Privacy

Windchaser has no accounts, no tracking cookies and no ads. This is everything that gets stored, where, and how to delete it.

In your browser

The app keeps in the browser’s localStorage the spots you follow, the last spot, the minimum wind and the days you picked, whether it has already offered to install itself and, if alerts are on, which spots, minimum wind and days they use. It does not leave your device.

If you pick a language in the footer, a cookie (wc-lang) remembers it for a year. It is the only cookie and is used for nothing else.

To delete all of it, clear the site data in your browser settings.

Alerts

If you turn on alerts, the server stores the browser’s subscription (the address of its push service and the keys to encrypt the messages), your spots, minimum wind, days, time zone, language and which windows it has already told you about. No name and no email.

Turn them off in the settings (the bell) and the subscription is deleted from the server. It is also deleted automatically when the browser drops it.

Visit counter

To know how many people use it, the server counts page views per day, spot and language. To count unique visitors, it hashes the IP and the browser with a key that changes every day and is not kept: the hash cannot be reversed or linked across days. The IP and the browser are not stored. No cookies and no third-party analytics.

If you arrive through a link with ?ref= (from a school, a poster, a message), the server counts the tag and the day’s unique visitors to know where people come from, and sends you on to the address without the tag. Nothing else is kept.

Contact

What you write in the contact form reaches us by email, with your email address and your name if you give it, only so we can reply. The server does not keep it. To slow down spam, it keeps the time of each message for a day, with an encrypted fingerprint of the IP. If you want us to delete the email you sent, just ask.

Webcams and outside data

The forecast is downloaded by the server from Open-Meteo: your browser never talks to it. Many webcams, however, load straight from their own site, which sees your IP just as when you visit it. Each webcam links to its source.

Server logs

Like any website, the server keeps access logs (IP, time, address and browser) to spot errors and abuse. They are deleted automatically after a short time.
