Their data retention policy is deliberately vague. Submitted a DSAR and the response took 42 days and was incomplete. Retention far exceeds what they claim publicly.
The amount of biometric data collected during a simple verification is staggering. Most users have no idea what they are consenting to.

KYC (Know Your Customer) platforms typically collect a wide range of personal data. This includes high-resolution photographs of government-issued IDs such as passports, driver licenses, and national identity cards. Many platforms also capture a live selfie or short video for facial matching, extracting facial geometry data including the distance between eyes, nose shape, and jawline contours. Some read NFC chips embedded in modern passports to extract the biometric data stored there. Beyond documents, platforms often log device fingerprints, IP addresses, geolocation, and behavioral biometrics like typing speed and mouse movements. This data is used not only for the immediate verification but can also feed machine learning models that improve future fraud detection. The breadth of collection means that a single verification event can generate a surprisingly detailed digital profile of you.
Retention periods vary significantly across the industry and are often longer than users expect. Some providers claim to delete biometric data within 30 to 90 days of a successful verification, but many retain it for years or indefinitely, particularly when the data is used to train and improve their AI models. Under GDPR, companies must have a lawful basis for each retention period and must disclose it in their privacy policy. In practice, audit and compliance obligations in regulated industries like banking can justify retention for five to seven years. Some providers hash or tokenize biometric templates but keep the derived data permanently. The safest approach is to submit a Data Subject Access Request (DSAR) to the specific company to find out exactly what they hold, how long they plan to keep it, and under what legal basis they justify the retention.
Whether a KYC provider can sell your data depends on the jurisdiction and the terms you agreed to. Under GDPR, companies generally cannot sell biometric data without explicit consent, and even with consent the sale must serve a specific, disclosed purpose. Under CCPA, California residents can opt out of the sale of personal information. However, many verification providers share data with their corporate clients, subprocessors, cloud infrastructure providers, and sometimes law enforcement agencies when legally compelled. Some providers also aggregate anonymized or pseudonymized data for analytics products. The distinction between selling and sharing is often blurred in privacy policies. Read the data processing agreements carefully, and look for clauses about affiliates and partners. If the provider operates globally, your data may be shared across subsidiaries in jurisdictions with weaker protections.
Many identity verification platforms claim GDPR compliance, but the reality is nuanced. GDPR compliance requires a lawful basis for processing, which for biometric data falls under Article 9 and demands explicit consent or a substantial public interest justification. Platforms must conduct Data Protection Impact Assessments (DPIAs), appoint Data Protection Officers when required, and implement data minimization principles. They must also provide clear privacy notices and honor data subject rights within strict timelines. In practice, several major KYC providers have faced scrutiny from European data protection authorities for overcollection, unclear retention policies, and insufficient transparency. The processing of special category data like facial biometrics triggers the highest level of GDPR obligations. A platform being certified or claiming compliance does not guarantee it; enforcement actions and audits reveal frequent gaps between policy and practice.
To submit a DSAR, start by identifying the data controller, which is usually the company that asked you to verify your identity, not necessarily the third-party verification platform they used. Send a written request via email to the address listed in their privacy policy, typically a privacy@ or dpo@ address. State clearly that you are making a request under GDPR Article 15 (or CCPA Section 1798.100 if in California). Include enough information to identify yourself, such as the email used during verification and an approximate date. You do not need to explain why you want the data. The company must respond within 30 days under GDPR or 45 days under CCPA. Request all personal data held, the purposes of processing, retention periods, and any third parties the data was shared with. If they fail to respond, file a complaint with your national data protection authority.
After verification, your data follows several possible paths depending on the provider and their client agreements. The verification result, typically a pass or fail status, is returned to the requesting company. The biometric data itself may be retained by the verification provider for audit trails, dispute resolution, regulatory compliance, or model training. Some providers convert your facial image into a mathematical template and delete the original photo, while others keep everything. Your government ID images may be stored separately from biometric data with different retention schedules. In the worst cases, data is backed up across multiple data centers and cloud regions, making true deletion difficult even when requested. Some providers share aggregated fraud signals derived from your verification with industry consortiums. The lack of standardized post-verification data handling is one of the biggest privacy gaps in the identity verification industry.
Cross-border data transfers introduce significant privacy risks. When you verify your identity with a platform headquartered in one country but processing data in another, your biometric information may travel through jurisdictions with different legal protections. After the Schrems II ruling invalidated the EU-US Privacy Shield, transfers from the EU to the US require Standard Contractual Clauses (SCCs) or other safeguards, but enforcement is inconsistent. Data routed through countries without adequacy decisions from the EU Commission may lack meaningful protections. Some KYC providers use cloud infrastructure with servers in multiple regions, meaning your data could be replicated to countries you would not expect. Intelligence-sharing agreements like Five Eyes can also expose your data to foreign government access. Always check where a provider processes and stores data, and whether they offer data residency options that keep your information within your jurisdiction.
Document verification involves checking the authenticity of a government-issued ID by analyzing security features like holograms, microprint, fonts, and document structure. It may include reading MRZ (Machine Readable Zone) codes and NFC chips. This process confirms the document is genuine but does not necessarily confirm the person presenting it is the document holder. Biometric verification adds a layer by comparing the person presenting the document to the photo on it, typically through a live selfie or video. It extracts facial geometry and runs a matching algorithm to determine if the face matches the ID photo. Some systems also include liveness detection to prevent spoofing with printed photos or deepfakes. Biometric verification is more invasive from a privacy standpoint because it creates and processes special category data under GDPR. Document-only verification collects less sensitive data but provides weaker identity assurance.
Several emerging technologies offer identity verification with reduced privacy impact. Zero-knowledge proofs allow you to prove attributes like age or nationality without revealing the underlying document data. Self-sovereign identity frameworks such as those built on Hyperledger Aries or the W3C Verifiable Credentials standard let you carry reusable credentials in a digital wallet, reducing the need for repeated document uploads. Some platforms offer on-device verification where biometric processing happens locally on your phone and only a pass-fail result is transmitted. The EU Digital Identity Wallet initiative aims to provide government-backed credentials that can be selectively disclosed. Decentralized identifiers (DIDs) allow identity assertions without a central database. While these alternatives are maturing, adoption remains limited. For now, the most privacy-conscious approach is to ask what data is collected, demand deletion after verification, and prefer services that offer on-device processing.
If a KYC provider is breached, act quickly because biometric data cannot be changed like a password. First, confirm the breach by checking the company statement and monitoring resources like HaveIBeenPwned. Document everything: when you were notified, what data was exposed, and any communications from the provider. Submit a DSAR to understand the full scope of your exposed data. If government ID images were compromised, contact the issuing authority about the risk of identity fraud and consider placing fraud alerts on your credit files. File a complaint with the relevant data protection authority, as breaches of biometric data carry severe penalties under GDPR. Consider joining any class action lawsuits, as several major KYC breaches have resulted in significant settlements. Enable monitoring services if offered by the breached company. Long term, push for regulation requiring biometric data to be processed on-device rather than stored centrally where it becomes a high-value target.
