Where this privacy policy Applies

This privacy policy applies to the STAmina Apnea Trainer App (“the App”). When designing the App, we have made sure that as little as possible information that directly identifies you is collected.

"Personal data" means any information relating to an identified or identifiable natural person (hereinafter "data subject"); an identifiable natural person is one who can be identified, directly or indirectly, in particular by reference to an identifier such as a name, an identification number, location data, an online identifier (e.g., cookie) or to one or more factors specific to the physical, physiological, genetic, mental, economic, cultural or social identity of that natural person.

However, we reserve the right to put this data to additional uses to the extent permitted or required by law or necessary to support legal or criminal investigations. In this case, we will inform you again about this further data processing to the extent required by law and obtain your consent.

The same applies to such processing operations that are necessary for the performance of pre-contractual measures, for example in the case of enquiries about the App.
  • legal obligation, insofar as we are subject to a legal obligation that requires the processing of personal data, such as for the fulfilment of tax obligations (Art. 6 (1) c) GDPR).

How do we use your data to improve the STAmina Apnea Trainer App?

We analyze the use of the App anonymously in order to better understand and optimize the behavior when using our services.

For that purpose, we use Visual Studio App Center (Microsoft). With the App Center we receive crash and diagnostic data as well as evaluations about the usage within the App. In addition to the actual error report, this includes the country code, language used, manufacturer, version of the operating system of the mobile device, the installed version of the app as well as the date and time of the event that occurred (error or crash of the App). This data is used exclusively to analyze any problems or crashes that may have occurred with the app. Detailed information can be found at:

The app uses the Firebase tool, which is part of the Firebase platform of Google Inc, 1600 Amphitheatre Parkway Mountain View, CA 94043, USA, to obtain statistics on how the App is used, in particular active user numbers, session length, stability rating and storage time. Answers logs the use of the app and we evaluate user behaviour and user activity in general, i.e. not on a personal basis.

For this purpose, the following data is transferred to the Analytics Engine: name and AppStore ID, build version, individual device installation key, timestamp, device model, device name, device operating system name and version numbers, the language and country settings of the device (iOS), the number of CPU cores on the device (iOS), whether a device has the status "jailbreak" (iOS) or "root " (Android), app lifecycle events (iOS) and app activities (Android); The legal basis for this data processing is our legitimate interest.

The app also uses the tool Crashlytics, which is part of the platform Firebase of Google Inc to log crashes of the app. No personal data is transmitted. Only real-time crash reports with precise details of code locations and device information are sent, which is intended to simplify maintenance and improve the resulting stability of the app.

How long do we store your data?

We keep your personal data only as long as we need it for legitimate business purposes and as permitted by Applicable law. To protect the safety and security of our users on and off our services, we implement a safety retention window of three months following account deletion. During this period, account information will be retained although the account will of course not be visible on the services anymore.

In practice, we delete or anonymize your data upon deletion of your account (following the safety retention window), unless:

  • we must keep it to comply with Applicable law (for instance, some “traffic data” is kept for one year to comply with statutory data retention obligations),
  • we must keep it to evidence our compliance with Applicable law (for instance, records of consents to our Terms, Privacy Policy and other similar consents),
  • there is an outstanding issue, claim or dispute requiring us to keep the relevant information until it is resolved, or
  • the information must be kept for our legitimate business interests, such as fraud prevention and enhancing users’ safety and security. For example, information may need to be kept preventing a user who was banned for unsafe behavior or security incidents from opening a new account.

Keep in mind that even though our systems are designed to carry out data deletion processes according to the above standards, we cannot promise that all data will be deleted within a specific time-frame due to technical constraints.

How do we protect your data?

Note on data transfer to the USA

Amongst other things, tools from companies based in the USA are integrated in the App. If these tools are active, your personal data may be transferred to the US servers of the respective companies. We would like to point out that the USA is not a safe third country in the sense of Latvia or EU data protection law. US companies are obliged to hand over personal data to security authorities without you as a data subject being able to take legal action against this.

We have no influence on these processing activities.
