Electronic device and translation support method

An electronic device comprising:

• a controller configured to acquire data indicating first text in a first language;
• storage configured to store a secret character string indicating secret information;
• and
• a communication device configured to perform communication with a translation server which translates the first text into second text in a second language that is different from the first language, wherein
• the controller determines whether or not the secret character string is included in the first text,
• upon determining that the secret character string is included in the first text, the controller converts the secret character string into a mask character string,
• the mask character string is a character string for hiding the secret character string,
• the controller transmits data indicating the first text in which the secret character string has been converted into the mask character string to the translation server through the communication device,
• when the communication device receives data indicating the second text, the controller searches the second text for the mask character string translated into the second language, and
• the controller converts the mask character string in the second language into the secret character string in the second language.
