1. Introduction

This Privacy Policy explains how Footnote / Footnote Cards ("we," "our," or "us") collects, uses, and protects information when you use our web application.

2. Information We Collect

We collect only the information necessary to operate the app:

  • Account Information:
    When you create an account, we collect information such as your email address and login credentials.
  • Payment Information:
    If you choose a Pro account, payments are processed securely through Stripe. We do not store or have access to your full payment details (such as credit card numbers).

3. How We Use Information

We use collected information solely to:

  • Provide and maintain the app
  • Authenticate users
  • Manage subscriptions and payments
  • Communicate important account-related information

4. Cookies and Similar Technologies

We use cookies and similar technologies to provide and improve our service. Cookies are small text files that are stored on your device when you visit our website.

Essential Cookies: We use cookies that are strictly necessary for the app to function properly. These cookies are essential for:

  • Authentication: Maintaining your login session so you don't have to sign in every time you visit or navigate between pages
  • Security: Protecting your account and ensuring secure access to your data

These cookies are essential for the app to work. Without them, you would need to log in on every page load, and some features may not function properly. We do not use these cookies for tracking, advertising, or analytics purposes.

If you disable cookies in your browser, you may still use the app, but you will need to log in each time you visit or navigate to a new page, and some functionality may be limited.

5. Third-Party Services

We use trusted third-party services to operate and improve the app:

  • Supabase — for authentication, database storage, and backend services
  • Stripe — for secure payment processing
  • Vercel — for hosting and deployment

These services may process limited user data on our behalf and only as necessary to provide their services. Each service handles data in accordance with its own privacy policy.

6. Data Security

We take reasonable measures to protect your information. However, no method of transmission over the internet or electronic storage is 100% secure.

7. Data Retention

We retain account information only as long as necessary to provide the service or comply with legal obligations. You may delete your account at any time.

8. Children's Privacy

The app is not intended for children under the age of 13, and we do not knowingly collect personal information from children.

We may update this Privacy Policy from time to time. Any changes will be posted on this page with an updated effective date.
