Analytics
This website uses privacy-friendly, cookieless analytics (provided by PostHog) to understand aggregate site traffic: which pages are visited, roughly where visitors come from (referrer and country), and which links are clicked. No analytics cookies or other identifiers are stored on your device, and this data is not used to identify you.
Cookies
This website itself does not set cookies. Embedded third-party content – such as the Spotify player on the Soundscapes page – may set its own cookies, governed by the respective provider’s privacy policy.
Newsletter
If you sign up for product updates, your email address is stored with Resend, our email delivery provider, and used only to send you the updates you asked for. Every email contains an unsubscribe link, and unsubscribing takes effect immediately.
Contact form
When you contact us, the details you submit (name, email address, and your message) are sent to us by email and used solely to respond to your inquiry. They are not added to any marketing list unless you explicitly opt in.
Donations
Donations are processed by Stripe. We never see or store your payment card details; Stripe’s handling of your data is governed by Stripe’s privacy policy.
Hosting
This website is hosted on Vercel, which processes standard technical request data (such as IP addresses) as necessary to serve the site securely.
