Last updated: March 27, 2026
This Cookie Policy explains what cookies are, how NeutronDB (“we”, “us”, “our”) uses them on neutrondb.com (the “Site”), and the choices you have regarding their use.
What Are Cookies?
Cookies are small text files that a website stores on your browser or device when you visit. They are widely used to make websites function correctly, improve user experience, and provide information to site owners.
Cookies can be:
- Session cookies - deleted automatically when you close your browser
- Persistent cookies - remain on your device for a set period or until you delete them
- First-party cookies - set by the Site you are visiting (neutrondb.com)
- Third-party cookies - set by an external service embedded in the Site (e.g., Google)
Cookies We Use

These cookies are essential for the Site to function and cannot be switched off. They do not store any personally identifiable information.

ndb_currency | Remembers your selected currency preference for calculator displays | Persistent (localStorage) |
Note: ndb_currency is stored in browser localStorage, not as a traditional cookie, but functions similarly as a client-side preference store.
