This policy explains what information the Robot Dev Tycoon game ("the game") uses, why, and the choices you have. The game is made by Walking Library ("we", "us"). You can reach us at info@walking-library.com.
The short version
- You don't need an account to play, and we don't run servers that store information about you.
- Your company, settings and purchases are saved on your phone.
- The game uses Google services to show ads you choose to watch, to understand how the game is played, and to sell items in the shop. Those services collect some information from your device, as described below.
1. Information saved on your phone
The game saves your progress, your settings and what you have bought on your phone. It is not sent to us. Uninstalling the game deletes it.
2. Ads: Google AdMob
The game shows an ad only when you choose to watch one for a reward. Ads are served by Google AdMob, which collects information from your device to show and measure ads, prevent fraud and, where you allow it, personalize ads. This information includes your device's advertising identifier, IP address, approximate location derived from it, device and app details, and how you interact with ads.
Where the law requires it, such as in the European Economic Area, the UK and Switzerland, the game asks for your choices about ads before any ad is shown, using Google's consent tool. You can change your answer at any time: open Settings in the game and tap the shield.
You can also reset your advertising identifier or opt out of personalized ads in your phone's settings.

3. Game statistics: Google Analytics for Firebase
To understand how the game is played and make it better, the game uses Google Analytics for Firebase. It records events such as starting and finishing the tutorial, building a robot, finishing research, a team member leaving, tokens earned and spent, and purchases, along with an app instance identifier, device model, operating system, app version, country and approximate location. It does not record your name, email or contacts.
Where the law requires your consent, these statistics are collected only if you allow it in the same choices about ads and privacy.
Google Analytics keeps this information for at most 14 months.
4. Purchases
Purchases in the game are handled by Google Play on Android and by the App Store on iPhone and iPad. We never see your payment details. The store tells the game what you bought so the game can give it to you, and lets the game check your purchases again when it starts or when you tap Restore purchases.
5. Sharing
We don't sell your information. The information described above goes to Google, which provides the services named in this policy, under Google's own privacy policy: policies.google.com/privacy. Google may process it in the United States and other countries.
6. Children
The game is not directed at children under 13, and we don't knowingly collect personal information from them. If you believe a child under 13 has given us personal information, write to us and we will delete it.
7. Security
Information the game sends to Google travels over encrypted connections.
8. Your rights
Depending on where you live, you may have the right to access, correct or delete information about you, to object to its use, or to withdraw your consent. We don't hold information that identifies you by name, but write to info@walking-library.com and we will help, including with requests about information held by the services above.
9. Changes to this policy
If this policy changes, we will post the new version on this page and update the date at the top.
