These terms apply when you use the Formulens mobile application or website (together, “Formulens”). By using Formulens, you agree to these terms. If you do not agree, please do not use the service.

Using Formulens

Formulens is an educational reference for exploring mathematics formulas and selected visual lessons. You may use it for personal, lawful learning. You agree not to misuse the service, interfere with its operation, or copy and redistribute the app or its original materials except as allowed by law or with permission.

Formulas and mathematical facts are not owned by Formulens. The app, its software, design, illustrations, and original explanatory materials are protected by applicable intellectual-property laws; third-party materials remain subject to their respective licenses and rights.

Educational information

Formulens is provided for general educational purposes. We work to make the explanations useful, but do not promise that every formula, explanation, or lesson is complete, error-free, or suitable for a particular purpose. Check important results against appropriate references.

Offline content, ads, and third parties

The formula catalog is designed to be available on your device. Some lesson downloads and other features require an internet connection. Formulens may display advertising provided by Google or other third parties. Their services and content are governed by their own terms and privacy practices. See our Privacy Policy.

Availability and changes

We may update, change, suspend, or discontinue parts of Formulens, including content, to maintain or improve the service. Formulens is provided on an “as available” basis. To the fullest extent permitted by law, we make no warranties beyond any rights that cannot legally be excluded.

Liability

Nothing in these terms limits liability or consumer rights where applicable law does not allow that limitation. Otherwise, to the fullest extent permitted by law, Formulens is not liable for indirect or consequential loss arising from use of, or inability to use, the service.
