These Terms of Service (the “Terms”) govern your access to and use of Mediation One (the “Service”), operated by the Mediation One team (“we”, “us”). By creating an account or uploading data you agree to these Terms. If you do not agree, do not use the Service.

1. The Service

Mediation One ingests ad-revenue data you provide (CSV uploads or API integrations) and produces diagnostics, anomaly detection, and recommended actions. The Service is informational. You are solely responsible for any change you apply to your ad stack based on our recommendations.

2. Accounts

You must provide accurate information when creating an account and keep your credentials secure. You are responsible for all activity under your account. We may suspend accounts that violate these Terms or applicable law.

3. Plans, billing and trials

Paid plans are billed monthly in advance through Lemon Squeezy, which acts as our Merchant of Record (it issues your invoice and collects applicable sales tax / VAT / JCT on our behalf). By starting a paid plan you authorize Lemon Squeezy to charge the payment method on file at the start of each billing period until you cancel. Prices are listed on our pricing page and may change with at least 30 days notice for existing subscribers.

The performance add-on, if elected, bills a percentage of verified uplift measured by the Service. The measurement methodology is described in our documentation and is applied uniformly across customers.

4. Your data

You retain all rights to the data you upload. You grant us a limited, non-exclusive license to process that data solely to operate the Service for you. We do not sell your data and we do not aggregate your data across customers for the benefit of other customers without explicit opt-in.

5. Acceptable use

You will not (a) reverse engineer the Service, (b) attempt to access another customer’s data, (c) use the Service to violate ad-network policies on your behalf, or (d) upload data you do not have the right to provide.

6. Third-party services

The Service integrates with third-party platforms (Lemon Squeezy as Merchant of Record for billing, Resend for email, Slack and Telegram for notifications, optionally OpenAI-compatible LLM providers). Your use of those services is governed by their own terms.

7. Warranty disclaimer

The Service is provided “as is” without warranties of any kind. We do not warrant that the Service will increase your revenue or that any specific recommendation will produce a specific result.

8. Limitation of liability

To the maximum extent permitted by law, our aggregate liability for any claim arising from or related to the Service is limited to the amount you paid to us in the 12 months preceding the claim. We are not liable for indirect, incidental, or consequential damages, including lost ad revenue.

9. Termination

You may cancel at any time from the billing portal. We may terminate or suspend access if you breach these Terms. Sections 4, 7, 8 and 10 survive termination.

10. Governing law and contact

These Terms are governed by the laws of Japan. For any question about these Terms, contact hello@mediation.one.
