1. General Provisions & Privacy-by-Design Architecture

This Privacy and Cookie Policy (“Policy”) explains how technical information and cookies are handled when you visit the PROSTO24 IT & Engineering Portal (https://prosto24.com). Last updated and effective date: October 12, 2026.

PROSTO24 is engineered around strict data minimization principles (Privacy by Design). When you read articles or use our interactive engineering calculators (VRAM estimator, Cloud vs. GPU ROI calculator, Password Entropy analyzer, CLI builder), all computations execute locally inside your browser via client-side JavaScript without transmitting your inputs to external servers.

2. Anonymous User Accounts & Community Discussions

To enable commenting and article bookmarking without compromising reader privacy, PROSTO24 operates a zero-PII account system:

  • We do not require or collect your real name, phone number, physical address, or personal identity documents to register;
  • Accounts are provisioned with a randomized identifier (user_xxxxx) and a cryptographic session credential;
  • Submitted comments undergo automated spam filtering and editorial moderation to maintain technical discussion quality.

3. How We Use Cookies & Browser LocalStorage

PROSTO24 uses standard HTTP Cookies and browser localStorage for the following legitimate purposes:

  • Essential & Functional Storage: remembering your selected interface language (English / Russian), dark or light theme preference, saved article bookmarks, and your cookie consent choices;
  • Performance & Analytics Cookies: measuring aggregated, anonymized page views and reading engagement so our editorial team can improve technical guides and site speed;
  • Advertising Cookies: delivering relevant contextual advertisements and capping ad frequency across sessions.

4. Google AdSense & Third-Party Advertising Cookies Disclosure

To keep our engineering guides and interactive calculators free for all readers, PROSTO24 partners with third-party advertising networks, including Google AdSense. In compliance with Google AdSense Program Policies and the EU User Consent Policy, please note the following mandatory disclosures:
