Terms of use
Last updated 14 November 2026.
These tools are free to use. By using them you agree to the points below.
1. Free, and provided as they are
These are early versions. They can contain mistakes and they can change or stop working. They come with no guarantee of any kind.
2. Not professional advice
- Calorie and protein values are approximate. They are not medical or diet advice.
- The Period Tracker shows an estimate. It is not medical advice and it is not contraception.
- The Medicine Log records doses and cannot remind you. Follow your doctor or pharmacist.
- The EMI and SIP calculators do arithmetic only. They are not financial advice.
- The Scam Message Checker can miss scams. It never tells you a message is safe.
3. Your data
What you type is saved on your own device (see Privacy). Keeping a backup is up to you: clearing your browser data deletes what you saved.
4. Who owns what
The code, text, page designs and original puzzles on this site are © 2026 Shogo Makishima, all rights reserved unless a page says otherwise. You may use the tools freely, for personal use or for work. Please do not copy, republish or sell the site or its code without written permission.
What you make with the tools is yours: your saved data, your backup files, your edited images and the website files you download from the Shop Website Maker.
5. Other people's names
Names of games, shows, foods, companies, courses and organisations belong to their owners. They appear here only to describe things. This site is not affiliated with them or endorsed by them. Facts taken from public sources are credited on the page that uses them.
6. Liability
As far as the law allows, I am not liable for loss or damage that comes from using these tools.
7. Reporting a problem
If something is broken, or you believe something here uses your work without permission, write to @makishima1984 on X. I will look at it promptly.
8. Changes
If these terms change, the date at the top changes with them.
