Privacy Policy

1. Information We Collect

When you create an account we collect your email address and display name. When you use the app we store your flashcard decks, study progress, and scheduling data. If you subscribe to a paid plan, our payment processor (Stripe) collects billing information such as your payment method and billing address — we do not store your full card number on our servers. We also collect basic analytics (page views, feature usage) through Google Analytics 4 via Google Tag Manager.

2. How We Use Your Data

• Provide, maintain, and improve the iwill.study service
• Sync your decks and study progress across devices
• Send transactional emails (account verification, password resets)
• Analyze aggregate usage patterns to improve the product
• Process payments and manage your subscription

We do not sell, rent, or share your personal data with third parties for marketing purposes.

3. Data Storage & Security

Your data is stored securely using Supabase (hosted on AWS) with encryption at rest and in transit. Authentication is handled via Supabase Auth with industry-standard protocols. We retain your data for as long as your account is active.

4. Cookies & Tracking

We use essential cookies for authentication and session management. Google Tag Manager and Google Analytics 4 may set additional cookies for anonymized usage analytics. You can disable non-essential cookies in your browser settings.

5. Third-Party Services

• Supabase — authentication, database, and file storage
• Google Analytics 4 — anonymized usage analytics
• Vercel — hosting and edge delivery
• Stripe — payment processing for web subscriptions
• Apple — payment processing for iOS in-app subscriptions

Each service has its own privacy policy governing their handling of data.

6. Your Rights

You have the right to:

• Access the personal data we hold about you
• Request correction of inaccurate data
• Request deletion of your account and all associated data
• Export your flashcard data at any time

To exercise any of these rights, contact us at [email protected].

7. Children's Privacy

iwill.study is not directed at children under 13. We do not knowingly collect personal information from children. If you believe a child has provided us with personal data, please contact us and we will delete it promptly.

8. Changes to This Policy

We may update this policy from time to time. We will notify you of significant changes by email or through the app. Your continued use of iwill.study after changes constitutes acceptance of the updated policy.
