privacy policy

last updated august 30, 2026

the short version

We store as little as possible: your email address, your license records, and a session cookie. We don't run ads, we don't sell data, and we don't want more of your information than the service needs.

what we store

• Your email — it is your account. Used for sign-in links and purchase-related messages only. No marketing lists.
• License records — which tools your account owns, tied to payments processed by Stripe.
• A session cookie (da1yn_session) — keeps you signed in across da1yn.com tools for 30 days. No tracking cookies, no third-party analytics.

your practice answers

When you submit an interview answer for grading, the transcript is sent to our AI provider (Anthropic) to generate your feedback, subject to their data policies. We do not permanently store your practice answers or your grades — they exist to produce your feedback in the moment and live in your browser during your session. Speech-to-text happens in your own browser through your browser's built-in service.

who touches data

• Stripe — payments. Your card never touches our servers.
• Resend — delivers sign-in and license emails.
• Anthropic — grades practice answers, as above.

deletion

Email dalynbutler@gmail.com from your account address and we'll delete your account and its data. Note that deleting your account deletes your licenses with it.
