We're sorry if you couldn't find what you were looking for. Our team certainly does its best to deliver the content of high quality, and constantly improve our apps. If there's something you could suggest updating, please feel free to reach out to us. Your feedback would be highly appreciated.
In the meantime, if you've already cancelled your subscription and would like to get a refund, see this guide:
If you have iOS:
Please contact App Store's support team. Unfortunately, we can't make a refund for your subscription because we don't have access to your Apple ID account and proceeds from sale. All Apple payments are managed by Apple, and we don’t have access to them. So it is the App Store who issue refunds.
If you have Android:
Please send us your request to firstname.lastname@example.org with your receipt number (it looks like GPA.XXXX-XXXX-XXXX-XXXXX..0) and your user ID, and we'll issue the refund as soon as possible. You can see this information in the email from Google Play store which they always send to confirm the subscription made.
