Secure Files.
Sealed before they leave your device.
A file vault that works like the file manager you already know — with one structural difference: every file is encrypted on your device, with your key, before it is stored. What reaches our servers is a sealed envelope we cannot open.
Why it matters
Cloud storage convenience, without the "trust us" part.
Sealed before it leaves
Encryption happens on your device, with a key created on your device. By the time a file travels anywhere, it is already unreadable to everyone but you.
Retrievable only by you
There is no admin override, no support team that can peek, no master key. Our servers store sealed envelopes — we couldn't open your files if we wanted to.
View without traces
Open and edit private documents inside the app without leaving readable copies scattered on disk. What's sealed stays sealed.
How it protects you
The same first step of the security model, applied to storage.
Sealing happens client-side. Your files are encrypted on your device before upload — the server's only job is to hold and return sealed envelopes. That's step one of the security walkthrough, and it's why a breach of our servers, an insider, or a legal demand cannot expose your file contents: there is nothing readable to expose.
And the honest limit: we can't protect a device that is already fully compromised — if malware can read your screen, it can read what you can read. We publish that boundary, and the others, in the whitepaper.
Your files. Actually yours.
Secure Files ships with Sharp#Soft 1.0 in 2026, Windows first.
