Privacy

Your account

Supabase Auth manages sign-in, your verified email, linked Google identity, and any provided profile name or image. Supabase stores the account and manages session refresh. Its SDK stores your session on this device to keep you signed in. Our Supabase database associates your purchases with your account.

Payments

Stripe handles payment details. We store the purchase status, transaction identifiers, purchase date and receipt link to manage Pro access. We do not receive or store your card number. Supabase Auth sends sign-in codes through the configured email delivery provider. Purchase welcome emails use our configured transactional sender.

Your images

Calculators and free image exports run in your browser. Your current image may be saved on this device for up to 24 hours when you sign in or start checkout. Pro previews and exports send the image configuration to our server to render the image; we do not save those images to our database.

Usage data

We count visits, calculator use, template choices, exports and payment steps using a random session identifier. These analytics exclude your email, account name, input amounts and chart values. Usage reports cover up to 90 days. Browser Do Not Track and Global Privacy Control settings disable browser analytics.

Google, Stripe and Resend also process information under their own privacy policies when you use those services.
