Privacy & cookies
Last updated: 2026
This page describes what happens to information when you use SunPathly. It is written to be read rather than to be legally impenetrable, but it is intended to be accurate. If anything here is unclear, the safest assumption is the one that gives you more privacy, not less.
The short version
- All sun, shadow and daylight calculations run inside your browser. Nothing about your location, your room dimensions or your garden layout is sent to us.
- We do not have accounts, and we do not ask for your name or email address.
- Typing into the location search sends that text to a third-party geocoding service so it can be turned into coordinates.
- Advertising is served by a third party and does use cookies. You are asked before any advertising cookie is set, and you can decline.
What stays on your device
The solar position algorithm, the shadow geometry and every chart you see are computed in JavaScript in your browser. There is no server-side calculation, so there is no request carrying your coordinates anywhere.
Your chosen location, your unit preference, your theme, and any garden or room layout you
build are stored in your browser's localStorage so the tools remember them next
time. That storage is local to your device and is never transmitted. Clearing your browser's
site data removes it entirely.
The location search
When you type a place name into the search box, that text is sent to the Open-Meteo geocoding API to be converted into a latitude, longitude and timezone. Open-Meteo receives the text you typed and, as with any web request, your IP address. We do not send them anything else, and we do not receive anything back beyond the matching places.
If you would rather not use it, both alternatives avoid the service entirely: enter coordinates directly, or use the "Use my location" button, which reads your device's own position and never leaves the browser.
Your browser's geolocation always asks your permission first, and we never store the result anywhere but your own device.
Advertising cookies
These tools are free and are paid for by advertising. Adverts are supplied by Google AdSense, which sets cookies to measure and, if you allow it, personalise what you see.
On your first visit you are asked to choose. If you select "Essential only", the advertising script is not loaded at all. If you select "Accept all", advertising cookies are set by Google under their own privacy policy. Your choice is recorded in local storage so you are not asked repeatedly, and clearing site data will make the prompt reappear.
Google's handling of that data is described in their policy for partner sites, and personalised advertising can be controlled at My Ad Center.
Analytics
This site uses Cloudflare Web Analytics to count page views. It sets no cookies, stores nothing on your device, does not fingerprint you and does not track you across other websites. It records the page requested, the referring page, and coarse details such as country and browser type. Because it holds no personal data and sets no cookies, it is not covered by the consent prompt.
No other analytics or tracking scripts are loaded. Standard web server logs may record requests, including IP addresses, as is normal for any website; they are used for operating and securing the site and nothing else.
Children
This site is not directed at children, does not knowingly collect information from them, and has no accounts or profiles of any kind.
Your rights
Because we hold no personal data on a server, there is nothing for us to export or delete on request. The data that exists is in your own browser and under your own control. For the advertising cookies, your rights are exercised through the consent prompt and through Google's own controls linked above.
Changes
If this policy changes materially, the date at the top of this page changes with it.
