PeraListahan is an offline utang (credit) and sales ledger for sari-sari store owners in the Philippines. This policy explains, in plain language, what happens to the information you enter into the app and what measurement data the app sends.
Short version: your listahan — customers, utang, payments and stock — stays on your own iPhone and is never uploaded by us. The app uses the Adjust measurement SDK to record app installs, sessions and in-app events with a device identifier. It does not use the advertising identifier (IDFA), does not track you across other apps or websites, and shows no ads.
The app stores only the information you type in yourself, on your device:
Customer names, optional phone numbers and optional notes
Ledger entries: cash sales, utang (credit) amounts, payments, adjustments, dates and item names
Inventory items: name, cost, selling price and stock quantity
Your store name
This information is saved in a file inside the app's private storage on your iPhone. It is not uploaded anywhere by the app.
The app includes the Adjust SDK (Adjust GmbH, Germany) to measure app installs, sessions and in-app events. This helps us understand whether the app works and which features are used. The SDK sends:
Device identifiers: the vendor identifier (IDFV) and the Adjust identifier (ADID) generated for this installation
Product interaction: app opens, sessions and in-app event names such as a completed registration or a submitted form
Technical data: app version, bundle identifier, device model, operating system version, language and approximate region derived from the network
These values are used for analytics and install measurement only. They are not used for advertising, are not linked to your name or phone number, and are not sold.
No advertising identifier (IDFA) is read and no App Tracking Transparency prompt is shown
No account, email address, phone number or password is required to use the ledger
No advertising SDK and no ad network is included
The ledger features do not request access to contacts, location, photos, camera, microphone or notifications
No listahan content (customer names, amounts, notes) is ever sent to Adjust or to us
The ledger works fully offline. The app uses the network only to load its configuration and to send the measurement data described in section 2. Your customer records never leave the device.
The app can create a JSON backup file when you choose “Prepare backup file” and then share it with the iOS share sheet. That file is created only on your instruction, and it goes only to the destination you pick (for example Files or iCloud Drive). You control that copy.
When you tap “Share listahan”, the app prepares a plain-text summary of that customer's balance and recent entries and passes it to the iOS share sheet. Nothing is sent automatically.
Your ledger data stays on the device until you delete it
You can erase all customers, entries and items at any time from More → Erase all data
Deleting the app from your iPhone removes the app's local database
Measurement data is retained by Adjust according to its retention settings; see Adjust's privacy policy for details
Backup files that you shared are not controlled by the app; delete them from Files or iCloud Drive yourself
The only third party that receives data from the app is Adjust GmbH, which acts as our measurement processor and is bound by a data processing agreement. We do not sell data and we do not share it with advertisers or data brokers.
