Privacy policy
This policy explains what Derek Castillo Studio collects on derekcastillo.online, why we collect it, and how to have it removed. Last updated 10 November 2026.
What we collect
When you create an account, subscribe to updates or contact us, we collect the details you give us: your name, email address and any company details you choose to add. Our servers also keep standard technical logs such as the IP address, the time and the page requested.
How we use it
We use your details to operate your account, to send the email you asked for, to answer your enquiries and to keep the service secure. We do not use your data to build advertising profiles.
Account and service messages go to the address you registered with.
Marketing email is only sent with your consent, and every message carries a
one-click unsubscribe link plus List-Unsubscribe headers. You
can unsubscribe at any time from
the unsubscribe page or by writing to
hello@derekcastillo.online.
Sharing
We do not sell or rent personal data. We share it only with the service providers that host this site and deliver our email, and only as far as needed to provide the service, or where the law requires it.
Retention
Account data is kept while the account is open. Addresses that unsubscribe are removed from marketing sends immediately and kept on a suppression list so they are not added again. Contacts with no engagement for 12 months are deleted.
Your choices
Write to hello@derekcastillo.online to request a copy of your data, correct it or have it deleted. We answer data requests within 2 business days.
