By creating an account or using Verbum 11 ("the Service"), you agree to these Terms and Conditions. If you do not agree, please do not use the Service.
Verbum 11 is a research and organization tool for Kindle Direct Publishing (KDP) niche research. You can upload Amazon pages saved as PDF or structured competitor data. The Service uses AI to extract and summarize supported information and calculates a rule-based score using formulas you can view and adjust. AI output and third-party product data may be incomplete or inaccurate and must be reviewed by you. Amazon, Kindle, and KDP are trademarks of Amazon.com, Inc. or its affiliates. Verbum 11 is an independent tool and is not affiliated with, endorsed by, or sponsored by Amazon.
You must provide a valid email address to create an account, or sign in with a Google account. The Service is not directed to children under 16, and you must be at least 16 years old to create an account. You are responsible for keeping your login credentials secure and for all activity that happens under your account. Tell us right away if you believe your account has been accessed without your permission.
Anything you upload, including PDFs, spreadsheets, niche data, notes, and scoring settings, remains yours. We store it so the Service can function, and it is never shared with other users. You can export your data at any time, and you can delete your account and associated data from your account settings, subject to backups and legal retention. You confirm that you have the right to upload and process the content you submit.
You agree not to:
Scores, rankings, and estimates shown in the Service, including the estimated monthly revenue figure, are calculated from the numbers you provide using fixed formulas, or are rough industry approximations, and are provided for informational purposes only. They are not a guarantee of sales, income, or success, and are not financial, business, or publishing advice. You are solely responsible for any decisions you make based on information from the Service. AI-assisted analysis, listing suggestions, and cover briefs are working material, not legal, publishing, or professional advice. You must check output before relying on it, publishing it, or submitting it to a third party. You are responsible for any disclosure or labelling required where you use AI-assisted output publicly.
Verbum 11 is currently a personal testing project. No paid subscriptions, payment processing, checkout, automatic renewal, or paid upgrade is active in the Service. Access may be free, invited, limited, or subject to AI, file-size, concurrency, and rate limits. If paid access is introduced later, the applicable price, renewal, cancellation, withdrawal, and refund terms will be presented before a purchase can be completed. Third-party API usage is paid by the operator unless the Service explicitly offers a bring-your-own-key option.
You may delete your account at any time from your account settings. This permanently removes your uploads, niches, scores, and notes, and cannot be undone. We may suspend or terminate accounts that violate these terms.
The Verbum 11 name, visual identity, original website copy, interface designs, documentation, scoring presentation, and underlying software belong to the operator or its licensors and are protected by applicable copyright and intellectual property laws. These terms give you a limited, non-exclusive, non-transferable right to use the Service for its intended purpose. They do not permit copying, republishing, selling, licensing, reverse engineering, or creating derivative commercial services from protected parts of Verbum 11 without prior written permission. Your uploaded files, notes, and original research remain yours, and you retain the rights you already hold in that content.
If you believe material stored through the Service infringes your copyright, contact us at 21bluesupport@gmail.com with enough detail to identify the work and the material at issue. We review valid reports and may remove or restrict access to material where appropriate. Repeated infringement may result in account suspension or termination. The reporting and counter-notice process is described on our Copyright and DMCA page.
The Service is provided "as is" without warranties of any kind, express or implied. We do not guarantee the Service will be uninterrupted, error free, or that any score or estimate will be accurate.
To the fullest extent permitted by law, Verbum 11 is not liable for any indirect, incidental, or consequential damages arising from your use of the Service, including business or publishing decisions made based on it.
We may update these terms from time to time. If we make material changes, we will update the date at the top of this page. Continuing to use the Service after a change means you accept the new terms.
These terms are governed by the laws of Romania. Courts with jurisdiction under applicable Romanian law will resolve disputes, except where mandatory consumer-protection law gives you a different right or forum that cannot be excluded by these terms.
Questions about these terms can be sent to 21bluesupport@gmail.com.
