Querion does not collect, store, or transmit your database credentials or query data to any Querion server. All connection information is stored locally on your device. We collect only anonymous analytics to improve the app.
Querion collects only the minimum data necessary to operate and improve the application. We collect two broad categories of information:
| Category | What | Where stored |
|---|---|---|
| Connection data | Database host, port, database name, username, and password you provide when adding a connection. | Locally on your device only (SQLite). Never uploaded. |
| Usage analytics | Anonymized events (e.g., screens visited, feature usage). No personally identifiable information is attached. | Google Firebase Analytics servers. |
| Purchase data | In-app purchase transactions if you choose to make a donation or purchase. | RevenueCat / Apple App Store / Google Play servers. |
| Crash reports | Device model, OS version, and anonymized stack traces when the app crashes. | Google Firebase Crashlytics servers. |
We do not collect: real names, email addresses, location data, contact lists, or any data retrieved from your databases.
We do not sell, rent, or share any of your data with advertisers or data brokers.
Your database hostnames, usernames, passwords, and any query results never leave your device and are never transmitted to Querion or any third-party server operated by us.
Database connections are saved in a local SQLite database on your device. This data is accessible only to the Querion app and is subject to the same device security protections (PIN, biometrics, encryption) you have configured on your phone.
Querion connects directly from your device to your database server. We do not act as a proxy or intermediary for your database traffic. You are responsible for ensuring your database server is properly secured and that you are authorized to access it.
