Swiftgram uses official Apple DeviceCheck tokens to ensure requests are coming from the Swiftgram app and not abused by other devs like Nekogram did. Swiftgram generates new token on each request. Since tokens are single-use and ephemeral, Apple makes it impossible to fingerprint devices by design.
App will cache registration date data. In the mean time it's 12 hours. So no requests will be made in the next 12 hours for the profiles you've already seen.
The same DeviceCheck token is used in another request - validating purchases of Swiftgram Pro.

Any server will know the IP of your device and can potentially match requests by the IP address - this is how internet works. So there's no need to go through hoops of user payload, device tokens, etc to create another ⚡️exclusive reveal post.

I admit it might be redundant to pass the payload for this request, but that's some basic authorization - an additional API protection measure, so I see no harm there. It was working in a similar way since I've first introduced it in Nicegram in 2019.
Swiftgram server does not store IP addresses, Registration Date requests and does not link any users or devices together. That's an enormous amount of data for ~400k MAU app with no value at all.

If you're paranoid, you can simply disable Registration Date and no requests will be made.
If you're paranoid enough, you can build the app yourself from source code (which you didn't even bother to check) and modify it the way you feel safer.
