Planned changes
No subprocessor additions or replacements are currently planned. Anything pending appears here, with its effective date, before it starts processing customer data.
How to object
Customers who object to a planned subprocessor have 14 days from the notice date shown above to raise the objection in writing, to legal@proculink.eu. Where the objection cannot be resolved, the customer may terminate the subscription without further fees for the unused remainder of the term.
We do not operate a notification mailing list — the notice is the dated publication on this page, which means it does not depend on anyone remembering to send it. Customers who need the notice delivered to a named contact can have that written into their agreement; email the address above.
