Privacy Policy — Best Property Sale

Last updated: August 12, 2026

This Privacy Policy describes how Chief Bank ("we," "us," "our") collects, uses, and protects information through the Best Property Sale mobile application ("the App"), available on Android and iOS.

1. Who this policy covers

The App is used by:

• Approved Users, who register and sign in with a User ID
• General members of the public, who may browse listings as a Guest without creating an account or providing any personal information

2. Information we collect

From Approved User accounts (registration and profile)

• Name
• Email address
• Phone number
• Date of birth
• User ID (used to log in)

When creating a listing

• Photos of the listed asset/property
• Listing location (precise and approximate — set on a map when creating a listing)
• Contact details for the listing (name, phone number, and optionally email, Telegram ID, Facebook ID, or Microsoft Teams contact)
• Listing title and description

Automatically, for all users (including Guests)

• App interaction data — which features are used, to understand how the app is used and improve it
• Crash logs and diagnostics — to identify and fix bugs and stability issues
• Device identifiers — including a push-notification token and a device identifier used for app security (detecting tampered or compromised devices)

We do not collect: precise contact-list data, SMS/calendar data, health data, or any advertising identifier. The App does not show ads and does not use the Android/iOS advertising ID.

3. How we use this information

Purpose	What it's used for
Account management	Creating and managing Approved User accounts, logging in, verifying credentials
App functionality	Enabling listing creation, showing listing locations on a map, contacting a listing owner, push notifications
Analytics	Understanding feature usage and app performance, so we can improve the App
Fraud prevention and security	Detecting tampered devices and protecting accounts

4. Sharing of information

We do not sell or share your personal information with third parties for their own marketing or advertising purposes.

Some data is processed by Firebase (a Google service) — specifically Firebase Analytics, Crashlytics, and Cloud Messaging — acting as our service provider, solely to provide app analytics, crash reporting, and push notifications on our behalf. Firebase does not use this data for its own independent purposes.

5. Guest mode

Anyone can browse listings in the App without creating an account, providing a name, email, or any other personal information, by choosing "Continue as Guest." Guest use still generates the automatic app-interaction, crash, and device-security data described in Section 2, in the same way as it would for any user of the App.

6. Data security

All data sent between the App and our servers is encrypted in transit (HTTPS/TLS). The App also uses certificate pinning and on-device integrity checks to help detect tampered devices and protect your account.

7. Data retention and account deletion

We retain your account information for as long as your account remains active.

We will delete or anonymize your personal information within 30 days, except where we are required to retain certain records for longer to comply with applicable banking, financial, or legal record-keeping obligations. Records retained in this way no longer identify you.

If you no longer have the App installed, you can request deletion instead. Full details are on our Account Deletion page.

8. Your rights

• Review and update your profile information within the App (Profile > Edit Profile)
• Delete your account and associated data at any time from within the App (Profile > Edit Profile > Delete Account), or see our Account Deletion page if you no longer have the App installed
• Contact us with any privacy questions or requests at the details below

9. Children's privacy

The App is intended for use by adults (18 and over) who are Approved Users, or members of the public browsing as a Guest. It is not directed at children, and registration as an Approved User requires a valid User ID.

10. Changes to this policy

We may update this Privacy Policy from time to time. Material changes will be reflected by updating the "Last updated" date above.
