Under no circumstance are complete messages retained or transferred to me (invalidCards) or third parties in any way by the public instance of this bot. All messages are immediately processed by the bot purely to provide its functionality.
Parts of the message that include the linking syntax of the bot (text in [[square brackets]], {{curly brackets}} or --double dashes--) is processed and sent to the API of the relevant wiki depending on the requested functionality, but is never logged in any way by WikiOperatingBuddy.
