1. INTRODUCTION

This notice (“Cookie Notice”) explains how Meta Platforms Ireland Limited (“Meta” or “we”), the data controller responsible for the use of cookies on this site, uses cookies on the Engineering at Meta website (“Services”). The notice also sets out how you can manage your cookie settings and withdraw your given consent in relation to the use of cookies and other technologies.

We encourage you to read this Cookie Notice closely. If you have any questions in this regard or otherwise in relation to our handling of cookies and other technologies, please don’t hesitate to contact us by using the contact details in Section 6.

If you want to have more information on how we process your personal information, please read our Privacy Notice.

2. WHAT ARE COOKIES?

A cookie is a small text file that is placed on your device when you visit a website or use an application. Cookies are widely used to make websites or mobile applications work or to improve their efficiency, as well as to provide a better experience, for instance by allowing the website or mobile application to recognize when a visitor returns to the website. When we talk about cookies in this Cookie Notice, this term also includes these similar technologies such as pixel tags and web beacons.

First-party cookies refer to cookies that we have placed on your device when you use our Services.

Third-party cookies refer to cookies that another party has placed on your device when you use our Services.

Permanent cookies refer to cookies that remain on your device when our Services are closed but are to be used on subsequent visits to or uses of our Services.

Session cookies refer to cookies that are temporary and disappear after our Services are closed.

3. THE PURPOSES FOR WHICH WE USE COOKIES

We use essential cookies for the site to work as intended. We set optional site analytics cookies only after you choose to allow them. Advertising pixels and social media tracking tags are disabled. Third-party embedded video players are described below.

Essential cookies are required for the site to work as intended and to remember your cookie choice. They remain in use when you decline optional cookies.

Optional site analytics cookies help us understand how people use this site and measure the performance of its content. They are set only after you allow them.

OTHER BROWSER STORAGE AND EMBEDDED MEDIA

In addition to cookies, the site and embedded players use the browser storage described below. Local storage and IndexedDB persist until they expire, the provider removes them, or you or your browser clear them. Session storage lasts for the browser tab’s session. These items are separate from the optional Google Analytics cookies above.

Some pages include YouTube videos provided by Google. We use YouTube’s privacy-enhanced player. Views through this player are not used to personalize your YouTube experience or advertising outside this site. YouTube may still show non-personalized ads. The player can use the browser storage listed above even when optional site analytics is off. Storage use and retention can depend on player features, your browser and your existing provider settings.

Some pages include Libsyn audio players. Loading or playing these sends requests to Libsyn’s player and audio delivery services. No additional cookies or browser storage were identified in the embedded player configuration used by this site during load and playback checks.

Social media content and Knight Lab timelines are provided as links to their original sites instead of embedded tracking services. Following these links opens another site whose own cookie and privacy choices apply.

THIRD-PARTY COOKIE PROVIDERS

Google provides the optional site analytics service. Learn how Google uses information from sites that use its services and read Google’s Privacy Policy.

Google also provides the YouTube embedded player. Read about YouTube’s privacy-enhanced mode and Google’s use of cookies and similar technologies.

4. HOW TO MANAGE COOKIES

You can refuse optional site analytics cookies by clicking “Decline optional cookies” in the Cookie Banner. Clicking “Allow all cookies” enables the optional site analytics cookies listed above. Essential cookies remain in use to provide the site and remember your choice.

You can review or change your choice and withdraw consent at any time on the Settings page. Turning the optional site analytics control off stops site analytics and removes existing site analytics cookies that this site can access. Turning it on allows these cookies.

If you decline or withdraw consent, we will be unable to perform site analytics on this site using such cookies and similar technologies. You can continue to use the site. Your choice applies to this site on this browser and is remembered for 180 days (approximately six months). Clearing the preference cookie will show the banner again. Your browser may shorten the storage periods listed in this notice.

The Settings page controls optional site analytics cookies. Declining these cookies does not disable embedded media players or the technical emoji support cache. Embedded players can connect to their provider while site analytics is off. This site cannot remove cookies or browser storage on a media provider’s domain; the provider information and browser controls below explain the additional choices available to you.

Use the Cookie Banner or the Settings page above to allow or refuse optional cookies and to withdraw consent. Browser settings are additional controls; they do not replace these choices or provide consent to optional cookies on this site. You can also use them to block or delete cookies.
