Privacy Policy
Fontjohn ("we", "our") is operated by Sesohq. This page explains what data we collect when you use fontjohn.com, why we collect it, and how it's handled. Plain English. No tricks.
1. What we collect
Account info.When you sign in with Google we receive your email address, display name, and profile picture from Google's OAuth response. We do not request or store your Google password.
Generations. Prompts you type, reference images you upload, and the fonts our AI generates from those inputs. Generated font sheets are stored in our Supabase project so you can access them across devices.
Subscription + billing. If you upgrade to a paid plan, Stripe processes your payment and we store a Stripe customer ID against your account. We do not store your card number — Stripe does.
Usage logs. Server logs of requests (IP, timestamp, route) for abuse prevention and debugging. Standard Vercel access logs apply.
2. What we don't collect
No tracking pixels, no advertising cookies.
We don't sell your data. We don't share generations or prompts with third parties for marketing.
We don't train public AI models on your private fonts. Your generations stay scoped to your account.
3. Third-party services
4. Cookies + local storage
Session cookies from Supabase to keep you signed in. Set on this domain only.
IndexedDB cache in your browser to make font history snappy. Lives on your device, never sent anywhere.
No third-party trackers.
5. Your rights
- Delete any individual font from the History panel.
