Vercel Inc.

Vercel collects your account data, professional info, and — critically for developers — your source code and deployment content to run the platform. They don't run an ad business and explicitly prohibit staff from viewing your code except to fix support issues. The main caveats are AI product data collection, third-party marketing partners, and a California-specific admission that they may 'share' data for cross-contextual advertising for their own marketing.
