3. How We Share Your Information
We do not sell your personal information. We may share your data with:
- Network Partners: Mobile network operators who provide roaming coverage in your destination regions
- Payment Processors: Secure payment service providers who process your transactions
- Service Providers: Third-party vendors who help us deliver services (email delivery, customer support, analytics)
- Legal Authorities: When required by law, court order, or to protect our legal rights

All third parties are contractually obligated to protect your information and use it only for specified purposes.
4. Data Retention
We retain your personal information for as long as necessary to:
- Provide ongoing services and customer support
- Comply with legal, tax, and accounting obligations
- Resolve disputes and enforce our agreements
- Maintain business records for operational purposes
We keep your personal information only as long as we need it for the purposes above, or as long as the law requires (accounting records, for example). The identity document and SIM card photographs sent for a number port-in are deleted on the shorter schedule set out under "Identity documents and number port-in (MNP)" below.
5. Data Security
We implement industry-standard security measures to protect your information:
- Encryption of data in transit and at rest using SSL/TLS protocols
- Secure payment processing through PCI-DSS compliant providers
- Access controls and authentication for internal systems
- We review our systems and access controls, and we use encryption in transit and at rest
- Keeping our software and accounts up to date and protected by two-factor authentication
While we take reasonable precautions, no method of transmission over the internet is 100% secure. We cannot guarantee absolute security of your data.
6. Your Privacy Rights
Depending on your location, you may have the following rights:
- Access: Request a copy of the personal information we hold about you
- Correction: Update or correct inaccurate personal information
- Deletion: Request deletion of your personal data (subject to legal retention requirements)
- Portability: Receive your data in a structured, machine-readable format
- Opt-Out: Unsubscribe from marketing communications at any time
- Restriction: Request limitation of processing in certain circumstances
- Objection: Object to processing based on legitimate interests
To exercise these rights, contact us at unclesim@unclesim.net with your request.
7. Cookies & Tracking Technologies
We use cookies and similar technologies to:
- Remember your preferences and settings
- Analyze website traffic and user behavior
- Deliver personalized content and advertisements
- Improve website functionality and performance
You can control cookie preferences through your browser settings. Note that disabling cookies may affect website functionality.
8. International Data Transfers
Your information may be transferred to and processed in regions outside your residence, including Hong Kong and regions where our network partners operate. We ensure appropriate safeguards are in place to protect your data in accordance with this Privacy Policy and applicable laws.
9. Children's Privacy
Our services are not intended for children. For a number port-in, a customer under 16 must also have an adult guardian complete the real-name registration. We do not knowingly collect personal information about children; if you believe we have, contact us and we will delete it.
10. Third-Party Links
Our website may contain links to third-party websites or services. We are not responsible for the privacy practices of these external sites. We encourage you to review their privacy policies before providing any personal information.
11. Changes to This Privacy Policy
We may update this Privacy Policy periodically to reflect changes in our practices, technology, or legal requirements. We will post the updated policy on this page with a revised effective date. Continued use of our services after changes constitutes acceptance of the updated policy.
Identity documents and number port-in (MNP)
When you buy a number port-in (MNP) service, Hong Kong law requires us to complete a real-name registration for the SIM card before your number can be ported. For that we collect your name, your Hong Kong Identity Card number (or passport details if you have no HKID), an image of that identity document, your mobile number and your current carrier, the ICCID of your SIM card and a photograph of that SIM card, your contact email address and your typed signature, together with the time of your submission and a fingerprint (hash) of the signed application form.
Everything you type on our intake page, and both photographs, are encrypted on your own device with our public key before they are sent, so the parties that host and move that data hold only unreadable ciphertext. Your application form is prepared from that ciphertext using a decryption key held in encrypted storage on equipment we control in Hong Kong, never stored with your application data, and used only to prepare and submit your application. The completed application is submitted to the Carrier's designated confidential mailbox for real-name registration. We never ask you to send identity documents through a messaging app such as WhatsApp.
We use it only to apply to LuckySIM (the Carrier) to port your number and provide the related mobile service, to complete the real-name registration required by Hong Kong law, to verify your identity, and to process and confirm your application. It is never used for direct marketing. Your data, including the identity document image, may be transferred to LuckySIM and its operator / network, and to the service providers we engage (cloud hosting and transactional email), strictly to process those purposes. The identity document is a statutory and essential requirement: if you cannot provide it, we cannot complete the real-name registration and your port-in application cannot proceed.
The photographs are never written to disk on our own equipment: they are unsealed in memory for only as long as it takes to prepare and send your application. The sealed copies in our application record are deleted once your real-name registration and port-in are confirmed, and in any event within 30 days if the application is not completed. The copy we send ourselves for the hand-over to the Carrier stays in our own mailbox until your port-in is confirmed and is then deleted. We keep the completed application form itself (your details, the plan, your consent record and the signed-form fingerprint) as the record of the port-in we carried out on your behalf, together with accounting records as required by tax law; we do not keep the photographs in that record. Our database provider keeps a point-in-time recovery window of up to seven days, after which a deleted record cannot be restored.
The full notice, with your access and correction rights, is at unclesim.net/pages/privacy-mnp.
身份證明文件與攜號轉台（MNP）
你購買攜號轉台（MNP）服務時，香港法例要求我們先為 SIM 卡完成實名登記才可辦理轉台。為此我們會收集：你的姓名；香港身份證號碼（如無身份證則為護照資料）；該身份證明文件的影像；你的流動電話號碼及現時電訊商；你 SIM 卡的 ICCID 及該 SIM 卡的相片；你的聯絡電郵；以及你輸入的簽名，連同遞交時間及已簽署申請表的雜湊值（指紋）。
你在收料頁輸入的所有資料及兩張相片，會先在你自己的裝置內以我們的公開金鑰加密才送出，因此寄存及傳送這些資料的一方只會持有無法解讀的密文。申請表由該密文以解密金鑰填寫；金鑰存放於加密儲存內、在我們香港控制的設備上，不會與你的申請資料一同存放，只用於準備及提交你的申請。完成的申請會送往網絡商指定作實名登記的保密郵箱。我們任何時候都不會要求你透過 WhatsApp 等即時通訊軟件傳送身份證明文件。
我們只會用你的資料向 LuckySIM（網絡商）申請攜號轉台及提供相關流動服務、按香港法例完成實名登記、核實你的身份，以及處理及確認你的申請；不會用於直接促銷。你的資料（包括身份證明文件影像）可能轉移予 LuckySIM 及其營運商／網絡，以及我們委託的服務提供者（雲端寄存及交易電郵），僅限於處理上述目的。身份證明文件屬法定必要要求：如你未能提供，我們無法完成實名登記，你的轉台申請亦不能繼續。
相片不會寫入我們自己設備的磁碟：我們只在記憶體內解密，時間僅限於準備及寄出你的申請所需。我們申請紀錄中的密封副本，會於你的實名登記及轉台確認後刪除，如申請最終未能完成則最遲 30 日內刪除。我們為交給網絡商而發給自己的副本，會留在我們自己的郵箱內，直至你的轉台確認後刪除。我們會保留已完成的申請表本身（你的資料、計劃、同意紀錄及已簽署表格指紋），作為我們代你辦理轉台的紀錄，並按稅務法例保留會計記錄；我們不會在該紀錄中保留相片。我們的資料庫供應商提供最多七日的時點還原窗，七日後已刪除的紀錄無法復原。

Acceptance
These terms and this Privacy Policy apply to every order placed on unclesim.net. By placing an order you confirm that you have read and accept them. Where your order includes a number port-in (MNP), the identity document and the real-name registration are required by Hong Kong law, and we collect nothing until you tick the collection statement on the intake page we send you. If you do not tick it, we cannot complete the real-name registration and your port-in cannot proceed; in that case write to unclesim@unclesim.net and we will cancel the port-in and refund it in full.
接受條款
本條款及本《私隱政策》適用於在 unclesim.net 的每一張訂單。閣下落單即表示已閱讀並接受本條款及本《私隱政策》。如訂單包含攜號轉台（MNP），身份證明文件及實名登記屬香港法例的要求；在你於我們發出的收料頁上剔選收集個人資料聲明之前，我們不會收集任何資料。如你沒有剔選，我們無法完成實名登記，你的轉台申請亦不能繼續；在此情況下請電郵 unclesim@unclesim.net，我們會取消該轉台服務並全額退款。
