The waitlist

When you join, we store your email, the devices you ticked, and which page you signed up from. We use it only to send your early access invite and important updates about Prowl. We don't sell or share it. Email us to be removed.

The app

• Your Disney password is typed on Disney's own login page. Prowl never sees or stores it.
• Sync stores your reading progress, library and lists so your devices match. Linking by Disney account keeps only a one-way hash of your Disney user id, never your tokens.
• Community shows your handle, profile picture and the lists you choose to share. Reading progress on shared lists is shared as counts only.
• Usage: we count how many devices open the app each day, with no content and no identity beyond a random device key.
• Comics stream from Marvel and are never stored by Prowl.

Deleting your data

In the app: Settings → Delete My Prowl Data on the Server. It removes everything the server holds for you.
