Terms of Use

1. Agreement

These Terms of Use (“Terms”) govern your access to and use of growapp.now and related services provided by AVENIX LTD (trading as GrowApp; “GrowApp”, “we”, “us”, or “our”) (collectively, the “Service”). AVENIX LTD is a company registered in the United Kingdom.

By accessing or using the Service, you agree to these Terms. Our Privacy Policy explains how we process personal data; it is a transparency notice and is not part of the contractual agreement itself.

The Service is intended only for individuals aged 18 or over. By using the Service, you confirm that you are at least 18 years old and have legal capacity to enter into these Terms under the laws of England and Wales.

2. Description of the Service

GrowApp provides subscribers with access to a curated research library focused on mobile app growth, including:

• Screenshots and screen recordings of mobile application interfaces
• Monthly change notes and analysis
• Growth hypotheses and digests
• Related editorial and reference materials

The Service is designed for inspiration, competitive research, product analysis, and understanding design and growth patterns. Materials relating to third-party applications (“Third-Party App Content”) are provided for informational and analytical purposes.

3. Accounts and access

Sign-in

Access to subscriber content requires a valid email address associated with an active subscription. We use passwordless magic links sent to your email to authenticate you. You must keep your email account secure and notify us if you suspect unauthorised access.

Accurate information

You agree to provide accurate contact information and to keep it up to date where relevant.

No account sharing

Your access is personal and non-transferable. You must not share sign-in links, session access, or credentials with others. We may suspend or terminate access if we reasonably believe account sharing or unauthorised access has occurred.

4. Who supplies your subscription

Your subscription for access to GrowApp is supplied by AVENIX LTD. Substack provides the checkout, payment-processing and subscription-management platform under Substack's applicable terms. AVENIX LTD remains responsible for providing access to the GrowApp Service and for handling issues relating to the availability or conformity of GrowApp content.

Card payments and chargebacks relating to the payment method may be processed through Substack and its payment partners. Issues about missing access, faulty digital content, or conformity of the GrowApp Service should be raised with us at [email protected]. Receipts or descriptors shown by Substack or its payment partners may identify Substack or a related billing descriptor; this does not change that AVENIX LTD supplies the GrowApp Service.

5. Fees, billing, and the right to cancel

Pricing, billing intervals, and included features are described on our Substack page and at checkout. By subscribing, you authorise Substack and its payment processors to charge applicable fees for the subscription supplied by AVENIX LTD.

Right to cancel (consumers)

If you are a consumer, you generally have a legal right to cancel a distance contract within 14 days, subject to the rules for digital content described below.

Where required by applicable consumer law, immediate access will begin only after you have expressly consented to supply beginning during the cancellation period and acknowledged that you will lose your right to cancel once supply begins. If the applicable checkout flow does not allow us to obtain the required consent and acknowledgement, your statutory cancellation rights will remain unaffected.

This does not affect your statutory rights where the digital content or Service is faulty, misdescribed, unavailable, or not supplied with reasonable care and skill under the Consumer Rights Act 2015 or other mandatory consumer law.

Cancellation of auto-renewal stops future billing according to Substack's cancellation controls; access typically continues until the end of the then-current billing period, subject to your statutory rights.

Nothing in these Terms excludes or limits any rights you have as a consumer under the laws of England and Wales or other mandatory consumer protections that cannot be waived under the laws of your country of residence.

6. Acceptable use

You may use the Service only for lawful purposes and in accordance with these Terms.

You may save or reproduce limited extracts of Service content solely for your own internal research and analysis, provided that you do not redistribute them or use them to create a substitute or competing library. You must not systematically copy, download, scrape, record, mirror, cache or archive substantial portions of the Service.

You also agree not to:

• Use bots, scrapers, crawlers, or other automated means to access the Service without our prior written consent
• Bypass authentication, rate limits, paywalls, or other access controls
• Reverse engineer, decompile, or attempt to derive source code from the Service
• Introduce malware or interfere with the operation, security, or integrity of the Service
• Resell, sublicense, redistribute, or commercially exploit Service content except as expressly permitted
• Use the Service to infringe intellectual property, privacy, or other rights of third parties
• Use Third-Party App Content to misrepresent affiliation with, endorsement by, or ownership of any third-party application
• Use Service content to train, fine-tune, evaluate, benchmark, or create datasets for an artificial intelligence or machine-learning model, or to create a searchable or generative substitute for the Service, without our prior written consent. This does not prohibit limited use of individual extracts in general-purpose AI tools for your internal analysis where the tool does not retain the content for model training and your use otherwise complies with these Terms
• Harass, abuse, or transmit unlawful, fraudulent, or harmful material through the Service

Violation of this section may result in suspension or termination and, where appropriate, legal action.

7. Intellectual property

Our rights

The Service — including its design, software, compilation, editorial content, branding, and arrangement of materials — is owned by AVENIX LTD or its licensors and protected by the Copyright, Designs and Patents Act 1988 and other applicable intellectual property laws.

We grant you a limited, non-exclusive, non-transferable licence to access and use the Service for your internal research, analysis, and inspiration, subject to these Terms and lasting for the period during which you are entitled to access the Service. No other rights are granted.

Third-Party App Content

Screenshots, recordings, and related materials depicting third-party applications remain the property of their respective owners (“IP Holders”). GrowApp does not claim ownership of underlying third-party app interfaces, trademarks, or copyrights.

• We are not affiliated with, endorsed by, or sponsored by IP Holders unless stated.
• Third-Party App Content is displayed for commentary, research, and educational analysis.
• Interfaces change frequently; we do not guarantee completeness, accuracy, or timeliness.

You are solely responsible for ensuring that any use of Third-Party App Content outside the Service complies with applicable law, including fair dealing exceptions under UK copyright law where available.

Intellectual property complaints

If you believe that content available through the Service infringes your intellectual property rights, please contact [email protected] and identify the relevant content, the rights concerned, your relationship to the rights holder, and the action you request. We may temporarily restrict access while reviewing a complaint.

Feedback

If you voluntarily provide feedback or suggestions, you grant us a worldwide, perpetual, royalty-free licence to use, reproduce, modify and incorporate that feedback into the Service. This does not transfer ownership of any confidential information or other materials that you provide and that do not constitute feedback.

8. Disclaimers

The Service and all content are provided on an “as is” and “as available” basis. To the fullest extent permitted by law, we disclaim all warranties, express or implied, including warranties of satisfactory quality, fitness for a particular purpose, non-infringement, and accuracy.

GrowApp is a research and reference tool. We do not guarantee that insights, hypotheses, or analyses will produce particular business outcomes. AI-assisted or human-written content may contain errors or omissions.

Nothing in these Terms excludes or limits liability for death or personal injury caused by negligence, fraud or fraudulent misrepresentation, or any other liability that cannot be excluded or limited under the laws of England and Wales.

9. Limitation of liability

Consumers

If you are a consumer, we are responsible for losses that are a foreseeable result of our breach of these Terms or failure to use reasonable care and skill. We are not responsible for losses that were not foreseeable or for business losses arising from consumer use. The liability cap below does not apply to refunds, price reductions, repeat performance, repair or other remedies that you are entitled to receive under mandatory consumer law, including the Consumer Rights Act 2015.

Business users

If you use the Service in the course of a business, subject to Section 8 and to the fullest extent permitted by applicable law, AVENIX LTD, its affiliates, and their directors, employees, agents, and licensors will not be liable for any indirect, incidental, special or consequential loss, or any loss of profits, revenue, data, goodwill, or business opportunities, arising from or related to your use of (or inability to use) the Service.

Subject to the same limitations, our total liability for any claim arising out of or relating to the Service or these Terms will not exceed the greater of (a) the amount you paid for the Service in the twelve (12) months before the event giving rise to the claim, or (b) one hundred pounds sterling (£100).

10. Indemnification

Consumers

If you are a consumer and your unlawful or deliberate misuse of the Service causes us to face a third-party claim, you may be responsible for the reasonable losses directly resulting from that misuse, to the extent permitted by law.

Business users

If you use the Service in the course of a business, you agree to indemnify AVENIX LTD against reasonable and documented third-party claims arising directly from your material breach of these Terms, unlawful use of the Service, or infringement of third-party rights.

11. Termination and discontinuation

You may stop using the Service at any time.

We may suspend or terminate your access immediately if you materially breach these Terms, engage in fraud or abuse, create a serious security risk, fail to pay amounts due, or if we are required to do so by law.

We may discontinue all or part of the Service for legitimate business reasons. Where reasonably possible, we will provide advance notice. If discontinuation prevents you from accessing prepaid subscription content before the end of your current billing period, we will provide continued access, an appropriate replacement, or a proportionate refund, unless the discontinuation is required immediately by law or a serious security risk. A proportionate refund will be calculated by reference to the unused part of your prepaid billing period.

Upon termination, your right to use the Service ends. Provisions that by their nature should survive (including intellectual property, disclaimers, limitation of liability, indemnification, and governing law) will survive.

12. Changes to the Service and Terms

We may modify features, content availability, or the Service interface at any time for operational, security, or product reasons.

We may also update these Terms. For minor changes (for example editorial corrections, technical clarifications, security updates, legally required updates, or changes that do not materially worsen your position), we may post the updated Terms on this page with a revised effective date.

For material changes that affect an active paid subscription — including price changes, reduced access, changes to the subscription period, new use restrictions, changes to the refund policy, or a material change to liability — we will, where reasonably practicable, give at least 14 days' advance notice (for example by email or a notice in the Service). Material changes will apply from the next renewal where possible. You may cancel before the change takes effect. Where reasonably possible, your current Terms will continue to apply until the end of your prepaid billing period.

If you do not agree to updated Terms that apply to you, you must stop using the Service and cancel any continuing subscription.

13. Governing law and disputes

These Terms and any dispute or claim arising out of or in connection with them (including non-contractual disputes or claims) are governed by the laws of England and Wales.

If you are a consumer, you may bring proceedings in the courts of the part of the United Kingdom or the EEA country in which you live, where applicable mandatory law gives you that right. If you are acting in the course of a business, the courts of England and Wales will have exclusive jurisdiction.

14. Miscellaneous

• Entire agreement — These Terms, together with any subscription terms presented at checkout, constitute the agreement between you and AVENIX LTD regarding the Service. Our Privacy Policy explains how we process personal data and is not part of that contractual entire agreement.
• Severability — If any provision is unenforceable, the remaining provisions remain in effect.
• No waiver — Failure to enforce a provision is not a waiver of that provision.
• Assignment — You may not assign these Terms without our consent. We may assign them in connection with a merger, acquisition, or sale of assets.
• Third-party rights — Except as expressly stated, a person who is not a party to these Terms has no right under the Contracts (Rights of Third Parties) Act 1999 to enforce any term of these Terms.
