On mobile I indeed also had that issue once. However I made sure they can’t lock me out completely. The db is stored using the opensource sqlcipher, so one can open it and extract everything manually, if absolutely necessary. As long as they don’t change this, I am fine. In the worst case that would still be a lot of effort for me, but not impossible.

The export has also improved a lot. You can now also export to JSON which includes all the data one could need.
