把"隐私"做成了出厂设置Privacy, by default
不联网、本地加密、数据完全自主——每一项都为"钱只属于你"而设计。No network, local encryption, full data ownership — every feature exists so your money stays yours.
真正离线，隐私零外泄Truly offline
应用不申请任何联网权限，所有数据只存在你手机本地，不上云、不追踪、不上传统计。断网也能完整使用。No network permission at all. Everything stays on your device — no cloud, no tracking, no analytics. Works fully offline.
本地加密存储Local encryption
数据库采用 SQLCipher 加密，密钥保存在本机。即便手机丢失，账本文件也无法被直接读取。The database is encrypted with SQLCipher; the key lives on your device. A lost phone won't expose your ledger.
多账本自由管理Multiple ledgers
家庭账、生意账、旅行账、装修账……多个账本分开记、独立分类与统计，互不干扰。Family, business, trip, renovation — keep separate ledgers with independent categories and stats.
模板记账，秒完成Templates
常用收支存为模板，下次一键套用；支持从银行流水 / 通用 CSV 批量导入，告别逐笔录入。Save frequent entries as templates and apply in one tap; bulk-import from bank statements or CSV.
预算与统计Budgets & stats
日历视图、趋势图、分类汇总多维看懂收支；可设月度预算，超支早知道。Calendar, trends and category breakdowns show where money goes; set monthly budgets and get overspend alerts.
应用锁 + 隐私遮罩App lock & mask
支持 PIN 码与指纹解锁；切到后台或进入多任务卡片时自动遮挡界面，防偷窥。PIN and fingerprint unlock; the screen auto-masks in the app switcher to block shoulder-surfing.
你的数据，只属于你Your data belongs to you
我们把"不联网"从一句口号，做成了系统层面无法绕过的现实。We turned "no network" from a slogan into a system-level guarantee you can verify yourself.
零联网权限Zero network
安装所需权限仅 5 项基础权限，无任何 INTERNET 权限——从系统层面杜绝后台上传。Only 5 basic permissions, with no INTERNET permission at all — nothing can upload in the background.
本地加密Local encryption
SQLCipher 加密数据库，密钥留在本机，文件级保护——丢了手机也读不到账本。SQLCipher-encrypted database with the key on your device; file-level protection if the phone is lost.
应用锁App lock
PIN + 指纹解锁（基于 Android 强生物识别），离开即锁，可靠不降级。PIN plus fingerprint (Android strong biometrics) — locks the moment you leave.
多任务遮罩Task mask
离开 App 时界面自动遮挡，保护后台卡片不被偷看、防侧录。The screen auto-masks when you leave the app, hiding it from the recent-apps view.
不绑定账号、不强推云端、数据自主——本地备份、换机导出、随时删除，全由你说了算。No account, no forced cloud, data autonomy — local backup, device migration, delete anytime. All your call.
说明：多任务遮罩为"尽力遮挡"，不承诺在所有机型 100% 拦截系统截图缩略图；生物识别仅承诺指纹。Note: the task mask is best-effort and not guaranteed on every device; biometrics promise fingerprint only.
跟着系统，八语随心Eight languages, auto
支持 8 种语言，自动随系统切换，也可在 App 内手动指定。繁体中文界面品牌名显示为「記賬庫」。Eight languages that follow your system automatically, or pick one in-app. Traditional Chinese shows the name 記賬庫.
