Terms of Service

These Terms of Service ("Terms") are an agreement between you and Sean Prentice, a sole trader (ABN 15 662 058 576) ("Cairn", "we", "us", or "our"), and govern your use of the Cairn mobile application and related services (the "Service"). Please read them carefully. By creating an account or using Cairn, you agree to these Terms. If you do not agree, do not use the Service.

1. Eligibility

You must be at least 16 years old to use Cairn. By using the Service, you confirm that you meet this requirement.

2. Your account

  • An account is required to use Cairn. You agree to provide accurate information and to keep your login details secure.
  • You are responsible for activity that occurs under your account.
  • Notify us promptly at support@get-cairn.app if you believe your account has been accessed without authorisation.

3. The Service

Cairn is a hiking memory and journal app. It lets you record hikes, add photos and notes, view maps and statistics, generate written recaps, and revisit your past hikes. We may add, change, or remove features over time.

Some features are free. Others require a paid Cairn+ subscription, including AI hike narratives, the Memory tab, the photo map, year in review, multi-device cloud sync, shareable Trip Book links, and a discount on physical Trip Books.

4. Safety and reliance (please read)

Cairn is a memory and journaling tool. It is not a navigation, mapping, emergency, or safety device, and must not be relied on for any of those purposes.

  • Do not rely on Cairn for navigation, route-finding, location accuracy, or to get yourself out of difficulty. GPS and background detection can be inaccurate, delayed, or unavailable, and the app may not function in remote areas or without signal or battery.
  • You are solely responsible for your own safety, planning, equipment, fitness, and decisions when hiking or undertaking any outdoor activity.
  • Always carry appropriate navigation and safety equipment, check conditions, tell someone your plans, and follow the guidance of local authorities and land managers.
  • Trailhead detection, park recognition, and similar features are provided for convenience only and may be incomplete or wrong.

You use the Service and undertake any activity recorded with it at your own risk.

5. Subscriptions, billing, and physical products

5.1 Cairn+ subscriptions

  • Cairn+ is offered as an auto-renewing subscription. Pricing is shown in the app (for example, AUD $7.99 per month, with prices varying by region and subject to change).
  • Payment is charged to your Apple ID account at confirmation of purchase. Subscriptions renew automatically unless cancelled at least 24 hours before the end of the current period. Your account is charged for renewal within 24 hours before the period ends.
  • You manage and cancel subscriptions through your Apple ID account settings, not within Cairn. Deleting the app does not cancel a subscription.
  • Subscriptions are managed using RevenueCat and processed by Apple.

5.2 Refunds

Purchases and subscriptions made through the App Store are subject to Apple's refund policies. As the seller of record for in-app purchases, Apple handles billing and refunds. We are generally unable to issue refunds directly for App Store transactions. Nothing in these Terms limits any rights you have under the Australian Consumer Law or other mandatory consumer protection laws.

5.3 Physical products

  • Cairn may offer physical products, such as a printed Trip Book, as separate one-time purchases.
  • Physical products are manufactured and shipped by a third-party print provider (Lulu). Production and delivery times, shipping, and availability depend on that provider.
  • You are responsible for providing an accurate shipping address. We are not responsible for delays or non-delivery caused by incorrect address details.
  • Because physical products are made to order and personalised to your content, returns and refunds are limited to faulty or damaged items, except where mandatory consumer law provides otherwise.

6. Your content

  • You own your content. You keep all rights to the hikes, photos, notes, and other content you create or add to Cairn ("Your Content").
  • Licence to operate the Service. You grant us a limited, non-exclusive, worldwide, royalty-free licence to host, store, copy, process, transmit, and display Your Content solely as needed to provide and improve the Service for you. This includes processing hike details through our AI provider to generate narratives, generating documents and physical products you request, and backing up and synchronising your data. This licence ends when you delete the relevant content or your account, subject to reasonable backup retention.
  • Responsibility. You are responsible for Your Content and confirm you have the rights to it, and that it does not infringe the rights of others or break any law.

7. AI-generated content

Cairn uses artificial intelligence to generate written narratives and recaps. These are produced automatically, may be inaccurate or incomplete, and are provided as a creative recap rather than a factual record. You should not rely on AI-generated text as accurate information about a location, route, conditions, or anything else.

8. Acceptable use

You agree not to:

  • Use the Service for any unlawful purpose or in breach of these Terms.
  • Upload content that is unlawful, infringing, harmful, or that you do not have the right to upload.
  • Attempt to access, interfere with, disrupt, reverse engineer, or compromise the Service or its security, except to the extent this restriction is prohibited by law.
  • Use the Service to build or train a competing product, or scrape or extract data from it at scale.
  • Misuse sharing features, or share another person's information without their consent.

We may suspend or terminate access for breach of these Terms.

9. Sharing features

Cairn lets you create shareable web links to your Trip Books. Anyone with a share link can view the shared content without an account. You are responsible for deciding who to share links with. You can revoke a share link from within the app.

10. Our intellectual property

The Service, including the Cairn name, logo, software, design, and content we provide (but excluding Your Content), is owned by us or our licensors and protected by intellectual property laws. We grant you a limited, personal, non-transferable, non-exclusive, revocable licence to use the app for its intended purpose. You may not copy, modify, distribute, or create derivative works from the Service except as allowed by law.

11. Third-party services

The Service relies on third-party providers (including Apple, Supabase, Anthropic, RevenueCat, Mapbox, Lulu, PostHog, and others). Your use of certain features may also be subject to those providers' terms. We are not responsible for third-party services, and their availability may affect the Service.

12. Disclaimers

To the maximum extent permitted by law, the Service is provided "as is" and "as available", without warranties of any kind, whether express or implied, including fitness for a particular purpose, accuracy, reliability, or uninterrupted availability. We do not warrant that the Service will be error-free, that data will never be lost, or that location features will be accurate.

Nothing in these Terms excludes, restricts, or modifies any consumer guarantee, right, or remedy under the Australian Consumer Law or other applicable law that cannot lawfully be excluded. Where our liability cannot be excluded but can be limited, our liability is limited to the maximum extent permitted by law.

13. Limitation of liability

To the maximum extent permitted by law, and subject to section 12:

  • We are not liable for any indirect, incidental, special, consequential, or punitive damages, or for loss of data, profits, or goodwill, arising from your use of or inability to use the Service.
  • We are not liable for any injury, loss, or damage arising from your hiking or outdoor activities, or from reliance on the Service for navigation or safety, which it is not designed for.
  • Our total aggregate liability for any claim relating to the Service is limited to the greater of the amount you paid us for the Service in the 12 months before the claim, or AUD $100.

14. Indemnity

You agree to indemnify and hold us harmless from claims, losses, and expenses (including reasonable legal costs) arising from your breach of these Terms, your misuse of the Service, or Your Content, to the extent permitted by law.

15. Termination

You may stop using the Service and delete your account at any time from within the app. We may suspend or terminate your access if you breach these Terms or if we discontinue the Service. On termination, your right to use the Service ends. Sections that by their nature should survive termination (including content licences for backups, disclaimers, limitations of liability, and indemnity) will survive.

16. Changes to these Terms

We may update these Terms from time to time. If we make material changes, we will notify you through the app or by other reasonable means and update the "Last updated" date. Continued use of the Service after changes take effect means you accept the updated Terms.

17. Governing law

These Terms are governed by the laws of New South Wales, Australia, and you submit to the non-exclusive jurisdiction of the courts of that state. This does not deprive you of the protection of mandatory consumer laws in your country of residence.

18. Contact

Questions about these Terms can be sent to support@get-cairn.app.

Schedule A: Apple App Store additional terms

  • Apple is not responsible for addressing any claims by you or a third party relating to the app, including product liability, legal or regulatory non-compliance, or consumer protection claims.
  • Apple is not responsible for the investigation, defence, settlement, or discharge of any third-party intellectual property infringement claim relating to the app.
  • You represent that you are not located in a country subject to a relevant government embargo, and are not on any relevant restricted-parties list.
