Pricing FAQ
Is there a free tier?
Yes. 18 of the 35 tools are free in the browser, including the SQL Formatter, JSON and YAML tools, the Parquet Inspector and the Row Group Pruner. No account or card required.
How does the licence work without an account?
You paste your licence key once in Settings → License. It is an Ed25519-signed key verified locally in your browser, so it works fully offline and never calls a server.
What is your refund policy?
30-day money-back guarantee, no questions asked. Request a refund through our payment provider or support.
Can I upgrade from Personal to Team?
Yes. Contact support with your original purchase email and we will help you upgrade — you only pay the difference.
Does it work offline?
Yes. Install DataEngUtils as an app (PWA) and it runs with no network at all after the first load.
