Microsoft vs Vercel Inc.

Microsoft's privacy statement covers an enormous product surface — Windows, Office, Azure, Bing, Xbox, and Copilot — and the data practices vary dramatically across them. The umbrella policy is deliberately vague, deferring almost all specifics to product-level documentation. Cross-product data combination, AI model training on your content, and employer/school access to your files and communications are the key risks most consumers don't realise they're accepting.

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.
