Terms of use
Last updated 28 October 2026
The short version
- KnowLo is a free study aid for people aged 13 and over.
- It is for learning, not for treating real patients or giving medical advice.
- There are no payments, subscriptions or hidden fees.
About these terms
KnowLo (the website at knowloapp.com and the KnowLo app) is provided by Isak Gudbjornsson, an individual based in Iceland. By using KnowLo you agree to these terms. If you don't agree, please don't use it.
Who can use KnowLo
You must be 13 or older. If you are under 18, ask a parent or guardian to read these terms with you.
A study aid, not medical advice
KnowLo is for education. It does not replace professional training, clinical supervision, official guidelines or medical advice. Don't use it to diagnose or treat real people. The content is checked carefully, but it may contain mistakes or be out of date, and it does not cover everything. If you spot an error, email isak@knowloapp.com.
Price
KnowLo is free. There are no payments, subscriptions or hidden fees. If paid features are ever added, the price will be shown clearly before you pay, and these terms will be updated first.
Refunds
Nothing is sold at the moment, so there is nothing to refund. If paid features are added later, you will keep every right you have under consumer law, including the right to withdraw from an online purchase within 14 days where that applies. Purchases made through Apple's App Store are refunded through Apple.
Your account
The app currently runs on claude.ai, so you need a Claude account to use it. Anthropic's terms apply to that account. You are responsible for keeping your account secure.
Fair use
Please don't:
- Try to break, overload or get around how KnowLo works.
- Copy its question content to publish or sell elsewhere.
- Use the AI patient to create harmful or abusive content.
Content and licences
- KnowLo's text, questions and design are © 2026 Isak Gudbjornsson.
- The 3D anatomy renders come from BodyParts3D, © The Database Center for Life Science, licensed CC BY-SA 2.1 JP. They were cropped or resized for KnowLo, and those versions are shared under the same licence.
- Other pictures come from Wikimedia Commons under the licences listed in the app's Image credits. Gray's Anatomy plates (1918) are in the public domain.
- The Sora and Lexend fonts are used under the SIL Open Font License 1.1.
- The AI patient's replies are generated by Claude, an AI model by Anthropic.
Changes and availability
KnowLo may change, pause or stop. Advance notice is given where possible. If these terms change, the date at the top changes, and important changes are announced in the app.
Liability
KnowLo is provided as it is. As far as the law allows, Isak Gudbjornsson is not responsible for indirect losses, or for decisions made based on its content. This does not limit liability for harm caused on purpose or through gross negligence, and nothing in these terms limits rights you have under mandatory consumer law.
Law
These terms are governed by Icelandic law. If you are a consumer living elsewhere in the EEA, you also keep the protections of your own country's law.
