Atto

Windows closed beta

Unsigned early-tester build (zip — Cloudflare Pages blocks raw .exe). Not a marketed SKU — Azure signing still pending. Mac remains the primary kit.

Already installed? In Atto → Home → AdvancedCheck for updates (or download the latest zip below and install over the old one — your vault stays on this PC).

Download Windows installer (zip) Unzip → Atto_0.1.4_x64-setup.exe · ~20 MB · unsigned · build 7

Install

  1. Buy / claim on Stripe → download license.json from the claim page. Friend comps: ask Support for an invite.
  2. Download the zip above.
  3. Confirm the zip SHA-256 against SHA256SUMS.txt (hash starts 7d561045…) before you run anything.
  4. Unzip, run Atto_0.1.4_x64-setup.exe. SmartScreen: More info → Run anyway (expected for this unsigned early-tester build). Quit Atto first if upgrading — install over the old app; your vault stays put.
  5. In Atto → Import license (or save as %USERPROFILE%\.atto\license.json).

Without a license, Atto's app features stay locked. Your vault folder is always ordinary files on your disk — never encrypted, never held hostage.
