Cancellation Lumen: Easy Method
What is Lumen
Overview
Lumen is a consumer device and subscription-based app that measures metabolism and provides personalised nutrition and metabolic guidance.
The service combines a handheld breath device with an app membership to deliver daily metabolic insights and plans.
Subscription model
Lumen subscriptions can be sold bundled with the device (multi‑month plans) or as ongoing individual or duo memberships.
Billing and subscription management depend on where you purchased: Apple App Store, Google Play, or directly via the Lumen website.
How to cancel Lumen
Cancel via App Store (iOS)
- Open your iPhone or iPad Settings and tap your Apple ID at the top.
- Choose Subscriptions, find the Lumen subscription and tap Cancel Subscription.
- Note: Deleting the app does not cancel your subscription; you must cancel through Apple ID settings.
Cancel via Google Play Store (Android)
- Open the Google Play Store app and tap your profile icon.
- Go to Payments & Subscriptions > Subscriptions, select Lumen and tap Cancel subscription.
- Note: Deleting the app does not cancel the subscription; cancel through Google Play to stop renewals.
Cancel directly on the Web (lumen.me purchases)
- Open the Lumen app or account settings on the web and go to subscription settings to cancel.
- If you cannot cancel in-app, email support@lumen.me at least 1 day before the next renewal to request cancellation.
- Cancellation requests for web purchases generally take effect at the end of the current paid period.
What happens when you cancel
Access and membership
When you cancel, you typically retain access to the Lumen app features until the end of the current paid billing period.
Access does not usually end immediately unless specified by the store or Lumen terms.
Auto‑renewal and billing
Cancellations stop future auto‑renewals; you will not be billed after the current paid period ends if cancellation is successful.
For subscriptions billed through Apple or Google, those stores control renewals and refunds per their policies.
Data and account
Your Lumen app data typically remains in your account unless you request deletion under Lumen’s policies or terms of use.
Check Lumen’s terms for data retention or contact support if you want your account and data removed.
Will I get a refund?
Web purchases and device refunds
Web subscriptions are generally non‑refundable, per Lumen’s stated policy for online purchases.
Device returns may be possible if the device is unopened within 30 days of purchase; opened-device returns are conditional.
App Store and Google Play purchases
Purchases made through the Apple App Store or Google Play are subject to those stores’ refund policies; Lumen does not control those refunds.
If you want a refund for a store purchase, request it through Apple or Google Play support.
Exceptions and timing
- Device returns: typically a 30‑day window for unopened items when purchased on the web.
- Subscription cancellations normally take effect at the end of the paid period; refunds are not routine for partial periods.
- If you believe a charge was unauthorized or auto‑renewal was not properly disclosed, keep documentation to contest the charge.

Your consumer rights in India
Cooling‑off and returns
Under Indian consumer protection laws, online consumers are generally entitled to a 7‑day "cooling‑off" period for goods purchased online, unless specifically exempted.
This cooling‑off right may apply to unopened device returns; check Lumen’s policy and provide proof of purchase.
Accuracy, defects and auto‑renewal
Consumers have rights if the product is defective or not as described, which can entitle them to repair, replacement, or refund depending on the situation.
Auto‑renewal must be clearly disclosed and consented to; unexpected charges can be contested under the Consumer Protection Act, 2019.
How to exercise rights
- Keep order confirmations, transaction receipts and screenshots of subscription pages and disclosures.
- Contact Lumen support first; escalate to payment provider or app store if unresolved.
- If needed, consider filing a consumer complaint with local consumer protection authorities in India.
Customer experiences
Positive feedback
Many users praise Lumen for raising metabolic awareness, offering actionable insights and helping with food choices and weight management.
Support is often commended as responsive and helpful in several reviews.
Negative feedback
Common negatives include unexpected auto‑renewal charges, concerns about refunds for opened devices, and inconsistent readings for some users.
Other complaints cover software integration limits, hardware issues (charging/battery), and occasional slow support for device replacement.
Takeaway
- Weigh the potential benefits against the mixed hardware/software reports before purchasing.
- Keep clear records and understand store vs web purchase rules to avoid renewal surprises.
Documentation checklist
Essential items to have
- Order number and purchase receipt (email or invoice).
- Account email used with Lumen and device serial number (if applicable).
- Payment proof (card statement, transaction ID) showing the charge.
Helpful supporting materials
- Screenshots of subscription pages, app billing screenshots, or auto‑renewal disclosures.
- Correspondence with Lumen support and any case/ticket numbers.
Common mistakes
Deleting the app instead of cancelling
Many users assume deleting the app cancels the subscription. It does not; you must cancel via Apple ID, Google Play, or Lumen account depending on purchase method.
Waiting too long to request a refund
Expecting a refund after opening a device or after the 30‑day window can lead to disappointment; check return windows and keep packaging sealed if you may return.
Not checking which platform billed you
Refund and cancellation steps differ by platform. If billed by Apple or Google, contact those stores for refund requests instead of emailing Lumen support alone.
