Terms of Service
Last updated 2026-10-16
These terms cover the Querium desktop application, this website, and Querium Pro licences. Querium is made by Jheison Novak, an individual developer based in Brazil ("we", "us"). By downloading, installing or buying Querium you agree to them.
Who sells it
Our order process is conducted by our online reseller Paddle.com. Paddle.com is the Merchant of Record for all our orders. Paddle provides all customer service inquiries and handles returns. Payment, taxes, invoices and receipts are handled by Paddle under its buyer terms.
The free version
Querium Free is free for any use, personal or commercial, with no time limit and no account. What is included in it may change between versions; a version you already have keeps working the way it did.
Querium Pro licences
- A licence is a one-time payment. It does not expire and it is not a subscription.
- It includes every update released in the 12 months after the purchase. Versions released in that window keep working with the licence forever.
- One licence is for one person, on up to three machines at a time. Removing it from a machine frees that slot.
- Activating a licence sends its key and an anonymous fingerprint of the machine to our activation service. After that the licence is checked on your machine, offline.
- You may not share, resell or publish a licence key, or work around the licence check.
Refunds
Full refund within 14 days of purchase, no questions asked. A refunded licence stops working. See the refund policy.
Your data and your databases
Querium connects directly from your machine to the databases you configure. Your queries, results and credentials are not sent to us. The optional AI assistant talks to the provider you choose, with your own key, and shows you what it sends before it sends it. Details are in the privacy policy.
You are responsible for what you run against your databases. Querium shows every statement it generates before running it, and you decide whether it runs.
Warranty and liability
Querium is provided "as is", without warranty of any kind. To the extent the law allows, we are not liable for lost data, lost profits or indirect damages arising from its use, and our total liability is limited to the amount you paid for the licence. Nothing here limits rights that the law of your country does not allow to be limited.
Changes
We may update these terms. The date at the top says when they last changed, and a change never takes away what a licence you already bought includes.
