Privacy
Last updated 14 November 2026.
Short version: this site has no accounts, no ads and no analytics, and it does not receive what you type into the tools.
Who runs this site
Shogo Makishima is a pen name. One person makes these tools. To reach me, write to @makishima1984 on X.
What the tools save, and where
Tools that remember things between visits save what you type in your own browser's storage, on your own device. That data is not sent to me. The site has no server of its own and no database.
Backup files are made by your browser and saved to your device. Photos you open in the Image Resizer and messages you paste into the Scam Message Checker are processed inside your browser and are not uploaded.
What this site does not do
- No accounts and no login.
- No ads.
- No analytics or tracking scripts.
- No cookies set by this site.
Hosting
The site is hosted on GitHub Pages. GitHub says that when a GitHub Pages site is visited, the visitor's IP address is logged and stored for security purposes. I cannot see those logs. GitHub explains how it handles data in the GitHub privacy statement.
Offline copy
So the tools open with no internet, your browser saves copies of this site's own pages on your device. It saves nothing from other sites. Clearing this site's data in your browser removes those copies.
Links to other sites
Some pages link to other sites, such as YouTube, Instagram, X, course providers and science agencies. When you follow a link, that site's own privacy rules apply.
Deleting your data
The trackers have a button to delete everything they saved. You can also clear this site's data in your browser settings. I hold no copy of your data, so there is nothing for me to delete.
Changes
If this page changes, the date at the top changes with it.
