Privacy Policy

1. What This Policy Covers

This policy applies to the HYPHO mobile app and the HYPHO website at hypho.ai. By creating an account or using HYPHO, you agree to the practices described here.

2. Information We Collect

Account Information

When you create a HYPHO account, we collect the information you provide:

• Email address
• Phone number (if you choose phone-based sign-in)
• Display name

Sign-In Information from Google and Apple

If you sign in using Google or Apple, those services share certain profile information with us. We only receive what they provide as part of the sign-in flow:

• Google Sign-In: Your name, email address, and profile photo
• Apple Sign-In: Your name and email address (or Apple's private relay email if you choose to hide your real email)

We never receive your Google or Apple password.

Learning and Progress Data

To personalize your experience and save your progress, we store:

• Lessons and courses you have completed
• Quiz results and scores
• Your overall learning progress

This data is stored in our Firebase database (Firestore) and is tied to your account.

User Content

If you upload or save any content within the app, that content is stored in Firebase Cloud Storage and associated with your account.

Device and App Identifiers

As a standard part of using Firebase's infrastructure, certain technical information is collected automatically:

• Firebase Installation ID — a unique identifier assigned to your specific app installation (not tied to your name or email)
• Operating system and device type
• App version

Usage and Performance Data

Firebase may automatically collect app usage and performance data, including screen views, session duration, feature interactions, app start time, and crash reports. This data is aggregated and used solely to understand how the app is performing and to improve the user experience. It is processed by Google under their privacy policy.

In-App Purchase Information

If you make a purchase within HYPHO, the transaction is processed entirely by Apple through the App Store. HYPHO receives only the confirmation of your purchase status (for example, whether your subscription is active). We never receive your credit card number or full payment details.

Website Visitors (hypho.ai)

The HYPHO website does not collect personal information directly. However, two services involved in running the site may process limited data:

• Google Fonts — used to load our typography. Google may log your IP address and browser type when your browser requests fonts from Google's servers.
• Vercel — our website host. Vercel retains standard server access logs that may include your IP address, browser type, pages visited, and timestamps. These logs are used for security and operational purposes only.

3. How We Use Your Information

We use the information we collect to:

• Create and manage your account
• Save and sync your learning progress across devices
• Deliver a personalized learning experience
• Verify and process in-app purchases
• Maintain the technical operation and security of the app
• Respond to your support requests and questions
• Comply with legal obligations

We do not sell your personal information. We do not use your data for advertising.

4. How We Share Your Information

We share data only with the service providers necessary to operate HYPHO. Each provider is required to protect your data to a standard equal to or greater than what is described in this policy, in compliance with applicable privacy laws.

We do not share your data with advertising networks, data brokers, analytics companies, or any third parties not listed above.

5. Data Retention

We retain your account data for as long as your account remains active. If you delete your account:

• Your account information, learning progress, and uploaded content will be deleted from our systems
• Firebase may retain anonymized technical logs for a limited period in accordance with Google's standard data retention policies

Server logs retained by Vercel are governed by Vercel's data retention policies.

6. Your Rights and Choices

Access and Correction

You can view and update your account information at any time within the HYPHO app settings.

Account Deletion and Data Erasure

You have the right to delete your account and all associated personal data. To do so:

• Use the account deletion option in the HYPHO app settings, or
• Email us at tyler.ericcsenm@gmail.com with the subject line "Delete My Account"

We will process your request within 30 days.

Revoking Consent

If you signed in with Google or Apple, you can revoke HYPHO's access to your account through your Google or Apple account settings at any time. Revoking access will sign you out of HYPHO and prevent future sign-in using that method, but will not delete the data already stored in your HYPHO account. Contact us to request full data deletion.

Washington State Residents

Under the Washington Privacy Act, you have the right to:

• Know what personal data we hold about you
• Correct inaccurate personal data
• Delete your personal data
• Obtain a copy of your personal data in a portable format
• Opt out of the sale of personal data (we do not sell personal data)

To exercise these rights, contact us at tyler.ericcsenm@gmail.com.

7. Children's Privacy

HYPHO is not directed at children under the age of 13. We do not knowingly collect personal information from anyone under 13. If you believe we have inadvertently collected information from a child under 13, please contact us at tyler.ericcsenm@gmail.com and we will delete it promptly.

8. Data Security

We take reasonable steps to protect your information, including relying on the security infrastructure provided by Google Firebase. However, no system is 100% secure. We cannot guarantee that your data will never be accessed, disclosed, or altered by a third party in an unauthorized way. If you believe your account has been compromised, contact us immediately.

9. Third-Party Links

The HYPHO website and app may contain links to external websites and social platforms. This Privacy Policy does not apply to those third-party services. We encourage you to review their privacy policies before sharing any personal information with them.

10. Changes to This Policy

We may update this Privacy Policy from time to time. When we do, we will revise the "Last Updated" date at the top of this page. If changes are material — meaning they meaningfully affect your rights or how we handle your data — we will notify you via the app or by email. Continued use of HYPHO after changes take effect constitutes your acceptance of the updated policy.
