大拇指私隱協議

最後更新:2026年7月31日

本私隱協議適用於大拇指(Thumbmasters)提供的「大拇指用戶端」「大拇指師傅端」流動應用程式及配套管理服務。

請在使用服務前閱讀並理解本協議。如您不同意本協議內容,請停止註冊、登入或使用相關服務。

一、資料使用者

本服務的資料使用者為冰山數據(香港)有限公司,地址為香港九龍尖沙咀東部科學館道 14 號新文華中心 A 座 720 室。我們會按照香港適用法例(包括《個人資料(私隱)條例》(第 486 章))處理個人資料。

二、我們收集的資料

三、權限及本機存取

應用程式需要連線以完成註冊、登入、訂單同步、節點匯報、檔案上載和訊息互動。應用程式不申請 Android 精確位置權限;如您自願填寫項目地址或問題位置,該文字僅用於提供裝修、驗收和售後服務。

當您選擇上載圖片、影片、證書或付款憑證時,應用程式會開啟系統檔案選擇器,並僅上載您選擇的檔案。

四、資料用途

五、資料共享

我們不會出售您的個人資料。為完成裝修服務,我們可能在必要範圍內向訂單相關方展示去識別化後的姓名、角色、訂單狀態、節點進度、驗收結果和經審核後可見的施工材料。

我們可能委託短訊服務、雲端儲存、伺服器託管、資料備份、錯誤監控等服務提供者處理必要資料。服務提供者只能按我們的指示處理資料,並應承擔保密和安全保護義務。

只有在您明確同意崩潰診斷且平台診斷上載總開關開啟時,我們才使用 Sentry 處理上述診斷資料,資料儲存位置選用德國的歐盟資料區域。您可以查看 Sentry 私隱政策了解其資料處理安排。

在適用法例、監管要求、司法程序或保障用戶、師傅與平台合法權利及權益所必需時,我們可能依法披露必要資料。

六、資料保留及保障

我們只會在達成本協議所述目的所需期間保留個人資料,並採取存取權限管制、傳輸加密、權限隔離、操作紀錄和後台審核等措施保障資料安全。

帳號刪除完成後,帳號資料、登入憑證、工作階段憑證和不再需要的個人資料會在完成身份核實後 15 個工作日內刪除或匿名化。訂單、付款、結算、保養、售後、爭議處理和保安審計相關紀錄,可能因遵守法例、履行合約、財務審計或解決爭議而保留最長 7 年;法例另有要求或爭議仍在處理的情況除外。

七、您的權利

您可以要求查閱及更正您的個人資料,亦可按服務流程申請刪除帳號及不再需要保留的個人資料。帳號刪除申請入口為:

App 內:登入後進入「帳號與安全」→「刪除帳號」。

網頁端:網頁端帳號刪除申請入口

首次啟動且您尚未作出選擇時,App 會在正常應用程式介面上以獨立彈出視窗詢問是否同意崩潰診斷。您可以選擇同意或不同意;不同意不影響正常使用。已作出選擇後,App 不會因平台開關關閉或重新開啟而再次顯示授權視窗。

您可以隨時在 App 內進入「帳號與安全」→「崩潰診斷」關閉開關並撤回同意。關閉後,App 會立即停止後續診斷資料的收集和上載;重新開啟即表示您再次同意,但實際上載仍須平台診斷上載總開關同時開啟。更改此設定不會再次顯示首次授權視窗。

平台另設診斷上載總開關,同時控制用戶端、師傅端、iOS 和 Android,App 會在每次完全重新啟動時讀取其狀態。只有 App 內的崩潰診斷開關和平台總開關同時開啟時,App 才會上載診斷資料。您在 App 內關閉開關後,不論平台開關狀態如何均不會上載;平台總開關關閉或 App 無法讀取其狀態時,該次啟動也不會上載診斷資料。平台總開關不會修改或覆蓋您的選擇。

平台日後重新開啟總開關時,您先前的選擇仍然有效:App 內開關保持開啟者可在下一次完全重新啟動後恢復診斷上載,已關閉者仍不會上載。如需要求刪除已上載的相關診斷資料,請透過下方電郵聯絡我們。

您也可以透過電郵聯絡我們:thumbmasterdev@gmail.com

八、未成年人私隱

我們的服務對象為成年裝修客戶和服務人員,不以未成年人為服務對象。若您認為未成年人向我們提供了個人資料,請透過本協議中的聯絡方式通知我們。

九、協議更新

我們可能根據服務變化或法律要求更新本私隱協議。更新後會在本頁面公布新的生效日期。

十、聯絡我們

如對本私隱協議、個人資料保障或帳號刪除有任何問題,請電郵至 thumbmasterdev@gmail.com

Thumbmasters Privacy Policy

Last updated: July 31, 2026

This Privacy Policy applies to the Thumbmasters Customer App, Thumbmasters Worker App, and the related administration services provided by Thumbmasters.

Please read and understand this policy before using our services. If you do not agree with it, stop registering, signing in to, or using the services.

1. Data User

The data user for these services is ICEBERG DATA (HONG KONG) LIMITED, of Suite 720, Tower A, New Mandarin Plaza, 14 Science Museum Road, Tsim Sha Tsui East, Kowloon, Hong Kong. We process personal data in accordance with applicable Hong Kong law, including the Personal Data (Privacy) Ordinance (Cap. 486).

2. Information We Collect

3. Permissions and Local Access

The apps require network access for registration, sign-in, order synchronization, node reports, file uploads, and messaging. They do not request Android precise-location permission. Project addresses and issue locations that you enter are used only to provide renovation, acceptance, and after-sales services.

When you upload an image, video, certificate, or payment receipt, the app uses the system file picker and uploads only the files you select.

4. How We Use Information

5. Information Sharing

We do not sell your personal information. To deliver renovation services, we may show order participants the minimum necessary de-identified names, roles, order status, node progress, acceptance results, and administrator-approved work materials.

We may use service providers for SMS delivery, cloud storage, server hosting, backups, and error monitoring. They may process data only under our instructions and must protect its confidentiality and security.

Only when you have expressly consented to crash diagnostics and the platform-wide diagnostic-upload switch is on do we use Sentry to process the diagnostic information described above, with data stored in Sentry's EU data region in Germany. See the Sentry Privacy Policy for details about its data-processing practices.

We may disclose necessary information when required by law, regulation, legal process, or to protect the lawful rights and interests of customers, workers, or the platform.

6. Retention and Security

We retain personal information only as long as needed for the purposes described in this policy. We use access controls, encryption in transit, permission isolation, operation logs, and administrator review to protect data.

After account deletion is completed, account data, sign-in credentials, session tokens, and personal data that is no longer required will be deleted or anonymized within 15 business days after identity verification. Order, payment, settlement, warranty, after-sales, dispute, and security-audit records may be retained for up to seven years where required for legal compliance, contract performance, financial audit, or dispute resolution, unless the law requires longer retention or a dispute remains active.

7. Your Rights

You may request access to, correction of, or deletion of your personal information. You may also submit an Account deletion request here:

In the App: sign in, then go to “Account & security” → “Delete account”.

On the web: Web account deletion request

On the first run for which you have not yet made a choice, the App displays a separate consent dialog over the normal app interface. You may allow or decline crash diagnostics, and declining does not affect normal app use. After you make a choice, turning the platform switch off or on again does not display the consent dialog again.

You may withdraw consent at any time in the App by going to “Account & security” → “Crash diagnostics” and turning the switch off. The App then immediately stops collecting and uploading new diagnostic information. Turning it on again records your renewed consent, but uploads still require the platform-wide diagnostic-upload switch to be on. Changing this setting does not display the first-run consent dialog again.

The platform also has one diagnostic-upload switch for the Customer App, Worker App, iOS, and Android, and the App checks its status on every cold start. Diagnostic data is uploaded only when both the in-App Crash diagnostics switch and the platform switch are on. After you turn the in-App switch off, no diagnostic data is uploaded regardless of the platform switch. Upload is also not enabled for that run when the platform switch is off or the App cannot retrieve its status. The platform switch does not change or override your choice.

If the platform later turns its switch on again, your previous choice remains effective: upload may resume after the next cold start when the in-App switch remains on, while users who turned it off still do not upload diagnostic data. To request deletion of related diagnostic information already uploaded, contact us at the email address below.

You may also contact us by email at thumbmasterdev@gmail.com.

8. Children

Our services are intended for renovation customers and service personnel with legal capacity and are not directed to children. If you believe a child has provided personal information to us, contact us using the details in this policy.

9. Policy Updates

We may update this Privacy Policy when our services or legal obligations change. The updated effective date will be published on this page.

10. Contact Us
