This page explains how ZVM Labs handles privacy, data, external services, and content. It is written in plain language for a personal technical blog, but structured like a basic privacy notice: who runs the site, what data may be processed, why it may be processed, on what basis, and how you can contact ZVM Labs about your data.

This is not legal advice. If you need a formal legal review for an organization, regulatory audit, or contractual compliance, consult a qualified legal professional.

Short Version

  • ZVM Labs does not require user accounts.
  • The site does not provide payments, private dashboards, or comments.
  • The feedback form does not store messages on the website server: it prepares an email in your email client.
  • If you send an email, you voluntarily provide your name, reply address, and message content.
  • The site may use browser technical data, localStorage, or server logs for functionality and security.
  • Blog content is educational and is not legal, financial, or professional security advice.

ZVM Labs is a personal blog and does not claim formal certification or full regulatory compliance for every jurisdiction. However, this policy is prepared with reference to general principles from:

These links are provided as professional references. Whether a specific document applies depends on jurisdiction, data type, user location, hosting setup, and the specific processing scenario.

ZVM Labs does not sell personal data and does not use it for advertising profiling.

Retention

Data is kept no longer than necessary for the relevant purpose:

  • emails - for the time needed to reply, preserve communication context, or protect against spam;
  • technical logs - according to hosting policies and security needs;
  • localStorage - until you clear browser data or change browser settings;
  • security report records - as long as needed to verify, fix, and document the issue.

If a specific message or request is no longer needed, you may ask for its deletion.

What Data May Be Processed

Data You Voluntarily Send

If you contact ZVM Labs by email or through the Feedback page, the following data may be processed:

  • name or preferred way to address you, if provided;
  • reply email address;
  • message topic;
  • message content;
  • any other information you choose to include.

Do not send passwords, private keys, access tokens, identity documents, employer-confidential information, or third-party personal data unless you have a lawful basis to do so.

Technical Data

Like most websites, ZVM Labs may indirectly involve technical data through hosting, browsers, or system logs:

  • IP address;
  • browser User-Agent;
  • request date and time;
  • requested URL;
  • server response code;
  • basic access error information.

This data is used for site operation, troubleshooting, and basic security.

Cookies and localStorage

ZVM Labs does not use cookies for advertising or tracking profiles.

The site may use browser localStorage for technical convenience:

  • saving the selected visual theme;
  • saving menu scroll position;
  • supporting interface behavior.

This information stays in your browser and is not intended to identify you personally.

Analytics

As of the last update of this page, ZVM Labs does not declare advertising analytics or behavioral tracking.

The site technically supports an optional article view counter through a privacy-friendly analytics provider. If this counter is enabled in the site configuration, it may process request metadata, page URL, referrer, user agent, or shortened IP information according to the provider’s own policy. The counter is intended for aggregated article view statistics, not advertising profiling.

If analytics are added in the future, this page should be updated to explain:

  • which service is used;
  • what data is collected;
  • why it is collected;
  • how tracking can be limited or disabled.

The site links to third-party platforms, including GitHub, LinkedIn, Telegram, YouTube, TryHackMe, HackTheBox, pwn.college, X, and Facebook.

When you open an external site, that platform’s privacy and security rules apply. ZVM Labs does not control how third-party services process your data.

International Data Transfers

Because email, hosting, social platforms, and external services may rely on infrastructure in different countries, your data may technically be processed outside your country of residence.

ZVM Labs does not organize a separate commercial transfer of personal data to third parties, but email providers, hosting providers, and external platforms may conduct their own international processing under their own policies.

Feedback and Email

The Feedback page prepares an email through mailto:. This means:

  • the message is not stored in a ZVM Labs database;
  • sending happens through your email client or email provider;
  • after sending, the message is stored in the sender’s and recipient’s email systems.

Emails may be retained as long as needed to reply, discuss ideas, keep agreed context, or protect against spam and abuse. If you want a message deleted, contact [email protected].

Content Policy

ZVM Labs publishes educational material about cybersecurity, programming, systems and network administration, AI workflows, GRC, risk management, and technical management.

Content principles:

  • explain context and scope;
  • show evidence where appropriate;
  • do not encourage illegal activity;
  • do not publish private data, secrets, tokens, or access credentials;
  • do not present learning notes as professional consulting;
  • separate facts, assumptions, and personal conclusions.

Cybersecurity materials are intended for learning, defense, risk analysis, and responsible practice.

AI Policy

AI tools may be used for learning, note structuring, text editing, idea analysis, or draft preparation.

ZVM Labs principle: AI may assist, but it does not replace author responsibility. Technical claims, practical conclusions, and recommendations should be checked before publication.

Security Policy

If you find a technical issue on the site, report it to [email protected].

Please:

  • do not perform aggressive scanning;
  • do not attempt unauthorized access;
  • do not disrupt the site;
  • do not publicly disclose a potential vulnerability before coordination.

Responsible reporting is welcome.

You may contact ZVM Labs to request:

  • clarification about data you sent by email;
  • correction of contact information;
  • deletion of a previous message;
  • withdrawal of consent for further communication;
  • review of a specific publication or mention;
  • restriction of further communication;
  • objection to further processing, where applicable.

Depending on applicable law, you may also have rights of access, correction, deletion, restriction, objection, and data portability.
