This page states plainly what the app actually does with your data. It isn't a substitute for a lawyer-reviewed policy; if you need one for a specific purpose (a data request, a compliance review), contact help@getsubswitch.com.
Your email address, sign-in sessions, and your subscription status with Stripe. We never see or store your card number: Stripe holds that, and our servers only ever receive a customer and subscription id back.
Your watchlist, budget, live-TV selections, and the rotation plan we build from them. What you tell us you already pay for (a cable bill, other streaming subscriptions) is stored so your savings figures stay accurate over time.
Sign-in links and account and billing emails are sent through Postmark. Reminders, price alerts and setup tips are optional. Turn them off in Settings, or with the link at the bottom of any of them, and we stop sending them.
Email help@getsubswitch.com to close your account and have your data removed.
