Terms
The agreement between you and Lumi Steps when you buy access, written to be readable.
Last updated: 18 October 2026
1. About these terms
These terms apply between you (the customer) and the developer of Lumi Steps when you purchase access to the Lumi Steps app. By completing your purchase, you agree to these terms. If you don't agree, please don't complete the purchase.
If you bought via the App Store, Apple's Licensed Application End User License Agreement (the "Standard EULA") also applies to your use of the app, see section 6.
If you bought via the Google Play Store, Google's terms of service for the Play Store also apply to your purchase and account.
2. Who you're buying from
8stacks8, a small independent studio run as a sole trader in the United Kingdom
Suite 1007, 22 Notting Hill Gate, London W11 3JE, United Kingdom
3. What you're buying
Lumi Steps for iOS is a native app available from the Apple App Store. It helps parents and caregivers track their baby's milestones, soothe fussy moments, and support healthy development from newborn through 18 months.
Lumi Steps for Android is a native app available from the Google Play Store. It helps parents and caregivers track their baby's milestones, soothe fussy moments, and support healthy development from newborn through 18 months.
You're buying lifetime access for a one-time fee, no subscription, no auto-renewals, no further charges. "Lifetime" means: for as long as Lumi Steps continues to operate as a service. We've designed this to last and we have no plans to discontinue. If we ever did need to wind the service down, we'd give you reasonable notice (at least 90 days) and offer a pro-rata goodwill refund where appropriate.
4. Price and payment
- The price is £11.99 GBP, one-time, purchased via Apple's In-App Purchase. Apple sets the displayed price in your local currency and collects any applicable VAT or sales tax on our behalf.
- Apple is the merchant of record. Your card details, billing address, and Apple ID are processed by Apple, they never reach us.
- Access is tied to your Apple ID. No sign-in email is needed; reinstalling on any device signed in to the same Apple ID restores access via the Restore Purchases button.
- If Apple declines the payment, no charge is made and no access is granted.
- The price is £11.99 GBP (UK), one-time, purchased via Google Play Billing. Google sets the displayed price in your local currency and collects any applicable VAT or sales tax on our behalf.
- Google is the merchant of record. Your card details and Google account billing data are processed by Google, they never reach us.

5. Refunds & cooling-off
App Store purchases are handled by Apple, so refunds are too:
- Refund requests go through Apple, not us. Visit reportaproblem.apple.com, or on your iPhone / iPad: Settings → [your name] → Media & Purchases → Account → Purchase History → "Report a Problem". You can also contact Apple Support directly. Apple's refund policy applies, we cannot issue App Store refunds ourselves.
- If Apple grants a refund, your Lumi Steps entitlement automatically revokes via RevenueCat within minutes.
- Statutory rights are unaffected. UK consumer rights, including the 14-day cooling-off period for digital content under the Consumer Contracts Regulations 2013, apply directly between you and Apple as the merchant.
- If Apple declines a request you believe is valid, contact us at support@lumisteps.app and we'll do our best to help, but the decision sits with Apple.
Google Play purchases are handled by Google, so refunds are too:
- Refund requests go through Google, not us. Open the Google Play Store app → tap your profile icon → Payments & subscriptions → Budget & history → tap the Lumi Steps order → Request a refund. You can also visit play.google.com/store/account/orderhistory or contact Google Play Support. Google's refund policy applies, we cannot issue Play Store refunds ourselves.

6. Your licence to use Lumi Steps
When you purchase access via the App Store, your use of Lumi Steps is governed by Apple's Licensed Application End User License Agreement (Apple's "Standard EULA"), which auto-applies to App Store purchases. The clauses below apply between you and us in addition to Apple's EULA, and where they don't conflict with it.
We grant you a personal, non-exclusive, non-transferable licence to use Lumi Steps for personal (non-commercial) use.
You may:
- Use Lumi Steps on any iPhone, iPad, or Apple Silicon Mac signed in to your Apple ID.
- Share your purchase with up to 6 family members through Apple Family Sharing, each on their own Apple ID and devices. This is Apple's standard entitlement.
- Reinstall and restore your purchase via the Restore Purchases button in the app at any time.
- Continue to use the app for as long as the service is available, with no further charges.
You may not:
- Resell, redistribute, sub-license, or share your Apple ID credentials with others outside your immediate family.
- Reverse-engineer, decompile, or extract the source code or content of the app (subject to applicable mandatory rights under law).
- Use Lumi Steps to break any law, or in any way that interferes with our ability to provide the service to others.
Apple's role. Apple is not a party to this agreement between you and us; Apple's role is limited to providing the App Store and processing your purchase under Apple's own terms. Apple has no obligation to provide maintenance, support, or warranty service for Lumi Steps, that responsibility is ours (and our service provider RevenueCat's). If Lumi Steps fails to conform to any applicable warranty, you may notify Apple, and Apple may refund the purchase price under the App Store policy. Apple has no other liability with respect to Lumi Steps.
When you purchase access via the Google Play Store, your use of Lumi Steps is also subject to Google's terms of service and the Play Store's standard buyer protections. The clauses below apply between you and us in addition to those.
We grant you a personal, non-exclusive, non-transferable licence to use Lumi Steps for personal (non-commercial) use.
You may:
- Use Lumi Steps on any Android phone, tablet, or Chromebook signed in to your Google account.
- Reinstall and restore your purchase via the Restore Purchases button in the app at any time.
- Continue to use the app for as long as the service is available, with no further charges.
You may not:
- Resell, redistribute, sub-license, or share your Google account credentials with others outside your immediate household.
- Reverse-engineer, decompile, or extract the source code or content of the app (subject to applicable mandatory rights under law).
- Use Lumi Steps to break any law, or in any way that interferes with our ability to provide the service to others.
Note: Google Play does not currently support sharing in-app purchases across different Google accounts (Play Family Library covers app installs but not IAPs). One purchase covers every device signed into your Google account; other family members on their own accounts would need their own purchase.
7. Updates and future versions
We update Lumi Steps from time to time, bug fixes, new features, and improvements. Updates are included in your purchase at no extra cost.
iOS updates are delivered through the App Store at no extra cost. Your purchase covers Lumi Steps on iOS only; the web (lumisteps.app) and Android versions are sold separately on their own platforms.
Android updates are delivered through the Google Play Store at no extra cost. Your purchase covers Lumi Steps on Android only; the web (lumisteps.app) and iOS versions are sold separately on their own platforms.
8. Medical disclaimer
Lumi Steps provides general guidance and content informed by published material from the American Academy of Pediatrics (AAP) and the Centers for Disease Control (CDC). It is not a medical device and is not a substitute for professional medical advice. If you have any concerns about your baby's development, health, or wellbeing, please consult a qualified healthcare professional.
9. Service availability and "as-is" terms
We try to keep the service running smoothly but we can't guarantee 100% uptime.
Occasional planned maintenance or third-party outages (e.g. Apple's App Store servers, RevenueCat) may briefly interrupt verification of your purchase. The app itself runs from your device, so most interruptions only affect first-time purchase or restore. We don't owe a refund for short interruptions; refund requests for App Store purchases go through Apple as described in section 5.

We don't owe a refund for short interruptions; refund requests for Play Store purchases go through Google as described in section 5.
Except where we owe you specific things under UK consumer law (see section 10), Lumi Steps is provided "as is" and "as available", without further warranties of any kind.
10. Our liability to you
Nothing in these terms limits or excludes our liability for:
- death or personal injury caused by our negligence;
- fraud or fraudulent misrepresentation;
- breach of your statutory rights under the Consumer Rights Act 2015;
- any other liability that cannot be excluded under English law.
Subject to those, our total liability to you arising out of or in connection with Lumi Steps will not exceed the amount you paid us (i.e. £11.99). We won't be liable for indirect or consequential losses, lost profits, or losses arising from circumstances beyond our reasonable control.
11. If we end your access
We may terminate your access immediately if you materially breach these terms (for example: trying to share access at scale, abusing the refund policy in bad faith, or attempting to bypass payment). In all but the clearest cases of abuse, we'll write to you first via your registered email so you can respond.
If we terminate without good cause, we'll refund the unused portion of your purchase pro-rata.
12. You can stop anytime
You can stop using Lumi Steps anytime, there's nothing to cancel and nothing to pay.
Within Apple's refund window you can request a refund through Apple (section 5). After that, simply uninstalling the app from your devices is enough, there's no account on our side to close. (We don't hold an email or device list for App Store buyers; see the privacy policy.)
Within Google's refund window you can request a refund through Google (section 5). After that, simply uninstalling the app from your devices is enough, there's no account on our side to close. (We don't hold an email or device list for Play Store buyers; see the privacy policy.)
13. Changes to these terms
We may update these terms from time to time, for example to reflect changes in the law or new features. The "Last updated" date at the top reflects the most recent change. If the change materially reduces your rights, we'll flag it on this page and in the app, since we hold no email addresses.
14. Governing law and disputes
These terms are governed by the law of England and Wales. Any dispute that can't be resolved by agreement will be subject to the non-exclusive jurisdiction of the courts of England and Wales.
If you have a complaint, please email support@lumisteps.app first, we'll do our best to resolve it. Nothing in these terms affects your statutory rights as a consumer.
