Privacy Policy — Taiwan Stock Daily
Effective: November 8, 2026
Summary — Taiwan Stock Daily (台股日報) shows Taiwan-listed stock prices, a daily market recap and official notices. There is no sign-up or login and we never ask for your name, email or phone number. Your watchlist and settings stay on your phone. What leaves the phone is the requests for market data, feedback you choose to send, usage statistics, and the information ads need.
1. About this policy
This policy explains what information the Taiwan Stock Daily team ("we") processes when providing the mobile app Taiwan Stock Daily (com.twstockdaily.app, "the app"), why, for how long, and your rights.
2. Permissions the app uses
- Internet — to load prices, the daily recap, notices and ads.
- Notifications (only if you turn them on) — a morning reminder for the recap after each trading day. You can turn it off any time in the app's settings or in system settings.
- Run at startup — to restore the reminder you turned on after the phone restarts.
The app does not use your camera, microphone, photos, contacts or location (GPS).
3. What stays on your phone
- Your watchlist and its order, theme (light/dark), text size, notification switch and the last market data loaded (shown when offline).
- This is deleted when you uninstall the app or clear its data.
4. What we process and why

- Data held by Google services follows their policies (Google Privacy Policy).
6. Ads and your choices
- The app is free with ads. Where consent is required, the app asks on first launch; you can change it later under "More" in the app.
- You can reset or delete your advertising ID in Android Settings › Google › Ads.
7. Children
The app is not directed to children under 13 and does not knowingly collect their information.
8. Your rights
You can ask to see, correct or delete the feedback we hold from you. Since there are no accounts, please include when you sent it and what it said so we can find it. See section 10 for contact.
9. Market data and disclaimer
Market data comes from the Taiwan Stock Exchange and the Taipei Exchange via Taiwan's government open data platform (Open Government Data License, version 1.0). It is end-of-day data, not real-time quotes. This information is for reference only and does not constitute investment advice.
