Operation Halcyon is made by Cirro Studio, based in Amsterdam, the Netherlands. If you have any question about this policy or your data, email hello@cirro.studio.
Operation Halcyon does not ask for your name, email address, location, contacts or photos, and it does not require an account. Your mission progress is saved only on your own device.
When you download the game, Google Play handles the download and any purchases under Google's privacy policy. Google may share anonymous crash reports and download statistics with us so we can fix problems. These do not identify you.
If you write to us, for example to hear about the launch, we keep your email address and message only to reply to you. We never sell or share it. Ask us at any time and we will delete it.
We do not knowingly collect personal information from anyone, including children under 16.
Under the GDPR you can ask to see, correct or delete any personal data we hold about you. Email hello@cirro.studio and we will respond within 30 days. You can also complain to the Dutch data protection authority, the Autoriteit Persoonsgegevens.
If the game changes what it collects, for example by adding ads or online features, we will update this page before that version is released.
