Privacy Policy

Last updated: October 9, 2026

This Privacy Policy explains how Jessie Elizondo d/b/a Harmonic Marketing ("Harmonic Marketing," "we," "us," or "our") collects, uses, shares, and protects information when you visit harmonicmktg.com (the "Website"), work with us as a client, or authorize our application, Harmonic Marketing Ads Tool (the "App"), to access your Google account.

1. Information we collect

Information you give us

When you email us or engage our services, we collect the information you choose to share, such as your name, business name, email address, phone number, and details about your marketing needs.

Website usage information

The Website does not use advertising or analytics cookies. Our hosting provider may automatically log basic technical information (such as IP address, browser type, and pages requested) for security and reliability purposes.

Google user data accessed through the App

When you or your organization authorize the App using Google Sign-In, we request only the permissions needed to provide our services:

  • Basic account information (your name, email address, and profile image) to identify the person who authorized access.
  • Google Ads data through the Google Ads API (https://www.googleapis.com/auth/adwords scope), including account and campaign structure, campaign settings, budgets, bids, keywords, ads, audiences, and performance metrics (such as impressions, clicks, cost, and conversions) for the Google Ads accounts you have authorized.

We do not request access to Gmail, Google Drive, Google Contacts, or any other Google service.

2. How we use information

We use the information we collect to:

  • Respond to inquiries and provide, manage, and bill for our marketing services;
  • Communicate with clients about their accounts and projects.

We use Google user data obtained through the App only to:

  • Read campaign and performance data to analyze results and build reports for the client who owns the account;
  • Create, update, pause, or otherwise manage campaigns, budgets, bids, keywords, and ads when authorized by that client;
  • Monitor account health and alert the client or our team to issues.

We do not use Google user data for advertising, to build user profiles, or for any purpose unrelated to providing the services our clients have requested.

3. Use of AI services

The App uses an AI model provided by Anthropic (Claude), accessed through Anthropic's commercial API, to help analyze Google Ads data, draft reports, and prepare campaign changes. Only the data needed for a given task is sent to the AI service. Under Anthropic's commercial terms, data sent through the API is not used to train Anthropic's models.

We do not use Google user data to develop, improve, or train generalized or non-personalized AI or machine-learning models.

4. Google API Services User Data Policy (Limited Use)

Harmonic Marketing Ads Tool's use and transfer to any other app of information received from Google APIs will adhere to the Google API Services User Data Policy, including the Limited Use requirements. Specifically, we:

  • Use Google user data only to provide or improve the user-facing features of the App described in this policy;
  • Transfer Google user data to others only as needed to provide those features, to comply with applicable law, or as part of a merger, acquisition, or sale of assets with notice to users;
  • Do not use or transfer Google user data for serving advertisements, including retargeting, personalized, or interest-based advertising;
  • Do not sell Google user data, and do not use it to determine credit-worthiness or for lending purposes;
  • Do not allow humans to read Google user data, except with the user's affirmative consent, when necessary for security purposes or to comply with law, or when the data is aggregated and anonymized for internal operations. Reviewing a client's campaign data to perform the services that client hired us for is done with that client's consent.

5. How we share information

We do not sell or rent personal information or Google user data. We share information only:

  • With the client who owns the data, for example in reports and dashboards;
  • With service providers that help us operate, under confidentiality and data protection obligations: Google Cloud (application hosting and infrastructure), Anthropic (AI processing, as described above), Google Workspace (email and documents), and our website host;
  • When required by law, such as to respond to a subpoena or court order, or to protect our rights, safety, or property;
  • In a business transfer, such as a merger or sale of assets, with notice to affected users.

6. Data storage, security, and retention

Google user data is transmitted using encryption in transit (TLS). OAuth access and refresh tokens are stored encrypted, and access is limited to authorized Harmonic Marketing personnel. We store only the data needed to provide our services. Reports and summaries we prepare for a client may be kept as part of that client's records.

We retain Google user data only as long as needed to provide services to the client. When a client relationship ends, or when access to the App is revoked, we delete stored OAuth tokens and any raw Google Ads data we hold within 30 days, unless we are required by law to keep it longer.

No method of transmission or storage is completely secure, but we use reasonable administrative, technical, and physical safeguards to protect your information.

7. Your choices and rights

  • Revoke access: You can remove the App's access to your Google account at any time from your Google Account permissions page. You can also remove our access from within Google Ads under Admin → Access and security.
  • Request deletion or a copy: Email us at jessie@harmonicmktg.com to request access to, correction of, or deletion of your information. We will respond within 30 days.

Depending on where you live, including Texas under the Texas Data Privacy and Security Act, you may have additional rights regarding your personal data. Contact us to exercise them.

8. Children's privacy

Our Website, services, and App are intended for businesses and are not directed to children under 13. We do not knowingly collect personal information from children.

9. Changes to this policy

We may update this Privacy Policy from time to time. We will post the updated version on this page with a new "Last updated" date. If we make material changes to how we use Google user data, we will notify affected users and obtain consent where required.
