This Privacy Policy applies to Tacet, the sound level meter and noise diary for iPhone and iPad ("Tacet", "the app"), published by Chasie Andajao ("we", "us"). Tacet works on your device. It has no account, and we run no server for it.
Contents
We do not collect personal data. The measurements, diary entries, notes, places, audio clips and reports you create are stored only on your device, inside the app, and never reach us.
Tacet uses the microphone to measure the sound level around you. The level is computed on the device in real time. Sound is kept only when you turn on audio clips (Tacet Pro): each clip is saved as a file inside the app on your device. Nothing is uploaded.
Only when you tap "Attach location" while saving a diary entry does Tacet read your location once, to add the address to that entry and to your reports. It is stored with the entry on your device. We do not receive it.
Tacet Pro subscriptions and the lifetime purchase are processed by Apple through the App Store. We do not receive your payment details. Apple's privacy policy applies to that processing.
Tacet shows no ads, contains no analytics or tracking, uses no third-party software that collects data, and neither sells nor shares any data.
Your data stays on your device and in the device backups you make with Apple's services. When you export a PDF or CSV report or a clip through the share sheet, you choose where it goes. Delete entries in the app, or delete the app to remove all of its data.
Tacet is not directed to children under 13 and collects no personal data from anyone.
If this policy changes, the new version is published on this page with a new date below.
