What data we collect and why we collect it


Invoicer - A person creating and sending an invoice on

Invoicee - A person receiving an invoice sent on

Personal Information

When signing up, we ask for an email and password. We never log your email address.

When you sign-in, a record of your session is stored. With that record, we know when you signed in. We do not collect any other information.

Invoices typically will contain the invoicers's information and the invoicee's information, such as addresses, names, and billable work. Note that providing this information is not strictly necessary and is up to the invoicer.

When you send an invoice, a record of the recipients is stored.

All information pertaining to an invoice may be deleted by the user at any time. When a user deletes an invoice, related data will also be deleted (such as when an invoice was sent and who it was sent to).

How does CannonVoice collect personal information?

Glad you asked! We transmit personal information from your computer to our servers over an HTTPS/TLS connection. Rest-assured, we never use plain-ol' HTTP here.

Your data is only stored in a Postgres database (even your PDF invoices). In cases of sensitive information like passwords, we cryptographically hash and salt your data, such that we could never re-construct your sensitive data.

Why we collect

We need some data to be useful. We need to store the invoice data itself so we can build a pdf and send it to your recipients. The recipients need to be stored for retrying in case of failure and for general invoicer book-keeping.
