What Euler stores

Euler stores your authentication email with its identity provider so it can send sign-in codes. Conversations, preferences, plan status, monthly usage, and attachment metadata use a separate one-way keyed identifier instead of your email as the database key.

AI processing

Resend processes sign-in emails. Neon stores structured account and tutor data, and Vercel stores private uploaded or generated images. Your messages and selected attachments are sent to OpenAI to produce a response. Tutor chat requests disable OpenAI response storage. Realtime voice sessions are processed through OpenAI's Realtime API and are not stored as audio by Euler.

Your controls

You can delete all saved conversations and associated images from the account page. Billing records required by Stripe or applicable law are managed separately.

Audience

This launch version is intended only for adults aged 18 or older. Do not upload private information you do not want processed as part of a tutoring request.
