Syncfusion Cookies and Tracking Notice

Effective May 2026

What is a Cookie

Cookies are small text files created when your web browser loads a particular website. These text files are sent to your browser from websites you visit and downloaded to the computer or mobile device you are using to access such sites. Later, cookies are sent back to the site each time you visit it, or to other sites that recognizes these cookies.

Opting Out

Disclaimer: You will not be able to opt out of strictly necessary cookies. If you set your browser or device to refuse cookies, you may not be able to use all the features of the Syncfusion website.

Managing Cookies Preferences in Your Browser

Most browsers contain options which allow you to manage whether to allow websites to accept cookies and to clear cookies and browsing data. For example, Google Chrome’s settings at chrome://settings/cookies allow you to delete existing cookies, allow or block all cookies, and set cookie preferences for websites. Google Chrome also offers Incognito mode, which deletes your browsing history and clears cookies from the Incognito windows on your device after you close all of your Incognito windows.

Managing Cookies Preferences on a Mobile Device

Many mobile devices and applications offer options to manage similar technologies, like unique identifiers used to recognize an app or device. For instance, on Android devices, you can control the Advertising ID, while on Apple devices, you can manage the Advertising Identifier in your device settings. Additionally, app-specific identifiers can often be managed within the app’s settings.

Your mobile operating system may also provide additional choices to opt out of interest-based advertising or reset your mobile identifiers. For instance, on iOS devices, you can utilize the “Allow Apps to Request to Track” setting, while on Android devices, you can use the “Opt out of Interest-Based Ads” setting. These settings empower you to restrict the use of information about your app usage for the purpose of serving personalized ads based on your interests.
