We show our work.

Lemma is built on the premise that trust requires transparency. The SCI formula is public. The roadmap is open. The data model is documented. Nothing is hidden.

Open SCI formula

The SCI is not a black box. Every component is published and auditable.

Practice

Sessions completed, XP earned

Proof

Evidence events, assessments, proofs

Reliability

Show rate, consistency, ratings

Freshness

Recency of evidence events

Integrity

Governance flag (binary penalty)

SCI = Practice (0–25) + Proof (0–40) + Reliability (0–20) + Freshness (0–15), minus any Integrity penalty. The formula is versioned and deterministic – the same evidence always produces the same score.

Data transparency

What we store, who can see it, and how to export it.

Data type	Who can see it	Exportable
Profile data	You, employers you share with	Yes
Session evidence	You, your session partner	Yes
SCI score & breakdown	You, and anyone you share your passport with	Yes
Wallet ledger	You only	Yes
Authentication tokens	Never exposed – stored hashed	N/A
Analytics events	Aggregate only, no individual tracking	N/A

To request a full data export or account deletion, contact privacy@getlemma.io.

Open verification API

Every verification endpoint is public. Anyone can verify a Lemma passport without a paid account or API key. We will never gate the ability to check someone's credentials – that defeats the purpose.

Pricing transparency

LemmaCoins are not tied to dollar amounts by corporate decision-making. The LC economy is governed by explicit, versioned rules published in our docs. No dark patterns, no hidden fees, no credit expiry surprises without notice.

Give your skills somewhere to live.

Bring your evidence together and start building a Skills Passport that can grow with you.
