Privacy Policy

01 Information We Collect

PremiumCalculators is designed to be as privacy-friendly as possible. We collect only the minimum information necessary to operate the service and serve relevant advertising.

Information we do NOT collect:

• We do not require you to create an account or register
• We do not collect your name, email address, or phone number
• We do not store the numbers you enter into any calculator
• We do not sell or rent your personal data to third parties

Information that may be collected automatically:

• Browser type and version (via standard server logs)
• Approximate geographic location (country/city level, via IP address)
• Pages visited and time spent (via Google Analytics, if enabled)
• Referring website (the site you came from)
• Device type (desktop, tablet, mobile)

02 How We Use Information

Any automatically collected information is used solely for the following purposes:

• To operate and improve the PremiumCalculators service
• To understand which calculators are most used so we can prioritise improvements
• To serve relevant advertisements through Google AdSense
• To monitor and protect against abuse, fraud, or technical errors
• To comply with legal obligations

We do not use your information for automated decision-making or profiling that produces legal or similarly significant effects on you.

03 Google AdSense & Advertising

PremiumCalculators uses Google AdSense to display advertisements. AdSense allows Google to serve ads based on your prior visits to this website and other sites on the internet.

Google may use cookies and web beacons to collect information about your visit in order to provide advertisements about goods and services that may be of interest to you. This is known as interest-based advertising.

• Google's use of advertising cookies enables it and its partners to serve ads based on your visit to PremiumCalculators and/or other sites on the internet
• You may opt out of personalised advertising by visiting Google Ads Settings
• You can also opt out via the Network Advertising Initiative opt-out page
• For EU/EEA users, Google will seek your consent before serving personalised ads in compliance with GDPR

04 Cookies

Cookies are small text files stored on your device. PremiumCalculators uses cookies for the following purposes:

• Preferences: We store your chosen theme (dark or light mode) in your browser's localStorage so it persists between visits
• Recently Used: The calculators you've recently opened are stored in localStorage on your device only — this data never leaves your browser
• Advertising: Google AdSense sets cookies to serve personalised advertisements
• Analytics: If Google Analytics is enabled, it sets cookies to measure traffic and usage patterns

You can control cookies through your browser settings. Disabling cookies will not prevent you from using PremiumCalculators, though advertising may become less relevant and some preferences will not be saved.

05 Third-Party Services

PremiumCalculators uses the following third-party services, each governed by their own privacy policies:

• Google AdSense — Advertising platform. Google Privacy Policy
• Google Fonts — Font delivery (Inter and DM Mono). Google's servers receive your IP address when fonts load. Google Privacy Policy
• Google Analytics (if enabled) — Website traffic analytics. Google Privacy Policy

We are not responsible for the privacy practices of these third-party services. We encourage you to review their privacy policies.

06 Data Storage & Security

PremiumCalculators is a client-side web application. Your calculator inputs are processed entirely within your browser and are never transmitted to our servers.

The only data stored locally on your device (via localStorage) is:

• Your theme preference (dark or light mode)
• Your recently used calculators list (up to the last 10)

This data is stored solely on your device and is not accessible to us. You can clear it at any time by clearing your browser's site data or localStorage.

While we take reasonable precautions to protect the security of our website, no internet transmission is completely secure. We cannot guarantee the security of data transmitted to or from our site.

07 Children's Privacy

PremiumCalculators is a general-purpose tool suitable for all ages. We do not knowingly collect personal information from children under the age of 13 (or under 16 in the EU/EEA).

If you are a parent or guardian and believe your child has provided us with personal information, please contact us and we will take steps to delete such information.

Google AdSense has its own policies regarding advertising to children. For more information, see Google's policies on child-directed content.

08 Your Rights

Depending on your location, you may have certain rights regarding your personal data:

• EU/EEA (GDPR): Right to access, rectification, erasure, restriction of processing, data portability, and the right to object to processing
• California (CCPA): Right to know what personal information is collected, right to delete, right to opt out of the sale of personal information (we do not sell personal data)
• All users: Right to opt out of personalised advertising via Google Ads Settings

Since we collect minimal personal data and store nothing on our servers about individual users, most requests can be fulfilled by clearing your browser's localStorage and opting out of Google personalised ads.

To exercise any rights, contact us at the address below.

09 Changes to This Policy

We may update this Privacy Policy from time to time to reflect changes in our practices, technology, legal requirements, or other factors.

When we make changes, we will update the "Last updated" date at the top of this page. We encourage you to review this policy periodically. Your continued use of PremiumCalculators after any changes constitutes your acceptance of the updated policy.
