Thank you very much for your interest in Saaspose API.
I would like to share that all of your files are stored in your own storage at Saaspose. We do not look into your files. However, some times, if there is some issue with your particular document, we'll have to have a look into that particular document only for investigation purposes, and that will be only if you share the file and allow us to have a look into that. That is used by our support/development team for testing and we do not share such files with anyone and we do not use these files for any purpose other than testing. And this is only in case we need to test some particular issue. Otherwise, your files remain secure in your own space and no one accesses those files.
You can also post your files to Saaspose storage using HTTPS, so that they're transferred to us securely. In addition to that, you can also keep your files on external storage like Google Drive, DropBox, Amazon S3 etc. and Saaspose API will process the files from there. Moreover, even if you upload the files to Saaspose storage, you can delete them using either by API call or by Web UI after they're processed. Also, some of the API resources even allow you to submit your files and process them with Saaspose API without saving them on the server.
We're looking forward to work with you.
Support Developer, Saaspose
