This website, deepchain.bio (the “Website”), and the deepchain web application, accessible via subdomains of deepchain.bio (the “App”), are operated by InstaDeep Ltd (alternately, “InstaDeep”, “we”, “us” or “our”). This policy covers cookies and similar storage technologies used across both the Website and the App (“cookies”).
What are cookies?
Cookies are small text files that are placed on your computer by websites that you visit. This policy also covers similar storage technologies, including Local Storage and Session Storage, which serve comparable purposes. These technologies are widely used in order to make websites work, or work more efficiently, as well as to provide information to the owners of the site. Included below are tables, setting out what cookies we use, and the purposes for which we use them.
Cookies might be used for the following purposes:
- To enable certain functions
- To provide analytics
- To store your preferences
- To enable ad delivery and behavioral advertising
What kind of cookies are used on the Website and App?
Our Website and App uses session cookies, persistent cookies, and third-party cookies.
A session cookie is used to identify a particular visit to our Website and / or App. These cookies expire after a short time, or when you close your web browser after using our Website and / or App. We use these cookies to identify you during a single browsing session, such as when you log into our Website or App.
A persistent cookie will remain on your devices for a set period of time specified in the cookie. We use these cookies where we need to identify you over a longer period of time. For example, we would use a persistent cookie if you asked that we keep you signed in.
How do we categorise cookies and storage technologies?
We group cookies and storage technologies into the following consent categories:
- Essential: Required for the website to function. These do not require consent and cannot be disabled. Includes our consent management platform (Osano), authentication (Auth0), and security features (Cloudflare, reCAPTCHA).
- Analytics: Help us understand how visitors use our website. These require your consent via our cookie banner. Includes Google Analytics and VWO.
- Marketing: Used to track visitors and deliver relevant content or advertisements. These require your consent via our cookie banner. Includes HubSpot and YouTube.
What third-party technologies do we use?
We use Third Party cookies from Google Analytics, Auth0, Osano, HubSpot and VWO. If you click on a hyperlink from our services to any third-party websites, you may be sent cookies from these third-party websites.
As these are third party providers, we do not control the use of these cookies and cannot access them or the data they may contain.
Third-party websites will have their own privacy and cookie policies. Please check the third-party websites for more information about their cookies and how to manage them. Disabling these cookies will likely break the functions offered by these third parties, such as Youtube Video Embeds.

It also collects login data including IP address, browser type, and device type to prevent unauthorized access. Auth0 also has access to authentication-related usage data for the App (such as login activity) to help monitor sign-in activity, detect misuse, and improve the reliability and security of access.
