Trust

Anonymity you can check.

Every anonymous feedback tool says trust us. We publish how ours works instead, down to the hashing scheme, so you can see for yourself.

01

No identities stored

Votes and rate limits use hashed tokens instead of user IDs. Your name is never stored next to your words.

02

Timing can't out you

Messages post at a random time within 24 hours. We never store when you submitted.

03

Votes stay sealed

We only keep the totals. Who voted, and which way, is never recorded.

04

AI content moderation

Automated filters block harassment, profanity, and threats while preserving honest feedback.

You don't have to take our word for any of this. Read the technical details: the design, the exact data we store, and where the limits are.

How it works

Dead simple.

  1. 01

    Someone shares a thought

    Anyone on the team types /sincere The pizza we get on Fridays sucks! Only they can see it.

  2. 02

    A random delay breaks the trail

    The message posts anywhere from seconds to 24 hours later, so timing never points at a person.

  3. 03

    The team votes anonymously

    Everyone can agree or disagree, once per message, without anyone knowing who voted.

  4. 04

    Leadership learns early

    Morale issues, process problems, and culture gaps surface while they're still fixable.

Why it matters

Silent problems are expensive problems.

Most employees won't speak up

Retros feel performative. 1-on-1s have power dynamics. Your quiet majority stays silent.

By the time someone quits, it's too late

Exit interviews reveal problems that existed for months. The damage is already done.

Small issues compound fast

A frustrating process becomes culture debt. A bad meeting pattern becomes attrition.

Sincere gives them a safe voice

No fear of retaliation. No awkward confrontations. Just honest signal when it matters.
