Transparency
SigmaCV builds your CV from open research databases and is honest about exactly where every entry comes from, how it decides what's yours, and what it stores about you. The short version: it logs nothing about how you use it by default.
Where your CV data comes from
All of these are open, public sources. SigmaCV reads from them on your behalf — it never writes back to them:
- OpenAlex · ORCID · Crossref — your publications, with citation metadata and field-normalized indicators.
- ORCID · ROR · Wikidata — your verified author identifier, institution names, and public profile links.
- DataCite · OpenAIRE · DBLP — datasets, software and conference papers linked to your identifier.
- Crossref · UKRI · NIH · NSF — funding and grants.
- ClinicalTrials.gov · EU CTIS · WHO ICTRP — clinical trials you are listed on.
- Open Editors Plus · EPO — editorial roles and patents.
How it decides what's yours
Anything matched by a unique identifier — your ORCID or a publication's DOI — is included automatically. Anything matched only by name and organization (some funders and registries have no identifier) is never added silently: it is flagged as a review candidate for you to confirm or reject. Your own name is highlighted by identifier, never by matching the text of a name.
How often it refreshes
Your working CV updates whenever you re-sync. A CV you publish as a living page re-syncs from the sources automatically on a regular schedule, so it stays current without any action from you — and you can trigger a refresh yourself at any time.
What we log
By default, nothing about how you use the app. Optional, consent-gated research logging (for studies on author disambiguation and CV composition) stays switched off until an ethics/IRB protocol is in place, and only records anything after you explicitly opt in. Site analytics are cookieless, first-party and aggregate-only — they never profile individuals.
Your control
You choose what is published, field by field. You can export all your data at any time, and deleting your account removes it. Display choices (what to show, what to hide as “not mine”) are yours and stay local to your CV.
