Privacy policy.
We keep this simple: we only collect what we need, we never sell your data, and you stay in control of it.
Last updated: 28 October 2026
1. Who is responsible for your data
The controller of your personal data is Celya Technologies SRL (trading as Celya), company number 1042.115.837, whose registered office is stated in the legal notice. You can reach us at sales@celya.be for anything related to your data.
2. What data we collect
We only collect personal data you choose to give us, and the minimum technical data needed to run the site.
- Contact & booking form: your name, email address, company name and the content of your message.
- Email: if you email us directly, we keep your message and address to reply.
- Technical data: standard server log data (e.g. IP address, browser type) processed by our host to deliver and secure the site.
We do not use advertising trackers, and we do not buy or sell personal data.
3. Why we use it, and the legal basis
- To answer you and prepare a proposal, based on your request and our pre-contractual / legitimate interest (Art. 6(1)(b) and (f) GDPR).
- To run and secure the website, based on our legitimate interest in a working, safe site (Art. 6(1)(f) GDPR).
- To meet legal obligations, e.g. accounting, where a contract follows (Art. 6(1)(c) GDPR).
4. How long we keep it
We keep enquiry data for as long as needed to handle your request and, if you become a client, for the duration of our relationship plus the legal retention periods (e.g. 7 years for accounting records in Belgium). Otherwise we delete or anonymise it within 24 months.
5. Who can access it
Your data is handled by Celya Technologies SRL and by a small number of trusted processors acting on our instructions, such as our email provider (Zoho Mail) and our website hosting provider. We do not transfer your data outside the EEA unless an adequate safeguard (e.g. EU Standard Contractual Clauses) is in place.
6. Your rights
Under the GDPR you can, at any time, request: access to your data; correction; erasure; restriction; objection to processing; and data portability. To exercise any of these, email sales@celya.be. You also have the right to lodge a complaint with the Belgian Data Protection Authority (Autorité de protection des données / Gegevensbeschermingsautoriteit), dataprotectionauthority.be.
7. Security
We apply reasonable technical and organisational measures to protect your data against loss, misuse and unauthorised access. No method is 100% secure, but we work to keep risk low.
8. Google Calendar
If you connect your Google Calendar account to Celya (Settings → Integrations), Celya Technologies SRL accesses some of your calendar data through Google APIs. Connecting is optional, and you can remove it at any time.
What we read, and why
| Calendar data | What we do with it |
|---|---|
| Start and end time of each event | Your AI receptionist never offers that slot to a caller. |
| Event title | Shown in your Celya console, to the users of your account (and to the Celya team when it assists you). Nowhere else. |
| Status (confirmed, cancelled, marked “free”, invitation declined) | Knowing whether the slot is really taken. |
| Description, location, attendee list | Never kept. |
What we write
- Celya creates a separate calendar in your Google account, “Celya — Réservations”.
- We add each appointment booked by Celya to it (the person’s name, date and time, and a link to the booking in your console), update it if it moves, and delete it if it is cancelled in Celya.
- Celya cannot change or delete events in your other calendars: the permission we request from Google does not allow it.
Where this data goes
- It is stored in the European Union. Your Google access tokens are encrypted, and access to your calendar data is restricted to your account.
- Our hosting providers process it on our behalf: Supabase (database) and Vercel (application).
- Free or busy, nothing more: to answer callers, Celya’s AI receptionist runs on OpenAI’s API, which does not use API data to train its models. It receives the free time slots Celya computes from all your bookings — never an event, its title or its details, nor which calendar a busy time comes from.
- The daily summary of your calendar (by WhatsApp or email) may show that a slot is “Busy” and at what time — never the event’s title. It is delivered through WhatsApp (Meta, see section 9) or our email delivery service, to you alone.
What we never do
- Read your event titles out to callers.
- Send your events (title, description, attendees or any other detail) to an artificial-intelligence provider.
- Use your Google data to train an artificial-intelligence model, ours or anyone else’s. Nor is it ever added to your AI receptionist’s knowledge base.
- Sell your Google data, use it for advertising, or share it with anyone other than our hosting providers and, for free and busy times only, OpenAI’s API (see above).
How long
| Situation | What we erase |
|---|---|
| An imported event ended 30 days ago | The event is deleted from Celya. |
| You disconnect Google Calendar from Celya | We delete the “Celya — Réservations” calendar from your Google account, revoke our access, and erase your access tokens and all data imported from that calendar. |
| Access is withdrawn or expires on Google’s side | We erase your tokens and the imported data as soon as we detect it, at the next synchronisation. We can then no longer reach the “Celya — Réservations” calendar, which you can delete yourself in Google Calendar. |
Removing access
- In Celya: Settings → Integrations → Disconnect.
- From your Google account: myaccount.google.com/connections.
Limited Use. Celya’s use and transfer to any other app of information received from Google APIs will adhere to the Google API Services User Data Policy, including the Limited Use requirements. Celya does not retain or use data obtained through Google Workspace APIs (including Google Calendar) to develop, improve or train generalized artificial-intelligence and/or machine-learning models, and does not transfer it to anyone for that purpose.
Questions: sales@celya.be.
9. WhatsApp notifications
Celya can send you notifications on WhatsApp. This is optional and off by default: you turn it on yourself in your Celya console (Settings → “Notifications WhatsApp”) by entering your WhatsApp number.
What we send
| Message | When, and what it contains |
|---|---|
| Confirmation | Once, when you register your number: “Your number is registered to receive your appointment notifications.” |
| Morning summary | Every day at the time you choose, if you turn it on: your business name, the number of appointments that day and, for each one (five at most), the time and the person’s name. A slot imported from Google Calendar only appears as “Busy”. On a day with no appointments, nothing is sent. |
- These messages go only to the number you registered.
- We never include your customers’ phone numbers.
- Celya never messages your customers on WhatsApp and sends no advertising.
What we keep
- Your WhatsApp number and the time chosen for the summary.
- A copy of each message sent (visible in your console) and its delivery identifier.
- Messages you write to Celya’s WhatsApp number.
Who processes these messages
Meta’s WhatsApp Business Platform (Meta Platforms Ireland Limited) sends the messages and processes them on our behalf under its WhatsApp Business data processing terms. This may involve transferring data outside the European Economic Area, covered by the safeguards Meta provides (EU standard contractual clauses, EU–US Data Privacy Framework).
Why, and on what basis
- Purpose: to let you know, on your phone, about the appointments Celya booked for you.
- Legal basis: your consent, given when you turn notifications on, and the performance of our contract.
How long
For as long as your subscription lasts, then deleted or anonymised as described in section 4. You can ask us to erase it at any time (section 6).
Stopping
- Turn off the morning summary in your console: it is no longer sent.
- Or click “Retirer mon numéro” (remove my number): sending stops immediately and your number is erased from your settings.
- Or write to us at sales@celya.be.
10. Changes
We may update this policy as our service evolves. The current version is always the one published on this page, with its "last updated" date.
