Terms of Service

Last updated: October 12, 2026. We may update these terms from time to time; continued use after an update constitutes acceptance of the revised terms.

By subscribing to LitDigest, you agree to the following terms.

1. Service

LitDigest delivers curated academic paper digests to your email based on your research interests. We aggregate publicly available preprint and working-paper metadata from sources including arXiv, bioRxiv, medRxiv, ChemRxiv, EarthArXiv, EcoEvoRxiv, engrXiv, ESS Open Archive, EGUsphere, Preprints.org, PsyArXiv, SocArXiv, Law Archive, NBER, and SSRN, and published-journal metadata when available under your plan. We rank papers by relevance and deliver a summary at your chosen frequency. Your data is handled per our Privacy Policy.

Complimentary Pro access

When this offer is available, eligible new signups receive complimentary Pro access upon first verifying their email. This access lasts until January 31, 2027 at 4:00 p.m. Pacific Standard Time (February 1, 2027 at 00:00 UTC), or 30 days after first verification, whichever is later. New signups after that date receive 30 days of complimentary Pro from first verification. No payment card is required, and this offer does not automatically create a paid subscription or charge you. Any future paid plan requires a separate checkout and your agreement to its payment terms.

Unless another valid Pro entitlement applies, your account returns to Free when complimentary access expires: one preprint digest, delivered at most weekly. Extra digest profiles and Pro settings remain saved while your account remains active, but Pro-only features are unavailable without Pro access. We may send service notices about your access and its expiration. Other temporary or permanent Pro grants retain their own access terms.

5. Source Content and Intellectual Property
