Terms of Use

Effective 17 October 2026

These terms cover your use of the Earluma app for iPhone and the earluma.com website. Earluma is provided by Rafael Lopes, an individual developer based in Portugal ("I", "me"). Contact: support@earluma.com.

1. Licence (EULA)

Earluma is licensed to you under Apple's Licensed Application End User License Agreement (the "Standard EULA"). These terms add to the Standard EULA. If the two conflict, the Standard EULA applies, except where these terms give you more rights.

2. What Earluma does

Earluma appears as an audio output on iOS 27 or later. Audio you send to it is corrected on your iPhone for the headphones you choose and then played on those headphones. Corrections are computed from published headphone measurements made by third parties. Results depend on your headphones, how they fit, your ears and your hearing, so Earluma cannot promise a specific sound. Earluma is not a medical device and does not test, diagnose or treat hearing.

3. Listen at safe levels

Corrections and features like loudness compensation and psychoacoustic bass change how loud music seems. Start at a low volume and turn it up gradually. Long listening at high volume can damage your hearing.

4. Purchases

• Headphone profiles are one-time purchases that unlock the measured profile for one headphone model. The price depends on the retail price of that headphone (from €0.99 to €7.99, or the equivalent in your App Store currency).
• Earluma Lifetime is a one-time purchase (€39.99) that unlocks everything included in All Access, with no time limit.
• Profile preview. Each measured profile can be heard free once, for 10 minutes of listening. After that, Earluma returns to the generic correction for that profile until it is unlocked.
• The generic correction for any headphones is free.

All purchases are made through Apple's App Store and are tied to your Apple ID. Restore them on a new device with "Restore purchases" in the app.

5. Earluma All Access subscription

• Earluma All Access is an auto-renewable subscription, billed yearly at €14.99 (or the equivalent in your App Store currency). It unlocks every measured profile, including profiles added later, saving your taste result and ear balance, and the virtual room.
• New subscribers may get a 7-day free trial. If you do not cancel at least 24 hours before the trial ends, the yearly subscription starts and you are charged.
• Payment is charged to your Apple ID when you confirm the purchase, or when the free trial ends.
• The subscription renews automatically for another year unless you turn off auto-renew at least 24 hours before the end of the current period. Your account is charged for renewal within 24 hours before the end of the current period.
• Manage or cancel in Settings > your name > Subscriptions, or in the App Store account settings. Cancelling stops the next renewal; access continues until the end of the period you paid for.
• If a price changes, Apple will notify you in advance as required by its rules and the law.

6. Refunds

Refunds are handled by Apple. Request one at reportaproblem.apple.com. If Apple refunds a purchase, the related unlock is removed. Nothing here limits your rights as a consumer under the law of your country.

7. Catalogue and availability

The list of measured headphones can change. New profiles are added, and a profile may be updated when better measurements appear. If a profile you bought has to be removed, I will try to keep it working on your device or offer a reasonable alternative. Earluma depends on features of iOS 27. If Apple changes or removes them, some functions may stop working.

8. Fair use

Don't reverse engineer the service beyond what the law allows, don't try to get paid content without paying for it, and don't overload or attack the server.

9. Trademarks and open-source software

Headphone brand and model names are trademarks of their owners. Earluma is not affiliated with, endorsed by or sponsored by any headphone maker. Spotify, Apple Music and other app names belong to their owners.

Open-source software

Earluma includes the following open-source software, used under its licence: the EffectDeck audio driver (MIT), mEDIFIER (MIT), the MIT KEMAR HRTF, bs2b and the Sora typeface (SIL Open Font License).

10. Liability

Earluma is provided as is, within the limits of the Standard EULA and applicable law. I am not liable for indirect losses. Nothing in these terms limits liability that cannot be limited by law, including for death or personal injury caused by negligence, fraud, or your statutory rights as a consumer.

11. Privacy

See the privacy policy.

12. Changes and law

I may update these terms. The current version is always on this page, with its date. These terms are governed by Portuguese law, without depriving you of the protection of the mandatory rules of the country where you live. Consumers in the EU can also use the alternative dispute resolution bodies available in their country.
