Privacy Policy

Information you provide

If you contact us, we receive the information in your message and your reply address. If you create an account, authentication and account details are processed so we can provide sign-in, saved calculations, bookmarks, preferences, and related account features.

Calculator inputs may be stored locally in your browser so a tool can remember your work. Unless you explicitly use an account feature that saves data, those local inputs are not sent to Hannav as a saved financial profile.

Local storage and cookies

Hannav uses browser localStorage for selected tool inputs, recent searches, and limited convenience state. You can remove this data through your browser settings or the relevant reset control in a tool. We do not use localStorage to silently upload your financial data.

Authentication and security features may use cookies. A browser translation preference may also set a Google Translate cookie when you choose translation. Blocking cookies can affect sign-in or some site functionality.

Third-party advertising and Google AdSense

Hannav works with third-party advertising partners, including Google AdSense, to serve ads when you visit our website.

• Third party vendors, including Google, use cookies to serve ads based on a user's prior visits to our website or other websites on the Internet.
• Google's use of advertising cookies (such as the DoubleClick cookie) enables it and its partners to serve ads to users based on their visit to Hannav and/or other sites across the Web.
• Users may opt out of personalized advertising by visiting Google Ads Settings. Alternatively, users can opt out of a third-party vendor's use of cookies for personalized advertising by visiting www.aboutads.info.

Analytics and technical information

We may process aggregate usage information such as pages viewed, search activity, device and browser details, approximate timing, and error diagnostics. We use this to improve reliability, content, and product performance. Analytics providers may process this data on our behalf according to their own terms and privacy practices.

Error reports are designed to exclude passwords, financial values, and other sensitive user information. Please do not include sensitive information in support messages or URLs.

How we use information

• To operate, secure, and maintain Hannav.
• To provide account features you request.
• To answer support requests and investigate technical problems.
• To understand aggregate usage and improve our content and tools.
• To meet legal obligations and prevent abuse.

Retention, sharing, and security

We retain information only for as long as reasonably needed for the purposes above, legal requirements, or legitimate operational records. We do not sell personal information. We may share limited information with service providers that help operate the site, or when required by law. We use reasonable technical and organizational safeguards, but no online service can guarantee absolute security.

Your choices

You can clear local browser data, manage cookies in your browser, and request help with account or personal information by emailing [email protected]. We may need to verify a request before acting on it.

Changes to this policy

We may update this page as Hannav changes. The date above identifies the latest revision. Continued use of the site after an update means the revised policy applies going forward.
