Are my raw files stored in Speclib? No. Your raw files are read through a translator and the spectra and associated metadata are uploaded to your Dashboard. The original (or raw) files are discarded.

Can I keep my data private? Yes. You maintain full control of your data, and you can choose to keep your data ‘Private’ or publish and make it ‘Public’ anytime from your Dashboard, but we hope you will share your data and hard work with the world!

Can I revert my Public data and make it Private again? Yes. Maybe you need to update or noticed an error in your data or metadata after making it Public (it happens!). Simply go to your Dashboard, select the checkbox of the file(s) to edit under ‘Public Data’, and select ‘Make Private’ or click Unpublish Selected button at the bottom of the list. These data will now appear in your Private Data holding and ready for further editing.
