GradeThread

Cookie Policy

Effective date: April 1, 2026

This Cookie Policy explains how Pearson Media LLC (“GradeThread,” “we,” “us,” or “our”) uses cookies and similar technologies on gradethread.com and within the FlipDesk workspace. It supplements our Privacy Policy.

1. What are cookies?

Cookies are small text files stored on your device by your browser when you visit a website. They let the site remember information about your visit. We also use similar technologies such as local storage, session storage, pixels, and SDKs, which we refer to collectively as “cookies” in this policy.

2. Cookies we use

2.1 Strictly necessary

Required to operate the Service, sign you in, keep you signed in, maintain session state, and protect against fraud and abuse. The Service will not function correctly without these.

  • Supabase auth tokens — authentication and session continuity (stored in local storage with PKCE).
  • Cloudflare — bot mitigation, DDoS protection, and edge routing.
  • CSRF and security tokens — protect against cross-site request forgery on form submissions.
  • UI preferences — theme, sidebar state, and onboarding progress.

2.2 Analytics and performance

Help us understand how visitors and signed-in users interact with the Service so we can improve it.

  • PostHog — product analytics (pageviews, feature usage, funnels). PostHog cookies and IDs typically expire within 12 months.

2.3 Diagnostics and error monitoring

  • Sentry — captures crashes, stack traces, and performance traces so we can debug issues. Sentry uses session identifiers but does not place advertising cookies.

2.4 Payment processing

  • Stripe — required for checkout, subscription management, fraud prevention, and PCI compliance on billing pages.

2.5 Advertising

We do not currently use third-party advertising cookies or sell personal information for advertising purposes. If that changes, we will update this policy and provide an opt-out where required.

3. How long do cookies stay?

Session cookies expire when you close your browser. Persistent cookies remain until they expire or you delete them. The retention of each cookie depends on its purpose; for example, auth tokens are refreshed regularly, while UI preferences may persist for up to a year.

4. Your choices

  • Browser controls. Most browsers let you block or delete cookies through their settings. Blocking strictly necessary cookies will break sign-in and other core features.
  • Do Not Track. Because no common industry standard exists for honoring DNT signals, we do not respond to them. We do, however, honor Global Privacy Control (GPC) signals where required by law.
  • Analytics opt-out. You can disable product analytics from your account preferences in Settings where available.
  • Mobile devices. You can reset advertising identifiers and limit ad tracking in your device settings.

5. Changes to this policy

We may update this Cookie Policy from time to time. When we do, we will revise the “Effective date” above and, where required, provide additional notice.
