Contact ChangeSignal

Send a message and we reply by email. You can also write directly to info@changesignal.net.

How we handle your message

Your message and the address you give are sent as an email through our email provider (Resend) and delivered to our business mailbox, which runs on Google Workspace. The message is not saved in the ChangeSignal application database — but it is a real email, so it stays in that mailbox until we delete it, and both providers keep their own operational logs for a time.

We keep enquiries for up to 12 months and delete them sooner once they are resolved. Correspondence that becomes part of a customer relationship is kept for as long as that relationship needs, and anything with a tax, accounting or legal-defence reason to survive is kept for as long as that requires. We use it to answer you and for nothing else — no mailing list, no marketing, no analytics.

Because these messages live in a mailbox rather than in the product, the self-service export and deletion inside ChangeSignal do not reach them. Ask us and we will find, correct or delete your correspondence by hand.

To limit abuse we keep a one-way, salted hash of the network address a submission came from, together with a count, for one hour. It holds no message, no name and no email address, and it is deleted once the hour has passed.

If you have contacted us here and then find yourself without access to the internet, say so and we will arrange another, non-electronic way to reach us.
