SoundPrint

Unless noted, features apply to iPhone and Android.

1. Users must be at least 13; users under 18 need a parent or legal guardian to have agreed to the terms on their behalf.
2. SoundCheck submissions and account data are hosted on SoundPrint's servers (Heroku hosting); submissions are kept indefinitely, de-identified after account deletion.
3. Covers SoundCheck ambient audio recordings only: if the user opts in to Audio Consent, recordings may be given to hearing aid manufacturers and audio-AI companies to build and test machine-learning algorithms. With Audio Consent off, no audio is recorded.
4. Developer-maintained provider list; it also names analytics (Google Firebase Analytics), crash reporting (Bugsnag, Firebase Crashlytics), push (OneSignal moving to Firebase Cloud Messaging) and newsletter (Mailchimp moving to Brevo) providers.
5. Only when the user turns on Audio Consent; with it off, a SoundCheck records no audio and only sound-level figures are submitted. Consent can be turned off in the app's settings.
6. Venue search terms and approximate location go to venue-data providers; SoundCheck submissions (levels, tags, comments) go to SoundPrint's database.
7. By email request to privacy@soundprint.co (not an in-app control). Turning Audio Consent off does not delete earlier recordings, and recordings already provided to a third party cannot be recalled.
8. In-app under Settings, or by email. Submissions, comments and nominations are kept, de-identified. Users without an account can request deletion of their device record by email.
9. By email request to privacy@soundprint.co; the policy states this right for users anywhere in the United States (response within 45 days). No self-serve export is documented.
10. Single exploratory survey (2018) of 2,376 New York City restaurants and bars measured with the iPhone app; authored by SoundPrint's founder (affiliation 'Sound Print'); includes a side-by-side accuracy check against a Type-1 meter. It is not an independent or randomized evaluation.
11. The 2018 paper's methods describe the measurement procedure (dBA slow response, minimum 15-second measurements, venue averages) and the accuracy comparisons used for the iPhone app.
12. Built-in phone microphone; Bluetooth audio devices (including hearing aids) should be switched off during the measurement, and nothing should be plugged into the phone.
13. Only the decibel meter needs this hardware; venue search, by-ear ratings and the rest of the app work on other Android phones too.
14. Approximate phone-microphone measurement; disable conflicting Bluetooth audio routes as documented. It is not a professional sound-level meter.
15. The built-in meter is documented for Samsung Galaxy S-series flagship phones. Other Android phones use subjective venue ratings.
16. Measurements are shared by submitting them to SoundPrint's public crowdsourced database (venue averages shown in the app and on the website); the user's own submissions appear under My Submissions. No file export of personal measurements is documented.
17. Venue coverage and measurements vary by city, time and phone.
