Privacy Policy

Your diagrams stay in your browser

The diagrams and documents you create are stored locally on your device (IndexedDB and localStorage). They are not uploaded to or stored on our servers by default.

What we process

• Payments: handled by Stripe. We never see or store your card details.
• AI features: when you use the AI co-editor or slide generation, the relevant diagram data and your instruction are sent to OpenRouter (a third-party model provider) to produce a response.
• Accounts (if enabled): when sign-in is enabled, authentication is handled by Clerk, which stores your account credentials per its own policy.
• Hosting: the app is served by Vercel, which may process standard request metadata (e.g. IP address) to deliver and secure the service.

Local storage

We use browser storage to remember your theme preference, your unlock status, and your in-progress diagrams. Clearing your browser storage removes this data.

Analytics

If product analytics are enabled, we collect aggregate, privacy-respecting usage events (e.g. that an export occurred) to improve the product — never the contents of your diagrams.

Third parties

Stripe, OpenRouter, Clerk (if enabled), and Vercel each process data under their own privacy policies. We encourage you to review them.
