Terms of Service

These Terms of Service ("Terms") govern your use of the Ad-Efficiency platform, MCP connector, website and related services (together, the "Service"), provided by Serann Limited, a company registered in England & Wales (Company No. 13457476; registered office 182-184 High Street North, Office 16521, East Ham, London, E6 2JA, United Kingdom) ("Serann", "we", "us", "our"). By creating an account, connecting a platform, or otherwise using the Service, you agree to these Terms.

1. The Service

Ad-Efficiency is a software platform and MCP (Model Context Protocol) connector for planning, monitoring and optimising paid advertising campaigns across supported platforms. The Service performs agency-level execution on connected ad accounts, including recommendations, diagnostics and automated workflows, but any change to a connected ad account is executed only after your explicit approval, unless you have separately configured a defined, bounded automation rule and consented to it in writing.

2. Accounts and eligibility

The Service is intended for business use by advertisers, in-house teams, agencies and freelancers. You must be at least 18 years old and authorised to bind the entity you represent. You are responsible for keeping your login credentials secure and for all activity that occurs under your account. Notify us promptly if you suspect unauthorised access.

3. Your ad accounts and your responsibilities

• You retain ownership and control of your advertising accounts. The Service operates via OAuth tokens or credentials you provide and can be disconnected at any time.
• You are responsible for the content of your ads, the products or services being advertised, and compliance with the policies of Google, Meta, TikTok, Microsoft, Amazon and any other advertising platform you connect.
• You are responsible for reviewing and approving proposed changes before they are applied.
• You are responsible for complying with all laws that apply to your business, including advertising, consumer, data protection and competition law.

4. Our responsibilities and service levels

We will use commercially reasonable efforts to make the Service available, to keep it secure, and to deliver the features described on our website and in your subscription plan. We will notify you in advance of scheduled maintenance where practical.

We do not guarantee any specific advertising outcome. Ad performance depends on factors outside our control, including your creative, offer, market conditions, platform algorithm changes and competitor activity, and results will vary. Historical case-study figures on our website reflect specific past engagements and are not a prediction of future results.

5. Acceptable use

You agree not to, and not to allow any third party to:

• Use the Service to violate any law, third-party right, or advertising platform policy;
• Reverse engineer, decompile, disassemble or attempt to derive the source code of the Service, except as permitted by mandatory law;
• Resell, sublicense or provide the Service to third parties as a standalone offering without a written agreement with us;
• Interfere with, probe, or attempt to disrupt the security or integrity of the Service;
• Upload malware, illegal content, or content that infringes third-party rights;
• Use the Service to send unsolicited communications or to run campaigns that violate anti-spam or consumer protection laws.

6. Fees, billing and pricing

• Subscriptions are billed monthly or annually in advance, in the currency shown at checkout.
• You may cancel at any time. Cancellation takes effect at the end of your current billing period; you retain access until then. We do not pro-rate refunds for time already used unless required by law.
• Fees are exclusive of VAT and any other applicable taxes, which will be added where required.
• Founding pricing lock: where a plan is marketed as founding pricing, the price you sign up at is locked for as long as your subscription remains continuously active on that plan. If you downgrade, cancel or let payment lapse, the founding rate is forfeited and re-subscription is at the then-current standard price.
• We may change standard pricing on notice of at least 30 days for existing subscriptions; any change applies to renewals after the notice period.

7. Intellectual property

The Service, including all software, models, prompts, documentation, design, and trademarks, is owned by Serann Limited and its licensors and is protected by intellectual property laws. We grant you a limited, non-exclusive, non-transferable, revocable licence to use the Service in accordance with these Terms during your subscription.

Your data. You retain all rights in your ad accounts, creative, campaign data and any content you submit. You grant us a limited licence to process that data solely to provide, secure and improve the Service in accordance with our Privacy Policy. We do not claim ownership of your advertising data. For advertising-platform data that you (or your agency) connect to the Service, Serann acts as a data processor on your behalf and on your documented instructions; business and agency customers may request a Data Processing Agreement (DPA) at privacy@ad-efficiency.com.

8. Confidentiality

Each party will protect the other's confidential information with the same degree of care it uses for its own confidential information, and will not disclose it except to personnel and subprocessors who need to know it and are bound by confidentiality obligations.

9. Disclaimers

The Service is provided "as is" and "as available". To the maximum extent permitted by law, we disclaim all warranties, express or implied, including implied warranties of merchantability, fitness for a particular purpose, non-infringement and uninterrupted or error-free operation. We do not warrant that use of the Service will increase revenue, reduce cost, or achieve any other business outcome.

10. Limitation of liability

To the maximum extent permitted by law:

• Neither party will be liable for any indirect, incidental, special, consequential or punitive damages, or for loss of profits, revenue, goodwill or data, even if advised of the possibility.
• Our total aggregate liability arising out of or relating to these Terms or the Service in any 12-month period is limited to the fees you actually paid us for the Service in the 12 months preceding the event giving rise to the claim.
• Nothing in these Terms limits liability for death or personal injury caused by negligence, for fraud or fraudulent misrepresentation, or for any other liability that cannot be limited under English law.

11. Indemnity

You will indemnify and hold harmless Serann Limited from third-party claims arising out of (a) your use of the Service in breach of these Terms; (b) your content, ads or offers; or (c) your breach of advertising platform policies or applicable law.

12. Termination

You may terminate by cancelling your subscription in-product or by writing to us. We may suspend or terminate your access if you materially breach these Terms and do not cure the breach within 14 days of notice, or immediately if the breach is not curable, involves illegal activity, or presents a security risk. On termination, your right to use the Service ends and, upon request, we will delete your data in accordance with our Data Deletion process.

13. Changes to these Terms

We may update these Terms. Material changes will be notified in-product or by email at least 30 days before they take effect. Continued use of the Service after the effective date constitutes acceptance.

14. Governing law and jurisdiction

These Terms are governed by the laws of England and Wales. The courts of England and Wales have exclusive jurisdiction over any dispute arising out of or relating to these Terms or the Service, except that either party may seek injunctive relief in any competent court to protect its intellectual property or confidential information.

15. General

If any provision of these Terms is held unenforceable, the remaining provisions will remain in effect. Our failure to enforce a right is not a waiver. You may not assign these Terms without our written consent; we may assign them to an affiliate or in connection with a merger, acquisition or sale of assets. These Terms are the entire agreement between you and us regarding the Service and supersede any prior agreement on the same subject.
