your saved custom templates remain readable, reusable, exportable and deletable after a subscription ends. New or edited templates require a currently confirmed membership.

Your sign-ins and data

Findbest does not read or store provider passwords or login cookies. Your Findbest account is separate. Chats and files go to selected providers only when you deliberately send them. Their free limits, subscriptions and upload conditions still apply.

History and custom templates are encrypted on your Chrome profile. Lost passphrases cannot be recovered. Web connections do not report exact token counts; optional estimates are clearly labeled.

Provider connections are experimental. Tests with controlled interfaces do not yet replace full verification with real free and Premium accounts.
