support@bitesbyteslab.com常见问题 / FAQ
如何导出和分享制作好的邮票？How do I export and share my stamps?
拍摄或选择已有照片制作完成后，点击底部的「保存」或「分享」按钮，即可将带齿孔质感的完整邮票高清图存入您的系统相册，或直接分享至微信、小红书、Instagram 等社交平台。
After capturing or crafting your stamp, tap the "Save" or "Share" button to export the high-res stamp with perforated edges directly to your iOS Photos or share to social media.
什么是「无损存档」功能？What is the "Lossless Archive" feature?
传统的相机会直接保存裁剪后的位图，这会导致画质损失且无法重新构图。方寸不仅保存最终邮票，还会完整保留高分辨率原始底片与精确的归一化裁切坐标。未来无论更换到何种超高清屏幕，应用都能无损、精准地重新重建与渲染你的每一枚邮票。
Instead of only saving a low-res cropped bitmap, Fangcun securely archives the full-resolution original negative along with normalized crop coordinates. This ensures pixel-perfect reconstruction at any display resolution in the future.
地图标记足迹是如何工作的？How do Map Markers work?
若您授权了位置权限，方寸会在按下快门的一刻记录当前的 GPS 地理坐标。在应用内的「集邮地图」视图中，所有包含位置信息的邮票都会像大头针一样钉在世界地图上，让每一次旅途足迹清晰可见。所有定位信息仅在本地解析与展示，绝不上传。
When location access is enabled, GPS coordinates are recorded at the exact moment of capture. In the app's Map view, your stamps are pinned across geographical locations. All location processing remains strictly on your device.
可以在无网络（离线/飞行模式）下使用吗？Can I use Fangcun offline?
完全可以。方寸是一款100% 离线优先的工具，无需任何网络连接即可顺畅使用相机取景、齿孔算法渲染、照片存档和浏览历史邮票。
Yes, absolutely. Fangcun is 100% offline-first. All camera viewfinders, procedural perforations, and archiving features run entirely without internet connection.
更换手机后如何恢复已购项目？How do I restore my purchases?
如果您更换了新 iPhone 或重新安装了应用，只需进入「设置」页面，点击「恢复购买 (Restore Purchases)」，应用将自动通过您的 Apple ID 同步已解锁的全部权益与滤镜礼包，无需重复付费。
If you upgrade your device or reinstall the app, navigate to Settings and tap "Restore Purchases". Your Apple ID will automatically sync all purchased features and packs with no extra charge.
