What changed on 12 October 2026: Google Ads changes an AI app proposes together can be approved as one group after you review them (except changes that can raise spend or reach), and an AI app can save a scheduled rule, switched off until someone signed in to the console switches it on (Sections 1 and 3).
What changed on 10 October 2026: for now, every change is approved in the Ad-Efficiency console. Approving a change in your AI app or in Slack is paused, and after their first run automatic product labels wait for your approval each day (Sections 1 and 3).
What changed on 6 October 2026: the Service can now read and host product feeds and rewrite product titles and descriptions in bulk and run title tests, each with your approval (Sections 1, 3 and 5).
What changed on 5 October 2026: Google Merchant Center accounts can now receive changes too, with the same approval as Google Ads; and some features, such as automatic product labels, run as a recurring rule that you approve once and that then runs every day until you pause or stop it (Sections 1 and 3).
What changed on 1 October 2026: you now connect each platform separately; Google Ads accounts can receive changes, each made only with your approval, given in the Ad-Efficiency console or in your AI app (approval in an AI app is paused since 10 October 2026); and you can invite someone to connect their own account with a share link.
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 LLC, a limited liability company registered in Wyoming, USA (filing ID 2026-002089734; principal office 30 N Gould St Ste N, Sheridan, WY 82801, United States) ("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 reads your connected accounts to provide audits, reports, monitoring and recommendations. For Google Ads and Google Merchant Center accounts where you switch on Changes, it can also make changes, only with your explicit approval, given in the Ad-Efficiency console: one change at a time or, for changes proposed together as a batch, all of them at once after you review them, except changes that can raise spend or reach, which are approved one by one. Each change is still checked and applied on its own. Approving a change in the AI app you connected, or in Slack, is paused for now; we will update these Terms before we switch it on again.
Some features run as a recurring rule: you approve the rule once, in the Ad-Efficiency console, and it then makes the changes it describes every day, within the limits shown to you when you approved it, until you pause or stop it (see Section 3). For now, after its first run, each day's changes wait for your approval in the console. We never make a change that you have not approved, either on its own or as part of a rule.
The Service can also host product feeds: it reads products from a shop, file or sheet you add, applies the rules you save, and publishes a file for each channel you choose. Reading a feed changes nothing in your shop or your source file.
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.
- Before approving a change, check it. When you use Approve all on a batch, you approve each change it applies to. When you approve a change, it is made in your account and you are responsible for it, and for its effect on spend and performance, as if you had made it yourself in the ad platform. The Service refuses some changes to limit mistakes (for example a budget change of more than 50% in one step). These limits are a safety net, not a review of whether a change is right for your business.
- Recurring rules. When you approve a recurring rule (for example automatic product labels in Google Merchant Center), you approve every change it makes while it is active, as described in the summary you approved, and you are responsible for those changes as if you had made them yourself. Recurring rules can only be approved, started and stopped in the Ad-Efficiency console. An AI app can propose them but cannot approve them. Every run is logged, and you can pause or stop the rule at any time and undo its latest run. For now, after the first run, every run waits for your approval in the console. Once runs may go ahead on their own again, a run that would change an unusually large part of your account (for automatic product labels: more than 30% of products, and at least 10, in one day) will still wait for your decision. Undoing a run also pauses the rule. This limit is a safety net, not a review of whether the rule is right for your business.
- Scheduled rules. An AI app can save a scheduled Google Ads rule, switched off. It runs on its schedule only after someone in your workspace with the Editor role or above switches it on in Rules in the console, or when someone runs it by hand there, and it only proposes changes, each of which waits for approval in the console like any other change.
- Product feeds. Add only shops, files and sheets that you own or are allowed to use. You are responsible for the product information, titles and descriptions in your feeds, including text your AI app wrote and you approved, and for following the rules of each channel you send them to. Channels decide whether to accept your products. Each feed file is published at an address with a random key so that channels can fetch it; anyone with the address can read it, so give it only to the channels that need it. If you give us a shop API key, use one that can only read products.
- Title tests. A title test is a change you approve: it gives new titles to half of the products you chose. Its result compares click-through rates over a limited period and is an estimate, not a promise of future results.
- Google Merchant Center has no test mode. The Service checks each Merchant Center change before sending it, but cannot test it with Google first, and Google may take some time to show the result.
- An AI app you connected can propose changes, but you approve them in the console. AI apps can make mistakes: read the summary of each change before you approve it.
- Keep personal API keys secret. Anyone who has a key can use it, with the access it was given, until you revoke it or it expires.
- Send share links only to people who are entitled to give access to the accounts concerned and who expect your request. If you connect a platform through someone else's share link, you confirm that you are allowed to give that person access to those accounts. Either side can end the connection at any time: the workspace owner in Accounts, and you in your Google account settings.
- If you connect an AI app (for example Claude, ChatGPT or Cursor) through our MCP connector, you choose that app and accept its provider's terms. Answers and suggestions written by an AI app are its own output: check them before acting on them. You can disconnect an app at any time in Settings.
- 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.
- Use share links or the Service to obtain access to accounts without the clear permission of the person entitled to grant it.
- Use hosted feeds to read websites you are not allowed to read, or to publish product information you have no right to publish.
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 LLC 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 applicable law.
11. Indemnity
You will indemnify and hold harmless Serann LLC 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 the State of Wyoming, United States, without regard to its conflict of laws rules. The state and federal courts located in Wyoming 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. Nothing in this section takes away rights you have under mandatory law where you are based.
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.
