You can check your subscription either via the Binance website or mobile app. For the former, simply open the website, go to 'Orders', choose 'Earn History', then click 'Range Bound'. Meanwhile, if you use the mobile app, you can go to 'Wallets' and choose 'Earn'. Tap 'Flexible Savings' and change the settings to 'Range Bound'. You'll be able to see all of your current subscriptions and settlement items.
