Privacy Policy

Last updated: August 29, 2026

Calculator information

Zelvaniq is designed so that core calculator inputs are processed in your browser unless a particular tool clearly states that it uses an external service. You should not enter sensitive personal information into free-form fields.

Browser storage

Features such as favorites, recent calculators, theme preferences or similar convenience settings may use local browser storage. This information stays associated with your browser unless a feature explicitly says otherwise.

Advertising and cookies

Zelvaniq may use third-party advertising services, including Google AdSense, after advertising is enabled on the live site. Third-party vendors, including Google, may use cookies to serve and measure ads. Google's advertising cookies can be used to serve ads based on visits to this and other websites. Where required, consent choices will be presented before applicable advertising or measurement technologies are used.

Users can manage personalized advertising through Google's Ads Settings and applicable browser or consent controls. If additional advertising vendors are enabled, this policy should be updated to identify them and explain available choices.

External services

Some tools may request public data from an external provider, such as current currency exchange-rate data. Those requests can be subject to the provider's own privacy and technical practices.

Policy updates

This policy may change as Zelvaniq adds analytics, advertising, consent tools or other services. The current version and update date will be published on this page.

Contact

Questions about this policy can be sent through the Contact page.

Contact form submissions

If you submit the contact form, the information you enter is transmitted through the site hosting/form service so the message can be delivered and reviewed. Do not submit sensitive personal information.

Google advertising disclosures

If Google advertising is enabled, third-party vendors including Google may place and read cookies in your browser or use web beacons, IP addresses or similar identifiers to serve, measure and personalize ads as permitted by your consent choices and applicable law. Users can manage personalized advertising through Google Ads Settings.
