The principle

Industrie Baron is a game for your device. It needs no account, no name, no e-mail address, no location and no advertising ID. There are no ads, no Google Analytics, no Firebase and no other analytics or advertising tools. Saved games and settings stay on your device.

Data only leaves the device in the cases listed below – and most of them only when you do something yourself.

Error and crash reports – only with your consent

If the game ended unexpectedly or errors occurred, the main menu asks on the next start whether a report may be sent ("Send report" / "Don't send"). Your choice applies from then on and can be changed under Settings → "Error reports" (Ask every time / Always send / Never send). Without consent nothing is sent.

A report contains: app and Godot version, device manufacturer and model, Android version, whether the game ended unexpectedly, and up to 20 error locations in the program code with a shortened message. It contains no saved games, no in-game names and no device identifier. Reports are deleted from the server after 90 days. We only use them to find and fix bugs.

Legal basis: Art. 6(1)(a) GDPR (consent). You can withdraw it at any time in the settings.

Performance measurement – only on request

Under Settings → "Measure performance" the game plays a fixed scene and measures frame rate, processing time and memory. Only if you then tap "Send result" are these values sent to us together with the app version, device model, Android version, screen resolution and number of processor cores. No saved games, no identifier. Deleted after 90 days.

Legal basis: Art. 6(1)(a) GDPR (you send it yourself).

Purchases via Google Play

You buy the full version and the vehicle packs via Google Play. Google handles the purchase; we receive neither your name nor your payment details from Google.

To verify a purchase, the app sends the purchase receipt (product and Google purchase token) to our server. The server asks Google whether the purchase is valid and stores in the purchase log: product, Google order number, state (valid/cancelled), time and a checksum of the purchase token – not the token itself. We keep the purchase log as long as needed for proof and tax obligations.

Legal basis: Art. 6(1)(b) GDPR (performance of the purchase contract) and (c) (retention obligations).

Gift and tester codes

Codes are checked offline in the game. Nothing is sent when redeeming. Your device notes which codes were redeemed.

Google Play Games

If Google Play Games is active on your device, the game reports unlocked achievements, your weekly map score (company value after 10 game years, for the leaderboard) and – only when you tap "Save to cloud" – a cloud save to Google Play Games. Google's privacy policy applies there; anyone viewing the leaderboard sees your Play Games profile (name, picture). We ourselves receive no data from this.

Legal basis: Art. 6(1)(b) GDPR (game features you use).

IP addresses

Whenever the app connects to our server (report, measurement, purchase check) the server sees your IP address. We do not store it. To limit requests, a salted, shortened hash is formed from the address; the counter only applies to the current day and is overwritten afterwards. The usual server logs of the hosting provider remain unaffected.

Legal basis: Art. 6(1)(f) GDPR (protection against abuse, secure operation).

Who else sees data – complete list

• IONOS SE, Elgendorfer Str. 57, 56410 Montabaur, Germany. Operates the server at mtcteam.de and sees the usual server logs. A data processing agreement under Art. 28 GDPR is in place.
• Google Ireland Ltd. – as the distribution channel (Google Play), for purchases (Google Play Billing) and, if active, for Google Play Games. For purchases our server sends the receipt to Google for verification.

The list ends here. There are no ads in this game.

Retention

• Saved games, settings, redeemed codes: only on your device, until you delete the app
• Error reports and measurements on the server: 90 days
• Purchase log: as long as needed for proof and tax obligations

Your rights

You have the right of access, rectification, erasure, restriction of processing, data portability and objection (Art. 15–21 GDPR) and the right to lodge a complaint with a supervisory authority (Art. 77 GDPR). Write to us at info@mtcteam.de. To have data deleted, send an e-mail to info@mtcteam.de; as we keep no accounts, please include details that let us find the entries (e.g. the Google order number of a purchase). We delete within 30 days.

Children

The game is suitable for all ages and does not ask for personal data.

Changes

If what the game sends changes, this policy is updated beforehand.
