About Daily Office Tools
A privacy-first collection of browser-based productivity utilities.
What the website provides
The site combines PDF utilities, image processing, text cleanup, data conversion, calculators, generators, and simple productivity tools in one consistent interface.
Why static?
A static architecture is fast to deploy, inexpensive to host, easy to audit, and suitable for tools that do not require accounts or databases. Most tools use standard browser APIs such as Canvas, FileReader, Web Crypto, and Local Storage.
Languages
The default language is English, with Traditional Chinese available from the language switch in the header.
Who runs this site
Daily Office Tools is published by Long-Term New Media Limited. The site is maintained as a single static codebase with no user accounts, no server-side processing and no database, which is what makes the privacy claim on every tool page verifiable rather than promissory: there is no server to receive your files. Questions, corrections and tool requests reach a person at the contact page.
How the tools are chosen
Each tool exists because the job it does is common, small enough to finish in one screen, and awkward to do otherwise — either because the obvious alternative wants an upload, an account or a subscription, or because it means opening a heavyweight application for thirty seconds of work. Tools that would need a server to work properly, such as optical character recognition or anything requiring a licensed font or codec, are deliberately left out rather than shipped in a form that disappoints.
What we do not do
No file you open is uploaded, no analytics profile is built, and there is no newsletter capture, account wall or trial period. The site stores exactly three things in your browser: your language choice, and the contents of the local notes and to-do tools if you use them. All three stay on your device and are cleared when you clear site data.
Accuracy and limitations
The calculators implement standard, published formulas and the converters use standard definitions, but results depend on the values you enter and on assumptions that vary by country and contract — tax rates, overtime thresholds, depreciation methods and working-week conventions among them. For financial, tax, legal or payroll decisions, treat the output as a check on your own reasoning rather than as advice, and confirm against the rules that apply where you are.
網站提供的內容
網站將 PDF、圖片處理、文字清理、資料轉換、計算器、產生器與日常效率工具整合在同一套一致的介面中。
為什麼採用靜態網站？
靜態架構部署速度快、託管成本低、容易檢查，也適合不需要帳號與資料庫的工具。多數功能使用 Canvas、FileReader、Web Crypto 與 Local Storage 等瀏覽器標準能力。
語言
網站預設使用英文，並可透過頂部語言切換器切換為繁體中文。
網站營運者
Daily Office Tools 由 Long-Term New Media Limited 發行，以單一靜態程式庫維護，沒有使用者帳號、沒有伺服器端處理，也沒有資料庫。這正是每個工具頁上的隱私說明可被驗證、而非空口承諾的原因：根本沒有一台伺服器會收到你的檔案。有問題、指正或希望新增工具，請透過聯絡頁面與我們聯繫。
工具怎麼挑選
每個工具會存在，是因為它處理的事情夠常見、一個畫面內能完成，而且用其他方式做起來很彆扭——不是因為現成替代方案要求上傳、註冊或訂閱，就是因為得為三十秒的工作開啟一套笨重的軟體。至於必須靠伺服器才能做好的功能，例如光學文字辨識，或需要授權字型與編解碼器的處理，我們寧可不做，也不願交出一個讓人失望的版本。
我們不做的事
你開啟的檔案不會被上傳、不會建立分析輪廓，也沒有電子報蒐集、帳號牆或試用期。網站只在你的瀏覽器裡存三樣東西：語言選擇，以及本機記事本與待辦清單的內容（如果你有使用）。這三者都留在你的裝置上，清除網站資料時就會一併消失。
準確度與限制
計算器採用公開的標準公式，換算器使用標準定義，但結果取決於你輸入的數值，也取決於各國與各份合約不同的前提——稅率、加班門檻、折舊方法與每週工時慣例都在其中。涉及財務、稅務、法律或薪資的決定，請把輸出當成驗算自己判斷的工具，而不是專業建議，並依你所在地區的實際規定再確認一次。
