Like typeform just e2e encrypted with a symmetric key as part of the link.
You can share the link like usual and know that nobody can read the submission.
The idea is pretty simple and I have already started building. Would love to hear your use case. Maybe you need extra features I could incorporate or there is an industry I haven’t thought of.
If there is enough interest I can spin up a hosted version. But the code is open source. Happy to share :)
