Terms of Service — ContentGrapher

Effective date: 18 May 2026

Operator: Daniel K Cheung (ABN: 97 136 392 116) ("ContentGrapher", "we", "us", "our")

1. Acceptance of Terms

By accessing or using ContentGrapher at contentgrapher.io (the "Service"), you agree to these Terms of Service ("Terms"). If you do not agree, do not use the Service.

You must be at least 16 years old to use the Service. By using the Service, you confirm you meet this age requirement.

Using the Service constitutes acceptance of these Terms. If you use the Service on behalf of an organisation, you represent that you have authority to bind that organisation to these Terms.

2. Description of Service

ContentGrapher is a content analysis tool for content teams, technical writers, and publishers. It analyses the structural completeness of explanatory content for AI retrieval purposes.

What ContentGrapher does:

• Ingests a URL or submitted text
• Maps the concept graph of what is present in your content — including integration states, relationships, and naming consistency
• Builds an ideal explanation framework for your topic and audience from first principles
• Generates specific writing guidance: what to add, what to clarify, and what relationships to make explicit
• Produces a page architecture and boundary map identifying which concepts belong on the page versus elsewhere
• Tracks improvement across re-analyses via a delta view

What ContentGrapher does not do:

• Benchmark your content against competitor or top-ranking pages
• Measure keyword frequency, density, or readability scores
• Analyse social media content
• Make editorial decisions on your behalf — outputs are a tool to assist your judgment, not replace it
• Provide keyword research, backlink analysis, or any other traditional SEO function

Analysis outputs reflect structural patterns in your content and the explanation framework generated for your topic and audience. They do not constitute professional advice of any kind. As recommended by Anthropic's terms covering AI-generated content, factual assertions in analysis outputs should not be relied upon without independently checking their accuracy.

3. Account Registration

3.1 Creating an account

Authentication is via magic link sent to your email, or via Google OAuth. There are no passwords. You must provide an accurate email address. You are responsible for maintaining the security of your login credentials and email account.

3.2 One account per user

Each person may hold one account. Creating multiple accounts to circumvent credit limits or free-tier allowances is prohibited.

Free-tier analyses are tracked per browser device (via a device token stored in your browser), not per email address. Switching browsers or clearing browser storage may reset the free-tier counter — this is the intended behaviour. Programmatically creating new device tokens to obtain additional free analyses is prohibited.

3.3 Accuracy of information

You must provide accurate, current information when registering. If your information changes, update it promptly.

3.4 Account security

You are responsible for all activity that occurs under your account. Notify us immediately if you suspect unauthorised access.

4. Credits and Billing

4.1 Free tier

New users receive 5 free analyses, tracked via a device token stored in your browser. Free analyses do not require account registration. Free-tier credits and purchased account credits are independent: free-tier credits do not merge into a paid account when you sign up. A logged-in user with zero purchased credits will fall back to any remaining free-tier credits associated with their device.

Free-tier credit expiry. Free-tier credits expire 12 months from the date your device was first registered with the Service, which occurs the first time you visit ContentGrapher. Creating an account after your device is registered does not extend or reset this window. Unused free-tier credits are forfeited on expiry with no refund or compensation.

Free-tier usage is subject to fair-use limits described in Section 5.

4.2 Credit packs

Paid access is via one-time credit pack purchases. No subscription is required.

How credits are consumed:

• One credit is consumed per completed Phase 2 analysis
• Phase 1 analysis (initial concept extraction) is always free and does not consume credits
• Re-running Phase 1 to correct a detected topic anchor does not consume a credit
• Re-analysing the same content (including content that has not changed since a prior analysis) consumes a credit each time, because the analysis runs in full
• If your account contains multiple active credit packs, credits are consumed from the oldest-expiring pack first

If a Phase 2 analysis fails before completing due to a system error or a pipeline gating failure, the credit will be returned to your account.

4.3 Expiry

Credits expire 12 months from the date of purchase. Unused credits are forfeited on expiry. We aim to send a reminder email approximately two months before expiry (around month 10) if you have unused credits remaining, but this email is informational and not a guarantee.

4.4 Non-refundable

As a goodwill exception, if you have not used any analyses from a newly purchased pack, you may request a full refund within 7 days of purchase by emailing privacy@contentgrapher.io. Once any analyses from the pack have been consumed, the pack is non-refundable except as required by applicable consumer protection law.

Credit packs are non-refundable except as required by applicable consumer protection law. Pricing is stated in USD.

4.5 Payment processing

All payments are processed by Stripe. ContentGrapher does not store your payment card details. Stripe's terms of service and privacy policy apply to all payment transactions.

4.6 Pricing changes

We may change credit pack prices at any time. Price changes do not affect credits already purchased. We will give reasonable notice of price changes.

5. Acceptable Use

You may use the Service only for lawful purposes and in accordance with these Terms. The following uses are prohibited:

1. Infringing third-party intellectual property. Submitting content that infringes copyright, trade marks, or other intellectual property rights of any third party.

1. Scraping or paywall circumvention. Using the Service as a mechanism to scrape, crawl, or otherwise circumvent access controls on third-party websites or paywalled content.

1. Submitting third-party personal data. Submitting URLs or content that contains personally identifiable information (PII), health data, financial data, or any other sensitive personal data of third parties without their consent.

1. Reverse engineering. Attempting to decompile, disassemble, reverse-engineer, or otherwise derive the source code, algorithms, or methodology underlying the analysis pipeline.

1. Reselling or sublicensing outputs. Reselling, sublicensing, or commercially redistributing analysis outputs as a standalone product or as part of a competing service. (Use of outputs in client deliverables is governed by Section 7.)

1. Illegal purposes. Using the Service for any purpose that is unlawful in your jurisdiction or that violates any applicable regulation.

1. Automated bulk submission. Submitting URLs or content via automated scripts, bots, or any non-human means at volumes materially exceeding normal individual usage patterns, without prior written agreement.

1. Account or device-token abuse. Sharing account credentials, pooling credit balances with individuals outside a single licensed user (except where explicitly permitted by a future Team-tier agreement), or programmatically generating device tokens to extend free-tier allowances.

1. Impersonation or false information. Impersonating any person or organisation, or providing false registration information.

We reserve the right to determine, at our reasonable discretion, whether use constitutes a violation of these Terms.

6. User Content

6.1 Ownership

You retain all ownership rights in the content you submit to the Service — including URLs, text content, and audience specifications you provide ("User Content"). These Terms do not transfer any intellectual property rights to ContentGrapher.

6.2 Licence to process

By submitting User Content, you grant ContentGrapher a limited, non-exclusive, worldwide, royalty-free licence to process, transmit, and store that content solely for the purpose of providing and improving the Service to you.

6.3 Analysis corrections

By submitting an analysis correction, you grant ContentGrapher a licence to use the anonymised correction data (topic, audience type, field name, and corrected values — no content or identifiers) to improve analysis quality.

6.4 Model training and third-party processing

ContentGrapher does not use your User Content to train its own models. The Service sends your User Content to the Anthropic Claude API for analysis. Under Anthropic's Commercial Terms, Anthropic does not train its models on content submitted through the API, and Anthropic processes such content as a data processor on ContentGrapher's behalf.

Anthropic may retain API inputs and outputs for a limited period for operational, safety, and legal-compliance purposes. ContentGrapher does not have the ability to trigger ad-hoc deletion of individual API requests from Anthropic's systems. For full details, see Anthropic's Commercial Terms of Service at https://www.anthropic.com/legal/commercial-terms and Anthropic's API data-handling FAQ at https://privacy.claude.com/en/articles/7996875-can-you-delete-data-that-i-sent-via-api.

6.5 Storage of outputs

Analysis outputs — including Phase 1 concept maps, Phase 2 explanation frameworks, page architecture and boundary maps, writing guidance, and delta comparisons — are stored and associated with your account so you can access analysis history and re-analysis deltas.

Analysis history persistence is available only for authenticated accounts. Anonymous free-tier users do not receive persistent server-side history; their analyses are accessible only via their browser session.

You may delete your account and associated data as described in Section 10.

6.6 Your responsibility for content

You are solely responsible for the User Content you submit. You represent and warrant that you have all rights necessary to submit the content and to grant the licence in Section 6.2.

7. Intellectual Property

7.1 ContentGrapher's property

ContentGrapher's brand, logo, user interface, underlying system architecture, analysis pipeline, and all software code are the exclusive property of Daniel K Cheung. Nothing in these Terms grants you any rights in these materials.

7.2 Analysis outputs

The analysis outputs generated by the Service (concept maps, explanation frameworks, page architecture and boundary maps, writing guidance, delta reports) are produced by ContentGrapher's pipeline and are owned by ContentGrapher. Subject to your compliance with these Terms and payment of applicable credits, ContentGrapher grants you a non-exclusive, non-transferable licence to use analysis outputs for:

• Your own internal content improvement purposes
• Inclusion in client deliverables (reports, audits, content strategy documents) where the output is presented as part of your professional work product

You may export your account data, including analysis outputs, as a JSON file via the Account page export feature, and share these exports with your clients, colleagues, or stakeholders for the purposes described above. A per-analysis PDF export for client deliverables is on the near-term roadmap.

7.3 Restrictions on outputs

You may not:

• Commercially redistribute analysis outputs as a standalone product
• Incorporate analysis outputs into a competing content analysis or AI retrieval optimisation service
• Remove ContentGrapher attribution or branding from exported reports

7.4 Shareable links

The Service may allow you to generate read-only shareable links for specific analyses. When you generate such a link:

• You are responsible for the content of the analysis you share and for choosing recipients appropriate to the underlying content
• Anyone who accesses an analysis via a shareable link is bound by the output-use restrictions in Section 7.3
• You may revoke or expire shareable links at any time via the in-app controls
• ContentGrapher is not responsible for any disclosure caused by your sharing of a link

8. Disclaimer of Warranties

THE SERVICE IS PROVIDED "AS IS" AND "AS AVAILABLE" WITHOUT WARRANTIES OF ANY KIND, EXPRESS OR IMPLIED.

TO THE MAXIMUM EXTENT PERMITTED BY APPLICABLE LAW, CONTENTGRAPHER DISCLAIMS ALL WARRANTIES INCLUDING, WITHOUT LIMITATION:

• That analysis results are accurate, complete, or fit for any particular purpose
• That the Service will be uninterrupted, error-free, or free of harmful components
• That any defects will be corrected
• That the Service meets your specific content or business requirements

ContentGrapher is a tool to assist content decisions. Analysis outputs reflect a structural diagnosis of your content based on AI interpretation. They are not a substitute for editorial judgment, professional advice, or your own assessment of your content strategy.

Results may vary depending on the nature of the content submitted, the audience specification provided, and other factors outside ContentGrapher's control.

9. Limitation of Liability

TO THE MAXIMUM EXTENT PERMITTED BY APPLICABLE LAW:

9.1 Nothing in this Section 9 limits or excludes ContentGrapher's liability for:

(a) death or personal injury caused by ContentGrapher's negligence; (b) fraud or fraudulent misrepresentation; (c) any right you have under the Competition and Consumer Act 2010 (Cth), including the Australian Consumer Law, or equivalent non-excludable consumer protection rights under the law of your jurisdiction; (d) any right you have as a data subject under applicable data protection law, including the right to compensation under Article 82 of the GDPR where that right cannot be contractually excluded.

9.2 Subject to clause 9.1, ContentGrapher is not liable for any indirect, incidental, special, consequential, or punitive damages, including but not limited to loss of profits, loss of revenue, loss of data, loss of business opportunity, wasted expenditure, cost of corrective action, or reputational damage — even if ContentGrapher has been advised of the possibility of such damages.

9.3 Subject to clause 9.1, ContentGrapher's total aggregate liability to you for all claims arising out of or in connection with these Terms or the Service is limited to the greater of:

(a) the total amounts paid by you to ContentGrapher in the twelve (12) months immediately preceding the event giving rise to the claim; or (b) USD $50.

This clause 9.3 does not limit your obligation to pay amounts owed for Services rendered.

9.4 Where the Australian Consumer Law or equivalent legislation implies a guarantee into these Terms that cannot be excluded, ContentGrapher's liability for a breach of that guarantee is limited, to the extent permitted by law, to resupplying the relevant Service or paying the cost of having it resupplied.

9.5 The limitations in this Section 9 reflect a reasonable allocation of risk, having regard to the nature of the Service and the fees charged. ContentGrapher relies on these limitations as a condition of providing the Service at its current pricing.

10. Termination

10.1 Termination by you

You may close your account at any time via the account settings page in the Service, or by emailing privacy@contentgrapher.io. Account closure takes effect within a reasonable period following your request.

If you close your account while you still hold unused purchased credits, those credits are forfeited (consistent with the non-refundable policy in Section 4.4) unless required otherwise by applicable law.

10.2 Termination by ContentGrapher

We may suspend or terminate your account immediately if:

• You breach these Terms
• We reasonably suspect fraudulent, abusive, or unlawful activity
• Required to do so by law or a regulatory authority

We will provide notice of termination where reasonably practicable and not legally prohibited. Where we terminate your account for a breach of these Terms, unused purchased credits are forfeited.

10.3 Effect of termination

On account termination:

• Your right to access the Service ceases immediately
• Your User Content and analysis history will be deleted in accordance with our Privacy Policy retention schedule

Sections that by their nature should survive termination (including Sections 7, 8, 9, 12, and 13) will survive.

11. Modifications to Terms

We may modify these Terms at any time. For material changes, we will provide at least 14 days' notice via email to the address associated with your account.

Continued use of the Service after the notice period constitutes your acceptance of the updated Terms. If you do not agree to the updated Terms, you must stop using the Service before the effective date of the changes.

The current version of these Terms will always be available at contentgrapher.io/terms.

12. Governing Law

These Terms are governed by and construed in accordance with the laws of New South Wales, Australia, without regard to its conflict of law principles. Nothing in this clause limits any mandatory consumer rights you may have under the laws of your country of residence.

13. Dispute Resolution

Any dispute arising out of or in connection with these Terms shall be subject to the non-exclusive jurisdiction of the courts of New South Wales, Australia.

Nothing in this clause prevents either party from seeking urgent injunctive relief from a court of competent jurisdiction.

16. General Provisions

Entire agreement. These Terms, together with our Privacy Policy, constitute the entire agreement between you and ContentGrapher regarding the Service.

Severability. If any provision of these Terms is found to be unenforceable, that provision will be modified to the minimum extent necessary to make it enforceable, and the remaining provisions will continue in full force.

No waiver. Failure to enforce any provision of these Terms does not constitute a waiver of our right to enforce it in the future.

Assignment. You may not assign your rights or obligations under these Terms without our prior written consent. We may assign our rights and obligations freely, including in connection with a merger, acquisition, or sale of assets.

Force majeure. Neither party is liable for failure to perform obligations due to causes beyond their reasonable control, including natural disasters, acts of government, or third-party service failures.
