Documentation
Getting Started with LookUp
Everything you need to know about launching, using, and closing the app.
Starting the App
After installing LookUp, simply double-click the app icon to launch it. You'll be prompted to enter your Secret Key on first launch. Once activated, the app is ready to use.
Runs in Background
LookUp runs silently in the background — it does not appear on your taskbar. It waits for you to press Alt+M to look up a word, then disappears when you click away.
Quitting the App
Since LookUp doesn't appear on the taskbar, you quit it by pressing Alt+M to open the popup, then clicking the ✕ close button in the top-right corner of the popup.

Privacy & Terms
Your data stays yours. Always.
Our Privacy Commitment
LookUp operates locally and securely. It does not track your activity, collect personal information, or access any private data. The app only processes the word you request a definition for.
The requested word is sent to an open dictionary API solely to retrieve its definition. No data is ever stored, sold, or associated with your identity.
No Tracking
We collect zero analytics or behavioral data.
No Data Collection
Your activity is never stored or read passively.
Terms of Use
1. One-Time Activation. LookUp requires a one-time Secret Key activation (₹50 / $7.99) to unlock full functionality. The key is tied to your device and never expires.
2. No Refund Policy. All purchases of Secret Keys are final and non-refundable. As this is a digital product with instant delivery, refunds are not supported once a key has been generated.
3. Third-Party APIs. Definitions are sourced from open dictionary APIs (FreeDictionary API, Wiktionary). Accuracy is subject to those services.
4. No Redistribution. You may not redistribute, sell, or repackage LookUp without explicit written permission from the author.
