Sinter installs a lightweight monitoring client on authorized offender devices, allowing agencies to capture digital activity across iOS, Android, Windows, macOS, and Chromebook environments. The platform records searches, browser activity, messaging attempts, file-sharing actions, and app-level behaviors tied to supervision conditions. All data is encrypted, securely transmitted, and displayed in an officer dashboard that provides real-time visibility across an entire caseload. This ensures consistent, lawful monitoring regardless of device type or operating system.
Sinter uses a continuously updated keyword, phrase, and emoji library tailored to high-risk categories including CSAM, pornography, sexual exploitation, victim contact attempts, grooming behavior, extremist or violent propaganda, and predatory intent. Machine learning models analyze context to distinguish between accidental exposure and deliberate engagement. When risk patterns appear—such as repeated searches, escalating curiosity, or coded emoji use—Sinter generates an immediate alert and automatically creates an entry in the event log for officer review.
Sinter scans URLs, search queries, file names, messaging text, and web traffic for indicators associated with prohibited or harmful content. The system cross-references activity against known CSAM-hosting domains, pornography networks, and extremist propaganda sources. If a device user attempts to access, view, download, or share this content, Sinter blocks the request (where policy allows) and issues a real-time violation alert. Contextual analysis helps distinguish accidental exposure from deliberate behavior, improving accuracy for officers.
Sinter’s machine learning models evaluate the context around keywords, page content, and user behavior patterns to filter out irrelevant noise. Instead of flagging every match, the system weighs intent, repetition, surrounding text, timestamps, and historical patterns. Over time, the model adapts to the individual’s behavior and the agency’s supervision rules, reducing false positives and surfacing only meaningful risks. This saves officers hours of manual review and minimizes alert fatigue across large caseloads.
Every flagged event—whether a high-risk keyword, a blocked URL attempt, or a violation—is automatically compiled into a structured, timestamped report. These reports include device identifiers, screenshots (where allowed), metadata, policy references, and a clear narrative summary. Because they are generated directly from digital logs and cannot be altered after creation, the reports provide a defensible chain of evidence that meets courtroom expectations for accuracy and integrity. Agencies use them during hearings, breach reports, revocation processes, and case reviews.
Sinter only monitors devices that are explicitly approved and authorized under a supervision order, and only captures activity tied to the conditions of release. The platform does not operate as general surveillance. It operates within the legal frameworks set by courts, supervision agencies, and statutory requirements. All monitoring settings are configurable by the agency, ensuring conditions such as CSAM prohibition, victim non-contact, or pornography bans are enforced consistently while respecting privacy boundaries defined by policy and law.
Sinter delivers real-time alerts through its officer dashboard, SMS, or email (depending on agency preference). Alerts include attempts to access prohibited websites, search for illegal content, contact victims, use banned apps, or engage in behaviors associated with grooming or predatory conduct. Each alert links directly to the supporting evidence and violation metadata. Immediate notification allows officers to intervene quickly, prevent escalation, and document the breach for court or case management systems.
Sinter is designed to match real-world justice workflows rather than replace them. Officers assign devices, configure monitoring rules, and receive alerts in a format that mirrors current supervision processes. Automated reporting replaces hours of manual documentation. Dashboards allow managers to view caseload-wide risk trends, team performance, and violation history. Agencies can integrate Sinter’s outputs into existing case management systems via export or API, ensuring minimal disruption to established procedures.
Sinter can detect a wide range of digital behavior tied to supervision conditions, including searches for CSAM, pornography, or violent content; attempts to contact victims; interactions with dating, messaging, or anonymity apps; access to extremist content; and actions consistent with predatory or grooming behavior. The system also logs repeated attempts, escalating searches, and cross-platform patterns of concern. All activity is automatically documented, categorized, and added to a defensible audit trail.
Sinter is not a surveillance tool and not a case management platform. It is a purpose-built public safety technology category called Offender Digital Monitoring. Unlike generic monitoring software, Sinter is engineered specifically to enforce court-ordered digital conditions, detect high-risk behavior, and provide legally defensible evidence. It integrates into probation and parole workflows, uses machine learning to reduce noise, and focuses on measurable outcomes: deterrence, faster detection, and reduced officer workload. This makes it the first monitoring solution designed for public safety rather than enterprise IT or corporate oversight.
