  • Address: Rue de Grand-Bigard 14, 1082 Berchem-Sainte-Agathe, Belgium
  • Email: rgpd@seido-app.com

As a preliminary point, the terms “personal data” must be understood within the meaning given to them in Article 4 of Regulation 2016/679 (the “GDPR“).

Processing of the managing Client’s data

By registering on Seido, the Client accepts that Seido may store, process and use the personal data collected upon registration, and that relating to Seido’s invoicing obligations towards the Client. This includes the possibility of citing the Client’s name in Seido’s customer references.

By registering on Seido, the Client consents to Seido, as a data controller, retaining and processing its data for the performance of the services, including for the commercialisation of additional services managed by third parties and offered by Seido.

Legal bases for processing:

  • Performance of the contract (Art. 6(1)(b) GDPR): for the provision of the Platform’s services, the management of the Client’s account, and invoicing
  • Consent (Art. 6(1)(a) GDPR): for the commercialisation of additional services, the use of marketing cookies, and promotional communications
  • Legitimate interest (Art. 6(1)(f) GDPR): for the improvement of our services, the security of the Platform, and the prevention of fraud
  • Legal obligation (Art. 6(1)(c) GDPR): for the retention of invoicing data and compliance with accounting and tax obligations

These personal data of the Client will be retained for the entire duration of use of the service and for a period of five (5) years after its termination.

The Client accepts that the communication of its personal information takes place from the free trial period onwards, where such a period has been requested by the Client.

Ownership and confidentiality of the data

The data belonging to the Client and hosted on Seido (information on owners, tenants, service providers, contracts, financial information, communications, intervention tickets, etc.) are and remain the property of the Client.

Seido undertakes to:

  • Keep this data strictly confidential
  • Make no copy of the data, apart from technical necessities
  • Make no use of it other than that provided for the performance of the services

Client’s responsibilities

The Client is solely responsible for the data it transmits to Seido for the purposes of hosting or using the Platform.

The Client warrants:

  • That this data belongs to it or that it has the right to use it and transfer it to Seido
  • The legality and accuracy of the data communicated to Seido

  • That it has fulfilled all the obligations that may fall to it with regard to the information/property/data that it shares with Seido and of which it is the holder

Data security

Data location

The personal data collected via the Seido Platform is stored and processed within the European Union. Seido uses hosting infrastructures located in the EU/EEA to ensure compliance with the GDPR requirements regarding international data transfers.

Seido implements appropriate technical and organisational measures to ensure the security of personal data:

  • SSL encryption for all communications
  • Secure environment for data storage
  • Staff training on confidentiality
  • Daily encrypted backups on an external server
  • Software firewall on all servers

However, as no mechanism offers maximum security, an element of risk is always present during the transmission of data over the Internet. Seido cannot be held liable for the loss of the Client’s data, even in the event of a failure of the Platform or the servers.

Notification of data breaches

In the event of a personal data breach likely to result in a risk to the rights and freedoms of the data subjects, Seido undertakes to:

  • Notify the Data Protection Authority within seventy-two (72) hours of becoming aware of the breach
  • Inform the affected Clients without undue delay where the breach presents a high risk to their rights and freedoms
  • Provide in the notification: the nature of the breach, the categories and approximate number of data subjects concerned, the likely consequences, and the measures taken or proposed to remedy the breach
  • Document all data breaches, including the facts, the effects and the corrective measures taken

Retention period

Personal data is retained for:

  • The duration of use of the service for the data necessary for the operation of the Platform (identification, communication, intervention, geolocation data)
  • Five (5) years after termination of the service for invoicing and contractual data
  • Three (3) years for marketing cookie data (LinkedIn) from the last consent
  • The duration of the session for technical and security cookies (Cloudflare)
  • The applicable legal periods for data subject to specific retention obligations

International transfers

Seido undertakes to ensure that all transfers of personal data outside the European Union are carried out in accordance with the GDPR and with the adequacy decisions or appropriate safeguards provided for by the regulations.

In the context of the use of third-party services (in particular LinkedIn and Cloudflare), certain personal data may be transferred to countries located outside the European Economic Area, including the United States. These transfers are governed by appropriate safeguards such as the Standard Contractual Clauses of the European Commission or the EU-US Data Privacy Framework for certified companies. You can obtain a copy of these safeguards by contacting rgpd@seido-app.com.

Changes to the policy

This privacy policy may be modified at any time. In the event of a significant change, users will be informed by email fifteen (15) days before the entry into force of the changes.

Data Processing Agreement (DPA)

For professional Clients acting as data controllers, Seido makes available a Data Processing Agreement (DPA) compliant with Article 28(3) of the GDPR. This DPA defines the subject matter, duration, nature and purpose of the processing, the types of personal data and the categories of data subjects, as well as the obligations and rights of the data controller and the data processor.

To obtain a copy of the DPA or for any question relating to the processing of data, please contact: rgpd@seido-app.com
