We each do our own job

For years, we've done one thing: appointment infrastructure. No marketplace. No visibility play. No data collection. We are your invisible supplier, and that's by choice.

What we do

  • White-label appointment booking
  • Scheduled email & SMS reminders
  • Complete, documented REST API
  • Embeddable widget, one line of code
  • Automatic data deletion
  • Dedicated IP, SPF/DKIM/DMARC configured

What we don't do

  • Practitioner marketplace
  • Data collection or resale
  • Store data beyond what's necessary
  • Open freemium for everyone
  • Self-serve without onboarding
  • Chase visibility

Essential features, no bloat

Fair pricing, must-have features. We do one thing, and we do it well.

📅

Appointment booking

Slots, booking, cancellation, rescheduling. Booking page in your brand colors.

🔔

Automated reminders

Email and SMS. D-2, D-1, H-2… configure your sequences. Sent to the second.

🏷️

White label

Logo, colors, sending domain. Your clients only see you. We stay invisible.

</>

REST API

Integrate in hours. API key auth. Webhooks for delivery tracking.

📊

Webhooks & analytics

Sent, delivered, bounced, opened. No-show rates. Everything flows back to your tool.

🧩

Embeddable widget

One line of code. The widget integrates into your site or app. Responsive, customizable.

Integrate in 3 steps

1

Onboarding

We create your partner account, configure your sending domain and templates.

2

Integration

Call our API from your app. POST /bookings, POST /schedules, that's it.

3

Production

Reminders go out. Data gets deleted. Your clients don't even know we exist.

GDPR by design,
not by compliance

We only store the strict minimum: a name, an email or phone number, an appointment date. A few days after the appointment, everything is automatically deleted. No history. No profiles. Nothing to steal, nothing to leak.

Want to collect data through bookings? That's your responsibility, your consent to obtain, your storage to manage. Don't count on us. That's precisely why your reminders land in the inbox, not in spam.

Appointment created Data stored (name, contact, date)
Reminders sent D-2, D-1, H-2… per configuration
Appointment date passed Grace period (a few days)
Automatic deletion No trace. Zero residual data.

Who are our clients?

We could do like everyone else and display nice logos here.
But would you really want yours to be among them?
We are an invisible supplier. We respect our values and our clients.

Want a demo?

It's right here. We use our own tools.

Book a slot to talk about your project. 30 minutes, no commitment, video call or phone.

No email displayed here. We don't want to be scraped — just like our clients. Do as we do: don't put it out there if you don't want useless spam. Ask your clients to book an appointment instead.
