Sentinel Brief
Effective 7 July 2026
Sentinel Brief (“the terminal”, “we”) is a monitoring and research tool that aggregates openly available information — news wires, open-source intelligence feeds, public flight and maritime transponder data, seismic and hazard feeds, satellite ephemerides, and prediction-market data — into one interface, with automated scoring and AI-generated summaries.
The terminal is a research aid. Nothing in it — including AI-generated briefings, market analyses, probabilities, or “edge” figures — is financial, investment, legal, or safety advice. Signals are aggregated from third-party sources that we do not control and cannot guarantee; confidence grades describe our scoring process, not certainty. Always verify against primary sources before acting on anything, and never rely on the terminal for personal-safety decisions.
Membership is billed through Stripe at $30 per month or $150 per year. New members receive a 72-hour free trial; a payment card is required to start it, and the paid plan begins automatically when the trial ends unless you cancel first. You can cancel at any time from the billing portal — cancellation stops future charges and access continues to the end of the paid period. Except where required by law, payments already made are non-refundable; if something went wrong, write to us and we will be reasonable.
Don’t abuse the service: no scraping or reselling the feeds, no attempting to circumvent access controls or rate limits, no use of the terminal to plan or facilitate harm to any person, vessel, or aircraft, and no use that violates applicable sanctions or export laws. We may suspend accounts that breach these rules.
Data reaches the terminal from third parties (including, among others, public ADS-B and AIS networks, USGS, NASA, NOAA, CISA, CelesTrak, gpsjam.org, GDELT, Polymarket, and news publishers). Their availability, accuracy, and licences are theirs; feeds may lag, drop, or be withdrawn. Trademarks belong to their owners; no affiliation or endorsement is implied.
Briefings and market analyses are generated by large language models over the signals we collect. They can be wrong, incomplete, or out of date, and are clearly part of the research-aid character of the service described in section 2.
The terminal is provided “as is” without warranties of any kind. To the maximum extent permitted by law, our total liability for any claim arising out of the service is limited to the amount you paid us in the twelve months before the claim.
We may update the service and these terms; material changes will be posted here with a new effective date. Continued use after a change is acceptance of it.
