The setup was a breeze; had branding and CNAME with validation in under 30 minutes.
If you have ever used the Secrets App in NextCloud you will have a similar experience using InPrivy with a more attractive UI.

I especially like the different expiration and access modes. And in my opinion the best feature is the Public Sharing URL, it enables clients to send things to me securely. Of course the GDPR compliance is a plus as well.

Data is encrypted (TLS) in-transit and stored at-rest using AES 256.

Overall I am very pleased with this application and will be using it daily for my secure messaging and file transfers / sharing.
