📖 Download & activation

1. After you buy

Right after checkout you'll get an email from our store (Lemon Squeezy) containing your download link, your license key (looks like XXXXXXXX-XXXX-XXXX-XXXX-XXXXXXXXXXXX) and your receipt. The success page shows the same download button and key.

2. Install

1. Download the MyNotebook zip and extract the whole folder somewhere you like (e.g. Documents\MyNotebook).
2. Double-click MyNotebook.exe. Windows may show "Windows protected your PC" the first time — click More info → Run anyway.

3. Activate

1. Open the book and click the 🔑 License button at the bottom of the left page.
2. Paste your license key and click Activate. (This one step needs internet.)
3. Done — the app now works fully offline on this PC.

Moving to a new computer

In the app: 🔑 License → Deactivate this PC. Then activate on the new PC with the same key. If your old PC broke and you can't deactivate, just contact support with your order email — we'll free the license for you.

Your notes are always yours

Notes live in the data folder next to MyNotebook.exe. Back that folder up any time, or use Export (⬆ in the app) to save your whole book as one file. A license problem never blocks reading or exporting your notes.
