Privacy Policy
Data Collection
Our website and mobile apps collect minimal data. Anonymous usage analytics (page views, calculator interactions, store link clicks) are handled entirely by PostHog — we do not store any analytics data ourselves. If you provide your email address via a signup form on the website or in one of our apps, it is held by Buttondown, our newsletter provider — we do not store your email ourselves. You can unsubscribe at any time.
How We Use Your Data
Analytics data is used solely to improve our tools. Email addresses are used only for product update notifications. We do not sell or share personal data with third parties for marketing purposes.
Third-Party Services
The website is hosted on Vercel. Anonymous analytics are managed by PostHog (EU-hosted, eu.i.posthog.com). Email subscriptions are managed by Buttondown. All user data is held by these third-party providers — we do not operate our own data stores. No advertising or tracking scripts are loaded.
Cookies
The website does not set any cookies. Analytics use in-memory storage only and do not persist across sessions. Our mobile apps use in-memory analytics only. No advertising or tracking cookies are set on any platform.
Your Rights
We do not hold personal data directly. If you subscribed to our newsletter, you can unsubscribe via the link in any newsletter email. Analytics are anonymous and do not persist across sessions, so there is no personal data to access or delete.
