Privacy Policy

When you create an account we collect your email address. When you subscribe to Pro we collect payment information — this is processed entirely by Stripe and we never see or store your card details.

We also store the chart projects you create (titles, data, and settings) so you can access them across sessions.

• To authenticate your account and keep your projects saved
• To process your Pro subscription payments via Stripe
• To send transactional emails (password reset, subscription receipts)
• We do not sell your data or use it for advertising

• Supabase — stores your account and project data. See their privacy policy at supabase.com/privacy.
• Stripe — handles all payment processing. See their privacy policy at stripe.com/privacy.
• Vercel — hosts the application. See their privacy policy at vercel.com/legal/privacy-policy.

We use cookies only to keep you logged in. We do not use tracking or advertising cookies.

Your account and projects are retained until you delete them or request account deletion. To delete your account, email us at the address below.
