Access under Art. 15 GDPR
Every body must tell you what data it processes about you, where it came from and who it is passed to. Cleanup files the requests and collects the answers in one place.
Access and erasure requests to data brokers and credit agencies, with deadline tracking and a route to the supervisory authority. The first step is not erasing but finding out.

Alongside what can be found about you online, a second collection exists: data at credit agencies and address brokers that nobody can search for and that nevertheless decides about you - on a tenancy, an instalment plan, an insurance application. Cleanup makes that collection visible.
Every body must tell you what data it processes about you, where it came from and who it is passed to. Cleanup files the requests and collects the answers in one place.
Incorrect data must be rectified under Art. 16. Erasure under Art. 17 applies where no retention duty stands in the way.
The response period is usually one month. If it passes, Cleanup reminds you and prepares the next step.
If an answer fails to come or is inadequate, a complaint to the data protection authority remains open. The documentation for it is already in place.
German-speaking countries have no landscape of people-search services like the US; accordingly there is nothing here to opt out of wholesale. What matters are credit agencies and address brokers - and there an erasure claim regularly fails against statutory retention duties and legitimate interests. What is enforceable is access, not erasure. Anyone promising you otherwise is selling you a disappointment.
One entity, 300 messages a month, three search terms under observation and a monthly report. No payment method, no commitment, no notice period.
