隱私權政策

最後更新：2026 年 8 月 31 日

簡短版：你丟進工具的檔案不會離開你的電腦。我們會知道有多少人來過、看了哪幾頁，但不知道你是誰。

1. 在你的裝置上完成、我們看不到的部分

PDF 合併與拆分、圖片壓縮與轉檔、影音轉換、雜湊計算、QR 碼、EXIF 移除等工具，全部使用瀏覽器內的 JavaScript 與 WebAssembly 運算。檔案不會上傳、不經過我們的伺服器、也不會產生暫存副本。命理工具輸入的姓名與生日同樣只在瀏覽器內計算。

部分功能會把資料存在你自己瀏覽器的本機儲存區（localStorage），這些資料留在你的裝置上，我們讀不到：

lp_favorites、lp_recents、lp_history：收藏的工具、最近使用與最近的結果。
lp_profiles：命理工具的人物檔案（姓名、生日、性別）。
lp-theme、lp-lang：你選的深淺色主題與介面語言。

清除瀏覽器的網站資料即可全部刪除，不需要通知我們。

2. 我們確實會收集的資料

為了知道哪些工具有人用、哪些頁面沒人看得懂，我們使用兩套流量分析：

Google Analytics 4（評估 ID：G-6CQ2R97C88）：記錄頁面瀏覽與按鈕點擊之類的自訂事件。事件只記「哪一頁的哪個按鈕」，不會帶入你輸入的內容——不會有檔名、姓名、生日或計算結果。
Cloudflare Web Analytics：不使用 Cookie、不做跨站追蹤的流量統計。

伺服器另會產生標準的存取紀錄（IP 位址、瀏覽器識別字串、時間），用於防止濫用與診斷故障。

3. 廣告與 Cookie

本站以 Google AdSense（發佈商 ID：pub-3871874754099191）投放廣告，以支應網域與頻寬成本。關於這件事你應該知道：

Google 這類第三方供應商會使用 Cookie，依你先前造訪本站或其他網站的紀錄放送廣告。
Google 使用廣告 Cookie 是為了向使用者放送廣告；你可以在 Google 廣告設定中停用個人化廣告。
想一次退出多家供應商的個人化廣告，可前往 aboutads.info 或 Your Online Choices。
更完整的說明見 Google 如何處理來自使用其服務的網站或應用程式的資訊。

廣告一律放在內容底部、每頁一個，不會蓋住操作介面，也不會偽裝成工具的一部分。

4. 帳號與跨裝置同步（選用）

如果你選擇登入，本站使用 Firebase Authentication 與 Firestore 同步你的設定與收藏。此時我們會取得登入供應商提供的最少資訊（電子郵件與帳號識別碼），僅用於辨識帳號與同步資料。不登入也能使用全部工具。

5. 意見回饋表單

首頁的意見回饋表單送出時：

以 Cloudflare Turnstile 驗證你不是機器人，驗證過程會將你的 IP 位址提供給 Cloudflare。
你填的稱呼、Email 與內容會轉送到維護者的 Telegram 通知頻道，僅用於回覆你。稱呼與 Email 是選填。

6. 兒童隱私

本站不針對 13 歲以下兒童設計，也不會刻意收集其個人資料。若你認為有此情形，請來信告知，我們會刪除。

7. 你的權利

本地儲存與登入資料你都可以自行清除（清除瀏覽器資料、或在站上登出並刪除帳號資料）。若你位於歐盟或加州等地，享有查詢、更正、刪除、限制處理與資料可攜的權利；行使方式請透過聯絡頁與我們聯繫。

8. 政策變更

本政策如有修改，會更新本頁的「最後更新」日期。重大變更會一併記錄在開發筆記。

9. 聯絡我們

對本政策有任何疑問，請見聯絡頁，或直接寫信到 tatanoi115@gmail.com。

Privacy Policy

Last updated: 31 August 2026

The short version: files you put into these tools never leave your computer. We can see how many people visit and which pages they read, but not who you are.

1. What happens on your device, where we cannot see it

Merging and splitting PDFs, compressing and converting images, converting media, hashing, QR codes, EXIF stripping and the rest all run on JavaScript and WebAssembly inside your browser. Files are not uploaded, never pass through our servers, and no temporary copy is made. Names and birth dates entered into the metaphysics tools are likewise computed in the browser only.

Some features keep data in your browser's own local storage. It stays on your device and we cannot read it:

lp_favorites, lp_recents, lp_history: favourite tools, recently used tools, and recent results.
lp_profiles: saved profiles for the metaphysics tools (name, birth date, gender).
lp-theme, lp-lang: your chosen colour theme and interface language.

Clearing site data in your browser deletes all of it. You do not need to tell us.

2. What we do collect

To learn which tools get used and which pages confuse people, we run two analytics services:

Google Analytics 4 (measurement ID G-6CQ2R97C88): page views and custom events such as button clicks. An event records which button on which page and never carries what you typed — no filenames, names, birth dates or results.
Cloudflare Web Analytics: cookie-free traffic statistics with no cross-site tracking.

Standard server access logs (IP address, user-agent, timestamp) are also produced, and are used to prevent abuse and diagnose faults.

3. Advertising and cookies

This site carries Google AdSense advertising (publisher ID pub-3871874754099191) to cover domain and bandwidth costs. What you should know:

Third-party vendors, including Google, use cookies to serve ads based on your prior visits to this site or other sites.
Google's use of advertising cookies enables it to serve ads to users. You can opt out of personalised advertising in Google Ads Settings.
To opt out of personalised advertising from many vendors at once, visit aboutads.info or Your Online Choices.
Fuller detail is in How Google uses information from sites or apps that use our services.

Ads sit at the bottom of the content, one per page. They never cover the interface and are never disguised as part of a tool.

4. Accounts and sync (optional)

If you choose to sign in, the site uses Firebase Authentication and Firestore to sync your settings and favourites. In that case we receive the minimum your sign-in provider supplies (email address and an account identifier), used only to identify the account and sync data. Every tool works without signing in.

5. The feedback form

When you submit the feedback form on the homepage:

Cloudflare Turnstile checks you are not a bot; that check passes your IP address to Cloudflare.
The name, email and message you enter are forwarded to the maintainer's Telegram notification channel, used only to reply to you. Name and email are optional.

6. Children's privacy

This site is not directed at children under 13 and does not knowingly collect their personal data. If you believe otherwise, write to us and it will be deleted.

7. Your rights

You can clear local storage and sign-out/delete synced data yourself at any time. If you are in the EU, California or a comparable jurisdiction, you have rights of access, correction, deletion, restriction of processing and data portability; to exercise them, get in touch via the contact page.

8. Changes to this policy

If this policy changes, the "last updated" date above changes with it. Significant changes are also recorded in the development log.

9. Contact
