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 “Wobble Garden”. 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, no account with us.
  • Your progress is stored on your device and, if you turn on the backup, also in your private iCloud.
  • We run no servers and use no analytics or tracking tools. The app does not ask for tracking permission.
  • Ads are served by Google AdMob and are always non-personalized. Under 13, and before the game has asked for your age, there are no ads; up to 15, only videos you start yourself.
  • Your month and year of birth stay on your device and are only used to protect minors from unsuitable ads.
  • Purchases are handled by Apple; we never see payment details.
  • The app signs you in to Apple Game Center if you are signed in there; we receive no data from this.

4. Progress on your device

The app stores on your device: solved puzzles with your treats, Wobbles, tips, outfits, items and friends, completed gardens, your daily-puzzle streak, achievements, purchased packs with Apple's transaction numbers, counters and receipts of ad videos, the day of your last free tip, the daily ad-break counter, your age information (see “Children and teens”) as well as language, music, sound and vibration settings. The purpose is to keep progress, purchases and rewards, never credit anything twice and keep ads age-appropriate (Art. 6(1)(b) GDPR; for the age information (c) or (f)). Wobble Garden creates no account of its own and runs no servers of its own.

Note on device backups: if iCloud Backup on your iPhone or iPad is on, it may also back up the game data. Apple's privacy terms apply; we do not receive this data.

5. Optional backup in your iCloud

The iCloud backup starts off. Turn it on in the settings with the “iCloud backup” switch. It uses your Apple account's private CloudKit database – there is no separate game account, and we have no access to it.

It backs up your progress: puzzles and treats, Wobbles, tips, outfits, items and friends, gardens, your daily streak, achievements, purchased packs with Apple's transaction numbers, the counters and receipts of ad videos and the day of your last free tip, plus version, revision and save time. Not included are your age information, language, music, sound and vibration settings and the daily ad-break counter. A hashed reference to your iCloud account stays on the device; if you switch accounts, the backup turns itself off. If two devices have different progress, the game merges them automatically and keeps the better result of each.

Legal basis: Art. 6(1)(b) GDPR for the backup you turned on. The copy stays until you delete it; turning the backup off does not delete it. How to delete it is explained under “Delete data”. Apple's terms apply to your Apple account and iCloud.

6. Apple Game Center

At launch the app signs you in to Apple Game Center; if you are not signed in, Apple may show its sign-in screen. When you are signed in and the leaderboard and achievements are enabled for the game, it reports your total number of treats to the leaderboard and unlocked achievements to Game Center. Who can see your entry depends on your Game Center settings. We receive no data from this. Apple's privacy terms apply to Game Center.

7. In-app purchases

Purchases are handled entirely by the Apple App Store or Google Play, who are separate controllers for this. We never receive payment details. The game only receives a purchase confirmation and records in your save which content you bought, so it stays unlocked. Legal basis: Art. 6(1)(b) GDPR.

Offered are the No Ad Breaks Pack (previously “No-ads bundle”; one-time: no more ad breaks, 15 tips and Buddy's friend Goldie with a golden coat), the starter pack (one-time: 600 Wobbles, 10 tips and the bucket hat) and packs of 10 or 30 tips. Apple sets the prices for each country and shows them before you buy. The app stores which purchases were credited, with Apple's transaction numbers, on the device (and, if turned on, in the iCloud backup) so nothing is credited twice or lost. Players under 13 see no purchase button in the tip dialog.

8. Ads (Google AdMob) and privacy choices

Wobble Garden shows ads via Google AdMob, a service of Google Ireland Limited, Gordon House, Barrow Street, Dublin 4, Ireland. How many depends on your age (see “Children and teens”):

  • Before the game has asked for your age, and under 13: no ads. The ad service is not started, no ads are requested and no videos are offered.
  • 13 to 15 and “Rather not say”: only optional videos that you start yourself – for a tip, to skip a level, or for free Wobbles (up to five times a day). No ad breaks. The ad service only starts with your first video; ads are requested as child-directed.
  • 16 and 17: optional videos and short, announced ad breaks after wins, requested as teen-directed.
  • 18 and older: optional videos and ad breaks; Google's consent form where Google requires it.

Ad breaks appear after the tenth solved level at the earliest, then at most after every third new win, at least two minutes apart, no more than six per session and twelve per day. The No Ad Breaks Pack removes them; the optional videos stay available.

For all age groups, the app only requests non-personalized ads, disables personalization and the publisher first-party ID, and caps ad content at Google's “G” rating (all audiences). Players under 18 are flagged to Google as under the age of consent. The app does not ask for tracking permission (App Tracking Transparency) or your precise location. Non-personalized is not anonymous: Google may process IP address, approximate location, device information, ad interactions and diagnostics for delivery, fraud prevention and reporting (Google Privacy Policy).

Consent: for adults, the app shows Google's consent form where Google requires it (e.g. in the EU); ads are only requested when it allows. Adults can change or withdraw their choice under “Ad privacy” in the settings. Legal basis: processing that requires consent relies on Art. 6(1)(a) GDPR and, where applicable, § 25(1) TDDDG, otherwise on Art. 6(1)(f) (funding the free game). Withdrawal applies for the future. Transfers to the USA are based on the EU-US Data Privacy Framework or Standard Contractual Clauses.

Note: these rules apply from version 2.0.1. In version 2.0, all age groups saw ads; under 16 and without an age they were requested as child-directed, always non-personalized.

9. Children and teens

Age information: after the fifth solved level, the app asks once for your age. On newer iOS versions it first asks for Apple's age range (“Declared Age Range”), which you or your family can share. Otherwise it asks for your month and year of birth; “Rather not say” is an option. Stored only on your device and not in the iCloud backup: your month and year of birth, or the age group reported by Apple with the date it was asked, or that you chose “Rather not say”. From month and year the game recalculates your age every time – as you get older, you move up to the next group by yourself. An age group reported by Apple is asked for again after a year.

Under “Age group” in the settings you can change your answer, but only toward more protection; an answer that would mean less protection is not accepted. If you made a mistake, delete and reinstall the app. Your age information only decides whether and how ads are requested (see above) and whether you get the daily free tip. The purpose is protecting minors (Art. 6(1)(c) GDPR where required, otherwise (f)); no interest profiles are created from it.

Under 13: no ads and no videos; instead there is a free tip every day as long as you have fewer than three tips, and no purchase button in the tip dialog. “Wobble Garden” is not specifically directed at children under 13. Minors need parental consent for purchases. We recommend protecting purchases in the device settings (Screen Time).

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

  • Google Ireland Limited – advertising via AdMob (separate or joint controllership under Google's terms)
  • Apple and Google – app stores, payment processing, accounts and device backup (separate controllers)
  • 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).

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.
