Terms of Use – SoundScope

Effective date: October 18, 2026

1. Not a certified instrument

SoundScope (the "App") applies the IEC 61672 A-weighting curve and fast time weighting, but a phone microphone is built for voice and has no calibrated acoustic reference. Readings carry real error, particularly below 30 dB and above about 100 dB. Don't rely on the App for occupational noise assessment, legal or regulatory evidence, medical judgement, or any decision where an inaccurate reading could cause harm; use a calibrated sound level meter for those. The Adjust control shifts every reading by a fixed offset, and setting it correctly is your responsibility.

2. Free version and ads

The App is free to use with ads. Some features can be unlocked for a limited time by choosing to watch a rewarded ad. If no ad is available, the feature works anyway.

3. Premium subscriptions and purchases

• Premium removes all ads. It is sold through Google Play as a subscription (weekly, monthly or yearly, where offered) or, where offered, a one-time "Lifetime" purchase.
• Prices are shown in the App before you buy, in your local currency, as provided by Google Play.
• Free trial: where a free trial is offered, you are charged at the end of the trial unless you cancel at least 24 hours before it ends.
• Automatic renewal: subscriptions renew automatically at the end of each period until you cancel. You can cancel at any time in Google Play → Payments & subscriptions → Subscriptions; Premium then stays on until the end of the period you paid for.
• Refunds are handled by Google Play under its refund policy.
• Premium is tied to your Google account. Use "Restore purchases" in the App after reinstalling.

4. Acceptable use

Don't copy, modify, reverse-engineer or redistribute the App, or interfere with its ads or purchase checks.

5. No warranty

The App is provided "as is". To the extent permitted by law, we are not liable for any loss arising from the use of the App, including decisions made on the basis of a reading it produced.

6. Privacy

See our Privacy Policy.

7. Changes and contact

We may update these terms; the effective date above shows the latest version. Questions: use the "Contact developer" email on the App's Google Play page.
