Cookie Policy | Standard Tonnage

1. About this policy

This Cookie Policy explains how Standard Tonnage Limited uses cookies and similar technologies on standardtonnage.com and on our application at app.standardtonnage.com. It should be read alongside our Privacy Policy.

2. What cookies are

Cookies are small text files placed on your device by a website. “Similar technologies” include local storage, session storage, and pixel tags. In this policy, “cookie” refers to all of these.

3. Our approach: minimal and necessary

We do not use advertising cookies, third-party tracking cookies, or cross-site tracking. We use only cookies that are strictly necessary to deliver the service you have requested (for example, keeping you logged in securely). Our website analytics (Vercel Analytics) is designed to operate without cookies or persistent identifiers.

Because we currently set only strictly necessary cookies, we do not display a cookie consent banner. Under regulation 6(4) of the Privacy and Electronic Communications Regulations 2003 (PECR), consent is not required for strictly necessary storage. If we ever introduce cookies that are not strictly necessary, we will ask for your consent before they are set and update this policy accordingly.

4. Cookies we currently set

Name	Set by	Purpose	Category	Lifetime
sb-*-auth-token	Supabase (app.standardtonnage.com)	Keeps you securely signed in to your account.	Strictly necessary	Session / up to 7 days
sb-refresh-token	Supabase (app.standardtonnage.com)	Refreshes your session without requiring you to re-enter your password unnecessarily.	Strictly necessary	Up to 30 days
next-*	Next.js framework (both domains)	Internal state needed to render the correct page content.	Strictly necessary	Session
__Host-csrf	Standard Tonnage	Protects against cross-site request forgery on authenticated actions.	Strictly necessary	Session

Cookie names shown with * may vary by version. The categories and purposes do not change.

5. Local and session storage

Local storage: we may cache a small amount of application data in your browser (for example, dashboard preferences or last-viewed filters) to make the application responsive. None of this data is used for tracking and none of it leaves your browser without your action.
Session storage: used for temporary, in-tab state that is discarded when you close the tab.

6. Analytics

We use Vercel Analytics to understand aggregate usage of our marketing site (for example, how many people visit the homepage in a given week). Vercel Analytics is designed to operate without cookies, without persistent identifiers, and without cross-site tracking. Individual visitors are not identified.

7. How to control cookies

Because we only set strictly necessary cookies, there is nothing to opt out of on our side. You can at any time clear cookies for our domains from your browser settings. Doing so will sign you out of the application; you will need to sign in again.

If you wish to block cookies entirely in your browser, the Service will not function correctly (you will be unable to stay signed in). Guidance for controlling cookies in major browsers is published by the ICO at ico.org.uk/your-data-matters/online/cookies.

8. Do Not Track

Our marketing site respects the “Global Privacy Control” signal where present. Because we do not use tracking cookies, no additional action is required.

9. Changes

We will update this Cookie Policy if our practice changes. If we introduce cookies that are not strictly necessary, we will present a consent banner and will not set such cookies until you have given consent. Material changes are highlighted at the top of this page for at least 30 days.
