Privacy Policy
By purchasing, installing, or using Sono ScalarMetrics (“the App”) on Android, you agree to this Privacy Policy. If you do not agree, do not use the App. This Policy forms part of, and should be read together with, the Terms of Use.
1. Who we are
The App is published by ScalarMetrics (“ScalarMetrics”, “we”, “us”), an independent software developer. Sono ScalarMetrics is distributed worldwide through Google Play. ScalarMetrics is not a healthcare provider, a medical-device manufacturer, a laboratory, or a clinical service of any kind. Contact details are in Section 22.
2. What the App is — research, educational and reference use only
The App is an offline reference and calculation tool for sonographic (ultrasound) measurements. You manually type or select numeric values (for example an organ dimension, a Doppler velocity, an age band, a sex, or a gestational age) and the App applies published formulas and reference ranges to display derived values such as volumes, ratios, indices, z-scores, percentiles, estimated gestational age, and category or severity classifications, together with explanatory text and literature citations.
The App is provided strictly for research, educational, and informational reference purposes. It is not a medical device, has not received clearance, approval, marking, or registration from any medical-device regulator in any jurisdiction (including but not limited to the FDA, the EU, or any other national or regional authority), and has not been clinically validated. It does not acquire, display, store, or process ultrasound images, DICOM data, or any output of an ultrasound machine. The App must never be used as the sole or primary basis for clinical diagnosis, screening, triage, treatment planning, treatment decisions, prognosis, or any other clinical purpose. All outputs are approximations without clinical warranty and may contain errors. Use of the App does not create a professional or fiduciary relationship of any kind between you and ScalarMetrics, and ScalarMetrics assumes no liability for any decision or action taken on the basis of information displayed by the App.
3. Data processing
The App processes only the numeric values and selections that you type or choose directly within the App during a session. The App does not open, import, scan, or process any file, image, document, sensor, or other data stored on or captured by your device. All calculation and display occur locally, in memory, on your device. No value you enter is ever transmitted to ScalarMetrics or to anyone else.
4. Data we do not collect
The App has no network access of any kind and therefore cannot collect, request, or transmit personal data. Specifically, the App:
- Declares no Internet permission and contains no networking code
- Requires no account, sign-in, name, email address, telephone number, or other identifying information
- Contains no analytics, usage-tracking, attribution, or A/B-testing SDK
- Contains no crash-reporting or automated error-telemetry SDK
- Contains no advertising, ad-measurement, or ad-tracking SDK
- Contains no in-app billing, licensing, or payment SDK; payment is handled entirely by Google Play (Section 7)
- Requests no access to contacts, camera, microphone, location, photos, files, health data, or any permission beyond OS defaults
Because the App collects nothing, ScalarMetrics holds no personal data about you, cannot identify you as a user, and cannot link any activity to you.
5. Do not enter patient-identifying information
The App provides only numeric and categorical input fields, with no free-text field for names, identifiers, dates of birth, or notes, and you must not attempt to record any patient-identifying information by any other means. You are solely responsible for confidentiality/data-protection obligations you owe to any patient or institution.
6. Data stored locally on your device
Written to private app preferences only, never read by ScalarMetrics, never transmitted:
- Display/accessibility preferences: theme, text size, haptics, explanation-visibility toggles, language/locale
- Recently used shortcuts (category/field names only, never values or patient info)
- Measurement values exist only in memory while the screen is open; never written to disk
Android system backup: if enabled on your device, the OS may copy preferences (never values) to your Google backup account, encrypted under Google’s own terms; ScalarMetrics has no access. Disable via device Settings or by clearing app storage (Section 11).
7. Purchase information processed by Google Play
The App is paid, distributed exclusively via Google Play. Google is merchant of record and processes payment, billing address, tax, and payment method under its own terms. ScalarMetrics receives no personally identifying purchase information from Google, only aggregated non-identifying statistics via Play Console. Android/Google Play may separately collect diagnostics under Google’s own settings (e.g., Android Vitals), controlled by Google, not the App.
8. No accounts, no profiling, no sale of data
No sign-in, no profile, no sale/rental/sharing of information, because none is collected.
9. Accuracy and sources of reference content
Reference ranges/formulas are compiled from published literature cited in the App; ScalarMetrics does not continuously re-verify sources and makes no warranty of current clinical consensus. You must independently verify every value before relying on it.
10. Translations and units
Translations are for convenience only; English text prevails in conflicts. You must confirm units match what the App expects.
11. Data retention and deletion
Nothing to retain beyond local preferences (Section 6); clear via Settings > Apps > Sono ScalarMetrics > Storage & cache > Clear storage, or uninstall. No remote deletion process exists since ScalarMetrics holds no data. Google Play purchase/backup requests go to Google.
12. Security
Reasonable measures for a local, offline app; no storage method is completely secure; ScalarMetrics is not responsible for device-level compromise (loss, theft, malware, rooting, OS vulnerabilities).
13. International use
Offered worldwide; all processing is local; no cross-border transmission because none occurs at all. You are responsible for complying with laws applicable to you wherever you are.
14. Permissions
Declares no runtime, special, or Internet permission; relies only on OS defaults.
15. Third-party services and open-source components
No third-party SDK, analytics, ads, or cloud backend, apart from Google Play and Android system backup. Built with open-source libraries (e.g., Jetpack, Kotlin) that run locally.
16. HIPAA, GDPR and other regulatory regimes
Not a HIPAA-covered entity/business associate, not a GDPR “processor”/ “controller”. Not designed for environments requiring such compliance; if used in a clinical/institutional workflow anyway, you bear all compliance responsibility.
17. Children’s privacy
Not directed at individuals under 18; Google Play age rating/parental controls apply; no mechanism exists to receive/store child data.
18. Disclaimer of warranties
Provided “as is”/“as available”, no warranty of accuracy, completeness, currency, merchantability, fitness, or non-infringement.
19. Limitation of liability
No liability for indirect/incidental/special/consequential/punitive damages or personal injury/death; total aggregate liability capped at the price actually paid for the App; carve-out for non-waivable mandatory consumer-protection rights.
20. Changes to this policy
May be modified anytime; effective upon inclusion in an installed App update; continued use means acceptance.
21. Governing law, severability and language
Governed by laws applicable to ScalarMetrics as a company, without regard to conflict-of-law principles, except where your local mandatory consumer-protection law entitles you to your own law/courts. Severability applies. English text prevails over translations.
