What to check before you pick one
- The plan, edition or add-on the BAA needs, when the answer is specific plans, and whether yours includes it.
- What the BAA covers and leaves out. Each entry lists it where the vendor says so.
- Who signs it and how: some vendors have an admin accept the BAA inside the account, others send it through sales.
- The date we checked. Vendors change their plans and terms, so confirm the current terms with the vendor before you send it patient data.

The ad tracking gap these tools leave
A BAA with a site builder tool covers the data that tool handles for you. A pixel on the same page sends data to a different company, and this directory lists Meta, Google Ads and TikTok as not signing a BAA. The conversion your campaigns learn from has to reach them without health information.
How Curve helps
- Curve carries the conversion signal to your ad platforms separately, under its own BAA, so you can keep the tools you use for what they do well.
- Curve replaces browser ad pixels with one script and sends conversions server-side to Meta, Google Ads, TikTok, Microsoft Advertising and LinkedIn from Curve's servers.
- Curve detects PHI-like patterns, such as condition names, form answers and emails in URLs, before data reaches an ad platform, and flags them so they can be stopped at the source.
- Each platform receives only a fixed list of fields. Contact identifiers are off by default on Meta, Google Ads and TikTok, and events can use neutral names.
- Event Logs show what Curve sent to each platform and what the platform accepted.
- Curve signs a BAA on every plan, and Curve's team does the setup for you, typically live in about a week.

Frequently asked questions
Which site builder tools sign a BAA?
In Curve Compliance's BAA Directory, GoDaddy, Vercel and Wix sign a BAA only on specific plans. Each entry quotes the vendor and gives the date we checked.
Is a site builder tool HIPAA compliant without a BAA?
Not for patient information. A HIPAA covered entity needs a business associate agreement with any vendor that handles its patients' Protected Health Information. A vendor page that calls a tool HIPAA compliant is not the same as a signed BAA, so keep patient information out of the tool until the vendor signs one with you.
Do I need a BAA with a site builder tool?
A HIPAA covered entity needs one with any vendor that handles its patients' Protected Health Information, for example in bookings, intake answers or messages. Each entry in this list says whether the vendor signs a BAA and on which plans.
Does a BAA with a site builder tool cover my ads?
No. A BAA covers the data one vendor handles for you. A pixel sends data from the visitor's browser to Meta, Google or TikTok, and none of them is a party to that BAA. Curve Compliance sends your conversions to them server-side, with a fixed list of fields, under the BAA it signs on every plan.
