Terms of Service

Last updated: 15 May 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 hello@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, and others. When you connect one:

• You authorise us to access your data on that service on your behalf, limited to what you choose during the connection flow.
• We store the access tokens encrypted and use them only to fetch the data you’ve asked us to surface in Growth Method.
• 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 features

Growth Method uses AI (currently OpenAI and Anthropic models) to score ideas, summarise experiments, suggest next steps, and power in-app chat. 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.

8. Subscriptions and billing

• Billing. Subscriptions are billed in advance through our payment processor (Stripe). You can choose to pay monthly or annually.
• 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 hello@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 hello@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.

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,
• 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:

• We’re not liable for indirect, incidental, consequential, special, or punitive damages, including lost profits, lost revenue, lost data, or business interruption, even if we’ve been told they’re possible.
• Our total liability to you for any claim relating to the Service is capped at the amount you paid us in the 12 months before the event giving rise to the claim, or £100, whichever is greater.

These limits don’t apply to liability that can’t be limited under English law (e.g. 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,
• 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 occasionally. When we do:

• Material changes: we’ll email account owners at least 30 days before the change takes effect.
• Minor changes (typos, clarifications, new sub-processors): we’ll update the page and the “Last updated” date.

Your continued use of the Service after a change takes effect means you accept the new terms. If you don’t accept, cancel your account before the change date.

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.
