合同、报价单、成绩单、病历——这些东西不该躺在别人的云端。墨鱼PDF 的处理逻辑从一开始就是「阅后即焚」：Contracts, quotes, transcripts, records — these shouldn't sit on someone's cloud. MoyuPDF was built "burn-after-reading" from day one:
「下午三点的活，—— 墨鱼PDF 用户的真实下午— a real afternoon, MoyuPDF user
两分钟干完——
剩下的时间，是摸鱼送你的。」"A 3 p.m. task,
done in two minutes —
the rest of the day is yours."
