Privacy Policy

Last Updated: October 3, 2026

AURUM (the “App”) respects your privacy. This Privacy Policy explains what information the App handles, why it is used, and how you can manage it.

1. Information Collection and Use

The App handles the following information to provide its features, maintain security, and understand app use.

1-1. Device Information and Identifiers

1-2. User Content

1-3. Usage Data and Diagnostics

1-4. Purchase Information

2. Third-Party Services and Data Transfers

The App uses the service providers below to operate its features. They process information under their applicable terms and privacy policies.

2-1. OpenAI API (OpenAI, L.L.C.)

2-2. Cloudflare Workers (Cloudflare, Inc.)

2-3. Google Firebase and Google Analytics 4 (Google LLC)

2-4. Google AdMob (Google LLC)

2-5. RevenueCat (RevenueCat, Inc.) and App Stores

3. Data Storage and Security

3-1. Storage Location

Chat history, selected Study images, extracted source material, generated Study cards/material, and review state are stored locally on your device. The App’s AI backend does not intentionally persist AI request content after processing. OpenAI and infrastructure providers may retain information as described above and under their applicable policies.

3-2. Security

AI requests are sent over HTTPS/TLS. The App and its service providers use security measures appropriate to their roles and applicable policies.

4. Your Choices and Rights

4-1. Local Data Deletion

Use the App’s available delete actions to remove individual Chat or Study content. Uninstalling the App removes its local data from the device, subject to the operating system’s backup and storage behavior. Deleting local data does not delete content that a third-party provider may retain under its security, abuse-monitoring, or legal obligations.

Before the first AI request, the App asks whether you allow the described processing. You can change this decision at any time in AI Data Settings in Study or Billing. Revoking permission blocks new Chat, Study, and problem-set AI network requests until you allow processing again. Revocation does not delete existing local Chat or Study data, and offline Study review remains available. It does not retroactively delete information a third-party provider retains under its applicable security, abuse-monitoring, or legal obligations.

4-3. Advertising Choices

You can manage advertising and tracking permissions in your device settings. The App’s AI content is used for the feature you request and is not used for ad tracking.

5. Children’s Privacy

The App is intended for educational use and is not specifically directed to children under 13. Parents and guardians should supervise children’s use of the App and device settings.

6. Changes to This Privacy Policy

This policy may be updated to reflect legal or service changes. Significant changes will be notified in the App or on this page.
