Tools FAQ
Are the tools free?
Yes. Every Veterinário Raiz tool is free and runs right in your browser, with no sign-up.
Is my data or location saved?
No. Everything runs in your own browser. If you use your location on the tide chart, it is only used to sort stations by distance and is never sent to a server.
Where does the data come from?
Each tool cites its source. The tide chart uses NOAA's published harmonic constants for each station and Meeus's astronomical formulas for the sun and moon.
Can I use the tide chart for navigation?
No. It is an astronomical prediction for planning a fishing trip. For navigation, always use NOAA's official tide predictions.
