A person reads these.
There is no ticketing system and no chatbot. Two addresses, both monitored, both answered by someone who worked on the thing you are writing about.
Support
Buying, delivery, refunds, installation, anything about using the app. If your download link has not arrived, this is the address.
support@coffershield.comWe aim to reply within two business days.
Security reports
If you have found something real in the application, the vault format or the backup handling, we would much rather hear it from you than from a customer.
security@coffershield.comReports are read by a person and answered. The whitepaper’s Appendix B publishes what previous reviews found.
One thing we cannot help with. We cannot open your vault, reset your master password, or verify your identity to let you back in. There is no copy of your data on our side and no key on our side. That is not a support policy we could change if we wanted to — it is the architecture. If you are locked out, the routes back in are the ones you set up in advance.
Before you write
Three of these answer most of what arrives:
Protect what matters.
One payment. Lifetime ownership.
Fourteen-day refund. No account to create, and nothing to cancel.
