Stockport is not a SEBI-registered Investment Adviser under the SEBI (Investment Advisers) Regulations, 2013. Nothing on this platform — including articles, tool outputs, XIRR/TWRR calculations, behavioural analysis, or any other content — constitutes investment advice, a recommendation to buy or sell any security, or a solicitation of any investment. All content is educational and informational only. You are solely responsible for your investment decisions.
The XIRR vs TWRR Calculator analyses historical tradebook data you upload and returns mathematical computations. These outputs describe your past behaviour — they do not predict future returns and should not be used as the basis for any specific investment decision.
Stockport's articles and frameworks describe general investing principles and discipline practices. They do not constitute personalised advice for your specific financial situation.
We collect the minimum data needed to provide the service. Here is exactly what we collect and why:

| Email address | Early access form; XIRR tool email gate | Formspree (US) → forwarded to our inbox | Until you unsubscribe or request deletion |
| Tradebook files (CSV/XLSX) | Uploaded to XIRR calculator | Processed in server memory only — not stored | Deleted immediately after processing |
| Stock price data | Fetched from Yahoo Finance for TWRR | Supabase database (anonymised market data, no PII) | Indefinite |
| Page analytics | Cloudflare Web Analytics | Cloudflare (aggregated, no personal data, no cookies) | 30-day rolling aggregate |

You may use Stockport for personal, non-commercial portfolio analysis and educational purposes. You agree not to reverse-engineer or scrape the platform, submit malicious data, use the platform for any unlawful purpose, or attempt to compromise platform security.
All content on Stockport — articles, frameworks, tool design, and code — is owned by Stockport. You may share links freely. You may not reproduce, republish, or resell content without written permission.
Calculations depend on the completeness and correctness of data you upload. Corporate action handling (splits, bonuses, mergers) is approximate; affected symbols are flagged in results. Historical price data is sourced from Yahoo Finance and subject to their availability and accuracy. Results are mathematical outputs, not predictions.
To the fullest extent permitted by applicable law, Stockport and its founder shall not be liable for any investment losses, financial decisions made based on tool outputs or articles, data inaccuracies arising from incomplete tradebook uploads, or any indirect, consequential, or incidental damages arising from use of this platform.
These terms are governed by the laws of India. Any disputes shall be subject to the exclusive jurisdiction of the courts in New Delhi, India.
We may update these terms periodically. Material changes will be noted with an updated "Last updated" date at the top of this page. Continued use of the platform after changes constitutes acceptance of the revised terms.
