Cookie policy
Last updated : April 19, 2026
We use the minimum number of cookies possible, all essential for Service operation. No advertising tracking, no third-party marketing cookies, no profiling. Here's the complete list.
What is a cookie?
A cookie is a small text file stored on your browser when you visit a site. It allows the site to recognize you or remember information. Some cookies are strictly necessary (without them, the site doesn't work), others are optional (analytics, advertising, etc.).
Cookies we use
| Name | Issuer | Purpose | Duration |
|---|---|---|---|
sb-access-token | Supabase | Maintain your login session on app.hellomarkus.ai | 7 days |
sb-refresh-token | Supabase | Renew your session without re-logging in | 30 days |
__stripe_sid, __stripe_mid | Stripe | Secure payment transactions (anti-fraud) | Session / 1 year |
Strictly necessary (no consent required)
Analytics (opt-in, disabled by default)
Currently, no third-party analytics cookies are set. If we add an audience analysis tool in the future (e.g., Plausible, Simple Analytics, or Google Analytics), we'll display a GDPR-compliant consent banner and you'll be able to refuse.
Marketing (never)
No advertising, retargeting, or cross-site tracking cookies are set by HelloMarkus. No Facebook Pixel, no Google Ads remarketing, no LinkedIn Insight tag. Period.
Third-party cookies beyond Stripe
External features may set cookies:
- Google Fonts — font loading (no identifying cookies, just CDN requests)
- LinkedIn — if you log in via LinkedIn OAuth, their technical cookies apply
