Transparency

How BurnoutZero turns personal wellbeing signals into team insight without ever exposing an individual — explained plainly.

Last updated 6/17/2026.

What is collected

Your daily check-ins (energy, mood, sleep), activities you log, and — only if you connect a calendar — meeting-load patterns. That is it. No message content, no keystrokes, no location.

How aggregation works

Your data contributes to a team aggregate (for example, an average burnout score) only if you have consented. The number a manager sees is computed across many people; your individual contribution is never visible inside it.

What k-anonymity means here

k-anonymity means a figure is only ever shown when it blends at least k consenting people together (the team’s configured minimum). If too few people have consented, the manager sees nothing at all — never a near-individual number. We also withhold comparisons that could let someone subtract one cohort from another to single you out.

Where your data lives

In the EU (Hetzner, Finland/Germany), encrypted in transit. Our sub-processors and their purposes are listed on the Trust Center. Cross-organization benchmarks, where enabled, use only anonymized hashes and require a large, multi-organization cohort before any comparison is shown.
