MySudo for iOS:
No, you will be refunded a prorated amount of the original subscription price.
For example, if you purchase the SudoGo plan and then decide to upgrade to SudoMax before the end of your renewal cycle, you will immediately be upgraded and receive a refund of the prorated amount of the SudoGo subscription. Your monthly renewal date is now the day of the month you purchased your new plan.
MySudo for Android:
Please contact us at firstname.lastname@example.org if you have upgraded your plan and did not receive a refund.
