These Terms of Use govern your use of Tacet, published by Chasie Andajao ("we", "us"). By downloading or using Tacet you agree to them. Apple's Standard End User License Agreement also applies to the app.
Contents
Tacet measures sound with your phone's microphone, keeps a diary of noise incidents, logs events during a night watch and creates reports.
Tacet is not a certified sound level meter. Readings from a phone microphone are indicative; calibrate against a reference meter for the best accuracy. The reference limits in the app are public guidance values, not a legal assessment. Do not rely on Tacet for occupational safety, hearing protection or medical decisions.
The free version includes the full meter, calibration, reference limits, the diary of the last 7 days and weekly patterns. Tacet Pro adds the full history, night watch, audio clips, PDF and CSV reports and patterns over longer periods.
Tacet Pro is offered as a weekly or yearly auto-renewing subscription, which may start with a free trial, or as a one-time lifetime purchase. Prices are shown in the app before you buy. Payment is charged to your Apple Account when you confirm the purchase.
A subscription renews automatically unless it is cancelled at least 24 hours before the end of the current period. Your account is charged for renewal within 24 hours before the end of the period. Manage or cancel subscriptions in Settings › your name › Subscriptions. Any unused part of a free trial ends when you buy a subscription.
Purchases are handled by Apple. Refund requests go to Apple at reportaproblem.apple.com.
What you create in Tacet is yours and stays on your device. You are responsible for using measurements, recordings and reports lawfully, including any local rules about recording sound where other people can be heard.
Tacet is provided "as is", without warranties of any kind, to the extent permitted by law.
To the extent permitted by law, we are not liable for indirect or consequential damages, or for decisions made on the basis of readings, limits or reports produced by the app.
If these terms change, the new version is published on this page with a new date below.
