Thank you for choosing to be part of our community by playing Quantum Chain (also referred to as "Chain Reaction"). We are committed to protecting your personal information and your right to privacy. If you have any questions or concerns about this privacy notice, or our practices with regards to your personal information, please contact us.
When you use our mobile application, as the case may be (the "App"), and more generally, use any of our services (the "Services", which include the App), we appreciate that you are trusting us with your personal information. We take your privacy very seriously. In this privacy notice, we seek to explain to you in the clearest way possible what information we collect, how we use it and what rights you have in relation to it.
Please read this privacy notice carefully as it will help you understand what we do with the information that we collect.
We do not actively collect any personal information (such as your name, email address, or phone number) unless you directly contact us for support or feedback.
Some information — such as your Internet Protocol (IP) address and/or browser and device characteristics — is collected automatically when you visit our App. This information does not reveal your specific identity (like your name or contact information) but may include device and usage information, such as your IP address, browser and device characteristics, operating system, language preferences, referring URLs, device name, country, location, information about how and when you use our App and other technical information.
If you use our App, we also may collect the following information:
The App does use third-party services that may collect information used to identify you.
Link to privacy policies of third-party service providers used by the app:
We use personal information collected via our App for a variety of business purposes described below:
We only share information with the following categories of third parties:
We may use cookies and similar tracking technologies (like web beacons and pixels) to access or store information. Specific information about how we use such technologies and how you can refuse certain cookies is set out in the respective privacy policies of our third-party service providers.
We keep your information for as long as necessary to fulfill the purposes outlined in this privacy notice unless otherwise required by law.
We have implemented appropriate technical and organizational security measures designed to protect the security of any personal information we process. However, despite our safeguards and efforts to secure your information, no electronic transmission over the Internet or information storage technology can be guaranteed to be 100% secure.
We do not knowingly solicit data from or market to children under 13 years of age. By using the App, you represent that you are at least 13 or that you are the parent or guardian of such a minor and consent to such minor dependent’s use of the App. If we learn that personal information from users less than 13 years of age has been collected, we will deactivate the account and take reasonable measures to promptly delete such data from our records.
In some regions (like the EEA, UK, and California), you have certain rights under applicable data protection laws. These may include the right (i) to request access and obtain a copy of your personal information, (ii) to request rectification or erasure; (iii) to restrict the processing of your personal information; and (iv) if applicable, to data portability.
Most web browsers and some mobile operating systems and mobile applications include a Do-Not-Track ("DNT") feature or setting you can activate to signal your privacy preference not to have data about your online browsing activities monitored and collected. At this stage no uniform technology standard for recognizing and implementing DNT signals has been finalized. As such, we do not currently respond to DNT browser signals or any other mechanism that automatically communicates your choice not to be tracked online.
Yes, we will update this notice as necessary to stay compliant with relevant laws. We may update this privacy notice from time to time. The updated version will be indicated by an updated "Revised" date and the updated version will be effective as soon as it is accessible.
If you have questions or comments about this notice, you may contact us via our developer contact channels provided on the Google Play Store or Apple App Store.
