XLS Padlock.
Buy once, ship forever.

One-time charge. You receive a perpetual license plus 12 months of free upgrades and basic support. After the first year, you can optionally renew at a discounted rate. Renewal is optional, you keep every version you obtained during your maintenance period forever.

Your activation code always works with the version of XLS Padlock you purchased. On top of that, 12 months of maintenance gives you free major and minor upgrades, access to the latest versions, registered downloads (WooCommerce Kit, Subscription Kit, key generators, PHP SDK), and priority basic technical support by email and forum.

Your license never expires, you keep using the versions you already have. Future versions may require an updated activation that is only issued while maintenance is active. Renewing while your maintenance is still active gives a 30 percent discount on the next maintenance year. Once it has lapsed, upgrades cost 85 percent of the new license price.

One license allows activation on two computers as long as the registered user is the only one using it. A deactivation facility lets you move the license freely between machines. If a computer is damaged or lost, contact us for a manual deactivation.

Go to your G.D.G. Software account, sign in with the email you purchased with, and open My Products. Your activation code is listed there. If you do not have an account yet, create one with the purchase email to retrieve your license.

Checkout is processed by our resellers Paddle and FastSpring. They handle local taxes, VAT, currency conversion, and reseller services. After the order is placed, you receive your license details by email within minutes. For wire transfer, SEPA, purchase orders, money orders, or check, use FastSpring or contact us.

The free Trial edition is full-featured: test everything before you buy. After purchase, refunds are limited to genuine technical incompatibilities within 30 days of the order (at our discretion, minus payment processing fees). Once your activation code is emailed and used, the license is yours. Please use the Trial first, that is what it is for.

If we ever shut down, we commit to publishing an offline activation key that works on any PC, so our customers are never blocked.

Yes. Paddle and FastSpring (our resellers) issue a tax-compliant receipt at checkout with your company name, VAT number, and the local tax rules applied. Add your VAT number during checkout to make the receipt B2B-ready. Past invoices are available from the reseller account or by request.

Each developer compiling workbooks needs an XLS Padlock license. The compiled EXE you ship is royalty-free, so end-user distribution is unlimited. For teams, volume discounts apply starting at the second license. Contact us with your team size to receive a quote.

None of your workbook content, ever. XLS Padlock itself checks its own activation against our license server (the activation request only carries your license code and a machine fingerprint). The activation flow your end users run is HTTPS to your own server, not ours. Compiled workbooks do not phone home unless you configure them to.

Install XLS Padlock once. Run it with the trial first. After purchase, enter the activation code received by email into the same installation. The workbooks you already compiled remain valid, no need to rebuild. Maintenance period starts the day of the purchase.
