So other instances outside the instance your user exist on, has access to this? Which means everyone, as anyone can create an instance?

Could an instance be hosted inside an app? In a container locally on your own machine? Maybe the two could be synced? One instance across all your devices synced?

That would be the safest?

It could be different since it’s decentralized

It also feels faster when loading, though slower when you enter a post or save a comment.
