This Privacy Policy explains how Callisto Productions ("we", "us") handles information in connection with the mobile game Cosmic Hole ("the Game"). By installing or using the Game, you agree to this Policy. The Game does not require you to create an account or provide any personal details such as your name, email, or phone number.
We do not collect personal data directly. The Game does not ask for or store your name, email, contacts, photos, or precise location.
Data collected automatically by third-party services (advertising and platform SDKs): To display ads and keep the Game running, our third-party partners may automatically collect:
device advertising identifiers (e.g., Google Advertising ID / GAID);
device and technical information (device model, operating system version, language, screen size);
IP address and approximate (country/region-level) location derived from it;
information about your interaction with ads (views, clicks) and app usage events.
Data stored locally on your device: Your game progress and settings (current level, audio/language preferences) are saved on your device only and are not transmitted to us.
The automatically collected data is used to:
show advertising, including personalized advertising where permitted;
operate, maintain, and improve the Game;
prevent fraud and abuse and ensure technical stability.
The Game shows ads through Unity LevelPlay (ironSource) mediation, which may serve ads from the following networks. Each partner processes data under its own privacy policy:
Unity Ads / Unity LevelPlay (Unity Technologies / ironSource) — https://unity.com/legal/privacy-policy and https://www.is.com/privacy-policy/
Yandex Advertising Network (Yandex) — https://yandex.com/legal/confidential/
VK Ads / myTarget (VK) — https://vk.company/en/legal/vkads_privacy/
Google Play services / Advertising ID (Google) — https://policies.google.com/privacy
These partners act as independent data controllers for the data they collect through the Game.
The Game is intended for a general audience and is not directed to children under the age of 13 (or the applicable age in your country). We do not knowingly collect personal information from children. If you believe a child has provided personal data, please contact us and we will take appropriate steps.
Advertising ID: You can reset your advertising identifier or opt out of ad personalization in your device settings (Android: Settings ▸ Google ▸ Ads).
EEA/UK (GDPR): Where required, you will be asked for consent for personalized advertising, and you may withdraw it at any time. You have rights to access, correct, or delete your data — contact the relevant ad partner above or us.
California (CCPA): You may request information about, or deletion of, personal information, and opt out of its "sale/sharing" for targeted advertising.
We do not store personal data on our own servers. Data collected by advertising partners is retained according to their respective privacy policies.
Because our advertising partners operate globally, your information may be processed in countries other than your own, with appropriate safeguards as described in their policies.
We rely on reputable third-party SDKs and standard platform protections. However, no method of transmission or storage is 100% secure.
We may update this Policy from time to time. Changes will be posted on this page with an updated effective date. Continued use of the Game after changes means you accept the revised Policy.
