Cygent Privacy Policy

Last updated: April 28, 2026

This Privacy Policy describes how Cyfrin Inc ("Company", "We", "Us", or "Our") collects, uses, discloses, and protects Personal Data when You access or use the Cygent platform (the "Service"). It applies to visitors of Our marketing site, Account holders, members of customer Organizations, and individuals whose Personal Data is incidentally Processed through the Service.

This Privacy Policy should be read together with the Cygent Terms of Service and, for enterprise Customers, the Cygent Data Processing Agreement. Capitalized terms not defined here have the meaning given in those documents.

1. Who We Are

The data controller responsible for Personal Data Processed under this Privacy Policy is:

Cyfrin Inc 9066 Cascada Way Naples, FL 34114 United States Email: support@cyfrin.io

Where We Process Personal Data on behalf of an Organization (e.g., Smart Contract Code submitted for analysis, Findings, integration content), the Organization is the Controller (or Business) and We act as Processor (or Service Provider). Our processing in that capacity is governed by the Data Processing Agreement.

2. Scope

This Privacy Policy applies to Personal Data We Process as a Controller, including:

• Account registration and authentication data;
• Billing and contact data for Customer administrators;
• Service operational and usage metrics used for Our own administrative purposes;
• Marketing-site visitor data (cookies, analytics signals, contact-form submissions).

It does not govern Personal Data We Process on behalf of an Organization as a Processor — that processing is governed by the Agreement and DPA.

3. Personal Data We Collect

3.1 Data You Provide

• Account Data — email and password sign-up: email address, name (optional), and password. We store passwords as one-way hashes using a memory-hard algorithm (scrypt); We never store, log, or have access to Your password in plaintext. We also store an email-verification status and any verification tokens We issue.
• Account Data — OAuth sign-up: where You sign in with GitHub or Google, We receive Your name, email address, avatar, and provider user ID from the OAuth provider. We do not receive or store Your authentication credentials for those providers.
• Two-factor authentication data: TOTP secret (encrypted at rest), recovery codes (hashed). Two-factor authentication is mandatory for all Accounts; existing Accounts may be subject to a short grace period before enforcement.
• Organization Data: Organization name, role, membership, Instance configuration, billing contacts.
• Communications: messages You send Us through email, support requests, or contact forms.

3.2 Data Generated Through Your Use of the Service

• Smart Contract Code and Findings: Repository code You submit for analysis, audit Findings, code context, severity classifications, and remediation recommendations. (Processed on Your Organization's behalf — see Section 2.)
• Integration Data: access tokens and configuration for connected Third-Party Integrations (GitHub, Slack, Discord, Telegram), encrypted at rest using AES-256-GCM.
• Usage and Operational Data: job execution history, audit statistics, command invocations, timestamps, IP addresses, user-agent strings, error and diagnostic logs.

3.3 Data Collected Automatically

• Cookies and similar technologies: session cookies for authentication, and limited first-party analytics. See Section 8.
• Device and connection data: IP address, browser type, operating system, referring URL, pages visited, and approximate location derived from IP.

3.4 Data from Third Parties

• OAuth provider data: profile information GitHub or Google returns when You sign in.
• Third-Party Integration data: repository, pull request, channel, and message metadata returned by GitHub, Slack, Discord, or Telegram when You connect those services.
• Payment processor data: billing status from Our payment processor (We do not receive or store full payment card numbers).

3.5 Special Categories

The Service is not intended to Process special categories of Personal Data (GDPR Art. 9) or data relating to criminal convictions (GDPR Art. 10). Please do not submit such data through the Service.

4. How We Use Personal Data

We Process Personal Data for the following purposes:

We do not use, and do not permit Our Sub-processors to use, Customer Personal Data (including Smart Contract Code, Findings, prompts, completions, or embeddings) to train, fine-tune, or otherwise improve any generally available machine learning or AI models. See Section 5.3 of the DPA for the technical and contractual measures We rely on.

5. AI Processing and Automated Decision-Making

The Service uses large language models to analyze Smart Contract Code and generate Findings. As described in the Terms of Service:

• AI-generated Findings are not a substitute for a professional security audit.
• Findings may include false positives and false negatives.
• The Service does not make legal, financial, or employment decisions about individuals.

We do not engage in automated decision-making producing legal or similarly significant effects on individuals within the meaning of GDPR Art. 22.

6. How We Share Personal Data

We share Personal Data only as described below. We do not sell Personal Data, and We do not "share" Personal Data for cross-context behavioral advertising as those terms are defined under the CCPA/CPRA.

6.1 Sub-processors

We engage Sub-processors to provide infrastructure, inference, and operational services. As of the Last Updated date, Our Sub-processors include:

A current list of Sub-processors is maintained at https://app.cygent.dev/legal/subprocessors. We require each Sub-processor to be bound by data protection obligations no less protective than this Privacy Policy and the DPA.

6.2 Third-Party Integrations You Connect

If You connect a Third-Party Integration, Personal Data flows between the Service and that platform according to Your configuration. Your use of those platforms is governed by the third party's own terms and privacy policy.

6.3 Legal and Safety Disclosures

We may disclose Personal Data when We reasonably believe disclosure is necessary to:

• Comply with applicable law, legal process, or governmental request;
• Enforce the Terms of Service or investigate potential violations;
• Detect, prevent, or address fraud, security, or technical issues;
• Protect against harm to the rights, property, or safety of the Company, Our users, or the public.

6.4 Business Transfers

If We are involved in a merger, acquisition, financing, or sale of assets, Personal Data may be transferred as part of that transaction. We will notify You and require any successor to honor the commitments in this Privacy Policy.

6.5 With Your Consent or at Your Direction

We share Personal Data with other parties when You direct Us to do so or otherwise consent.

7. International Data Transfers

The Service is operated from data centers in the United States. Customer Personal Data stored by the Service — including Instance data, platform and agent databases, logs, and observability data — is hosted in the United States.

Onward transfers occur:

• to LLM inference Sub-processors identified in Section 6.1, for the purpose of analyzing Smart Contract Code; and
• to Third-Party Integrations that You choose to connect.

Where transfers leave the EEA, UK, or Switzerland to a country not recognized as providing an adequate level of protection (including the United States, except where the recipient is certified under the EU–US Data Privacy Framework), We rely on the European Commission's Standard Contractual Clauses (and, where applicable, the UK International Data Transfer Addendum and Swiss FDPIC amendments) together with supplementary technical and organizational measures. For enterprise Customers, the SCCs are incorporated by reference into the DPA.

A copy of the relevant transfer mechanism is available on request from support@cyfrin.io.

8. Cookies and Similar Technologies

We use a small number of first-party cookies to:

• Keep You signed in (session cookies);
• Remember preferences (e.g., theme);
• Measure aggregate usage so We can debug and improve the Service.

We do not use third-party advertising cookies or cross-site tracking. You can control cookies through Your browser settings; disabling session cookies will prevent You from signing in.

9. Data Retention

We retain Personal Data for as long as necessary to provide the Service and for the purposes described in Section 4. Specific retention periods include:

• Account Data: for the life of the Account, plus a reasonable period after termination for legal, audit, and dispute-resolution purposes.
• Smart Contract Code and Findings: until You delete them through Service controls or until termination of the Agreement, after which they are deleted within ninety (90) days unless You request earlier deletion or return.
• Operational logs: retained for a limited period sufficient for debugging, security, and capacity planning.
• Backups: residual copies in routine backups are deleted in accordance with Our backup rotation schedule.

We may retain Personal Data longer where required by law or to establish, exercise, or defend legal claims.

10. Security

We implement technical and organizational measures designed to protect Personal Data against accidental or unlawful destruction, loss, alteration, unauthorized disclosure, or access. These include:

• TLS 1.2+ for all external connections;
• AES-256-GCM application-layer encryption of integration tokens at rest;
• Storage-level encryption provided by Our hosting providers;
• Email/password and OAuth (GitHub, Google) authentication, with mandatory two-factor authentication for all Accounts;
• One-way password hashing (scrypt) with per-credential salts; password complexity requirements; screening of new and reset passwords against known-breached password databases via k-anonymous lookup; rate limiting on sign-in, sign-up, password-reset, and two-factor endpoints;
• Role-based access control within Organizations;
• Per-Organization Instance isolation;
• Least-privilege access to production systems for Cyfrin personnel;
• Secrets managed through 1Password and Varlock in production, kept out of source control;
• Logging, monitoring, and alerting on defined security signals;
• Background screening (where permitted by law), confidentiality obligations, and security training for personnel.

A more detailed description of Our technical and organizational measures is set out in Section 6 of the DPA. No system is perfectly secure; if You believe Your Account has been compromised, contact Us at security@cyfrin.io.

11. Your Rights

Subject to applicable law, You have the following rights with respect to Personal Data We hold about You:

• Access — obtain a copy of Personal Data We hold about You;
• Rectification — correct inaccurate or incomplete Personal Data;
• Erasure — request deletion of Personal Data, subject to legal retention obligations;

For requests that cannot be completed through the Service, contact Us at support@cyfrin.io. We will respond within the time required by applicable law (generally 30 days under GDPR; 45 days under CCPA/CPRA, extendable as permitted).

12. Children's Privacy

The Service is not directed to individuals under 18 years of age, and We do not knowingly collect Personal Data from anyone under 18. If You believe a child has provided Us with Personal Data, contact support@cyfrin.io and We will take appropriate steps to delete it.

13. Third-Party Sites and Services

The Service may contain links to third-party websites and services. We are not responsible for the privacy practices of those sites and encourage You to review their privacy policies before providing Personal Data to them.

14. Changes to This Privacy Policy

We may update this Privacy Policy from time to time. When We make material changes, We will update the "Last updated" date at the top and, where required by law, provide additional notice (e.g., by email or through the Service). Your continued use of the Service after the effective date of an updated Privacy Policy constitutes acceptance of the changes.
