Sandouk — Privacy Policy

Effective 6 October 2026. App: Sandouk — Building Fees (package com.gwhyyy.sandouk), published by Gwhyyy.

Summary

Sandouk works fully offline. We collect nothing, transmit nothing, and operate no servers, accounts, ads, or analytics. Your records stay on your device and leave it only when you choose to share, print, or export them.

Data stored on your device

Sandouk stores the records you enter — building details, apartment numbers and monthly amounts, resident names and contact details you add, monthly charge snapshots, and payment records (amount, date, method, reference, notes) — in a local database on your device. This data is never sent to us or any third party by the app.

Data you choose to share

PDF/CSV reports, payment receipts, printed documents, and JSON backups leave the app only when you explicitly use the share, print, export, or backup features. Those files can contain personal and financial information. Once shared, the receiving app or person controls that copy — share only with parties you trust.

Backups

Android cloud backup is disabled for Sandouk. The in-app JSON backup is the portable copy of your data; keep it somewhere safe. Restoring a backup replaces all current local data on the device.

Retention and deletion

Records remain on your device until you delete them (archive/delete actions in the app) or uninstall the app, which removes all app data. Monthly charge snapshots preserve resident names for ledger history even if a resident is later renamed or deleted.

Security

App data is protected by the Android app sandbox and your device's own security (screen lock, encryption). Exported files are plain readable files — store and share them carefully.

Children

Sandouk is a professional tool for building managers, landlords, syndics, and treasurers. It is not directed at children, and we knowingly collect no data from anyone, children included.

Permissions

Sandouk requests no dangerous permissions and has no internet access. File access occurs only when you pick a backup file to restore or when the system share sheet you invoked saves a file.

Changes to this policy

If this policy changes, the updated version will be posted at this URL and inside the app (Settings → Privacy policy) with a new effective date.
