Terms of Service

By using the NumSift website, you agree to these terms. Specific products, APIs, paid services or enterprise engagements may be governed by an order, contract or service description. A specifically accepted agreement controls if it conflicts with these website terms.

NumSift provides information, inquiry channels and processing capabilities related to global phone-number and communication-data screening. Features, coverage, estimates and examples on the website describe the service; actual capabilities depend on the selected product and agreed solution.

You must follow applicable law, platform rules and authorization requirements related to data sources.

• Do not submit, screen or use data obtained without a lawful basis
• Do not use the service for spam, harassment, fraud or unlawful surveillance
• Do not bypass access controls, rate limits or security measures
• Do not disrupt, attack, reverse engineer or access systems without authorization

You are responsible for the lawful source, accuracy, processing basis and downstream use of data you submit. You must obtain required authorization, notice or consent and respond to data-subject requests where applicable.

Rights in the NumSift website, brand, interface, documentation and software belong to their respective owners. These terms do not transfer intellectual property unless expressly stated. You retain rights in content you lawfully submit and grant the limited permission needed to provide the requested service.

We work to maintain the website and services but do not promise uninterrupted or error-free operation. Features may change for maintenance, security, provider changes or product improvements, with reasonable notice when practical.

Unless a specific agreement states otherwise or applicable law requires it, website information is provided as available. Screening output should be reviewed against your business rules and is not legal, compliance or identity advice. Liability and its limits are governed by applicable law and the relevant service agreement.

We may restrict access involving unlawful conduct, abuse or security threats. These terms may be updated, with the revised date shown on this page. Continued website use after an update means you accept the revised terms.
