Terms of Use

Last updated: 19 October 2026

The short version: Lumena is a practice tool, not a speech therapist. It runs on a subscription that renews automatically until you cancel, and you cancel it yourself in your Apple Account settings at any time.

Agreement

These terms govern your use of the Lumena iOS app. By downloading or using the app, you agree to them. If you do not agree, please do not use the app.

Lumena is also licensed to you under Apple's Licensed Application End User License Agreement. Where these terms and Apple's standard EULA conflict, these terms apply to the extent permitted.

Your licence

We grant you a personal, non-transferable, non-exclusive licence to use Lumena on Apple devices that you own or control, in line with the App Store Terms of Service. You may not copy, redistribute, reverse-engineer or resell the app, or attempt to extract the speech models it ships with.

Subscriptions and billing

Lumena requires a subscription, Lumena Pro, to use its practice, review, insights and coaching features. The following terms apply:

Plans. Lumena Pro is offered as a monthly plan and an annual plan. The price, billing period and any free trial are shown in the app before you confirm, in your local currency.
Free trial. New subscribers are offered a 7-day free trial. If you do not cancel before the trial ends, the subscription begins and your Apple Account is charged. Any unused portion of a free trial is forfeited if you buy a subscription before the trial ends.
Auto-renewal. Subscriptions renew automatically unless cancelled. Your Apple Account is charged for renewal within 24 hours before the end of the current period, at the then-current price for your plan.
Managing and cancelling. You manage and cancel your subscription in your Apple Account settings, or from Settings inside the app. Cancelling stops the next renewal; it does not retroactively refund the current period.
Payment. All payments are processed by Apple, not by us. We never see or hold your payment details.
Refunds. Refunds are handled by Apple under the App Store Terms of Service. We cannot issue them directly, though we are happy to help you raise a request.
Price changes. If we change the price of a plan, Apple will notify you and ask for your consent before the new price takes effect, as required by the App Store.

What Lumena is not

Lumena is a practice and self-improvement tool. It is not a medical device, and it does not provide speech therapy, diagnosis or treatment. Its metrics and coaching are not clinical assessments. If you have concerns about your speech, voice or hearing — including stammering, a voice disorder, or pain when speaking — please speak to a qualified professional.

AI-generated coaching

Lumena's coaching features generate written feedback using an on-device language model. Generated feedback can be incomplete, mistaken or poorly judged, and it is offered as a prompt for your own thinking rather than as authoritative advice. You remain responsible for anything you say or do based on it. If a piece of feedback seems wrong or inappropriate, please tell us through our support page so we can improve it.

Acceptable use

Please use Lumena only for lawful purposes. Do not use it to record people without their knowledge where that is unlawful where you are, and do not attempt to interfere with the app's operation or security.

Your content

Your recordings, transcripts and analysis stay on your device. We do not receive them, so we claim no rights over them and cannot access, recover or delete them for you. You are responsible for keeping your own backups — see our Privacy Policy for detail.

Availability

Some features, including AI coaching, depend on Apple Intelligence and on device capabilities outside our control. We may change, suspend or discontinue features over time. If we discontinue a material part of a paid subscription, you may cancel and seek a refund through Apple.

Disclaimer and liability

Lumena is provided "as is", without warranties of any kind to the fullest extent permitted by law. We do not warrant that it will be uninterrupted, error-free, or that its measurements will be accurate for every voice, accent or recording environment.

To the fullest extent permitted by law, we are not liable for indirect, incidental or consequential loss arising from your use of the app. Nothing in these terms limits liability that cannot lawfully be limited, including for death or personal injury caused by negligence, or for fraud. If you are a consumer, your statutory rights are unaffected.

Changes to these terms

We may update these terms as the app develops. If we make material changes, we will update this page and revise the date above. Continuing to use the app after a change means you accept the updated terms.

Governing law

These terms are governed by the laws of Ireland. If you are a consumer resident elsewhere in the EU, you keep the benefit of any mandatory consumer protections of your country of residence.
