Cookie Policy
Last Updated: April 29, 2026
What Are Cookies?
Cookies are small text files placed on your device by a website when you visit it. They are widely used to make websites work correctly, remember your preferences, and provide site operators with information about how visitors interact with their pages. Cookies are stored by your browser and sent back to the originating website on subsequent visits.
In addition to cookies, we also use localStorage — a browser feature that stores data locally on your device. Unlike cookies, localStorage data is never automatically transmitted to a server; it stays on your device unless you clear your browser data.
Cookies We Use
We use a minimal set of cookies and local storage, grouped into two categories:
1. Essential Storage
We store your cookie consent preference in localStorage under the key cookie-consent. This allows us to remember whether you have accepted or declined non-essential cookies so we do not show the consent banner on every page visit. This preference is stored only on your device and is never sent to our servers.
This storage is essential to the functioning of the consent mechanism and is set regardless of your cookie preference.
2. Analytics Cookies
If you accept analytics cookies, the following may be set:
- Vercel Analytics — may set anonymous session identifiers to track aggregate page view counts and performance metrics. No personal data is collected. Data is processed by Vercel in accordance with their privacy policy.
- Google Analytics (if enabled) — sets
_gaand_gidcookies to distinguish unique visitors and sessions for traffic analysis. These cookies do not identify you personally. The_gacookie persists for 2 years;_gidpersists for 24 hours.
We do not use advertising, remarketing, or cross-site tracking cookies of any kind.
How to Disable Cookies
You can control and manage cookies through your browser settings. Most browsers allow you to view, block, or delete cookies. Instructions for common browsers:
- Chrome — Settings › Privacy and security › Cookies and other site data
- Firefox — Settings › Privacy & Security › Cookies and Site Data
- Safari — Preferences › Privacy › Manage Website Data
- Edge — Settings › Cookies and site permissions › Manage and delete cookies
Disabling analytics cookies will not affect the functionality of the roof pitch calculator — all calculations run entirely in your browser and do not rely on cookies. Clearing localStorage will reset your cookie consent preference and you will see the consent banner again on your next visit.
Third-Party Cookies
The third-party services that may set cookies on this site are:
- Vercel— our hosting provider. See Vercel's cookie information at vercel.com/legal/privacy-policy.
- Google Analytics(optional) — analytics service by Google LLC. See Google's cookie usage at policies.google.com/technologies/cookies.
We do not allow any other third parties to set cookies through this site.
Cookie Consent
When you first visit roofpitchcalculator.app, a cookie consent banner will appear. You can choose to:
- Accept all cookies — enables both essential storage and analytics cookies.
- Reject non-essential cookies — only the essential consent preference is stored in
localStorage; no analytics cookies will be set.
Your choice is saved in localStorageso you are not prompted again. You can change your preference at any time by clearing your browser's local storage or site data, which will reset the banner on your next visit.
