Logging out handles the account layer. It does not automatically erase everything that still lives on the device layer.
That is why the first useful split is browser state versus account state, not simply 'logged in' versus 'logged out.'
See which layer the data lives in first
Logout mainly ends the session identity.
Autofill, screenshots, cache, and saved history can still sit on the device afterward.
Questions like "After You Log Out of AI Fortune Telling, What Can Still Stay on the Device" make more sense when you separate the account layer, the device layer, and the contact layer first.
How the common risks actually show up
A public computer can still remember your email or search traces after logout.
A phone can still keep chart screenshots even after the account session ends.
Reading the public rule, then checking local traces, then checking the support path is usually more useful than obsessing over one button alone.
Do not treat vague wording as safety
Logged out does not mean cleaned up.
Most practical leftovers are ordinary device traces, not mysterious hidden files.
Safety cannot live only in a feeling. It needs a clear account, device, record, and contact path.
A steadier handling order
- Log out first, then inspect the device layer.
- Clear autofill, history, screenshots, and saved items separately.
- Do not stop at logout on a shared device.
