What it is
App Lock asks for a 4-digit PIN, or your fingerprint or face, before anyone can open InvoiceZen on your phone. It keeps your clients' details and what they owe you private if your phone is lost or borrowed. When you unlock, you are back exactly where you were.
Why you’d use it
Your phone holds your clients’ names, numbers and what each one owes you. If your phone is lost, stolen or just borrowed by a family member, App Lock keeps that private. Looking after client details is also what POPIA, South Africa’s privacy law, expects of you.
What you need first
- A 4-digit PIN you will remember. You choose it when you turn App Lock on.
- Fingerprint or face unlock (optional). Set it up in your phone’s own settings first if you want to use it.
How to do it
- On the InvoiceZen tab, tap the settings icon at the top right to open Business Profile.
- Scroll down to App Lock and turn on Enable App Lock.
- Type a 4-digit PIN, then type it again to confirm.
- To unlock with your fingerprint or face too, turn on the switch below it. It is named after your phone’s method, such as Face ID or Fingerprint.
From now on InvoiceZen asks for your PIN, fingerprint or face when you open it, and whenever you have been out of the app for more than 30 seconds. A quick trip to WhatsApp or your calculator does not lock it. When you unlock, you are back on the same screen, with anything you were typing still there.
To choose a new PIN, tap Change PIN in the same section. To switch the lock off, turn off Enable App Lock and confirm with your fingerprint, face or PIN.
What it costs
Nothing extra. App Lock is included on every plan, including Free.
Common questions
What happens if I type the wrong PIN?
After five wrong tries, the app makes you wait 30 seconds. Then you get five more tries. Nothing is ever deleted because of wrong PINs.
I forgot my PIN. What now?
There is no “forgot PIN” button on the lock screen.
If you turned on fingerprint or face unlock, use it to get in. Then turn Enable App Lock off, turn it on again, and choose a new PIN. (Change PIN won’t help, because it asks for the old one.)
If you only had a PIN, delete InvoiceZen from your phone, install it again and sign in with the code we email you. Everything that has synced comes back. Anything you created while offline that has not synced yet is lost, so only do this as a last resort.
Does logging out turn App Lock off?
No. App Lock belongs to the phone, not your account. If you log out and sign in again, the lock screen still asks for your PIN.
