Privacy Policy
Last updated: November 12, 2026
What we collect
Account data (name, email), business information you provide, photos and logos you upload, billing data (handled by Stripe, we never see full card numbers), usage events to improve the product, and cookies needed for login and language.
Data about your customers
When visitors send a request, book an appointment or chat on a site built with William, we process their name, contact details and messages on behalf of that business, which is the controller of that data. We act as its processor.
How we use it
To provide and improve the service, generate your content with AI, send transactional emails and reminders, prevent abuse, and bill you. We do not sell personal data.
Service providers
Hosting and database (Vercel, Supabase), AI (Anthropic, plus Google and OpenAI image models through the Vercel AI Gateway), payments (Stripe), email (Brevo), Meta and Google APIs when you connect them. They process data only on our instructions. If you connect William to an AI assistant (Claude, ChatGPT), the information that assistant reads from your account is then processed by its provider (Anthropic, OpenAI) under its own terms.
International transfers
Data may be processed in the United States. For EU users, transfers rely on the EU-US Data Privacy Framework or Standard Contractual Clauses.
Retention
Account data is kept while your account is active and deleted within 30 days after closure (backups within 90 days), except where the law requires longer retention (e.g. invoices).
Your rights
Access, correction, deletion, portability and objection (GDPR), and the right to know and delete (CCPA/CPRA). We do not sell or share personal information for cross-context behavioral advertising. Contact service-administratif@boosttoncab.com.
