Notional — Privacy Policy

Last updated: 21 June 2026

Notional is a free, open-source Obsidian plugin that syncs your notes to your own Notion workspace. It is run entirely on your computer.

What we collect

Nothing. The developer of Notional operates no servers and does not collect, receive, store, sell, or transmit any of your data, notes, credentials, or usage information.

Where your data lives

• Your notes and your Notion access token are stored locally in your Obsidian vault (data.json) on your device.
• Your note content is sent only directly from your device to the Notion API (api.notion.com) to perform the syncs you request — never to any third party.

Authentication (OAuth)

Connecting to Notion uses the OAuth 2.0 Authorization Code flow with PKCE. No client secret is embedded in the plugin or held on any server. The authorization code is exchanged for a token directly between your device and Notion. The redirect page at /oauth-callback.html is fully static: it loads no third-party scripts, makes no network requests, uses no cookies or analytics, and only forwards Notion's response back into the Obsidian app on your machine.

Removing access

You can disconnect at any time by removing the access in your Notion settings (Settings → Connections) and/or clearing the token in Notional's settings.
