Privacy Policy
Last updated: 4/7/2026
1. Information We Collect
We collect information you provide when signing up: email address, password (hashed), and project name. We also collect usage data such as API request counts, chart types rendered, and timestamps for billing and service improvement.
2. How We Use Your Information
We use your information to provide the Chart-Output service, process payments, send transactional emails (welcome, trial reminders, billing), and improve our product. We do not sell your data to third parties.
3. Data Storage and Security
Your data is stored on Supabase (PostgreSQL) and Stripe for payments. We use industry-standard encryption and security practices. API keys are stored as SHA-256 hashes; passwords are hashed by Supabase Auth.
4. Your Rights (GDPR / CCPA)
You may export your data, update your account settings, or delete your account at any time from the Settings page. Account deletion removes your profile, API keys, and usage data. Billing records are retained as required by law.
5. Cookies and Analytics
We use essential cookies for authentication. If we use analytics, we will disclose this and provide opt-out options.
