Privacy Policy

Last updated: March 27, 2026

What we collect

When you join the waitlist, we collect your email address. That's it. No tracking cookies, no analytics, no device fingerprinting.

Why we collect it

• To let you know when Quack Stack is ready for early access
• To send occasional product updates about Quack Stack

Who has access

Your email is processed by our email service provider (US-based, with appropriate data transfer safeguards). The website is hosted in the EU. We do not sell, rent, or share your personal data with anyone else.

How long we keep it

We keep your email until you ask us to delete it, or until the waitlist closes - whichever comes first. You can unsubscribe at any time from any email we send.

Your rights

Under GDPR and similar regulations, you can:

• Access - ask what data we hold about you
• Delete - request complete removal
• Portability - get your data in a standard format
• Withdraw consent - unsubscribe at any time

Email privacy@quack-stack.com for any of these. We'll respond within 30 days.

Legal basis

We process your data based on your consent (GDPR Article 6(1)(a)), given when you submit the waitlist form.
