I accidently deleted the app from my android phone. Is there any way to restore the entries I had made? I didn't have it synched with other devices.
No there isn't. Deleting the app also deletes the database, just like with any other app using an offline database
timo Thank you. If I had synched it with other devices, would the entries have been stored on those other devices? Do I need the pro version for that?
Yes, using the sync stores the data in your private Cloud Storage and can be recovered from there.
Cloud Sync is a Pro feature, correct.
