Effective from 4/11/2026
These terms cover your use of the Lumen Anatomy website, account and desktop application. Lumen Anatomy is operated by Lachlan Theodore (ABN 46 840 825 499). In these terms, “we” means that operator. If you buy or manage a subscription for an organisation, you confirm you have authority to act for it.
Paddle is the authorised reseller and merchant of record for purchases made through our checkout. Its Buyer Terms govern the purchase and payment transaction. These terms govern your use of Lumen Anatomy and your software licence. Our Refund Policy explains how to get help with a refund.
Lumen Anatomy shows generalised 3D anatomy for teaching, study and explaining anatomy to patients. It is not intended for use as a medical device. Its illustrations and injury examples may simplify anatomy and do not represent any individual patient. Do not use Lumen to diagnose, assess, monitor or treat a person, interpret medical images, or make clinical decisions. Use your own professional judgement and appropriate clinical sources.
Lumen is not a patient record system. Keep patient names, images, scans, case notes and other identifiable health information out of the app, saved views, screenshots shared with us, and support messages.
Before you pay, checkout shows your selected plan, billing interval, amount due, any introductory discount, and the price that applies after the offer. The checkout shows the currency and applicable tax. By completing checkout you authorise Paddle to charge your chosen payment method for the first payment and future renewals. Monthly subscriptions renew monthly and annual subscriptions renew annually until cancelled. An introductory offer applies only for the period displayed at checkout.
You can cancel future renewals from Account by opening Manage subscription, or use the subscription link in your Paddle receipt or Paddle buyer support. Cancel before the next charge to prevent renewal. Ordinary cancellation takes effect at the end of the current paid period. Cancelling does not itself request a refund.
We will give advance notice of a price increase affecting your subscription and seek your consent where required. You can cancel before it takes effect. A failed payment may be retried. If the subscription ends or payment remains unresolved, the app may stop renewing your licence and lock when its current key expires.
While your subscription entitles you to access, you may install and use Lumen under the plan you bought. Each licence is for one named practitioner or one treatment room, and works on one computer at a time. You may move a licence to a new computer, up to twice in any 30 days, by removing the old computer in Lumen (Settings › Account) or on your account page. You may not share a licence between computers or people. A computer you haven’t used for 60 days frees its place automatically. The named user may display Lumen to patients or students for education. A clinic buys one licence for each computer that will run Lumen, and is responsible for the licences it names. Clinic owners can assign or reassign licences through their account. The clinic plan starts at three computers. Student pricing requires eligibility verification. If you cannot verify through your university email, contact Support to ask about manual review.
Initial activation requires an internet connection. You can use the app offline while its licence key is valid. The app needs to reconnect periodically to renew a subscription key. If a computer needs to be replaced, remove it in your account or in the app, then activate the replacement; this counts as one of the two changes allowed in a rolling 30-day period. Contact support if a device failure prevents you from moving your licence.
Keep sign-in links and licence codes private. You may not share a licence or licence code with an unassigned person, resell access, redistribute the installer or proprietary software, or bypass access controls for the proprietary software. These limits are subject to your rights under applicable law and do not limit any rights you have under a separate licence for third-party material.
The software, branding and other proprietary material are owned by us or our licensors. Your subscription gives you a right to use the app under these terms. It does not transfer ownership. Separately licensed anatomy assets, fonts and software components remain under their own licences. The app licence and its access restrictions do not take away the rights those licences grant. See Attributions for sources and licence terms.
We may release updates to fix issues, improve security or change features. We will give reasonable notice of changes that materially reduce a paid service or affect your rights, where practicable. Your statutory rights and any remedies that apply to your purchase continue to apply.
Access may end when a subscription ends, is refunded, or a clinic removes your licence. We may suspend access where reasonably necessary to address fraud, a security risk or a serious breach of these terms. Where practicable, we will explain the reason and give you a reasonable chance to resolve it. If immediate action is necessary, we will explain the reason afterwards where it is lawful and safe to do so. If you think access was restricted in error, contact us.
Nothing in these terms excludes, restricts or modifies any right, guarantee or remedy that cannot lawfully be excluded, including under the Australian Consumer Law. The educational limits above describe the app’s intended use. They do not remove your rights if the app fails to meet a consumer guarantee or differs materially from what was promised.
For questions about the app, accessibility, your licence or these terms, contact [email protected]. See the Privacy Policy for how we handle personal information.
This policy explains how [Legal operator name] (ABN 46 840 825 499), operating Lumen Anatomy, handles personal information when you use our website, desktop app, subscriptions or support. For privacy enquiries, email [email protected].
You can browse public pages without signing in. If you choose not to provide information needed for a particular feature, we may be unable to activate your licence, verify a student discount, manage your account or respond to a support request.
The desktop app stores local profiles, preferences, favourites and saved anatomy views on your computer. It does not sync these to your website account. The models are generic educational assets. The app does not connect to patient records or upload your saved anatomy views as part of normal use. Licence activation, licence renewal and update checks use the internet. If you choose to email a screenshot, session export or diagnostic file to support, we receive what you send. Check it first and remove any identifying or health information.
The account uses essential cookies to keep you signed in and show your sign-in status. You can sign out or clear these cookies in your browser. Blocking them can prevent account features from working. Paddle may use its own cookies or similar technologies for checkout, billing security and fraud prevention. See Paddle’s Privacy Notice.
Service emails include sign-in links, licence details, receipts, payment or renewal notices, and support replies. These are sent as needed to provide your account or subscription. Marketing is optional and sent only where you have opted in. You can unsubscribe from marketing using the link in the message or by contacting us. You can also update your preferences in Account.
These providers may process information outside Australia. This includes the United States for email delivery and cloud services and may include the United Kingdom for Paddle billing. The countries involved can depend on the provider, the service and the Paddle entity handling a transaction. See the provider notices for further details. We take reasonable steps to protect personal information handled by overseas service providers in accordance with applicable law.
We use encrypted web connections, time-limited sign-in links and access controls to help protect personal information. We keep information as needed to run your account and subscription, meet legal and accounting obligations, prevent abuse and resolve disputes. Sign-in links expire after 15 minutes and account cookies are issued for up to 30 days. We remove or de-identify personal information when it is no longer needed, subject to lawful retention requirements.
You can request account deletion from Account or contact us. Deleting the account cancels subscriptions it owns and removes or de-identifies associated account information where appropriate. Some transaction, legal or security records may need to be retained. Paddle may retain its own billing records. Deleting your website account does not erase the data on your own computer. For help removing local app data, contact support.
Email [email protected] to ask what personal information we hold about you, request a correction, or raise a privacy complaint. Tell us what happened and what outcome you are seeking. We may need to verify your identity. We will review your request and aim to respond within 30 days. If a privacy complaint is unresolved, and it falls within the Office of the Australian Information Commissioner’s jurisdiction, you can contact the OAIC.
We will update the effective date when we revise this policy and provide additional notice of material changes where appropriate.
If you cannot download or activate Lumen, it does not work as described, or something is wrong with your purchase, contact us. We can help with installation or licensing and work with Paddle on the billing side.
You may be entitled to a repair, replacement, refund, cancellation or another remedy under the Australian Consumer Law, depending on what went wrong. Where the law lets you choose a remedy, that choice is yours. Your rights may also apply to a clinic purchase. Nothing in this policy or the Paddle process limits those rights. A consumer guarantee claim is not subject to a voluntary change-of-mind deadline. ACCC guidance on consumer remedies
If Lumen isn’t right for you, request a refund within 30 calendar days of your first paid subscription charge. We’ll refund the full amount you paid for that first charge. Email [email protected] with your purchase email and Paddle receipt or transaction reference. We’ll help arrange the refund through Paddle and confirm how to stop future renewal charges.
This voluntary guarantee covers the first payment only. It does not limit any rights or remedies you have under the Australian Consumer Law or other applicable law. Other change-of-mind requests are handled under Paddle’s Refund Policy.
To stop future payments, use Manage subscription in Account, the link in your Paddle receipt, or Paddle buyer support. Cancellation before renewal prevents the next scheduled charge. It does not itself refund an earlier charge. If you request a refund and want to end your subscription, check that future renewals are cancelled as well.
When a refund ends your licence entitlement, we stop issuing or renewing keys for that subscription. An offline installation may continue to open until its current key expires.
Lumen Anatomy’s anatomical model collection is based on Z-Anatomy, the libre 3D atlas of anatomy.
