NoteLinker

NoteLinker Privacy Policy

Last updated 15 September 2026

This privacy policy covers NoteLinker, the HubSpot app. It does not cover the other apps we publish or our custom integration service, each of which has its own.

What this app does with your data

NoteLinker moves data between your HubSpot account and your Notion account, in the directions you configure. It runs on our servers, on your behalf, using access you grant through each platform's own OAuth consent screen. You can withdraw that access at any time from either side, and the sync stops.

What we read from Notion

  • The Notion pages you choose to sync, and the content needed to render them on a HubSpot record.

What we access in HubSpot

Only the scopes below, each requested on the consent screen before the app is installed:

  • Read and write the contact and deal records you attach a page to, so the page appears on the right timeline.

What we store, and why

The app keeps the minimum needed to make the sync correct and repeatable. Records that cross between systems are not warehoused: what is stored is the link between them.

  • OAuth access and refresh tokens for Notion and HubSpot, used only to run your sync.
  • A mapping between each Notion page and the HubSpot record it appears on.

What we never do

  • We never sell your data or share it with advertisers.
  • We never use your Notion content to train models.
  • We never read pages you have not shared with the integration.

Sub-processors

The app runs on Vercel and stores its data in a managed PostgreSQL database. Payments, where the app is paid, are handled by Stripe and we never see or store your card details. Transactional email is sent through Resend. Each is used only to operate the app.

Retention and deletion

Uninstalling the app from HubSpot revokes our access immediately. Email michael@stacktie.com to have the stored records deleted, and we will confirm when it is done. Sync logs are swept on a rolling schedule regardless.
