Tier 1 Protocol Local is the downloadable edition of Tier 1 Protocol — the world’s first encrypted semantic filesystem. It works like a hologram. Every record is encoded as waves and superposed into a single interference field; a query, encoded the same way, acts as the reference beam, and the matches reconstruct by interference — computed entirely inside the sealed field. The archive is never decrypted to be searched. The only decryption in the product happens when you, holding your case password, read a result.

You don’t have to take that on faith. With no key at all, the sealed archive still produces its full ranking, bit-for-bit — and yields no record text. Search runs on the seal, not past it.

The membership is the license. While your subscription is current, the package on this page is yours to download — join, download, install, and claim your license key with the email you used at checkout. Run it on your own machines — two activations. Updates are included while your subscription is current, and the newest package is always the one on this page. Your documents never leave your machine; the only outbound call the software makes is license verification.

$29/month or $249/year. Linux, x86_64 and ARM64 (glibc). Your documents, your library, your indexes — yours, on your machine.
