Privacy Policy

This Privacy Policy describes how Eliyahu Shwartz (“we,” “us,” or “our”) collects, uses, and protects information in the Interactive Books for Kids mobile application (the “App”). The App is intended for children aged 3–8 and complies with the U.S. Children’s Online Privacy Protection Act (COPPA), the EU General Data Protection Regulation including Article 8 on children (GDPR-K), and Google Play’s Designed for Families program policies.

The short version: We do not show advertising of any kind. We do not allow third-party advertising networks. We do not sell or share personal information. We collect only the minimum data needed to make the App work, and parents can request deletion of their child’s data at any time.

1. Information we collect

We collect the following limited information to operate the App. We do not request or collect a child’s name, email address, phone number, home address, photograph, voice recording, precise location, or any persistent identifier used for behavioral advertising.

• Anonymous account identifier. When the App first launches, Firebase Authentication generates a random, anonymous user ID (a UUID). This ID is not linked to a name or email and cannot be used to identify a child outside the App.
• Reading progress. The current page, completed books, and unlocked coloring rewards are stored in Cloud Firestore so the App can resume where the child left off and across devices if the family later signs in.
• Purchase records. If a parent subscribes through Google Play Billing or Apple StoreKit, the App records the subscription product ID and status. We never see or store payment card details — those are handled entirely by Google or Apple.
• Aggregated app usage events. Firebase Analytics records non-personal events such as which books were opened, how many pages were read, and how long sessions lasted. These events use the anonymous Firebase Instance ID and are not cross-linked to advertising profiles. We disable Google signals and personalized ads for this app.
• Crash reports. If the App crashes, Firebase Crashlytics sends a diagnostic report (device model, OS version, stack trace) so we can fix bugs. Reports do not include any content the child entered.
• Device-level identifiers. The operating system reports a generic device model and OS version to our servers when the App makes a network request. This is standard for any mobile app.

2. How we use information

• To let the child resume reading and keep their progress and unlocked rewards.
• To deliver illustrations, narration audio, and coloring pages from our servers.
• To unlock premium content for active subscribers.
• To debug crashes and fix bugs.
• To understand which features children enjoy so we can improve the App.

We do not use information for advertising, profiling, behavioral targeting, or any purpose unrelated to operating the App.

3. Third parties we use

The App uses the following third-party services, each chosen because they meet the requirements of Google Play’s Designed for Families program and Apple’s Kids Category guidelines:

• Google Firebase (Authentication, Firestore, Cloud Storage, Cloud Functions, Analytics, Crashlytics, Remote Config) — operated by Google LLC. firebase.google.com/support/privacy
• Google Play Billing — processes subscription purchases on Android. We never see payment information.
• Apple StoreKit — processes subscription purchases on iOS. We never see payment information.

The App also uses server-side AI services (Google Vertex AI for illustrations, ElevenLabs for narration audio) to generate book content. These services receive only the text prompts our authoring team submits — no child data is ever sent to them.

We do not integrate any advertising SDKs, analytics platforms outside Google Firebase, social network SDKs, or behavioral retargeting tools.

4. Parental rights

Parents and legal guardians have the right to:

• Review the personal information we have collected from their child.
• Request that we delete their child’s information.
• Refuse to permit further collection or use of their child’s information.
• Cancel a subscription at any time through Google Play or the App Store.

To exercise any of these rights, contact us at DevelopByShwartz@gmail.com. We respond within 30 days. Because anonymous Firebase IDs are random, we may ask you to confirm details about the device or subscription so we can identify the correct account.

5. Data retention and deletion

We retain reading progress and reward data for as long as the App is installed and in use, or until a parent requests deletion. Crash and analytics events are retained for up to 14 months on Firebase’s default schedule and then automatically deleted. When a parent requests deletion, we remove the child’s Firestore records and revoke the anonymous Firebase Authentication account.

6. Security

All network traffic between the App and our servers uses HTTPS / TLS. Firestore and Cloud Storage access is restricted by server-enforced security rules that limit each user to their own data. Administrative access to our backend is gated by Google Sign-In plus a custom “admin” claim and is limited to our authoring team. We do not store payment card information.

7. International transfers

Our servers run on Google Cloud Platform and may store data in regions outside your country of residence. Google Cloud is certified under standard contractual clauses and adequacy frameworks that protect data transfers from the EU and the United Kingdom.

8. Changes to this policy

We may update this policy. If we make a material change in how we handle children’s information, we will obtain renewed parental consent where required by law and we will update the “effective date” at the top of this page. Continued use of the App after the effective date constitutes acceptance of the updated policy.
