Legal
Terms of Service
Effective October 10, 2026
These terms apply to the SameSpend advertising analysis service operated by ARCS AI (マイアークス株式会社), Tokyo, Japan. A signed agreement, quote or order form with a client takes precedence over these terms where they differ.
1. The service
We analyze advertising performance data that a client gives us access to and provide reports and recommendations. Recommendations are based on historical data and do not guarantee future results. Projections on our website and in our reports are labelled as such.
2. Free audit
The free audit has no cost and no obligation. We may decline an audit request, for example when an account has too little data to analyze responsibly.
3. Fees and payment
Paid services are billed at the price stated in your quote: a one-time fee for a deep audit and/or a flat monthly fee for ongoing service. Fees are never calculated as a percentage of your ad spend. Payments are processed by Stripe. Monthly service renews each month until cancelled and can be cancelled at any time, effective at the end of the current paid month. Advertising platform charges (Google, Meta) are billed to you directly by those platforms and are not part of our fees.
4. Client responsibilities
The client confirms that it is authorized to grant us access to the advertising accounts and records it shares, and remains responsible for its accounts, budgets and compliance with the advertising platforms' policies.
5. Changes to campaigns
We do not change a client's campaigns unless the client has approved the specific change in writing. The client can revoke our access at any time from its advertising account settings.
6. Confidentiality and data
We treat client data as confidential and handle it as described in our Privacy Policy. We will only publish a client's results as a case study with the client's permission, and without identifying details unless the client agrees otherwise.
7. Limitation of liability
To the extent permitted by law, we are not liable for indirect or consequential losses, and our total liability is limited to the fees paid for the service in the three months before the claim.
