Detective Doctor
Detective Doctor (detectivedoctor.com and the Detective Doctor apps for Android and iOS) sells and delivers medical e-books and video courses. This policy explains what we collect, why, who we share it with, and how to delete it. Last updated 13 October 2026.
Account details you give us: name, email address, and optionally phone number, qualification and profile photo. If you sign in with Google or Apple, we receive your name and email from them. Purchases: the products you bought, order and invoice records, and the payment reference. Learning activity: reading and lesson progress, saved items and playlists, recent searches, reviews you post, and support messages with any screenshot you attach. Highlights, notes, pen marks and photos you pin onto a page stay on your device and are never uploaded. Device information: a device identifier, device name, platform, app version, IP address and approximate city, used to keep you signed in and to enforce the three-device limit.
We do not collect card, UPI or bank details — those are entered in Razorpay's checkout and never reach our servers. We do not use advertising, ad identifiers or third-party analytics, and we do not sell your data.
To create and secure your account, deliver what you bought to every device you sign in on, sync your progress, send receipts and account emails, answer support requests, prevent account sharing and fraud, and meet tax and accounting obligations. Every purchased PDF carries your name and email on each page so that a leaked copy can be traced to its account.
Only the service providers that run the product, each for its own job: Razorpay (payments), Railway (application hosting and database), Cloudflare R2 (file storage), Bunny.net (video streaming), Vercel (website hosting) and Brevo (transactional email). Google or Apple, if you use their sign-in. We disclose data to authorities only when the law requires it.
All traffic is encrypted in transit (HTTPS). Passwords are stored only as salted hashes. Downloaded lessons and books are encrypted on your device and cannot be opened outside the app.
You can delete your account at any time from Profile → Delete account in the app, or at detectivedoctor.com/account/delete. Access ends immediately. Your account and the data linked to it are permanently erased 30 days later; the 30-day window exists so an accidental deletion can be undone by contacting support. If you can't sign in, email support@detectivedoctor.com from your account's email address and we will delete it for you.
Detective Doctor is made for medical students and professionals and is not directed at children under 13.
