Software License Agreement & Calculation Disclaimer

Effective date: October 23, 2026 · Agreement version: 2026-10-23

This Software License Agreement and Calculation Disclaimer (the “Agreement”) governs your use of PhauksCalc for Android (the “App”), published under the name PhauksWorks (“PhauksWorks,” “we,” or “us”). PhauksWorks is a publishing name, not a representation that a separate limited liability company has been formed. Questions about the identity of the publisher may be directed to the contact address below.

Acceptance and changes

When the App presents this Agreement for acceptance, selecting “I Agree & Continue” indicates that you agree to its terms. If you do not agree, select Exit and do not use the App. The App may request renewed acceptance when material terms change. We may publish revised terms with a new effective date; changes do not retroactively alter rights or obligations where doing so is prohibited by law. Your rights under applicable law remain unaffected.

License to use PhauksCalc

Subject to this Agreement and applicable law, you receive a limited, personal, non-exclusive, non-transferable license to install and use the App on devices you own or control, consistent with applicable Google Play terms. The App is licensed, not sold, except where applicable law provides otherwise. You retain ownership of your own formulas, documents, and other content.

Except where applicable law or applicable open-source licenses allow it, you may not redistribute proprietary portions of the App, misrepresent its origin, remove proprietary notices, or use PhauksWorks names and logos in a way that falsely suggests endorsement. This paragraph does not restrict lawful reverse engineering, interoperability, or other rights that cannot be waived.

Calculation results and appropriate use

PhauksCalc is a general-purpose calculation and text-editing tool. Results can be inaccurate or incomplete because of input mistakes, expression interpretation, formulas, settings, rounding, numerical precision, units, software defects, device behavior, or other factors. You are responsible for reviewing inputs and evaluating whether results are suitable for your intended use.

Independently verify consequential calculations using a separate reliable method before relying on them for financial, engineering, scientific, medical, safety-related, regulatory, or other important decisions. PhauksCalc is not certified or represented as suitable for safety-critical or regulated systems, and should not be the sole basis for decisions that could cause injury, significant financial loss, or property damage.

Not professional advice

Functions for financial, statistical, scientific, conversion, date/time, programmer, or other calculations do not constitute financial, investment, tax, accounting, legal, medical, engineering, or other professional advice. Consult an appropriately qualified professional where professional judgment or compliance is required.

Your content and backups

You are responsible for the formulas, expressions, variables, custom functions, notes, documents, keyboard definitions, and other content you create or import. Keep independent copies of information that matters to you. The App is not a guaranteed archival or backup service; information may be lost or become inaccessible due to device failures, software defects, deletion, or other events.

Optional Pro purchase

PhauksCalc may offer optional Pro features through a Google Play in-app purchase. Purchase processing, applicable refunds, and payment handling are subject to Google Play requirements and applicable consumer law. Purchasing Pro grants access to the applicable paid functionality under this Agreement; it does not guarantee uninterrupted service, permanent availability of every feature, or error-free results. Nothing here reduces any statutory purchase, refund, or consumer rights.

Ownership and third-party components

PhauksWorks and its licensors retain their respective rights in the App, branding, and proprietary materials. PhauksCalc may include Qt and other third-party or open-source components governed by their own licenses. Those licenses control the components to which they apply and take precedence over any conflicting restriction in this Agreement. Applicable notices and license materials will be made available as required by those licenses.

Availability, updates, and changes

We may update, correct, change, add, or remove features, subject to applicable law and purchase obligations. We do not guarantee compatibility with every device, Android version, file, formula, workflow, or third-party service, or that updates will always be available.

Disclaimer of warranties

To the fullest extent permitted by applicable law, the App is provided “as is” and “as available,” without express or implied warranties, including implied warranties of merchantability, fitness for a particular purpose, and non-infringement, where such disclaimers are permitted. We do not guarantee accuracy, completeness, uninterrupted operation, availability, or freedom from errors. Some jurisdictions do not allow certain warranty exclusions; in those jurisdictions, those exclusions apply only to the extent legally permitted.

Limitation of liability

To the fullest extent permitted by applicable law, PhauksWorks and the persons responsible for publishing the App will not be liable for indirect, incidental, special, consequential, exemplary, or punitive damages, or for lost profits, lost data, business interruption, or losses resulting from reliance on calculation results, arising from or relating to the App.

To the fullest extent permitted by applicable law, the aggregate liability arising from or relating to the App will not exceed the greater of (a) the amount you paid for the App or its Pro features during the 12 months before the event giving rise to the claim or (b) US $25. This limitation applies only where legally enforceable and does not exclude or limit liability for fraud, intentional misconduct, personal injury, or any other liability that applicable law prohibits limiting. Nothing in this Agreement restricts non-waivable statutory or consumer rights.

Applicable law and severability

This Agreement is intended to be interpreted consistently with applicable law. If a provision is found unenforceable, the remaining provisions will continue to apply to the extent permitted by law. This Agreement does not impose mandatory arbitration or waive rights to participate in a class action.
