FlashLingo

What does it do?

• Requires the user to login using Google authentication
  • If the user has logged in during the last 6 hours, uses cookies to authenticate the user
  • Does not store any data about the user except the user's Google id (salted and hashed using SHA-256)
• Allows the user to:
  • Create flash cards for Swedish (eftersom svenska är fantastik) words and phrases (input by the user)
    • Translation is done using the Google Translation API
  • Review and answer the cards
    • Cards are picked randomly with probabilities depending on the correct / incorrect answer ratio
    • On a correct answer, a "Correct!" message pops up
    • On an incorrect answer, the card flips and displays the correct answer
• Stores the cards in a SQLite database
• Works in all resolutions
