This Cookie Notice (the “Notice”) describes the details of cookies and other tracking technologies that SIGLENT (also referred to as “we”, “us” or “our”) uses on our websites (including: https://www.siglent.com/eu/, https://www.siglent.com/de/, https://www.siglent.com/fr/, https://www.siglent.com/it/ and https://www.siglent.com/es/, collectively, the “website”), as well as how you manage these cookies and tracking technologies.
A Cookie is a small text file that is saved by your browser and stored on your device (computer, tablet or smartphone). When you access a website, a cookie is placed on your device and it will send information to the party that placed the cookie. Cookies are placed either by Siglent – so-called “first party cookies” – or by third parties providing services to Siglent; such cookies are referred to as “third party cookies”. The cookies do not cause any damage to your computer and are generally deleted at the end of your session, unless they are so called persistent cookies. We and our third-party partners use cookies to make Siglent more user-friendly.
We may use other technologies that perform similar functions to cookies, such as tags, pixels, fingerprinting, web beacons, and similar script. These are often used in conjunction with cookies to help we understand our users better.
Information collected by cookies and tracking technologies can be personal data (information relating to an identified or identifiable natural person) or non-personal data. Personal data collected by cookies and tracking technologies may include, but is not limited to, your username and password, your IP address, and your browsing behavior. To find out more about our approach to privacy, please read our Privacy Policy.
Main contents of this Notice:
Web browser cookies may store information such as your IP address or other identifier, and information about the content you view and interact with on digital services. By storing such information, web browser cookies can remember your preferences and settings for online services and analyze how you use online services.
In addition to cookies, we may use local storage and similar browser-based technologies to store preference data (such as language settings) and to maintain session continuity. These technologies perform functions comparable to certain strictly necessary or functional cookies and are subject to the same legal bases and safeguards described in this Notice.
Tracking points may also be used. Tracking points are used to record device‑related information and user interaction behaviours for statistical analysis, with the aim of improving user experience and optimising website functionalities. Analysis is mainly carried out at aggregated group level and does not target specific individual users. Please note that certain tracking points may create device‑specific identifiers capable of recognising the same device across multiple website sessions.
We differentiates between strictly necessary cookies, analytical and performance cookies, functional cookies and advertising cookies depending on their function and intended purpose.
These cookies are absolutely necessary to provide the service, application, and other essential functionalities of Siglent. Without these cookies, functionalities cannot be ensured, for example that actions performed during a visit (e.g. text input) are preserved, also when navigating between individual pages of the website.
Strictly necessary cookies do not require consent from the user under applicable law, and you will not be able to reject these cookies in our cookies managing centre due to the essentiality surrounding their existence in Siglent. You may configure your web browser to block or delete these cookies, but you might then not be able to use Siglent’s functionalities as intended. To find out more about how to manage and delete cookies, please refer to 3.Manage and delete cookies.
Below we show a detailed list of the strictly necessary cookies we use on our website and the purpose for which we enable each tracker.
