Best Google Photos alternative?
Your photos are very important memories that shouldn't have to be scanned and sold by evil Google.
I would highly recommend using Stingle Photos instead. Very user friendly and they offer a free plan. (1GB)
Personally, I have been using Stingle Photos for years now and it is by far the #1 alternative in my opinion. (Android and iOS only)
If possible, I would recommend self hosting/keeping all of your files safe yourself and not relying on a server to keep them safe, because you never know when small human error or a snap could cause you to lose everything.
