Contact
Two addresses, both read by a person. Pick whichever fits and write in your own words — there is no form to fill in.
Support and general questions
Problems with the app, questions about your subscription, corrections to an exercise, bug reports and suggestions. We aim to reply within 3 working days.
Before you write, the support page answers the common ones in full — cancelling a subscription, restoring a purchase, exporting your data, and what to include in a bug report.
Privacy and data protection
Questions about the privacy policy, and any data protection request under UK GDPR. Because Comeback holds no personal data about you, most requests are answered by pointing you at the export and delete controls already in the app — but write anyway and we will confirm it properly.
Why there is no contact form
A form on a static site needs somewhere to send the submission: a server we run, or a third-party form processor. Either one would mean your name, your email address and your message passing through infrastructure we asked you to trust — on a site whose entire argument is that the app has no server and talks to no third parties.
It would be a small inconsistency, but it would be a real one. So there is no form. Your email client already does the job, and your message goes directly to us with nothing in between.
For the same reason this site sets no cookies, runs no analytics and loads nothing from another domain. There is nothing here that watches you read it.
