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 MySQL & MariaDB mobile application (the "App").

The App is a native Android client that lets you connect to and manage remote MySQL and MariaDB servers of your choosing — browsing databases and tables, running queries, editing data, and managing users and privileges. It does not require you to create an account, and we do not operate a server that stores your connection profiles, credentials, or data. The App connects directly from your device to the database servers you specify. 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 server, you provide its details — a profile name, host, port, database, user, SSL/TLS mode, and the password required, plus optional SSH tunnel settings (host, port, user, and keys). This information is stored locally on your device and is not collected by us.

2.2 Connections You Configure (Outbound Requests)

When you connect to a server, the App sends requests directly from your device to the MySQL or MariaDB server you entered (optionally through an SSH tunnel you configure). These requests — including your queries, data edits, and DDL — go to the servers you specify, not to us. We do not see, receive, or store the servers you connect to, your credentials, your queries, or the data you read or write. You are responsible for ensuring you are authorized to access any server you add.

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 Import and Export

The App can export data to SQL, CSV, and JSON files, and import data from CSV files, using the Android file picker to choose the location. These files are read from and written to locations on your device or storage that you select. We do not access, receive, or store these files.

2.5 Home-Screen Widget

The App offers an optional home-screen widget. Any information shown by the widget is derived from data stored locally on your device and is not transmitted to us.

2.6 Biometric App Lock

You may optionally enable a biometric or device app lock. Verification is performed entirely by the Android system on your device. The App never receives, stores, or transmits your fingerprint or biometric data.

2.7 Permissions

• Internet (INTERNET): required to connect to the database servers you configure and to serve ads.
• Network state (ACCESS_NETWORK_STATE): used to determine connectivity for your connections.
• Biometric (USE_BIOMETRIC): used only if you enable the optional biometric app lock.
• Advertising ID (AD_ID): used by Google AdMob to serve ads (see Section 2.8).

The App does not request location, camera, microphone, contacts, or full storage permissions, and it does not post notifications.

2.8 Advertising Data (Third-Party)

Unless you purchase the ad-removal option, the App displays advertising through Google AdMob (App Open and native formats). 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

2.9 Information We Do NOT Collect

We explicitly do not collect:

• Personal or contact information
• The servers you connect to, your credentials, your queries, or the data you read or write
• The contents of files you import or export
• 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:

• Connect to the database servers you configure and run your queries and data edits
• Browse databases, tables, and objects and render result grids
• Import and export the files you choose and populate the optional widget
• Remember your query history, snippets, settings, 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 sends your requests to the database servers you specify. Those servers are operated by you or by parties you choose, and their handling of those requests 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

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.
