Flashpaper - Self-destructing secret sharing with no database
Show HN: Flashpaper – Self-destructing secret sharing with no database
Flashpaper is a privacy-first tool for sending private notes, keys, and files that vanish instantly upon viewing. Unlike traditional services, it stores secrets exclusively in volatile RAM, ensuring nothing is ever written to disk or a database. Featuring unique anti-capture technology like the Spotlight Lens and optional view timers, Flashpaper prevents screenshots and shoulder surfing. With support for 10MB client-encrypted attachments and a strict 24-hour max retention policy, it offers a secure, account-free alternative to legacy tools like Privnote and Bitwarden Send.

This is very cool. I can't comment on the encryption, but I did want to mention that your page design is pretty bad, which is a shame for something so useful.
It looks AI generated, you can probably paste this into your LLM of choice to improve it.
It has pretty subtle information hierarchy.
All the text sizes except for the main heading are withing 15% size of each other. More differentiation here would be the lowest hanging fruit, I think.
I'd also say all the text needs to increase in size in general.
It's pretty low contrast as well, made worse by the small font size. And some things, like button highlights, are too high-contrast. They pull too strongly away from the rest of the text and flow.
You also have a lot of buttons, some of them are even just to pre-fill demo text. I'd cut it way down.
I think the goal should be that the critical path to making a 'burn link' is at the very top of the information hierarchy. Big heading "Your Secret", with very well signposted text box.
Big heading "Link Expiration" with a big range slider (with number input.)
(Sliders have the advantage of structurally communicating what you're doing. You fill up the available slider to add more time, you shrink it to have less time.)
The overall idea is that the eye naturally snaps to the next step when the previous one is done with zero effort. Really blast the information and steps into people's brains.
I hope Flashpaper takes off!

How does this compare with other pastebins like privatebin? https://privatebin.info/
