QueryPad Support

Email: support@querypad.eonix.lk — we reply within 2 business days.

When you write, include your QueryPad version (Settings → Version), your device and OS version, and — if the problem is a connection error — the exact error message. You can attach a redacted diagnostics file from Settings → Export diagnostics; it never contains hosts, user names, SQL, results or passwords.

Frequently asked questions

Which databases does QueryPad support?

PostgreSQL, CockroachDB, MySQL, MariaDB, SQL Server, SQLite files, ClickHouse, Cassandra, MongoDB and Redis. Every networked connection requires TLS. The server versions QueryPad is tested against are PostgreSQL 16, MySQL 8.4, MariaDB 11.4, SQL Server 2022, MongoDB 7.0, Redis 7.4, CockroachDB 24.1, ClickHouse 24.8 and Cassandra 5.0; nearby versions generally work. Oracle is not supported.

How do I connect to SQL Server?

Select SQL Server, enter the server host and TCP port (1433 by default), database, and SQL login. Windows integrated authentication, Entra ID and named-instance discovery are not supported; enter the instance's TCP port. Use a trusted certificate with Verify full, or import a CA certificate with Verify CA. Separate T-SQL batches with standalone GO lines; semicolons stay inside the batch so local variables work.

Why won't my server connect without TLS?

QueryPad always encrypts networked connections. Enable TLS on the server, or connect through an SSH tunnel (Pro) and use TLS mode require if the server has a self-signed certificate. Prefer verify-ca with your server's CA certificate so the connection is also verified.

What do the TLS modes mean?

• Verify full (default): the certificate must be trusted by your device and match the host name.
• Verify CA: the certificate must be signed by the CA file you import; the host name is not checked.
• Require: traffic is encrypted but the server is not verified. QueryPad shows a warning while you use it.

Which SSH keys can I use?

Ed25519 and ECDSA (P-256, P-384, P-521) keys in OpenSSH or PKCS#8 format, with or without a passphrase. RSA keys are not supported yet — create an Ed25519 key with ssh-keygen -t ed25519 and add its public key to the server.

QueryPad says the SSH host key changed.

QueryPad blocks the connection because the server's identity no longer matches the key you trusted, which can indicate an attack. Confirm the new fingerprint with your server administrator, then open the tunnel settings and choose Forget host key before connecting again.

Why do connections close when I switch apps on iPhone or iPad?

iOS suspends apps in the background, so QueryPad closes connections cleanly and keeps your last results on screen. Tap Reconnect (or return to the app — the active connection reconnects automatically).

How do I open a SQLite file from iCloud Drive?

Choose New Connection → SQLite file and pick the file. QueryPad remembers it and reopens it after a restart. A file that cannot be edited where it lives, such as one in some file providers, is opened as a working copy; changes to that copy are not written back to the original.

What does Free include, and what does Pro add?

Free: two connections, schema browser, editor with autocomplete, results up to 1,000 rows, and history. Pro: unlimited connections, SSH tunnels, unlimited rows with paging, saved queries and folders, iCloud sync, CSV/JSON export, charts, table data editing, the relationship view, and the "Run Saved Query" shortcut.

How do I restore my purchase on another device?

Open the paywall or Settings and tap Restore Purchases while signed in with the same Apple Account.

How do I cancel my subscription?

Settings → QueryPad Pro → Manage, or your Apple Account's Subscriptions page.

How do I delete my data?

Settings → Erase all data… removes everything QueryPad stored, including synced records in your iCloud account when sync is on.
