Cookie Policy

This policy explains how Tetra Software Company LTD uses cookies and similar technologies on the website, and how you can control them.

Last updated: June 10, 2026.

1. What are cookies?

Cookies are small files stored on your device when you visit a website. They help remember your choices, measure traffic and improve your experience.

2. Cookie categories we use

• Necessary (always on): keep the website working and remember your choices. Cannot be turned off.
• Analytics: we use a self-hosted, cookieless analytics tool (Umami) to measure anonymized visits — no analytics cookies are set on your device.
• Marketing/advertising: we currently use NO marketing cookies and NO third-party tracking pixels.

3. Third-party cookies

Because our analytics tool (Umami) is cookieless and self-hosted, the website sets almost no third-party cookies. We do not use advertising pixels (such as Google Ads or Meta Pixel). The Google Search Console we use for SEO is a webmaster tool that sets no tracking cookies on the website. If this changes, we will update this policy and add an appropriate consent mechanism.

4. Why there is no cookie consent banner

Because the website uses no non-essential tracking cookies, we do not display a cookie consent banner. Instead, we show a transparent notice about how we handle data. If we ever use non-essential cookies, we will add an appropriate consent mechanism.

5. Managing cookies

You can delete or block cookies through your browser settings at any time. Note that blocking necessary cookies may affect how the website works.

6. Changes to this policy

We may update this policy; the latest version is posted on this page with its update date.
