This privacy policy explains which personal data the app Estate Trader (iOS and Android, “the App”) processes, for what purposes, and which rights you have. The App works without an account and without registration: you do not need to provide your name or email address to play. The App keeps your games on your device; for the rankings, the league and clubs it registers with our server under an anonymous player ID.

2. Summary
- The App registers with our server in Germany under a random player ID. Reports to our server are only linked to this ID, not to your name or email address.
- For the rankings, the App sends the moves of a ranked game (daily city, weekly season) to our server, which replays them and stores them with the result. Other players see your rank and profit under a name derived from your player ID (for example “Lindner 42”); a nickname you choose is only shown with the Trader pack.
- The weekly league, clubs and medals are based on these results. Club members see each other with name, rank and points.
- To improve the game, the App reports gameplay events (start and end of a session, games, rounds, scenarios, licence ranks, play time) under your player ID to our server.
- Purchases are handled by Apple or Google; we use RevenueCat to manage them. RevenueCat receives your player ID. The App also reports each purchase (item, price, time) to our server for statistics.
- The App shows ads from Google AdMob: a full-screen ad after every second finished game and optional reward videos. Personalised advertising only takes place with your consent. The purchases “Ad-free” and “Trader pack” switch the ads off.
- To fix crashes and errors, we use the error reporting service Sentry.
3. Player ID and nickname
On first start, the App registers with our server. The server creates a random player ID and a secret key; only a hash of the key is stored on the server. The App sends the key with every request so that your games and ranking entries are assigned to your player profile. The ID is not derived from your name, email address or device identifiers.
When registering and with its requests, the App transmits: app language, platform (iOS, Android or web) and app version, and later your licence rank in the game. The server notes on which days the App was in contact (for the number of players per day).
You can enter a nickname. It is stored with your player ID, but only shown to other players if you own the Trader pack; otherwise everyone, you included, sees the name derived from your player ID. Please do not use your real name.
Legal basis: Art. 6(1)(b) GDPR (providing the rankings of the App).
4. Ranked games, league and clubs
In the daily city and the weekly season, every player plays the same city. When you start a ranked game, the App reports the start to our server, which reserves the attempt. When you finish it, the App sends its moves (purchases, sales, rents, loans, card decisions and the like within the game), the season and the rules version. The server replays the game, stores the moves compressed together with the result (profit, net worth, return, points, rounds) and ranks it; it counts your attempts per season.
Other players see your rank, profit, return, licence rank and club under the name derived from your player ID or, with the Trader pack, under your nickname; your own entry is marked for you. Later, the winners’ games of a finished season may be shown as a replay to other players.
Weekly league: with your first ranked result of a week, the server places you in a league group with other players and computer opponents and adds up your points of the week; at the end of the week it works out your rank, promotion or relegation. Places 1–3 of a daily city, weekly season or league group earn a medal, which is stored with your player ID.
Clubs: you can found a club (name of your choice) or join one with its code. The server stores the club, its members and roles (founder, member) and the time of joining. Members see the club’s members with their names, licence ranks and points; the club name is shown next to your name on the leaderboards. A founder can remove members; you can leave a club at any time.
Legal basis: Art. 6(1)(b) GDPR (ranking feature of the App).
5. Gameplay events
So that we can see where the game is too hard or too long and improve it, the App notes certain events while you play and sends them to our server: start and end of a session (session number and duration), start and end of a game (mode, scenario, result), finished rounds, completed scenarios with their stars and licence rank-ups, each with the time, the minutes since the App was installed, your play time so far and the app version. Until they are sent, the App keeps them on your device (at most 500).
The events are only linked to your random player ID, not to your name, email address or device identifiers. We only evaluate them in aggregated form (for example how many new players finish the first scenario and how long that takes).
Legal basis: Art. 6(1)(f) GDPR (our legitimate interest in improving the App).
6. Purchases
Purchases are made through Apple (App Store) or Google (Google Play); we do not receive your payment details. In the browser version, purchases are only simulated and no payment takes place. Nothing that helps in a ranked game can be bought.
The App reports each purchase (item, price, time, whether it was simulated) with your player ID to our server for statistics. Nothing is granted on the server based on these reports.
Legal basis: Art. 6(1)(f) GDPR (our legitimate interest in improving the shop of the App).
7. Purchases
In-app purchases are processed by Apple (App Store) or Google (Google Play). We do not receive your payment details. The privacy policies of Apple and Google apply.
To manage purchases we use RevenueCat (RevenueCat, Inc., USA). The App passes RevenueCat your player ID, the purchase receipts from Apple/Google and device and app information. RevenueCat informs our server about purchases; we store these messages with your player ID so that purchases such as “Ad-free” or the “Trader pack” can be assigned to your player profile and restored (the Trader pack, for example, shows your nickname on the leaderboards). We do not pass any name to RevenueCat. More information: RevenueCat privacy policy.
Legal basis: Art. 6(1)(b) GDPR (fulfilling the purchase) and Art. 6(1)(c) GDPR (statutory retention obligations).
8. Advertising (Google AdMob)
The App shows a full-screen ad after every second finished game (not after the introduction and the first scenarios) and optional reward videos: you choose whether to watch one. Ads never help in a ranked game. After the purchase “Ad-free” or the “Trader pack”, the App shows no ads and grants rewards right away. Ads are delivered by Google AdMob (Google Ireland Limited, Gordon House, Barrow Street, Dublin 4, Ireland).
The App asks for your consent via Google’s consent form; on iOS, Apple’s tracking request is also shown. Only with your consent may Google use the advertising ID (IDFA or Google Advertising ID) and other data to show personalised ads. Without consent, Google only shows non-personalised ads; even then Google processes data such as IP address, device information and interactions with the ad to deliver ads, prevent fraud and measure ads. You can change your choice in the device settings (tracking/advertising ID). More information: How Google uses data from apps, Google privacy policy.
Legal basis: Art. 6(1)(a) GDPR and § 25(1) TDDDG (consent) for personalised ads, otherwise Art. 6(1)(f) GDPR (financing the free version).
9. Error reports (Sentry)
If the App or our server encounters an error, an error report is sent to Sentry (Functional Software, Inc., USA). It contains the technical error description, the app version, platform, operating system and device type and, for server errors, the requested address. We do not send names, nicknames or profile details. We use the reports exclusively to find and fix errors. More information: Sentry privacy policy.
Legal basis: Art. 6(1)(f) GDPR (stable and secure operation of the App).
10. Server, hosting and log files
The App communicates with our server api.estate-trader.paul-stelzer.de. Server and database run at IONOS SE (Elgendorfer Str. 57, 56410 Montabaur) in a data centre in Germany; IONOS processes the data on our behalf (Art. 28 GDPR). When the App accesses the server, the web server records technical access data (IP address, time, requested address, status code, app/browser identifier) in log files. These log files are rotated automatically and deleted after a short time. In addition, we use the IP address briefly in memory to limit excessive requests (rate limiting); it is not stored in our database.
Legal basis: Art. 6(1)(f) GDPR (security and operation of the server).
11. Data on your device
The App stores your games (including a paused game and ranked results not sent yet), your progress (licence rank, scenarios, achievements), your settings (language, map style), your purchases, purchase reports not sent yet, gameplay events not sent yet, your player ID with its key, a copy of your player profile, where you came from when you opened the App through a shared link, and when you last saw an ad locally on your device. This data is deleted when you uninstall the App. The App also uses the device functions for sharing (system share dialog), store ratings (rating dialog of Apple/Google) and checking for updates (query of the store version).
12. Contact
If you contact us by email or via the support page, we process your message and your contact details to answer your request. Legal basis: Art. 6(1)(b) or (f) GDPR.
13. Storage period
- Player profile (player ID, nickname, language, platform, app version, licence rank, purchases), ranked games, ranking entries, league entries, medals, club memberships, days of contact and purchase reports on our server: as long as we need them for the rankings, league, clubs and statistics; player profiles without ranked game, purchase or club are deleted after 30 days. Gameplay events are deleted after one year. On request we delete all data stored for your player ID (section 15).
- Purchase data at RevenueCat, Apple and Google: according to their privacy policies and the statutory retention periods.
- Data on your device: until you uninstall the App.
14. Recipients and transfers to third countries
We only pass data to the service providers named in this policy (IONOS, RevenueCat, Sentry, Apple, Google). RevenueCat and Sentry are based in the USA. Transfers take place on the basis of the EU Standard Contractual Clauses or, where the provider is certified, the EU-U.S. Data Privacy Framework (adequacy decision of the European Commission of 10 July 2023). We do not sell data.
15. Your rights
You have the right to access (Art. 15 GDPR), rectification (Art. 16), erasure (Art. 17), restriction of processing (Art. 18), data portability (Art. 20) and to withdraw consent at any time with effect for the future (Art. 7(3)).
Right to object (Art. 21 GDPR): Where we process data on the basis of legitimate interests (Art. 6(1)(f) GDPR), you can object to this processing at any time for reasons arising from your particular situation.
To exercise your rights, write to support@innomobile.de. Please include your player ID. As your data is not linked to anything else, we can only find it with this ID; we will then delete your player profile, your ranked games, ranking, league and club entries, medals, gameplay events and purchase reports.
You also have the right to lodge a complaint with a data protection supervisory authority, for example the authority responsible for us: Der Landesbeauftragte für Datenschutz und Informationsfreiheit Mecklenburg-Vorpommern, Werderstraße 74a, 19055 Schwerin, Germany.
16. Changes
We adapt this privacy policy when the App or the legal situation changes. The current version is always available on this page.
