1. Service and license
LeafSail is a local ebook reader provided by Shenzhen Xiaodangjia Technology Co., Ltd. This page explains product usage and purchase rules. The app is licensed under Apple’s standard End User License Agreement (EULA); this page does not replace that agreement or limit mandatory consumer rights.
The app imports and reads TXT, DRM-free EPUB, and unencrypted PDF files locally. It does not provide an online bookstore, copyrighted-content downloads, or DRM removal. Format and layout compatibility depend on the app’s actual capabilities.
2. Content and responsible use
Only import or share books, covers, and notes you have the right to use. Respect copyright, privacy, and other lawful rights. Rights to original content and notes remain with their respective owners; importing does not transfer ownership to us.
Do not use the app to distribute unlawful content, bypass content protection, or infringe others’ rights. Included sample books are for trying the app. Third-party software licenses are available in the app’s About screen.
3. Free features and Pro
Basic reading is free. A one-time, non-consumable Pro purchase unlocks the advanced features listed on the purchase screen, such as custom covers, additional reading themes, and advanced reading settings. Review the current app version’s feature descriptions before purchasing. Features vary by file format: PDF preserves the original page layout and does not support every TXT or EPUB layout option.
Pro does not renew automatically. The price and currency shown by your App Store storefront and Apple’s confirmation screen apply. Regions can have independent prices. ‘Lifetime’ means the current non-consumable Pro entitlement has no subscription expiry; it is not a guarantee that software, operating-system compatibility, or service will continue indefinitely, and it does not automatically include future, separately sold products.
A purchase requires your confirmation in Apple’s system purchase flow. You may dismiss each automatic Pro recommendation without a purchase; a recommendation never charges you automatically. Pro owners do not receive automatic upgrade prompts.
4. Restoration, refunds, and entitlement changes
After changing devices or reinstalling, use the App Store account that made the purchase and choose ‘Restore purchases’ on the Pro screen. Restoration depends on a valid transaction from Apple and network availability. Pending purchases require Apple to complete the transaction. We do not operate developer accounts or transfer purchases between Apple accounts.
Request refunds through Apple’s Report a Problem service. Approval is subject to Apple’s rules and applicable law. A refunded or revoked purchase may disable Pro features without deleting imported books or notes. If an entitlement is not recognized, try restoring before contacting support.
5. Local storage and backups
The app provides no developer-operated cloud sync or server backup of your library. Retain original files and use system device backups and note exports as needed. Deleting the app, device damage, or storage loss without a backup may make data unrecoverable. A text notes export does not include full books, custom covers, or all preferences.
We work to improve compatibility and reliability but cannot guarantee every file can be parsed or every device will retain data. These statements do not exclude liability that applicable law prohibits excluding.
6. Privacy, changes, and contact
See our privacy policy for data handling. Changes to features or rules will be communicated through release notes and appropriate in-app notices. Changes requiring separate consent will be handled as required by law. Updating this page does not retroactively remove purchased entitlements.
For support or disputes, contact developer@typcb.cn. Apple’s standard EULA, App Store transaction rules, and applicable law determine licensing and transaction responsibilities. This page does not limit your right to complain to relevant authorities or seek legal remedies.
