CekinSaldo is an offline NFC card balance reader for Indonesian electronic money cards. This policy explains what data the app handles, what is processed and stored only on your device, and what Google AdMob may collect when it shows ads. No account is required to use CekinSaldo.
1. Data We Do Not Collect
We, the developer, do not operate a server that collects your card numbers, balances, or transaction history. CekinSaldo does not require you to create an account, sign in, or provide your name, email address, or location to use its core features. The app never asks for, and can never read, your card PIN, bank password, or any banking credential. We do not sell personal data.
2. Card Reading via NFC — On-Device Only
When you tap a supported card (such as Mandiri e-money, BCA Flazz, BRI Brizzi, BNI TapCash, KMT Multi Trip, Bank DKI JakCard, or JakLingko) against your phone, the app reads the card number, remaining balance, and — where the card supports it — recent transaction history directly from the card's chip using NFC. This reading happens entirely on your device. The data read from your card is not uploaded to a developer server or to any third party by the app. Reading is read-only: the app cannot top up, transfer, or change the balance stored on your card.
3. Data Stored Offline, On Your Device Only
If you choose to save a card in "My Cards," the card type, a masked card number, the label you give it, and its last known balance are stored solely in local storage on your device, together with your scan history. They are not uploaded to a developer server. If you uninstall the app or clear its storage, that local data is removed from your device.
4. Permissions
NFC permission is required for the app's core function: communicating with your card when you tap it to your phone. The app does not use NFC in the background to track cards or devices. Internet access is used only to load advertisements (see Section 5). The app's balance-checking features work fully offline.
5. Advertising — Google AdMob
CekinSaldo shows ads provided by Google AdMob. AdMob and its partners may collect device-related information, including the device Advertising ID and app diagnostics, to serve and measure ads, including for advertising, analytics, and fraud prevention. This collection is governed by Google's Privacy Policy: https://policies.google.com/privacy.
You can reset your Advertising ID or opt out of ads personalisation in your device settings (Settings > Privacy > Ads on Android).
6. Data Security and Transfer
Because your card data and scan history stay on your device, there is no developer-server transfer of that data to secure. Any data AdMob collects in connection with ads is transmitted over encrypted connections (HTTPS) by Google's services.
7. Data Deletion
Since we do not hold your card data on a server, there is no server-side account data for us to delete. To delete your app data, remove saved cards and scan history in the app, clear the app's storage in Android Settings, or uninstall CekinSaldo. To limit ad-related data, reset your Advertising ID in your device settings as described above.
8. Children
CekinSaldo is not directed to children under 13, and its store listing targets users aged 18 and older. We do not knowingly collect personal data from children.
9. Changes to This Policy
If this policy changes, the updated version will be posted at this URL and the effective date above will be updated. Continued use of CekinSaldo after a change means you accept the updated policy.
