Encryption

If you only sync your devices locally, you can do without encryption, especially since it can be enabled retroactively. Depending on the data volume, however, the first encryption can take a long time. For this reason, it makes sense to use the encryption function right from the start regardless of which devices you plan to sync or whether you sync at all.

When setting up encryption, Joplin generates a password-protected master key. The password must be entered on each device that you include in the synchronization setup. Keep the password in a safe place, because if it's lost, you won't be able to access your notes.

If you are retroactively enabling encryption, the Joplin developers recommend doing this on the device with the highest computing power. Joplin then encrypts the content, and all devices involved are updated by synchronization. Only enable encryption on the other devices after they have received the master key via synchronization. Otherwise you will have several master keys with several passwords – not a technical problem, but a major organizational headache.

Conclusions

Joplin is unlikely to win a beauty contest. Additionally, if you are already pushing Evernote's limits, you will probably not be totally satisfied with its free competitor. However, for most users, Joplin covers all your daily needs and, as a massive benefit, offers you full control over your own data. The program can even import Evernote data, so there is nothing standing in the way of a change.
