Frequently asked questions
Purchase, license, privacy, product, and refund questions — answered.
Purchase & license
How do I activate my license?
Open DataEngUtils → Settings (⌘,) → License → paste the key from your purchase email → Activate.
Can I use my license offline?
Yes. After the first activation, your license works fully offline with a 7-day grace window between online checks.
What is your refund policy?
30-day refund policy via our payment provider (Dodo Payments) or support. Refunded licenses are revoked automatically.
What is the difference between Personal and Team?
Personal includes 1 seat (1 Mac activation). Team includes 5 seats for squads. Both include all 20+ tools and one year of free updates.
License
I lost my license key. How do I get it back?
Use the Resend License page and enter the email you used at checkout. You can request a resend up to 3 times per hour.
Can I use my license on multiple Macs?
Personal licenses allow 1 activation. Team licenses allow 5 activations. Deactivate from Settings → License before moving to a new machine.
Privacy & security
Does DataEngUtils send my data anywhere?
No. Tools run locally on your Mac. The only network call is a weekly license ping that sends a license hash and machine ID — never your file contents or clipboard data.
Is my Parquet or CSV data uploaded during conversion?
Never. File tools process data entirely on your machine using Polars in Rust. Nothing is uploaded to the cloud.
Product
Does DataEngUtils support Apple Silicon?
Yes. We ship a universal binary optimized for Apple Silicon and Intel Macs.
How is this different from DevUtils?
DevUtils targets general developers. DataEngUtils focuses on data engineering — Parquet, CSV, dbt, warehouses, and pipelines. The apps are complementary, not identical.
Will there be a Windows version?
macOS is our launch platform. A Windows version is on the roadmap (M13).
Refunds
How do I request a refund?
Email support within 30 days of purchase with your order email. Refunds are processed through Dodo Payments and your license key is revoked automatically.
What happens to my license after a refund?
Your license is revoked immediately. The desktop app will detect revocation on its next weekly online check (or sooner if you verify manually).
