Privacy Policy

Last updated: June 2026

This Privacy Policy describes how Joyful Muslims (EMV-registered, CVR 46387996) collects, uses, and protects your information when you use the Joyful Muslims Audiobook application (the "App") or this website.

1. Information We Collect

Account Information

When you create an account in the App, we collect your name, email address, and a unique user identifier. If you use Sign in with Apple, we receive only the information Apple provides based on your choices (which may include a private relay email).

Usage Data

We collect listening progress, bookmarks, and interaction data to provide features like "Continue Listening" and reading streaks. This data is linked to your account and used solely for app functionality.

Purchase History

We record your subscription tier and any one-time in-app purchases to manage your entitlements. Payment processing is handled entirely by Apple — we never see or store your payment details.

Device Information

We collect basic device information (device type, OS version) for compatibility and crash reporting.

2. How We Use Your Information

• To provide and maintain the App's core features (listening, progress sync, bookmarks)
• To manage your subscription and entitlements
• To send push notifications you have opted into (streak reminders, new book alerts)
• To improve the App based on aggregate, anonymised usage patterns

3. What We Do NOT Do

• We do not sell your personal data to third parties.
• We do not show advertising inside the App.
• We do not share your personal data with data brokers or marketing partners.
• We do not store your Apple ID password or payment information.

We do use your device's advertising identifier (IDFA) and third-party ad-measurement tools to understand which marketing campaigns introduce people to Joyful Muslims — but only after you grant permission, and only to measure our own campaigns (never to show ads in the App or to sell your data). See Section 5.

4. Data Storage & Security

Your data is stored on secure servers. Listening progress and account data are transmitted over HTTPS. We retain your data for as long as your account is active. You can request deletion at any time.

5. Third-Party Services

We use the following external services to operate the App. Each is listed with the specific data category we share and why.

• Apple StoreKit: Subscription and purchase management. Handled entirely by Apple — we receive only the transaction ID and entitlement status.
• Apple Push Notification Service: Optional notifications. Opt-in only.
• Cloudflare R2 & Pages: Audio and content delivery, website hosting. Standard HTTP request logs only (IP, user-agent) and then discarded per Cloudflare's retention policy.
• Anthropic, PBC (Claude): Large language model used to assist with translation drafting, and to answer questions typed into the "Ask the library" box on this website — the question text is sent; nothing that identifies you is. The App itself sends no message or personal data to Anthropic. Anthropic does not use data submitted via their API to train their models. Anthropic privacy policy →
• OpenAI, L.L.C. (GPT-4): Used in translation drafting and verification workflows. Same data-minimisation principles apply: only the material needed to generate the translation is sent. OpenAI does not use data submitted via their API to train their models. OpenAI privacy policy →
• Meta Platforms, Inc. (Facebook / Instagram): Advertising-campaign measurement. If you grant tracking permission, your advertising identifier (IDFA) and aggregate events (such as install, sign-up, and subscription) are shared with Meta so we can measure which Meta ad campaigns introduce people to the App. Meta privacy policy →
• Google LLC (Firebase / Google Analytics for Firebase, Google Ads): The same advertising-campaign measurement purpose, and likewise only after you grant tracking permission. Google privacy policy →

App Tracking Transparency & advertising measurement. Shortly after first launch, iOS asks for your permission to track. If you allow it, we use your device's advertising identifier (IDFA) together with the Meta and Google/Firebase tools above — and Apple's privacy-preserving SKAdNetwork — solely to measure which advertising campaigns lead to installs and subscriptions. We do not show ads inside the App, and we do not sell your data. If you decline, advertising measurement is turned off and nothing else about the App changes. Our own product analytics are first-party and anonymised; you can opt out in Settings → Privacy.

AI and your data. Since version 3.1 (September 2026) the App contains no AI chat: nothing you type in the App is sent to a third-party AI provider. Earlier versions carried the JM Scholar assistant; if you are still on one, a message you send it travels through our servers to Anthropic with the current book's title, is not used to train any model, and is kept only as long as needed for follow-up context. AI is otherwise used behind the scenes in preparing translations (Section 5) and, on this website only, to answer questions typed into the "Ask the library" box.

6. Children's Privacy

The App is designed for users aged 13 and above. We do not direct the service to children under 13 and we do not knowingly collect personal information from children under 13.

If you are a parent or guardian and believe that a child under 13 has provided us with personal information, please email [email protected]. We will promptly verify and delete the information and any associated account.

Within the European Union, the minimum age for valid consent to process personal data is 16 in some Member States (13 in others). Where a stricter age applies, users below that age must obtain verifiable consent from a parent or legal guardian before creating an account or enabling personalised features.

In all cases:

• We do not show advertising inside the App.
• We do not knowingly collect data from, or enable advertising measurement for, anyone we know to be under 13.
• We do not share personal data with data brokers or marketing partners.
• Push notifications require explicit opt-in; no notifications are sent to accounts without active consent.

7. Your Rights (GDPR)

As a Denmark-based company, we comply with the EU General Data Protection Regulation. You have the right to:

• Access your personal data
• Correct inaccurate data
• Request deletion of your data
• Export your data in a portable format
• Withdraw consent at any time

To exercise any of these rights, contact [email protected].

8. Data Retention

We retain your data for as long as your account exists. If you delete your account, we will remove your personal data within 30 days, except where retention is required by law.

9. Changes to This Policy

We may update this Privacy Policy from time to time. We will notify you of significant changes through the App or by email.
