Deceptive
Your data comes with a price, so this app is not free. I do not trust a developer who forces you to subscribe to something — before offering you anything in return.
Response from developer
Thank you for your feedback. We, the developer do not receive any personal information from when you subscribe. Nether do we receive any sensitive data from you when you use the app. When you subscribe you can use the app for free for 3 days and then decide if you want to continue with paying for subscription.
