Privacy Policy
Last updated: 11 July 2026
This policy explains what CaseStudy2Win (“we”, “us”) collects when you use casestudy2win.com, why we collect it, who we share it with, and the choices you have. We only collect what we need to run the practice tool.
Who we are
CaseStudy2Win is an AI-powered practice tool for sales and interview scenarios, founded by Sajeed Ahmed. For any privacy question or request, contact us at privacy@casestudy2win.com.
What we collect
- Account details. Your email address, and if you sign up with Google, the basic profile Google returns (name, email). Sign-in and passwords are handled by our authentication provider (Supabase) — we never see or store your password.
- Practice content. The scenarios you generate and the written or spoken answers you submit, along with the scores, evaluations and coaching we produce from them.
- Voice data. If you use voice roleplay, your microphone audio is streamed to a speech-to-text provider (Deepgram) to transcribe what you say; replies are turned into audio by a text-to-speech provider (ElevenLabs). We store the transcript and scores, not the raw audio.
- Usage & cost data. Aggregate technical metadata about each session (which feature, model, token counts, timestamps) so we can measure cost and reliability. This does not include the text of your answers.
- Feedback. Ratings or comments you choose to submit.
How we use it
- To generate scenarios and evaluate your answers.
- To keep a history of your practice so you can track progress.
- To operate, secure, debug and improve the service.
- To measure usage and cost, and (when paid plans launch) to enforce plan limits and process payments.
- To contact you about your account or access requests.
We do not sell your personal data, and we do not use your answers to train third-party AI models beyond what is needed to return your result for that session.
Who processes your data (sub-processors)
We rely on a small set of vetted providers to run the service. Your data is shared with them only to deliver the features above:
- Supabase — database, authentication and storage.
- Anthropic (Claude) — generating scenarios and evaluating answers.
- Deepgram — speech-to-text for voice roleplay.
- ElevenLabs — text-to-speech for voice roleplay.
- Vercel and Railway — hosting the website and backend.
- Stripe — payment processing, once paid plans launch (Stripe handles card details directly; we never store them).
Cookies
We use a single essential cookie to keep you signed in, plus your browser's local storage to maintain your session. We do not use third-party advertising or cross-site tracking cookies.
How long we keep it
We keep your account and practice history while your account is active. If you delete your account, we remove your practice answers within 90 days. Some aggregate, non-identifying usage and cost records may be retained longer for accounting and analytics. We may also retain limited data where the law requires it.
Your rights
Depending on where you live (for example under GDPR or CCPA), you can ask us to:
- Access the personal data we hold about you.
- Correct inaccurate data.
- Delete your account and associated practice data.
- Export a copy of your data.
- Object to or restrict certain processing.
To exercise any of these, email privacy@casestudy2win.com. We will respond within a reasonable time and within any period the law requires.
Security
We protect your data with encryption in transit, access controls, and reputable infrastructure providers. No system is perfectly secure, but we work to keep your information safe and to limit access to what is necessary.
Children
CaseStudy2Win is intended for working professionals and is not directed at children under 16. We do not knowingly collect data from children.
Changes to this policy
We may update this policy as the product evolves. We will change the “last updated” date above and, for material changes, take reasonable steps to notify you.
