Cancellation Lumen: Step-by-Step Guide

What is Lumen

Overview

Lumen is a health and wellness product that combines a handheld breath-analysis device with a subscription app to measure metabolism and guide nutrition and coaching.

The service uses breath sampling to estimate whether your body is burning fats or carbs and provides meal and coaching recommendations via the app.

How it’s delivered

The product is sold as a device bundled with a period of premium membership, or with ongoing subscription options for continued app features.

Hardware is purchased once in most packages, while premium access continues via a recurring subscription if you choose to keep it after the included period.

How to cancel Lumen

Check how you were billed

Identify whether your membership is billed directly by Lumen, through Apple App Store, or through Google Play.

Your cancellation route depends on which billing channel processed your subscription.

Step-by-step cancellation

• If billed through Apple App Store: cancel the subscription in your Apple ID > Subscriptions.
• If billed through Google Play: cancel via Google Play Store > Subscriptions on your Android device.
• If billed directly by Lumen: open the Lumen app or your Lumen account settings, go to Membership or Subscription, and select Cancel or Manage Subscription.
• If you cannot cancel via the app or store, contact Lumen support and provide your order details and account email. Refer to Lumen’s terms for contact points and policies: Lumen Terms of Use.
• Always keep confirmation emails or screenshots of cancellation actions until your billing cycle ends and your account reflects the change.

What happens when you cancel

Access and features

When you cancel, access to premium features generally continues until the end of the paid billing period you already paid for.

After that date, premium features are typically disabled unless you resubscribe.

Account and data

Your account and historical data usually remain associated with your email unless you request deletion per the provider’s privacy policy.

Check Lumen’s terms for details about data retention and requests related to account deletion: Lumen Terms of Use.

Will I get a refund?

General policy

Lumen’s standard terms state refunds are not automatic and depend on how and when you purchased the membership or device.

Subscriptions that renew are often non-refundable for the period already used, but specific circumstances and store policies may differ.

Exceptions and next steps

• If you purchased via Apple or Google, you may need to request a refund through their support channels according to their policies.
• If you believe you qualify for a refund (billing error, duplicate charge, or other valid reason), contact Lumen support with receipts and details; reference their terms: Lumen Terms of Use.
• Keep documentation of charges and communications; these are often required to evaluate refund requests.

Your consumer rights in Singapore

Key protections

In Singapore, consumers are protected against unfair practices and misrepresentation under local consumer protection laws.

If a product or service differs materially from what was promised, you can raise a dispute with local consumer authorities or seek remedies.

Practical steps locally

• Keep all receipts, order confirmations, and communications as evidence.
• If you cannot resolve a billing or refund dispute with Lumen, consider contacting the Consumers Association of Singapore (CASE) or pursuing small claims procedures.
• Check the seller’s published terms and the payment platform’s dispute/chargeback options if you paid by card.

Customer experiences

Positive feedback

Many users praise Lumen’s device concept and personalised nutrition guidance, noting improvements in daily tracking and awareness of metabolic state.

Device ease-of-use and app coaching are often mentioned as strengths in reviews.

Common complaints

Some users report issues with subscription management, unexpected renewals, or difficulties obtaining refunds depending on how the subscription was billed.

For community reviews and trends, see user feedback on review pages such as: Lumen on Trustpilot.

Documentation checklist

Before you contact support

• Order confirmation or receipt (showing date and amount).
• Account email used for Lumen app or website.
• Proof of payment method (card statement, App Store/Play Store receipt).
• Device serial number or order number if applicable.
• Screenshots of subscription settings or cancellation attempts.

What to include in a refund request

• Clear description of the issue and desired outcome (refund, cancellation confirmation, account deletion).
• Relevant dates: purchase date, renewal date, cancellation attempt date.
• Attach receipts and any supporting screenshots or correspondence.

Common mistakes

Missing the billing source

A frequent error is cancelling inside the Lumen app when the subscription is billed through Apple or Google; this does not stop store-managed renewals.

Always confirm the billing source in your account or receipt before cancelling.

Waiting too late or no confirmation

Many users assume cancellation is instant; if you cancel close to renewal you may still be charged for the next cycle.

Always save a cancellation confirmation and check the billing statement the next cycle to ensure the charge stopped.
