NibFlow Terms of Service & Privacy Notice

1.1 These terms apply to NibFlow websites, desktop applications, and related account, AI, subscription, payment, download, and support services (the “Services”). By creating an account, purchasing a subscription, or continuing to use the Services, you agree to these terms.

1.2 This website and its services are operated and owned by Yu Se Tech. Yu Se Tech is the service provider for the international edition of NibFlow.

1.3 If you use the Services for an organization, you confirm that you are authorized to accept these terms on its behalf.

2.1 NibFlow is a local-first writing environment for long-form and structured narratives, including novels, nonfiction, short drama, and screenplays. Features may include project organization, editing, context management, Discuss / Act / Write collaboration, model access, import/export, and subscription metering.

2.2 AI features support ideation, research, rewriting, and editing. They do not replace independent judgment and are not legal, medical, financial, publishing, or other professional advice.

2.3 Some features may be experimental, in preview, or under active development. Current functionality, platforms, models, quotas, and limits are those shown in the product.

3.1 Provide accurate and necessary account information and protect your device and credentials. You are responsible, to the extent permitted by law, for losses caused by voluntarily sharing credentials or failing to take reasonable security measures.

3.2 Users under the age of majority must use the Services with a parent or guardian’s approval. Additional verifiable consent may be required for children’s personal data.

3.3 Contact us promptly about unauthorized access, security issues, or unexpected charges. We may verify identity or temporarily restrict access to protect the account and Services.

4.1 You or the lawful rights holder retain all rights in text, settings, materials, files, and other content you create, import, edit, or submit (“User Content”). NibFlow does not acquire ownership merely by providing the Services.

4.2 You grant us a limited, non-exclusive license to process User Content only as needed to perform an operation you request—such as conversion, export, AI processing, support, or security—and to comply with law. This license lasts only as long as necessary for that purpose.

4.3 NibFlow does not claim ownership of AI output. Whether an output is protected, exclusive, or similar to existing material depends on applicable law and the creative process. Review outputs before publishing or commercial use.

4.4 NibFlow software, interfaces, trademarks, documentation, and service technology belong to us or their licensors. Open-source components remain subject to their respective licenses.

5.1 AI output is probabilistic and may be inaccurate, incomplete, biased, inappropriate, or similar to third-party material. You decide whether to adopt, edit, publish, or rely on it and remain responsible for the final work.

5.2 BYOK and third-party models are governed by your arrangement with the provider. NibFlow Subscription requests may pass through NibFlow service interfaces to a connected model provider for processing, metering, security, and troubleshooting.

5.3 Do not submit personal data, trade secrets, classified information, confidential unpublished material, or other highly sensitive content unless you have authority and have applied appropriate safeguards.

5.4 If output carries legally required AI-generated content labels, you must not maliciously remove, alter, forge, or conceal them and must follow applicable disclosure rules when distributing the content.

7.1 You must have the right to process submitted content and comply with intellectual property, privacy, confidentiality, cybersecurity, publishing, and generative-AI laws.

7.2 Do not use the Services for unlawful or harmful content, infringement, privacy violations, fraud, harassment, discrimination, malicious marketing, cyberattacks, bypassing safeguards, automated abuse, or interference with the Services.

7.3 We may warn, restrict, suspend, preserve necessary records, terminate, or report unlawful or high-risk use in proportion to its severity and will provide an appeal channel where required.

8.1 Free editor features and paid AI features are described in the product and pricing page. AI usage varies with model, input/output length, context, tool calls, and service cost and is metered under the displayed rules.

8.2 Price, currency, term, taxes, renewal status, and key benefits are shown before purchase. Payment providers process the transaction; we receive the status needed to fulfil and support the order.

8.3 If a plan renews automatically, we will provide legally required notice before enrollment and renewal and a practical cancellation method. Cancellation normally takes effect at the end of the paid term.

8.4 Refund requests must be submitted to contact@nibflow.ink within 14 days of purchase. If none of the AI credits included with the purchase have been used, we will issue a full refund; if some credits have been used, we will refund the unused portion on a pro-rata basis. Refunds are processed by Paddle, our Merchant of Record. This clause does not limit mandatory consumer rights under applicable law. The complete Refund Policy is available at https://nibflow.ink/refund-policy.

8.5 Upgrade, downgrade, term change, and proration rules are those shown at the time of the action. Nothing here removes your right to cancel future renewal or exercise mandatory consumer rights.

9.1 We may adjust features, models, quotas, or supported platforms for security, compliance, supplier, technical, or business reasons. Material adverse changes to paid benefits will receive reasonable advance notice and an appropriate remedy where required.

9.2 Maintenance, network failure, third-party outages, force majeure, or security incidents may interrupt the Services. We will take reasonable steps to reduce disruption but cannot promise uninterrupted or error-free operation.

9.3 You may stop using the Services, cancel renewal, or request account closure. Terms concerning accrued payments, IP, confidentiality, liability, and disputes survive termination where appropriate.

10.1 To the extent permitted by law, the Services and AI outputs are provided as available. We do not warrant that output is always accurate, original, fit for a particular purpose, or suitable for publication or professional use.

10.2 We will reasonably assist with issues involving third-party model, identity, payment, or network services, while each provider remains responsible under its terms and applicable law.

10.3 Keep independent backups of important manuscripts. We are not responsible beyond applicable law for local file loss caused by device failure, user error, malware, or events outside our reasonable control.

10.4 To the extent permitted by law, we are responsible for foreseeable direct loss. Except for fraud, gross negligence, personal injury, privacy violations, or liability that cannot legally be limited, aggregate liability is capped at the fees paid to NibFlow in the twelve months before the event giving rise to the claim.

11.1 We may update these terms as law, product features, or data practices change. Material changes affecting important rights, paid benefits, or personal-data processing will be announced before taking effect through the website, application, email, or another reasonable channel.

11.2 Updated terms do not automatically rewrite completed transactions. If you disagree with a material change, you may stop using the affected Services and cancel future renewal before it takes effect, subject to mandatory law.

12.1 The China edition is governed by the laws of the People’s Republic of China. The international edition may also be subject to mandatory laws of the provider’s and user’s jurisdictions.

12.2 The parties should first attempt good-faith resolution through support. If unresolved, either party may bring a claim before a court with lawful jurisdiction, and consumers may use available regulatory or consumer complaint channels.

12.3 If a provision is invalid or unenforceable, the remaining provisions remain effective and the affected provision will be interpreted as closely as legally possible to its intended effect.
