Transparency and accountability
About CallSlayer Intelligence
CallSlayer Intelligence is a free public-interest research service for understanding unwanted calls and texts. It combines clearly labeled government complaint aggregates, privacy-thresholded CallSlayer observations, available number intelligence, and reviewed evidence into cautious, source-visible answers.
Mission
Make unwanted-call intelligence useful and accountable
Our mission is to help curtail—and ultimately end—spam calls, robocalls, and unwanted texts by making caller intelligence, evidence-preservation guidance, public reporting options, and accountability tools freely available.
CallSlayer Intelligence is not a court, regulator, carrier, credit bureau, or legal adviser. A complaint, score, carrier label, or website clue is a signal to investigate—not proof that a person or business placed a call or violated the law.
Methodology
How numbers, reports, and conclusions are produced
- Normalize published US phone-number fields into a consistent number key.
- Keep FTC, FCC originating-number, and FCC advertiser-number counts separate because their fields and reporting windows differ.
- Publish CallSlayer network observations only after the applicable privacy threshold is met; never publish an individual user’s case or evidence.
- Label carrier, line-type, caller-name, provider-registry, website, and reputation information by source and limitation.
- Use the strongest supported facts for conclusions while explicitly preserving spoofing, reassignment, porting, and incomplete-data caveats.
- Continuously score public number pages for evidentiary depth and distinctiveness; only the curated launch cohort is submitted for search publication.
Dated research reports use immutable aggregate snapshots and show their source dates. Live trend pages can change as public data and privacy-safe aggregates are refreshed.
Sources
Where the public intelligence comes from
- Federal Trade Commission Do Not Call data for published complaint aggregates.
- Federal Communications Commission unwanted-call complaint data for originating- and advertiser-number mentions.
- FCC Robocall Mitigation Database for provider filings. A provider match describes network context, not caller identity.
- Privacy-thresholded aggregate CallSlayer observations. No identifiable account, call, case, recording, recipient speech, or contact is published. A caller-only excerpt may appear only after explicit administrator review and redaction.
- Available phone-number enrichment and reviewed website clues. These can be incomplete, stale, or incorrect and are labeled accordingly.
Each number result includes an evidence ledger when source-specific evidence is available. Research reports show dataset dates, methodology, and interpretation limits.
Privacy
What is—and is not—published or measured
Public Intelligence pages contain government aggregates, reviewed public facts, privacy-thresholded number-level totals, sanitized number enrichment, and explicitly approved caller-only excerpts. They do not publish a CallSlayer user’s identity, account key, recipient number or speech, case, raw call, recording, unreviewed transcript, screenshot, evidence file, or contact information. Approved excerpts can be retracted independently.
Acquisition analytics use a random anonymous journey identifier and sanitized page, source, and campaign fields. CallSlayer Intelligence does not store IP addresses, full referring URLs, browser fingerprints, transcripts, messages, or screenshots in acquisition analytics.
Messages and screenshots submitted to the forensic analyzer are processed for the requested analysis and are not added to the shared public intelligence database. See the CallSlayer Privacy Policy for the broader service policy.
