Privacy Policy

SJI Tech values your trust. This Privacy Policy details our absolute commitment to user privacy, offline data preservation, and strict security across our site and mobile applications.

Last Updated: November 12, 2026

1. General Web Privacy

The SJI Tech website (sjitech.uk) does not run any marketing, tracking, or analytical cookie scripts. If you submit our contact form, the provided details (Name, Email, Phone, Message) are saved securely on our servers solely to handle your technical contract inquiry and are never shared or sold to third parties.

2. Mobile Applications Privacy Disclosure

This section applies specifically to our mobile products listed on the Google Play Store and Apple App Store:

  • PrayerTimes Masjid Display
  • Quran Tajweed
  • Zakat Management
  • Badminton Court Manager
  • File Date(Timestamp) Fixer
  • Mobile As Security Camera

A. 100% Offline Nature

Our applications are designed with an "Offline-First" architecture. All application texts, database records, calculations, and assets are stored natively in secure, on-device SQLite databases. They execute completely without internet connectivity (except for downloading optional audio assets or streaming, which connects directly to primary CDNs).

B. Zero Data Collection & Sharing

We do not collect, monitor, store, or transmit any user financial logs, search histories, bookmarks, voice notes, files, or location details. Everything remains exclusively on your device. We use zero tracking SDKs, advertising APIs, or analytical frameworks.

C. Device Permissions Breakdown

We request device permissions strictly to run local calculations or operations. These permissions can be disabled in your OS Settings at any time:

  • Location Access: Used strictly on-device in PrayerTimes, Quran Tajweed, and Zakat Management to calculate accurate astronomical prayer times and local Qibla direction based on the device's geomagnetic heading. It is never transmitted outside your physical device.
  • Microphone Access: Used in Quran Tajweed strictly to record optional voice notes on verses. They are saved directly inside your device's sandbox.
  • Storage / Files Access: Used in Zakat Management, PrayerTimes, and File Date Fixer to import/export backup zip archives or parse filesystem files.
  • Camera Access: Used in Mobile As Security Camera strictly to broadcast local frames to your authenticated client devices.

D. Financial & Personal Security

In our Zakat Management application, all input values—including cash balances, gold weights, asset valuations, and personal profile ledgers—are stored strictly locally. Users have the option to set a local password or PIN lock, which hashes details on-device using secure PBKDF2/SHA-256 algorithms. No cloud backup syncs exist unless performed manually by exporting a local encrypted archive.

3. Policy Changes

We may update our Privacy Policy periodically. Since our applications do not connect to external servers, we encourage you to review this page on sjitech.uk to stay updated on our security guidelines.
