Cookie policy
The catalogue works without analytics, advertising or personalisation cookies. Only functions requiring state use strictly necessary technologies.
Last updated: 2026-08-31Public catalogue without cookies
Catalogue, product, knowledge, comparison and information pages do not start a session. They currently load no Google Analytics, Microsoft UET, advertising pixels, social plug-ins or third-party tag managers, so no consent banner is needed there.
XSRF-TOKEN
First-party, strictly necessary encrypted token created for the contact form or another stateful function to prevent forged submissions. It expires after approximately 120 minutes and is not used for tracking.
tadna-session
First-party session cookie used for form state, confirmation messages, session-based language choice and private-area authentication. It ordinarily expires after 120 minutes of inactivity, uses SameSite=Lax and is HTTP-only where appropriate. Staff choosing “remember me” may receive the authentication system’s functional remember cookie.
Browser session storage
The administration area uses sessionStorage with a key beginning “tadna:research-detail-tab:” to remember the open research tab. It stores only a route and interface choice within the browser tab and is not used for cross-site tracking.
Third-party retailers
Showing an Amazon, eBay or other retailer link does not set that retailer’s cookies on Tadna. After you leave, the destination may set its own cookies and receive connection data under its policy.
Consent
The listed technologies support a requested function and fall within the strictly necessary exception. If non-essential analytics, advertising or personalisation is added, it will remain off until valid affirmative consent and equivalent accept, reject and withdraw controls are available.
Browser controls
You can inspect, block or delete cookies in browser settings. Blocking required cookies will not prevent reading the catalogue but can break contact, language preference or administration.
