Terms, privacy & refunds

Last updated 2026-11-15.

License terms

GUI Hub (“the app”) is free to download and use. Its free tools may be used without limit. Pro tools can be tried a few times for free; continued use requires a GUI Hub Pro license.

• A Pro license is a one-time purchase for one person, valid on up to 3 of that person’s computers, for personal or commercial work. It includes the Pro tools available now and those added later, for as long as the app is offered.
• You may not resell, share or publish license keys, or circumvent the license check.
• The source code is published for transparency; it is not open source and is not licensed for redistribution.
• The app runs third-party open-source programs (listed below) which it downloads from their official release pages. Each program is provided by its own authors under its own license. Your use of those programs is governed by their licenses.
• The app is provided “as is”, without warranties of any kind. Always keep backups of important files before renaming, converting or uploading them. To the extent permitted by law, our total liability is limited to the amount you paid for the license.
• We may update these terms; the version on this page applies.

Purchases

Orders are processed by Polar, which acts as the merchant of record and handles payment, invoices and sales tax/VAT. Your receipt and license key come from Polar by email, and you can always see them again in Polar’s customer portal.

Refunds

If GUI Hub Pro doesn’t work for you, you get a full refund within 30 days of purchase — no questions asked. Reply to your receipt email or open a support request. Refunded license keys stop working.

Privacy

• No tracking in the app. The app has no analytics, telemetry or ads, and does not send your files anywhere.
• License checks: when you activate or periodically re-check a license, the app sends the license key and a generic device label (for example “GUI Hub on Windows”) to Polar to confirm it is valid.
• Tool downloads: the first time you use a tool, the app downloads it from GitHub; it also fetches the tool list from this website to learn about new tools. These requests reveal your IP address to GitHub, like visiting any website.
• Network tools: tools whose job is networking use the network as you instruct (for example, Send Big Files passes encrypted data through croc’s relay; Google Photos → Immich uploads to the server you enter).
• Purchases: Polar processes your name, email and payment details under its own privacy policy. We receive your email and order details from Polar to provide support and refunds.
• This website is hosted on GitHub Pages and sets no cookies; GitHub may log visits as described in GitHub’s privacy statement.
• To ask about or delete your data, open a support request or reply to your receipt.
