Open Source Data Recovery for Android?

I was looking for the same thing when I accidentally deleted a video from Google Photos app a month back. I didn't find any opensource ones, so I ended up using one from the playstore. Tried a few and turned off wifi before opening them, because I was sure they were going to have a lot of ads and generally don't want anything uploaded without me knowing.

One app worked (I don't even remember the name), then deleted it right away.
