Contact
There is no form here that pretends to send. This composes an email and hands it to your mail app, so nothing reaches a server of ours in between.
What is it about
If no mail app opens, copy the message and the address and send it however you normally would. The address is hello@qrpress.org.
Before you write about a lost project
We cannot recover it. Codes are stored only in your browser and we hold no copy, that is the whole design. If the storage was cleared, the project is gone unless you exported a backup. Sorry; there is no better answer.
