What data we collect

Why we use it

We do not sell your data, and we do not use it for anything else.

Leads we handle for clients

When we run ads for a client, the people who respond to those ads share their details with that client. The client decides what happens with those details; we process them only on the client's behalf and under a processing agreement. Questions about such data are best sent to the business you contacted.

Who we share it with

We use a small number of trusted services to run our business, and they only receive what they need:

Some of these providers may process data outside the European Economic Area. Where they do, they rely on safeguards required by the GDPR, such as the EU standard contractual clauses.

How long we keep it

We keep contact details for as long as we are in touch, and delete them within 12 months after our last contact if you did not become a client. Client records are kept for as long as the law requires, which in the Netherlands is 7 years for financial records.

Cookies

This website does not use tracking or advertising cookies.

Your rights

You can ask us to see, correct or delete your data, to limit or object to how we use it, or to receive a copy. Email mike@boostbutler.com and we will respond within one month. You can also file a complaint with the Dutch data protection authority, the Autoriteit Persoonsgegevens.

Changes

If we change this policy, we update the date at the top of this page.
