Yes, we can see the data you have created. Just like any other software-as-a-service provider can or must be able to see the data, if the data has to be forwarded to authorities due to criminal relevance.
How we access your data is precisely defined on our GDPR / CCPA page. The advantage that we can offer you compared to other competitors is that all data is stored in our data center in Vienna and is not shared with third-party providers.
