Chromic: A World of Stories · Last updated: September 22, 2026

Chromic: A World of Stories ("the app") plays soundwalks by the artist Chromic: music and stories placed at real locations, heard through headphones as you walk. The app is built on and run by Songitude. This policy explains exactly what data is involved.

Your location, in plain terms: the app uses your location only to play the right sounds for where you are standing, and to sort the list of walks nearest first. Your location is used in real time on your device. We do not collect it, send it to our servers, store it, log it, sell it or share it.

Location data

While a walk plays, the app reads your device's location continuously to decide what you hear. This happens on your device. The list of walks is sorted nearest first, also on your device, using your most recent location. Your location is never sent to Chromic, Songitude or anyone else.

Background location

A soundwalk is meant to be heard with the phone locked and in your pocket. So while a walk is playing, the app keeps reading your location with the screen off, for the same single purpose. Location access starts when you press Start and stops when you end the walk, quit the app, or the walk ends. When nothing is playing, the app does not read your location at all.

On Android this runs as a foreground service, which is why a notification is shown while a walk plays. That notification holds the lock-screen controls. It is the only notification the app ever shows. We send no alerts, reminders or messages.

What we store

Nothing about you. There are no accounts and no sign-in. The app stores the walks you download and your settings on your own device, and nowhere else.

Reports you send

If you use Settings → Report to tell us about a problem, the app sends the text you type along with the walk it concerns, the app version and your device model and system version, so we can fix it. Reports carry no name, account, email address, device identifier or location. If you want a reply, include a way to reach you in the message yourself.

No tracking or ads

The app contains no advertising, no analytics or tracking SDKs, and no third-party trackers.

Third-party services

Amazon Web Services (S3, Lambda): hosts the walks and artwork the app downloads, and delivers reports you choose to send. It never receives your location.
Map tiles (OpenStreetMap / CARTO): draw the map on iPhone. Standard tile requests do not include your precise location.
Google Maps SDK: draws the map in the Android app. It requests imagery for the area on screen and is governed by Google's privacy policy.
Google Fonts: serves the typeface used on this website.
Server logs: like any web server, the walk catalog records standard request logs (IP address, file requested, time) when something is downloaded. These are used only to keep the service running and are not linked to you or to your location.

Permissions the app asks for

Location (precise, and in the background): to play the right sounds for where you are, while a walk is playing. See above.
Notifications (Android): only so the playback notification can be shown while a walk plays.
Network: to download walks. Each walk is downloaded in full before you set off, so nothing streams while you walk.

Every permission can be declined or revoked in your device settings. Without location the app can still show you the walks, but it cannot play them where they belong.

Your data, and deleting it

Nothing is stored about you, so there is nothing to delete on our side. Uninstalling the app removes the walks and settings saved on your device.

Children

The app is not directed to children under 13 and does not knowingly collect their data. It does not collect anyone's data.

Changes

We may update this policy. Material changes will appear here with a new date.
