AdresDirect 365: privacy statement

This statement is about the AdresDirect 365 app in Microsoft Dynamics 365 Business Central, published by Van Oosten Software. It is written for the Business Central customer that uses the app. This website has its own separate privacy statement, linked at the bottom of every page.

The short version

The app looks up addresses in the BAG of the Kadaster and fills them in in your own Business Central environment. The request goes straight from your environment to the PDOK Locatieserver or, if you choose it, with your own API key to the Kadaster's BAG API; nothing passes through Van Oosten Software. Van Oosten Software receives only technical telemetry, without post codes, house numbers or addresses.

What data the app processes

In your own Business Central environment:

  1. The house number, in a new field on customers, vendors, contacts, ship-to addresses, vendor order addresses, locations and the company information.
  2. Address, city, province and post code, in the standard fields of those same cards.
  3. Post codes with city, country and province in the standard Post Codes table, when Save Post Codes is on. Without street and without house number.
  4. If you choose the BAG API: your API key, encrypted per company in isolated storage.

Who is responsible

Addresses of sole traders and private persons can be personal data, especially with a house number. The app records them in the same fields you would otherwise type them into. You, the Business Central customer, are the controller for that data: you decide whose addresses you record, why and for how long. Van Oosten Software supplies the app but does not process this data on your behalf.

The lookup at PDOK or the Kadaster

To look up an address, your Business Central environment sends the post code and, when it is filled in, the house number to the address service you choose. By default that is the PDOK Locatieserver, the open service for government geodata that the Kadaster runs: no key and no account. If you choose the BAG API Individuele Bevragingen, the request goes to the Kadaster, with your organisation's key and under the terms you agreed with the Kadaster when you requested the key. No names or other data from the card go along, and the request comes from Microsoft's data centre, not from the user's computer. By default this happens only while someone types on a card; for an import or integration only when Look Up for Imports and APIs is on. PDOK and the Kadaster are therefore not sub-processors of Van Oosten Software, and Van Oosten Software does not see the request or the answer.

Where the data stays

In your own Business Central environment, at Microsoft, under the terms and the geography you agreed with Microsoft. Van Oosten Software has no access to your environment and receives no copy of your data.

Telemetry

AdresDirect 365 sends technical usage telemetry to the Azure Application Insights of Van Oosten Software, stored in the European Union (West Europe). It records whether a lookup filled in an address, found nothing or failed, with a fixed reason (for example key refused, limit reached or not reachable) and the address service used, and when the setup was completed or the address service was changed. It never contains post codes, house numbers, addresses, names or the API key.

Sub-processors

For the telemetry: Microsoft, as the provider of Azure Application Insights. Nobody else. PDOK and the Kadaster are not sub-processors of Van Oosten Software: your own environment makes the request, directly.

How long data is kept

Addresses and house numbers stay in your environment for as long as you keep them. Post codes in the Post Codes table stay until you delete them, also when you uninstall the app. Telemetry is kept for at most 90 days.

Rights of the people involved

Anyone whose address is in your records exercises their rights with you, as the controller. The house number is in an ordinary field on the card, so you can view, change or erase it like any other address field. Questions about the app itself can be sent to info@van-oosten.nl.
