Under the brand “grubenhund games” I develop and publish games for smartphones and tablets. I am not required to appoint a data protection officer; if you have questions, write to me directly.

2. Scope

This policy covers the game “Doggo Dive”. The version for all games is at games.grubenhund.com/en/privacy.

What happens when you visit this website (games.grubenhund.com) is described in the section “Visiting this website”. The dog training website grubenhund.com has its own privacy policy (in German).

3. In short

  • You don't need to register – no name, no password.
  • Your progress is stored on your device.
  • Your progress is also backed up under a random, anonymous ID in a data center in Frankfurt, Germany.
  • We use no analytics or tracking tools of our own.
  • Ads are served by Google AdMob – personalized only with your consent.

4. Progress on your device

The game stores progress, settings and unlocked content locally on your device. It also keeps an optional player name for friend duels and the names of your duel friends – both are part of your progress and included in the cloud backup –, a random install ID and a short error log. The install ID and error log stay on your device. The game automatically backs up a copy of your progress to the cloud (see below). Legal basis: Art. 6(1)(b) GDPR (providing the game) and § 25(2) no. 2 TDDDG (storage on the device that is strictly necessary).

Note on device backups: on Android, the backup in your Google account may back up the game data and restore it after a reinstall; Google's privacy terms apply and we do not receive this data. On iPhone, the save is excluded from iCloud Backup.

5. Sharing

If you share a save code or a duel invite, you choose the recipient and the app yourself. We do not receive this data.

The save code contains your entire progress including your player name and install ID; the duel invite contains your player name.

6. Cloud backup of your progress

So your progress survives a new phone or a reinstall, the app backs up your progress automatically – at launch, shortly after changes and when you leave the app. For this the app creates an anonymous account (random user ID, no e-mail, no name), but only once you have finished the first level.

Data: your progress (levels, stars, shells, collection, in-game settings, your player name and the names and results of your duel friends – without the install ID), a small summary (level, stars, shells, time), the device type (iOS or Android), a version number and the game and language on the account. Your IP address technically appears in the server logs. In Settings you will find a recovery code to move your progress to another device; the server only keeps a one-way hash of it.

Processor: Supabase, Inc. (USA) as processor under Art. 28 GDPR; the data is stored on servers in Frankfurt, Germany (EU). Legal basis: Art. 6(1)(b) GDPR (providing the game including backup).

Turning it off and retention: you can turn the backup off under Settings → “Cloud save” and delete your cloud data there. Otherwise the data is kept until you delete it or ask us to; accounts unused for 24 months are deleted automatically. See Delete data.

7. Ads (Google AdMob)

Doggo Dive is free to play and is funded by optional rewarded videos. When you choose to watch a video (one life back or extra moves), Google AdMob shows an ad – a service of Google Ireland Limited, Gordon House, Barrow Street, Dublin 4, Ireland. There is no other advertising.

Where Google requires consent (e.g. in the EEA, the UK and Switzerland), the app first asks through Google's consent form whether personalized ads are allowed; without consent only non-personalized ads are shown. On iPhone, iOS then asks whether the app may use the advertising identifier (IDFA). The form appears at the earliest on your second launch or the first time you want to watch a video. Where consent is required, you change your choice under Settings → “Ad privacy settings” (the entry appears once the consent form has run); you change the tracking permission in the iOS Settings.

Google processes, among other things, device and advertising IDs, IP address, approximate location, ad interactions and diagnostics (Google Privacy Policy). Legal basis: Art. 6(1)(a) GDPR (consent), or (f) for non-personalized ads. Transfers to the USA are based on the EU-US Data Privacy Framework or Standard Contractual Clauses.

8. Children and teens

The game is not specifically directed at children under 13. It contains no purchases.

9. Reminders and rating

If you agree (a question in the game from level 6, then iOS or Android), the app schedules reminders on your device: when your lives are full, for the daily gift at 6 pm and 24 hours before an event you take part in ends. This happens only on the device; there is no push server and no device token with us. Turn off: Settings → “Reminders”.

From level 8, after a 3-star win the app may open Apple's or Google's rating dialog at most every 120 days. The system decides whether it appears; we receive no data from it.

10. Visiting this website

This website (games.grubenhund.com) sets no cookies, uses no analytics or tracking tools and embeds no third-party content; fonts, images and videos come from the same server. Links to the App Store, Google Play or other websites only transfer data to those providers once you click them.

When you open a page, the host processes technically necessary data in server logs: IP address, date and time, requested address, amount of data transferred, browser and operating system. This is required to deliver the website, detect attacks and fix errors (Art. 6(1)(f) GDPR; legitimate interest in secure and reliable operation). The site is hosted by Vercel Inc., 650 California St, San Francisco, CA 94108, USA, as processor; transfers to the USA are covered by the EU Standard Contractual Clauses and Vercel's certification under the EU-US Data Privacy Framework. Logs are kept only as long as needed for operation, security and troubleshooting, usually no longer than 30 days.

If you send me an e-mail, I process your details in order to reply (Art. 6(1)(b) or (f) GDPR).

11. Recipients and service providers

  • Supabase, Inc. (USA) – cloud storage and database, servers in Frankfurt, Germany (processor)
  • Google Ireland Limited – advertising via AdMob (separate or joint controllership under Google's terms)
  • Vercel Inc. (USA) – hosting of this website games.grubenhund.com (processor, see “Visiting this website”)

Beyond that we do not share personal data, and we never sell data.

12. Transfers outside the EU

Some service providers are based in the USA. Where data is transferred there, this is based on the EU-US Data Privacy Framework (adequacy decision of the European Commission) or EU Standard Contractual Clauses (Art. 46(2)(c) GDPR). Cloud saves are stored on servers in Frankfurt, Germany.

13. Your rights

You have the right of access (Art. 15 GDPR), rectification (Art. 16), erasure (Art. 17), restriction of processing (Art. 18), data portability (Art. 20) and objection (Art. 21), and you may withdraw consent at any time with effect for the future (Art. 7(3)). Write to info@grubenhund.com.

Right to object

Where we process data on the basis of legitimate interests (Art. 6(1)(f) GDPR), you may object to this processing at any time on grounds relating to your particular situation (Art. 21 GDPR). Write to info@grubenhund.com.

How to delete data yourself is explained under Delete data.

You may also lodge a complaint with a supervisory authority, for example the data protection authority of North Rhine-Westphalia (LDI NRW), Kavalleriestraße 2–4, 40213 Düsseldorf, Germany.

14. Changes

When a game changes – for example with new features or service providers – I update this policy. The version published here applies. If this English version differs from the German one, the German version prevails.
