The Android voucher code is only valid for 3 months. We will automatically send you a new code every 3 months via email.
To redeem the new voucher code, cancel the existing subscription in time (at least 1 day before it expires, before it would turn into a paid subscription).
After the subscription has expired (preferably 1 day after the end of the subscription), you can purchase your new subscription using the coupon code.
