Privacy Policy

1. Introduction

VibeMath ("we", "our", "us") is an AI-powered math tutoring and video creation platform available at vibemath.app and on mobile. This Privacy Policy explains what data we collect, why we collect it, and how you can control it.

2. Data We Collect

Account information

• Name and email address (provided through Google or email sign-in)
• Profile photo (when supplied by your sign-in provider)
• Account creation date and last active timestamp

Math content you create

• Math problems and questions you type or speak into the app
• Chat messages exchanged with the AI tutor
• Videos generated from your prompts
• Collections and notes you save in your private library

Usage and performance data

• Feature interactions (which screens you visit, which actions you take)
• Error reports and crash logs (anonymized stack traces)
• App version, device type, and operating system

Subscription and billing data

• Subscription tier and billing status (we never see card numbers)
• Purchase and renewal timestamps

3. How We Use Your Data

• Service delivery — answering your math questions, generating videos, tracking your progress
• AI processing — your prompts are sent to our AI providers to generate answers and videos. No data is used to train those models without separate consent.
• Account management — authenticating you, managing your subscription, sending transactional notifications
• Safety and abuse prevention — detecting and blocking harmful or off-topic content
• Product improvement — aggregated, anonymized usage analytics

4. Data Retention

Generated videos, solutions, and chat conversations remain available until you delete them or delete your account. Temporary narration files used during rendering are removed after the final video is committed. Crash and error logs are purged after 90 days. Billing records are retained as required by applicable tax and accounting law.

5. Third-Party Services

We share data with the following processors only to the extent necessary to deliver the service:

• Google Firebase / Firestore — authentication and database hosting
• Google reCAPTCHA v3 / Firebase App Check — abuse prevention and verification that requests come from the authentic VibeMath web app. This service may process browser and device risk signals and set the necessary _GRECAPTCHA cookie.
• Google Cloud Storage — video file storage
• AI providers (Google Gemini and Anthropic Claude) — text reasoning and generation
• DeepInfra Kokoro — English text-to-speech narration
• RevenueCat — subscription and in-app purchase management
• Cloudflare — network edge and DDoS protection (no data stored)

None of these processors are permitted to use your data for their own purposes beyond service delivery.

6. Your Rights (GDPR / CCPA)

Depending on your location, you may have the right to access, correct, export, or request deletion ("right to be forgotten") of your data, and to object to or restrict certain processing.

To exercise any of these rights, use our account deletion page, email us at support@vibemath.app or use the "Delete account" option in your Profile. We will respond within 30 days. Some data (billing records) must be retained for legal compliance and cannot be erased early.

7. Account Deletion

You can permanently delete your account from the Android app by opening Profile and selecting "Delete account." If you no longer have access to the app, use our public account deletion page.

Account deletion removes your profile and associated VibeMath content. Billing, transaction, security, or fraud-prevention records may be retained where legally required. Google Play subscriptions must be cancelled separately.

8. Children's Privacy

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

9. Security

We use industry-standard security measures including TLS in transit, encrypted storage at rest, Firebase Authentication for identity, and IAM-restricted access to production systems. No internet transmission is 100% secure; we cannot guarantee absolute security.

10. Changes to This Policy

We may update this policy periodically. When we make material changes, we will notify you at least 14 days before the change takes effect. Continued use of the service after that date constitutes acceptance of the updated policy.
