What Are Cookies?
Cookies are small text files placed on your device by websites you visit. They are widely used to make websites work efficiently, provide a better user experience, and supply information to site owners. Cookies can be "persistent" (remaining on your device until deleted) or "session" (deleted when you close your browser).
How We Use Cookies
Expona uses a limited number of cookies to operate the Service and understand how visitors interact with our website. We categorize our cookies into two types:
Essential Cookies
These cookies are necessary for the Service to function and cannot be disabled. They are typically set in response to actions you take, such as logging in, setting preferences, or filling in forms.
| Cookie | Purpose | Duration |
|---|---|---|
| session_token | Maintains your authenticated session | Session |
| csrf_token | Prevents cross-site request forgery attacks | Session |
| cookie_consent | Stores your cookie consent preference | 1 year |
| next-auth.* | Authentication session management | Session / 30 days |
Analytics Cookies
These cookies help us understand how visitors interact with our website by collecting and reporting information anonymously. Analytics cookies are only set if you consent via our cookie consent banner. We use Vercel Analytics and Google Analytics (via Google Tag Manager) for this purpose.
| Cookie | Purpose | Duration |
|---|---|---|
| _va | Vercel Analytics — anonymous page view tracking | Session |
| _vs | Vercel Speed Insights — anonymous performance metrics | Session |
| _ga | Google Analytics — distinguishes unique users for anonymous traffic analysis | 2 years |
| _ga_* | Google Analytics — maintains session state for a specific property | 2 years |
| _gtm_* | Google Tag Manager — manages and fires analytics tags | Session |
What We Don't Use
Expona does not use marketing cookies, advertising cookies, or third-party tracking pixels. We do not participate in cross-site ad tracking or sell your browsing data to advertisers.
Managing Your Cookie Preferences
When you first visit our website, a cookie consent banner will appear allowing you to choose which types of cookies to accept:
- Accept All: Enables both essential and analytics cookies.
- Essential Only: Only essential cookies required for the Service to function will be used.
You can also control cookies through your browser settings. Most browsers allow you to block or delete cookies. However, blocking essential cookies may prevent the Service from functioning properly.
Changes to This Policy
We may update this Cookie Policy from time to time. Changes will be posted on this page with an updated "Last updated" date. Your continued use of the Service after changes constitutes acceptance of the updated policy.
