Privacy Policy

1. Information We Collect

We are committed to collecting only the minimum data necessary to operate and improve our service.

1.1 Information You Provide

Smart Solver Online does not require you to create an account or provide any personal information to use our calculators. If you contact us via the contact form or email, we collect only the information you voluntarily submit (e.g., your name and email address) solely to respond to your enquiry.

1.2 Automatically Collected Information

When you visit our website, certain technical information may be collected automatically, including:

• Your browser type and version
• Operating system
• Referring URLs and pages visited on our site
• Date and time of access
• Approximate geographic location (country/city level, derived from your IP address)
• Device type (desktop, tablet, mobile)

This information is collected in aggregate and is not linked to any personally identifiable individual.

1.3 Calculator Inputs

All calculations performed on Smart Solver Online are processed entirely within your web browser. The numbers and values you enter into any calculator are never transmitted to our servers, stored in any database, or shared with any third party.

2. Cookies & Local Storage

We use cookies and browser local storage for the following limited purposes:

• Theme preference: We save your chosen colour theme (e.g., Retro Classic, Dark Neon) in your browser's localStorage so it persists between visits. This data stays on your device and is never transmitted.
• Analytics cookies: Google Analytics sets first-party cookies (e.g., _ga, _gid) to distinguish unique visitors and track session metrics. These cookies do not contain personally identifiable information.
• Advertising cookies (future): We may in future serve ads through Google AdSense. AdSense may set cookies to serve personalised or contextual advertisements based on your browsing activity.

You can control and delete cookies at any time through your browser settings. Disabling analytics cookies may limit our ability to improve the site but will not affect your ability to use any calculator.

3. Third-Party Services

3.1 Google Analytics

We use Google Analytics 4 (GA4) to understand how visitors interact with our site. GA4 collects anonymised usage data and reports it in aggregate form. Google may process this data in accordance with Google's Privacy Policy. You can opt out of Google Analytics tracking by installing the Google Analytics Opt-out Browser Add-on.

3.2 Google AdSense

We may display advertisements served by Google AdSense. Google, as a third-party vendor, uses cookies to serve ads based on a user's prior visits to our website and other sites on the Internet. Users may opt out of personalised advertising by visiting Google's Ads Settings.

3.3 Google Fonts

Our site loads typography from Google Fonts (fonts.googleapis.com). This results in a network request to Google's servers when the page loads. Please refer to Google's Privacy Policy for details on any data Google may collect as a result.

4. How We Use Your Information

We use the limited information we collect for the following purposes only:

• To understand overall visitor behaviour and improve site performance and usability
• To respond to your enquiries or feedback submitted via the contact form
• To identify and fix technical errors or performance issues
• To comply with applicable legal obligations

We do not sell, rent, or trade your personal information to any third party for marketing purposes.

5. Data Retention

Contact form submissions (name and email) are retained only as long as necessary to address your enquiry, typically no longer than 12 months. Analytics data is retained in accordance with Google Analytics default settings (up to 14 months). Theme preferences stored in your browser's localStorage remain on your device until you clear your browser storage.
