Terms of Use
By using Kleos you agree to these terms.
Subscriptions and free trials
Kleos Premium is offered weekly ($6.99), monthly ($12.99) or yearly ($59.99), each with a 7-day free trial. Subscriptions renew automatically until cancelled. You can cancel any time in your App Store or Google Play settings; if you cancel during the trial you will not be charged. Refunds are handled by Apple or Google under their policies.
AI Mentor
Mentor responses are generated by AI. They are not the words of the historical figure, not a historical source, and not professional advice (medical, legal, financial or otherwise).
Content
We work hard to verify quotes and historical facts, but we cannot guarantee that everything is error-free. Portraits and artworks are public domain or used under free licences and credited to Wikimedia Commons. The Kleos name, logo, design and original text belong to us.
Acceptable use
Do not misuse the service, try to break or overload it, or use the Mentor to create harmful content.
Liability
Kleos is provided “as is”. To the extent the law allows, we are not liable for indirect or consequential losses arising from your use of the service.
