Do not run files directly from inside the compressed ZIP archive. First, extract it:

• Windows: Right-click the downloaded ZIP file → select Extract All… → choose a destination (Desktop or Documents) → click Extract.
• macOS: Double-click the ZIP file. macOS extracts it automatically into the same folder.

We recommend naming the extracted folder after the app you downloaded (e.g. DOCX Optimizer) so it is easy to find later.

Open the extracted folder. Inside, locate the file named index.html — it will display your default browser icon (Edge, Chrome, Safari, or Firefox). Double-click index.html to launch the app. It opens directly in your browser and runs entirely on your local machine — no installation required and no internet connection needed after activation.

Nothing to enter, nothing to unlock — your 30-day free trial starts automatically the moment you open the app. There's no upfront license key, sign-in, or compliance notice blocking you from working.

Already subscribed? Click Enter license key in the app's top bar at any time to activate your Premium subscription — it takes effect immediately.

The trial gives you full Premium access for 30 calendar days — no credit card, no sign-up required to start. Here's the full process:

1. Download the app from the Download Portal — every download is open, no key or registration needed.
2. Open it. Your 30-day trial begins the moment you launch the app for the first time.
3. Use the full Premium version for 30 days — every feature, no nags, no limits.
4. On day 30, the trial ends. No charge is ever made unless you choose to subscribe. See pricing →

You can optionally leave your email on the Free Trial page for a reminder before your trial ends — this is not required to use the trial itself.

See our Terms of Use and EULA for full details.

When the 30-day trial expires, full access ends. Specifically:

• No data loss. Every file, document, and project you created during the trial is fully preserved and accessible.
• No charge. The trial itself never requires a card or payment method — nothing is billed unless you actively subscribe.
• No action required. The trial ends cleanly — no reinstall, no cancellation needed.

To continue with full access, subscribe monthly — cancel anytime. See pricing →

Your license key is delivered automatically by email as soon as your first payment is confirmed — typically within a few minutes:

1. Subscriptions start from inside the app itself (Enter license key → Subscribe in the top bar), which takes you to a secure Stripe checkout page. You'll see a confirmation screen immediately after your first payment.
2. An email is sent containing your license key — a long signed code, not a short PIN — for you to paste into the app's activation box.
3. If the email doesn't arrive within 10 minutes, check your spam or junk folder.
4. Still nothing? Contact us with your order ID and we'll help you get it resent.

Your key is tied to your subscription. Keep the email — it's your proof of subscription.

When you enter your key inside the app and click activate:

• The app computes a device fingerprint in your browser — based on things like your screen, timezone, and browser configuration, not your physical hardware serial numbers. This happens entirely on your device.
• Your license key is a cryptographically signed record tied to that fingerprint. It's built to work on this specific browser/device going forward.
• All Premium features unlock immediately — no restart required.
• Once activated, the app keeps working fully offline — no internet connection is needed to use any feature. When you do have a connection, it briefly re-confirms your subscription status in the background, so a canceled subscription or a locally-forged clock can't be used to fake continued access.

This is a one-machine license. Activating the same key on a different browser or device produces a different fingerprint, so it won't validate there. See EULA §3 for the full device-binding policy.

Visit the Download Portal — every available app is downloadable immediately, no key required. Downloading gets you the same file whether you're trying it free or already subscribed; you activate Premium afterward from inside the app itself using the key from your subscription confirmation email. You'll always get the latest version this way, and future updates are included at no extra charge while your subscription is active.

Check the original confirmation email from your payment processor first — your key and order ID are both in that email. If you can't find it, contact us with your subscription email address and order ID. We'll verify your subscription and resend your key within 24 hours, Monday to Friday. We cannot resend keys without order verification.

Yes — cancel anytime, no questions asked. Contact us with your order ID and we'll cancel your subscription for you. A few things to know:

• Cancelling stops future billing — you won't be charged again.
• Access continues until the end of your current billing period. There are no prorated or partial-period refunds.
• Your documents and files are never affected by cancellation — everything you created stays on your machine.
• You can resubscribe at any time from the Pricing page.

No. Each license is bound to one device at the point of activation, based on a browser fingerprint generated on your machine. A single key won't validate on a second device or browser. Each machine requires its own separately subscribed license at the standard price. There are no multi-seat discounts. See EULA §3 and §5 for the full policy.

Updates are available through the Download Portal at any time — no key needed to download. After replacing the file with the new version, re-enter your license key if Premium features aren't already unlocked. Updates are included at no extra charge for as long as your subscription stays active.

Yes — contact us with your order ID and a brief description of the situation (device replaced, browser reset, etc.) and we'll help you get re-activated on your new device. This is handled case by case rather than through an automated self-service tool, so response times can vary.

First, confirm your operating system meets the requirements listed on each app's detail page. On macOS, navigate to System Settings → Privacy & Security and allow the app if prompted. On Windows, click "More info → Run anyway" on the SmartScreen dialog. If the issue persists, contact us with your OS version and app version number.

No — you can use every feature fully offline once the app is open. All document processing happens entirely on your local machine: there's no cloud processing and your documents never leave your device. The one exception is licensing: activating a key, and periodically re-confirming trial/subscription status when you do have a connection, involves a small network call carrying only a device ID and a timestamp — never your files or their content. See Terms of Use for the full disclosure.
