Cookie Policy.
Last revised: January 2026 — Revision 01-B — Archive ref. CP-2026-01
What Cookies Are and Why This Site Uses Them
A cookie is a small text file placed on a visitor's device by a web server when a page is accessed. The file is stored locally by the visitor's browser and may be read by the originating server on subsequent visits. Cookies serve a range of functions: some are strictly necessary for a site to operate, while others support analytics, session management, or personalisation.
This website uses cookies in accordance with the EU ePrivacy Directive (2002/58/EC as amended by 2009/136/EC) and the General Data Protection Regulation (EU) 2016/679. Where cookies are not strictly necessary, Tralven obtains consent before placing them on a visitor's device. Consent is managed through the cookie banner displayed on first visit and may be reviewed at any time via the Cookie Settings link in the footer.
Tralven products are nutritional food-supplements registered with the applicable local regulatory authority under food-supplement classification. Products meet compositional and labelling requirements for nutritional supplement categories. No special-category personal data is collected through cookies on this site.
Categories of Cookies Used on This Site
Strictly necessary cookies are required for the technical operation of this website. They enable core functions such as session state, security, and load balancing. Without these cookies, services the visitor has requested cannot be provided. These cookies are set directly by Tralven's hosting infrastructure and are not used for tracking or profiling.
| Name | Purpose | Duration |
|---|---|---|
| PHPSESSID | Session identifier for server-side session state | Session |
| csrf_token | Cross-site request forgery protection for forms | Session |
| cookie_consent | Stores the visitor's cookie consent decision | 12 months |
Analytics cookies allow Tralven to understand how visitors interact with the website by collecting and reporting information anonymously. The data gathered includes pages visited, session duration, and navigation paths. This information is used solely to improve the editorial experience and content relevance of the site. No personally identifiable information is transmitted to analytics providers.
| Name | Provider | Duration |
|---|---|---|
| _ga | Google Analytics — distinguishes users | 24 months |
| _ga_* | Google Analytics — session state | 24 months |
| _gid | Google Analytics — distinguishes users per day | 24 hours |
Functional cookies enable enhanced features such as remembering visitor preferences across sessions and supporting third-party components embedded in the site (for example, mapping or font rendering services). Without these cookies, certain features of the site may not function as intended, but the core experience remains available.
| Name | Purpose | Duration |
|---|---|---|
| ui_preference | Stores viewport and display preferences | 6 months |
| maps_consent | Records consent for embedded mapping service | 12 months |
How to Review and Change Your Cookie Preferences
Consent for non-essential cookies may be withdrawn at any time. Three methods are available:
Cookie Settings Banner
Click the Cookie Settings link in the footer of any page on this site. The consent banner will reappear, allowing selection of a new preference level: Accept All, Accept Partial, or Functional Only.
Browser-Level Controls
All modern browsers provide controls for managing stored cookies. Cookies may be blocked entirely or deleted per domain through the browser's privacy settings. Note that blocking all cookies will prevent strictly necessary cookies from operating, which may affect the basic functionality of this site.
Third-Party Opt-Out Tools
For analytics cookies placed by third-party providers, opt-out tools are available directly from those providers. Google Analytics opt-out is available via the Google Analytics Opt-out Browser Add-on. These tools operate independently of the Tralven consent banner.
For questions about this Cookie Policy or about how Tralven uses cookies, please contact us at [email protected]. For the full account of how Tralven handles personal data, refer to the Privacy Policy.
Revisions to This Policy
This Cookie Policy may be updated to reflect changes in applicable law, in the cookies used on this site, or in the services provided by third-party providers. The revised policy will be published at this URL, and the revision date at the top of the page will be updated accordingly.
Where a revision is material — for example, where a new category of cookie is introduced or where a cookie's declared purpose changes — the cookie consent banner will be re-presented to visitors to obtain fresh consent for the updated category. The previous consent record will be retained in the archive alongside the policy revision under which it was obtained.
Continued use of this website after publication of a revised Cookie Policy constitutes acknowledgement of the revised terms. Questions and requests relating to cookies may be addressed to [email protected] or by post to ul. Hoza 38, 00-551 Warsaw, Poland.
