Privacy
In short
No advertising, no tracking cookies, no third-party analytics. The site only sets cookies needed to run it and for your settings.
Server logs
On every request the web server stores the usual log data (IP address, time, requested address, browser) for operation and security.
Visitor statistics
The site counts visits itself, without cookies and without third parties: page, language, device type (phone, tablet, desktop), referring website and which features are used. To count visitors per day, a non-reversible value is computed from IP address, browser and date and kept only for today and yesterday; for browsers with conspicuously many requests (monitoring, bots) until checked. Only daily totals are kept.
Cookies
These cookies are technically required or store a setting you choose yourself:
| Name | Purpose | Duration |
|---|---|---|
| wetter-tessin-session | Session (needed for forms and security) | until 4 hours after the last request |
| XSRF-TOKEN | Protection against forged forms | until 4 hours after the last request |
| wt_lang | Chosen language | 1 year |
| wt_nerd | Nerd mode switch (0/1), also for the usage statistics | 1 year |
| wt_auto | Marks the automatic reload of the start page (not counted as a page view) | 30 seconds |
In addition your browser stores a few display settings locally (nerd mode, chosen chart, home screen hint, open panels). They stay on your device.
Data from other providers
Weather and lake data (Open-Meteo, Alplakes) are fetched by the server; your browser does not connect to these services. Links to other sites open them directly. Embedded content on the Info page is loaded directly from the respective provider.
