Version 1.0 – 12 September 2026. In case of any difference between the language versions, the English version prevails.
This policy describes the cookies and similar technologies used on www.adtyre.com and on the supplier portal onboarding.adtyre.com, what they are for, how long they last, and how you can control them. It complements our Privacy Policy, which names the controller and explains your rights.
1. What cookies and similar technologies are
A cookie is a small text file that a website stores in your browser. It is sent back to the site on each visit, which lets the site recognise your browser, keep you signed in, or remember a choice. Browsers also offer local storage and session storage, which store information on your device without sending it to the server. We describe both in this policy.
Under European law, technologies that are strictly necessary to provide a service you asked for, or that only store your own preferences, can be used without your consent. All others, in particular those of third parties, require your prior consent.
2. Cookies on www.adtyre.com
Our corporate website uses no audience measurement tool, no advertising cookie and no social media tracker. The fonts used by the site are served from our own server, not from Google. The only technology that requires your consent is the YouTube video player.
2.1 Necessary cookies (no consent required)
| Name | Set by | Purpose | Duration |
|---|---|---|---|
| pll_language | www.adtyre.com (Polylang) | Remembers the language in which you read the site. | 1 year |
| cmplz_consented_services, cmplz_functional, cmplz_marketing, cmplz_statistics, cmplz_preferences, cmplz_banner-status, cmplz_policy_id, cmplz_id | www.adtyre.com (Complianz) | Record the choices you made in the cookie banner, so that we do not ask you again and so that we respect your refusal. | 6 months |
The contact and claim forms, and the mathematical anti-spam question that protects them, set no cookie.
2.2 Marketing cookies (only with your consent): YouTube
Some pages include a background video hosted on YouTube. If you accept “Marketing” cookies in the banner, the YouTube player provided by Google is loaded, and Google may set cookies and local storage in your browser, in particular:
| Name | Set by | Purpose | Duration |
|---|---|---|---|
| VISITOR_INFO1_LIVE | youtube.com | Measures the player’s bandwidth and, according to Google, may serve personalisation and advertising purposes. | 6 months |
| YSC | youtube.com | Records a unique identifier for video statistics during the session. | Session |
| VISITOR_PRIVACY_METADATA | youtube.com | Stores the privacy status Google assigns to your visit. | 6 months |
| PREF | youtube.com | Stores player preferences. | 8 months |
| __Secure-ROLLOUT_TOKEN and other __Secure-* cookies | youtube.com | Used by Google for security and feature deployment. | Up to 6 months |
| yt-remote-* and yt-player-* (local storage) | youtube.com | Store player settings on your device. | Until deleted |
The data collected through the player is processed by Google Ireland Limited and Google LLC as controllers for their own purposes, and may be transferred to the United States under the EU-U.S. Data Privacy Framework. You can read Google’s privacy policy and Google’s cookie information. If you refuse, the pages display a still image instead of the video, and nothing is sent to Google.
2.3 Your choice and how to change it
On your first visit, a banner lets you accept all, refuse all, or customise your choice by category. Refusing is as easy as accepting, and browsing continues normally either way. Your choice is stored for 6 months; after that, we ask you again. You can change your mind at any time with the “Manage cookies” link at the bottom of every page, which reopens the banner.
3. Cookies on onboarding.adtyre.com (supplier portal)
The Portal uses only technologies that are strictly necessary to authenticate you and to secure your account. It contains no third-party script, no analytics tool and no advertising. For that reason, the Portal shows no cookie banner: nothing on it requires your consent.
| Name | Type | Purpose | Duration |
|---|---|---|---|
| supplier_session | Cookie (HttpOnly, Secure, SameSite=Strict) | Keeps you signed in during your session. It contains a random token; only a hash of it is stored on our server. | 12 hours, or until you sign out |
| __Host-supplier_trusted_device | Cookie (HttpOnly, Secure, SameSite=Strict) | If you enabled two-factor authentication and chose “trust this device”, lets you skip the second factor on this browser. | 14 days |
| adtyre-onboarding-language | Local storage | Remembers the language you selected on the sign-in screen. | Until you clear your browser data |
| document-reply-notifications:<your user id> | Local storage | Remembers which document notifications you have already dismissed, so that they are not shown again. | Until you clear your browser data |
| onboarding-admin-return-locale | Session storage | AD TYRES administrators only: restores their language after they have viewed the Portal on behalf of a supplier. | Until the browser tab is closed |
Blocking the session cookie in your browser prevents you from signing in to the Portal.
4. Managing cookies in your browser
Independently of our banner, you can delete or block cookies in your browser settings. Here is how for the main browsers:
Blocking all cookies may prevent some features from working, in particular signing in to the Portal.
5. Questions and changes
Questions about cookies can be sent to our Data Protection Officer at dpo@adtyre.com. We update this policy whenever we add or remove a technology; the version and date appear at the top.
