## Data

- Keep data: reasonable TTLs
- Use data: You must not, and must not permit any third party to: Use the Service for any unlawful, fraudulent, harmful, or deceptive purpose, or in violation of any applicable law or third-party right. Resell, sublicense, lease, or redistribute the API output (“Output”) as a standalone product or data feed. Use the Output to build, train, improve, or operate any API, dataset, model, product, or service that competes with Lavrox. Systematically scrape, harvest, or accumulate Output to compile or enrich an independent database, threat-intelligence feed, or location-lookup tool. Reverse engineer, decompile, or attempt to derive source code, or copy the features or design of the Service. Probe, scan, or test the vulnerability of the network, breach or circumvent authentication, rate limits, or billing controls, or access the Service through undocumented interfaces. Interfere with or disrupt the Service, or transmit malware or malicious code. Share API keys across unrelated parties, or create multiple accounts to evade Plan limits or free-tier allowances. You must not use the Service or Output: As the sole or primary basis for any decision that produces a legal or similarly significant effect on an individual (including eligibility for credit, insurance, employment, housing, or government benefits), or for any purpose regulated by the US Fair Credit Reporting Act or analogous legislation. For unlawful surveillance, or to identify, track, or profile an individual in breach of applicable privacy law. In sanctioned regions, or by sanctioned or restricted parties [...] In addition to the Acceptable Use Policy, you must not: Use IPWho output to compile, derive, or enrich a standalone IP-intelligence database, threat feed, or location-lookup product, Systematically enumerate IP space (e.g. sequentially polling ranges such as 1.1.1.0/24 or looping exhaustive IPv4/IPv6 blocks) beyond legitimate, real-time analysis of your application’s own traffic. [...] Even where a Plan is described as “unlimited,” use remains subject to fair use, determined reasonably by Lavrox.
