Terms of Service

Last updated: August 1, 2026

These Terms of Service (“Terms”) govern your use of Fluxchek (the “Service”), operated by Inboxcraft Online Agency (“we,” “us,” “our”), a business registered in the Philippines. By creating an account or using the Service, you agree to these Terms.

1. Description of Service

Fluxchek connects to a user's Klaviyo account (via a private API key the user provides) and generates a scored audit of that account's email flows, list hygiene, and deliverability signals. Scores and findings are generated by an automated, rule-based scoring system.

2. Accounts

You must provide accurate information when creating an account and are responsible for maintaining the confidentiality of your login credentials. You are responsible for all activity that occurs under your account.

3. Your Klaviyo API Key

When you run a scan, you provide your own Klaviyo private API key. By doing so, you represent that you are authorized to use that key (e.g. it is your own account, or you have permission from the account owner, such as a client, to run this scan on their behalf). We use this key only to perform the requested scan and do not store it — see our Privacy Policy for details.

You are solely responsible for the scope of access you grant via the API key you provide.

4. Subscriptions and Billing

Fluxchek offers a Free plan and paid subscription plans (Starter, Agency), as described on our Pricing page. Paid plans are billed on a recurring monthly basis.

Payment processing. All payments are processed by Lemon Squeezy, who acts as the merchant of record for these transactions. Your purchase is subject to Lemon Squeezy's Buyer Terms and Conditions in addition to these Terms.

Cancellation.You may cancel your subscription at any time through your account's subscription management page. Cancellation takes effect at the end of your current billing period; we do not provide prorated refunds for partial billing periods except as described below.

Refunds.If you have not exceeded your plan's monthly scan limit, you may request a full refund within 7 days of your purchase or renewal date by contacting support@fluxchek.com. Refund requests made after 7 days, or after your plan's scan limit has been used, will not be eligible for a refund.

Plan limits. Each plan includes a monthly scan limit and a maximum number of connected Klaviyo accounts, as described on our Pricing page. These limits reset at the start of each calendar month and are enforced automatically.

5. Acceptable Use

You agree not to:

  • Use the Service to access Klaviyo accounts you are not authorized to access
  • Attempt to circumvent plan limits, quotas, or paywalls
  • Use the Service for any unlawful purpose
  • Attempt to reverse-engineer, scrape, or resell the Service without our permission
  • Interfere with or disrupt the integrity or performance of the Service

We reserve the right to suspend or terminate accounts that violate these Terms.

6. Intellectual Property

The Service, including its scoring methodology, design, and content (excluding your own Klaviyo account data), is owned by us. Reports generated from your own Klaviyo account data are yours to use, including sharing with your own clients.

7. Disclaimer of Warranties

The Service is provided “as is” and “as available,” without warranties of any kind, whether express or implied. We do not guarantee that the Service will be uninterrupted, error-free, or that scan results will be complete or fully accurate — scores and findings are generated algorithmically and are intended as a diagnostic aid, not professional certification.

8. Limitation of Liability

To the maximum extent permitted by law, we shall not be liable for any indirect, incidental, special, or consequential damages arising from your use of the Service, including but not limited to loss of revenue, data, or business opportunities.

9. Termination

We may suspend or terminate your access to the Service at any time for violation of these Terms. You may stop using the Service and cancel your subscription at any time.

10. Changes to These Terms

We may update these Terms from time to time. Continued use of the Service after changes are posted constitutes acceptance of the revised Terms.

11. Governing Law

These Terms are governed by the laws of the Republic of the Philippines, without regard to conflict of law principles.
