At SolarROI Calculator (accessible at solarcalculator.online), we believe privacy is a fundamental right. This Privacy Policy details our data practices and demonstrates our commitment to transparency.
1. Client-Side Computational Privacy
All calculations performed on SolarROI Calculator (such as system sizing, electricity bill inputs, and roof square footage) run entirely inside your device's browser using client-side JavaScript. We do not store, log, or transmit your individual calculation inputs to our servers.
Region and state defaults on your initial visit are inferred client-side from standard browser signals (language locale and timezone); no IP-geolocation lookups are performed and no location data is collected, transmitted, or stored on our servers.
2. Cookies & Advertising Disclosures (Google AdSense)
Third-party vendors, including Google, use cookies to serve ads based on a user's prior visits to our website or other websites on the internet.
- Google's use of advertising cookies enables it and its partners to serve ads to users based on their visits to our site and/or other sites on the Internet.
- Users may opt out of personalized advertising by visiting Google Ads Settings.
- Alternatively, you can opt out of third-party vendor cookies for personalized advertising by visiting aboutads.info.
3. CCPA / CPRA & GDPR Rights
We do not sell personal information or share personal data with third-party data brokers. Visitors from the European Economic Area (EEA), United Kingdom, and California hold full rights under GDPR and CCPA to access or request deletion of any telemetry data collected via standard server access logs.
