What you type
Every tool does its calculations in your browser. The values you enter are never sent to a server, and ToolLamp doesn’t store them.
What this site doesn’t do
- No Google Analytics or any other analytics or tracking scripts.
- No accounts. The tools never ask for your name, email or other personal details; only the feedback form has an optional email field (see below).
- No ads at the moment.
Data stored in your browser
The site remembers three choices in your browser’s localStorage:
- If you use the light/dark switch at the top of the page: “light” or “dark”.
- If you switch between Chinese and English: “zh-tw” or “en”, so the home page opens in that language next time.
- If you add a tool to your favorites: which tools you picked (for example “life/bmi-calculator”), shown under “My favorites” on the home page.
Before you pick a language, the site reads your browser’s language setting and time zone to decide whether to show Chinese or English first. This happens in your browser and nothing is sent anywhere.
These values stay on your device, are never sent anywhere, and are removed when you clear the site’s data. The site sets no cookies.
“Copy favorites link” puts your list of favorites in the link (for example /en/?fav=life/bmi-calculator), so others only see it if you share the link. Opening such a link sends the address to GitHub Pages, as with any page. The site asks before adding the tools, and only stores them after you agree.
Third-party services
To load the site, your browser connects to the services below. They receive your IP address and other standard connection details, and handle them under their own policies:
- GitHub Pages hosts the site. GitHub may log visitors’ IP addresses for security purposes. See the GitHub General Privacy Statement.
- Google Fonts serves the heading font. See the Google Privacy Policy.
Feedback form
The feedback links at the bottom of every page, below the tools and on the contact page open a Google Form in a new tab. What you fill in is only sent to Google when you follow the link and submit the form. It is then stored in the site maintainer’s Google account and used only to fix problems and reply to you. When opened from one of these links, the form fills in that page’s address (for example /en/life/bmi-calculator/); it never includes the values you entered in the tool. The email field is optional. Google handles form data under the Google Privacy Policy.
Affiliate links
Some Chinese tool pages have a “recommended products” box below the tool with affiliate links to Shopee Taiwan, marked as affiliate links; English pages have none yet. The box is part of the page itself and loads no script from Shopee or anyone else. If you follow one of these links, you go to the merchant’s site, which may use a cookie to record that you came from ToolLamp so it can pay a commission. That happens on the merchant’s site under its own privacy policy. ToolLamp only sees the click and sales totals the merchant reports, never your name or contact details.
Ads in the future
The site may add Google AdSense ads later. This policy will be updated before that happens. Google and its partners may then use cookies to show ads based on your visits to this and other sites. Google explains how it uses cookies in advertising, and you can turn off personalized ads in your Google ad settings.
Changes and contact
Any change to this policy will be posted on this page with a new date above. For questions, see Contact.
