This Cookie Policy explains how Zyverna, Inc. ("Zyverna", "we") uses cookies and similar technologies on https://zyverna.com and in the Zyverna application. It should be read together with our Privacy Policy.
1. What are cookies?
Cookies are small text files placed on your device by a website. They are widely used to make websites work, remember preferences and provide information to site owners. We also use similar technologies such as local storage, session storage and pixels; this policy refers to all of them as "cookies".
2. How we use cookies
We group cookies into the following categories.
2.1 Strictly necessary (always on)
Required for the Service to function and cannot be switched off. They are set in response to actions you take such as signing in, setting privacy preferences or filling in forms.

3. Your choices
- Consent banner. On your first visit we ask for your choice. You can accept all, reject non-essential cookies or manage categories individually.
- Change your mind. Open Cookie settings in the site footer or clear the
zy_cookie_consent_v1entry in your browser to see the banner again. - Browser controls. Most browsers let you block or delete cookies. Blocking strictly necessary cookies will prevent you from signing in.
- Global Privacy Control. We treat a GPC signal as a rejection of analytics and marketing cookies where required by law.
4. Third-party cookies
Some cookies are set by third parties (e.g., Stripe during checkout, identity providers during sign-in). We do not control these cookies; please refer to the third party's own policy.
