Privacy Policy – Carrier Wars
for the app "Carrier Wars"
This is a non-binding English translation for your convenience. The German version of this privacy policy is legally binding.
Last updated: November 2026
In short: the app sends your game results (highest level completed, ships sunk, islands captured) together with your country and a random identifier to our server so that there is a leaderboard. No name, email address or location is collected for this. Only if you use the feedback form do we receive your message and – if you enter it – your email address. There is no tracking and no advertising.
1. Controller
The controller within the meaning of the General Data Protection Regulation (GDPR) is:
2. Game Results and Leaderboard
Carrier Wars requires no user account. So that we can keep a leaderboard and develop the game further, the app sends the following to our server carrierwars.kainzner.net when it starts and after every finished level:
- a random identifier that the app creates itself the first time it is used; it is not linked to your name or to any device or advertising ID,
- the platform (iOS) and the app version,
- the country code from your device's region setting (for example "AT"); your location is not accessed for this,
- the highest level completed, the number of ships sunk and the number of islands captured.
The transfer is encrypted with HTTPS. On receipt, the server technically stores the IP address, the time and the requested address in log files; these are deleted after 31 days. The game results themselves are kept for as long as this service exists. In the app's leaderboard they are visible to all players with rank and country flag, without the identifier. They are not passed on to third parties and are not used for advertising or tracking. The server is operated on our behalf by netcup GmbH, Daimlerstraße 25, 76185 Karlsruhe, Germany, as hosting and infrastructure provider. The data is stored in a data centre in Vienna (Austria).
The legal basis is Art. 6(1)(f) GDPR (legitimate interest in a leaderboard and in developing the game further). If you delete the app, no more data is sent.
3. Local Storage
The app stores on your device what it needs for playing: the levels you completed, which level introductions you have already seen, your game statistics (ships sunk, islands captured), the random identifier from section 2 and the sound setting. Of these, the app transmits only the details listed in section 2. The time-of-day picture in the title bar uses the country of your App Store; your location is not accessed. If you delete the app, this data is deleted with it. Whether it is part of your own device backups depends on the settings on your device.
4. No Tracking, No Ads, No Cookies
The app uses no tracking, third-party analytics services, advertising, advertising IDs, cookies or comparable services whatsoever. No user profiles are created. The app contains no in-app purchases.
5. App Store
Apple's privacy policy applies to downloading the app. Apple provides developers with aggregated download figures; we receive crash reports only if you allowed this in your device settings.
6. Feedback Form and Email
The app's settings contain a feedback form. When you send it, the app transmits your message, your email address if you enter one, as well as the app version, iOS version, device type (for example "iPhone17,2"), the country code and the random identifier from section 2 to carrierwars.kainzner.net. The server stores these details together with your IP address (to protect against abuse) and forwards them to us by email. If you email us of your own accord, we process your email address and details in the same way in order to answer your enquiry. We delete feedback once it has been dealt with and is no longer needed. The legal basis is Art. 6(1)(f) GDPR (legitimate interest in answering enquiries and in improving the game).
7. Encryption
The transfer to our server uses the operating system's HTTPS encryption. The app uses no encryption of its own and no export-restricted or sanctioned encryption.
8. Your Rights as a Data Subject
Insofar as we process data about you, you have the following rights under the GDPR, subject to the statutory requirements:
- Right of access (Art. 15 GDPR)
- Right to rectification (Art. 16 GDPR)
- Right to erasure (Art. 17 GDPR)
- Right to restriction of processing (Art. 18 GDPR)
- Right to data portability (Art. 20 GDPR)
- Right to object to processing (Art. 21 GDPR)
An informal email is sufficient to exercise these rights: christoph@kainzner.net. Because game results are linked only to a random identifier, we can only match them to you if you give us details that let us find your entry, for example country, platform and your current values.
9. Right to Lodge a Complaint
You have the right to lodge a complaint with a data protection supervisory authority. The authority responsible for us in Austria is:
Barichgasse 40–42, 1030 Vienna
Email: dsb@dsb.gv.at
Website: https://www.dsb.gv.at
10. Changes to this Privacy Policy
We reserve the right to adapt this privacy policy to changed legal requirements or changes to the app. The current version available on this page applies.
