Privacy Policy

Last updated: February 17, 2026

Who we are

WonderTwin is operated by Saltwyk ("we", "us", "our"). This privacy policy explains how we collect, use, and protect information when you visit our marketing site at wondertwin.ai.

What we collect

Analytics data (with your consent)

We use PostHog for website analytics. PostHog is only activated if you click "Accept" on the cookie consent banner. Until you consent, no analytics data is collected.

When you consent, PostHog may collect:

  • Pages visited and time spent on each page
  • Referral source (how you found us)
  • Browser type, operating system, and screen size
  • Country and general region (not precise location)
  • Interactions with page elements (clicks, scrolls)

PostHog stores this data on servers in the United States. You can review PostHog's privacy policy for details on their data handling practices.

Early access form

If you submit the early access form, we collect the information you provide: your email address, the services you integrate with, your integration count, and your pain points. This data is stored in a Cloudflare D1 database and used solely to contact you about WonderTwin early access.

How we use your data

  • Analytics data helps us understand how visitors use the site so we can improve it.
  • Early access submissions are used to contact you about WonderTwin and to understand what twins to prioritize.

We do not sell, rent, or share your personal data with third parties for marketing purposes.

Cookies and local storage

We use browser localStorage (not cookies) to remember:

  • Your analytics consent preference (wt-analytics-consent)
  • Your dark mode preference (wt-dark-mode)
  • Whether you dismissed the top banner (wt-banner-dismissed)

PostHog uses localStorage for session tracking when you have consented to analytics. No tracking cookies are set before consent.

Your choices

  • Decline analytics: Click "Decline" on the cookie consent banner. No analytics data will be collected.
  • Revoke consent: Clear your browser's localStorage for this site. The consent banner will reappear on your next visit.
  • Request data deletion: Contact us at the email below and we will delete any data associated with you.

Data retention

Analytics data is retained according to PostHog's default retention settings. Early access form submissions are retained until the early access period ends or until you request deletion.

Children's privacy

WonderTwin is a developer tool. We do not knowingly collect data from children under 16. If you believe a child has submitted data to us, please contact us and we will delete it.

Changes to this policy

We may update this policy from time to time. Changes will be reflected by the "Last updated" date at the top of this page.
