NoiseMark is developed and operated by Enso Ventures S.à r.l-S, a company registered in Luxembourg ("we", "us", "our"). Our contact address for privacy matters is privacy@ensoventures.org.
NoiseMark measures sound levels and turns the moments that matter into a documented record. You can use the live meter and NoiseMark Pro without an account. Your measurements are held on your device. If you subscribe to NoiseMark Cloud, they are also included in backup archives stored with your account, which you can restore on another device.
NoiseMark never records or stores audio. Sound is processed to calculate a level and the sound itself is discarded. That is the single most important thing to understand about how this app treats your privacy.
An account is optional. You need one to subscribe to NoiseMark Cloud. You can create one with:
We use your account only to identify you, to link your NoiseMark Cloud subscription and backups to you, and to keep your privacy preferences. Profile details such as your name and email are stored only when your sign-in provider supplies them. NoiseMark Pro does not need an account. We do not use it for marketing or advertising.
The following is created by you and held on your iPhone. If you subscribe to NoiseMark Cloud, it is also included in backup archives stored with your account in Google Cloud Storage. You can also export your records yourself at any time, without Cloud:
NoiseMark begins measuring as soon as you open it, but measuring is not saving. The live meter is a rolling 30-second buffer held in memory only. If you never start a Log and never tap Mark, nothing about that session is written down at all.
A single control in Settings governs both. It is on by default, and turning it off stops analytics being sent and crash reports being uploaded, immediately and for good until you turn it back on. We tell you about it when you first open the app, so the choice is in front of you rather than buried.
Analytics and crash reports never contain anything you measured. No sound levels, no coordinates, no notes, no dictated text, no photographs, no place names, no report filenames. They record that something happened and how the app performed, never what you were documenting.
The live meter is free. NoiseMark Pro is a one-time in-app purchase that unlocks Logs, Marks, photos, locations, notes, tags, reports and exports. NoiseMark Cloud is an optional auto-renewing subscription, requiring Pro, that stores backup archives of your records, which you can restore across your devices.
Apple processes every payment. To confirm a purchase, the app sends Apple's purchase receipt to our server for verification. NoiseMark Cloud is linked to your NoiseMark account, so we keep its subscription status against that account. NoiseMark Pro does not require an account: it belongs to your Apple ID and can be restored from the App Store on any of your devices. We never receive your card details.

Your measurements are stored in a database on your iPhone, protected by iOS app sandboxing and by the device encryption applied when your device is locked with a passcode. If you create an account, your account profile, your NoiseMark Cloud subscription status, your privacy preferences and a record of your backups are held in Google Firebase (Firestore). Your measurements and photographs are not stored as records in Firestore: if you subscribe to NoiseMark Cloud, they travel inside backup archives stored in Google Cloud Storage for Firebase, which encrypts stored data by default. These Firebase resources are located in the EU. Other processors listed in section 5, such as Apple and Google's analytics services, may process data in other regions under their own safeguards. Access is controlled by security rules that restrict each account to its own data.
Your account credentials are held by Google Firebase Authentication. We never see your password.
Exported backup archives have no separate password encryption. When you export a backup, the ZIP archive contains your measurements, locations, notes, photographs, Projects and deletion records as a portable file that you own and control. It carries checksums so you can tell whether it has been altered, but those protect integrity, not confidentiality. Store it somewhere you consider secure and treat it as you would any other sensitive document. We chose not to add a password because a forgotten password would mean the permanent loss of your own evidence. Cloud backup copies are separately encrypted at rest by Google Cloud Storage.
| Processor | Purpose | Data shared |
|---|---|---|
| Google Firebase (Authentication, Firestore) | Sign-in, account profile, NoiseMark Cloud subscription status, privacy preferences and backup metadata | Account identifier; email and display name when your sign-in provider supplies them; subscription and backup metadata — not your measurement records |
| Google Cloud Storage for Firebase | Storing NoiseMark Cloud backup archives | Backup archives of your records, photographs included, for Cloud subscribers |
| Google Firebase (Analytics, Crashlytics) | Usage analytics and crash reporting | App events and crash diagnostics only — never measurement content |
| Apple (Sign in with Apple) | Authentication | Apple account identifier and email, or Apple's private relay address |
| Google (Sign in with Google) | Authentication | Google account email and display name |
| Apple (App Store) | Distribution, the Pro purchase and the Cloud subscription | The transaction and its receipt, handled by Apple |
| Apple (MapKit) | Map imagery for a report containing located records | The coordinates needed to fetch that map image |
| Apple (on-device speech recognition) | Transcribing a dictated note | Nothing — transcription happens on your device |
No other third parties receive your data. We do not use advertising networks, data brokers or marketing platforms.
When you export or share a report or a backup, the file contains the coordinates of any located Logs and Marks: the PDF draws them on a map and the CSV lists them as latitude and longitude. That is your own act of sharing, but the coordinates travel with the file, so it is worth knowing before you send one.
If you are in the EU or UK, you have the following rights:
Delete a Log — a deleted Log moves to Recently Deleted, where it stays for 30 days and can be restored. After that it is removed permanently. You can also remove it permanently straight away from within Recently Deleted.
Delete a Mark — deleting an individual Mark removes it from the app immediately. Marks are not covered by Recently Deleted and cannot be restored from there. A copy may remain in an earlier NoiseMark Cloud backup, or in a backup you exported yourself, until that backup is replaced, deleted or expires.
Delete your data — Settings → Delete Data removes your measurements, Marks, photographs, notes, places and Projects, from this device and from your account, including Firestore and any NoiseMark Cloud backups. Your account itself remains, so you can carry on using the app.
Delete your account — Settings → Delete Account permanently and irreversibly removes your account together with all of the above. This cannot be undone.
Deleting your account does not cancel a NoiseMark Cloud subscription. Apple manages subscriptions, so cancel it in your App Store account settings. Your NoiseMark Pro purchase stays with your Apple ID, and you can restore it if you create a new account.
What survives a deletion, and why. Two things do not go, and neither can be used to identify you or to reconstruct anything you measured:
Deleting the app from your iPhone removes the local copy but does not delete your account. Use Delete Account if that is what you intend.
NoiseMark is not directed at children under 16. We do not knowingly collect personal data from children under 16. If you believe a child has provided us with personal data, contact privacy@ensoventures.org and we will delete it promptly.
