Privacy Policy

1Permissions We Request

Fretkit requests a single optional permission, and only at the moment you first use the feature that needs it:

• Microphone — used solely by the tuner to detect the pitch of the string you play. You are asked for permission the first time you open the tuner, not when you launch the app. If you decline, every other part of Fretkit continues to work normally; only live pitch detection is unavailable.

Fretkit does not request access to your contacts, photos, location, calendars, health data, or any other personal information. You can review or revoke the microphone permission at any time in your device's Settings.

2Information We Collect

Fretkit is designed to collect as little as possible. In practice that means it collects no personal information at all.

Microphone audio (tuner)

When the tuner is active, sound from the microphone is processed in real time on your device to estimate the pitch you are playing. This audio is never written to disk, never recorded, and never sent off the device or to us. When you leave the tuner, processing stops.

App preferences

Fretkit stores your choices — such as your selected instrument, tuning, color scheme, fretboard finish, reference pitch, and last-viewed key — on your device so the app remembers them between sessions. This information stays local to your device and is not personal data about you.

Purchases

If you buy Fretkit Pro, the purchase is handled entirely by Apple through the App Store. Fretkit receives only an anonymous confirmation of whether you own the upgrade; it never sees your name, payment card, or Apple Account details.

3How We Use Your Information

Because Fretkit collects no personal data, there is very little to use. The limited information described above is used only to make the app work:

• Microphone audio is used to power the live tuner while it is on screen.
• Your saved preferences are used to restore the app to the way you left it.
• Your Pro entitlement is used to unlock premium features you have purchased.

We do not use any of this information for profiling, advertising, or analytics.

4Third-Party Services

Fretkit does not embed advertising SDKs, analytics SDKs, or social-media trackers. The only third party involved is Apple:

• Apple App Store & StoreKit — processes purchases of Fretkit Pro and manages restoring previous purchases. Apple's handling of that transaction is governed by Apple's Privacy Policy.

Fretkit does not send your data to any other external service. Scale, chord, and tuning data is bundled inside the app, so the app works fully offline.

5Data Storage & Security

Your preferences are stored locally on your device using Apple's standard app-storage mechanisms. Because nothing is uploaded to a Fretkit server — there isn't one — there is no remote database of your information to be breached, leaked, or subpoenaed.

Tuner audio exists only transiently in memory while the tuner is open and is discarded immediately; it is never persisted.

6Data Sharing

We do not sell, trade, rent, or otherwise transfer any information to third parties. There is no personal data to share, and we have no interest in collecting any. We would only disclose information if required to do so by law — and in practice we hold nothing about you that could be disclosed.

7Data Retention & Deletion

You are always in control of the small amount of data Fretkit keeps:

• Resetting preferences from within the app's Settings returns Fretkit to its defaults.
• Deleting Fretkit from your device removes all of its locally stored settings.
• Microphone audio is not retained at all, so there is nothing to delete.

8Tracking & Advertising

Fretkit does not track you. There are no advertising networks, no cross-app or cross-site tracking, and no third-party analytics. Fretkit does not use Apple's App Tracking Transparency prompt because it performs no tracking that would require one. There are no ads anywhere in the app — including, deliberately, the tuner.

9Children's Privacy

Fretkit is a general-audience music utility and is not directed at children under 13. We do not knowingly collect personal information from anyone, including children. Because the app collects no personal data, it is safe for learners of any age to use.

10Your Privacy Rights

Depending on where you live, you may have rights to access, correct, delete, or port your personal data, or to opt out of its sale. Fretkit makes these rights simple to honor: we hold no personal data about you, so there is nothing to retrieve, correct, or delete on our end, and nothing is ever sold.

California (CCPA/CPRA)

We do not collect, sell, or share personal information as defined by California law, and we do not use it for cross-context behavioral advertising.

Europe & the UK (GDPR / UK GDPR)

We do not process personal data and are not building any profile of you. If you have a question or wish to exercise a right, contact us using the details below and we will respond.

11Changes to This Policy

If we ever change how Fretkit handles information, we will update this page and revise the "Last updated" date above. Material changes will be reflected here before they take effect, and a current copy of this policy always ships with the app.
