Cookie Policy

Effective 2026-04-19

This Cookie Policy explains what cookies and similar technologies we use on https://www.corpstacking.com and why. It supplements our Privacy Policy.

What is a cookie?

A cookie is a small text file a website stores on your device to remember things between page loads or visits — like whether you’re signed in. We also use a few similar technologies: localStorage, sessionStorage, and the browser’s Push API subscription record.

Categories we use

Strictly necessary

Required for the site to function. These cannot be disabled and do not require consent.

  • Supabase auth cookies (sb-…-auth-token) — keeps you signed in.
  • Session flags (pwa_installed) — lets the server render the right “install the app” messaging.
  • Stripe cookies set on the checkout and billing-portal pages — required for fraud prevention and 3-D Secure.

Preferences

Remember your choices. You can clear these from your browser anytime.

  • splash_shown (sessionStorage) — ensures the PWA splash shows once per session, not on every page change.
  • pwa-banner-snooze-until (localStorage) — remembers that you dismissed the “install the app” banner for seven days.

Analytics

  • Vercel Analytics + Speed Insights — privacy-friendly, cookie-less aggregate analytics. Counts visits and measures page performance without tracking individuals.
  • PostHog (optional, only if you consent) — product analytics to help us understand which features are used. Stores a random anonymous ID.

Advertising

Free-tier users see ads via Coinzilla. Pro and Pro+ users never see ads and do not have ad cookies set.

  • Coinzilla — ad-serving and basic frequency capping. This only loads for free-tier visitors who have accepted cookies.

How to control cookies

  • When you first visit the site you can accept or reject non-essential cookies via the cookie banner. Your choice is stored in localStorage as cookie_consent.
  • To change your choice, clear that key from your browser’s localStorage and reload — the banner will reappear.
  • Most browsers let you block or delete cookies from their settings. Blocking the strictly-necessary cookies will log you out.
  • Do Not Track: we honor the Global Privacy Control (GPC) signal as an opt-out for optional cookies.
