Privacy Policy for VidMoLyze
Last updated: November 8, 2026

VidMoLyze ("the app") is a video motion-analysis tool designed for physics education. This policy explains what data the app accesses and how it is used.

Summary

VidMoLyze does not collect, store, transmit, or sell any personal data of its own. All video recording, analysis, and data processing happen entirely on your device. Your videos, tracking points, and analysis data are never sent to us or to any third party unless you choose to share them. The one exception is the banner advertising described under "Advertising" below.

Camera and Photo Library Access

VidMoLyze requests two permissions:

• Camera access — used to record videos of motion directly within the app for analysis.
• Photo Library access — used only if you choose to select a video you already recorded outside the app (for example, in your device's Camera app). This lets you import that video for tracking and analysis.

These permissions are used solely to let you capture or select video content for your own analysis. VidMoLyze does not access, scan, upload, or share any other content in your photo library, and it does not use this access for any purpose beyond letting you choose or record a video.

Data Export

VidMoLyze allows you to export the results of your analysis (position, time, velocity, and acceleration data) as a CSV file. This export is generated entirely on your device and is shared using Apple's standard share sheet — meaning you control where the file goes (for example, saving it to Files, emailing it to yourself, or opening it in another app). VidMoLyze does not automatically upload or transmit this data anywhere.

Data Storage

Videos, tracking points, and analysis data are stored locally on your device. VidMoLyze does not use cloud storage, remote servers, or third-party analytics services.

Advertising

VidMoLyze is free and shows a banner advertisement at the bottom of the recordings list screen. No ads are shown on the camera, calibration, origin and axes, tracking, or export screens.

Ads are provided by Google AdMob through the Google Mobile Ads SDK. To show an ad, the SDK sends a request to Google that may include information such as your device's IP address, device and operating system information, and ad interaction and diagnostic data. VidMoLyze requests non-personalized ads only and does not ask for permission to track you across other companies' apps and websites.

Google's use of this information is governed by Google's Privacy Policy (see also How Google uses information from sites or apps that use its services). VidMoLyze does not share your videos, tracking points, or analysis data with Google or any advertiser.

Links Outside the App

The app's About screen includes links to this website and to an optional donation page. These open in your web browser and are governed by the privacy policies of those sites. The feedback form linked from this website is a Google Form; anything you submit through it is handled by Google under its own policies.

Children's Privacy

Because the app does not collect, transmit, or store any personal information on any server, it does not knowingly collect personal information from children or anyone else. All content generated in the app (videos, tracking data, exports) stays on the user's own device unless the user chooses to share it. The only third-party service in the app is the non-personalized advertising described above.

Changes to This Policy

If this policy changes, the updated version will be posted on this page with a revised "Last updated" date.
