A dedicated intake
Publish the intended organization’s intake route and make its purpose clear.
Sealed Tip
A separate route for sensitive submissions.
Give people an intake link for encrypted tips or supporting material. Keep the submission route separate from an ordinary email inbox or public feedback wall.
No phone number or email required for core Hat use.
The useful difference
A clearer way to handle sensitive work.
Encrypted submission
The documented tip flow encrypts content before delivery to the recipient.
Responsible handling
Define who reviews submissions, how recipients verify the route and what retention rules apply.
How it works
Three deliberate steps.
Create an intake route
Set up the supported Intake Hat and review its public link.
Publish clear instructions
Explain acceptable material, response expectations and the risks outside the encryption boundary.
Review securely
Authorized recipients use the supported retrieval flow and follow their own handling procedures.
Know the boundary
Choose controls with clear expectations.
Encryption does not guarantee anonymity or protection from retaliation. Content, attachments, devices, traffic and details volunteered by the submitter may identify a source. For high-risk situations, review the threat model before submitting.
