Legal & Technical Architecture

Privacy & Data Processing Disclosure

Factual overview of how technical project inquiries, analytics, and infrastructure security operate on this platform.

Operator Identity

Data Controller & Site Operator

This website functions as the independent professional practice of an AI Systems Architect & Consultant.

The operator of vitkovskyi.com is Valentyn Vitkovskyi, practicing as an independent AI Systems Architect & Consultant.

This page describes only genuine, verified technical mechanisms implemented within the site's architecture. It contains no placeholder boilerplate or speculative commitments detached from real software operations.

Inquiry Flow

Project Inquiry Data Handling

A strict minimal-collection policy designed solely to evaluate and respond to engineering inquiries.

When you complete and submit the inquiry form on the Work With Me page, only the information you deliberately provide is gathered:

  • Contact Credentials: Your full name and corporate/work email.
  • Organizational Context: Company or project name and optional links to supporting materials.
  • Technical Context: The core engineering problem, current system state, and desired outcome or deliverable.
  • Constraints: Expected timeline and optional budget context.

Purpose: This information is processed exclusively to qualify engineering challenges, evaluate architectural alignment, and formulate a technical response. Information is never used for advertising, newsletter marketing, behavioral profiling, or third-party syndication.

Storage Architecture: The website operates with no inquiry database. Upon successful submission, inquiries are dispatched via secure server notification directly to the operator's private mailbox. No copy of the message body is archived on the web server disk.

Security & Anti-Spam

Automated Abuse Prevention

Protecting communication channels without surveillance, third-party cookies, or invasive behavioral profiling.

To protect server infrastructure from automated bot traffic and spam, Cloudflare Turnstile (Managed Mode) is integrated alongside server-side verification.

Turnstile confirms legitimate human interaction without setting third-party tracking cookies across websites and without requiring interactive image-labeling puzzles.

Traffic Measurement

Privacy-First Aggregate Analytics

Independent measurement designed without cross-site trackers or user fingerprinting.

This site is configured for Plausible Analytics exclusively in production environments. Analytics scripts are completely disabled in development, preview, and local test builds.

Plausible operates under privacy-by-design standards:

  • No cookies are used (cookie-less architecture).
  • No persistent user or device identifiers are generated.
  • No Personally Identifiable Information (PII) is gathered.
  • Inquiry form messages, names, and email addresses are strictly never sent to analytics.
Infrastructure

Server Logs & Rolling Rate Limiting

System stability controls engineered with one-way cryptographic hashing.

To prevent denial-of-service abuse and mail server flooding, the inquiry endpoint implements a privacy-preserving rate limiter.

Visitor IP addresses are never stored in raw plaintext. Requests are tallied against a one-way HMAC-SHA256 digest keyed with a secret server salt. Temporary rate-limit tokens are automatically purged after the rolling 60-minute window expires.

Standard HTTP web server access logs are retained at the hosting infrastructure level strictly for technical diagnostics and security audits.

Inquiries

Privacy Questions & Communications

Direct communication channel for privacy-related technical inquiries.

For inquiries regarding these data practices or technical disclosures, please initiate contact via the Work With Me inquiry form, noting your privacy topic in the problem description.
