1. What Are Cookies & Local Storage?
Cookies are small text files placed on your computer or mobile device by
websites that you visit. They are widely used to make websites work
efficiently, provide personalized experiences, and provide operational
reporting to website operators.
In addition to cookies, modern web applications may utilize related
storage technologies such as localStorage and sessionStorage to preserve user preferences (like your dark mode selection or collapsed sidebar
state) locally in your browser.
2. How Evergreen Uses Cookies
Evergreen adopts a privacy-first engineering approach. We do not use marketing cookies, tracking beacons, cross-site profiling
trackers, or invasive social media widgets on our marketing landing pages or application dashboards.
We utilize cookies and storage technologies strictly to:
- Authenticate you and keep your dashboard session securely active;
-
Prevent Cross-Site Request Forgery (CSRF) and secure API endpoints;
-
Remember client-side UI preferences (such as selected timeframe ranges
on latency graphs);
-
Balance server load and route traffic efficiently across edge regions.
3. Categories of Cookies We Use
| Name / Key | Type | Purpose | Duration |
__Host-evg_session | Strictly Necessary | Cryptographically signed token used to authenticate your user
session and workspace permissions. | Session / 30 days |
evg_csrf_token | Strictly Necessary | Protects forms and API mutations against cross-site request
forgery attacks. | Session |
__cf_bm / Cloudflare | Strictly Necessary | Placed by Cloudflare to manage inbound traffic, detect malicious
bot networks, and defend against DDoS attacks. | 30 minutes |
evg_theme_preference | Functionality / LocalStorage | Remembers UI theme preference (Dark mode default) and interface
collapse state. | Persistent |
4. Third-Party Technologies
Our authentication and infrastructure providers may set temporary cookies
during specific interactions:
- Cloudflare: Provides edge reverse-proxy caching, SSL termination,
and DDoS protection. Cloudflare cookies are strictly necessary for edge security
and performance.
- Stripe (Customer Billing Portal): When navigating to update
credit cards or view receipts, Stripe may set fraud detection cookies (such
as
__stripe_mid) strictly for risk prevention and
compliance with banking standards.
5. Managing Your Preferences
Because our cookies are strictly necessary for the fundamental operation
and security of the Service, disabling them may prevent you from
authenticating or using your Evergreen dashboard.
However, you can configure your browser to block or delete cookies at any
time:
- Chrome: Settings → Privacy and security → Cookies
and other site data;
- Firefox: Settings → Privacy & Security → Cookies
and Site Data;
- Safari: Preferences → Privacy → Manage Website
Data;
- Brave / Edge: Settings → Site Permissions → Cookies
and stored data.
6. Updates to This Policy
We may update this Cookie Policy from time to time to reflect changes in
legal requirements or our operational practices. Any updates will be
posted on this page with an updated "Last updated" date at the top of the
page.
