If you contact us, we collect certain personally identifiable information, such as email and name, so that we can respond to enquiries.

When providing a file for conversion, we do not read or collect the file’s contents for reasons different from converting the file. We collect the number and types of errors when converting, as well as the original file size and name, for statistical purposes.

Your files are automatically and irreversibly deleted from our servers at the latest after 72 hours, for conversion with an error. The files of successful conversions are deleted 24 hours after their completion. You can also manually initiate the deletion by clicking the DELETE NOW button.

Your uploaded files will not be given out or sold to anyone. The same applies for the data associated with your MConverter account, if you have one. Any other personally identifiable information will not be given out or sold, either.
