Privacy & Security
Where is my data?
Where is my data?
Sync data plane: Hetzner in Germany. Control plane (auth, metadata): Supabase Frankfurt. Vault contents are E2EE — we never see plaintext.
How does the encryption work technically (zero-trust)?
How does the encryption work technically (zero-trust)?
LiveSync encrypts your vault directly on your device with a passphrase only you know. Encryption and decryption happen locally in Obsidian — never on our servers. Only ciphertext ever reaches us; we store and sync encrypted data blocks only. That’s zero-trust: even with full access to our CouchDB servers, we couldn’t read your notes, because we simply don’t have the key.
Technical
Can I sync large files?
Can I sync large files?
LiveSync chunks files. Max ~10 MB per CouchDB document (incl. E2EE overhead). Huge videos belong in object storage — not in the vault.
Do I need a special Obsidian plugin?
Do I need a special Obsidian plugin?
The official community plugin “Self-hosted LiveSync”. No companion plugin needed for the MVP. See the plugin directory.
Why does my vault slowly get bigger during the day?
Why does my vault slowly get bigger during the day?
That’s caused by the revisions created for your vault — standard behavior of the CouchDB database. We run compacting (deleting old revisions) once every 24 hours, which shrinks the database again.
