Cookies & storage

Updated: 18 August 2026 · Applies to plumetrack.com

Most sites publish a long list of trackers. This one has almost nothing to list, so here is the complete picture of what plumetrack.com puts in your browser and when.

The short version

Until you press Accept in the band at the bottom of the page, this site stores nothing beyond what your browser caches by itself, and no notification code is downloaded at all. There are no advertising trackers and no third-party analytics anywhere on the site.

Strictly necessary storage

userConsent

A single entry in your browser's local storage that records whether you accepted or declined. It holds one short word, is read only by this site, and exists so the band does not reappear on every page. It stays until you clear site data. Without it the site still works, but you would be asked again on every visit.

Notifications and e-mail updates

These load only after you accept, either by pressing Accept in the band or by ticking the consent box in the subscription form.

OneSignal web SDK. Once consent is given, the script is fetched from the OneSignal content delivery network and creates its own keys in local storage together with a database named ONE_SIGNAL_SDK_DB in IndexedDB. These hold the subscription identifier for this browser and the settings needed to deliver a notification.
Service worker. A file named OneSignalSDKWorker.js is registered so that notifications can be delivered while the tab is closed. It is registered only after consent.
Purpose and duration. The keys stay until you revoke notification permission for this site, press Decline, or clear site data in your browser.

Analytics and advertising

None. There is no analytics tag, no advertising pixel, no social network button and no remarketing code on any page of this site. If that ever changes, this section will list the tool before it is switched on.

Fonts

The page requests the Space Mono typeface from Google Fonts. That request reaches Google's servers and, like any web request, carries your IP address and browser string. No cookie is set by us in that process.

What Accept and Decline actually do

Accept writes the userConsent entry, then loads the OneSignal script and lets your browser ask whether you want notifications. You can still say no at the browser prompt.
Decline removes the keys this site may have created — anything beginning with os_, anything containing onesignal, the userConsent entry itself — deletes the ONE_SIGNAL_SDK_DB database, and then records the refusal so you are not asked again. The notification script is never downloaded.

Changing your mind

Clear site data for plumetrack.com in your browser settings and the band will appear again on your next visit, letting you choose differently. Notification permission itself is controlled in your browser, under site settings for this address, and can be revoked there at any time without telling us.
