# CaseStatusTracker > Independent tools for understanding user-provided USCIS case JSON. Not affiliated with USCIS or the U.S. government. Free analysis parses JSON in the visitor browser, orders supplied events, and flags missing or ambiguous timestamps. Unknown event codes remain unverified. We do not provide approval probabilities, approval dates, internal USCIS access, or legal advice. Optional saved cases and paid reports require sign-in and explicit consent. One-time report checkout does not create a subscription. Annual report access is $29.99 per year, renewing until canceled, with the subscription confirmed through Stripe checkout, and includes up to 20 new report versions per day. Users import their own data. Automatic monitoring, email alerts, peer benchmarks and case Q&A are not included. No monthly or lifetime purchase is offered. CaseStatusTracker is the publishing organization. Public content shows author attribution and source links. Official references are sources, not endorsements or affiliations. Private case data, dashboards, API responses, credentials and payment callbacks are not public reference material. ## Public tools - [Home](https://casestatustracker.net/): Product explanation, direct answers, and official source attribution. - [USCIS JSON Reader](https://casestatustracker.net/tools/uscis-json-reader): Accepted JSON shape, limits, and browser-local analysis. - [Case Timeline](https://casestatustracker.net/tools/case-timeline): Ordering of supplied events and missing-date warnings. - [Silent Update Checker](https://casestatustracker.net/tools/silent-update-checker): Comparison of supplied record and event timestamps, with interpretation limits. ## Optional - [About](https://casestatustracker.net/about): Publisher identity and independence statement. - [Contact](https://casestatustracker.net/contact): General support and corrections; do not submit case JSON or credentials. - [Official USCIS Case Status Online](https://egov.uscis.gov/): External official case-status tool. - [USCIS](https://www.uscis.gov/): External agency information and official instructions.
