Licensor grants the User a non-exclusive, non-transferable, and revocable license to use the Calcumber Web App free of charge for personal, educational, non-commercial, or light commercial purposes.

“Light commercial use” includes internal use within a company, or use by professionals for their own calculations. It does not include redistribution, resale, embedding in other software, or offering Calcumber as a paid service.

• Users may not modify, reverse-engineer, or create derivative works based on the Software.

3. Ownership

The Software is the intellectual property of MFis GmbH. All rights not explicitly granted are reserved.

4. Limitation of Liability

The Software is provided "as is", with no warranties of any kind, express or implied.

In no event shall MFis GmbH be liable for any damages arising out of the use or inability to use the Software — including, but not limited to, loss of data, loss of business, or loss of profit — even if advised of the possibility of such damages.

The Software may integrate with third-party ad networks such as Google AdSense. These providers may use cookies or similar technologies to collect and process personal data for the purpose of delivering personalized ads, in compliance with applicable laws.

Users will be informed and given a choice through a consent dialog before any such data collection occurs.

MFis GmbH does not collect or store personally identifiable data unless explicitly authorized by the user.

Ads will be selected to remain relevant and non-disruptive. MFis GmbH reserves the right to offer optional premium features or an ad-free experience in the future.

Calcumber Web App and Windows App

Calcumber does not collect, transmit, or store any personal or usage data. All calculations are performed locally on your device. No information is sent to external servers.

When using Calcumber’s sharing feature, the generated link includes the calculation input you provided. If you choose to share this link with others, be aware that your input will be visible to anyone who opens the link.

When someone opens a shared link, the calculation is processed entirely in their browser using the Calcumber Web App. The input is never transmitted to the Calcumber server or stored remotely.

Embedded content from other websites

Articles on this site may include embedded content (e.g. videos, images, articles, etc.). Embedded content from other websites behaves in the exact same way as if the visitor has visited the other website.

These websites may collect data about you, use cookies, embed additional third-party tracking, and monitor your interaction with that embedded content, including tracking your interaction with the embedded content if you have an account and are logged in to that website.

How long we retain your data

If you leave a comment, the comment and its metadata are retained indefinitely. This is so we can recognize and approve any follow-up comments automatically instead of holding them in a moderation queue.

You can also request that we erase any personal data we hold about you. This does not include any data we are obliged to keep for administrative, legal, or security purposes.
