No. Pep does not ping you during or after your work day.
When we do decide to bring in elements like prompting to share a fact or reminders to take feedback or play a quiz, it will be an opt-in/out feature that you can choose to go for or pause as required.
That said, there are alerts for badges earned and peer feedback responses that are based on the activity of your peers that Pep will keep you updated on. If you have any problems regarding pings by Pep please write to email@example.com and we will look into it immediately.
