This policy explains what data the Android game IRON LINE: Tower Defense ("the game") handles. We keep it as small as possible: there is no account, no e-mail address and no advertising profile built by us.
DATA STORED ONLY ON YOUR DEVICE
Your progress (missions, stars, War Credits, upgrades, settings, purchases already made) is stored in the game's local storage on your device. It never leaves the device unless you use the online modes below. Uninstalling the game or clearing its data deletes it.
ONLINE MODES (DAILY FRONT, ENDLESS FRONT, LEADERBOARDS)
These modes are optional and need an internet connection. When you open them the game creates an anonymous profile on our server (hosted by Supabase). The profile contains: a random anonymous identifier (no name, e-mail, phone number or device ID); a callsign - a nickname you can change in Settings (default "Commander NNNN"), which is shown to other players on leaderboards, so do not put personal information in it; your scores, the wave or day you reached, a record of the moves of each ranked run (used only to verify the result), and the dates of your attempts.
We use this data only to run the leaderboards, check results and prevent cheating. We do not sell it or use it for advertising. You can delete the profile, your scores and attempts at any time in Settings > DELETE ONLINE PROFILE.
ADVERTISING (GOOGLE ADMOB)
The game offers optional rewarded video ads that you choose to watch. Ads are provided by Google AdMob. AdMob may collect and use device and advertising identifiers (such as the Android Advertising ID), IP address, approximate location, and information about ad interactions, to serve and measure ads and to prevent fraud. In the European Economic Area, the United Kingdom and Switzerland the game asks for your consent through Google's consent message (UMP) before personalized ads; you can change your choice in Settings. Details: https://policies.google.com/technologies/ads and https://support.google.com/admob/answer/6128543
The game is not designed for children under 13 and ads are limited to the "Parental Guidance" content rating.
PURCHASES (GOOGLE PLAY BILLING)
In-app purchases (Commander License, War Credit packs) are processed by Google Play. We do not receive your payment card or payment details. We only receive confirmation that a purchase was made so we can unlock it. Purchases can be restored on a new device through Google Play.
WHAT WE DO NOT DO
We do not use analytics or tracking SDKs of our own, do not collect your contacts, photos, microphone, camera or precise location, and do not share data with third parties other than the service providers named here (Google for ads and purchases, Supabase for hosting the online modes).
RETENTION AND YOUR RIGHTS
Online profile data is kept until you delete it in Settings or ask us to delete it. Under the GDPR you have the right to access, rectify, erase and port your data and to object to its processing; since the profile is anonymous we may need the callsign and approximate dates to find it. Contact: support@kyrsoftstudios.com. You can also complain to your data protection authority (in Slovakia: Urad na ochranu osobnych udajov SR).
CHILDREN
The game is not directed to children under 13. We do not knowingly collect personal data from children. If you believe a child has provided a callsign with personal data, contact us and we will remove it.
CHANGES
We may update this policy. The date above shows the latest version; material changes will be described in the game's update notes.
