Privacy first
Privacy policy
Effective date: August 24, 2026. Magical Colors is made for children and families. The child-facing library has no advertising, child profiles, or requests for a child's personal information.
Website activity
When first-party measurement is enabled, the website may count a visit, a printable opened, a download click, or a completed custom-book export. It uses fixed page identifiers and broad page types, never search words, names, artwork, precise location, or child information. Optional measurement is skipped for Global Privacy Control or Do Not Track.
How counts are protected
Firebase provides authentication, App Check abuse protection, server functions, and database processing. Public counts appear only as rounded group totals after a privacy threshold. Raw events are configured to expire after 90 days. Google may process technical request and browser signals to operate these services; Magical Colors does not copy them into its activity database or use them for advertising or child profiles.
Website accounts
You may optionally sign in with Google. Magical Colors does not copy your Google email or display name into the activity database. Account data can be deleted through support or the account page.
Downloads
A small set of popular starter PDFs is public for search and quick sampling. The full page library is selected inside the member studio. When the first-party service is enabled, a download click may create a pseudonymous Firebase access identifier for a non-blocking daily allowance and abuse protection.
Make a book
Page choices and the completed PDF stay in the browser. Optional aggregate measurement includes only page count, paper, and orientation. Selected page IDs and order are not uploaded with the generated PDF.
App privacy
The Magical Colors app saves coloring progress locally on the device. The child experience has no accounts, ads, analytics, web browsing, or third-party tracking. Local artwork is not sent to this website.
Questions and deletion
For a privacy question or account-data deletion request, contact danghoang.jp@icloud.com. Please write from the account email for an account request, and never include a child's personal information.
