Privacy Policy

1. Overview & Data Privacy

OmniCalc is built as a zero-login, private calculator suite. We do not require you to create an account, register an email address, or provide personal identifiers.

When you enter numbers into our calculators (including loan balances, salary figures, body measurements, or tax estimates), all processing occurs locally within your web browser. These numeric inputs are never transmitted to our servers or stored in remote databases.

2. On-Device Storage & Local Data Protection

To provide a seamless, account-free experience, we utilize secure on-device local storage technologies for essential user preferences:

• everycalc_favorites_v1: Locally bookmarked calculators.
• everycalc_recent_v1: Recently visited calculator shortcuts.
• everycalc_history_v1: Private on-device calculation logs.
• everycalc_preferences_v1: User interface display themes (dark/light) and preferred currency defaults.
• everycalc_currency_cache_v1: Temporary local exchange rate cache to eliminate redundant network requests.
• everycalc_consent_v1: User privacy and advertisement consent preferences.

This data resides strictly on your physical device. It is never synchronized to cloud servers or accessible by third parties. You may reset or erase these records anytime directly through your browser settings or via the "Clear History" button in your favorites dashboard.

3. Google AdSense & Third-Party Cookies

OmniCalc is monetized through third-party advertising partners, including Google AdSense. Google and third-party vendors use cookies to serve ads based on your prior visits to this website or other sites 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.

4. Web Analytics

We use Google Analytics 4 to collect aggregated, anonymized metrics (such as page views, device types, and search keywords) to understand how the platform is used and improve calculator accuracy. We do not transmit sensitive calculation inputs or personally identifiable information (PII) to analytics servers.
