I'm wanting to integrate Brix into our Hubspot account and have been questioned internally if this will present any GDPR issues. I am new to web building and developing, so excuse my lack of knowledge. There didn't seem to be a doc available.
While I can't offer legal advice or speak to briX's privacy policies, I suspect the briX integration simply leverages HubSpot's existing content tools and doesn't have access to your contact information.
I highly recommend checking with briX, however, and working with your legal counsel to ensure compliance for your specific situation.
