What we collect

When you buy still.synth for Mac or Windows on this website, our payment processor (Stripe) collects your payment details and billing information directly — we never see or store your card number. We receive your email address in order to deliver your license key and provide support.

How we use it

Your email is used only to send your license key, purchase receipt, and — if you ask for it — support. We don't sell or share your email with third parties, and we don't send marketing email unless you separately opt in.

The software itself

still.synth does not track your usage or transmit any of your musical data. The Mac and Windows versions make only two kinds of network requests: license activation, which sends your license key and an anonymous ID of your computer so the key can be tied to it, and an update check about once a week, which only asks our server for the latest version number and sends nothing about you.

The iPhone app

still.synth for iPhone collects no data. It has no accounts, no analytics and no tracking, and it makes no network requests. Purchases go through Apple's App Store, so we never receive your payment details or your Apple ID. Bluetooth is used only to connect MIDI devices or your computer when you turn it on. Your recordings and exports stay on your phone unless you share them yourself.

Third parties we use

Stripe (payments), Resend (transactional email), and Cloudflare (hosting and license infrastructure). Each processes data only as needed to provide their service to us.

This website uses the Meta pixel to measure our ads: when you visit, Meta may receive which pages you viewed and whether you started or completed a purchase, along with standard browser data. You can opt out of ad personalization in your Meta account settings or block it with any tracker blocker.
