Cancellation Lumo: Easy Method
What is Lumo
Overview
Lumo is a subscription-based wellness platform offering personalized coaching, fitness plans, and guided content delivered through apps and web services.
It provides free and paid tiers, including an add-on called Lumo Plus for additional features such as synced projects and premium content.
How it is delivered
Lumo subscriptions can be purchased directly via Proton's web dashboard or through mobile app stores (Google Play on Android and the App Store on iOS).
Purchase channel affects how you manage and cancel the subscription and how refunds are handled.
How to cancel Lumo
Cancel via Proton web (direct purchase)
- Sign into your Proton account dashboard.
- Navigate to Billing or Subscriptions.
- Edit the Lumo or Lumo Plus add-on and choose Cancel.
- Confirm the cancellation to complete the process.
Cancel via mobile stores (Android / iOS)
- Google Play (Android): Open Google Play Store → Payments & subscriptions → Subscriptions → find Lumo or Lumo Plus → select Cancel subscription → confirm.
- App Store (iOS): Open iOS Settings → tap your name → Subscriptions → select Lumo or Lumo Plus → tap Cancel Subscription → confirm.
- Note: Store-managed subscriptions cannot be cancelled from Proton's web UI and must be handled in the respective store.
What happens when you cancel
Access and renewal
After cancelling, your access to Lumo continues until the end of the current billing period.
No new renewals will be charged after the cancellation takes effect for that billing period.
Data and account status
Cancellation typically removes future billing but may not delete account data; check Proton's account or privacy settings to manage stored content.
If you purchased via an app store, account content and access rules follow Proton and store policies; confirm in your account dashboard.
Will I get a refund?
Direct purchases (Proton web or app)
If you subscribed directly via Proton, you may cancel and request a prorated refund within 30 days of the initial purchase.
Refunds are processed within 30 days of an approved request and are available only once per user; both cancellation and refund request must be within the 30-day window.
Store purchases and exceptions
Purchases made through Google Play or the App Store are subject to those stores' refund rules and are not covered by Proton's direct refund process.
Beyond the 30-day period, no refunds are generally available unless Proton decides otherwise at its discretion. Proton does not state a 14-day automatic cooling-off right.
Lumo plans and pricing
Where to check pricing
Pricing and plan details can change; always check the official Lumo or Proton website or the relevant app store page for current rates.
This guide does not list prices - refer to the product pages inside the Proton dashboard or the app stores for up-to-date information.
Billing cadence
Plans typically offer recurring billing options (e.g., monthly or annual) depending on the purchase channel and the selected plan.
Confirm the billing period and renewal date before cancelling to understand prorated refunds and remaining access.
Your consumer rights in Singapore
Relevant protections
Singapore consumer protection laws such as the Consumer Protection (Fair Trading) Act provide rights for defective products or services not rendered as promised.
For digital services, statutory cooling-off rights may not automatically apply unless offered by the provider.
Practical steps for Singapore consumers
Keep proof of purchase and cancellation records. If issues remain unresolved, you may escalate to the Consumers Association of Singapore (CASE).
Store-based purchases rely on Google Play or App Store policies; these platforms have their own processes and limited protections under their terms.
Customer experiences
Positive feedback
- Users praise Lumo's privacy focus and the encrypted "Projects" feature for organized, private conversation spaces across devices.
- Some users report noticeable improvements over time, describing the service as increasingly functional and helpful for structured tasks.
Negative feedback
- Early-release bugs reported: broken support buttons, app crashes on Android, unsupported browser errors on iOS, and subscription launch issues.
- Complaints about hallucinations, outdated knowledge cut-off (2024), web-search accuracy, and confusing subscription management were common.
Documentation checklist
Essential items to keep
- Proof of purchase or receipt (email or app store transaction ID).
- Subscription ID or plan name (Lumo, Lumo Plus).
- Dates of purchase, billing period, and cancellation request.
Support evidence
- Screenshots of subscription pages, error messages, or failed cancellation attempts.
- Copies of messages exchanged with Proton support or app store support.
Common mistakes
Attempting wrong cancellation channel
Many users try to cancel store-managed subscriptions from the Proton web dashboard. Store purchases must be cancelled in Google Play or Apple Subscriptions.
Try the store's subscription settings first if you purchased through an app store.
Missing documentation or timing
Not keeping receipts, transaction IDs, or screenshots makes refunds and disputes harder to resolve.
Missing the 30-day refund window for direct purchases is a frequent issue - act promptly if you seek a prorated refund.
