Safety starts with understanding how developers collect and share your data. Data privacy and security practices may vary based on your use, region, and age. The developer provided this information and may update it over time.
For very simple stuff no problem. But sending documents is very difficult. They don't really like PDFs, only JPEGs. English is the only second language option and even then, the English settings are very rudimentary. I still end up having to call and send documents by post. not even email seems to be an option. On the phone they will suggest sending a FAX like it's 1972 or something.

Dear TK I was pretty happy with the app, very informative and useful, with good English language support, but after the last update it doesn't allow me to open it anymore, because of my Android version, it's really sad, because to use it I would need to buy another phone, but everything else works really well on my phone and I don't want to change it, as the TK app is the only app that is not backwards compatible. I hope in the future updates you could implement backwards compatibility.

Wir können Ihren Unmut verstehen, jedoch erfordert unser hohes Sicherheitskonzept zum Schutz Ihrer Sozialdaten mindestens Android 10. Alternativ können Sie sich in "Meine TK" auf tk.de einloggen und dort viele Ihrer Anliegen erledigen. Freundliche Grüße, Ihre TK-App

I have to say, this app has improved a lot over the last few years, to the point where it's really convenient to use. Thanks TK! Also, btw, for having (still limited) English support. What I still don't like at all is the fact that the Selfy-ID process forcess you to download and install a 3rd party App!? If you want to use a 3rd party service for ID that's fine, but just use a browser-base link instead. Adding unnecessary apps to people's phones for a single use case ist not OK.
