ShutterFinder Privacy Policy

Last updated: November 13, 2026

1. INTRODUCTION

ShutterFinder ("the App") is developed by Apps on Set. This privacy policy explains how we handle your data.

2. DATA WE COLLECT

ShutterFinder has no account system and shows no ads. It never collects your name, email address, location, photos or anything else that identifies you, and it never asks for permission to track you.

Anonymous usage statistics:
- When a measurement finishes or is cancelled: the outcome (for example the detected flicker frequency, the recommended shutter speed and the frame rate you selected) and how long the measurement took.
- Whether the "How's ShutterFinder working out?" question was shown, and which answer was chosen.
- Basic technical information such as the app version, iOS version and device model.

These are sent with a random identifier that is not linked to you, collected through TelemetryDeck. Nothing is sent from test builds.

Ad measurement (from version 1.6.1):
We advertise ShutterFinder on Facebook and Instagram. To see whether those ads lead to installs, the App includes Meta's Facebook SDK, limited to app events. When you install and open the App, it tells Meta that ShutterFinder was installed and opened, together with basic technical information (app version, iOS version, device model, language and time zone) and a random identifier created by the SDK. It does not send your name, email address, location, photos, video or measurements, and it does not read your device's advertising identifier (IDFA). Apple's SKAdNetwork reports installs that came from an ad to Meta without identifying you. Meta handles this data under its own privacy policy: https://www.facebook.com/privacy/policy
This only happens when your App Store account is outside the European Union, the European Economic Area, the United Kingdom and Switzerland. There, the Meta SDK is never started.
Nothing is sent from test builds.

3. CAMERA

The app uses your iPhone's camera solely to measure light flicker in real time. All processing happens on your device - no images or video are ever saved, uploaded, or shared.

4. MEASUREMENTS

Your measurements are processed on your device. Only the anonymous outcome described in section 2 is sent - never an image, a video or your location.

5. THIRD-PARTY SERVICES

- TelemetryDeck: anonymous usage statistics (see section 2). No personal data, no tracking.
- Meta (Facebook SDK): install and app-open measurement for our ads (see section 2). No advertising identifier is collected and the App never asks for tracking permission.
- Your purchase is handled entirely by Apple through the App Store - we never receive or store your payment details.

6. CHILDREN

The app is not directed at children under 13. We do not knowingly collect data from children.

7. CHANGES

We may update this policy from time to time. Changes will be reflected in the "Last updated" date above.
