Privacy Policy – Diamond Drop

for the app "Diamond Drop: Puzzle"

This is a non-binding English translation for your convenience. The German version of this privacy policy is legally binding.

Last updated: November 2026

In short: for the world ranking, level, diamonds, games played and country are sent to our server, without names and without tracking. Everything else stays on your device.

1. Controller

The controller within the meaning of the General Data Protection Regulation (GDPR) is:

2. World Ranking

Since version 1.1 there is a world ranking. So that you can see your place in it, the app sends the following information to our own server diamonds.kainzner.net after each game:

• a random installation ID that the app creates itself on first launch (not a device or advertising ID from Apple or Google)
• your current level, your diamonds and the number of games played
• the country from your device's region settings (not your location)

No name, no email address, no account and no location are transmitted. The server does not store IP addresses with this information. The ranking shows other players only with country, level and diamonds. The information is used only for the ranking and for aggregated statistics (for example how many players from how many countries are playing) and is not passed on to third parties. The connection is encrypted.

The legal basis is Art. 6 (1) lit. f GDPR (legitimate interest in operating the ranking). The information is kept for as long as the ranking exists. If you delete the app, a reinstall creates a new ID; the old entry can then no longer be linked to anyone. You need no internet connection and no account to play.

3. Local Storage

The app stores only what it needs for playing, and only on your device: your current level, the diamonds you earned, the random installation ID, the seed for your levels and your settings (language, sound). We have no access to this. If you delete the app, this data is deleted with it. Whether it is part of your own device backups depends on the settings on your device.

4. No Tracking, No Ads, No Cookies

The app uses no tracking, analytics tools, advertising, advertising IDs, cookies or comparable services whatsoever. No user profiles are created.

5. Purchases via the App Store and Google Play

The purchases Up to Level 50 and Endless Levels are handled exclusively through the Apple App Store (iPhone) or Google Play (Android). Payment data is processed only by the respective store; we receive no payment data and no information about you as a person. The app only asks the store whether a purchase exists and at what price the purchases are offered, which requires an internet connection. On Android, the app remembers on your device what has already been purchased so that it also works offline. The privacy policy of Apple or Google applies to this processing. The stores provide developers with aggregated sales figures; we receive crash reports from Apple only if you have allowed this in your device settings, and from Google according to the settings of your Android device.

6. Contact via Email

Apart from the information for the ranking, the app sends nothing to us. Only if you choose to email us do we process your email address and the information you provide in order to answer your inquiry. The legal basis is Art. 6 (1) lit. f GDPR (legitimate interest in responding to inquiries).

7. Encryption

The app uses no encryption of its own and no export-restricted or sanctioned encryption. Encrypted connections to Apple or Google for purchases and to our ranking server are established solely by the operating system of the device.

8. Your Rights as a Data Subject

Through the app we receive only the ranking information listed above, without a name. Where we process your data, you have the following rights under the GDPR, provided the legal requirements are met:

• Right of access (Art. 15 GDPR)
• Right to rectification (Art. 16 GDPR)
• Right to erasure (Art. 17 GDPR)
• Right to restriction of processing (Art. 18 GDPR)
• Right to data portability (Art. 20 GDPR)
• Right to object to processing (Art. 21 GDPR)

To exercise these rights, an informal message by email to christoph@kainzner.net is sufficient.

9. Right to Lodge a Complaint with the Supervisory Authority

You have the right to lodge a complaint with a data protection supervisory authority. The competent authority in Austria is:

10. Changes to This Privacy Policy

We reserve the right to amend this privacy policy to reflect changed legal requirements or changes to the app. The current version available on this page always applies.
