You control everything in your account, including who can see what as well as who has the ability to edit your files. By default you are the only person that will have the ability to edit any of your content on Keep&Share. In order for others to edit your information, you will have to go into the Share Control to give anyone else Edit Rights.
If you want your document or calendar to be ”read-only” (that is, no one will be able to edit it but you) then you will need to make sure that the “Edit Rights” box is not checked next to the names of the people that you have shared your information with in the Share Control.
Alternatively, if you have a paid account you can give others the Direct Access Link for the item that you want to share. The Direct Access Link is a link that you can copy and share with anyone, regardless of whether they have a Keep&Share account or not. This is a unique URL that is automatically generated for each of the files, calendars, photos, etc. in your account and you can find and enable this link in the Share Control.
