ArkOwl Features

A few of the ways that ArkOwl stands out from its competitors.

Absolute Data Security

The only way to keep customer data absolutely private is to not keep any in the first place. Other data providers depend on storing and sharing data from customers to protect and power their product. We do not store/share your valuable customer data.


No black box algorithms or mathematical suggestions. No false positives or false negatives. We give you the raw data, tell you exactly what can be inferred from it, and nothing more.

Real-Time Data

Our data is 100% live, real-time data. No pulling from stale, potentially outdated databases.


We take privacy seriously. All data requests are anonymized and requested through ArkOwl so individual data providers cannot track information on our customers.


All connections are secured with 256-bit encryption and no sensitive data are retained in our logs.

Unlimited Users

No limits on users per paid account. Simply pay for the data you use.

Flexible Payment Options

Sign up for a monthly subscription, or pre-purchase queries and pay as you go. We accept credit card, check, or ACH.
