You are responsible for keeping your login secure and for activity under your account. You can delete your account at any time from within the app.
Subscriptions and billing

Subscriptions renew automatically until cancelled. Manage or cancel a mobile subscription in your App Store or Google Play account; manage a web subscription through the billing portal or by contacting us. Refunds follow the policy of the platform that processed the payment (Apple, Google, or Stripe).
