In the following, we would like to inform you about the purposes, type and scope of the processing of your personal data while using the Contrasts App (hereinafter also referred to as the "App"). The legal basis for the level of data protection within the App is the Regulation (EU) 2016/679 (GDPR).
Responsible for the processing of personal data within the app is:

The app allows you to create color pairs and determine their contrast to each other and thus the legibility.
When using the app, the data processing that takes place can be divided into three main categories:
The Contrasts app is available through the App Store operated by Apple Inc. The download may require prior registration with the App Store and installation of the App Store software. We have no control over the collection and processing of your personal information in connection with registering and providing downloads from the App Store. Apple Inc. as the operator of the App Store is solely responsible in this respect.
For more information on this data processing, please refer to the App Store Privacy Policy:
The following data is collected when the app is called up:
This data is temporarily stored in a log file for the following purposes:
The legal basis for the above-mentioned data processing is based on Art. 6 para. 1 letter f) GDPR.
In order for our app to function properly, it is necessary for you to allow and grant access to certain functions of your terminal device, so that certain data is stored on your terminal device. You will be prompted to grant the appropriate access authorization once at the beginning or when you use the respective function.
If you create color pairs, they will be stored directly in the memory of your mobile device, depending on the installation location of the app.
The app allows you to synchronize created color pairs across all your devices using iCloud. You can disable syncing in the iCloud system settings.
Color pairs stored on your stored device will not be transferred to us.
An Internet connection is only required when sending crash reports and usage statistics.
You can send color pairs you have created to other people. A system dialog will appear where you can share your content (e.g. via contacts, e-mail, social media). A data processing by us as well as a transmission of the contact data to us does not take place.
If you want to give us feedback, you can do so via the e-mail form within the app. We ask you not to send any further personal data of you or other persons within the feedback function to us. The legal basis for data processing within the framework of the feedback function is Art. 6 para. 1 lit. a) GDPR. Your feedback messages will be deleted after 4 weeks.
System-side usage statistics and error reports can be collected via Apple Inc. This system setting is not specific to the Contrasts App and can be deactivated in the device settings.
If you access websites via the in-app browser (e.g. via links), your personal data will be processed on these websites in deviation from this privacy policy. This privacy policy only applies to our App. We ask you to read the privacy policies of the linked websites. We are not responsible for the websites linked within the App and do not endorse their content. For illegal, incorrect or incomplete content as well as for damages resulting from the use or non-use of the information, the provider of the website to which the link was made is solely liable.
According to Art. 15 para. 1 GDPR you have the right to request information about the personal data we have stored about you.
In addition, if the legal requirements are met, you have the right to correct (Art. 16 GDPR), delete (Art. 17 GDPR) and restrict the processing (Art. 18 GDPR) of your personal data.
If data processing is based on Art. 6 para. 1 lit. e) or f) GDPR, you have the right to object under Art. 21 GDPR. If you object to data processing, it will not be carried out in future unless the data controller can prove that there are compelling reasons for further processing worthy of protection which outweigh the data subject's interest in objecting.
If you yourself have provided the processed data, you have a right to data
transfer in accordance with Art. 20 GDPR.
If the data processing is based on consent pursuant to Art. 6 para. 1
letter a) GDPR, you may revoke such consent at any time with effect for
the future, without affecting the legality of the previous processing.
In the above-mentioned cases, in case of open questions or complaints, please contact the above-mentioned contact address in writing or by e-mail.
You also have the right to complain to a data protection supervisory authority. The data protection supervisory authority of the federal state in which you live or in which the person responsible is based is responsible.
This privacy policy is current and dated May 22, 2021, and may be subject to change as our app develops or new technologies are implemented.
