Privacy Policy

Simple Tuner with No Ads does not collect or transmit any data, including personal information. Sound from the microphone never leaves your iPhone.

What the app handles

• Microphone. With your permission, the app uses the microphone only while it is open on screen and its microphone button is on, to measure the pitch of the note you play. You can switch the microphone off at any time with that button. The sound is analyzed on your iPhone as it arrives and then discarded. It is never recorded, saved to a file or sent anywhere, to the developer or anyone else.
• The app never connects to the internet on its own. Only when you tap the ⓘ at the top left does it open the support page, in Safari inside the app. Safari loads the page, and the app sends nothing to the developer. How this website handles access is described under “This website” below.
• It contains no ads, analytics, tracking or third-party SDKs, and there is no account.
• It stores your concert pitch setting (for example 442 Hz) on your iPhone, so it is there the next time you open the app. This is never sent off the device.
• It has no features that use the camera, photos, contacts or location.

Deletion

Deleting the app also deletes everything it stored on your device. The developer never receives any of it, so there is no data on the developer's side to delete.

Diagnostics

The app has no crash reporting or usage reporting of its own. If you have chosen in your iPhone's settings to share analytics with Apple, Apple handles diagnostic information, and the developer may see crash reports through Apple's standard tools.

Support emails

If you email support, your email address, your message and any attachments are used only to answer your question and look into the problem. Support emails are received and stored with Proton Mail, provided by Proton AG, and are deleted six months after your request has been resolved. To have them deleted sooner, contact us at the address below.
