What we store. How we use it.
Studio figures render and export in your browser. Study stores account and learning data and sends relevant content to our model provider. This page explains those differences and the controls available to you.

Studio figures and exports
- Studio figures render in your browser, and SVG and PNG exports are built there too: the image is not sent to our servers. Studio does not require an account.
- The Studio editor, its share links and its HTML downloads were retired in November 2026. Drafts the editor saved in your browser's local storage are no longer read by the site; you can remove them with your browser's site-data controls.
Study data we store
- Account email and authentication records in Supabase, plus sign-in state in browser cookies.
- Resume PDFs you upload, extracted resume text, generated STAR stories, and other profile context you choose to save.
- Saved session topics, messages, and stage progress.
- Usage counts that enforce plan allowances, and Stripe customer and subscription identifiers for Study billing.
How your content is used
- Study sends the relevant messages, profile context, answers, and submitted code to Anthropic to generate explanations, STAR stories, and feedback. Resume uploads are optional. Studio figures do not make model API calls.
- For research-sensitive topics and current-information questions, a separate Anthropic lookup can search primary sources using the public catalogue topic. Resume text, private conversation text, and submitted code are not included in those search queries. Dated reference context may be cached for up to six hours; a source lookup does not guarantee that every generated claim is correct.
- We do not train models on your content or sell it to advertisers. Anthropic states that it does not use commercial API inputs or outputs for model training by default; its own processing and retention policies apply.
- Private Study records use access controls scoped to your user ID. These controls are intended to restrict access to your account; they are not a guarantee against every security risk.
Browser storage and analytics
- Cookies maintain sign-in state and the guest session allowance. A short-lived return-path cookie remembers where you wanted to go while signing in. Browser storage also keeps settings and any learning activity shown as saved locally on this device. This tab’s session storage keeps a bounded copy of your last completed guest Study session for recovery, with a seven-day expiry.
- PostHog receives page visits, explicitly recorded product interactions, failure categories, and performance measurements. When you sign in, analytics activity is associated with your account ID. Vercel Web Analytics also measures website visits.
- Automatic click/text capture and session replay are disabled. Analytics URL queries keep only approved navigation and campaign fields; URL fragments, sign-in codes, draft references and checkout receipts are removed. First-touch campaign labels are kept for attribution. Custom topic text, search text, email addresses and raw error messages are excluded from our product events. Account-linked usage is not anonymous.
Who processes your data
- Supabase — authentication, database records, and resume file storage.
- Anthropic — model requests for Study explanations, resume analysis, and code feedback.
- Stripe — subscription payments. Payment card details are entered through Stripe Checkout, not our application servers.
- Vercel — application hosting, request handling, and website analytics.
- PostHog — product analytics, account-linked usage events, error reporting, and performance monitoring.
Your controls
- You can edit profile text and STAR stories and delete individual sessions in the app. Removing extracted resume text does not by itself delete a previously uploaded PDF.
- Email liminalmlprep@gmail.com to request an account data export or deletion, including uploaded files and associated analytics records. We respond to deletion requests within seven days.
- Local browser data can be removed through your browser’s site-data controls.
