Nevö creates a Firebase identity for each device (including anonymous sign-in). That identity is treated as your Nevö account for this device.
When the request succeeds, Nevö deletes cloud data for this device, clears local profile data for this session, and removes the Firebase identity so the app returns to setup.
If you cannot use the in-app path, email tuki@righthere.fi with subject “Nevö account deletion request” and include:
Because sign-in is anonymous, the recovery code is the best way to locate matching records. We handle email requests without undue delay and normally within 30 days when we can identify the relevant data.
We may retain limited security or provider logs until they expire (typically up to 30 days), and information we are legally required to keep. Local reminder history on other household devices may remain until those users delete them.
Removing a single connection or stopping reminders is not the same as deleting your account and all related cloud data.
