What a cookie is

A cookie is a small text file your browser saves on your device so a website can remember something between visits. The Hydroline website uses one cookie and uses it as sparingly as we can.

The cookie we set

hl_cookie_pref — first-party. Records whether you accepted or rejected the cookie banner. Expires after 12 months. Without it we would have to show you the banner on every page load. No personal data is stored inside the cookie value; it is either “accept” or “reject”.

What we deliberately don’t do

No third-party advertising cookies (no Facebook Pixel, no Google Ads conversion tag).
No cross-site tracking pixels.
No analytics that fingerprint your browser.
No session-replay tools that record your mouse movements.

Fonts

The website loads typography from Google Fonts. Google publishes its own statement about what it logs at the moment a font file is requested. We have configured the site to use the standard subset, no behavioural tracking parameters added.

Changing your mind

The small cog icon at the bottom-left of every page lets you reopen the cookie banner and change your preference at any time. You can also clear cookies from your browser settings to reset the choice entirely.

Browser-level cookie controls

Every major browser lets you block or wipe cookies. Search your browser’s help for “manage cookies” if you are not sure how. If you block our single cookie, the only effect is that the banner will show again next visit.
