Privacy notice: how FlipCalc handles your data

FlipCalc is operated by Maciej Dudziak IT Services in Poland. Questions or privacy requests can be sent to maciejdzk@gmail.com. Include enough detail to identify the request, but do not send passwords, payment information, marketplace credentials, or other sensitive information.

Calculator values are processed in your browser to produce estimates. FlipCalc may use local storage or session storage for functional features such as saved calculator inputs, a recently viewed list, dismissal state, and a session calculation count. This browser storage is tied to the device and browser profile you use.

You can remove this data through your browser's site-data controls. Blocking browser storage may reset preferences but should not prevent you from reading the public content.

Google Analytics is an optional measurement service. Its scripts are not requested unless you select “Accept analytics” in the privacy choice shown on the site. If you decline, that choice is stored locally and the analytics scripts remain off.

When accepted, analytics can process page views, device and browser information, approximate location derived from an IP address, referral information, and deliberately limited interaction events. FlipCalc does not send calculator prices or item costs as analytics event values. Google acts as a separate service provider under its own privacy terms.

The hosting and delivery infrastructure may process standard request logs, including IP address, requested URL, timestamp, user agent, response status, and diagnostic information. This processing is necessary to deliver pages, investigate errors, prevent abuse, and maintain site security. Retention is controlled by the hosting provider and operational needs rather than by a public user profile.

FlipCalc does not currently operate an email-alert signup. The site links to a public fee-change page and RSS feed instead, and does not treat a browser-only email entry as a subscription. If you contact the business directly, the message and address you provide are used to reply and maintain an appropriate business record.

You may decline optional analytics, clear local browser data, block cookies or scripts, and contact the operator to ask about personal data submitted directly. Depending on applicable law, you may have rights to access, correct, erase, restrict, or object to processing and to complain to a data-protection authority.

Privacy practices can change as the product or its service providers change. Material updates will be reflected by the date on this page. For calculator assumptions and limitations, read the methodology.

FlipCalc is intended for a general audience and is not designed to knowingly collect personal data from children. If you believe a child has submitted personal information through a direct contact message, ask the operator to review and remove it where appropriate.
