Idea : a sync app for our fediverse accounts

Hi,

I want to suggest a concept to solve the issue losing our data when an instance shut down. Maybe it already exist.

Problem

When an instance shutdown, you have no way to recovert your account and export your blocklist, subcription...It is too late and lost. You have to start it again, who prepared a backup ? Almost no one because its design was flawed.

Idea

The only solution would be nomadic identity.

I think we, the fediverse, can create a sync app on our computer. Here is the concept :

• flatpak for linux distro agnostic
• fediapp agnostic. we want to support every free software fedi app.

We install it on our computer. Then click on a plus button to add our fedi accounts.

It will ask for 2-3 fields :

• username
• password
• generated-token (not sure if it is useful, security ?)

Then it will sync on our local computer : blocklist, followers, subscription, setting... maybe encrypted for increased security

Later, we can imagine other features as :

• master account
• merging blocklist, subcription between selected account
• exporting posts, comments...
• managing account settings
• mobile app
• support of apple and windows

What do you think ? Can we achieve that ?
