Cyd - Claw back your data from Big Tech

How Cyd Works

Cyd is a desktop app for macOS, Windows, and Linux that can help you save and delete your data from X (with other platforms coming soon). To start, log in to your X account inside of Cyd, give Cyd instructions on what you want it to do, and then Cyd takes care of the rest.

Cyd doesn't use the API. Cyd works by scrolling through X's website and clicking buttons on your behalf. Everything that Cyd does, you could do yourself with nothing more than a web browser and an infinite amount of time. X can't cut off API access to stop you from controlling your data with Cyd.

Cyd can delete your tweets, except for what you want to keep. For example, you can tell Cyd to delete tweets older than 30 days unless they got at least 100 likes or retweets... Or, you can just delete everything. The choice is yours.

Cyd helps you abandon X while keeping your username. If you're one of the millions of people fleeing X, it's better to delete all of your tweets (and unfollow everyone, which Cyd can do for you) but keep your account activated than to delete your account. This way, other people can't take over your username and impersonate you, and you can leave your account with a message telling your followers where to find you.

Cyd can delete your likes and direct messages. Likes and DMs are private on X, but that data is still accessible to anyone who hacks your account, and to X itself.

Cyd saves a local backup of your data. Before deleting your data, Cyd can build a local, browsable database of your X data, complete with HTML snapshots of your tweets.

Cyd runs directly on your computer, not on our servers. We don’t have access to your X account, or to any of the data in it.
