FAQ

Quick answers

Do I need an account or an app?
No. Everything runs in your browser with plain HTML, CSS and JavaScript. No sign-up, no app store, no tracking beyond your own browser.
How accurate are the tide predictions?
The tools use a simplified harmonic model (M2 plus S2/K1 constituents). They reproduce the real rhythm — two highs a day, spring-neap swings — but local geography shifts times and heights. Always verify against the official tide table for your exact spot.
Why does every tool have a safety warning?
Because tides genuinely can and do trap people. Coastal rescues spike every summer for the same few reasons. We would rather be repetitive about safety than quiet.
Will this site stay free?
The core tools are free and will stay free. Some advanced features may become members-only later, but favorites, the tide predictor and the safety checks are here to stay.
⚠️

Safety first. These tools are planning aids. Always check official local tide tables, lifeguard advice and on-site signs before you go. Read the full disclaimer
