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 Cassandra/Scylla mobile application (the "App").
The App is an Android client for Apache Cassandra and ScyllaDB clusters that you specify. It connects directly from your device to the clusters you configure using the native CQL binary protocol. 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.
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 cluster, you provide its details — host and port, authentication credentials, and transport options such as TLS with optional CA pinning and mutual TLS (mTLS) client certificates. This configuration is stored locally on your device and is not collected by us.
When you open a connection, the App communicates directly from your device to the Cassandra or ScyllaDB cluster you specified using the native CQL binary protocol — there is no server-side agent and no REST gateway. Your CQL statements, schema queries, and their results travel between your device and that cluster — not through us. We do not see, receive, or store your clusters, credentials, queries, or data. You are responsible for ensuring you are authorized to access any cluster you connect to.
The App stores the following data only on your device:
| Data | Collected | Stored | Shared | Purpose |
|---|---|---|---|---|
| Connection profiles | Yes | Device only | No | Hosts, ports, and TLS options for clusters you configure |
| Credentials | Yes | Device only (encrypted) | No | Passwords encrypted at rest with the Android Keystore (AES-GCM), and mTLS client certificates |
| Query history | Yes | Device only | No | Your recent CQL statements |
| App settings | Yes | Device only | No | Theme, language, and other preferences |
| Purchase state | Yes | Device only | No | Cached "remove ads" entitlement (reconciled with Google Play) |
This data is stored exclusively on your device. We do not have access to it, and it is never transmitted to our servers.
INTERNET): required to connect to the clusters you configure and to serve ads.ACCESS_NETWORK_STATE): used to detect network availability.AD_ID): used by Google AdMob to serve ads (see Section 2.5).The App does not request location, contacts, camera, microphone, storage, or other sensitive runtime permissions.
Unless you purchase the ad-removal option, the App displays advertising through Google AdMob (app-open, banner, and native formats). Our advertising partner may collect:
Where required, the App uses Google's User Messaging Platform (UMP) to obtain your consent for personalized advertising. Ad requests never fire before consent allows them. This data collection is governed by Google's Privacy Policy: https://policies.google.com/privacy
We explicitly do not collect:
Data stored on your device is used locally to:
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.
We do not sell, trade, or rent your personal information to third parties.
The App integrates the following third-party services, which handle data according to their own privacy policies:
| Service | Purpose | Privacy Policy |
|---|---|---|
| Google AdMob | Advertising | https://policies.google.com/privacy |
| Google User Messaging Platform (UMP) | Ad consent management | https://policies.google.com/privacy |
| Google Play Billing | Process the one-time ad-removal purchase | https://policies.google.com/privacy |
Separately, the App communicates directly with the Cassandra and ScyllaDB clusters you specify. Those clusters are operated by you or by parties you choose, and their handling of your connections and data is outside our control.
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.
Data stored on your device remains until you delete it within the App, clear app data in device settings, or uninstall the App.
Data collected by Google's advertising, consent, and billing services is retained according to their respective policies.

We may update this Privacy Policy from time to time. We will notify you of any changes by updating the "Last Updated" date and, for material changes, displaying a notice within the App.
We are not responsible for the data collection, use, or security practices of third-party services integrated into the App, including Google AdMob, Google UMP, and Google Play Billing, nor for the clusters you choose to connect to.
We are not responsible for any loss of data stored locally on your device, including your connection profiles and query history.
TO THE MAXIMUM EXTENT PERMITTED BY APPLICABLE LAW, WE SHALL NOT BE LIABLE FOR ANY INDIRECT, INCIDENTAL, SPECIAL, CONSEQUENTIAL, OR PUNITIVE DAMAGES RESULTING FROM YOUR USE OF THE APP.
