AiCNC is desktop software. For license activation and license management,
AiCNC processes limited technical information as described below.

AiCNC does not collect or upload your machining programs, NC files, drawings,
images, computer name, or other user files for license activation. If you
choose to connect an AI service in the AI assistant, parts of the open NC
program are sent directly to that AI service, as described in Section 6.


1. INFORMATION PROCESSED
------------------------
When AiCNC is activated, or registered for a trial, the following information
may be processed:

  - Hardware identification hash
      A SHA-256 hash generated from selected hardware and system identifiers
      of the computer, such as the Windows MachineGuid, CPU information,
      system-volume serial number, BIOS UUID, and motherboard serial number.
      The original hardware and system identifiers are NOT transmitted to the
      activation server; only the resulting SHA-256 hash is transmitted.

  - License key
      The license key entered by the user for activation.

  - Application version
      The AiCNC version, transmitted for license management and support.

  - Activation or trial-registration time
      The time associated with an activation or an initial trial
      registration may be transmitted and stored.

  - Update and version check (on startup)
      On startup, AiCNC may contact the license server to check for a newer
      version. In doing so it transmits the hardware identification hash, the
      license key if one is present (otherwise none), the application version,
      edition, and license status. The server additionally records the
      originating network (IP) address and the approximate location derived from
      it (country, region and city). This check does not transmit your name, files, or machining programs,
      and does not prevent AiCNC from running when the computer is offline or
      the server is unreachable.


2. PURPOSE OF PROCESSING
------------------------
The information above is processed to:
  - activate and validate AiCNC licenses;
  - manage authorized license activations;
  - register and manage trial use;
  - notify you when a newer version is available;
  - detect license sharing and unauthorized or unlicensed use (including by
    reference to the originating IP address and approximate location); and
  - prevent unauthorized use of the software.


3. TRANSMISSION AND STORAGE
---------------------------
License activation and trial-registration information is transmitted to and
stored on the license server operated by the Publisher, and is used for
license activation, license and trial management, and related technical
support.


4. RETENTION AND DELETION
-------------------------
  - Active license records are retained while the corresponding license
    activation remains active. For a perpetual license, the activation record
    remains stored as long as the activation remains active.

  - When an activation is deactivated, the corresponding active activation
    record is deleted immediately. Activation records are also deleted when
    the associated license is revoked.

  - Records of activation changes are retained for up to five (5) years for
    license administration, enforcement of activation limits, fraud
    prevention, and dispute resolution, and are deleted thereafter.

  - Trial-registration records are retained for up to five (5) years for trial
    management and to prevent repeated or unauthorized trial registrations, and
    are deleted thereafter.

  The retention periods above are applied only for the purposes described in
  this Notice, and are the Publisher's own operating policy (not a statutory
  minimum). When the applicable period expires, the relevant records are
  deleted unless continued retention is required or permitted by applicable
  law.


5. PRIVACY RIGHTS AND CONTACT
-----------------------------
You may contact the Publisher regarding questions or requests concerning the
information described in this Notice. Requests are handled in accordance with
applicable law.

6. AI ASSISTANT (OPTIONAL)
--------------------------
The AI assistant is off unless you connect an AI service yourself. When you
connect one (for example an AI agent installed on your computer, or an AI
service address and key such as Google Gemini, OpenAI GPT or xAI Grok):

  - What is sent: your messages to the assistant, and the parts of the open
    NC program that the AI requests to answer them - for example NC lines,
    the G/M codes used, the program overview (machine name, tools, line
    count) and the results of the simulator's checks.

  - Where it goes: directly from your computer to the AI service you chose,
    under your own account or key. It is NOT sent to, through, or stored on
    the Publisher's servers, and the Publisher does not receive it.

  - How the AI service handles it: under that service's own terms and privacy
    policy, which you accept with that service. Some services, including some
    free plans, may keep or use submitted content to improve their models.
    Check your AI service's terms before sending confidential programs.

  - API keys you enter are stored only on your computer, encrypted for your
    Windows user account (Windows DPAPI), and are sent only to the address
    you entered.

  - The AI cannot open files on your computer through AiCNC; it can only use
    the AiCNC assistant functions. Changes it proposes to your program are
    applied only when you approve them.

You can disconnect the AI service at any time. Nothing is sent while it is
not connected.


CHANGES TO THIS NOTICE
----------------------
This Privacy Notice may be updated when necessary to reflect changes to AiCNC,
its license activation system, or applicable law. The Effective Date above
identifies the current version. The Publisher's full privacy policy, where
provided, is published on the Publisher's website.
