Sono ScalarMetrics · Last updated September 16, 2026

PLEASE READ THESE TERMS OF USE CAREFULLY BEFORE PURCHASING OR USING SONO SCALARMETRICS. BY PURCHASING, INSTALLING, ACCESSING, OR USING THE APP, YOU AGREE TO BE BOUND BY THESE TERMS. IF YOU DO NOT AGREE, DO NOT PURCHASE OR USE THE APP AND, IF YOU HAVE ALREADY PURCHASED IT, REQUEST A REFUND FROM GOOGLE PLAY WITHIN THE PERIOD ALLOWED BY ITS REFUND POLICY.

1. Acceptance of Terms

Binding agreement between you and ScalarMetrics, an independent software developer distributing the App worldwide through Google Play; incorporates the Privacy Policy by reference; organisational users must have authority to bind their organisation.

2. Description of the App

Offline reference/calculation tool: you manually enter measurement values and patient context; the App applies published formulas/reference ranges/classification rules to produce volumes, ratios, indices, z-scores, percentiles, estimated GA, and severity grades with explanatory text and citations. Does not connect to any ultrasound machine, does not display/store images, does not store entered values. A calculator/reference library, not a diagnostic system.

3. Eligibility and Intended Users

Must be 18+; intended for qualified healthcare professionals, trainees under supervision, students, educators, researchers, not for public self-diagnosis/self-treatment.

4. Research, Educational and Reference Use Only, Not a Medical Device

Not clinically validated, no regulatory clearance/approval/marking/registration anywhere (including FDA or EU). Must not be sole/primary basis for diagnosis, screening, triage, prognosis, treatment, patient care, or pregnancy management. All outputs are approximations that may contain errors; every output must be independently verified; reliance is entirely at your own risk.

5. No Professional Relationship; No Medical Advice

No physician-patient or other professional/fiduciary relationship created; ScalarMetrics does not practise medicine/sonography/nursing; not a substitute for a qualified professional’s independent judgment.

6. Purchase, Price and Refunds

Paid, one-time purchase exclusively via Google Play; Google is merchant of record for currency/tax/payment. All refunds go through Google Play’s policy; otherwise purchases are final and non-refundable (subject to non-waivable consumer rights). ScalarMetrics may change future pricing; no current in-app purchases/subscriptions/ads; future paid features get separate terms.

7. Licence Grant

Limited, personal, non-exclusive, non-transferable, non-sublicensable, revocable licence tied to the purchasing Google account and devices you own/control, for lawful research/educational/professional reference use. Licensed not sold; no ownership conveyed; single purchase doesn’t authorise institutional/multi-user deployment without separate written agreement.

8. Restrictions on Use

You agree NOT to:

9. Accuracy, Third-Party Sources, Translations and Units

No guarantee that cited sources remain current/complete/error-free or applicable to your population/equipment; translations are convenience-only (English prevails); you must confirm units and verify every output against current guidance.

10. Updates, Availability and Discontinuation

ScalarMetrics may (not obliged to) release updates; may add/remove/change content and behaviour; may condition continued use on updating; may modify/suspend/discontinue the App or its availability in any country anytime without liability (subject to non-waivable consumer rights); no maintenance/support/compatibility obligation.

11. Intellectual Property

App content, design, trademarks, source code, algorithms, texts, translations, and reference-data compilation are ScalarMetrics’ exclusive property, protected by copyright/trademark/database law and international treaties; underlying scientific facts/formulas remain their original authors’/publishers’ property; no rights granted beyond the Section 7 licence.

12. Feedback

Any feedback you send grants ScalarMetrics a perpetual, irrevocable, worldwide, royalty-free licence to use it without compensation; you warrant feedback contains no patient-identifying or third-party confidential material.

13. User Responsibilities and Compliance

You are solely responsible for complying with all applicable laws/regulations/professional standards, including HIPAA, GDPR, PIPEDA, and institutional/review-board requirements for any patient-related or research use; you warrant lawful use.

14. Export Control and Sanctions Compliance

You warrant you’re not in/from an embargoed country/region, not on any sanctions list, and won’t violate export-control/sanctions law.

15. Disclaimer of Warranties

“AS IS”/“AS AVAILABLE”; disclaims merchantability, fitness, accuracy, completeness, reliability, currency, non-infringement; no warranty of uninterrupted/error-free operation or correctness of any output; some jurisdictions may not allow these exclusions.

16. Limitation of Liability

No liability for indirect/incidental/special/consequential/punitive damages, personal injury/death, misdiagnosis, delayed treatment, or professional-liability claims arising from use, errors, reliance on output, unauthorized device access, or discontinuation; total aggregate liability capped at the price paid to Google Play; carve-out for non-waivable mandatory law.

17. Indemnification

You indemnify ScalarMetrics against claims/damages/costs (incl. attorneys’ fees) arising from your use, breach of Terms, violation of law/third-party rights, harm claims from your use of App output, or third-party reliance on information you gave them; ScalarMetrics may assume defence at your expense; survives termination.

18. Assumption of Risk

Use is at your sole risk; you assume all risk that any formula/threshold/range/translation is outdated, mis-transcribed, or inapplicable; no output may be relied on alone for a health decision.

19. Force Majeure

No liability for failure/delay/unavailability caused by acts of God, disaster, epidemic, war, unrest, labour dispute, Google Play/Android platform failure or policy/API changes, utility failure, or government action.

20. Relationship of the Parties

May be modified anytime; effective upon inclusion in an installed update; continued use means acceptance; disagreement’s only remedy is to stop using/delete the App.

Requires 30-day good-faith informal resolution notice before any proceeding. One-year limitation period on causes of action (to the extent permitted by law).
