Set codes are the two-three character combinations that represent sets. For sets released after 2015, the three-character set code can be found in the lower left hand corner.

For older sets, the code may be different depending on your use:

Set symbol images are fetched from the Gatherer. After finding a card with the desired set symbol, right click the set symbol image and open it in a new tab. In the URL you should find the set code, following the 'set='

For watermarks, please reference Keyrune.

Generally, however, the set codes used by Scryfall are accurate.

Cards are saved on your computer under your browser's localstorage, which usually has a limit of 5MB and cannot be changed.

Unfortunately, this means that if you save a lot of cards, you could run out of space.

Your localstorage runs out of space especially fast when you upload images directly from your computer, because the image itself has to be saved. However, if possible, uploading images via URL will save massive amounts of space, allowing you to save many more cards.

And if you do run out of space, don't worry! You can download all saved cards then delete all saved cards, freeing up all 5MB of space. And when you'd like to edit the cards you previously downloaded/deleted, you can reupload them via the file upload (under "Upload previously downloaded cards").
