A Slack survey app where anonymous really means anonymous
Pulse checks, eNPS and retro questions asked in Slack, with answers stored against an irreversible hash instead of a name. Nobody can see who said what, including you.
How is your workload this sprint?
12 responses · names never stored, aggregates only
Three things that make anonymity more than a label
Most tools mean 'we hide the name in the interface'. People work that out quickly, and then they answer like people who have worked it out.
Names are never stored
An anonymous response is written against an irreversible per-run hash. There is no column holding the name, so there is nothing to look up later, subpoena, or leak.
Nothing shows under 5 answers
Results stay hidden until at least 5 people have responded. A three-person run cannot be un-anonymized by counting who is missing.
Not even the owner sees names
This is not a permission you can grant yourself in settings. The dashboard shows aggregates, and the export follows the same rule.
An anonymous survey is only worth running if people believe it
The value of the answers is exactly equal to how safe people feel giving them. One story about a manager who worked out who wrote something is enough to make every future survey in that company return nothing but "about right".
That is why the threshold and the missing name column exist rather than a promise in the privacy policy. You can tell your team how it works, and the answer does not depend on trusting anybody's good intentions, including ours.
What we store, and for how long, is written out in the privacy policy. Choosing between a survey and a quick vote? See all four ways to create a poll in Slack.

Anonymous Slack survey FAQ
- How do anonymous surveys work in Slack?
- Create a check-in and pick the Survey, eNPS or Weekly Pulse preset. asyncmate DMs the questions on your schedule, exactly like a standup, but answers are collected without a name attached and results appear in a protected Survey results view in the dashboard instead of a channel digest.
- Is it actually anonymous, or just hidden from other members?
- Actually anonymous. Responses are stored against an irreversible per-run hash rather than a member, so no screen, export or database query can attribute one to a person. On top of that, aggregates are withheld until at least 5 people respond, which is the case where a small group could otherwise be worked out by elimination. One honest limit: the text of a free-text answer can still give its author away to people who know the context, so skip self-identifying details in what you write.
- Can the workspace owner see who said what?
- No. That is the difference between an anonymous survey and a survey with names hidden in the UI. There is no admin toggle that reveals them, because the identifying data was never written down.
- What can I use this for?
- Team pulse checks, eNPS, retro input, workload and burnout checks, and post-incident questions where the honest answer and the diplomatic answer are different. Anywhere a name attached to the answer would change the answer.
- How often should we run one?
- Weekly or fortnightly is enough for a pulse check; eNPS is usually quarterly. Asking too often is how a survey turns into noise people click through without reading, which produces data that looks fine and means nothing.
- Which plan are anonymous surveys on?
- Pro, like the other anonymity features: anonymous polls and hidden-until-close poll results are Pro too. Regular polls, with visible votes, stay free on every plan.
Ask the question people won't answer in a channel
Pick the Survey, eNPS or Weekly Pulse preset, choose who gets it and how often. Anonymous surveys are part of Pro; polls stay free on every plan.
