Privacy
Privacy policy
The first release keeps calculator inputs in your browser and does not require an account. This policy describes the limited data the site may still process.
Effective date: July 13, 2026
Calculator inputs
SolarMathKit calculations run in your browser. The site does not send calculator input values to an application server or save them in a database. Results are not tied to an account because the first release has no account system.
Local storage
The site may store your light or dark appearance choice in browser local storage. This preference stays on your device unless you clear it. Calculator inputs are not stored there in the first release.
Hosting and technical logs
The site is delivered through Cloudflare Pages. Like most hosting and network services, Cloudflare may process request metadata such as IP address, time, requested URL, user agent, and security signals to deliver and protect the site. See Cloudflare's privacy policy for its practices.
If you email contact@solarmathkit.com, the message and address are processed so the request can be read and answered. Do not send secrets or unnecessary personal data.
Analytics and advertising
The first release does not include Google Analytics, Google AdSense, ad placeholders, or advertising cookies. If analytics or advertising is added later, this policy and any required consent controls will be updated before those services are enabled.
Your choices
You can clear local storage through your browser, block cookies, or use browser privacy controls. Blocking storage may reset appearance preferences but does not stop the calculators from working.
Policy changes
The effective date will change when this policy is materially updated. Older claims will not be left in place after a new data service is enabled.
