Google office stuff > libreoffice
Chrome > firefox and librewolf
gmail > proton
Google > ddg
Iphone > grapheneos pixel
Youtube account > newpipe, libretube, grayjay with exported subscriptions
Google drive > synology
I think that covers about everything google specific.
Note: I included iphone because even iphones ping google SUPL servers whereas Grapheneos settings host their own servers to ping to avoid sending stuff out to google.
I know there are more options out there but what I have is a synology nas.
I self host the nas at home and I can still access the photos and stuff everywhere I go.
I chose synology because even though its proprietary and a little overpriced, at the time, I was short on time to learn the inner workings of free operating systems and setting up all the certificates, ddns, ports, etc.
Ofc there are also other cloud providers as well, but I use the synology for jellyfin so I killed 2 birds with one stone.
