Last Updated: August 2, 2026

Welcome to SirSync. These Terms of Use (“Terms”) govern your access to and use of sirsync.com, the SirSync Free plugin, the SirSync Pro plugin, and any related services (collectively, the “Services”). By accessing our website, creating an account, purchasing a license, or using SirSync, you agree to these Terms. If you do not agree to these Terms, please do not use SirSync.

Eligibility

You must be at least 13 years old to use SirSync. If you are using SirSync on behalf of a company or organization, you represent that you have authority to bind that organization to these Terms.

Accounts

Some features require a SirSync account. You are responsible for:
  • Maintaining the confidentiality of your account credentials.
  • All activity that occurs under your account.
  • Keeping your account information accurate and up to date.
You may delete your account at any time through your account dashboard.

Licensing

SirSync Free is available under the GNU General Public License (GPL). SirSync Pro requires a valid license for advanced features. An active Pro license is required to access Pro functionality. When a license expires:
  • Previously synchronized content remains on your websites.
  • SirSync Pro features are disabled.
  • Free features remain available.

License Plans

SirSync licenses are based on connected site pairs. Current plans include:
  • Solo – One connected site pair
  • Standard – Three connected site pairs
  • Agency – Ten connected site pairs
A connected site pair typically consists of two WordPress installations, such as a staging website and a production website. Agency licenses may be used across multiple client websites within the licensed site pair limit. Customers may deactivate existing site pairs and activate new ones through their account dashboard.

Permitted Use

You may:
  • Install SirSync on websites covered by your license.
  • Use SirSync for personal, commercial, or client projects.
  • Deploy content between connected websites.

  • Reverse engineer license validation or activation systems.
  • Share, resell, sublicense, or distribute SirSync Pro.
  • Misrepresent ownership of SirSync.
  • Use SirSync in violation of applicable laws.
Attempts to bypass licensing or abuse the licensing system may result in immediate license termination.

Updates

Active Pro licenses receive access to plugin updates during the subscription period. SirSync may discontinue support for older versions of WordPress, PHP, or third-party software as technology evolves.

Renewals

SirSync Pro licenses renew automatically unless canceled. Customers may cancel automatic renewal at any time through their account. Canceling renewal does not immediately deactivate the license. Your license remains active until the current subscription period expires.

SirSync offers a 30-day money-back guarantee for initial Pro license purchases. Refunds:
  • Apply only to the initial purchase.
  • Do not apply to renewals.
  • Do not apply to license upgrades.
  • Are limited to one refund per purchase.
Eligible refunds may be requested directly from your customer account. Once a refund is processed:
