This Privacy Policy describes how GemTrace ("we", "our", or "us") collects, uses, and shares information about you when you use our mobile application GemTrace ("the App").
We do not collect any personal information. The App stores your preferences (favorites, notes, purchased packs) locally on your device using SharedPreferences.
The App uses the following third-party services:
We use Google AdMob to display ads. You may see personalized ads based on your interests, or you can opt out of ad personalization through your device settings.
All user data (favorites, notes, collection progress) is stored locally on your device. We do not transmit this data to any server.
The App is suitable for all ages. We do not knowingly collect personal information from children under 13.
We may update this Privacy Policy from time to time. We will notify you of any changes by posting the new Privacy Policy on this page.
This app displays ads served through Unity LevelPlay, an ad mediation platform operated by Unity Technologies (formerly ironSource). To deliver and measure ads and to prevent fraud, the Unity LevelPlay SDK and the ad networks it works with may collect device information such as the advertising identifier (Google Advertising ID), IP address, device model, operating system version, language setting, and your interactions with ads. This information is processed by Unity and its ad network partners under their own privacy policies: Unity Privacy Policy. You can reset your advertising ID or opt out of personalized ads at any time in your device settings (Settings > Google > Ads).
