Privacy Policy

Values entered into calculators

Dates, prices, text, raffle entries, and other values entered into our tools are processed in your browser. Unless you use the result-sharing feature, those values are not sent to or stored by Pattobako.

Shared results

When you share a result from a supported calculator, the price, percentage, quantity, unit, or other values needed to recreate the calculation are included in the shared URL. That URL may remain with the person or service you share it with and in browser history.

A hosting provider may handle the full URL as part of delivering the page. Do not enter names, contact details, or other personal information into a shareable calculator. Text and raffle entries are not included in shared URLs.

Website access data

This site is hosted by Netlify. To deliver and secure the site, Netlify may handle information such as IP addresses, device and browser details, access times, and requested URLs. Calculator inputs are not part of that information unless they are present in a shared URL.

See Netlify's Privacy Policy for details.

Contact form

We use Google Forms for messages. When you submit the form, Google receives the inquiry type, page URL, message, and any optional reply-to email address you provide. The site operator can review those responses.

We use submissions to respond to messages, investigate bugs, and improve calculators and content. A reply-to email address is optional and is used only when a response is needed. The form is not configured to collect your Google Account email address automatically.

See Google's Privacy Policy for details.

Analytics and advertising

If you consent, we use Google Analytics to understand how the site is used and to improve its pages. Google Analytics may collect page views, session information, device and browser details, approximate location, and similar usage data. It uses first-party cookies such as “_ga” to distinguish users and sessions.

Before a page URL or referrer is sent to Google Analytics, we remove its query parameters and page fragment. This prevents values in shared-result URLs from being included. We also do not send calculator inputs as custom analytics events.

See Google's Privacy Policy for details. Pattobako does not currently run advertising.

Links to other websites

Pattobako is not responsible for how another website handles information after you follow an external link. Review that site's privacy policy before providing information.

Changes to this policy

We may update this policy when the site or its external services change. Important changes will be posted on this page.
