NoiseLog Privacy Policy

Last updated: 2026-05-29

NoiseLog is an offline-first noise-incident logging app. This policy explains what the app collects, where it lives, and what (if anything) leaves your device.

1. Short version

Every incident you log — date, time, decibel level, note, photo, audio, location — is stored only on your device in a local SQLite database.
We do not operate any servers. There is no NoiseLog account. Nothing is uploaded to us.
The app uses three OS-level services that you can decline at any time: microphone (decibel capture), camera / photo library (evidence photos), and location (incident geo-tag).
If you choose to share a PDF report, CSV, or JSON export, you decide who receives it via your device’s share sheet.

2. What the app stores locally

Data	Where	Why
Incident metadata (date, time, dB, category, note)	On-device SQLite database	The case log
Photos attached as evidence	On-device file storage (`documentDirectory/photos/`)	The case log
Audio recordings	On-device file storage (`documentDirectory/audio/`)	The case log
Latitude / longitude / accuracy / reverse-geocoded street label	On-device SQLite database	Incident location tag (Pro feature, opt-in)
Case files (name, property, reporter, case number)	On-device SQLite database	Organising incidents
Generated PDF reports	On-device file storage (`documentDirectory/reports/`)	The report vault
App settings (theme, quiet hours, Pro unlock status)	On-device SQLite settings table	Personalisation

None of the above is transmitted to NoiseLog or any third party.

3. Permissions we request

The app asks for these OS permissions only at the moment the feature is used:

Microphone — to measure decibel levels while recording an incident.
Camera / Photo library — to attach a photo as evidence (Pro only).
Location (when-in-use) — to geo-tag the incident as evidence (Pro, opt-in via Settings).

You can revoke any of these at any time in your device’s system settings. The app continues to work without them; the corresponding feature is simply disabled.

4. In-app purchases

NoiseLog Pro is a one-time, non-consumable purchase processed by Apple’s App Store or Google Play Billing. We never see your payment information. Purchase verification happens entirely between your device and the platform store. After a successful purchase, only a local flag (pro_unlocked = true) is written to your device.

5. Crash reporting

If a crash reporter is configured for a release, the app may send anonymous crash diagnostics (stack trace, app version, OS version) to Sentry to help us fix bugs. We strip personally identifying information automatically (sendDefaultPii: false). No incident data, case data, location, audio, photos, or notes are ever included in crash reports.

Crash reporting is fully disabled when no DSN is configured.

When you export a PDF / CSV / JSON or share an audio recording, the app opens your device’s standard share sheet. You choose the destination (email, messaging app, file storage, etc.). NoiseLog has no part in that transmission and keeps no record of it.

7. Children

NoiseLog is not directed at children under 13 and does not knowingly collect data from them. As the app is fully offline and account-less, no data collection occurs regardless of the user’s age.

8. Data retention & deletion

You can delete any incident from its detail screen, bulk-delete from the Records screen, or wipe the entire local database via Settings → Data → Delete all data. Uninstalling the app removes every stored byte.

We retain nothing because we have nothing to retain.

9. Changes to this policy

If we change this policy in a way that materially affects you, we will update the “Last updated” date above and surface the change in the app on next launch.
