Frequently asked questions

How do I sign in with Apple?

You can sign in using your Apple ID on iOS devices or on the web. On iOS, Parenthesis uses the native Authentication Services framework. Your name and email (or a private relay address) come from Apple, with no extra forms.

How do I delete my account and data?

You can delete your account at any time directly inside the app:

  • On iPhone: Open the profile sheet on the Today screen, scroll to the bottom, and tap Delete account.
  • On the web: Click your profile menu in the upper corner and select Delete account.

Deleting your account permanently erases all your conversations, uploaded syllabi, subjects, study history, and revokes your Apple sign-in token immediately.

How do parent accounts work?

Parent accounts allow a parent or guardian to follow a student’s academic progress (time studied, subjects worked, weekly mastery recaps) without ever seeing or reading the student’s private conversations with the companion. Parents can link via an invite link generated in the app.

What if the companion gets an answer wrong?

Parenthesis is designed to guide your thinking rather than hand you pre-baked answers. Because it relies on AI models, it can occasionally make mistakes. Always check its reasoning and its working before submitting assessed work.
