1. What are cookies?

Cookies are small text files stored on your device when you visit a website. We also use similar technologies (e.g. local storage, session tokens) for authentication and preferences.

2. Cookies we use

2.1 Essential (strictly necessary)

Supabase authentication cookies — keep you signed in securely
Session / CSRF protection — help prevent unauthorized requests
Stripe — may set cookies during checkout on Stripe-hosted pages

These are required for login, billing, and core security. Disabling them may prevent you from using the Service.

2.2 Functional

Theme or UI preferences (e.g. light/dark mode) where stored locally
Chrome extension sync storage for extension sign-in state

2.3 Analytics (optional)

When you click "Accept All" in our cookie banner:

PostHog — product analytics (events, feature usage)
Google Analytics (GA4) — aggregated website traffic and usage metrics
Vercel Analytics / Speed Insights — aggregated page performance metrics (loaded on all visits; privacy-preserving, no advertising)

Analytics tools are used for product improvement and performance measurement, not advertising retargeting. You may contact privacy@trackmyopt.com to request opt-out, or choose "Essential Only" in the cookie banner.

2.4 Advertising cookies

When you click "Accept All" in our cookie banner, we load Google AdSense to display ads that help support free educational content. AdSense may set cookies for ad delivery and measurement. We do not use Facebook Pixel, Google Ads remarketing, or similar ad-tracking beyond AdSense.

3. Third-party cookies

Third parties (Supabase, Stripe, Google sign-in, analytics providers) may set their own cookies when you use those features. Their policies govern those cookies.

4. How to manage cookies

Browser settings: Chrome, Safari, Firefox, and Edge let you block or delete cookies
Sign out: Clears session cookies for your account
Analytics: If we offer an in-app analytics opt-out, use Settings → Privacy; otherwise contact privacy@trackmyopt.com

Blocking essential cookies will break login and dashboard access.

5. Do Not Track

Some browsers send "Do Not Track" signals. We do not currently respond differently to DNT signals because there is no industry standard; we limit tracking to the categories above.

6. Updates

We may update this Cookie Policy. See the version date at the top of this page.
