First off, it is to be noted that we have fixed prices only in USD as shown on our Pricing page.
You can pay in your national currency with the price being re-calculated based on current exchange rate.
When you start a subscription in your national currency, your price gets "locked" for the time your subscription remains active and it keeps auto-renewing with original price which is not subject to exchange rates variations.
But if your subscription gets cancelled and you start a new one, you may get a new pricing based on current exchange rate and it will most likely differ from what it used to be.
In case you need to get payment link in USD to lessen expenses caused by exchange rates, you may contact our support team for assistance.
