Privacy tips for termux

Hi, i think its really interesting topic. I recently discorvwred that i can with few commands encrypt files (pgp/age) with termux, shred them etc. Maybe bit more work but without trust for additional 3rd party teams. Do you know some more really useful privacy tips which can be used in termux? I Heard it is discorvwred when there is need for something, but maybe we will Discover sth other way😅
