Use the sync feature. Note data is encrypted with the AES algorithm before being stored on the sync server. You will also need to remember the secret key if you want to read your notes.
Will my data ever be lost?
Data is stored in the persistent memory of the browser you use to install OpenNotas. Therefore, data is only lost when you clear the cache or uninstall the OpenNotas app or the browser. I recommend you use the sync feature or back up your data regularly to avoid unfortunate situations.
