Your manuscript is yours. This page explains exactly what that means in practice.

Open Expression and other controls live in Settings.

​
Your writing is never training data

Quarkle does not train on your writing. We also ensure our AI providers cannot train on your data. It’s used only to answer your request in the moment, then it’s done its job. We don’t sell your data, and we don’t want to. We’d rather earn your subscription with a better product.

​
What’s private, and what isn’t

By default, a manuscript is private to you. It becomes visible to others only when you choose to:
  • Invite a collaborator. They get read-only access. See Sharing.
  • Turn on a public reading link. Anyone with the URL can read it, until you turn it off.
Nothing you write is shared, indexed, or made public unless you take one of those steps.

​
How mature content is handled

Quarkle supports serious fiction, including dark and mature themes. To keep the default experience appropriate while still letting adult authors write freely, each Chat message you send is first checked by a dedicated content-safety model against a clear policy.
  • For most requests, nothing changes. Your message goes straight through.
  • If a request involves mature or explicit content and you’re on Basic, Quarkle will point you toward Pro’s Open Expression mode rather than filtering silently.
  • If you’re a Pro user with Open Expression enabled, eligible requests are routed to an unfiltered model built for that content.
Open Expression is opt-in and gated behind an 18+ confirmation and terms acceptance the first time you turn it on.
Open Expression is a Pro feature. You enable it from your Settings → Preferences. See Manage your account.

​
Deleting your data

You’re in control of removing your data, too.
  • Delete a manuscript from its ”…” menu in the Studio. This can’t be undone.
  • Delete your account from Settings → Danger → Delete Account (you type delete my account to confirm). This immediately and permanently wipes your data from our servers. It cannot be recovered. See Manage your account.
