Privacy Policy

Last updated: June 2026

Craft MCP is a personal early-access project operated by Maximilian Bruhn ("the operator"), reachable at maximilianbruhn1@gmail.com. It is not operated by a company. This page explains what data the service touches and why, in plain language.

What we store

• Account data. Your email address, display name, and workspace membership, stored in Supabase when you create an account.
• Writing content. Text you seed, approve, reject, or validate is stored as part of your style profiles — that is the product. It stays attached to your workspace and is not used to train models or shared with other users.
• Usage events. Which tools you call and when, used for quota enforcement and the usage dashboard.
• Waitlist entries. Email, selected AI tools, and any writing-sample links you choose to submit.

Who processes it

The service runs on a small set of processors: Supabase (database and authentication), Vercel (hosting and anonymous web analytics), Stripe (payments, if you subscribe), Resend (transactional email), and LLM providers used by the style engine to analyze text you explicitly submit. No data is sold or shared for advertising.

Your rights

Under the GDPR you can request access to, correction of, or deletion of your data at any time — email maximilianbruhn1@gmail.com and it will be handled directly by the operator. Deleting your account removes your profiles, memories, and usage history.

Retention

Data is kept while your account exists. Waitlist entries are deleted when the service winds down or on request. This is an early-access service: expect the occasional reset, announced beforehand.

Cookies

Only what sign-in requires (Supabase session cookies). No third-party advertising or tracking cookies.
