Clarification on Clipboard Data Sharing and Self-Hosting

[Havock94]

Hello,

I would like to understand how clipboard data is shared between devices.
Does it use Google's GCM/FCM, or is it handled through a server?

If it relies on a server, would it be possible in the future to host the server using Docker, allowing users to have full control over the shared data?

Thank you in advance for your time and support!

I would also like to know more about how data is synced.

Hi all, your clipboard data is encrypted end-to-end using AES-GCM-256, with the key derived locally from your "encryption key" and never transmitted. We currently utilize Supabase Postgres and Supabase Realtime for clipboard sharing.

Improving user privacy is a high priority, and P2P synchronization is high on our to-do list as a solution.

It's important to note that with our current setup, only encrypted data is ever sent over the internet from the clients. Our servers only handle this encrypted data.
