Cookies & local storage
The calculator uses only the browser storage and third-party checkout technology needed to make the service work. There are currently no advertising cookies or behavioural tracking cookies on the site.
Calculator project storage
The site uses browser local storage to keep your current calculator project during the checkout flow. This allows your selections to survive a redirect to Stripe and lets the calculator restore them if checkout is cancelled.
This storage is functional rather than advertising-related. You can remove it using your browser's site-data or privacy controls.
Stripe Checkout
When you choose to pay, you are redirected to Stripe Checkout. Stripe may use cookies or similar technologies that are necessary for payment processing, fraud prevention, security and operation of its checkout service. Stripe controls those technologies on its own service.
Cloudflare
Cloudflare provides hosting, network delivery and security for the website. Cloudflare may use technical identifiers or security-related technologies that are necessary to deliver and protect the service.
Future changes
If Window Price Calculator later adds optional analytics, advertising or other non-essential tracking, the site will update this notice and introduce consent controls where required before those technologies are used.
