Privacy policy
Cookiebannerbench is a published benchmark, not a product. This policy explains the limited information processed when you visit cookiebannerbench.com and how we use cookies and similar technologies.
Last updated23 September 2026
Data controller
CookieYes Limited is the data controller for Cookiebannerbench and cookiebannerbench.com. Our registered address is 3 Warren Yard Warren Park, Wolverton Mill, Milton Keynes, MK12 5NW, United Kingdom. Our representative in the European Union is Euverify Ltd, Cork, Ireland.
This policy covers this website only. It does not cover the CookieYes product or any other CookieYes website, each of which has its own policy. It also does not apply to data processed on a customer's behalf where CookieYes acts as a processor rather than a controller.
Personal data we collect
We do not ask you to provide personal data directly. The site has no account system, contact form, newsletter, comments or payment facility. We do not ask for your name, email address or payment details.
Our hosting provider records standard server log data when your browser requests a page. That log typically contains:
- The IP address from which the request originated.
- The date and time of the request.
- The page or file requested and the response status.
- The browser user-agent string and, where sent, the referring page.
An IP address may be personal data under the UK GDPR and EU GDPR. We do not combine server-log information with other information to build a profile or attempt to identify you.
Legal basis for processing
We rely on our legitimate interests under Article 6(1)(f) of the UK GDPR and EU GDPR to process server logs and operate, secure and improve the site. These interests include keeping the site available, diagnosing faults and protecting it against abuse.
Where applicable law requires consent before we store or access optional cookies or similar technologies, we rely on that consent. You may withdraw it at any time through the cookie controls made available on the site.
Cookies and local storage
We use cookies and similar browser technologies. Cookies are small text files placed on your device when you visit a website. Some last only for the browser session; others remain until they expire or you delete them. The technologies used on this site may include:
- Necessary storage: used to provide the site, protect it and remember your privacy choices.
- Preference storage: used to remember settings you choose, such as the site's appearance.
- Measurement storage: used, where enabled and with consent when required, to understand aggregate use and improve the benchmark.
The current site also stores the localStorage value cookiebannerbench-theme, which remembers whether you chose the light or dark theme. The value stays in your browser, contains no identifier and is removed when you clear site data or return the theme to "system".
You can use the site's cookie controls, where displayed, to accept or reject optional categories and change your choices later. You can change or withdraw your consent at any time by selecting the floating “Revisit consent” button, shown on every page. This reopens the preference panel, where you can enable or disable optional cookie categories and save your updated choices.
You can also block or delete cookies in your browser settings, although doing so may prevent preferences or parts of the site from working as intended. Necessary technologies cannot always be disabled through our controls because they are required to provide the site.
Disclosure of personal data
We do not sell or rent personal data, and we do not use it for targeted advertising. Vercel Inc., our hosting provider, processes request and server-log data on our instructions to serve and protect the site. Where we enable measurement, we do so only with your consent. Where you consent to measurement (that is, where you consent to the analytics cookie category), the relevant service provider may process cookie identifiers and usage information on our behalf.
We may disclose data where required by law or where necessary to establish, exercise or defend legal claims.
International transfers
The site is served from a global content delivery network, so a request may be handled by a server outside the United Kingdom or European Economic Area. Where data is transferred outside the UK or EEA, we use an applicable safeguard, such as an adequacy decision, the European Commission's standard contractual clauses or the UK International Data Transfer Addendum.
Data retention
We do not maintain an account or customer database for this site. We keep personal data only for as long as needed for the purposes described in this policy, including security, troubleshooting and legal compliance. Cookies and similar technologies remain for the duration stated in the cookie controls or until you delete them. Server-log retention is determined by our hosting configuration and may be extended where needed to investigate a security incident or comply with law.
Data security
The site is served over HTTPS. We use appropriate technical and organisational measures designed to protect the limited information processed through the site. No method of transmission or storage is completely secure. The source of every page and the measurement data behind every benchmark number are public in the project repository.
Links to other websites
This site links to the websites of the consent providers it measures, the project source repository and npm. Those sites set their own cookies and have their own privacy policies, over which we have no control. This policy applies only to Cookiebannerbench.
Your legal rights
Depending on the law that applies to you, you may have the following rights in relation to personal data we hold about you:
- Access: request a copy of your personal data and check that it is processed lawfully.
- Rectification or deletion: ask us to correct inaccurate data or delete data where the law permits.
- Restriction: ask us to limit how your personal data is processed.
- Objection: object to processing based on our legitimate interests.
- Portability: request eligible data in a structured, commonly used and machine-readable format.
Because this site has no accounts, we may be unable to link technical records to you without additional information. If you can identify the relevant requests (for example, by providing an IP address and approximate time), we will consider and respond to your request in accordance with applicable law.
