Yes, they do. In order to support data integrity and traceability, very few elements within SciNote can be deleted - most of them can only be archived.
Most of the elements in SciNote can only be achieved, so if you archive a task that contains files, it will still take up storage space.
The size of a file uploaded is limited to 50 MB on the free account and 300 MB on the SciNote Premium account. Your total storage space is determined by your current plan.
If you have any additional questions, please, do not hesitate to contact us at support@scinote.net. For more information about the Premium plans, please request a quote.
