Why not ofload that shit to some relay?

Relays get wiped. Data loss risk.

Plus, a relay is just a shitty server. You don’t want that if you for some reason take off.

Sending that type of data to a relay only makes sense if you want to share it with others in some way (like a competition) or it's your own relay. Otherwise it's hardly better than just backing it up locally or to your own cloud storage. I ran into this recently for an app idea I had. It occurred to me that I didn't want anyone to see the data, so why fuck with encryption and relays?
