Privacy Policy

This policy explains how ONULSURI uses information, cookies, analytics, and advertising services.

Calculator information

Calculator inputs are processed in your browser. We do not intentionally send raw calculator values, financial amounts, email addresses, or user identifiers to Google Analytics or Google AdSense.

Cookies and similar technologies

We use browser storage for essential site functions, including your theme preference. Restricted administrator areas may use secure authentication cookies. With permission where required, Google services may use cookies or similar technologies for analytics and advertising.

Google Analytics 4

We use Google Analytics 4 to understand aggregated site usage, such as which public pages are visited. Analytics events use page paths without query strings and do not include calculator entries or the contents of emails you send to our contact addresses. Google may process device, browser, approximate location, and interaction information for this purpose.

Google AdSense

We use Google AdSense to support the site through advertising. Google and participating ad technology providers may process information and use advertising cookies to deliver, measure, limit, or personalize ads where permitted by your choices and applicable law.

Google and other service providers

Google processes information under its own terms and privacy policies. Learn more about how Google uses information from sites that use its services and manage Google advertising choices in Google Ad Settings. Other ad technology providers disclosed through the Google consent message may also process information according to their own policies.

Consent and legal basis

For visitors in the European Economic Area, the United Kingdom, and Switzerland, our Google-certified consent management platform asks for choices where consent is required for analytics storage, advertising storage, ad user data, and ad personalization. These purposes default to denied until the platform supplies an applicable choice. We rely on consent where required and on legitimate interests for essential site operation, security, and fraud prevention where applicable.

Changing or withdrawing consent

Where the Google consent message applies, use the Cookie settings control in the footer to reopen it and change or withdraw your choices. You can also clear cookies in your browser or use Google Ad Settings. Withdrawal does not affect processing that occurred before the change.

Retention

We retain only the information needed to operate and secure the site for an appropriate period. Google Analytics and AdSense retention periods are controlled through the relevant Google product settings and Google policies. We do not promise a single retention period for data controlled by third parties.

Children's privacy

ONULSURI is intended for a general audience and is not directed to children under 16. We do not knowingly request personal information from children through the public calculators.
