This page explains the cookies and browser-storage items Nippy Index uses. Under UK law (the Privacy and Electronic Communications Regulations, PECR), the same rules apply whether information is stored as a cookie or in your browser's local storage. We group ours into essential items that don't need consent, and analytics items that are only used if you accept.
These keep the tool working and remember your own preferences. They stay in your browser only and are never shared. They are not used to track you across other websites.
| Name | Type | Purpose | Lasts |
|---|---|---|---|
| nippyindex_consent | Local storage | Remembers your cookie choice (accept or reject) | Until you clear it or change your choice |
| nippydips_last_location nippydips_last_type | Local storage | Remembers the last location you searched so the tool can pre-fill it next time | Until you clear it |
| (disclaimer acknowledgement) | Local / session storage | Remembers that you've seen the disclaimer so it isn't shown repeatedly | Session or until you clear it |
If you choose "Accept", Google Analytics 4 sets the cookies below to help us understand how the tool is used. They are not set unless and until you accept. If you reject, or ignore the banner, Google Analytics is not loaded and these cookies are never created.
| Name | Provider | Purpose | Lasts |
|---|---|---|---|
| _ga | Google Analytics | Distinguishes one visitor from another | Up to 2 years |
| _ga_G-54Y1XJXPJP | Google Analytics | Keeps analytics session state for this site | Up to 2 years |
You can change your decision at any time using the "Cookie settings" link in the footer on our homepage. You can also delete cookies and local storage at any time through your browser's settings. Blocking analytics does not affect how the tool works.
Loading the page also connects your browser to Google (web fonts) and Cloudflare's cdnjs (charting and sun/moon calculation libraries). These are used to display the page and do not set tracking cookies. More detail is in our Privacy Notice.
NippyIndex describes water conditions only. It is not safety advice and never implies that any location is safe, accessible or suitable for any activity. Always make your own assessment.
