Privacy

This policy describes how we process personal data in the Gemmi Wave app. We follow the Swiss Federal Act on Data Protection (FADP); where the EU General Data Protection Regulation (GDPR) applies, it applies in addition. Version: 6 November 2026. The German version is authoritative.

Controller

Trizoun - Tourismus & Digital, simple partnership of Roman Zoun and Ivayla Trifonova, Hauptstrasse 32d, 5506 Mägenwil, Switzerland. UID CHE-280.882.880.

Questions about privacy and your data: info@trizoun.ch.

In short

• You play without an account, email address or phone number.
• We use no advertising ID, no tracking and no third-party analytics or advertising services.
• Data is stored on servers in Switzerland.

On your device

The app stores your running games, your best score and settings such as sound on or off on your device. For online features it keeps a random access key in the device's protected storage (Keychain or Keystore).

Leaderboard and Spring of the Day

When you use an online feature for the first time, we create an anonymous profile. For this we process:

• a random profile ID and the access key, the latter only as an unreadable hash
• the time of creation and of your last activity
• your player name, if you choose one. Please do not use your real name
• your ranked results with score and time
• the game log (your moves). We need it to verify a result before it enters the leaderboard. We delete it after at most 7 days; the score remains
• reports of player names: who reported, who was reported and which name

All players can see your player name (or “Anonymous”) and your score on the leaderboard.

Partner banners

After a game we show banners from local partners. Everyone sees the same banners; they are not tailored to you. We only count how often a banner was shown and tapped per day, without any link to you or your device. Tapping opens the partner's website, where the partner's privacy policy applies.

Server logs

Requests to our servers create technical logs with IP address, time, requested address and response code. We need them for operation and security, for example to limit abuse. The logs are overwritten continuously, usually within a few days.

Who receives data

• Infomaniak Network SA, Geneva, Switzerland: hosting of server and database

We do not sell personal data and do not pass it on for advertising. Apple and Google handle the app download under their own privacy terms.

How long we keep data

• Game logs: at most 7 days
• Unranked runs: 30 days
• Profile, player name and results: until you delete the profile, at the latest 24 months after your last activity
• Banner counts contain no personal data

You can delete your data at any time in the app under “Settings” with “Delete my data” (or under “Spring of the Day” with “Delete profile”). Name, tries and results are then deleted immediately.

If you have already removed the app, write to info@trizoun.ch with your profile ID or your player name and the approximate date so we can find the profile. Otherwise we delete it automatically 24 months after your last activity.

Children

Gemmi Wave is intended for players aged 8 and over. We do not ask for age, real name or contact details.

Your rights

You can request access to your data, have it corrected or deleted, receive it in a common format and object to processing. Write to info@trizoun.ch. Since we do not know who you are, we need the profile ID shown in the app.

You can also contact the Swiss Federal Data Protection and Information Commissioner (FDPIC). For people in the EU, the supervisory authority of their country is responsible.

Changes

When we add new features or services, we update this policy. The version on this page applies.
