Check this thread on Apple developer forums, there is a link to translation of French export forms: https://devforums.apple.com/thread/109830

According to the FAQ on iTunes Connect you need French export forms only if the app contains:

  - any encryption algorithm that is yet to be standardized by
  international standard bodies such as IEEE, IETF, ISO, ITU,
  ETSI, 3GPP, TIA, etc. or not otherwise published; or 

  - standard (e.g., AES, DES, 3DES, RSA) encryption algorithm(s)
  instead of or in addition to accessing or using the encryption
  in Apple OS
