Your email address; your country or language where known; and delivery events for the messages we send you (delivered, bounced, opened, clicked). The events exist to keep lists clean and to tell us which guides were read. We never collect payment details, passwords or identity documents, and we never ask for them by email.
Your consent (Art. 6(1)(a) GDPR) or, where applicable, our legitimate interest in communicating with existing subscribers (Art. 6(1)(f) GDPR). Withdrawing consent is as simple as unsubscribing and applies to all future messages.
We use an email-delivery service and a hosting provider, both bound by data-processing agreements. If a processor is located outside the EU/EEA, the transfer relies on the EU Standard Contractual Clauses. We do not sell or share addresses for others' marketing.
For the duration of your subscription; afterwards a suppression entry so that we do not write to you again. Bounce and complaint records are retained for the same reason.
You may request access, correction, deletion, restriction or portability of your data, and object to processing, by emailing info@keelstonepost.com. You also have the right to complain to a supervisory authority, in particular in the EU member state where you live.
Every message carries an unsubscribe link and supports one-click unsubscribe where the mail client offers it. The unsubscribe page works too.
