Most tech platforms are controlled by a tiny group of powerful billionaires. You don't OWE them your data. Even posting on Bluesky is a privacy nightmare. Why should our social media posts remain on the internet forever? With Cyd for iPhone, you can: - CREATE A LOCAL, PRIVATE BACKUP OF YOUR DATA, including Bluesky posts, reposts, likes, bookmarks, and chat messages. - CHOOSE WHAT YOU WANT TO DELETE. You can delete it all, or you can be selective, deleting most of it but keeping what went viral. - SCHEDULE AUTOMATIC DELETION, keeping your online data as ephemeral as you want over time. The Cyd developers can't access your accounts or your data. - Cyd runs directly on your device, not on our servers. - Cyd is designed so that we don't have access to your accounts, or to any of your data in those accounts. We don't even record what your username is. - When you sign into a Bluesky account in Cyd, you grant the app running locally on your phone permission to access it, not us, the developers of the app. Cyd is open source.

Verdict
The clearest difference is update cadence: Cyd at weekly against ATP Nexus's every 2 months. Cyd also leads on iOS requirement (16.4 vs 26.1). ATP Nexus's advantage is device support (5 vs 2). On price, ads and in-app purchases there is nothing between them.
