Cookie Policy

Last updated: July 1, 2026

This policy describes how the Sentinel Core Vision website (the "Site"), operated by Sentinel Core Vision, a sole proprietorship, uses cookies and similar browser-storage technologies. "Cookies" here is used broadly to include cookies, local storage, and comparable mechanisms a browser provides.

What cookies and storage are

A cookie is a small text file a website or a service it relies on can store in your browser. Local storage is a related browser feature that lets a site keep small amounts of data on your device between visits. Both let a site recognise your session and remember essential state, such as whether you are signed in.

Our approach

We aim to keep browser storage to a minimum. The Site uses strictly-necessary items only — the things required for core functions like signing in, completing a purchase, and keeping the Site secure. We do not use advertising cookies, and we do not use cross-site tracking cookies or third-party advertising networks to build a profile of you across other websites.

What we use, and why

The essential items fall into a small number of categories:

• Authentication session. When you sign in, our authentication provider (Supabase) sets and reads session data so you stay signed in as you move between pages and can access your account. Without this, sign-in cannot work.
• Checkout and payment session. When you start a purchase, our payment processor (Stripe) sets and reads the data it needs to present a secure checkout, process the transaction, and guard against fraud. Without this, checkout cannot complete.
• Hosting and security. Our hosting and content-delivery provider (Cloudflare) may set standard items used to route traffic, keep the connection secure, and protect the Site against abuse and automated attacks.
• Web fonts. The Site loads fonts from Google Fonts so pages display consistently. Loading a font from a third party involves a request to that provider; see their policy linked below.

Browser local storage and your sign-in

When you are signed in, your browser's local storage may hold your authentication session — for example, the token that keeps you signed in — so you don't have to re-enter your credentials on every page. This data stays in your browser on your device. Signing out, or clearing your browser's site data, removes it.

Advertising and cross-site tracking

To be clear: the Site does not set advertising cookies and does not use cross-site tracking cookies. We do not sell or share this browser data with advertisers.

Controlling cookies and storage

You are in control of what your browser stores. Most browsers let you:

• view and delete cookies and site data for individual sites;
• block or limit cookies and storage, either broadly or per site; and
• clear all browsing data, including local storage, at any time.

These controls live in your browser's privacy or site-settings menu, and the exact steps vary by browser and version. Your browser's own help pages describe how to manage them.

Please note: the items described above are essential to how the Site works. If you block or delete them, some features may stop functioning — in particular, signing in and completing checkout may break — and you may be signed out. Blocking essential storage does not disable a tracking feature here, because we do not use one; it simply removes what the Site needs to operate.

Third-party services

Some essential items are set by trusted service providers we rely on to run the Site. Each operates under its own terms and privacy practices, and you can review their policies directly:

• Stripe — payment processing and checkout. See Stripe's privacy policy and cookie policy.
• Supabase — authentication and accounts. See Supabase's privacy policy.
• Cloudflare — hosting, content delivery, and security. See Cloudflare's privacy policy and cookie policy.
• Google Fonts — web font delivery. See Google's privacy policy.

We are not responsible for the content of third-party policies, and those providers may update their practices over time. Links are provided for your convenience.

How this policy relates to privacy

For a fuller picture of what personal information we collect, how we use it, and the choices you have, please read our Privacy Policy. Your use of the Site and our services is also governed by our Terms of Service.

Changes to this policy

We may update this policy from time to time — for example, if we add or remove a service provider. When we make changes, we will update the date at the top of this page. Please check back periodically.
