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
One post per person per day
A built-in daily limit keeps the channel from turning into a firehose. It runs on the same hashed tokens, so no posting history builds up.
Read the technical details: the design, the exact data we store, and where the limits are.
How it works
Dead simple.
-
01
Someone shares a thought
Anyone on the team types /sincere The pizza we get on Fridays sucks! Only they can see it.
-
02
A random delay breaks the trail
The message posts anywhere from seconds to 24 hours later, so timing never points at a person.
-
03
The team votes anonymously
Everyone can agree or disagree, once per message, without anyone knowing who voted.
-
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 and 1-on-1s carry power dynamics, so the quiet majority stays quiet.
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
What starts as an annoying process quietly grows into the reason people leave.
Sincere gives them a safe voice
People can raise the real issue without betting their reputation on how it lands, and leadership hears it in time to act.
Free for teams under 50 people.
No credit card required. Once it's installed, anyone on the team can post with /sincere right away.
