Anonymous use remains available
You do not need to create an account for basic NourishNot use. If you choose to continue anonymously, your installation can still record and use history normally.
What protection adds
Protecting your history with Google links your NourishNot history to a protected account. This can help you reconnect to that history after reinstalling or when using another device.
Google protection is about continuity. It does not turn every basic feature into a login-only feature.
When history already exists
If NourishNot finds existing protected history while the current installation also has its own activity, the app may ask whether you want to restore or merge the histories. You can cancel the prompt without immediately replacing the current installation’s identity or data, then return to the choice later.
After a successful restore or merge, supported history is associated with the protected history and the installation can continue recording to it.
Signing out
Signing out disconnects the current protected session. It does not mean that the protected history itself has been deleted.
