Products and scope
KK-SOFT brings together three Windows product families: KK-SECURE for endpoint protection, KK-PDF Pro for documents and OCR, and KK-RAR for archives. The catalog helps you choose an edition, check requirements and verify its SHA-256 before installing.
The technical notes describe the actual components, data flows, Windows privilege boundaries and open verification questions. A cited standard explains the design context; a reference does not constitute certification.
Getting started
Choose a Windows x64 installer, sign in with ChatGPT and create your KK-SOFT profile. When a trial build is available, Account issues a code you can paste into the app's license screen. The 30 days start at first activation. The website does not currently charge for trials.
If you already have a commercial KK-PDF Pro or KK-RAR license, choose the corresponding installer in Downloads. Annual and Lifetime licenses use separate release channels.
Account data and local files
The catalog, guides and notes are public. Account uses the verified sign-in identity. The trial server stores a profile identifier, edition, code hash and activation details needed to enforce trial limits. Your verified email is displayed in the session. KK-SOFT does not ask for a separate password or payment details.
PDF processing, archive operations and file scans run on the local machine for the selected workflow. Activation, updates and supported threat lookups use separate connections. Browser SHA-256 verification does not upload your file.
Release integrity
The release catalog records the exact version, size and SHA-256 of each installer. A trusted SHA-256 helps detect a changed or incorrect file. License and update signatures are separate controls; a public digest does not replace installer Authenticode.
