Last updated: 2026-10-09
By using DuoRead ("the app"), provided by Sakura5, you agree to these terms.
License
We grant you a personal, non-transferable license to use the app on your Apple devices, subject to the App Store Terms of Service.
Subscriptions
The app may offer auto-renewable subscriptions. Payment is charged to your Apple ID at confirmation of purchase. Subscriptions renew automatically unless cancelled at least 24 hours before the end of the current period. Manage or cancel anytime in your App Store account settings. Any unused portion of a free trial is forfeited when you purchase a subscription.
DuoRead Premium
DuoRead is free to download, and every new install starts with a 3-day free trial of all features. After that the free tier includes the complete reader, highlights, notes and the dictionary for up to 3 books.
DuoRead Premium unlocks the AI study tools (Explain, Translate and Summarize, up to 100 requests a day) and an unlimited library. It is an auto-renewable subscription: $5.99 per week, $15.99 per month or $69.99 per year; the yearly plan includes a 3-day free trial for eligible new subscribers. Prices are in US dollars; the App Store shows the price in your local currency before you confirm. Payment is charged to your Apple ID at confirmation of purchase (for the yearly trial, when the trial ends). The subscription renews automatically at the same price and period unless cancelled at least 24 hours before the end of the current period. Manage or cancel it anytime in your App Store account settings. Any unused portion of a free trial is forfeited when you purchase a subscription. Restore it on another device signed in with the same Apple ID with Restore Purchases.
Your files and DRM
DuoRead opens DRM-free files only. You may import only books and documents that you own or otherwise have the right to read and copy onto your device. DuoRead does not remove, bypass or circumvent DRM; protected books, including most books bought in the Kindle Store, cannot be opened. You are responsible for the files you import and for keeping your own backups.
AI output
Explain, Translate and Summarize answers are generated by AI (Google Gemini, or Apple Intelligence on the device) and may be inaccurate, incomplete or miss context. Check them against the text before relying on them, especially translations. They are not professional, legal, medical or academic advice.
Acceptable use
Use the app lawfully and don't attempt to disrupt or reverse-engineer it.
Disclaimer
The app is provided "as is" without warranties. AI-generated content may be inaccurate; review it before relying on it.
