Privacy that's
actually fast.
Most encrypted tools make you choose between privacy and a product that works. Solara refuses the trade-off — encrypted mail, storage, calendar and outreach, with on-device AI and Gmail-grade speed.
You shouldn't pick between private and usable.
The encrypted players are slow and thin. The fast players read your data. Solara is the first to be both.
Your keys are generated on your device and never leave it. We literally cannot read your mail, files, or calendar — not for ads, not for AI, not under subpoena.
Keyboard-driven, instant search inside encrypted content, a command palette, a terminal, and an AI agent that actually does the work — all without a server ever seeing plaintext.
Everything you'd switch for.
End-to-end encryption
Mail, files, events and invites encrypted with keys only you hold.
Hide-my-email aliases
A unique address for every signup. Revoke one and it simply stops.
Aria, your AI agent
Voice or text. Cleans your inbox, drafts replies, books meetings — on-device.
Encrypted search
Search inside your files and mail. The index never sees plaintext server-side.
Terminal & API
A popup CLI in every app, IMAP/SMTP, custom domains and an API. Built for devs.
Spam & trust checker
Score every email before you send — deliverability and authentication, fixed by Aria.
A whole suite, not an app.
Mail, KhromeVault, Calendar, Campaigns and KhromeLab share one key, one agent, one command bar. A reply becomes a booked meeting becomes a calendar invite — all encrypted, end to end, anchored on Khromosome.

Meet Aria →Your data belongs to you — not advertisers, not governments, not us.
Every other "free" suite is free because you're the product. Solara is built so that we cannot read your mail, open your files, or sell your behavior — and Khromosome lets you prove it instead of taking our word for it.
Trust nothing. Verify everything.
Proton asks you to trust Switzerland. We ask you to trust math and a public ledger — the same zero-knowledge model, made checkable.
End-to-end encryption
Keys are generated on your device and never leave it. Mail, files, events and notes are ciphertext before they touch a server.
On-chain verifiable
Every file's integrity is anchored to Khromosome (chain 777001). Your client checks the chain on read — tampering fails loudly, automatically.
Open source & audited
The crypto core is open and went through three rounds of independent adversarial audit. Inspect it, or run your own.
Self-hosted & sovereign
Runs on infrastructure we own, not a hyperscaler. Bring your own domain, your own node, your own keys.
One account, every device
A single encrypted identity unlocks Mail, KhromeVault, Calendar, Campaigns and KhromeLab on web, desktop and mobile.
Free forever
A genuinely useful free tier with real encryption — no trial timer, no card. Upgrade only when you need more.
