How this tranche was selected

Explicit High-impact catalog records are selected first. Ties are ordered by category priority, lower tracked-field completeness, and current route evidence. This is an evidence-work priority, not a live search-volume, ranking, removal-success, or competitor-share estimate.

The catalog snapshot contains 1,043 customer-ready records. The first tranche is exactly 20% of that catalog and includes 209 explicitly High-impact records. This is an evidence-work priority, not a live search-volume, ranking, competitor-share, broker-quality, or removal-outcome estimate.

Why this tranche is prioritized for evidence work

1. Upstream and public-record aggregators

Some large data providers compile information from public records, commercial sources, or other providers. Their exact inputs, downstream relationships, and current record-matching practices vary, so this tranche treats source, ownership, route, and evidence fields as items to verify rather than assuming that one request changes every downstream copy.

2. Public people-search surfaces

People-search portals can expose contact or public-record information through searchable listings. Visibility, matching accuracy, fields, source records, and removal routes differ by provider and can change over time; a profile or search result is not proof that every displayed field is accurate.

3. B2B sales and professional-intelligence vendors

Some B2B vendors publish or license professional contact and organization data. The exact data types, lawful basis, audience, and suppression route depend on the provider and record; exposure risks can include unwanted outreach, impersonation, or phishing, but no particular outcome should be assumed.

4. Identity and advertising-data matching

Some advertising and identity services may match identifiers across contexts or devices. Whether a provider performs a particular match, what identifiers it uses, and whether an individual can be linked across environments requires provider-specific evidence; this index does not assume a universal cross-device profile.

5. Mobile telemetry and location services

Some mobile-data services receive app, device, advertising-identifier, IP, or location signals through SDKs, customer integrations, or other sources. Precision, consent, retention, and downstream use vary; the location-data page and individual provider records identify selected evidence rather than claiming that every service collects the same signals.

6. Rights and provider-specific requests

Privacy rights and request routes vary by jurisdiction, provider role, data source, verification, and legal exception. A request may affect one provider or processing purpose, but it does not automatically remove public records, downstream copies, search results, or unrelated data held elsewhere.

Evidence boundary

A source-backed profile may combine provider-published material, official registry context, structured catalog fields, and bounded read-only observations. DNS, URL reachability, route observations, or a privacy email do not prove official ownership, mailbox acceptance, request delivery, deletion, monitoring, or non-republication. Review the provider route and use the profile as a research reference.

First-tranche FAQ

What does the first 20% data broker tranche mean?

It is a maintenance and publication priority containing 209 of 1043 customer-ready catalog profiles. The order reflects documented impact, evidence gaps, category relevance, and route state; it is not a ranking of broker quality, market share, removal success, or search volume.

Are these data broker profiles verified?

Each profile exposes the source-backed fields currently recorded for the catalog snapshot, including source dates, workflow details, route observations, and named gaps. A reachable URL or recorded contact does not prove mailbox acceptance, request delivery, deletion, monitoring, or non-republication.

Why are some first-tranche profiles still missing evidence?

The first tranche is designed to focus research where it can improve the most important shared surfaces. Missing fields remain visible so the queue can be reviewed and refreshed from provider-published, regulator, registry, or bounded observation evidence instead of being filled with guesses.

Does OfflistMe automatically remove data from these brokers?

No. OfflistMe prepares browser-local drafts and routes. You review the details, send or submit the request yourself, save confirmation, verify the listing, and follow up when needed. Provider workflows and outcomes vary.
