Terms of Service

1. Who can use the Service

You must be at least 16 years old, or the age of digital consent where you live if that is higher. If you use the Service on behalf of an organization, you confirm that you have authority to bind it, and "you" includes that organization.

2. Your account

You sign in with a Google account or with an email address and password. You are responsible for keeping that account secure and for everything done through your Bluefeather account. Tell us promptly at hello@bluefeather.ai if you believe someone else has used it. One person may not hold more than one account without our permission.

3. What the Service does

Bluefeather measures text. It scores a draft for patterns that read as machine-generated or padded, computes a profile of how you write from samples you save, and compares drafts against that profile. It does not write text for you; rewriting is done by you or by an AI assistant you choose to use. Scores, profiles, and writing types are statistical descriptions, not judgements of quality, authorship, or authenticity, and we make no promise about how any third party, including an AI-detection tool, will treat text you have edited with Bluefeather.

4. Acceptable use

You agree not to:

• Use the Service to misrepresent who wrote something where authorship matters, including submitting work as your own in violation of an academic, professional, or contractual honesty requirement.
• Use the Service to deceive, defraud, defame, harass, or harm anyone, or to produce content that is unlawful where you or the recipient are located.
• Submit text you do not have the right to process, or that contains other people's personal data you are not entitled to share.
• Probe, scan, overload, or interfere with the Service, bypass rate limits or access controls, or access it by any automated means other than the documented assistant integrations.
• Reverse engineer the Service, resell it, or build a competing product using it, except as permitted by law.

We may suspend or close accounts that break these rules or that threaten the Service or other users.

5. Your content

You keep all rights to the text you submit and the samples you save ("Your Content"). You give us a limited, non-exclusive, worldwide licence to host, process, and display Your Content solely to provide the Service to you and as described in the Privacy Policy. This licence ends when you delete the content, subject to short retention in backups and logs as described there. We do not use Your Content to train or improve any machine learning model and we do not share it with other users.

You are responsible for Your Content and confirm that you have the rights needed to submit it.

6. Writing samples and your voice profile

Samples must be your own writing. The profile computed from them is only as representative as the samples you choose, and comparisons against it are guidance, not a guarantee that text will read a particular way to any reader. You can delete samples at any time; deleting all of them removes the profile.

7. AI assistants and third-party services

You may use the Service through ChatGPT, Codex, Claude, or another compatible assistant. Those products are provided by their own operators under their own terms and privacy policies, which govern your conversation with them. We are not responsible for an assistant's output, including any rewrite it produces using Bluefeather's measurements, and we do not control what the assistant does with your conversation. Google sign-in is provided by Google under Google's terms.

8. Beta status and changes to the Service

The Service is in beta. Features may change, pause, or be withdrawn, and measurements may be recalibrated, which can change scores, profiles, and writing types. We will try to give notice of material changes but cannot promise to. We may also set limits on usage, such as the number or size of samples.

9. Fees

The Service is currently free. If we introduce paid plans, we will publish the prices and terms before charging anyone, and nothing in these terms obliges you to pay for features you have not chosen to buy.

10. Our intellectual property

The Service, including its software, measurements, writing types, design, text, and trademarks, is owned by Bluefeather or its licensors and protected by intellectual property laws. Subject to these terms, we grant you a personal, non-exclusive, non-transferable, revocable licence to use the Service. No other rights are granted.

11. Feedback

If you send us suggestions or feedback, you agree we may use them without restriction or compensation. We will not claim that feedback came from you without your permission.

12. Termination

You may stop using the Service at any time and may ask us to delete your account by emailing hello@bluefeather.ai. We may suspend or terminate your access if you breach these terms, if required by law, or if we discontinue the Service, with notice where reasonably possible. Sections 5, 10, 11, and 13 to 18 survive termination.

13. Disclaimers

The Service is provided "as is" and "as available". To the fullest extent permitted by law, we disclaim all warranties, express or implied, including merchantability, fitness for a particular purpose, and non-infringement, and we do not warrant that the Service will be uninterrupted, error-free, or that any measurement will be accurate or suitable for any purpose. Nothing in these terms limits rights that consumers have under mandatory law.

14. Limitation of liability

To the fullest extent permitted by law, Bluefeather will not be liable for any indirect, incidental, special, consequential, or punitive damages, or for lost profits, revenue, data, or goodwill, arising from or related to the Service, however caused. Our total liability for all claims relating to the Service in any twelve-month period is limited to the greater of the amount you paid us in that period and 50 euros. These limits do not apply to liability for intent or gross negligence, or where they cannot be limited under applicable law.

15. Indemnity

If you use the Service on behalf of an organization, that organization will defend and indemnify Bluefeather against claims arising from Your Content or your breach of these terms. This section does not apply to consumers.

16. Governing law and disputes

These terms are governed by the laws of the Netherlands. Disputes will be brought before the competent court in Amsterdam, unless mandatory consumer law gives you the right to a court in your own country of residence. Consumers in the European Union may also use the European Commission's online dispute resolution platform. Before going to court, please email us; most issues can be resolved directly.

17. Changes to these terms

We may revise these terms. The date at the top shows the current version. For material changes we will give at least 14 days' notice by email or inside the Service. Continued use after the effective date means you accept the revised terms; if you do not, stop using the Service and ask us to delete your account.

18. General

These terms, with the Privacy Policy, are the entire agreement between you and us about the Service. If any part is found unenforceable, the rest remains in effect. Our failure to enforce a term is not a waiver. You may not assign these terms without our consent; we may assign them to a successor of the Service. Notices to you may be sent to the email address on your account.
