No S3, no CouchDB, no server of your own. Install, enter a login code, sync.
AES-256 on-device encryption of contents and file names. Servers hold ciphertext only. How it works →
Conflicts keep both versions. Old versions kept 30–90 days. Files stay plain Markdown on disk.

No. With an encryption passphrase set (strongly recommended when you link a vault), your notes and their file names are encrypted with AES-256-GCM on your device. What reaches our servers and storage is ciphertext with random IDs. We couldn't hand your notes to anyone even if we wanted to.
Your synced data becomes unrecoverable — that's the flip side of real end-to-end encryption. Your local files stay untouched, so you can reset and re-sync with a new passphrase.
Yes — iOS and Android. Notes sync while Obsidian is open (mobile operating systems don't allow background sync for any plugin).
Architecture, not corner-cutting. Your files travel directly between your device and object storage; our server only coordinates metadata. That's radically cheaper to run, and we pass it on. How sync works →
Yes — community plugins may require accounts and payment as long as it's disclosed, which we do. Obsyncian is an independent project, not affiliated with Obsidian.
The plugin lets you point at any server URL, and the sync API is documented. A self-hosting guide is planned.
