We're releasing TinyPoll, which can be added to any Slack org for free. It includes anonymous polling, summaries, poll editing, and comes with security and privacy as a primary concern - we remove all polling data after 7 days and just keep what we need for analytics (no PII is ever stored).
You can install this and start using it now and we'd love your feedback.
