Privacy Policy

1. Information we collect

UnCalculator does not require an account to use the website. Most calculator inputs are processed in your browser and are not submitted to us as part of normal calculator use.

If you contact us by email, we may receive the information you choose to send, such as your email address, message, and any details included in your request.

2. Browser storage & Local Calculation Privacy

UnCalculator uses client-side browser storage (such as localStorage) to save interface preferences and quick utility state. Your financial, medical, or date input numbers stay strictly on your device and are never sent to or stored on our servers.

The specific storage keys utilized by UnCalculator include:

• unc_consent: Stores your cookie consent preferences (necessary, analytics, advertising).
• theme: Remembers your dark/light visual mode preference.
• country: Remembers your selected regional currency and formatting hub (e.g. US, UK, India, CA, AU).
• pinned_calculators: Remembers your bookmarked/favorite calculator cards.
• usage_history: Stores your recent calculation history locally in your browser for convenience.

3. Advertising, Cookies, and Google Consent Mode v2

We use Google AdSense and third-party advertising vendors to serve ads when you visit UnCalculator.com. Google and third-party vendors use cookies (including the DoubleClick DART cookie) to serve ads based on your 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 visit to our site and/or other sites on the Internet. You may opt out of personalized advertising by visiting Google Ads Settings or by visiting www.aboutads.info.

We implement Google Consent Mode v2 alongside Google Analytics 4. When you first visit UnCalculator.com, analytics and advertising storage consent default to denied until you choose to accept analytics or advertising cookies in our consent banner. Under denied consent, Google Analytics processes cookieless pings for aggregate telemetry without reading or writing storage cookies. When consent is granted via our banner, full analytics cookies are activated.

For full details on Google's privacy practices, review the Google AdSense Privacy Policy and the Google Privacy Policy.

4. How we use information

We use information you voluntarily provide to respond to questions, fix calculator issues, improve the website, and maintain the service.

5. Third-party services & Embedded Widgets

UnCalculator uses Google Fonts to display web typography and Cloudflare for content delivery, DDOS defense, and edge routing. When these services load, your browser may transmit technical information such as your IP address to the provider. Each service processes this data according to its own privacy policy, available at Google Fonts Privacy Policy and Cloudflare Privacy Policy.

Embedded Widgets: If you embed an UnCalculator widget on an external site using our /embed/ routes, the iframe widget operates in a privacy-isolated container with zero third-party tracking cookies or advertising scripts.

6. Data security

We use reasonable measures to protect the website and limit unnecessary data collection. No website or internet transmission can be guaranteed to be completely secure.

7. Children's privacy

UnCalculator is not intended to collect personal information from children. If you believe a child has provided personal information, please contact us so we can review and remove it where appropriate.

8. GDPR and CCPA Disclosures & Managing Your Preferences

For users in the European Economic Area (EEA), the UK, and Switzerland, UnCalculator acts as the data controller. We process personal data under legitimate interests (providing calculator logic and rendering ad units) or based on your consent (cookies for personalized ads and analytics). You have the right to access, rectify, or delete your data, or withdraw consent at any time.

For California residents under the CCPA/CPRA, we disclose that we collect identifiers (IP address) and internet/electronic network activity. You have the right to opt-out of the "sale" or "sharing" of your personal information. You can exercise this right at any time by selecting "Decline" in our cookie consent banner.

Resetting Preferences: You can modify or clear your consent preferences and stored calculator history at any time by clearing your browser cookies/localStorage or clicking the "Cookie Preferences" button in our site footer.

9. Changes to this policy

We may update this Privacy Policy from time to time. The updated date on this page will show when the policy was last revised.
