Your data, your rules.
We use cookies to keep Serus running smoothly and to understand how we can make it better. Some are essential (like keeping you logged in), others help us improve the experience or measure what's working.
You're always in control — you can adjust your preferences anytime. This page explains exactly what we use, why, and how to change it.

4. How you control cookies
We use the categories below. Exact cookies may change over time.
4.1 Cookie banner / preferences
When you first visit our website (and periodically thereafter), you will see a cookie banner that allows you to accept or reject non-essential cookies, or customize your preferences.
You can update your preferences at any time through pressing the cookie widget in the bottom left corner of this page.
4.2 Browser controls
Most browsers allow you to control cookies through settings. You can:
•
delete existing cookies
•
block cookies
•
set your browser to alert you before cookies are stored
Blocking strictly necessary cookies may cause the Services to stop working properly.
4.3 Cookies and account registration
When you create an account or sign in to the Services, we set strictly necessary cookies required for authentication, session management, and security. These cookies are essential for the Services to function and do not require your consent.
During account registration, you are asked to acknowledge and agree to our Terms of Service, Privacy Policy, and the use of cookies for analytics and advertising purposes. By checking the consent checkbox and completing registration, you consent to the activation of analytics and advertising cookies as described in this Cookie Policy.
If you have previously set cookie preferences through our cookie banner (for example, by declining non-essential cookies while browsing our website before registering), those preferences will be respected and carried forward into your account. In that case, non-essential cookies will not be activated upon registration, regardless of the registration consent checkbox.
You can update your cookie preferences at any time through the cookie preferences widget (available in the bottom left corner of our website), your account settings (where available), or your browser settings. Withdrawing consent for non-essential cookies will not affect your ability to use the Services.
4.4 Do Not Track
Some browsers offer “Do Not Track” signals. Because there is no consistent industry standard, we do not respond to Do Not Track signals in a uniform way. We continue to provide choices through our cookie banner and settings.
5. Cookies used by service providers (subprocessors)
We use third-party service providers (subprocessors) for functions like hosting, analytics, payments, customer support, and security. These providers may set cookies or use similar technologies when you use the Services.
See our Subprocessors list:https://www.serus.ai/legal/subprocessors
6. International data transfers
Because we operate globally, cookie-related data (like IP addresses and device identifiers) may be processed in countries outside your jurisdiction, including the United States. Where required, we use appropriate safeguards such as Standard Contractual Clauses, as described in our DPA.
DPA: https://www.serus.ai/legal/dpa
7. Updates to this Cookie Policy
We may update this Cookie Policy from time to time to reflect changes in law, technology, or our practices. We will post updates on this page and revise the “Last updated” date. Material changes may also be communicated through the Services or via other notice where required by law.

The cookies and similar technologies we use may change over time as we update our Services, improve performance, add features, or change vendors.
