US Cop is an independent, offline directory of a deliberately limited set of current nationwide federal law-enforcement contacts. This edition includes source-attributed contacts for the FBI, DEA, ATF, U.S. Marshals Service, and U.S. Postal Inspection Service. Each record shows its official source and verification date. Search works offline, and important values can be copied. Phone, Maps, Mail, and Safari open only after you choose and confirm an available action. The directory is intentionally conservative. It is not a complete directory of federal, state, local, tribal, or territorial agencies. Contact details can change after verification; confirm important information directly with the agency. US Cop is independent and unofficial. It is not affiliated with or endorsed by any government or law-enforcement agency. It is not for emergencies. In the United States, call 911. Privacy: no account or cross-app tracking. Version 4.2.1 sends first-party analytics events for installation, Apple Search Ads attribution, access checks (including diagnostic information about whether the App Store purchase record could be confirmed), and verified subscription purchases. They include device identifiers; device, app, and locale metadata; and purchase details such as transaction IDs, product, dates, and the App Store receipt. Our analytics server also stores the IP address and an approximate location based on it. See the privacy policy for details. Analytics problems never change your access to the directory. US Cop is free to download. Full access to the directory needs a US Cop Weekly subscription. If you bought US Cop before it became free, you keep full access without subscribing. US Cop Weekly: $4.99 per week in the U.S. (other storefronts show the local price). Payment is charged to your Apple Account when you confirm the purchase. The subscription renews automatically every week until you cancel. Cancel anytime in Settings > your name > Subscriptions at least 24 hours before the renewal date to avoid the next charge. No free trial. Terms of Use: https://beforeafter.appholdings.org/terms/us-cop-ios.html Privacy Policy: https://beforeafter.appholdings.org/privacy/us-cop-ios.html
