They tout it being made 'local first' all data would then be stored locally so the user can access it offline. The 1 GB limitation is for paid backups which a user doesn't have to do. If I wanted a backup, I could just share p2p share from my laptop to my PC for example. Both would have copies.
The p2p relay is a way to coordinate p2p connections, data doesn't pass through them. Once a connection is made between my laptop and my PC data is transferred directly.
On the topic of the p2p relay it could expose IP addresses and device meta data. I've not done digging yet into the relays. But then again most DHTs do and even something like synthing has relays like this.
Yep. I've not tried it yet. Finally came around to playing around with it though. What I noticed is by default it syncs to the backup and I can't figure out how to turn it off yet. That said the files are decrypted locally with the keys made when the account is created. About to look more into the privacy policy.
This is still unclear for me to understand how sync works, because if it does not suit me, mo way I would be using it.
For example I mostly type on mobile, then when I open my laptop, the app will try to sync between my phone and my laptop, with their server helping establishing the connection? I don’t see how its gonna work well since both has to be online and have good Internet at the same time
No different than syncing to a server. Many video calls are implemented with p2p up to a certain amount of participants. Text is less demanding in comparison. I've not dived into the code yet but p2p relays typically just coordinate what IPs need to connect. In your case, once the connection is established the phone is directly transferring data with your laptop. No server in between.
