Privacy

The short version

checkweather.io sets no cookies and has no accounts. We count visits with our own simple measurement, described below, so we can see which pages people use. We do not build a profile of you, and we have nothing to sell or share.

How we count visits

When a page opens, your browser sends us these details: the page address, the site you came from, any campaign tag in the link, your screen width, your time zone, and later how long the page was visible, how far you scrolled, and whether you interacted with it, so we can tell people from automated visitors. We also record links you follow to other sites. Our server adds your country and the type of browser and operating system.

• No cookies: a random session number is kept in your browser tab and disappears when you close it.
• No stored IP address: we store a one-way hash of your IP address and browser details, mixed with a secret and changed every day. It lets us count visitors for that day and cannot be turned back into an IP address.
• Not shared: the numbers stay on our own server and are used only for our own statistics.
• Outside Europe, Cloudflare Web Analytics also counts page loads.

The lawful basis is our legitimate interest in understanding how the site is used, under Article 6(1)(f) GDPR.

Third parties your browser contacts

A web page cannot load without the servers that serve it seeing your IP address. On this site those are:

• Cloudflare hosts and serves the pages, so it processes the request that delivers them.
• Google Fonts (fonts.googleapis.com and fonts.gstatic.com) serves the two typefaces the site uses, which means Google sees the request for those font files.
• Open-Meteo (api.open-meteo.com) is called from your browser to fetch the live forecast shown on city pages.
• RainViewer serves the radar tiles on radar pages.

Each of those sees a normal web request. None of them receives what our own measurement collects.

Comments and the "Was this useful?" vote

Every guide carries a vote button and a comment box. Both are optional, and the rest of the page works without them.

• Comments: we store the name and the text you type, plus the date. Both are published under the guide for everyone to read, so do not put anything sensitive in the box.
• The vote: we store a count only. We do not record which way you personally voted, beyond the fingerprint described next.
• Spam control: to keep bots and repeat votes out, we store a one-way hash (SHA-256) of your IP address combined with the name of the page. The hash cannot be turned back into an IP address.
• Deletion: ask us on the contact page and we will remove your comment.

The lawful basis is our legitimate interest in a working, spam-free discussion, under Article 6(1)(f) GDPR.

Location

If you use a feature that asks for your location, your browser asks you first and the coordinates are used only to look up the nearest place. They are not sent to us or stored.

Links out

We link to national weather services and other sites. Once you follow a link, that site's own privacy terms apply, not ours.
