+The main purppose of this repository is have a backup of the <a href="https://github.com/MALSync/MALSync">MAL-Sync</a> MAL to Streaming page mapping database. But using the data for other uses is allowed. For commercial use <a href="mailto:lolamtisch@gmail.com">contact us</a>.
 The data is updated once a week. Wrong/missing mappings are not seldom, specially mangas, but because they are generated through all the users of MAL-Sync it should correct itself over time.
