为什么又做了个小程序Why a mini program too
手边只有手机的时候When only the phone is at hand
群里收到的 PDF 要合一下、报名表要压到 2MB 以内——这时候开电脑太慢，小程序点开就能改。A PDF from a group chat needs merging, a form has to fit under 2MB — opening a laptop is too slow. Open the mini program and it is done.
文件留在手机上Files stay on the phone
和网页版一样，能就地处理的就不往服务器送。没有上传进度条，也没有"处理中，请稍候"。Just like the browser version, whatever can be done in place never goes to a server. No upload bar, no "processing, please wait".
不用装 App，不用注册No app, no account
微信里搜一下就能用，用完退出即可。没有账号体系，也就没有东西可以被收集。Search once inside WeChat and it works. Close it when you are done — no account system means nothing to collect.
装进去的 28 个工具The 28 tools inside
和网页版同一套思路，换到了微信里。网页版更全，多了几个桌面端才顺手的工具。The same idea, living inside WeChat. The browser version is a bit fuller, with a few tools that only feel right on a desktop.

文件不上传，是我们唯一的卖点Nothing uploaded — that is the whole selling point
照片、票据、还没签的合同，本来就不该为了「处理一下」而先离开你的手机。密匣工具能做在本地做的，就在本地做；没有账号，没有云端相册，也没有把你的文件拿去训练什么。Photos, receipts, unsigned contracts should never have to leave your phone just to be “processed”. Whatever can be done locally is done locally: no account, no cloud album, and your files are not taken away to train anything.
