Privacy Policy

Last updated: March 2026

ProteinDeck ("we", "our", or "us") is committed to protecting your privacy. This policy explains what information we collect, how we use it, and your rights.

Information We Collect

ProteinDeck collects minimal data necessary to operate the app:

• Anonymous device identifier — a randomly generated ID stored on your device, used solely for AI request rate limiting. This is never linked to your identity.
• StoreKit transaction ID — if you subscribe to Premium, your Apple transaction ID is stored locally on your device to verify your subscription status. We never receive or store payment information.
• Study data — your flashcard decks, review history, and quiz results are stored locally on your device using SwiftData. This data never leaves your device unless you explicitly use iCloud backup.

AI Features

When you use AI features (clinical notes, quiz generation), the following data is sent to our secure backend:

• Protein name, gene name, and function text — to generate relevant content
• Your anonymous device/transaction ID — for rate limiting only
• Your selected language preference

This data is processed via OpenAI's API and is subject to OpenAI's privacy policy. We do not store AI prompts or responses on our servers beyond the immediate request.

Data We Do Not Collect

• We do not collect your name, email, or any personal identifiers
• We do not track your location
• We do not use analytics SDKs or advertising trackers
• We do not sell your data to third parties
• We do not create user profiles

Third-Party Services

ProteinDeck uses the following third-party services:

• UniProt — protein database queries. See UniProt's privacy policy.
• AlphaFold (EMBL-EBI) — 3D protein structure data. See AlphaFold's privacy policy.
• OpenAI — AI content generation. See OpenAI's privacy policy.
• Apple StoreKit — subscription management. See Apple's privacy policy.

Data Retention

All personal study data (decks, reviews, quiz results) is stored locally on your device and is deleted when you uninstall the app. Anonymous rate-limiting identifiers on our backend are automatically deleted after 30 days of inactivity.

Children's Privacy

ProteinDeck is not directed at children under 13. We do not knowingly collect data from children.

We may update this privacy policy from time to time. We will notify you of significant changes by updating the "Last updated" date above.
