Common questions
Good things to know
Is there a subscription? No
No. £14.99 once and you're in for life. No renewals, no auto-charges, no surprise upgrades.
How does the 3-device limit work? It's easy
You can sign in on up to three devices — e.g. your phone, your tablet and your laptop, or use one for a partner/parents device. If you try to sign in on a fourth, you'll be sent a 'manage devices' email link so you can remove one of your active devices first.
Does it work offline? Yes
Yes — once you've signed in and the app loads the first time, it caches everything you need so you can use it without a connection. Handy for travel, the park, or any low/no-signal areas.
What devices does it run on? All
Any modern phone, tablet, or computer with a web browser — after purchase just save as an app to your home screen (mobile or tablet), or install it via your favourite browser as an app in Windows or Mac, it's easy. We're rolling out App Store and Play Store versions soon — your purchase will cover those too.
What if I want a refund? No problem
Email support@lumisteps.app within 30 days of purchase and we'll refund you, no hums and haws, no questions asked.
Who's behind Lumi Steps? We are
An independent project — no investors, no data sales, no ads. Just a small team trying to make the first 18 months feel a little less hectic, a bit more supported.
