App name: Cek NPWP & KPP Offline / NPWP & KPP Checker Offline (com.htd.ceknpwp)
This privacy policy explains how we handle user information in our app “Cek NPWP & KPP Offline” (English title “NPWP & KPP Checker Offline”). We respect your privacy and are committed to protecting it. This app explains the structure of Indonesian taxpayer identification numbers (NPWP), including the 15-digit format, the 16-digit format, the NIK used as an individual NPWP and the 22-digit business location number (NITKU), and provides a list of Indonesian tax office (KPP) codes.
We DO NOT collect, store, or transmit the numbers you enter. When you type a number, it is decoded locally on your device and the result is only shown on your screen. The app has no search history, no accounts and no servers, and we do not collect personal data such as names, contacts, photos or location. The app does not use the camera.
The app does not connect to any government database (including the Directorate General of Taxes, DJP Online, Coretax or the population database of Dukcapil) and does not look up the owner, status or records of any number.
The only thing the app saves on your device is a small setting that records that you accepted the notice shown at first launch.
Our app uses Google AdMob to display ads, including banner, interstitial and app open ads. AdMob requires an internet connection. Google may collect and use certain data to serve and measure ads, such as your device's advertising ID, IP address, device and app information, and ad interaction data. Whether ads are personalised depends on your device settings. You can reset your advertising ID or opt out of ads personalisation in your Android settings (Settings > Google > Ads).
Please refer to Google’s privacy policy: https://policies.google.com/privacy
The app contains links that open official government websites (such as pajak.go.id) in your web browser. The app does not send any number to these websites. Anything you do on them is governed by the privacy policies of their operators.
This app is designed for general audiences. We do not knowingly collect personal data from children under 13. If you believe a child has provided us with personal data, please contact us.
Since we do not collect or transmit the numbers you enter or any other personal data, there is no personal data stored on any external server of ours that could be breached. The data you input never leaves your device through this app. Ad-related data is handled by Google according to its policies.
This app only requires access to the Internet (INTERNET and ACCESS_NETWORK_STATE) for the purpose of loading Google AdMob ads. The Google Mobile Ads SDK may also declare advertising-related permissions (for example AD_ID). Decoding numbers does not require any permissions and works without an internet connection.
The meaning of the digits and the tax office list are based on the following publicly available regulations and information. We do not own, operate or control these sources.
A correctly structured number is not necessarily a registered or active number. The tax office code shows the office at the time the number was created, and office names and working areas may change. We do not guarantee that any information is accurate, complete or up to date. The records of the Directorate General of Taxes always prevail. If you believe any information is wrong, please contact us (see below) and we will review it.
This application is an independent reference tool and is NOT affiliated with, endorsed by, or connected to the Directorate General of Taxes (Direktorat Jenderal Pajak, DJP), the Ministry of Finance of the Republic of Indonesia, the Directorate General of Population and Civil Registration (Dukcapil), or any other government agency. It does not represent any government entity.
Taxpayer numbers and NIKs contain personal or business information. Please only check numbers you are entitled to check, and do not use the app or its results to impersonate anyone, to commit fraud, or to harm others. The developer accepts no liability for the use or misuse of the app or its results.
We may update this Privacy Policy occasionally. When we do, we will revise the “Last updated” date at the top of this document. We recommend reviewing this policy periodically.
