Privacy Policy

Last Updated: January 2026

This Privacy Policy explains how Caffeinated Math, an umbrella of HJJB, LLC (“we,” “us,” or “our”), handles information when you use webRios (“the App”).

1. Our Privacy Commitment

webRios is designed with privacy as a priority. Your R code, scripts, and data are processed entirely on your device. We do not collect, transmit, or store your code or computation results.

2. What We Don’t Collect

We do not collect:

  • Your R code or scripts
  • Your data files or computation results
  • Your plots or visualizations
  • Your variable names or values
  • The contents of your files

All R computation happens locally on your device. We have no access to what you write or run.

3. What We May Collect

Device Information

When you use the App, we may collect basic device information for compatibility and support purposes:

  • Device type and model
  • iOS version
  • App version

Crash Reports

If the App crashes, anonymous crash reports may be sent to help us improve stability. These reports contain technical information about the crash but not your code or data.

Analytics

We may use Apple’s App Analytics to understand general usage patterns. This data is aggregated and anonymized by Apple before we receive it.

4. Tracking

We do not use advertising identifiers, do not participate in ad networks, and do not track your activity across other apps or websites. The App does not request permission through Apple’s App Tracking Transparency framework because there is nothing to track.

5. Third-Party Services

R Package Repository

When you install R packages, your device connects directly to the webR package repository (repo.r-wasm.org). This connection is between your device and the repository. We do not intercept, relay, or log these requests. Other than package downloads when you request them, the App does not make network requests.

Apple Services

As an iOS app, standard Apple services may apply, including App Analytics and crash reporting. See Apple’s Privacy Policy for details.

6. Data Storage and Security

Your R scripts, data files, and app settings are stored locally on your device in the App’s private storage area, which is protected by the iOS security sandbox. This data:

  • Remains on your device
  • Is accessible only to the App
  • May be included in iCloud backups if enabled
  • Is deleted when you uninstall the App

7. Data Retention

Since we do not collect personal data from the App, there is no user data retained on our systems. Crash reports and analytics data processed through Apple are subject to Apple’s data retention policies.

8. Children’s Privacy

The App is intended for users aged 18 and older. The App does not contain adult content; this requirement exists to avoid any risk regarding data from minors. Because all computation and storage happens entirely on your device, we do not collect information from any user, regardless of age.

9. Your Rights

Since the App does not collect personal data, most data rights can be exercised directly on your device by managing or deleting your files. Uninstalling the App removes all locally stored data.

California residents: We do not sell or share personal information as defined under the California Consumer Privacy Act (CCPA/CPRA).

EU/EEA residents: If you have questions about your rights under the General Data Protection Regulation (GDPR), please contact us at the address below.

10. Changes to This Policy

We may update this Privacy Policy occasionally. Changes will be reflected in the “Last Updated” date at the top of this page and communicated through App Store update notes for significant changes.
