Terms of Use
Last updated: September 6, 2026
This translation is provided for reference only. If it differs from the Japanese version, the Japanese version prevails.
These Terms of Use (the “Terms”) govern your use of the iOS app “Takasa” (the “App”). By downloading or using the App, you agree to these Terms.
The App is also subject to Apple Inc.’s Standard End User License Agreement. These Terms supplement that agreement; where the two conflict, the Standard EULA prevails.
1. What the App Does
The App estimates the height of buildings, trees and similar objects using your iPhone’s camera, motion sensors and step counter, calculating the result by trigonometry.
2. Accuracy Disclaimer
The heights shown by the App are approximate. Differences from the true height arise from, among others:
- Sloped or uneven ground
- Variation in stride length and error in step counting
- Error in the camera height estimated from your body height
- The precision of the device’s motion sensors and unsteadiness in how the device is held
- Difficulty in sighting the top or identifying the base of the target
Depending on conditions, the error can reach tens of percent. Do not use the App for surveying, construction, engineering, safety verification, legal proceedings, or any other purpose requiring accuracy. The developer accepts no liability for damages arising from such use.
3. Safety
Using the App involves walking outdoors. Pay full attention to traffic, terrain and the safety of others, and do not walk while looking at the screen. Do not enter private property or otherwise violate laws or the rights of third parties. The developer accepts no liability for accidents or damages arising from such conduct.
4. Advertising
The App is provided free of charge and displays third-party advertising (Google AdMob) to cover its operating costs. The developer is not responsible for the content of those ads or for your dealings with advertisers. For how advertising-related data is handled, see the Privacy Policy.
5. Prohibited Conduct
You may not:
- Copy, modify, adapt or create derivative works of the App
- Reverse engineer, decompile or disassemble the App
- Redistribute, lend or sell the App or any part of it
- Interfere with or alter the display of advertising
- Use the App in violation of law or public order
- Interfere with the operation of the App
6. Intellectual Property
All intellectual property rights in the App, including its code, design, text and illustrations, belong to the developer or the respective rights holders. These Terms do not transfer any of those rights to you.
7. Disclaimer of Warranties
The App is provided “as is”. The developer does not warrant that the App will suit your particular purpose, achieve any expected level of accuracy, operate without interruption, or be free of defects.
Except where liability cannot be excluded by law, the developer is not liable for any damages arising from your use of, or inability to use, the App.
8. Changes and Discontinuation
The developer may change the App or discontinue it at any time without prior notice.
9. Changes to These Terms
The developer may revise these Terms as needed. Revised Terms take effect when posted on this page.
10. Governing Law and Jurisdiction
These Terms are governed by the laws of Japan. Any dispute relating to the App or these Terms shall be subject to the exclusive jurisdiction of the Tokyo District Court as the court of first instance.
