Room Flow schedules your rooms and equipment directly in your own Zimbra/CalDAV calendars and on your machines. Your bookings never pass through our servers: we can't read them and we can't sell them — by design.

The problem
Booking a meeting room shouldn't mean handing your agenda to a third party.
Double bookings are expensive. Shared spreadsheets, sticky notes on doors, “is the room free?” emails: every scheduling conflict interrupts two teams at once.
Typical cloud tools centralize everything with the vendor. Who books what, with whom, how often — internal information that leaves your organization for no good reason.
Many tools stop when the network stops. An internet outage shouldn't block booking a room that's ten meters away.
The solution
A clear schedule — and data that never leaves your organization.
One schedule for rooms and equipment. Everyone sees what's free and books in a few clicks, recurring slots included.
Your bookings live in your calendars. Room Flow writes to your Zimbra/CalDAV calendars and to your machines. The vendor portal only manages the license — never your schedules.
Offline mode is built in. The application verifies your license locally using a signed certificate: no permanent connection to our servers is required to get work done.
Features
Everything you need to schedule. Nothing that spies on you.
A deliberately minimal interface: your teams see what's free, book it, and get on with their day.
Room scheduling
All your rooms, one single grid.
All your rooms at a glance: capacity, floor, availability. A free slot can be booked straight from the grid.
TYPICAL WEEK
free busy
Equipment scheduling
Gear included.
Projectors, vehicles, video-conferencing gear: equipment is booked exactly like rooms, with the same schedule and the same rules.

Recurrence
Define it once, placed everywhere.
Weekly meeting, monthly board: define the recurrence once and Room Flow places every slot and flags conflicts.
Seats & anti-sharing
Named accounts, under your control.
Each organization manages its own admin and user seats. Each account activates a defined number of devices; the admin can see active devices and revoke any of them at any time.
Zimbra / CalDAV integration
Your calendars, no duplication.
Your bookings are written to calendars you already own. No duplication, no data silo at a third-party vendor.

Offline & signed license
Network goes down? Your bookings don't.
Your license is a signed certificate stored on your machine. The application verifies it locally: it works without a permanent connection to our servers.

Privacy & data ownership
Our number-one argument fits in one sentence: we're not interested in your data.
Every promise in this section matches what the software actually does — not a marketing intention.
01
Data minimization, literally
The portal collects only what your account and license strictly require: your organization's name, the email address and (hashed) password of each account, and — for each device activation — the account email and a device fingerprint. The exhaustive list, item by item, is in our privacy policy. No superfluous fields, no data collected “just in case”.
02
Your bookings live in YOUR calendars
Rooms, equipment, attendees, recurrences: everything is written to your Zimbra/CalDAV calendars and your machines. None of it is centralized with us — we couldn't show you your schedules even if you asked.
03
You're the owner, not a tenant
Your data belongs to you and stays with you. From your account area, you can export the data the portal holds (JSON format) and delete your account or organization at any time, without going through support.
04
Hosted in Switzerland / the European Union
The portal (website, accounts, licenses) is hosted in Switzerland or the EU, under the GDPR and the Swiss nFADP. Your schedules stay on your own infrastructure regardless.
05
No data resale, no ad profiling
We don't sell data, we don't rent it, and we build no advertising profiles. Our business model is the subscription — you pay for the software; you are not the product.
06
Privacy by design & by default
Privacy isn't a setting you switch on: it's the architecture. Minimal data by default, zero third-party resources loaded on this site, and audience measurement only after your explicit consent.

FAQ
The questions we get asked. And the ones we wish we were.
In short: your organization's name, the email address and (hashed) password of each account, license and subscription data, and — for each device activation — the account email and a device fingerprint (used solely for anti-sharing). The exhaustive list, with purposes and retention periods, is in our privacy policy. Your bookings, attendees and schedules are not collected: they stay in your calendars and on your machines.
In your own Zimbra/CalDAV calendars and on your workstations. The Room Flow portal stores no bookings at all: it only manages your account, your license and your device activations.
Yes — both, at any time, from your account area. The export produces a JSON file of the data the portal holds about your organization. Deleting your account or organization erases that data; your calendars stay with you and are unaffected.
Your license is a cryptographically signed certificate file, downloadable from your account area. The application verifies it locally, without calling our servers — so it works without a permanent internet connection.
Each account can activate a number of devices defined by your plan. On activation, the portal records the account email and a device fingerprint. Your admin can see the list of active devices and revoke any device at any time — for example when replacing a workstation.
From your account area, in a few clicks, with no support ticket and no justification required. The subscription stops at the end of the period you've already paid for. You can export your data before, during and after cancellation.
Nothing automatic: we don't ask for a credit card at signup, so there's no surprise charge. After 30 days, you pick a plan to continue — or you don't, and your account simply stays inactive until deletion.
No. Room Flow works with Zimbra or with any CalDAV-compatible calendar server ([[À COMPLÉTER : liste des serveurs CalDAV testés]]).
In Switzerland or the European Union ([[À COMPLÉTER : hébergeur et localisation exacte]]), under the GDPR and the Swiss nFADP. Reminder: the portal only holds account and license data — not your schedules.
