Billing questions
Do I need a PayPal account?
Not necessarily. In most countries PayPal lets you pay with a debit or credit card without creating an account.
Why is the price in US dollars?
One price for every country keeps things simple. Your card or PayPal converts it to your currency when you pay.
What if a renewal fails?
PayPal retries. If it still fails, Pro turns off but your saved words stay; you can view and review them all, you just can't save more once you have over 100.
Where do I cancel renewal?
On your Vikaidu account page, or in the automatic payments section of PayPal.
