We use Google Fonts from Google Inc (1600 Amphitheatre Parkway Mountain View, CA 94043, USA) on our website.
You do not need to log in or enter a password to use Google fonts. Furthermore, no cookies are stored in your browser. The files (CSS, fonts) are requested via the Google domains fonts.googleapis.com and fonts.gstatic.com. According to Google, requests for CSS and fonts are completely separate from all other Google services. If you have a Google account, you do not need to worry that your Google account data will be transmitted to Google while using Google Fonts. Google records the use of CSS (Cascading Style Sheets) and the fonts used and stores this data securely. We will take a closer look at exactly how the data is stored.
What are Google Fonts?
Google Fonts (formerly Google Web Fonts) is an interactive directory of more than 800 fonts that can be used by the Google LLC for free use.
Many of these fonts are published under the SIL Open Font Licence, while others have been published under the Apache licence. Both are free software licences. This means we can use them freely without paying licence fees.
Why do we use Google Fonts on our website?
With Google Fonts, we can use fonts on our own website without having to upload them to our own server. Google Fonts is an important component in keeping the quality of our website at a high level. All Google fonts are automatically optimised for the web and this saves data volume and is a great advantage, especially for use on mobile devices. When you visit our site, the low file size ensures a fast loading time. Furthermore, Google Fonts are so-called secure web fonts. Different image synthesis systems (rendering) in different browsers, operating systems and mobile devices can lead to errors. Such errors can sometimes visually distort texts or entire websites. Thanks to the fast Content Delivery Network (CDN), there are no cross-platform problems with Google Fonts. Google Fonts supports all common browsers (Google Chrome, Mozilla Firefox, Apple Safari, Opera) and works reliably on most modern mobile operating systems, including Android 2.2+ and iOS 4.2+ (iPhone, iPad, iPod).
We therefore use Google Fonts so that we can present our entire online service as beautifully and uniformly as possible. According to Art. 6 para. 1 f lit. F GDPR, this already constitutes a "legitimate interest" in the processing of personal data. In this case, "legitimate interest" means both legal and economic or non-material interests that are recognised by the legal system.
What data is stored by Google?
When you visit our website, the fonts are reloaded via a Google server. This external call transmits data to the Google server. In this way, Google also recognises that you or your IP address is visiting our website. The Google Fonts API was developed to reduce the collection, storage and use of end user data to what is necessary for the efficient provision of fonts. Incidentally, API stands for "Application Programming Interface" and is used, among other things, as a data transmitter in the software sector.
Google Fonts stores CSS and font requests securely at Google and is therefore protected. Google can determine the popularity of the fonts through the collected usage figures. Google publishes the results on internal analysis pages, such as Google Analytics. Google also uses data from its own web crawler to determine which websites use Google fonts. This data is published in the BigQuery database of Google Fonts. BigQuery is a web service from Google for companies that want to move and analyse large amounts of data.
However, it should be noted that every Google Font request also automatically transmits information such as IP address, language settings, browser screen resolution, browser version and browser name to the Google servers. It is not clear whether this data is also stored or whether it is clearly communicated by Google.
How long and where is the data stored?
Google stores requests for CSS assets for one day on your servers, which are mainly located outside the EU. This allows us to use the fonts with the help of a Google stylesheet. A stylesheet is a format template that can be used to quickly and easily change the design or font of a website, for example.
The font files are stored by Google for one year. Google's aim is to fundamentally improve the loading time of websites. If millions of websites refer to the same fonts, they are cached after the first visit and immediately reappear on all other websites visited later. Google sometimes updates font files to reduce the file size, increase language coverage and improve the design.
How can I delete my data or prevent data storage?
The data that Google stores for one day or one year cannot simply be deleted. The data is automatically transmitted to Google when the page is accessed. To delete this data prematurely, you must contact Google support at https://support.google.com/?hl=de&tid=211098124 contact us. In this case, you can only prevent data storage if you do not visit our website.
Unlike other web fonts, Google allows us unrestricted access to all fonts. This means we have unlimited access to a sea of fonts and can therefore get the best out of our website. You can find out more about Google Fonts and other questions at https://developers.google.com/fonts/faq?tid=211098124. Although Google addresses data protection issues there, it does not provide any really detailed information about data storage. It is relatively difficult (almost impossible) to obtain really precise information from Google about stored data.
