App privacy policy

We take data protection and confidentiality extremely seriously and comply with national and European data protection regulations. We therefore want to explain the most important aspects with regard to the collection, processing and use of data, particularly which information and personal data is stored and how we handle it. 

Further or deviating data protection provisions may exist in relation to individual offers or services provided via our app. You shall be provided with these special provisions within the scope of the offer or service and they shall take precedence over the general provisions.

1. Data controller

The entity responsible for the collection, processing and use of your personal data as defined by Germany’s Federal Data Protection Act is Tetra GmbH, Herrenteich 78, 49324 Melle, Germany. 

2. Collection of personal data 

To use this app, you must open an account. The following personal information is required to this end: 

E-mail address 

After registering, you will receive an e-mail with a link for confirming your registration. The double-opt-in procedure serves to prevent spam and provide legal certainty to senders of e-mails with commercial content as the sending of unsolicited commercial e-mails is prohibited. 

2.1. Filter alert 

The following personal information is required for you to use the cartridge reminder. 

E-mail adress 

Within the scope of this feature, the e-mail address is used to send you e-mail reminders, for example in relation to water changes. 

2.2. Retailer search/location data (Google Maps)

To find retailers near you, we need to access your device’s current location. Within the scope of the retailer search service, we use GPS to detect your current location so that we can quickly provide you with information about your immediate surrounding area. To visually display maps, we use the Google Maps API from Google Inc. (Google). When Google Maps is used, Google also collects, processes and uses data about the use of the Maps functions by app users. The Google Maps Terms of Service can be found at https://www.google.com/intl/en_en/help/terms_maps.html. Further information about the Google privacy policy can be found at:

This app uses Google Analytics, a web analytics service provided by Google Inc. (‘Google’). Google Analytics uses ‘cookies’, which are text files saved on your smartphone that make it possible to analyse how you use the app. The information generated by the cookie about your use of the app will generally be sent to a Google server in the United States, where it will be saved. On behalf of the app provider, Google will use this information to evaluate your use of the app and compile activity reports. The data transferred from your smartphone as part of the Google Analytics service will not be combined with other data held by Google. You may refuse the use of cookies by selecting the appropriate settings on your browser. However, please note that if you do so, you may not be able to make full use of all the functions of this app. Furthermore, you can prevent Google from acquiring and processing the information generated by the cookie concerning your use of this app by downloading and installing the browser plug-in available at: https://tools.google.com/dlpage/gaoptout?hl=en.
