The Services may include, without limitation:

Free educational content is provided for informational and instructional purposes. It is not a substitute for personalized professional advice tailored to your business, legal, tax, or medical situation.

3. Eligibility

You represent that you are at least 18 years of age (or the age of majority in your jurisdiction) and have legal capacity to enter into these Terms. The Services are intended primarily for adults operating coaching or related professional practices.

4. Accounts, subscriptions, and communications

When you submit your email address (and, where requested, your name) to a form, you request to receive the corresponding sequence or list communications. Delivery is provided through third-party email platforms, currently including Kit for free course automation and, after the applicable free course path, Substack for publication-related email.

You agree to provide accurate information and to keep your contact details current. You may unsubscribe using links in emails or by contacting us. Operational or transactional messages related to a purchase or legal notice may still be sent where permitted by law.

Double opt-in, confirmation emails ("Day 0"), reCAPTCHA, and similar anti-abuse measures may apply. We may refuse, suspend, or remove subscriptions that appear fraudulent, abusive, or in violation of these Terms.

5. Free educational materials - no guarantees

Free courses and related materials teach methods, frameworks, and exercises (including Challenge Newsletter concepts). You retain full responsibility for how you apply the material to your business.

We do not guarantee, and nothing in the Services should be understood as a promise of:

Results depend on your effort, market, offer, skill, timing, and factors outside our control. Testimonials or examples, if any, are illustrative only and not typical results.

6. Paid services

Paid ghostwriting or other commercial services are governed by these Terms and by any written proposal, statement of work, order form, invoice, or contract between you and us (a "Service Agreement"). If a Service Agreement conflicts with these Terms on a commercial term (price, scope, delivery, refund), the Service Agreement controls for that engagement.

Fees are due as stated on the invoice or Service Agreement. Unless expressly stated otherwise in writing, fees are non-refundable once work has commenced. Late payment may pause delivery.

Payment processing may be handled by third-party processors. You authorize us and those processors to charge the payment method you provide for agreed amounts and applicable taxes.

7. Intellectual property

Subject to your rights in materials you lawfully own and provide to us, the Services (including site design, copy, course content, templates, frameworks, branding, logos, and software configuration) are owned by the Operator or licensors and are protected by intellectual property laws.

We grant you a limited, non-exclusive, non-transferable, revocable license to access free materials for your personal or internal business learning. You may not resell, republish, sublicense, or commercially redistribute our course content, templates, or branding as a competing product without prior written consent.

For paid ghostwriting, ownership and license of deliverables are as set out in the Service Agreement. Absent a contrary written term, you receive a license or assignment only as expressly stated in that agreement.

Feedback you submit may be used by us to improve the Services without obligation to you, unless a separate written agreement says otherwise.

8. Acceptable use

You agree not to:

9. Third-party services

The Services rely on third parties, including Kit, Substack, hosting providers, analytics tools, Notion or similar asset hosts, and payment processors. Those services are subject to their own terms and privacy policies. We are not responsible for outages, policy changes, or acts of third parties beyond our reasonable control.

10. Privacy

Processing of personal information is described in our Privacy Policy, which is incorporated by reference. By using the Services, you consent to that processing to the extent required to deliver the Services and as permitted by law.

11. Disclaimers

TO THE MAXIMUM EXTENT PERMITTED BY APPLICABLE LAW, THE SERVICES ARE PROVIDED "AS IS" AND "AS AVAILABLE," WITHOUT WARRANTIES OF ANY KIND, WHETHER EXPRESS, IMPLIED, OR STATUTORY, INCLUDING IMPLIED WARRANTIES OF MERCHANTABILITY, FITNESS FOR A PARTICULAR PURPOSE, TITLE, AND NON-INFRINGEMENT.

We do not warrant that the Services will be uninterrupted, error-free, or free of harmful components, or that content will meet your expectations or produce any particular business outcome.

12. Limitation of liability

TO THE MAXIMUM EXTENT PERMITTED BY APPLICABLE LAW, THE OPERATOR SHALL NOT BE LIABLE FOR ANY INDIRECT, INCIDENTAL, SPECIAL, CONSEQUENTIAL, EXEMPLARY, OR PUNITIVE DAMAGES, OR ANY LOSS OF PROFITS, REVENUE, DATA, GOODWILL, OR BUSINESS OPPORTUNITY, ARISING OUT OF OR RELATED TO THE SERVICES OR THESE TERMS, WHETHER BASED IN CONTRACT, TORT (INCLUDING NEGLIGENCE), STRICT LIABILITY, OR OTHERWISE, EVEN IF ADVISED OF THE POSSIBILITY OF SUCH DAMAGES.

TO THE MAXIMUM EXTENT PERMITTED BY LAW, OUR TOTAL LIABILITY FOR ANY CLAIM ARISING OUT OF OR RELATING TO THE SERVICES OR THESE TERMS SHALL NOT EXCEED THE GREATER OF: (A) THE AMOUNTS YOU PAID TO US FOR THE SPECIFIC PAID SERVICE GIVING RISE TO THE CLAIM DURING THE THREE (3) MONTHS BEFORE THE CLAIM; OR (B) ONE HUNDRED UNITED STATES DOLLARS (USD 100) IF YOU ONLY USED FREE SERVICES.

Some jurisdictions do not allow certain limitations; in those cases, our liability is limited to the fullest extent permitted.

13. Indemnity

You agree to indemnify and hold harmless the Operator from and against claims, damages, losses, and expenses (including reasonable legal fees) arising out of your misuse of the Services, your content, your violation of these Terms, or your violation of any third-party right, except to the extent caused by our willful misconduct.

14. Suspension and termination

We may suspend or terminate access to free or paid Services, in whole or in part, if you breach these Terms, if required by law, or if continued provision is impracticable. You may stop using free Services at any time and unsubscribe from emails. Provisions that by their nature should survive (including intellectual property, disclaimers, limitations, and indemnity) will survive termination.

15. Changes

We may modify the Services and these Terms from time to time. Updated Terms will be posted with a revised "Last updated" date. Material changes may be highlighted on the site or by email where appropriate. Continued use after changes become effective constitutes acceptance, except where mandatory law requires a different process.

16. Governing law and disputes

These Terms are governed by the laws of the Republic of Indonesia, without regard to conflict-of-law rules. Courts located in Jakarta, Indonesia shall have exclusive jurisdiction over disputes arising out of or relating to these Terms or the Services, subject to any mandatory rights you may have as a consumer in your place of residence.
