Privacy Policy

What we collect

When you create an account, we store your name, email address, and a hashed password. If you sign in with GitHub or Google, we receive your public profile information from those providers.

When you use Mantle, we store the projects you create, page content, element definitions, and deployment metadata. All content you edit is committed to private GitHub repositories that Mantle manages on your behalf.

How we use it

Your data is used to provide the Mantle service: authenticating you, saving your projects, syncing content to GitHub, and deploying to Vercel. We do not sell your data or use it for advertising.

Analytics

We use Little Friend for privacy-friendly analytics. It sets no cookies and does not store IP addresses. To connect the pages you view in one visit, it keeps a random id in your browser tab's session storage. The visit ends after 30 minutes of inactivity, and the id is gone when you close the tab. If your browser sends Global Privacy Control, your visit is only counted, never connected.

Some visits are recorded as a copy of the pages you view. We chose to show the text on our pages in these recordings. What you type or choose in forms is never recorded, email addresses and phone and card numbers stay masked, and recordings are deleted within 7 days.

Third-party services

Mantle integrates with GitHub (for content storage), Vercel (for deployments), and Resend (for transactional emails). Each service receives only the data necessary to perform its function. AI features use Anthropic's Claude API — content sent for AI processing is not stored by Anthropic beyond the request.

Data storage

Application data is stored in a PostgreSQL database. Passwords are hashed with bcrypt. We use HTTPS for all connections.

Your rights

You can export or delete your data at any time by contacting us at support@zvndev.com. Deleting your account removes all associated projects, pages, and elements from our database.
