Privacy Policy
SIM Vault: Contacts Offline · MR IU PING CHUNG (IU PING CHUNG) · 26 October 2026
This policy applies to the Android app SIM Vault: Contacts Offline, package com.ithongkong.simcard2excel, published on Google Play by MR IU PING CHUNG (IU PING CHUNG). Contact greenmob2014@gmail.com for privacy and support. The Android app contains Google AdMob banner and interstitial advertising. Local contact storage and user-initiated transfers are separate from the technical information processed for advertising.
Contacts, snapshots and SIM information
When you grant contacts permission, the app can display, back up and restore the contacts you choose. Contact snapshots are stored in the app’s private storage on your device. The app does not send your contact names, phone numbers, email addresses or saved snapshots to MobPage or AdMob.
Android contact snapshots are excluded from system cloud backup and automatic device-transfer backup. Saved snapshot files do not have an additional app-level encryption layer at rest; Android’s private-storage and device security controls apply.
Phone permissions support the SIM and network-information screen. Available details depend on Android permissions and platform restrictions. The app’s own SIM-display code does not attach SIM-panel data to advertising requests. Advertising identifiers and technical device information are handled separately as described below.
Transfers and exported files you choose
When you start a transfer, the app connects directly to the other compatible device over a network connection or Bluetooth where supported. Transfer contents are encrypted between the devices using session keys. A six-digit code lets you compare the connection on both screens. We do not provide a cloud relay or store a copy of the transferred contacts.
Use a connection and receiving device you choose. The app does not enforce that every network address belongs to your home network. Exporting or importing vCard and CSV files uses the system file picker. Files you export, share or transfer are stored or handled at the destination you select, separately from the app’s local snapshots.
Advertising and technical data
The Android version requests Google AdMob banner and interstitial advertisements. The Google Mobile Ads SDK collects and shares technical information with Google and advertising partners for advertising, analytics and measurement, fraud prevention, security and service operation. Advertising uses an internet connection; the app is not free of advertising or advertising-related analytics.
This technical processing does not include uploading your saved contact snapshots to AdMob. Google’s advertising services process the information under their policies.
| Technical information | How it is used |
|---|---|
| IP address and approximate location | The advertising SDK receives the device IP address, which may be used to estimate general location. |
| Device or other identifiers | Advertising ID, app-set ID and other applicable technical identifiers support advertising, measurement and fraud prevention. |
| App and advertisement interactions | Information such as app launches, taps, advertisement impressions and interactions supports advertising and measurement. |
| Diagnostics and performance | App/SDK performance information, such as startup time, hangs and energy usage, supports analytics and service operation. |
Network security and privacy choices
Google Mobile Ads SDK technical data is transmitted using HTTPS/TLS. Device-to-device contact transfers use the app’s separate encrypted transfer protocol. Locally saved snapshots and exported copies are distinct from data in transit.
You can manage or reset/delete your advertising ID through the controls available in Android settings. Such controls do not necessarily stop every type of advertising-related technical processing. This policy does not claim that the current Android release provides an in-app advertising-consent form or an in-app privacy-options screen.
Retention and deletion
Delete snapshots inside the app, clear its storage or uninstall it to remove app-local copies. Copies that you have exported or transferred to another device remain at the destination until you remove them there. The app does not provide a MobPage account or a cloud contact-sync database.
Google advertising data is retained and managed under Google’s and its partners’ policies and controls. We do not have direct access to erase each copy held by those services. If you contact support, we receive the email address, message and information you choose to send and retain that correspondence as needed to respond and meet applicable obligations.
Changes and contact
We may update this policy when the app or its services change. The latest version and date are published on this page.
