Privacy Policy

1. Information processed

CalcBaro does not require registration. Calculator inputs and files selected for image, PDF or OCR tools are processed only on your device. Selected files are not uploaded to or stored on our server. An address entered in the English-address tool is sent to the official Korean Address Information API for the requested search and is not saved by CalcBaro. The My IP tool returns the public IP and approximate connection metadata in the current request; CalcBaro does not add the displayed IP to its feature-statistics database. Recent calculators, favorites and saved results may be stored in your browser’s local storage.

2. Preferences, offline data and cookies

Language, theme, favorites and saved-calculation preferences may be kept in local storage. If you use installation or offline features, public site files and pages you visited may be stored in the browser cache; you can remove them by clearing site data or uninstalling the app. During operation, security, analytics and advertising, technical data such as IP address, browser, access time and visited page may be processed.

3. Contact form and feature statistics

When you submit the contact form, your name, reply email address, category, message, language and submission time are stored in Cloudflare D1 so we can review and reply. The submitted details are also sent to the operator’s Google Gmail account as a new-message alert. Contact records are reviewed periodically and deleted when they are no longer needed for the inquiry. To improve the service, CalcBaro stores only daily aggregate counts for events such as calculator use, result saving, calendar saving, search and file-tool completion. These event records do not contain your input values, file names, search terms, IP address, cookies or a user identifier.

4. Google advertising

This site may use Google AdSense. Google and other third-party vendors may use cookies to serve ads based on visits to this and other sites.

Manage personalized ads in Google Ad Settings. See Google’s partner-sites policy for how Google uses information.

5. External links

We link to external websites for official calculation standards and references. Those sites apply their own privacy policies.

6. Policy changes

We may revise this policy when the service, law or advertising policies change. Material changes are indicated by the last-updated date.

7. Service information and contact

How calculations are reviewed and how local processing works are described on the About page and the sources page. You can ask a privacy or data-handling question through the contact form.
