Android Fediverse client that does not send user agent to servers (programming.dev)

Hi everyone,

I’m looking for recommendations for an Android Fediverse client that does not send user-agent information (device or client details) to servers. Ideally, it should support both Mastodon and Lemmy, or other Fediverse platforms as well.

What do you mean by "device or client details"? If you want to log in, it will have to send your credentials

As for fingerprinting, does any of the open source clients do that?

What do you mean by “device or client details”?

It means information like device type and which client I am using (voyager ...)

AFAIK the apps are rather based on the APIs. And in general APIs usually don't require a User-Agent header as they return only data, without the html

Do you know of an app that is setting user agent?

I guess, pick one that you like and check (check code or network traffic) if it's setting user-agent header

I just checked, they do send user agent to lemmy server.

For example

    final appVersion = getCurrentVersion(removeInternalBuildNumber: true, trimV: true);
    return {
      'User-Agent': 'Thunder/$appVersion',
      'Content-Type': 'application/json',
      'Accept': 'application/json',
      if (account.jwt != null) 'Authorization': 'Bearer ${account.jwt}',
