Draft. Last updated 13 November 2026.
Notched is built to know as little about you as possible.
The app
- Your audio stays on your Mac. Notched filters sound in real time and plays it straight back. It does not record, store or send audio anywhere.
- No account. The app has no sign-in.
- No analytics, no ads, no trackers. The app does not report how you use it.
- Your settings stay local. Your pitch, mixes, goals and daily listening minutes are saved in the app's preferences on your Mac. Deleting the app's preferences removes them.
This website
This site sets no cookies and runs no analytics or advertising scripts. The sound demo runs entirely in your browser. Our hosting provider keeps standard server logs, such as IP address and requested page, for security and reliability.
When you buy
Payments are handled by Polar Software, Inc., our Merchant of Record, and its payment processor Stripe. They collect your email address, billing country or address, and payment details to complete the sale, deliver your download, and meet tax and legal duties. We never see your full card number.
From Polar we receive your name, email address, country and order details. We use them only to deliver the app, answer support requests, handle refunds and keep required business records.
When you email us
We keep your message and address for as long as needed to help you.
Your choices
You can ask what we hold about you, or ask us to delete it, by writing to support. Order records that tax law requires us to keep are held by Polar.
Changes
If this policy changes, the new version will be posted here with a new date.
