Terms of use

Effective 5 October 2026. These terms apply to access of Halcyon editorial pages from Indonesia and elsewhere.

They cover articles, photographs, illustrations, navigation, contact features, and any downloadable editorial material made available through the public site. If a page contains a specific notice, that notice should be read together with these terms. Nothing here removes a mandatory consumer right or prevents a reader from using a lawful remedy available in Indonesia.

Questions about interpretation, accessibility, or a suspected breach should first be sent to Halcyon at Jalan Mawar No. 45, Kebayoran Baru, Jakarta Selatan, Jakarta 12160, Indonesia, or +62 857 2341 9876. We normally acknowledge a written concern within 10 business days and explain the next review step if source checking or technical investigation is needed. Material revisions are recorded by date; this version is effective 5 October 2026. If a provision is found unenforceable, the remaining terms continue to operate to the extent permitted by Indonesian law.

1. Use of the publication

Halcyon provides general educational material about athletic physiology and endurance. It is not medical diagnosis, treatment, coaching supervision, or an emergency service. Readers remain responsible for considering their own circumstances and seeking a qualified professional where symptoms, medication, or medical history make that appropriate. Content may be updated as research and editorial review develop.

A sensible use is to read an article as background for a conversation with a qualified professional or as a prompt for a personal training log. A reader should not treat a general example as an individualized instruction, especially where a medical history, medication, injury, or unusual symptom is involved. The site is not continuously monitored for urgent requests, and contact messages are answered during ordinary editorial review rather than emergency response.

You may read, link to, and quote brief passages with attribution. You may not scrape, republish the publication as your own, interfere with site security, or use the material to create misleading health claims. We aim to keep links and explanations accurate, but cannot promise uninterrupted availability or a particular outcome from applying an idea. Indonesian law governs these terms, subject to mandatory consumer protections.

• Attribution should name Halcyon and link to the original page where practical.
• Quotations must not be edited in a way that changes their meaning or suggests endorsement.
• Automated extraction, bulk copying, probing, or attempts to bypass access controls are not permitted.
• Readers remain responsible for checking whether linked information is current before relying on it.

Halcyon owns or licenses the site's text, design, photographs, marks, and arrangement unless a credit says otherwise. A limited, non-exclusive permission to read and make brief attributed quotations does not transfer ownership. Permission for republication can be requested from the editorial desk and may depend on the requested excerpt, context, and rights held by a third party.

Contact forms must be used honestly and lawfully. Do not submit malicious code, another person's confidential information, abusive material, or a message intended to disrupt service. We may retain correspondence for up to 24 months after the last exchange and technical security records for up to 90 days, as described in the privacy policy.

Third-party links, hosting, analytics, email, and embedded services may have separate terms. Halcyon is not responsible for changes made by an external operator, but we may remove a link when it becomes inaccurate, unsafe, or inconsistent with editorial standards. A temporary outage, maintenance window, or technical error does not create a promise of continuous availability.

Questions about these terms should be sent to Jalan Mawar No. 45, Kebayoran Baru, Jakarta Selatan, Jakarta 12160, Indonesia, or +62 857 2341 9876. We aim to acknowledge a substantive enquiry within 10 business days and respond within 30 days where the matter can be resolved from the information supplied.
