So you don't store numbers of any of your contacts? You must have some insane memory ... but then again ... maybe memorizing random people's data should also be illegal... I mean did the people who told you those details give you permission to memorize it? I think not. And when you enter those memorized details into your browser or phone ... who gave you permission to do that?! Blatant GDPR violations.

If only there was some way to store contacts without uploading them..

Has it really come to this? If you open your phone now you usually have two offline options: to store contacts on the SIM card and to store them on the phone.

If you want backups and comfort without betraying your contacts you run your own nextcloud instance and store them automatically on there.
