Threema is a nightmare, if you switch from iOS to Android or vice-versa there is literally no way to migrate your data, and this fact is extremely obfuscated by the help docs which mention "export" but surprise! There's no importer. Its push notifications are extremely annoying as well, either just not working at all, or notifying for every message in a huge group. Use Signal instead.

As already mentioned in another comment, since December there's a new cross-platform server based backup that will allow you to transfer your ID, settings, contacts and groups to other devices: https://threema.ch/en/blog/posts/threema-safe-en The design is documented in the crypto whitepaper: https://threema.ch/press-files/2_documentation/cryptography_... You can also host your own backup server.

The iOS integration is still in Beta, but will be released soon. Windows Phone will also support this.

But no actual content. Normal people don't care about this nonsense, they just want to talk to their friends, and I get to explain to them why the only way they can read their old messages is via a zip file full of TXT documents.

People that don't care about this just use WhatsApp, Facebook Messenger, etc. They are well served, so not sure what exactly are you complaining about.

They don't though. They get lured in by news of the "NSA spying on them", install this app, and later find out all of the caveats after they're committed and end up losing data. It sucks.

At least Threema allows manually backing up and restoring the data on the same platform. Signal doesn't even allow backing up your conversations on iOS. Signal is coded to actively block backing up the data to iTunes or iCloud! Your chats are all gone the moment you move to a newer device (be it Android or iOS). If keeping conversations over time and having continuity is important, Signal is the last platform in this world you should be looking at.

Even Wire doesn't allow cross platform data backup and restore.

That's Unfortunate, on Android you can restore your messages in Signal
