Terms & Conditions

In effect from October 20, 2026

01:00 — Agreement at a glance

This summary is for convenience only; the full text that follows controls.

• The Space shares general body-clock information. It is not medical care.
• The planner and clock run on your device and give estimates, not prescriptions.
• Sunrise Notes is free and you can stop it any time.
• You may read and share links, but not copy or scrape our material.
• Disputes go to individual arbitration with ADR Services, Inc., unless you opt out within 30 days.
• Our total liability is limited to $35.

02:00 — Parties and acceptance

These Terms & Conditions are an agreement between you (a Riser) and the HerSpace Keepers, meaning the independent operator that publishes circadianherspace.com under the trade name CircadianHerSpace and those who write and maintain it. They apply to the website, the live clock, the personal planner and the Sunrise Notes newsletter (together, the Space). Using the Space or subscribing to Sunrise Notes means you accept them, along with our Privacy Policy.

03:00 — Eligibility

You must be 18 or older to use the Space or subscribe. The Space is designed for readers in the United States.

04:00 — General wellness information

The Space explains, in everyday language, how daylight, meal timing, daytime activity and evening routines relate to the body clock, particularly during perimenopause and after. It is educational. The HerSpace Keepers are not physicians, sleep specialists or dietitians, and no clinician–patient relationship is created by reading the Space or writing to us.

This is general wellness information, not medical advice. If you have ongoing sleep problems, hot flashes that disrupt your sleep, symptoms of a sleep disorder such as loud snoring or pauses in breathing, or if you work night shifts, please speak with your doctor before changing your routine.

Take particular care, and seek professional advice first, if any of the following applies to you:

• you have diabetes, low blood sugar or an eating disorder, or take medication with food requirements, before changing meal timing or eating windows;
• you have an eye condition, migraines triggered by light, or a light-sensitive skin or medical condition, before increasing bright-light or sun exposure;
• you use or are considering hormone therapy, sleep medication or supplements such as melatonin;
• you have heart, joint or balance problems, before starting new daytime movement; or
• you feel persistently low, anxious or unable to sleep for weeks at a time.

05:00 — The clock and the planner

The live sky reflects your device clock and may be inaccurate if your device time or time zone is wrong. The planner applies general rules of thumb to the wake time and sleep goal you enter. Its windows are suggestions only; bodies, schedules and health differ, and you are responsible for deciding what suits you. Because the tools run in your browser, we cannot see, save or recover your entries.

06:00 — Sunrise Notes

Sunrise Notes is a free Monday email. Its content, format and timing may change, and it may be paused or ended. Recipes are offered for general interest; check every ingredient against your own allergies, intolerances and dietary needs, and follow safe food-handling practice. Each issue identifies the sender and includes an unsubscribe link.

07:00 — Respecting our work

The writing, planner logic, illustrations, sky animation, recipes and the CircadianHerSpace name belong to or are licensed to the HerSpace Keepers. You may read the Space, keep a copy of a page or a Sunrise Notes issue for personal reference and share links. Without written permission you may not reproduce substantial parts of the Space, reuse recipes or illustrations commercially, frame the site, harvest it with automated tools, or include its content in any AI training, retrieval or fine-tuning collection.

Ideas you send us may be used without obligation to you. Notices of claimed copyright infringement can be sent to support@circadianherspace.com and should identify the work, the location of the material and your contact details.

08:00 — Acceptable conduct

Do not attempt to disrupt, overload, reverse-engineer or gain unauthorised access to the Space or its providers; do not use it to send spam or unlawful material; and do not misrepresent our content as personalised medical guidance. We may block access that threatens the Space or other readers.

09:00 — Outside resources

The Space may mention books, studies, products or other websites. Such mentions are informational and are not endorsements, and the HerSpace Keepers receive no payment for them unless clearly disclosed alongside the mention. Third-party sites are governed by their own terms.

10:00 — Warranty disclaimer

The Space is offered on an as-is, as-available basis. As far as the law allows, the HerSpace Keepers make no warranties of any kind, express, implied or arising by statute, about the Space, including any warranty that it will be accurate, uninterrupted, error-free or suited to your particular needs.

11:00 — Limitation of liability

Within the outermost limits the law permits, the HerSpace Keepers are not liable for any lost sleep, lost profits, lost data, or indirect, special, incidental, exemplary or consequential damages, and their combined liability for all claims of any kind relating to the Space is limited to thirty-five U.S. dollars ($35).

These limits do not apply where the law forbids them, for example to liability for fraud or for injury caused by gross negligence.

12:00 — Dispute resolution

Notice and talks. A Riser or the HerSpace Keepers who wish to raise a dispute must first send written notice (for us, to support@circadianherspace.com) describing the issue and the relief sought. The parties will then have 60 days to resolve it informally, and any limitation period is paused during that time.

Arbitration. Unresolved disputes arising out of or relating to these Terms or the Space will be settled by final, binding arbitration before a single arbitrator administered by ADR Services, Inc., held remotely unless both parties agree otherwise. The Federal Arbitration Act governs. Any filing or arbitrator fee you are asked to pay beyond the amount you would pay to file in court will be reimbursed by the HerSpace Keepers for claims under $10,000 that are not frivolous.

Many similar claims. If 25 or more substantially similar arbitration demands are filed by or with the help of the same counsel or coordinated group, they will proceed in stages: ten selected cases will be decided first, the parties will then mediate the rest in good faith, and any remaining cases will be arbitrated in further groups of ten. Limitation periods are paused for all cases while they wait.

No class proceedings. Disputes will be handled only on an individual basis. Class, collective, consolidated and representative actions and arbitrations are not permitted.

Small claims and injunctions. Either party may take an individual claim to small claims court, and either party may seek a court order to protect intellectual property.

Opt-out. Within 30 days of first using the Space, you may decline this arbitration section by emailing support@circadianherspace.com with your name, the address you use with us and a clear statement that you opt out. Disputes will then be resolved in a court with jurisdiction.

13:00 — Governing law

United States federal law, including the Federal Arbitration Act, governs these Terms. Questions not addressed by federal law will be decided under widely accepted principles of U.S. contract law, without regard to conflict-of-law rules.

14:00 — Ending access and changes

You may stop using the Space at any time. We may modify, suspend or discontinue the Space, or end your access, without notice. We may update these Terms; material changes will be announced in Sunrise Notes or on the site at least 14 days before they apply, and using the Space afterwards means you accept them. Sections that by their nature should continue, including those on intellectual property, disclaimers, liability and disputes, survive termination.

15:00 — Other terms

If a court or arbitrator finds part of these Terms unenforceable, that part will be limited to the minimum extent necessary and the remainder will continue. A delay in enforcing any right is not a waiver. The HerSpace Keepers may assign these Terms to a successor publisher; you may not assign them. We may give you notice by email or by posting on the Space. These Terms and the Privacy Policy make up the entire agreement concerning the Space and replace earlier versions.
