Privacy Policy

Last updated: August 25, 2026

1. Information We Collect

Physics AI processes only the information needed to provide the feature you choose to use:

  • Problem images, question context, and follow-up messages you choose to submit for an AI response
  • Saved problems, images, quizzes, flashcards, study progress, and preferences stored on your device
  • Limited product analytics such as feature use, success or failure state, counts, timing, settings, and subscription status
  • An Apple DeviceCheck token on supported devices for service protection and abuse prevention
  • An assigned FeaturePortal app user ID, feature interactions, and any email address or feedback text you choose to submit through product-feedback features

2. How We Use Your Information

We use the information we collect to:

  • Generate explanations, tutor replies, quizzes, and flashcards that you request
  • Store your study data on your device and, when available, sync it through your private iCloud account
  • Measure reliability and improve product features without sending problem content in analytics events
  • Protect the online service from automated abuse
  • Present and manage App Store subscription offers and product-feedback features

3. Data Storage & Security

Your privacy is important to us:

  • Saved app content is stored locally on your device using SwiftData
  • When iCloud is available for Physics AI, Apple may sync app data through your private iCloud account
  • AI requests are sent over encrypted connections to an Ideas All Day proxy, which forwards them to Anthropic; Anthropic's standard API retention period is up to 30 days
  • The proxy does not store problem images or text. It stores a hashed DeviceCheck token and request IP for up to 24 hours, plus limited request diagnostics such as status, response time, project, model, byte and token counts, and errors
  • Analytics, commerce, and feedback providers retain the limited service data described here under their own policies
  • We do not sell personal data or use advertising networks

4. Third-Party Services

The app relies on the following service providers for specific functions:

  • Anthropic for requested problem analysis, tutor replies, quizzes, and flashcards
  • Aptabase for content-minimized product analytics
  • Apple for DeviceCheck, optional CloudKit sync, App Store distribution, and purchases
  • Superwall for presenting subscription offers and purchase-status features
  • FeaturePortal for an assigned app user ID, feature requests, votes, comments, and feature-view tracking

5. Your Choices

You can:

  • Delete individual saved problems and study content in the app
  • Manage Physics AI's iCloud data in Apple Settings
  • Remove the app to delete its local data
  • Manage or cancel subscriptions through your Apple ID settings
  • Contact us for privacy questions or deletion help

6. Children's Privacy

Physics AI is a general educational study aid and is not directed to children under 13. We do not knowingly collect personal information from children under 13. If you believe a child has submitted personal information, contact us so we can review the request.

7. Changes to This Policy

We may update this notice when the app or its providers change. The date at the top shows the latest revision.
