313 Audio

Ear Training privacy

Last updated 11 October 2026

This page covers the Ear Training app for iPhone and its page at oscarkiki.com/apps/ear-training. 313 Audio is a brand of Oscar Kiki ("we", "us").

The app

The app collects no personal data. It has no accounts, no ads, no analytics and no tracking, and it doesn't send anything to us. Anything it saves, such as your settings, stays on your phone.

Sound

The app plays sounds that it makes on your phone. It never uses your microphone and records nothing.

Your scores

Your answers, accuracy, streak and drill settings are saved on your phone only, inside the app. Deleting the app deletes them.

Buying the unlock

If you buy the one-time unlock, the purchase is handled entirely by Apple under its own terms and privacy policy. We never see your payment details. The app only asks the App Store whether the unlock has been bought on your Apple ID, so it can turn the full app on and restore it on a new phone.

The website

The Ear Training page runs on oscarkiki.com, which is hosted by HubSpot and uses cookies, analytics and the Reddit Pixel as described in the Oscar Kiki privacy policy. If you give us your email address on that page, to hear when the app launches or to send us a question, we store it in HubSpot with your message and use it only for that and occasional news about our apps. Every email has a one-click unsubscribe link.

Children

The app collects no personal data from anyone, including children.

Contact

Questions about privacy or the app: use the form at the bottom of the Ear Training page and we'll reply by email.

Changes

If we change how the app handles data, we'll update this page and the date above before the change ships.
