Chords Finder Privacy Policy

Last updated 25 October 2026

Chords Finder is made by Sen Lin. This policy explains what happens to your data when you use Chords Finder on iPhone, iPad and Mac.

What Chords Finder keeps

Chords Finder has no accounts and no servers of its own. Your settings, such as the number of keys, theme and the chord types you practise, are saved only on your device. They are never sent to me.

On iPhone and iPad, Chords Finder is free and shows a banner ad from Google AdMob. The Mac app has no ads.

To show and measure ads, Google may collect:

your device's advertising identifier, but only if you allow tracking when the app asks
your IP address, and an approximate location worked out from it
information about your device, such as its model and system version
how ads are shown and whether you tap them
crash and performance information about the ads

Google handles this data under its own policies. See how Google uses information from apps that use its services and Google's Privacy Policy.

Your choices

Tracking. Chords Finder asks before letting Google use your advertising identifier. You can change your answer at any time in the iOS Settings app, under Privacy & Security → Tracking. If you say no, you'll still see ads, but they won't be based on what you do in other apps and websites.
Consent in the UK, EEA and Switzerland. If you're in one of these places, Chords Finder shows Google's consent form before any ads load. You can change your choices later from the app's Settings screen, using Privacy Settings.
Remove Ads. A one-time Remove Ads purchase turns the ads off for good. After that, Chords Finder doesn't start Google's ad software at all, so Google gets no data through it.

Purchases

Remove Ads is bought through Apple's App Store. Apple handles the payment, and I never see your payment details. The app only checks with Apple whether you own Remove Ads, so it knows whether to show ads.

Ratings

Chords Finder may occasionally ask you to rate it using Apple's standard rating prompt. Apple handles anything you submit there.

Children

Chords Finder is not aimed at children under 13, and I don't knowingly collect data about them.

Changes to this policy

If this policy changes, I'll update this page and the date at the top.
