Open Notepea on the destination device and import the backup file. Supply its password or key file when asked. Open the imported notes and check them before removing the original copy.
If you forget your password
A recovery code can help you unlock notes that are still in this browser. It cannot bring back deleted browser data. There is no account password reset, so keep your recovery codes and backups separately.
