Building a Privacy-First Weather Tool

A weather tool does not need to know who you are. Ours is built so that the only thing that ever leaves your browser is the location you ask about.

No accounts, no ads, no SDKs

There is nothing to sign up for and nothing to install. The page carries no advertising and no third-party analytics SDKs — the kind that quietly follow you around the web. The honesty row on the tool says exactly that: free, no tracking, no ads, forecast by Open-Meteo.

The minimum data, by design

To return a forecast the tool must send a location to Open-Meteo — that is unavoidable for any live weather service, and we say so plainly rather than pretending it is offline. But that is the whole story: we send coordinates, get a forecast back, and render it. Your unit preference and last city are stored locally on your device, not on a server. By contrast, the Moon and Sun tools are pure maths and never call out at all.

What that means in practice

Open your browser's network panel while the tool runs and you will see exactly two kinds of request: the page's own static files, and calls to Open-Meteo carrying a latitude and longitude. There is no analytics beacon, no tag manager, no font or pixel loaded from a tracking domain, and the tool sets no cookies of its own. Geolocation is only ever read after you tap Use my location and grant the browser prompt — nothing asks for it on load.

The trade-off we accepted

Living without analytics means we cannot see which cities people search or which days get read, so the tool improves from feedback rather than from telemetry. We think that is the right trade for a page you might open while standing outside your own front door.

Use a weather forecast that doesn't track you.
