Privacy Agreement blindmate

(zu deutscher Version wechseln )

Your data is your data

We only store and process data that is necessary for running the app or that we as developers consider absolutely necessary to improve the app. We have designed blindmate to provide you best possible privacy. We do not advertise on blindmate, we do not sell data. And to be as transparent as possible, we go beyond the legal requirements and list absolutely all the data we collect and explain how we use it. We hope that it is possible to run an app sustainably without selling users' data and to finance ourselves (in the long rund) through an affordable premium model without ever having to sell your data. Should this no longer be possible one day, we would inform you.

Please excuse language mistakes. We translated this document to give you as much transparency as we can, however, English is not our first language and legal documents are challenging to translate. Please let us know if you spot a mistake or something is unclear.

2. What information is collected by us when you use blindmate?

Summary: The processing of stored data is necessary for the operation of our app and in order to improve the app. In particular, we collect information to identify and fix bugs (without drawing conclusions about your person). We analyse the basic features of user behaviour (frequency and regularity of various actions).

2.1 Using your photos or camera (with consent, optional) If you want to upload an image when you create your account or set up your search profile, we will ask you for permission to use your photos or camera. If you do not give this permission, we will not use this data. It will then not be possible to activate your search. You can later grant or revoke this consent in the settings of your operating system. If you allow access to this data, the app will only access your data and transfer it to our servers as far as it is necessary to provide the functionality. We will delete this data it when it is no longer required to provide the service or when you revoke the right to use it and there is no legal obligation to retain it. The legal basis for the processing is Art. 6 para. 1 sentence 1 lit. f GMPR.

2.2 Collection of site data (with consent, optional) Our offer includes so-called Location Based Services, with which your search can be tailored to your particular location (this feature is optional) You can only use this function after you have agreed that we can collect your location data using GPS and your IP address for the purpose of providing services. You can allow or revoke this function in the settings of the App or your mobile operating system at any time.

2.3 Sending push notifications (with consent, optional) You can register to receive our push notifications. You will receive regular information about our services via our push notifications. In order to register, you must confirm the receipt of notifications or allow them in the settings of your operating system. This process is documented and saved. This includes saving the time of registration and your device identification. The collection of this data is necessary for us to be able to display the push notifications on the one hand and to be able to trace the processes in case of misuse on the other hand and therefore serves as a legal safeguard. This data is processed on the basis of Art. 6 Para. 1 lit. a GDPR. You can revoke your consent to the storage and use of your personal data to receive our push notifications and the statistical survey described above at any time with effect for the future. To revoke your consent, you can unsubscribe from the designated setting for receiving push notifications in your app settings in your operating system. Your data will be deleted as soon as they are no longer required for the purpose of their collection. Your data will therefore be stored for as long as the subscription to our push notifications is active. Below, you can find a complete list of all data processed by us, as well as the purpose of use.

When personal data is processed on the basis of express consent pursuant to Art. 6 para. 1 letter a GDPR, this data is stored until the person concerned revokes his or her consent. If there are legal retention periods for data which are processed within the framework of legal or similar obligations based on Art. 6 Para. 1 letter b GDPR, these data are routinely deleted after the retention periods have expired, provided that they are no longer required for the fulfilment or initiation of a contract and/or we have no justified interest in their further storage.
