Counted, not claimed.
What Lumi guarantees — spelled out for owners, their accountants, and everyone who books. Each one is part of how the product works, not a promise.
Eight things that are always true.
No dark patterns, as policy: no fake urgency, no hidden fees, no manipulative defaults, no marketing disguised as a reminder. Trust is the product.
Every business is verified.
A studio is checked before it can take a single booking on Lumi. No unverified listings, ever.
Reviews are earned, not imported.
Only people who actually showed up can leave a review — and you rate the person who did your appointment, not just the place.
A double-booking is physically impossible.
The calendar itself refuses a second booking in the same slot — the instant a booking lands, the slot is blocked. Two people cannot book the same chair.
Your data lives in the EU.
Frankfurt, GDPR from day one: export your data anytime, delete your account in one click, gone within 30 days. Strictly-necessary cookies only; no ads, no cross-site tracking, no data sales.
One studio can never see another's data.
The walls between studios are part of the foundation — and we test them constantly.
Anonymous means anonymous.
Comparisons with similar businesses are opt-in and always anonymous — never fewer than five in the group. Competitors are never named, and neither are you.
Lumi never holds your money.
Where card payments are available, Stripe handles deposits — payouts land in your own account daily, no cut of your bookings. In Serbia today customers pay at the appointment.
Two languages, one voice.
Serbian and English everywhere — customer app, owner dashboard, emails, WhatsApp — written naturally in both, not machine-translated.
Where it's written down.
The full versions live on three pages — in Serbian and English.
