Terms of Use

Last updated: September 26, 2026

These Terms of Use (these “Terms”) set out the conditions for using the iOS app Kotsu Camera (the “App”) provided by StackWorks (the “Developer”). By using the App, you are deemed to have agreed to these Terms.

1. About the App

The App is a camera that takes photos, gives advice on composition, level, brightness and similar matters, and guides other people when they take a photo for you. The advice is a general guide to taking photos and does not guarantee the results.

2. Photography etiquette and the law

• When taking photos of people or publishing photos, get the consent of the people in them.
• Do not take photos in places where photography is prohibited or where it would disturb others.
• When you hand your phone to someone else with Take My Photo, use your own judgment in choosing who to hand it to and where. The App is not responsible for how the device you hand over is handled.
• Do not take photos while looking at the screen when you are moving (walking or driving). When following tips such as “Crouch down,” make sure your footing and surroundings are safe.

3. Kotsu Camera Plus

The App offers Kotsu Camera Plus, a non-consumable In-App Purchase. The price is the amount shown in the App Store. Purchases and refunds are subject to Apple's terms. Family Sharing is supported. You can restore your purchase on other devices with Restore Purchases.

Shooting, saving and coaching features are available without Plus. Without Plus, Take My Photo can be used up to 3 times a day.

4. Photos and data

You own the rights to the photos you take. How photos and data are handled is described in the Privacy Policy. In case saving to the Photos app fails, please check that your important photos have been saved.

5. Prohibited conduct

You may not use the App in ways that violate laws or public order and morals, use the App in ways that infringe the rights of others (such as portrait rights, privacy or copyright), or reverse engineer or modify the App and redistribute it.

6. Disclaimer

The Developer does not guarantee that the App is free of defects or that it is fit for any particular purpose. The Developer is not liable for any damages arising from the use of the App, except where caused by the Developer's intentional misconduct or gross negligence.

7. Changes and termination

The Developer may change the content of the App or these Terms. Significant changes will be announced on this page or in the App.

8. Governing law

These Terms are governed by the laws of Japan.
