Questions and answers
Practical Tools FAQ
Are these tools free?
Yes. Every practical tool on 73hi is free to use with no signup and no daily limit.
Is my data uploaded?
No. The zodiac lookup, the bead art studio, the hand match and the dice roll all run in your browser, so nothing you enter is sent to the 73hi server.
Why is the zodiac lookup on its own page?
The zodiac tool now has a dedicated page with the full twelve year cycle table, its own instructions and FAQ, so it is easier to find and explains the lunar calendar rules properly.
Do the tools work on mobile?
Yes. All the tools are responsive and work in any modern mobile browser.
