If we have received personal data from you via other communication channels (e.g., by email), the following Privacy Policy also applies.

Given that our App and the technologies on which it is based, as well as our business processes are subject to continuous development, the Privacy Policy may need to be changed too. All future changes will be published here.

3. Automatic data processing during App use

a. Log files when using our App

If you download our App via an app store, the required information is transferred to the app store, i.e. in particular username, email address and customer number of your account, time of download, payment information and the individual device identification number. We have no influence on this data collection and are not responsible for it. We only process the data insofar as it is necessary for downloading the App to your mobile device.

If you wish to use our App, we collect the following data that is technically necessary for us to offer you the functions of our App and to ensure stability and security:

That data is:
1. Date and time of your request
2. Duration of your visit
3. Time zone difference compared to Greenwich Mean Time (GMT)
4. Content of the request (specific page)
5. Access status/HTTP status code
6. IP address used (if applicable: in anonymised form)
7. Device Operating Systems (Android or iOS)

aa. Purpose and legal basis of data processing

We process data related to the end device, in order to create use statistics, for example, or to identify and trace unauthorised attempts to access our web servers. We only create profiles regarding the use of our App in anonymised form and only to improve user navigation and optimise our services. Our legitimate interest in data processing pursuant to Art. 6 para. 1 sentence 1 lit. f GDPR also lies in these purposes. We do not create or process behaviour profiles relating to a specific person from the aforementioned information.

bb. Duration of data storage

The data will be deleted as soon as they are no longer necessary to achieve the purpose for which they were collected. In the case of the collection of data for the provision of the App, this is the case when the respective session has ended.

b. Firebase by Google

We use the Firebase service from Google LLC (1600 Amphitheatre Parkway, Mountain View, CA 94043, USA) in order to derive application behavioural analytics. We use that information to see how users interact with our App. Firebase is part of the Google Cloud Platform and offers numerous services for developers. A list can be found here:

Currently, we use the following Firebase service:

Google Analytics for Firebase

The App uses a cookie-like token (Instance ID) to recognize the device at Firebase Analytics and to enable an analysis of your usage behaviour only with your prior consent to do so. The token is unique to the App and not retained on reinstalling the App or resetting the mobile device. We have disabled collection of Advertising IDs and Identifiers, so that persistent, a cross-app and cross-device recognition is not possible. The information about app usage gathered by means of the Instance ID is sent to Google’s servers in the USA. The IP address used during use is shortened before leaving the EU or the EEA. Only in exceptional cases does this reduction take place in the USA. The IP address transmitted by the App is not linked to any other data at Google. Google will use this data to analyze app usage on behalf of AQ Green
TeC GmbH, and compile reports for AQ Green TeC GmbH. These reports are anonymised.

Therefore, they do not contain personal data and do not allow the identification of individual users. Instead, the data is aggregated over all users. These reports include, for example, the frequency of use, the place of use and the content viewed. With the help of these reports, we can improve our product quality. The legal basis for the use of Firebase Analytics is Art. 6 para. 1 sentence 1 lit a. GDPR. The collected data will be deleted after 2 months. The analysis of you your user data is only carried out if you have given your consent in advance to do so. You can also opt-out of the analysis of your user data at any time by deactivating the “Analytics” settings in the app. This prevents the future collection of your data and sending it to Google. You will need to disable this setting on all devices on which you use the App.

Firebase Crashlytics

Only with your prior consent, we are using “Firebase Crashlytics” for crash reporting’s, which sends the aforementioned Instance ID when using the App. When a crash occurs, the App will also send crash reports to Google’s servers to help us improve the quality of the app by being able to in-depth analyze crashes of the app.
The legal basis for the use of Firebase Crashlytics is Art. 6 para.1 sentence 1 lit. a GDPR. The collected data will be deleted after 90 days. Further information and Google’s and Firebase’s current privacy policy can be found at;

The analysis of you your crash report is only carried out if you have given your consent in advance to do so. You can also opt-out of the analysis of your crash report data at any time by deactivating the “Performance Tracking” settings in the app. This prevents the future submission of your crash report and sending it to Google. You will need to disable this setting on all devices on which you use the App.

c. Sentry

We use Sentry to improve the technical stability of our service by monitoring system stability and identifying code errors. By using Sentry, information about your use of this service may be transmitted to a server of Sentry (Functional Software Inc., Sentry, 132 Hawthorne Street, San Francisco, California 94107, USA.).
