Frequently asked questions

Is it safe?

Yes. It is the same app as the website, served from our domain over HTTPS. Invoices are read on your device and never sent to any server.

How do I sign in with my subscription?

After purchase you create a passkey: on your other devices you sign in with fingerprint, Face ID or device PIN, with no password. It is two-factor by design.

Does it update itself?

Yes, every time you open it online it fetches the latest version.
