My apps are free, without ads. I don't really make money from them. Thus, I cannot provide support in my free time. If you have any issues, please fill them on Github.
If you like to pay me for supporting you, contact me on cotech.de.
For consulting services contact me on cotech.de.
I support end-to-end encrypted emails.
Keys are automatically exchanged via Autocrypt and available via WKD.
Alternatively, you can manually download the key.
You can also download my OpenPGP Git Signing Key (not for communication).
