Privacy Policy

Last updated: February 28, 2026

The Rationalist ("we", "our", or "the app") is a 365-day Quran study application. We are committed to protecting your privacy. This policy explains what data we collect, how we use it, and your rights.

Data We Collect

The Rationalist stores all user data locally on your device. We do not operate servers that store your personal information. Specifically:

• Profile information (optional name, faith background, purpose) is stored only on your device and is never transmitted.
• Reading progress, journal entries, reflections, streaks, and preferences are stored locally using on-device storage.
• No account creation is required to use this app.

Subscription Data

If you purchase a subscription (Plus or Pro), the transaction is processed by Apple through the App Store or Google through the Play Store. We use RevenueCat, a third-party service, to manage subscription status. RevenueCat receives an anonymous app user ID to track your entitlements. RevenueCat's privacy policy is available at revenuecat.com/privacy.

Rumi AI

The app includes Rumi AI, an optional AI-powered scholarly companion available to Pro subscribers. When you use Rumi AI:

• Your messages and conversation history are sent to our server (hosted on Cloudflare Workers), which forwards them to Anthropic's Claude API to generate responses.
• We do not store your conversations on our servers. Messages are processed in real-time and not retained after the response is delivered.
• Anthropic may process your messages in accordance with their privacy policy. Anthropic's API usage policy states that API inputs are not used to train their models.
• No personal identifiers (name, device ID, etc.) are sent with your Rumi AI messages.

Audio Narration

The app may download pre-generated audio files from our content delivery network (hosted on Cloudflare) for narration features. If pre-generated audio is not available, the app uses your device's built-in text-to-speech engine. No personal data is transmitted during audio playback.

Analytics and Tracking

We do not use analytics services, advertising SDKs, or any third-party tracking tools. We do not collect usage analytics, device identifiers, or behavioral data.

Notifications

If you enable daily reminders, notifications are scheduled locally on your device. No notification data is sent to external servers.

Third-Party Services

• Apple App Store / Google Play Store — processes subscription payments.
• RevenueCat — manages subscription entitlements using an anonymous ID.
• Cloudflare Workers — hosts the Rumi AI proxy server and audio content delivery. No user data is stored.
• Anthropic (Claude API) — processes Rumi AI conversations. Messages are not stored or used for model training.

Your Rights

You have the right to access, correct, or delete your personal data. Since all data is stored locally on your device:

• You can view and edit your profile in the app settings.
• You can delete all app data by uninstalling the app.
• To cancel a subscription, visit your Apple ID or Google Play subscription settings.
• RevenueCat data can be deleted by contacting us at the email below.

Children's Privacy

The Rationalist is not directed at children under 13. We do not knowingly collect personal information from children.

Changes to This Policy

We may update this policy from time to time. Changes will be reflected on this page with an updated date.
