Last updated 15 July 2026

1. Who controls this data

Yanis De Maesschalck, trading as YDM Design, Roombaardstraat 40, 9810 Nazareth-De Pinte, Belgium. VAT BE0699694751. Contact: info@ydmdesign.be.

2. What data we process

  • Your CRM OAuth access and refresh tokens, and your Billit API key and Party ID, stored encrypted on our servers.
  • Order and contact data from your CRM needed to create an invoice: customer name, address, email address, and VAT number where mapped.
  • Invoice log metadata: status, timestamps, and retry history for each invoice attempt.

3. Cookies

The dashboard uses a single session cookie to keep you signed in while it's embedded in your CRM. It's used only for authentication, is marked HTTP-only and secure, and carries no tracking or analytics purpose.

4. Why we process this data

We process this data to perform the invoicing service you configured, on the basis of the contract formed when you install and use the app.

5. Who we share data with

  • Your CRM platform: the source of your order and contact data.
  • Billit: generates and delivers the invoices, over Peppol or email.
  • Supabase: hosts our application database.
  • Railway: hosts the application itself.

6. How long we keep it

We keep your configuration and invoice logs for as long as the app stays installed, plus a reasonable period afterwards for bookkeeping and dispute-handling purposes. You can request earlier deletion by contacting us.

7. Your rights

Under GDPR, you can request access to, correction of, or deletion of your data, ask us to restrict or object to processing, and request a copy in a portable format. Contact info@ydmdesign.be for any of these requests.

8. International transfers

Some of our hosting providers may process data outside the European Economic Area. Where that happens, we rely on their standard contractual safeguards.

9. Security

API keys and access tokens are encrypted at rest, all traffic is served over HTTPS, and access to the app's endpoints is rate-limited.

10. Changes & contact

We may update this policy from time to time; the current version, with its update date, is always available at this page. Questions can be sent to info@ydmdesign.be.
