What runs in your browser
Every tool on this site — the Strato and Firework Frappuccino calculators, the fire weather dashboard, the moon phase lookup — runs entirely client-side. Your size, milk selection, location request, and birthday date never leave your device.
Network calls the site makes
The site itself does not call any of our servers. The only outbound calls the site makes are:
- Google Fonts — used for typography. Google may collect standard usage data per their privacy policy.
- Open-Meteo Air Quality API — called by the fire weather dashboard to fetch AQI for your coordinates. Goes directly from your browser to Open-Meteo's servers.
- Open-Meteo Forecast API — called by the fire weather dashboard to fetch temperature, humidity, wind, and precipitation.
- get.geojs.io — called only as a fallback if you deny geolocation. Returns a coarse city-level lookup based on your IP.
Cookies and accounts
We do not use cookies for tracking. We do not require accounts. We do not run advertising networks, analytics platforms, or third-party trackers on the site.
Your location
The fire weather dashboard reads your location once, only when you load the page, and only to fetch AQI for that point. Your coordinates are never sent to Prefertools (we have no server to send them to). The Open-Meteo calls go directly from your browser to Open-Meteo's servers.
Children's privacy
The site is intended for general audiences. We do not knowingly collect information from children under 13.
Changes to this policy
If we make material changes to this policy, we will update the "last updated" date at the top of this page. The page itself contains the current version.
