Terms of Service
Last updated: July 2026
1. Acceptance of terms
By accessing or using NNS Tax Pro ("the Service"), you agree to be bound by these Terms of Service. If you do not agree, do not use the Service.
2. Description of service
NNS Tax Pro is an automated calculation tool that parses NNS transaction exports, applies UK Section 104 pool cost basis, and produces realized-gains reports in GBP. The Service is provided for informational purposes only.
NNS Tax Pro is an automated calculation tool and does not constitute formal accounting, tax, legal, or financial advice. The outputs generated by the Service are computational summaries of the data you submit and are not a substitute for advice from a qualified, regulated professional. No accountant-client, tax-advisor-client, or fiduciary relationship is formed by your use of the Service.
3. Eligibility and authentication
Access to the dashboard requires authentication via Internet Identity. Your data is keyed to your principal and isolated from other users. You are responsible for maintaining the security of your Internet Identity.
4. Payment and unlock
Report downloads are unlocked via a one-time Stripe Checkout payment. Payments are processed by Stripe in test mode during this release. Unlock is permanent for your principal and grants access to both PDF and JSON downloads. Refunds are handled at our discretion; contact support for assistance.
5. Accuracy of calculations
While NNS Tax Pro applies UK Section 104 methodology, you are responsible for verifying the accuracy of all calculations and for ensuring your NNS export is complete and correct. The Service is not a substitute for professional tax advice.
6. Acceptable use
You agree not to misuse the Service, attempt to access other users' data, reverse-engineer the canister, or submit malformed inputs intended to disrupt operation. Per-user data isolation is enforced at the canister level.
7. Intellectual Property & Anti-Copying
All software code, Section 104 calculation engine logic, report layouts, algorithms, text, graphics, and design elements on NNS Tax Pro are the exclusive intellectual property of NNS Tax Pro and protected by UK and international copyright laws. Unauthorised copying, reproduction, distribution, reverse engineering, scraping, or creation of derivative works from any part of this system or its exported reports is strictly prohibited without prior written consent.
8. Limitation of liability
The Service is provided "as is" without warranties of any kind, express or implied. To the maximum extent permitted by law, we are not liable for any direct, indirect, incidental, or consequential damages arising from your use of the Service or reliance on its calculations.
You maintain sole and exclusive responsibility for your tax filings, including the preparation, review, accuracy, and timely submission of any returns to HM Revenue & Customs (HMRC) or any other tax authority. The Service does not file, submit, or amend any return on your behalf.
Under no circumstances shall the platform operator, its affiliates, officers, employees, or contributors be liable for any HMRC penalties, HMRC audits, HMRC interest charges, or court summonses arising from your use of the Service, your reliance on its calculations, or your failure to obtain independent professional advice. This limitation applies regardless of whether such penalties, audits, interest, or summonses arise from calculation errors, data omissions, misinterpretation of outputs, or any other cause.
9. Indemnification
You agree to indemnify, defend, and hold harmless the platform operator, its affiliates, officers, employees, and contributors from and against any and all claims, liabilities, damages, losses, costs, and expenses — including HMRC penalties, HMRC audit costs, HMRC interest charges, and court summonses — arising out of or in connection with your use of the Service, your reliance on its calculations, your submission of any return to HMRC or any other tax authority, or your breach of these Terms.
The platform operator bears no liability whatsoever for any HMRC penalties, audits, interest, or court summonses incurred by you or any third party. You acknowledge that the operator does not review, verify, approve, or endorse any filing you make, and that all filing decisions and their consequences rest with you alone.
10. Changes to terms
We may update these Terms from time to time. Continued use of the Service after changes constitutes acceptance of the revised Terms.
