Your data
stays with you.

Your vault. On your GitHub. Notes on every device.

Sign inGitHub, or email.

Connect a repoInstall the GitHub App.

SyncThis server commits to main.

Quiet by default. Yours throughout.

Sign in, connect one repository, and keep writing. Devices stay in step. AI talks to your notes only with a token you mint.

Every deviceThe same plugin on desktop, Android, and iOS. No Electron, no extra client.

Your GitHubOptional backup on main. You own the repo. This server never asks for a personal access token.

MCP, on your termsSearch and read are enough for most agents. Create and modify stay off until you allow them.

Obsidian stays the editor. Syncidian is the quiet layer underneath — phones, laptops, and the agents you invite.

Privacy first

No profiles. No ads. No mining your notes. Your vault lives in Obsidian, and in the GitHub repository you connect — not as our product.

Only what it takes to know your devices are connected and in sync.

Connected devicesHow many devices are linked, and the name you gave each one.
PlatformmacOS, Windows, Linux, Android, or iOS — plus the plugin version on that device.
Sync healthLast seen, last successful sync, sync count, and how many files moved. Counts, not the notes themselves.

Access tokens are stored hashed. GitHub App secrets are encrypted. MCP never stores note bodies. Operators cannot open another person’s vault.
