Privacy Policy

Last updated: August 8, 2026

Baby Book Tracker does not sell your family reading data or use it for advertising. The app works without a Baby Book Tracker account, and its core library stays on your device unless you choose to use iCloud sync.

Your data stays on your device

Everything you put into the app (baby profiles, books, reading logs) is stored locally on your device by default. No Baby Book Tracker account is needed.

No ads or behavioral profiling

Baby Book Tracker does not use your family reading data for advertising or behavioral profiling. The app includes diagnostic error reporting and purchase infrastructure, described below, to keep the app reliable and manage optional purchases.

Optional iCloud sync

If you enable iCloud sync, your library data and selected images are saved to your private iCloud/CloudKit database so you can sync or share your library through Apple's services. iCloud sync is optional and can remain off.

Android notification signup

If you submit the Android notification form on this website, we send your email address, the product name, and the form context to our notification endpoint at langi.app so we can contact you about the Android release. We do not use that email address for advertising.

Diagnostics and purchases

The app includes Sentry for crash and error reporting. When diagnostic events are sent, Sentry processes technical information and error context needed to identify and fix reliability issues. If you make or restore an in-app purchase, Apple and RevenueCat process purchase and entitlement information so the app can provide Full Access. These services are not used for advertising or behavioral profiling.

Website analytics

This website loads an analytics script from analytics.montalesi.dev to measure website usage. Website analytics is separate from the app and does not receive your baby profiles, library, or reading logs.
