Loses paid hints

This app, Ive noticed, deducts more hints than used, I had 275 hints (bought a special deal), used 2 hints, went to 272. Ive noticed this several times before and needs to be addressed. Plus you lose hints and words previously found when you leave the app. Giving it 3 stars, fix this and its 5
