Cookies, browser storage and push.
In effect from 20 July 2026. Read together with the privacy notice.
This site carries no advertising, no analytics and no tracking pixels. It does, however, load a notification service on every page, and that service writes to your browser. Here is exactly what happens.
What feldspire itself stores
Nothing. The pages are static HTML, CSS and a small amount of our own JavaScript, and none of it sets a cookie or writes to storage.
What OneSignal stores
The OneSignal software development kit is loaded from its content delivery network on every page of this site, including this one, so that the subscribe button can work when you reach it. On load it may write the following to your browser:
- Service worker
- A background script registered at /OneSignalSDKWorker.js. It is what allows a notification to be delivered when this site is not open in a tab. It cannot read your other tabs or your files.
- Local storage and IndexedDB entries
- Identifiers that let OneSignal recognise this browser as the same subscriber over time, plus the state of your subscription and basic configuration.
- Push subscription record (only if you allow notifications)
- The push endpoint issued by your browser vendor and the keys needed to encrypt messages to it, held on OneSignal's servers in the United States.
- Subscriber tags (only if you use the form)
- Your email address, the site domain, the name you entered, and a note that the subscription came from a web form.
OneSignal, Inc. is a United States company acting as our service provider. Its privacy policy is at onesignal.com/privacy_policy, and the cross-border transfer is explained in our privacy notice.
Fonts
Typefaces are loaded from Google Fonts, which means your browser makes a request to a Google server and that server sees your IP address as part of any ordinary web request. No cookie is set by us for this purpose.
Who decides about notifications
Your browser does, not us. We can ask; only you can grant. If you decline, or ignore the prompt, nothing on this site stops working and nothing is hidden from you. If you accept and later change your mind, revoke the permission for feldspire.com in your browser settings and delivery stops immediately.
How to remove all of it
- Chrome and Edge: Settings, Privacy and security, Third-party cookies and site data, See all site data, search for feldspire.com, delete. Notification permission lives under Site settings, Notifications.
- Firefox: Settings, Privacy and Security, Cookies and Site Data, Manage Data, search for feldspire.com, remove. Notifications are under Permissions on the same page.
- Safari: Settings, Privacy, Manage Website Data, search, remove. Notifications are under Settings, Websites, Notifications.
Clearing site data also unregisters the service worker. If you want the subscription record deleted at OneSignal's end as well, ask us at [email protected] and we will do it.
Links to the stores
Buttons on the builds go to official Google Play and App Store listings. Once you leave this site, whatever Google or Apple stores in your browser is governed by their policies, not ours. Our links carry no affiliate tags or referral codes, which is stated on the front page under What pays for this.
