Privacy Policy

No account, no server — which leaves the ads

Effective 4 October 2026 · Applies to the Duskvale mobile app for iOS and Android

The short version

Duskvale has no account, no sign-in and no server. The sounds ship inside the app and the mixing happens on your phone; we collect, store and transmit nothing about who you are. No data reaches us — there is nowhere for it to reach.

That leaves one thing: the app is free and covered by advertising. The ads are served by Google AdMob, which needs access to some data on your device in order to serve them. Exactly what that involves is set out under Advertising below.

What we collect

Nothing. The app sends no data to us: no e-mail, no username, no identifier, no usage log. We operate no server and no database.

The app stores two things on your phone:

• The interface language you picked — when you choose a language in Settings, it is written to your phone's own local storage so the app remembers it next time.
• Your favourite mixes — for each mix you add to favourites, which recordings play and at what volume. They sit in the same local storage.

Neither ever leaves the device. The colours you add from the wheel are not saved at all; they live in memory while the app is open and are gone when you close it.

Permissions

Duskvale asks for no location, microphone, camera, contacts, photo or file permission. On Android it declares these permissions:

• Internet access — purely so the ads can load.
• Foreground service (media playback) and notifications — so the sound keeps playing when you switch apps or lock the screen. While sound is playing, a Duskvale notification shows in the notification shade and you can stop playback from there. On Android 13 and later the notification permission is asked on first play; if you decline, the sound still plays, only the notification is hidden.

We cannot reach what we never asked for.

Advertising

There is one banner ad above and one below the mixer screen; the visualiser has no ads. The ads are served by Google AdMob.

To select an ad, AdMob accesses some data on your device. None of it passes through us — it goes straight to Google:

• Your advertising ID — the IDFA on iOS, the Advertising ID on Android. A number with no connection to your name, which you can reset from your phone's settings.
• Your IP address — used to decide which country and language the ad should be chosen for. Not street-level location.
• Device information — model, operating system version, screen size, language.
• Ad interaction — which ad was shown and whether it was tapped. Used to avoid showing you the same ad repeatedly and to filter out fraudulent clicks.

We see none of this and we link it to no identity — we have no account to link it to. All that reaches us in the AdMob console is anonymous aggregate reporting of how many impressions there were. You can read why and how Google processes this data in their advertising data policy.

The ad SDK does its own measurement as part of serving ads. Beyond that there is no analytics library and no crash-reporting service in the app: which layer you open, how long you use the app and which screen you stop on are recorded nowhere. There are no in-app purchases either.

Your consent for ads

The first time you open the app, if your region requires it, Google's consent screen asks whether you want personalised ads. On iOS you also get Apple's “allow the app to track you” prompt.

If you say no, you still get ads, but they are not personalised — they are chosen by the country you are in rather than by your history. The app behaves identically either way; no layer and no feature is turned off.

You can change your mind later:

• In regions where the consent form is required, the app's Settings screen shows an Ad privacy options row that reopens the form.
• The route that works everywhere is your phone's settings: Settings › Privacy & Security › Tracking on iOS, Settings › Google › Ads on Android. You can reset or delete your advertising ID from the same place.

Deleting your data

Removing the app from your phone removes everything the app holds — that is, your language preference and your favourites.

App stores

Duskvale is distributed through the Apple App Store and Google Play. As part of running those stores, Apple and Google collect their own download and usage statistics under their own privacy policies. Only anonymous aggregate reports reach us.

Children

Duskvale is not directed at children, and we knowingly collect no data from them — we collect no data from anyone. If you want to limit what the ads can show on a phone a child uses, your phone's parental controls and the advertising ID settings above will do it.

Your rights

Data protection law such as the GDPR and Turkey's KVKK gives you the right to access, correct, port and erase your personal data, and to object to its processing. In practice those rights have nothing to bite on here, because we store nothing about you. For the data Google processes for advertising, Google is the counterparty; you can withdraw consent and reset your advertising ID through the settings above. If something still looks wrong, write to us and we will come back within 30 days.

Changes to this policy

If a future version changes what the app stores or transmits, this page is updated before that version ships, and the effective date above changes with it.
