Revision History

1. Introduction

This Privacy Policy describes how Sia Makerlab ("we," "us," or "our") collects, uses, and shares information in connection with your use of the QueryDock for MS-SQL Server mobile application (the "App").

The App is an Android client for querying and managing remote Microsoft SQL Server databases (SQL Server 2016 through 2025) that you specify. It connects directly from your device to the database servers you configure. It does not require you to create an account, and we do not operate a server that stores your connection details or your data. By downloading, installing, or using the App, you agree to the collection and use of information in accordance with this Privacy Policy. If you do not agree, please do not use the App.

2. Information We Collect

2.1 Information You Provide

The App is designed to function without an account or personal information. We do not collect your name, email address, phone number, or physical address.

To connect to a database, you provide its details — a connection name, host/port/instance, database name, authentication credentials (SQL authentication), encryption and certificate options, and optional SSH tunnel settings. This configuration is stored locally on your device and is not collected by us.

2.2 Connections You Configure (Outbound Requests)

When you open a connection, the App communicates directly from your device to the Microsoft SQL Server you specified over JDBC. Your queries and their results travel between your device and that server — not through us. We do not see, receive, or store your servers, credentials, queries, or data. You are responsible for ensuring you are authorized to access any server you connect to.

If you choose to use Microsoft Entra sign-in, the App contacts Microsoft identity endpoints directly from your device to authenticate you. This is initiated by you, and that exchange is governed by Microsoft's terms and privacy policy (see Section 4.2). We are not a party to it and do not receive your Microsoft credentials or tokens.

2.3 Information Stored on Your Device

The App stores the following data only on your device:

This data is stored exclusively on your device. We do not have access to it, and it is never transmitted to our servers.

2.4 Biometric App Lock

If you enable the biometric app lock, authentication is performed by the Android operating system on your device. The App never receives, stores, or transmits your fingerprint or other biometric data.

2.5 Permissions

• Internet (INTERNET): required to connect to the database servers you configure, to authenticate via Microsoft Entra if you choose it, and to serve ads.
• Network state (ACCESS_NETWORK_STATE): used to detect network availability.
• Biometric (USE_BIOMETRIC): used only if you enable the optional biometric app lock. You may decline it.
• Advertising ID (AD_ID): used by Google AdMob to serve ads (see Section 2.6).

The App does not request location, camera, microphone, or contacts permissions.

2.6 Advertising Data (Third-Party)

Unless you purchase the ad-removal option, the App displays advertising through Google AdMob (App Open and native formats; the App Open ad is shown at most once every 15 minutes). Our advertising partner may collect:

• Advertising ID (Android Advertising ID)
• Device information (device type, operating system version)
• IP address
• General location data (country/region level)
• Ad interaction data

Where required, the App uses Google's User Messaging Platform (UMP) to obtain your consent for personalized advertising. This data collection is governed by Google's Privacy Policy: https://policies.google.com/privacy

2.7 Information We Do NOT Collect

We explicitly do not collect:

• Personal or contact information
• Your servers, credentials, queries, or database contents
• Analytics or usage tracking data by us directly
• Precise location data
• Payment or card information (handled by Google Play)

3. How We Use Information

3.1 Local Data Usage

Data stored on your device is used locally to:

• Establish the connections you configure and run your queries
• Remember your connection profiles, history, and snippets
• Apply your settings, biometric app lock, and preferences
• Apply your ad-removal entitlement

3.2 Third-Party Data Usage

Data collected by Google AdMob and Google UMP is used to display personalized or non-personalized advertisements (based on your consent) and to prevent fraud and abuse. Data collected by Google Play Billing is used to process and reconcile your purchase.

4. Data Sharing and Disclosure

4.1 We Do Not Sell Your Data

We do not sell, trade, or rent your personal information to third parties.

4.2 Third-Party Service Providers

The App integrates the following third-party services, which handle data according to their own privacy policies:

Separately, the App communicates directly with the SQL Server databases you specify. Those servers are operated by you or by parties you choose, and their handling of your connections and data is outside our control.

4.3 Legal Requirements

We may disclose information if required to do so by law or in response to valid requests by public authorities. As we hold no user content, such disclosure would be limited to information actually in our possession.

5. Data Retention

5.1 Local Data

Data stored on your device remains until you delete it within the App, clear app data in device settings, or uninstall the App.

5.2 Third-Party Data

Data collected by Google's advertising, consent, and billing services, and by the Microsoft identity platform if you use Entra sign-in, is retained according to their respective policies.

6. Your Rights and Choices

6.1 For All Users

You have the right to:

• Access: View your data within the App
• Delete: Remove connection profiles in the App, or clear app data or uninstall the App to remove all local data
• Opt out of personalized ads: Manage ad personalization through your device's advertising settings or the UMP consent options

6.2 For Users in the EEA, United Kingdom, and Switzerland

Under the GDPR and applicable laws, you also have the rights to access, rectification, erasure, restriction of processing, data portability, objection, and withdrawal of consent. To exercise rights over data held by a third-party service, contact that service directly.

6.3 Managing Consent

Manage advertising consent through:

• In-App: privacy/consent options provided via Google UMP
• Device Settings: Android Settings > Google > Ads

7. Data Security

We implement reasonable technical measures to protect data on your device:

• Connection credentials are encrypted with the Android Keystore (AES/GCM)
• Data is stored only on your device; we operate no server and keep no copies
• No cloud synchronization and no user accounts
• Network access is used only to reach the servers you configure, to authenticate via Microsoft Entra if you choose it, and to serve third-party advertising

8. Children's Privacy

The App is not directed to children under the age of 13 (or 16 in the EEA). We do not knowingly collect personal information from children.

9. International Data Transfers

Data collected by third-party services may be transferred to and processed in countries with different data protection laws. Please refer to Google's and Microsoft's privacy policies for more information.
