Product Privacy Notice
We provide authentication, fraud-prevention, and device-intelligence services (the “Services”) that operate on behalf of our business customers (“Customer Controllers”).

We do not use personal data for purposes other than to carry out our data processor obligations, and do not otherwise sell or share personal data.
De-identified Data
SLC may process aggregated or anonymized data (“Deidentified Data”) to evaluate, improve and develop our products and services.
Subprocessors
We engage vetted subprocessors to support operational, hosting, analytics, and technical needs. A current list of our subprocessors is available {{here}}.
International Transfers
SLC is headquartered in the United States. We may transfer personal data to the United States or to other jurisdictions outside an individual’s country of residence. We employ strong protective measures along with standard contractual clauses (SCC) for the personal data that is transferred from the EU or UK.
Security Controls
SLC employs a range of technical and organizational measures to protect the Customer Data entrusted to us. Our information security program is designed to protect against the unauthorized access, loss, misuse or alteration of such data, including encryption in transit and at rest; continuous monitoring and logging; secure software development lifecycle and ongoing penetration testing and vulnerability scanning.
While we take these and many other precautions to protect Customer Data, no technology, software or security protocol can be guaranteed to be 100% secure.
Data Subject Rights Support
We assist our Customer Controllers with any requests to carry out individual privacy rights, including the right to access, delete, correct, port, and restrict data. Because we act only on our controllers’ instructions, we cannot respond directly to rights requests for data that we process as a data processor. Once the controller with whom you do business instructs us, we will support them and carry out the required actions under the EU GDPR, UK GDPR and other applicable privacy regulations.
Updates
SLC reserves the right to change or update this Privacy Notice at any time by posting a notice of such updates on our site. We encourage you to visit our privacy page from time to time and to read the Privacy Notice to learn of our current privacy practices and protections.
