Yes! We store learner progress for each learner so that they can continue with where they left off.
However, for collections using the learners' access method everyone can access, a random ID is generated for each learner. If the learner clears their browser cookies or decides to access using another device, their progress will be lost.
Other learners' access methods require email addresses and progress data is stored according to their email address. Hence, learners are able to proceed with where they left off as long as they use the same email address.
