Terms of Service

Last updated: 23 June 2026

These terms govern your use of Growth Method, both the marketing site at growthmethod.com and the product at app.growthmethod.com (together, “the Service”). The Service is operated by Growth Method Limited, a company registered in England and Wales (company number 12512334, VAT number GB 380 7638 72), with its registered office at Forest House Office, 3-5 Horndean Road, Bracknell, Berkshire, RG12 0XQ, United Kingdom (“we”, “us”, “our”).

By creating an account, signing in, or using the Service, you agree to these terms. If you don’t agree, don’t use the Service.

1. Your account

You need an account to use the product. When you sign up you agree that:

• You’re at least 18 years old.
• The information you give us is accurate and you’ll keep it up to date.
• You’re responsible for everything that happens under your account, including keeping your password secure.
• You won’t share your login with anyone else. If your team needs more access, invite them as team members.
• You’ll let us know promptly if you spot unauthorised use of your account.

We may suspend or terminate accounts that violate these terms (see Section 10).

2. Your team

Growth Method is built around teams. The person who creates a team is its first manager. Managers can invite members, change roles, and remove people. Members can use the product within the team but can’t change team-level settings.

If you’re signing up on behalf of an organisation, you confirm you have authority to bind that organisation to these terms.

3. Agency use

If you’re a marketing agency, consultancy, or service provider using Growth Method on behalf of a client, additional rules apply:

• You must have a written agreement with your client that permits you to use a third-party tool like Growth Method, to upload their data, and to share access with team members.
• You’re responsible for your client’s data. When you connect your client’s analytics accounts, upload their content, or run experiments on their behalf, you’re acting as their representative. You confirm you have authority to do so.
• You’re responsible for your team members’ access. If you give your client access as a team member, or if you give your own staff access, you’re responsible for what they do in the account.
• One team per client engagement is the expected pattern. Don’t mix multiple clients’ data into a single team. We may, at our discretion, require separation if we believe data is being commingled.
• Billing is between you and us. Your client isn’t our customer unless they sign up directly. You can’t pass our liability through to your client beyond what’s allowed in Section 14.
• If your engagement with a client ends, you must either (a) transfer the team to the client (we’ll help, email support@growthmethod.com), or (b) export their data and delete the team. Don’t keep a former client’s data in your account.

If you want to use Growth Method at scale as an agency (managing many client teams), get in touch and we’ll talk about a partner arrangement.

4. What you can and can’t do

You can use the Service for any lawful purpose related to running and analysing growth experiments for your business or your client’s business.

You agree not to:

• Use the Service to do anything illegal, harmful, or that infringes someone else’s rights.
• Try to reverse-engineer, scrape, or extract our source code or data beyond what’s available through the product itself.
• Probe, attack, or interfere with the Service’s security or availability.
• Use the Service to send spam, run phishing campaigns, or harass anyone.
• Resell, sublicense, or white-label the Service without our written permission.
• Use the Service to train competing AI models.
• Upload content you don’t have the right to upload.

5. Your data

You own your data. Anything you put into Growth Method (your experiments, ideas, metrics, comments, uploaded files) stays yours. We don’t claim ownership of it.

You grant us a limited licence to store, process, and display your data solely to provide the Service to you and your team. We use sub-processors (cloud hosting, email delivery, error tracking, AI providers) to do this. The full list is in our Privacy Policy.

You’re responsible for the legality of the data you upload. Don’t upload personal data about people who haven’t agreed to it, or anything that breaks UK GDPR, the Data Protection Act 2018, or equivalent laws in your jurisdiction.

6. Third-party integrations

Growth Method connects to third-party services like Google Analytics, Google Search Console, PostHog, Webflow, Salesforce, and others. When you connect one:

• You authorise us to access your account on that service on your behalf, limited to the scopes you grant during the connection flow.
• Depending on the integration and what you set up, this access can include reading your data, and also creating, changing, or deleting data in that connected system. We do this only to carry out the actions you’ve configured in Growth Method (see Section 7).
• We store the access tokens encrypted and use them only for the connection you’ve authorised.
• You can disconnect at any time from the integrations settings page. Disconnecting revokes our access immediately.
• We’re not responsible for the third-party service itself, its availability, or its terms. Those are between you and them.

7. AI and autonomous actions

Growth Method uses AI (currently OpenAI and Anthropic models) to score ideas, summarise experiments, suggest next steps, power in-app chat, and take actions on your connected systems on your behalf. You should know:

• AI output is suggestive, not authoritative. It can be wrong, biased, or out of date. Don’t make important business decisions based solely on AI output without your own judgement.
• We send your input to AI providers. When you use AI features, the relevant content (your ideas, metrics, chat messages) is sent to our AI providers for processing. We do not use your data to train AI models, and our AI providers are contractually prohibited from doing so. See our Privacy Policy for details.
• You’re responsible for what you do with AI output. If AI suggests a marketing claim or experiment design, you’re responsible for checking it’s accurate, legal, and on-brand before you act on it.

Actions on your connected systems. Some features let Growth Method act on the third-party systems you’ve connected (your “integrations”, see Section 6). This includes custom agents you build on the platform, which can have full read and write access to your integrations and can create, change, overwrite, or delete data in them, for example in Salesforce or your analytics tools. These actions, and the agents that take them, run from the workflows, rules, and instructions you set up and authorise. We carry them out as configured; we don’t independently decide to act on your data.

Because these actions affect live systems, you should know:

• You own the agents you build and how they’re configured. You’re responsible for the agents, automations, and instructions you set up, the access you grant them, and the effect their actions have on your connected systems, including any data that is changed, overwritten, or deleted. Your particular setup can affect what an agent does.
• Agents can act in ways you didn’t intend. An agent’s actions can be wrong or have unintended effects, just like AI output can. An action that affects connected data may not be reversible.
• Unattended agents act on your authority. Custom agents can run completely unattended, with no person reviewing each action as it happens. You take on responsibility when you build, configure, and switch on an agent, not action by action. Before you enable one on a connected system, scope its access tightly and test how it behaves, especially for actions that are hard to undo or that touch data you can’t afford to lose. Where we offer scoping, approval, or test-run controls, use them.
• Back up what matters. Keep your own backups of any data in connected systems that you can’t afford to lose. Don’t rely on Growth Method or the connected service as your only copy.

To the extent allowed by law, we’re not liable for the consequences of actions taken by agents or automations you’ve built, configured, or approved, including loss of or damage to data in your connected systems. This is subject to Sections 13 and 14.

8. Subscriptions and billing

• Billing. Subscriptions are billed in advance through our payment processor (Stripe). You can choose to pay monthly or annually.
• Automatic renewal. Your subscription renews automatically at the end of each billing period (monthly or annual) unless you cancel before the renewal date. We’ll charge the payment method on file for the next period at the then-current price for your plan.
• Pricing changes. We may change pricing for new sign-ups at any time. Existing customers will be notified at least 30 days before a change applies to them.
• No free trial. We don’t offer a free trial. If you want to see the product first, visit https://growthmethod.com and get in touch. We’ll arrange a demo.
• Cancellation. You can cancel anytime from your account settings. Cancellation takes effect at the end of your current billing period. You keep access until then.
• Refunds. We don’t pro-rate refunds for partial billing periods. If you cancel within 14 days of your first paid subscription, email support@growthmethod.com for a full refund. Refunds outside the 14-day window are at our discretion.
• Annual plan refunds. If you cancel an annual plan after the 14-day window, you keep access until the end of the annual period but don’t get a partial refund.
• Taxes. Prices exclude VAT unless stated otherwise. We’ll add VAT where required by law.
• Failed payments. If a payment fails, we’ll retry for a few days. If it keeps failing, we’ll downgrade your account to read-only access until payment is resolved.

9. Service availability

We work hard to keep the Service running, but we don’t guarantee uninterrupted access. The Service is provided “as is”. We don’t currently offer an uptime SLA. If that matters for your use case, get in touch and we’ll talk.

We may occasionally take the Service offline for maintenance. We’ll give you reasonable notice for planned downtime.

10. Termination

You can stop using the Service any time by cancelling your subscription and deleting your account from settings.

We can terminate or suspend your account if you:

• Violate these terms,
• Don’t pay,
• Use the Service in a way that harms us, other customers, or third parties,
• Or for any other reason on 30 days’ notice (we’ll refund any pre-paid unused time).

When your account is terminated:

• First 30 days (export window): your account is read-only. You can log in and export your data: experiments, ideas, metrics, comments, uploaded files.
• Days 31 to 60 (active deletion): we delete your account’s data from our active systems (databases, file storage, search indexes).
• Days 61 to 90 (backup deletion): any remaining copies in our backup snapshots roll off as those snapshots expire. After day 90, no copy of your data remains.

If you need data deleted faster than this for a legal or compliance reason, email legal@growthmethod.com and we’ll help.

These terms keep applying to anything that survives termination by nature (e.g. IP ownership, liability, indemnities).

11. Intellectual property

We own the Service: the software, design, branding, and documentation. You get a limited, non-exclusive, non-transferable licence to use it under these terms. You don’t get any rights in our trademarks, logos, or source code.

If you give us feedback, suggestions, or feature ideas, we can use them freely without owing you anything.

Your name and logo. We may identify you as a customer and use your company name and logo on our website and in marketing materials. If you’d rather we didn’t, email support@growthmethod.com and we’ll remove it.

Case studies. We may ask to publish a case study about your results with Growth Method. We’ll only do this with your written approval, and you’ll get to review and approve any quote or detail we attribute to you before it goes live.

12. Confidentiality

If we share something with you that’s marked confidential or that a reasonable person would treat as confidential (pricing discussions, roadmap, etc.), keep it confidential. The same applies the other way. We’ll treat your private business data as confidential and only share it as needed to provide the Service or where required by law.

13. Warranties and disclaimers

We provide the Service with reasonable care and skill. Beyond that, the Service is provided “as is” and “as available”, with no other warranties (express or implied), including any warranty of merchantability, fitness for a particular purpose, or non-infringement.

We don’t warrant that:

• The Service will be error-free or uninterrupted,
• AI output will be accurate,
• Agents, automations, or AI-driven actions on your connected systems will always run correctly or as you intended,
• Integrations with third-party services will keep working if those services change their APIs,
• Defects will be corrected.

Nothing in these terms limits any rights you have that can’t be limited under English law (e.g. statutory consumer rights, if they apply).

14. Limitation of liability

To the maximum extent allowed by law:

• Neither party is liable to the other for indirect, incidental, consequential, special, or punitive damages, including lost profits, lost revenue, loss of or damage to data, business interruption, or the cost of obtaining substitute services, even if it had been told these were possible.
• Subject to the exclusions above, each party’s total liability to the other for all claims relating to the Service, of any kind and whether direct or indirect, including the cost of putting right or making good (such as recovering, reconstructing, or restoring lost or damaged data), is capped at the total amount you paid us in the 12 months before the event giving rise to the claim.

These limits don’t apply to:

• Your indemnity obligations under Section 15,
• Either party’s liability that can’t be limited under English law (for example, death or personal injury caused by negligence, fraud, or fraudulent misrepresentation).

15. Indemnification

You agree to defend and indemnify us against any claims, losses, or costs arising from:

• Your breach of these terms,
• Your misuse of the Service,
• Your content infringing someone else’s rights,
• Your violation of any law in your use of the Service,
• The agents, automations, or actions you build, configure, or authorise on your connected systems, including any claim by a third party (such as your client) about data that was changed or deleted,
• If you’re an agency: any dispute between you and your client about your use of the Service on their behalf.

16. Changes to these terms

We may update these terms from time to time. When we do, we’ll update the page and change the “Last updated” date at the top. If a change is material, we’ll show a notice in the app.

Your continued use of the Service after a change takes effect means you accept the updated terms. If you don’t accept a change, stop using the Service and cancel your account.

We track which version of the terms you accepted at signup, so we can always tell you what you agreed to.

17. Governing law

These terms are governed by the laws of England and Wales. Any dispute will be heard exclusively in the courts of England and Wales.
