msgpunk

Msgpunk https://msgpunk.com is an end-to-end encrypted form service. It enables private data collection without either the form creator or the form respondent trusting a third-party hosting provider or even msgpunk itself.

Static websites need a way to accept form submissions, but every existing solution forces you to trust a third party with your leads. Free contact-form providers can monetize by harvesting respondent data and selling it to data brokers. For businesses, this means losing control of their leads. For respondents, it means their contact details end up with unknown third parties. Even email, the fallback, offers no guarantees: once sent, you have no visibility into how your address is stored, shared, or resold.

Msgpunk solves this by end-to-end encrypting form submissions for static sites. Form data is encrypted in the browser before it ever reaches a server. Only the form owner, holding the private key on their device can decrypt responses. No middleman, no data harvesting, no email required. Submissions arrive directly.

Not only are messages encrypted but form structure is also encrypted meaning that forms can be private unless respondents are given the key to be able to submit. The service knows nothing about what the form is about the data structure or of course the submissions.

The structure of the form is dynamic JSON which whilst in the demo was just a canned structure it actually is not too hard to put together a dynamic form builder for the forms. You can checkout the different available elements by heading to https://msgpunk.com and clicking the "Checkout an example form" button

This will be available for the https://punksystems.org website pretty soon.
