Stop measuring what people will say in public

Start measuring what people actually think. Our privacy preserving surveys give you the patterns, never the people: individual responses are stored as fragments, unreadable by you, by us, by anyone. No exceptions. No back doors. That privacy is why people answer freely

security

Nothing to steal

We don't build a respondent database. Email addresses aren't stored anywhere, and no table exists that links an answer to a person. A break-in can't steal that link, because it doesn't exist.

privacy

Not from the inside either

Answers are distributed across three machines and exist nowhere as a whole, not even for the organiser. You can't see who answered what either, and that's one thing less to carry.

Beyond safe answers

Traditional surveys assume a promise of anonymity is enough. Research shows otherwise: once anonymity is provable rather than promised, the answers change. You hear what you need to know...

We make cryptography accessible to any organisation. Hard maths, easy to use.

How it works

Scan the QR code, done

You get a unique code: one code, one participant. It proves you were invited without revealing who you are. After that you're in the pool, and new surveys reach you without scanning again.

No account, no signup

Scanning gives you a key that lives only on your device. That's what gets you back to your own answers — no name, no address, no password. You can secure that access later, so you keep it when you switch devices.

Your answers stay yours

The organiser sees totals and summaries. Individual answers can be visible, but never as your completed survey and never alongside your other answers. That profile doesn't exist anywhere, not for S3ntiment either.

Set up a survey in minutes

Choose your questions, decide who can take part, and start. After that you're out of it — the answering happens without you.

Build your pool

Generate a batch of single-use codes and hand them out as a printed QR, by mail, or over chat. You know who you invited, but not who redeemed. Once someone joins the pool, you can reach them again without issuing a new code.

Results without profiles

You get totals, percentages and summaries. Individual answers can be readable, but never as one completed survey. That profile doesn't exist anywhere, and not for S3ntiment either.

for who?

At work

Employees who doubt their answer is really anonymous say nothing. Not about unsafe situations, not about what's actually going on. Here nobody can trace an answer back — not HR, not us.

Public bodies

What do residents think of the plan for their street? Not what they say at the consultation evening, but what they think at home. A running barometer gives councils that picture throughout the project, not only on the evenings where the loudest voice wins.

Events

Feedback three days later, by an email nobody opens, gets you the opinion of whoever still cares enough to click. A code on the badge or on the table gets you the opinion of whoever was there — and anyone who changes their mind mid-event can change their answer.

Be your own YouGov

Building a panel usually means building it for someone else: it sits with the vendor, and whoever leaves starts over. Here the panel belongs to the group that builds it — with colleagues, with other organisations, as a DAO. Together you decide who can put out a survey and who sees the results

The most valuable feedback is in the answers people don't dare give. We didn't solve that with a promise. We solved it by never making the connection.
