Effective Date: June 25, 2026
Last Updated: June 25, 2026

1. Acceptance of Terms

By accessing or using Cass, or any related website, application, integration, communication workflow, or paid plan (together, the "Service"), you agree to be bound by these Terms of Use ("Terms"). If you do not agree to these Terms, do not use the Service.

These Terms form a legally binding agreement between you ("User," "you") and Marek Dąbrowski, conducting business as AdLume, registered in Poland, NIP: 1133071063, with registered address at ul. Stawki 2a/38, 00-193 Warsaw, Poland ("Cass," "we," "us," "our").

If you use the Service on behalf of a company, agency, client, or other organization, you confirm that you are authorized to accept these Terms and connect the relevant accounts on its behalf. If you use the Service as an individual, you confirm that you are at least 18 years old and legally able to enter into this agreement.

2. Description of the Service

Cass provides Cass: an AI performance marketer for paid ads and marketing operations. Cass may work inside communication tools such as Slack, Teams, Telegram, WhatsApp, and other supported channels, and may connect with ad platforms, analytics tools, tag management tools, ecommerce tools, email tools, and other marketing systems.

Depending on your plan, configuration, connected accounts, and approved operating scope, the Service may:

• connect to supported ad and marketing tools through OAuth, APIs, or other authorization flows;
• analyze campaign, analytics, tracking, landing page, ecommerce, and business context data;
• provide campaign checks, recommendations, summaries, weekly plans, and optimization ideas;
• prepare or perform approved repeatable actions;
• perform scheduled or recurring tasks inside an approved operating scope;
• ask for approval before actions that materially affect budget, billing, campaign status, tracking or conversion measurement, account permissions, or other high-impact settings, unless you have expressly enabled such actions in a written or otherwise recorded scope.

Cass is not a guaranteed performance service, media buying guarantee, legal advisor, financial advisor, or substitute for professional judgment. You remain responsible for your advertising strategy, budget, connected accounts, business decisions, and the results of acting on or ignoring outputs from the Service.

3. Accounts and Eligibility

To use the Service, you may need to create an account and provide accurate information, including your name, email address, business or project information, and payment details.

You are responsible for:

• keeping your login credentials secure;
• ensuring that your account information is accurate and up to date;
• ensuring that you have the right to connect any ad account, analytics account, website, store, communication workspace, or other tool you connect to the Service;
• all activity that occurs through your account, connected integrations, or approved operating scope.

Notify us immediately at hello@heycass.co if you suspect unauthorized access or misuse.

4. Connected Accounts and Permissions

The Service may connect to third-party services such as Google Ads, GA4, Search Console, Google Tag Manager, Google Merchant Center, LinkedIn Ads, Microsoft Ads, Amazon Ads, X Ads, Snapchat Ads, Shopify, Klaviyo, Slack, Teams, Telegram, WhatsApp, Twilio, and other supported tools. Meta Ads is currently marked as planned or coming soon unless explicitly enabled for your account.

By connecting a third-party account, you authorize Cass to access, process, and, where enabled, act on data from that account for the purpose of providing the Service. This may include campaign data, performance metrics, account settings, landing page or tracking context, communication messages related to the Service, and other data needed to run the features you enable.

We do not ask you to share Google passwords or other third-party account passwords. Where available, access is granted and revoked through the relevant provider's OAuth, API, workspace, or authorization system.

You can revoke third-party access through the relevant provider account settings or through the Service where supported. Revoking access may limit or disable parts of the Service.

5. Automation, Approvals, and Operating Scope

Cass may perform recurring, repeatable, or scheduled actions within the operating scope that you approve or enable. Examples may include campaign checks, search term cleanup, monitoring, reporting, preparation of experiments, and other low-risk or pre-approved tasks.

Actions that materially affect budget, billing, campaign launch or pause status, tracking or conversion measurement, account permissions, or other high-impact settings require separate approval unless you have expressly enabled them in a written or otherwise recorded scope.

You are responsible for:

• reviewing and approving the operating scope before enabling automation;
• setting appropriate limits and permissions in connected tools;
• monitoring the Service's outputs and actions;
• ensuring that any automated or assisted action is appropriate for your business, budget, legal obligations, advertising policies, and risk tolerance.

Cass may refuse, pause, or require additional approval for actions that appear risky, ambiguous, unsupported, unlawful, abusive, or likely to violate a third-party platform policy.

6. Payments, Plans, Auto-Renewal, and Cancellation

Prices and plan details are shown on our website, checkout page, or order flow. Unless stated otherwise, prices are in USD and exclude applicable taxes, VAT, duties, or fees, which may be added based on your location and payment method.

6.1 7-day Optimization

The launch entry plan is 7-day Optimization at $10 for the first week. Unless you cancel before the end of the first week, your access automatically renews into the Pro plan at $89 per month.

6.2 Pro and Yearly Plans

The Pro plan is billed at $89 per month unless you choose another billing option. If you choose the yearly option, the advertised equivalent price may be $69 per month, billed yearly, or another price shown at checkout.

6.3 Auto-Renewal

By purchasing a recurring plan, you authorize Cass and its payment provider to charge your payment method on a recurring basis until you cancel. Renewal terms, billing frequency, price, and taxes will be shown at checkout or in your plan details.

6.4 Cancellation

You may cancel your recurring plan at any time through account settings, the checkout/customer portal where available, or by contacting hello@heycass.co. Cancellation stops future renewals but does not automatically remove your connected accounts or delete your data. Data deletion is handled under our Privacy Policy.

6.5 Price Changes

We may change plan prices or features in the future. Price changes for existing recurring plans will apply only after notice, unless the change is required by law, tax rules, payment processor requirements, or a change you request.

7. 30-Day Money-Back Guarantee

Cass offers a 30-day money-back guarantee. If you buy the Service and decide within 30 days that Cass did not give you useful campaign work, recommendations, approved fixes, or operational value, you may request a refund by contacting hello@heycass.co.

We may refuse or limit refunds where we reasonably believe there is fraud, abuse, repeated refund misuse, chargeback abuse, violation of these Terms, or unlawful activity. This guarantee does not limit any non-waivable consumer rights you may have under applicable law.

Refunds are processed through our payment provider and may take several business days to appear on your payment method.

8. Acceptable Use

You agree not to:

• connect accounts you do not own or are not authorized to manage;
• use the Service to violate advertising platform policies, privacy laws, intellectual property rights, or other applicable laws;
• use the Service to generate or publish unlawful, discriminatory, misleading, harmful, or abusive advertising content;
• attempt to reverse engineer, decompile, scrape, overload, or interfere with the Service;
• bypass usage limits, security controls, approval flows, or access restrictions;
• resell, sublicense, or make the Service available to third parties without our written consent;
• use the Service to process sensitive personal data unless we have explicitly agreed to that use case in writing.

We may suspend or terminate access if we reasonably believe your use violates these Terms, creates risk for Cass, other users, third-party platforms, or the public, or may expose us to legal, security, or reputational harm.

9. Your Data and Content

You retain ownership of data, content, account information, campaign information, business context, and other materials you provide or connect to the Service ("Your Data").

You grant Cass a limited, non-exclusive, worldwide license to access, process, transmit, store, analyze, and display Your Data only as needed to provide, secure, maintain, improve, and support the Service, comply with law, and enforce these Terms.

You are responsible for ensuring that Your Data is accurate, lawful, and provided with all required rights, notices, consents, and permissions.

10. Cass Intellectual Property

The Service, including software, workflows, prompts, user interfaces, designs, trade names, trademarks, documentation, and underlying technology, is owned by Cass or its licensors. These Terms do not transfer any Cass intellectual property rights to you.

You may use the Service only as allowed under these Terms and your active plan.

11. AI Outputs and Advertising Results

The Service uses artificial intelligence and automated analysis. AI outputs may be incomplete, inaccurate, outdated, or inappropriate for your specific business, account, legal obligations, or advertising policies.

You acknowledge and agree that:

• recommendations, summaries, and suggested actions are not guarantees;
• Cass does not guarantee improved ROAS, CPA, conversion volume, revenue, leads, sales, account health, platform approval, or other advertising or business outcomes;
• you are responsible for deciding whether to enable automation, approve actions, follow recommendations, pause actions, or adjust operating scope;
• advertising platforms may change performance, policies, account status, auctions, attribution, and delivery in ways outside Cass's control.

To the maximum extent permitted by law, Cass is not responsible for advertising spend, budget changes, performance changes, lost profit, lost revenue, failed campaigns, platform disapprovals, or business outcomes resulting from your use of or reliance on the Service.

12. Third-Party Services

The Service may integrate with third-party services. Your use of those services is governed by their own terms and policies. Cass is not responsible for third-party services, outages, API changes, authorization failures, policy decisions, platform enforcement, billing, data accuracy, or changes made by third-party providers.

If a third-party service changes or disables an API, permission, policy, integration, or account, parts of the Service may stop working or require reconfiguration.

13. Service Availability and Changes

We may modify, suspend, or discontinue parts of the Service at any time. We will try to provide reasonable notice for material changes that negatively affect paid users, but we may act without notice where needed for security, legal, technical, platform, or abuse-prevention reasons.

The Service is provided "as is" and "as available." We do not warrant that the Service will be uninterrupted, error-free, secure, or compatible with every account, campaign structure, browser, device, workflow, or third-party platform.

14. Limitation of Liability

To the maximum extent permitted by applicable law, Cass and its owner, contractors, partners, and suppliers will not be liable for indirect, incidental, special, consequential, exemplary, or punitive damages, including lost profits, lost revenue, lost data, lost goodwill, advertising spend, or business interruption.

To the maximum extent permitted by applicable law, our total liability for any claim arising out of or relating to these Terms or the Service will not exceed the amount you paid to Cass in the three (3) months before the event giving rise to the claim.

Nothing in these Terms limits liability where such limitation is not allowed by applicable law.

15. Termination

You may stop using the Service at any time. We may suspend or terminate your access if:

• you violate these Terms;
• payment fails or chargebacks occur;
• your use creates security, legal, platform, or reputational risk;
• you connect accounts without authorization;
• we are required to do so by law or a third-party platform.

After termination, your right to use the Service stops immediately. You may request data export or deletion by contacting hello@heycass.co, subject to legal retention requirements and technical limitations described in our Privacy Policy.

16. Consumer Rights

If you use the Service as a consumer, you may have non-waivable rights under the laws of your country of residence. Nothing in these Terms limits those rights.

If you are a consumer resident in the European Union, you may also use the EU Online Dispute Resolution platform at https://ec.europa.eu/consumers/odr, if applicable.

17. Changes to These Terms

We may update these Terms from time to time. If changes materially affect your rights or active paid plan, we will provide reasonable notice by email, in-app message, website notice, or another appropriate method. Your continued use of the Service after the effective date of updated Terms means you accept the updated Terms.

18. Governing Law and Dispute Resolution

These Terms are governed by the laws of Poland, without prejudice to any non-waivable consumer protections that may apply in your country of residence.

Any disputes arising under these Terms will be subject to the competent courts in Warsaw, Poland, unless applicable consumer law gives you the right to bring a claim in another jurisdiction.
