If I can piggyback with a question: Does anyone know how “Read” status for posts is stored and accessible on both softwares?
I know that it’s stored and it would be cool if it was private, but I’m guessing it can be collected and used.
This information exists wherever your account exists. It’s nonfederated data, similar to things like your email address, hashed password, and 2FA master key. No other instance has any need to know what notifications you’ve viewed, so they are never made privy to that information.
To clarify: federation is not like P2P where everyone gets a copy of everything. Federation only shares exactly what needs to be shared for the software to function. In the case of Lemmy, this boils down to the following data:
User profiles
Communities
Posts
Comments
Votes
Follows
Blocks
Private Messages
Some of you may be raising eyebrows at this list. Does this mean that anyone can see your votes & PMs at any time? No, not exactly. There’s two big things to keep in mind here:
When possible, the smallest possible amount of federation is used (e.g.: votes are only sent to the instance where the post/comment is, Blocks/PMs only get sent to the instance where the other user is, etc.)
Unless it’s something the website shows, only instance admins can view the data that gets federated with it. Your PMs may not be secure, but they’re not exactly out on Google either.
At worst, here’s what information can be captured by a random bad actor running their own evil instance:
Your username
Your public bio
Your home instance
Your moderated communities
Your moderation history
Your comment history
Your post history
Your votes specifically for posts/comments belonging to the bad instance
Your follows specifically for communities belonging to the bad instance
Your PMs specifically to users belonging to the bad instance
Your blocks specifically of users belonging to the bad instance
The majority of this information is already publicly searchable on your home instance’s website. Pretty much all of the scary stuff requires you to actually directly interact with the bad guy’s instance. If you’re about to vote or follow something sketchy, consider double-checking who runs the instance before you attach your name to it (that’s what the rainbow link is for).
You are not logged in. However you can subscribe from another Fediverse account, for example Lemmy or Mastodon. To do this, paste the following into the search field of your instance: [email protected]
No such thing. Ask away!

Rule 4- No self promotion or upvote-farming of any kind.
That’s it.
Rule 5- No baiting or sealioning or promoting an agenda.
Questions which, instead of being of an innocuous nature, are specifically intended (based on reports and in the opinion of our crack moderation team) to bait users into ideological wars on charged political topics will be removed and the authors warned - or banned - depending on severity.
Rule 6- Regarding META posts and joke questions.
Provided it is about the community itself, you may post non-question posts using the [META] tag on your post title.
On fridays, you are allowed to post meme and troll questions, on the condition that it’s in text format only, and conforms with our other rules. These posts MUST include the [NSQ Friday] tag in their title.
If you post a serious question on friday and are looking only for legitimate answers, then please include the [Serious] tag on your post. Irrelevant replies will then be removed by moderators.
Rule 7- You can't harass or disturb other members.
If you vocally harass or discriminate against any individual member, you will be removed.
Likewise, if you are a member, sympathiser or a resemblant of a movement that is known to largely hate, mock, discriminate against, and/or want to take lives of a group of people, and you were provably vocal about your hate, then you will be banned on sight.
Rule 8- All comments should try to stay relevant to their parent content. Rule 9- Reposts from other platforms are not allowed.
