Terms of Use

Effective 2 September 2026 · Dimma for iPhone

The short version. Dimma is a sound machine. Every night you get 15 free minutes with everything. If you want more, you pay once and it is yours on any iPhone signed in with your Apple ID. There is no subscription. Dimma treats nothing, and it is your job to keep the volume kind to your ears.

1. Who you are agreeing with

These terms are an agreement between you and Frekvens AS, Norway (“we”, “us”), the developer of Dimma (“the app”). By downloading or using the app you accept them. The app is distributed through Apple's App Store, so Apple's Licensed Application End User License Agreement also applies. Where these terms say more than Apple's, ours apply between you and us; Apple is not a party to these terms and has no obligation to provide support for the app.

2. Your licence

We grant you a personal, non-exclusive, non-transferable licence to install and use the app on Apple devices you own or control, as permitted by the App Store's usage rules. You may not copy, modify, distribute, sell, rent, reverse-engineer or otherwise extract the app's source or sound engine, except where the law expressly allows it.

3. The free minutes

Every night the app gives you 15 minutes of playback with every colour and every control, free of charge. When the free window ends, the sound fades out over about a minute and the app shows the pay-once screen. “Not now” is a real exit. The window resets each night. We may change the length of the free window for new users in future versions; we will not remove the free window without notice.

4. The one-time purchase

5. What Dimma is not

Dimma is a noise-colour sound machine. It is not a medical device, it does not diagnose, treat, cure or prevent any condition, and nothing in the app or on this website is medical advice. If you have tinnitus, hyperacusis, hearing loss or another hearing or sleep concern, or if your symptoms are new or changing, talk to a doctor or an audiologist. Words like “ringing relief” describe a sound control, not a treatment.

6. Hearing safety

Loud sound for long periods can damage hearing, whatever the source. You are responsible for the volume you choose. Keep the level low: just below your ringing, or just over the room. A speaker is generally kinder than earbuds for many hours. Do not use the app in a way that keeps you from hearing alarms or other sounds you need to hear.

7. Availability and changes

We may update the app, add or change colours and controls, and fix bugs. We may stop distributing the app if we have to, though we will do our best to keep an app you have paid for working on the iOS versions it supported when you bought it. The app depends on your device, your iOS version and Apple's services, none of which we control.

8. Warranty and liability

The app is provided “as is”. To the extent the law allows, we make no promises that it will meet your needs or run without interruption or error, and we are not liable for indirect or consequential loss, including lost sleep. Where liability cannot be excluded, our total liability to you is limited to the amount you paid for the app. Nothing in these terms limits rights that consumer law gives you and that cannot be waived, including rights under the Norwegian Consumer Purchases Act and, for consumers in the EU and EEA, your local consumer protection law.

9. Privacy

How the app handles data is described in the Privacy Policy, which is part of these terms.

10. Governing law

These terms are governed by Norwegian law. Disputes are resolved by the courts of Norway, unless you are a consumer with a right to bring proceedings in your own country. Consumers in the EU may also use the European Commission's online dispute resolution platform.

11. Changes to these terms

If we change these terms we will update the date at the top of this page. Continuing to use the app after a change means you accept the new terms. Changes will not take away a purchase you have already made.
