Dear CryptoCloud
Thank you for your message and your interest in our communication solutions.
In our Threema Shop, licenses can be purchased for Android devices. After the completed
purchase process, the installation on the mobile device is done using an APK file. Please
find further information at https://shop.threema.ch/.
For commercial customers, we recommend using Threema Work, which is specifically built for
companies: https://threema.ch/en/work
I hope, that I could help with this information. For further questions, please do not
hesitate to contact us again.
