Wix Sync Privacy Policy
Last updated 15 September 2026
This privacy policy covers Wix Sync, 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
Wix Sync moves data between your HubSpot account and your Wix 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 Wix
- Wix contacts, including the fields your site collects on them.
- Wix form submissions and the form schemas that describe them, so the answers can be mapped to real HubSpot properties.
- The list of sites on your Wix account, so you can choose which one syncs.
What we access in HubSpot
Only the scopes below, each requested on the consent screen before the app is installed:
- Read and write contacts (crm.objects.contacts), to create or update the contact a submission belongs to.
- Read and write contact property definitions (crm.schemas.contacts), to create the properties your field map writes into.
- Submit forms (forms), so a Wix submission becomes a real HubSpot form submission rather than a timeline note.
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 both Wix and HubSpot, used only to run your sync.
- A mapping between each Wix contact and the HubSpot contact it corresponds to, so an update changes the same record instead of creating a second one.
- Your field mappings and which forms you chose to sync.
- A per record sync log, so you can see what arrived and why something did not. Swept on a schedule.
- Counts of records synced in the current month, for billing.
What we never do
- We never sell your data or share it with advertisers.
- We never use your contacts or submissions to train models.
- We never read Wix data outside the sites you connect.
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.
