Privacy Policy
Last updated: October 19, 2026
OneNote Manager ("the app") is a tool for browsing and editing your own Microsoft OneNote content. This policy explains what we store and why. We aim to hold the minimum data needed to run the service.
Account information
When you create an account we store your email address and an encrypted password hash through our authentication provider, Supabase. We use this only to sign you in and to send account emails (confirmation and password resets).
Your OneNote content
To read and edit your notebooks, you connect your Microsoft account. Microsoft returns an access token used to make requests to the Microsoft Graph API on your behalf. The website keeps its Microsoft connection in its authenticated session; the native app stores its connection in encrypted device storage. We do not copy, store, or index the contents of your OneNote notes on our servers — note content is fetched live from Microsoft and shown to you, then discarded.
Device drafts
The format editor can keep unfinished drafts in this browser or in encrypted native device storage so you can recover your work. These drafts stay on that device and do not sync between devices. Discard drafts you no longer need on each device.
App data we store
We store the items you star (their OneNote id and display name) and your settings (preferences such as your title prompts and default folder), scoped privately to your account with row-level security so other users cannot access them.
AI title generation
Optional AI features (title generation, summaries, cleanup) run against a local Ollama model on the machine hosting the app. Note text used for these features is not sent to any third-party AI service by the app.
Third parties
We rely on Supabase (accounts and database) and Microsoft (OneNote access). Your use of Microsoft OneNote is also governed by Microsoft's privacy terms.
Data deletion
Open Delete your account to permanently delete your OneNote Manager account, profile, starred items and settings. The same option is available in web and native Settings. Your Microsoft account and OneNote notebooks remain with Microsoft. Disconnecting clears this device's Microsoft connection; you can also remove OneNote Manager's permission in your Microsoft account settings. Device drafts remain under your control on each device.
