Sound Meter is an offline decibel meter and noise-logging app,
published by BotSquash. This policy explains how the app handles information.
Short version: no account, no login, no ads, no analytics or tracking SDK of
any kind. Your microphone is used only to compute a sound-level number in real time
— it is never recorded, saved as audio, or transmitted anywhere. Only the resulting
numbers you choose to log stay on your own device.
Sound Meter does not collect, transmit, or share any personal data.
It has no account and no servers of its own. Logged sessions are stored only in a
local database on your device, and the app makes no internet connection at all.
Microphone
Sound Meter uses your device's microphone to estimate the ambient sound level in
decibels.
Audio is processed in memory, in short windows, purely to compute a
number. The app never records, saves, or stores raw audio, and never
transmits audio anywhere.
Only the computed decibel readings — not audio — are
optionally saved if you start a logged session.
The microphone is released whenever the app is in the background and only
reactivated while the app is open and in use.
This is an estimate, not a certified measurement. Phone
microphones are not calibrated like professional sound-level meters. Do not rely
on readings from this app for legal, regulatory, or workplace-compliance purposes.
Data we collect directly
None.
The app has no account or login.
Logged sessions (start/end time, minimum/average/maximum decibel readings, and
any note you add) are stored only on your own device. They are
never uploaded to us and never leave your phone unless you choose to export them
and share them yourself.
We do not see, receive, or store any of this data.
The app does not use analytics, crash reporting, or tracking
SDKs.
The app does not use the advertising ID and contains
no ad network — there are no ads anywhere in Sound Meter, free or
paid.
The app makes no internet connection at all — this is
verified directly in the app's own release build, not just stated here.
Export
Sound Meter Pro lets you export a logged session as a PDF (summary, graph, and
note) or CSV (raw readings). The app itself never uploads or transmits your export
anywhere — it only hands the file to whatever destination you pick via Android's own
share sheet. Nothing is exported unless you explicitly tap Export.
Permissions
Microphone (RECORD_AUDIO): used only to compute
the live decibel reading, as described above. Never used for any other purpose.
The app does not use location, contacts, camera, or any
cross-app identifier.
In-app purchase
The one-time Sound Meter Pro unlock (unlimited session history, PDF export, CSV
export — one-time price, shown in Google Play at checkout) is sold and processed
entirely through Google Play Billing. We never see or store your
card or payment details. The app only stores a local flag on your device recording
that the unlock is active.
Children
The app collects no personal data from anyone, including children. It is a
general-audience utility, not directed at or marketed to children.
Changes
If this policy changes, the "Last updated" date above will change. Continued use
of the app means you accept the current policy.
