Privacy by architecture,
not by policy.
Sharp#Soft protects your files, messages, and identity on the desktop. The keys to your data are created on your device and never leave it — so no one can read what's yours. Not an intruder, not our servers — not even us.
This site uses no cookies, no analytics, and no trackers. That's the point.
Only you hold the keys
The keys to your data are created on your device and never leave it — not even to us. Nothing opens without the credential you keep. There's no master key and no back door, because none can exist.
Your files and messages stay yours
Documents, files, and messages are sealed so only the people you choose can open them — whether they live on your device or in the cloud. No admin override, no support team that can peek, no "trust us."
Even who you talk to stays private
Outsiders can't read your messages — or even see who you're talking to, how often, or how much. All anyone watching the network sees is sealed envelopes.
Two ways to mean "private"
Most products that market privacy still hold the keys to your data. The difference matters more than any feature list.
How most services work — policy-private
"We could read your data, but we choose not to."
- The operator keeps the technical ability to read your content
- Privacy depends on staff conduct, internal controls, and policy
- An insider, a breach, or a change of ownership turns their capability into your exposure
How Sharp#Soft works — structurally private
"We could not read your data even if we wanted to."
- Our servers hold only sealed ciphertext — the keys live with you
- Privacy rests on cryptography and architecture, not on conduct
- No one can be pressured into opening what no one can open
"We can't read your messages — by design, not by promise." Every claim we make is backed by a published, verifiable chain from statement to architecture — the whitepaper shows you how to check for yourself.
What ships at launch
One desktop app, launching Windows-first in 2026. Everything below arrives with version 1.0.
Sharp Account
Your encrypted personal container and entry point to the system. Every key derives from it, and it opens only with the credential you hold.
Private Identities
Communicate without exposing personal information. One login, many faces — separate identities keep work and personal life apart.
Encrypted file vault
Store files encrypted with your own key — retrievable only by you. View and edit private documents without leaving traces on disk.
Sealed messaging
Encrypted messaging between identities in a familiar chat view — sealed end-to-end, with the routing metadata protected too.
Recovery — on your terms
An optional recovery path for credential loss that you configure and control. Skip it, and you keep the strongest possible guarantee.
Simple subscription
Buy storage and extra identities, see your usage, manage your plan. We sell subscriptions — we don't sell you.
On the roadmap, after launch: shared encrypted spaces — CryptLock-based containers you can invite others into, with the same no-master-account guarantee. Sharing access never means sharing your keys.
We publish our limits
A privacy claim you can't check is worth exactly nothing. So we do two things differently: every claim we make traces to the architecture that enforces it — and we name, in print, what we don't protect against.
- No master account, no support-team override, no key escrow
- Built and operated from Sweden, under EU privacy law
- The whitepaper lists the boundaries as carefully as the guarantees
Named boundaries — a sample
- We can't hide that you use Sharp#Soft — only what for, with whom, and about what
- We can't recall a message a recipient chooses to copy
- We can't protect a device that's already fully compromised
