Building

Project is using git-crypt to encrypt all credentials, contributors need to contact to repo's owner to get decryption key.

Install git-crypt: MacOS, Ubuntu, Windows

After saving key somewhere in your directory, command:

git-crypt unlock <path_to_key>

If all files are decrypted, done! You can run code normally.

Roadmap

• iOS/Android Push Notification
• ZNS to forgot password flow (on my way to find another solution)
• Export Excel statistics
