Privacy Policy

Introduction

KLEAN13 ("we," "us," or "our") is an email list hygiene and validation service operated by Send13, LLC. This Privacy Policy explains how we collect, use, disclose, and safeguard information when you visit v2.klean13.com, use our services, or upload email lists for processing through our platform.

KLEAN13 operates two distinct data relationships: as a data controller for the personal information of our own customers (account holders), and as a data processor for the email lists those customers upload to be validated, scored, and cleaned by our service.

Please read this Privacy Policy carefully. By using our services, you consent to the practices described in this policy.

Information We Collect

Information You Provide

We collect information you voluntarily provide when you:

• Create an account or sign up for a trial
• Connect integrations such as your CRM, ESP, or marketing platform
• Upload email lists for validation or hygiene processing
• Configure scheduled cleanings, API integrations, or webhook endpoints
• Contact us via email or our website
• Subscribe to our communications

This information may include:

• Contact Information: Name, email address, business address, phone number
• Business Information: Company name, website URL, role, industry
• Account Information: Login credentials, API keys, integration tokens (e.g. Keap OAuth, ESP credentials)
• Payment Information: Billing details (processed securely through our payment processor — we do not store full card numbers)

Information Collected Automatically

When you visit our website or use our dashboard, we may automatically collect:

• IP address and browser type
• Pages visited and time spent on our site
• Referring website addresses
• Device and operating system information
• API request logs and usage metrics

Email Lists Processed on Behalf of Customers

When customers upload email lists to KLEAN13 for validation, hygiene, or scoring, we process those lists as a data processor under our customers' data controller relationships with their own subscribers. Our handling of this data is governed by our Terms of Service and any applicable data processing addenda.

Data we process on behalf of customers may include:

• Email addresses uploaded for validation
• Optional metadata supplied alongside each address (name, source tag, list identifier)
• Validation results (syntax, MX, deliverability, role-account flags, honeypot indicators, disposable-domain flags)
• Scoring and engagement classifications returned by integrated intelligence layers
• Suppression and known-bad markers used to protect future submissions

How We Use Your Information

We use the information we collect to:

• Validate and clean email lists you upload to our platform
• Compute deliverability classifications and risk scores
• Operate, maintain, and improve our services
• Authenticate API requests and enforce usage limits
• Process payments and send transaction confirmations
• Communicate service updates, changes, and security notices
• Respond to your inquiries and provide customer support
• Detect, investigate, and prevent fraud, abuse, and security incidents
• Comply with legal obligations

Email Communications

We send email communications for:

• Account confirmations and security notices
• Validation completion notifications and processing summaries
• Service updates, downtime notifications, and changelog summaries
• Payment receipts and billing notices
• Responses to your inquiries

You may unsubscribe from non-essential emails by clicking the unsubscribe link in any email or contacting us directly. Operational and security communications cannot be unsubscribed from while your account is active.

Information Sharing and Disclosure

We do not sell, rent, or trade your personal information to third parties. We may share information with:

• Validation Data Providers: Third-party services that contribute to email validation (DNS lookups, MX verification, deliverability data sources). These providers receive only the data necessary to perform validation checks on the addresses you submit.
• Service Providers: Cloud hosting, payment processing, analytics, customer support, and infrastructure vendors. These providers are contractually obligated to protect your information and use it only for the purposes we specify.
• Affiliates: Other companies within the Send13, LLC family of products (including Send13 and VIP13), where doing so is necessary to provide the services you've requested.
• Connected Integrations: Where you authorize KLEAN13 to integrate with third-party platforms (such as Keap, your ESP, or your CRM), validation results and cleaned lists may be written back to those platforms in accordance with your configuration.
• Legal Requirements: When required by law, court order, subpoena, or governmental authority, or to protect our rights, property, or safety, or that of others.
• Business Transfers: In connection with a merger, acquisition, financing, or sale of assets, your information may be transferred as part of that transaction.

Data Security

We implement appropriate technical and organizational measures to protect personal information, including:

• TLS encryption in transit for all API, dashboard, and upload traffic
• SHA3-256 hashing of recipient identifiers at the engagement intelligence layer
• Access controls, authentication, and audit logging
• Network isolation between processing infrastructure and public-facing services
• Routine review of dependencies, secrets, and infrastructure
• Encrypted backups with periodic restore testing

While we strive to protect your information, no method of transmission over the Internet or electronic storage is 100% secure. We cannot guarantee absolute security.

Data Retention

We retain personal information for as long as necessary to:

• Provide our services and maintain your account
• Maintain validation history and known-bad / suppression lists that protect future submissions
• Compute and serve scoring and classification outputs over rolling time windows
• Comply with legal, accounting, and reporting obligations
• Resolve disputes and enforce our agreements

Customer-uploaded email lists are retained only as long as necessary to complete the validation or hygiene operation requested, and to support the historical reporting features of your account. You may request deletion of uploaded lists at any time through your account settings or by contacting us. Hashed identifiers, validation outcomes, and aggregate statistics may be retained for the purpose of supporting ongoing scoring, suppression, and abuse-prevention.

International Data Transfers

KLEAN13 operates infrastructure primarily in the United States. If you access our services from outside the United States, your information may be transferred to, stored, and processed in the United States. Where required by law, we rely on appropriate safeguards such as Standard Contractual Clauses for international transfers of personal data.

Your Rights

Depending on your location, you may have the right to:

• Access the personal information we hold about you
• Request correction of inaccurate information
• Request deletion of your personal information
• Object to or restrict processing of your information
• Opt out of certain communications
• Request a copy of your data in a portable format
• Withdraw consent where processing is based on consent

For requests concerning email addresses contained within a list uploaded by a KLEAN13 customer, please contact that customer directly — they are the data controller for the list. We will refer such requests to the relevant customer where appropriate.

To exercise rights regarding your own KLEAN13 account information, contact us using the information below. We may need to verify your identity before responding.

California Privacy Rights

California residents have additional rights under the California Consumer Privacy Act (CCPA) and California Privacy Rights Act (CPRA), including the right to know what personal information is collected, request deletion, correct inaccurate information, and opt out of the sale or sharing of personal information. We do not sell personal information.

Continued use of our services after the effective date constitutes acceptance of the updated policy.
