How evidencefund.com uses cookies
When you browse evidencefund.com, small data files called cookies may be stored on your device. These files help websites function properly and provide insights to website owners about how their sites are being used. Below, we explain which cookies evidencefund.com uses and their purposes.
Strictly necessary cookies
These cookies are essential for the website to function correctly. They do not require your consent and cannot be disabled through our cookie settings.
| Name | Owner | Purpose | Expires |

NEXT_LOCALE | evidencefund.com / Next.js | Stores your language preference for localised routing, ensuring you see content in your chosen language. | Browser session |
__cf_bm | Cloudflare | Used by Cloudflare for bot management and abuse detection to protect evidencefund.com from automated threats. | Short-lived (Cloudflare-managed) |

What data is contained in the PostHog cookie?
The PostHog cookie saves the following details in a structured format:
- $device_id: A unique random code (UUID) assigned to your device
- distinct_id: An anonymous identifier for tracking purposes. Initially identical to your device ID, but may link to your account if you log in
- $sesid: Details about your current browsing session, including when it started, a unique session identifier, and recent activity timestamps
- $epp: Technical flags used by PostHog for internal features
- $initial_person_info: Records showing how you arrived at our site (such as from a search engine or direct visit) and which page you landed on first
This cookie contains no information that can identify you personally, such as your name, email, or other private details.
Local storage (analytics, optional)
In addition to cookies, our analytics tools use your browser's local storage after consent is granted. This data stays on your device and is not transmitted separately to our servers.
