NO SUS: privacy toolkit site built as a Next.js static export with Tailwind v4

[https-shubhamsahu]

Hi all. I'm Shubham, a student developer, and I built NO SUS (https://nosus.foo) on my own. Sharing the site here because it's built with Tailwind CSS v4 and I'd love feedback on the UI.

What NO SUS is: a privacy toolkit (in Alpha) for people who share documents or use borrowed computers:

• Burn Notes / Burn Files: encrypted in the browser, no account on either side, open once and then burn. By default each single note or file also gets a two-digit pairing code, and while that code is valid (20 minutes by default) its key is stored on the server too. The key is swept within about 10 minutes after the code is used or expires.
• SecureSend: document sharing with view limits, expiry, revocation, and the viewer's entered email overlaid as a watermark. That watermark is an attribution clue, not verified identity.
• Go: open your Google Drive files on a borrowed PC without signing Google in there. You approve from the phone app with your phone's screen lock.

It's closed source. The app itself is Flutter (web app at https://app.nosus.foo, Android APK from https://github.com/https-shubhamsahu/nosus-app/releases/latest). The marketing site at nosus.foo, including the in-page burn tool, is a Next.js static export styled with Tailwind v4.

Things I'd like feedback on:

1. Is the "honest limits" table readable on small screens?
2. Do the comparison tables keep enough contrast and stay scannable on mobile?

Happy to answer questions about the build.
