This Privacy Policy explains how Tiku collects, uses, and shares information about you when you use our websites, applications, and related services (the "Services"). We are committed to protecting your privacy and handling your data responsibly.

2. Information We Collect

  • Account Information: name, email address, password hash, and any profile details you provide.
  • Educational Content: essays, prompts, notes, application plans, college preferences, and related content you create or upload.
  • Transaction Information: payment method details (processed by Stripe), billing history, and subscription status.
  • Usage Information: device and browser data, IP address, pages viewed, referring pages, and interactions collected through analytics and performance tools (e.g., Vercel Analytics, Speed Insights).

3. How We Use Information

4. Data Processing and AI

To provide AI-powered capabilities, we may process your prompts and selected content with AI model providers such as OpenAI. We take steps to limit sharing to what is necessary for the requested feature, and we disable provider-side training on your data where supported. We do not sell your personal information.

5. Cookies and Tracking

We use cookies and similar technologies to keep you signed in, remember preferences, and analyze usage. You can control cookies through your browser settings; however, disabling some cookies may affect functionality.

6. Sharing of Information

  • Service Providers: We share information with vendors that help deliver the Services (e.g., Supabase for authentication and storage, Stripe for payments, analytics providers for performance monitoring).
  • Legal Compliance: We may disclose information if required by law, regulation, legal process, or government request.
  • Business Transfers: In connection with a merger, acquisition, or asset sale, your information may be transferred.

7. Data Security

We implement technical and organizational measures designed to protect your information, including encryption at rest and in transit provided by our infrastructure providers. No system is 100% secure; you are responsible for safeguarding your account credentials.

8. Data Retention

We retain information as long as your account is active and as necessary to provide the Services and comply with legal obligations. You may request deletion of your account and associated data as described below.

9. Your Rights

  • Access and update your profile information in the app.
  • Request deletion of your account and data, subject to certain exceptions.
  • Opt out of non-essential communications.

10. Children’s Privacy

Tiku is not directed to children under 13. If we learn that we have collected personal information from a child under 13 without parental consent, we will take steps to delete such information.

11. International Users

If you access the Services from outside the United States, you understand that your information may be processed in the United States or other jurisdictions where we or our providers operate, which may have different data protection laws than your country of residence.

12. Changes to this Policy

We may modify this Privacy Policy from time to time. If changes are material, we will provide notice (for example, by email or in-product notification). Your continued use of the Services after the effective date of the changes constitutes acceptance of the updated policy.
