Privacy Policy for Contrast Checker
Last updated: September 12, 2026
This Privacy Policy describes how Contrast Checker ("we", "our", or "the app") handles user information when you use our mobile application. We are committed to transparency and protecting your privacy.
1. Local Processing & Image Data
Our core tools operate locally on your device without sending sensitive content to external servers:
- Uploaded Screenshots & Images: When you select or upload an image to sample colors, the image is rendered locally onto your device screen using an on-device canvas. We do not transmit, upload, or store your photos or screenshots on any remote cloud servers.
- Color Palettes & Calculations: Contrast ratios, auto-adjust calculations, and hex values are computed in real time entirely within your device memory.
2. Third-Party Services, Analytics & Advertising
To support ongoing development and understand app usage, the app integrates third-party services provided by Google LLC. These services collect certain data automatically:
- Google AdMob: We use AdMob to serve advertisements. AdMob may collect and process device identifiers (such as Android Advertising ID), approximate location data derived from IP addresses, and interaction metrics to serve relevant or contextual ads.
- Google Analytics for Firebase: We utilize Firebase Analytics to understand user engagement, feature usage, and retention trends. Firebase automatically collects pseudonymous identifiers, device hardware models, operating system versions, and standard in-app event interactions.
For more details on how Google processes and protects data collected through partner apps, please review How Google uses information from sites or apps that use our services and the Google Privacy Policy.
3. Data Retention and Control
- Ad Identifiers: You can reset or limit your device's Advertising ID at any time through your Android system settings (under Settings > Google > Ads).
- App Data: You can remove all locally cached preferences by clearing the app data in your device settings or by uninstalling the application.
4. Children’s Privacy
The app is intended for general design and developer audiences. We do not knowingly collect personally identifiable information from children under the age of 13.
5. Changes to This Privacy Policy
We may update this Privacy Policy to reflect changes in legal requirements, third-party SDK updates, or feature additions. Any updates will be published to this page with a revised "Last updated" date.
