Privacy Policy
Last updated: January 2025
1. Who we are
PanelFitCalc (panelfitcalc.com) is a reference calculator for solar energy systems. We are not an installation company or professional advisor. This policy describes how we handle information from visitors to the site.
2. Data we collect
2.1 Data we do NOT collect
PanelFitCalc has no user registration, does not request personal data, and does not send any form data to our own servers. All calculations run entirely in your browser (client-side). The parameters you enter never leave your device.
2.2 Server logs
The site is hosted on Cloudflare Pages. Cloudflare may automatically log standard technical data such as anonymized IP addresses, browser, operating system, and pages visited for security and performance purposes. See Cloudflare's privacy policy.
2.3 Analytics
We currently do not use any analytics tools (Google Analytics, Plausible, etc.). If this changes, this policy will be updated accordingly.
3. Cookies
PanelFitCalc uses only one first-party functional item:
- theme โ stored in
localStorage(not an HTTP cookie). Saves your visual theme preference (light/dark/system). Never sent to any server.
There are no tracking cookies or third-party cookies set by the site itself.
4. Advertising
Advertising on this site may be enabled or disabled depending on server configuration. If advertising is active, it may be served by one or more of the following providers, who may set their own tracking and personalized advertising cookies:
- Google AdSense โ Google Privacy Policy / Ad Settings
- Adsterra โ Adsterra Privacy Policy
- Infolinks โ Infolinks Privacy Policy
If advertising is currently disabled, it may be activated in the future. When that happens, this policy will be updated to clearly reflect it. Ads shown are display and native format only; no pop-unders, push notifications, or redirects are used.
You can opt out of personalized Google advertising at adssettings.google.com.
5. International transfers
By using Cloudflare and the advertising providers listed above, your technical data may be processed on servers outside your country. These providers adhere to recognized transfer mechanisms (SCCs, successor to Privacy Shield, etc.).
6. Your rights
Since we do not directly collect personally identifiable data, we have no records to modify or delete. For requests related to data processed by advertising providers, contact each provider directly using the links in section 4.
