Preview first
Share the generated preview rather than the original image or message.
Tease & Share
Use a limited preview link instead of posting the full content. Let the recipient discover the preview before following the supported reveal workflow.
No phone number or email required for core Hat use.

The useful difference
Share the generated preview rather than the original image or message.
Review the access conditions and the route recipients use to request or open the content.
Tell the recipient what the link contains and what happens after opening it.
How it works
Choose supported content and generate the preview link.
Use an appropriate channel and verify the preview exposes only what you intend.
Complete the reveal workflow according to the controls available in the app.
Know the boundary
A preview link is shareable and the visible preview may be captured. Once content is revealed, recipient copies and device risks remain. Preview pages and encrypted Hat delivery have separate data boundaries.
