Privacy Policy

What we collect and where it lives

Hue Check does not collect or transmit your personal data. All of your data is stored on your device using Apple's UserDefaults (local storage). Nothing is uploaded to any server, and we have no user accounts, no registration, and no sign-in.

Colour samples captured from the camera are processed on-device using Apple's AVFoundation framework. No camera frames are stored or uploaded.

Advertising and third-party data (free tier)

The free version of Hue Check shows ads served by Google AdMob. When you first open the app, Apple's App Tracking Transparency (ATT) prompt asks for your permission before any advertising identifier is used.

If you allow tracking: AdMob may use your device's advertising identifier (IDFA) to show personalised ads. This identifier is managed and stored by Google, not by us.

If you decline tracking: Hue Check tells AdMob to serve non-personalised ads only. No device identifier is passed to Google in this case.

You can change this setting at any time in iPhone Settings under Privacy and Security, then Tracking.

For more on how Google handles advertising data, see Google's Privacy Policy.

Hue Check Pro removes all advertising. No AdMob activity occurs once Pro is unlocked.

In-App Purchases

Hue Check Pro is a one-time, non-consumable purchase handled entirely by Apple's App Store and StoreKit 2. We do not receive or store your payment information. Apple manages the transaction and issues us only a confirmation that the purchase was completed.

You can restore your purchase at any time using the "Restore Purchases" option in the app.

Data we do NOT collect

To be clear, Hue Check does not collect any of the following:

Your name, email address, phone number, or physical address. Your payment card details. Your location. Your contacts. Your health or fitness data. Your browsing or search history. Any analytics or usage events (no analytics SDK is integrated).

Children

Hue Check is not directed at children under 13, and we do not knowingly collect any data from children.

Changes to this policy

If we update this policy, the new version will be published at this URL and the "Last updated" date will change. For significant changes, we will include a notice in the next app update.
