Privacy Policy
This is the privacy policy for Biotech Pulse ("the app"), published by the operator of bioturd.com.
Summary
Biotech Pulse does not require an account, email address, or password. It does not collect your name, contact information, or any personally identifying information. It does not sell or share data with advertisers.
What we store
1. Anonymous device identifier
When you first open the app, a random UUID is generated on your device. This identifier is not linked to your name, phone number, email, or Apple ID. It exists so we can deliver push notifications for tickers on your watchlist without requiring you to create an account.
2. Watchlist
The list of stock tickers you choose to follow is stored locally on your device (in AsyncStorage) and mirrored to our Supabase database, associated only with your anonymous device UUID.
3. Expo push token
If you grant notification permission, Apple issues an anonymous push token that lets our server deliver notifications to your device via Apple's Push Notification service (APNs). We store this token associated with your device UUID. The token does not identify you.
4. Alert log
Each push we send to you is logged (event, timestamp, delivered/opened status) so the in-app Alerts inbox can show your history. This log is scoped to your device UUID.
5. No analytics, no ads
We do not use third-party analytics SDKs. We do not serve ads. We do not use cookies or tracking pixels. The iOS app does not access your contacts, photos, location, health data, or any other OS-level data.
Third parties involved in delivering the service
- Supabase (database + serverless functions) — stores events, your anonymous device UUID, and your watchlist. Supabase privacy policy.
- Expo Push Service (push notifications) — forwards our push messages to APNs. Expo privacy.
- Apple Push Notification service (APNs) — delivers notifications to your device.
- GitHub Actions (data ingestion) — runs our data collection scripts on a 15-minute schedule.
- Public data sources — openFDA, Endpoints News, STAT News, Fierce Biotech, Fierce Pharma. We do not share any user data with these sources; we only read their public feeds.
Your controls
- Delete your data: uninstall the app. Your local watchlist is wiped with the app. Your anonymous device UUID row (and associated watchlist rows) on our server becomes orphaned and is purged in regular cleanup.
- Revoke notifications: iOS Settings → Notifications → Biotech Pulse. The push token becomes invalid immediately.
- Manual deletion request: email hello@bioturd.com with the device UUID shown in the app's Settings screen (coming in a future release) and we will delete the row within 7 days.
Children's privacy
Biotech Pulse is intended for adults (18+) interested in biotech investing. We do not knowingly collect data from children under 13.
International users
