VastDisk, zero-knowledge encrypted file sharing (need testers)

everything is encrypted client-side before upload, so even the developer, can’t access user data.

current features:
- upload & share files via link
- client-side encryption (zero-knowledge)
- no account required (modest guest limits)
- fast/simple UI

im looking for:

- getting initial users
- break things
- give minimal feedback

-> https://vastdisk.com/

what I specifically need feedback on:
- upload speed / reliability (being worked on)
- UX (is anything confusing?)
- trust concerns (would you actually use this? why? etc)

ill respond to every comment. anything is useful. thank you!
