Rosetta Lens Terms of Use

Last updated: 11 October 2026

These Terms of Use (the "Terms") apply to the Rosetta Lens mobile app for iOS and Android (the "App") and the related services we provide, including cloud reading (together, the "Service"). The App is provided by [LEGAL ENTITY NAME] (ABN [ABN]), trading as ethosec, of Queensland, Australia ("we", "us", "our").

By downloading, installing or using the App, you agree to these Terms. If you do not agree, please do not use the App.

Summary

• The App helps you read ancient inscriptions from your photos. Readings are produced by machine-learning models and can be wrong. Treat them as a helpful guide, not as expert or scholarly authentication.
• Purchases, subscriptions and refunds are handled by Apple (App Store) or Google (Google Play). Manage or cancel subscriptions in your store account.
• Nothing in these Terms limits your rights under the Australian Consumer Law or other consumer laws that apply to you.
• Our Privacy Policy explains how we handle your information.

1. Who these Terms apply to

You must be at least 13 years old (or the minimum age in your country) to use the App. If you are under 18, please make sure a parent or guardian has read and agreed to these Terms, and that they approve any purchases.

2. Apple App Store users

If you obtained the App from the Apple App Store:

• Your use of the App is governed by Apple's Licensed Application End User License Agreement (the "Apple Standard EULA"): https://www.apple.com/legal/internet-services/itunes/dev/stdeula/. These Terms add to the Apple Standard EULA. If they conflict, the Apple Standard EULA applies to the extent of the conflict, except that our obligations under the Australian Consumer Law are not reduced.
• These Terms are between you and us, not Apple. Apple is not responsible for the App or its content.
• Apple has no obligation to provide maintenance or support for the App.
• If the App fails to conform to any applicable warranty, you may notify Apple, and Apple may refund the purchase price (if any) for the App. To the maximum extent permitted by law, Apple has no other warranty obligation for the App. Any other claims, losses, liabilities, damages, costs or expenses due to a failure to conform to a warranty are our responsibility, subject to these Terms and the law.
• We, not Apple, are responsible for addressing any claims by you or a third party relating to the App or your possession or use of it, including product liability claims, claims that the App fails to meet legal or regulatory requirements, and claims under consumer protection, privacy or similar laws.
• If a third party claims that the App or your possession or use of it infringes their intellectual property rights, we, not Apple, are responsible for investigating, defending, settling and discharging that claim.
• You represent that you are not located in a country subject to a US Government embargo or designated as a "terrorist supporting" country, and that you are not on any US Government list of prohibited or restricted parties.
• Apple and its subsidiaries are third-party beneficiaries of these Terms and, once you accept them, Apple may enforce them against you as a third-party beneficiary.

3. Google Play users

If you obtained the App from Google Play, your purchase and download are also subject to the Google Play Terms of Service: https://play.google.com/about/play-terms/. Google is not a party to these Terms and is not responsible for the App.

4. Your licence to use the App

We grant you a personal, non-exclusive, non-transferable, revocable licence to install and use the App on devices you own or control, for your own non-commercial purposes, in line with these Terms and the rules of the store you obtained it from.

You must not copy, modify, sell, rent, sublicense or distribute the App; reverse engineer, decompile or try to extract its source code, models or data (except where the law allows this despite this restriction); or remove any notices.

5. Plans, subscriptions, packs and passes

The App offers a Free plan and paid options, which may include the [MIDDLE PLAN NAME] and Pro subscription plans, reading packs and trip passes. What each option includes, its price and its reading allowance are shown in the App before you buy.

• Payments: all purchases are made through, and charged by, Apple or Google, under their terms. We do not receive or store your payment card details.
• Subscriptions renew automatically at the end of each period unless you cancel at least 24 hours before the renewal date. You can manage or cancel a subscription in your App Store or Google Play account settings (see Support). Deleting the App does not cancel a subscription.
• Monthly reading allowances reset each month. Unused readings from a monthly allowance do not carry over.
• Reading packs add a set number of readings that are used after your plan's monthly allowance. Packs expire 12 months after purchase.
• Trip passes add readings for a limited period (currently 7 days from activation) and do not renew. Buying another pass while one is active extends it.
• Failed readings are not charged. If a cloud reading fails because of a problem on our side or with our provider, it is not counted against your allowance.
• Refunds are handled by Apple or Google under their refund processes. This does not limit your rights under the Australian Consumer Law (see section 12).
• Restoring purchases: use the App's Restore Purchases option on a device signed in to the same Apple ID or Google account. Because the App has no accounts, your balances are linked to your store purchase records.
• Price changes: we may change prices for future billing periods or new purchases. Apple or Google will tell you about subscription price changes as their rules require.

6. Cloud reading and fair use

Cloud reading is available only on the Pro plan. It is never used on the Free or [MIDDLE PLAN NAME] plans, which read photos on your device. It is provided only when you request it for a particular photo, as described in our Privacy Policy. To keep the Service reliable and affordable, we apply reading allowances and technical limits (such as rate limits), and we may temporarily restrict use that looks automated, abusive or likely to harm the Service or other users.

The Service relies on third-party providers (see section 11) and on internet connectivity. We aim to keep it available, but we do not promise that it will be uninterrupted or error-free.

7. Accuracy of readings

Ancient inscriptions are often damaged, partial, ambiguous or unfamiliar, and the App's readings, translations, transliterations, dates and explanations are generated by machine-learning and artificial-intelligence models, including third-party models. They may be incomplete or wrong, and different readings of the same photo may differ.

• Readings are for general interest and education only. They are not expert, scholarly, archaeological or legal opinions, and they do not authenticate, date or value any object.
• Do not rely on a reading for academic publication, purchase or sale of artefacts, legal or customs matters, or any decision where an error could cause loss, without checking it with a qualified expert.
• A confidence score in a reading is the model's own estimate, not a guarantee.

This section does not exclude any consumer guarantee that cannot be excluded (see section 12).

8. Acceptable use

You must not:

• use the App in a way that breaks the law, including heritage, cultural property, trespass and site-access laws, or the rules of a museum or site;
• damage, touch or disturb inscriptions, monuments or artefacts to take a photo;
• photograph people without the consent the law requires, or send photos of other people for cloud reading;
• upload content that is unlawful, harmful, or that infringes someone else's rights;
• attempt to bypass reading allowances, rate limits, purchase checks or security measures, or access the Service by automated means (for example scripts or bots) or through anything other than the App;
• interfere with, overload or attack the Service, or try to obtain our API keys, models or other users' information;
• resell, sublicense or commercially exploit the Service or its outputs at scale without our written permission.

9. Your photos and content

You keep ownership of your photos and any content you create. When you request a cloud reading, you give us a limited, non-exclusive licence to process that photo and the related details only for the purpose of producing your reading, as described in our Privacy Policy. We do not store your photos and we do not use them to train our own models.

You are responsible for having the right to photograph and submit the images you use with the App.

10. Our intellectual property

The App, its design, software, models (other than third-party components), text and branding are owned by us or our licensors and are protected by intellectual property laws. Third-party components and datasets are used under their own licences (see Licences). Except for the licence in section 4, these Terms do not give you any rights in our intellectual property.

You may use the readings the App produces for your own personal, non-commercial purposes. Readings of public-domain ancient texts are not owned by us, but the App's software and presentation are.

11. Third-party services and data

The Service uses third-party providers, including Cloudflare (hosting and security), xAI (the Grok API used for cloud readings), and Apple and Google (distribution and payments). Their services are governed by their own terms, and we are not responsible for their acts or omissions except as required by law. The App also uses third-party datasets and open-source software, credited on our Licences page.

12. Australian Consumer Law

Our goods and services come with guarantees that cannot be excluded under the Australian Consumer Law (Schedule 2 to the Competition and Consumer Act 2010 (Cth)). For major failures with the service, you are entitled to cancel your service contract with us and to a refund for the unused portion, or to compensation for its reduced value. You are also entitled to choose a refund or replacement for major failures with goods. If a failure with the goods or a service does not amount to a major failure, you are entitled to have the failure rectified in a reasonable time. If this is not done, you are entitled to a refund for the goods and to cancel the contract for the service and obtain a refund of any unused portion. You are also entitled to be compensated for any other reasonably foreseeable loss or damage from a failure in the goods or service.

Nothing in these Terms excludes, restricts or modifies any right or remedy, or any guarantee, warranty or other term or condition, implied or imposed by the Australian Consumer Law or any other law that cannot lawfully be excluded or limited ("Non-excludable Rights"). If you are a consumer in another country, you may also have rights under your local law that these Terms cannot override.

13. Limitation of liability

Subject to your Non-excludable Rights:

• the App and Service are provided "as is" and "as available", and we exclude all warranties, guarantees and conditions that are not expressly set out in these Terms;
• where our liability for a failure to comply with a consumer guarantee can lawfully be limited, it is limited, at our option, to supplying the services again or paying the cost of having them supplied again (for services), or replacing or repairing the goods or paying for that (for goods);
• we are not liable for any indirect or consequential loss, or for loss of profits, revenue, data, opportunity or goodwill, arising from your use of the App or reliance on a reading; and
• to the extent permitted by law, our total liability to you for all claims relating to the App and Service is limited to the amount you paid for the App or in-app purchases in the 12 months before the claim arose.

Nothing in these Terms limits liability for death or personal injury caused by negligence, for fraud, or for anything else that cannot be limited by law.

14. Changes, suspension and termination

We may update the App, add or remove features, or change these Terms, for example to reflect changes to the Service or the law. If a change is significant, we will tell you in the App or on this page before it takes effect. If you keep using the App after a change takes effect, the updated Terms apply. If you do not agree, you can stop using the App and cancel any subscription; you may also have rights under section 12.

We may suspend or end your access to the Service if you seriously or repeatedly breach these Terms, or if we need to for legal or security reasons. If we stop providing the Service entirely, we will give reasonable notice where we can, and remedies for any prepaid, unused paid features will be handled in line with the store's refund processes and your Non-excludable Rights.

15. Governing law

These Terms are governed by the laws of Queensland, Australia. You and we submit to the non-exclusive jurisdiction of the courts of Queensland and the Commonwealth of Australia. If you are a consumer living in another country, you may also be able to bring proceedings in your local courts and rely on mandatory local consumer laws.

If any part of these Terms is invalid or unenforceable, the rest remains in effect. A failure to enforce any part is not a waiver.
