Customer Support

When you contact us for support via email we store a copy of your inquiry, our response, and any follow-ups, on servers operated by Fastmail, a third-party service. We retain customer support interactions so we can reference past interactions when you contact us for support with any of our products. We may periodically retain a backup of this data in an encrypted form.

Error Reporting

Our apps include a built-in error reporter that is designed to detect an error (when the app has an unexpected issue), and offer you the choice of reporting the error to us.

When an error is detected, you will be prompted with an alert describing the error and giving you the opportunity to send data about the error to our servers. We use your email address to follow-up on error reports when we are able to offer workarounds, or when we want to request more information about an error to improve our chances of permanently fixing the bug that caused the error.

When you agree to submit an error report, all of the information that will be sent to our servers is shown in the error email interface. Typically, this data includes any notes you add to the error report, diagnostic information about the error, generated by our error reporter, and an excerpt of your devices console log including messages that are specifically pertinent to our apps.

The information you submit when you report an error is sent as and email to us.
