This app is no longer being maintained and I have not played Hearthstone in some time. At least they raised the amount of decks you can have from 18 to 30.

Hearthstone Wiki has some info on deck importing which includes how to copy a deck from within Hearthstone. Make sure to paste the full text of what was copied and not just the code for the deck into Hearthstone Deck Saver.
If you want to test it out without copying a deck from the game, you can use these sample decks.
Q: Why create this app?
A: In Hearthstone, you can only save 18 decks, but you might want to quickly save some decks that you don't use too often, such as decks that help you fulfill a quest like playing a certain number of dragons, or cards with battlecries, etc.
Q: Why can I only access my saved decks with the browser that saved them?
The app saves the data for your decks to local storage which means it is saved to a storage area in a particular browser and never gets transmitted over the internet to a server. Also, since it's saved to your browser, take care to not delete local storage.
Q: Can I export or backup my deck data?
A: Not yet! Let me know if you're interested in that.
