Help us build the most honest dataset of human emotion ever assembled.
If you'd like to, you can contribute your anonymized check-ins to an open scientific corpus. Researchers studying affective dynamics, bereavement, and emotional flexibility will use it. You will own the donation; you can revoke it at any time.
Why this matters. Most emotion research uses one of two data types: laboratory studies (artificial, small, mostly undergraduates) or scrapes of social media (performative, public, biased toward outrage). Neither captures the texture of an ordinary Tuesday. The literature has been calling for a large, in-the-wild, longitudinal corpus of self-reported emotion for twenty years; we hope Hue. can be that corpus.
What we share. Only what you tell us to. The donation is granular — by hue, by year, with or without timestamps, with or without note text. You see every entry you're sending before you send it. You can take it back at any point.
Who runs the corpus. The Hue. Emotions Corpus is governed by an independent ethics board with members from clinical psychology, bioethics, and computer security. The corpus is hosted on a university research server. Access is granted to credentialed researchers under a signed data-use agreement that prohibits commercial use and re-identification attempts.
Four steps. Your hands at every step.
You choose what to share.
Pick which hues, which date range, whether to include note text. Default is "vividness data only" — no words, just colors.
We strip identifiers locally.
On your phone, before anything is sent. Timestamps are coarsened to month-level. No device IDs, no IP, no phone model.
You preview.
A scrollable view shows exactly what will leave your device. Cancel at any time. We do not pre-load.
You submit.
A signed receipt is stored locally. With it, you can revoke any subset of your donation later. No login required.

This page registers your interest. The actual donation happens inside the app, with a much fuller consent flow. Nothing is donated by submitting this form.

The Hue. Emotions Corpus is overseen by an independent Data Ethics Board drawn from outside the project: a clinical psychologist with expertise in measurement reactivity, a bioethicist who has previously chaired an IRB, and a computer-security researcher specialising in anonymization attacks. The board reviews every researcher access request and every methodological change.
The corpus is published under a data-use agreement that prohibits: (1) commercial use, (2) re-identification attempts, (3) sharing with third parties not bound by the same DUA, and (4) advertising or insurance-underwriting applications. Violations result in revocation of access and, where applicable, referral to the institution's research-misconduct office.
If you'd like to review the full DUA, the corpus governance document, or the ethics board's published opinions before deciding to donate, all three are available on the corpus website (linked from the donation flow inside the app).
