Hmm no, I use this from time to time, and it really is just a way to copy the codes to another device. It won't delete them from the original device. It notifies the device owner after a few minutes that the TOTP have been exported, and it keeps a log of exports.
I'm in the process of moving to Aegis. It's FOSS, encrypts the file on the device, and supports the biometric lock. It can do a daily backup to a few sources, including the Google backup (I think) and personally I dump it to a folder that my Nexcloud will automatically upload to my personal server.
