Your files never leave your browser

What we do not collect

• No file uploads. Your MT5 XML/CSV/HTML reports are read in memory and discarded when you close the tab.
• No accounts, no registration and no tracking cookies. Nothing we measure can be tied back to your files.
• We do not see your EA parameters, optimization results or strategy logic.

What stays only on your device

The browser may store locally (never sent to us): your color theme, language preference, the minimums you set — so you do not have to re-enter them — and your analysis history: a short summary of each analysis (file and parameter names, minimums, number of passes, evidence level, the recommended pass with its values, plateau range, robustness and quality, the unseen-period result if you checked it, a short code computed from the figures to recognize the same data when you analyze it again, and the labels you add), never your files. The history is used to compare when you analyze an EA again; you can turn it off or delete it in the app’s History tab. You can clear everything by wiping site data for this domain.

What we measure: anonymous visits and feature use

We use GoatCounter on every page, and Cloudflare Web Analytics on every page except the app, to count how many people visit the site and how often each feature is used: for example, “an analysis was run”, “it failed” or “a .set was downloaded”. What is sent is the address and title of the page visited, the page you came from and the screen width; when you use the app or click some buttons on the site, also the name of that event. Neither uses cookies or follows you across websites, and neither can see your files, EA parameters or results. As with any web request, these services receive your IP address; according to their policies, they do not use it to identify you. The GoatCounter script is served from orometra.com itself, so no page runs code loaded from its servers.

What we cannot avoid

The host that serves the website (GitHub Pages) logs, like any web server, basic data about each request: IP address, time and browser. It is unavoidable when serving a page and unrelated to the content of your optimization files.

If you write to us

You can reach us at hello@orometra.com. If you write, we only use your address to reply. Please do not attach your optimization files unless you want us to look at a specific problem.

Who is responsible and your rights

• Controller: Pol Lázaro. Contact: hello@orometra.com.
• Personal data processed: the IP address and basic browser data received by the host and the analytics services when you visit the site, and your email address if you write to us. Your MT5 files are never received.
• Purpose and legal basis: measuring how the site is used in order to improve it, and replying to your messages. The basis is our legitimate interest (Art. 6.1.f GDPR); in the case of emails, also the fact that you chose to write.
• Recipients: GitHub (hosting), Cloudflare and GoatCounter (analytics). GitHub and Cloudflare are US companies and may process data outside the EU under the safeguards they offer.
• Retention: emails are kept for as long as needed to answer them and follow up; analytics are kept as aggregate statistics.
• Your rights: you can request access, rectification, erasure, objection, restriction or portability by writing to hello@orometra.com, and lodge a complaint with the Spanish Data Protection Agency (aepd.es).

Disclaimer

Orometra is a statistical analysis tool, not financial advice. A favorable evidence grade is not a recommendation to buy, sell or fund an EA. Past results do not guarantee future performance. Orometra is not affiliated with MetaQuotes; MetaTrader and MQL5 are trademarks of MetaQuotes Ltd.

• Backtest results do not predict future results. That sentence is repeated so often it has lost force, so it is worth saying precisely: everything this app measures happened in the past, and the market has no obligation to repeat itself.
• Output quality depends entirely on your data quality. If your backtest used a poor history, an unrealistic spread or ignored commissions, the analysis will inherit those defects without being able to detect them.
• Trading with leverage can make you lose more than you invest. Responsibility for any decision you make is entirely yours.
• The tool is offered as is, with no warranty of availability, accuracy or fitness for any particular purpose.

Terms of use

• Use requires no signup. There is no guarantee the page will always be available or maintained indefinitely.
• You may use the results freely, including commercially, under your own responsibility.
• The application code and its methodology are the property of its author, published under the PolyForm Noncommercial license: you may view, use and modify it for noncommercial purposes; commercial use of the code itself needs permission.
• If you find an error in the calculations, report it to hello@orometra.com: a bug in a tool like this can cost someone money, and that matters more than any other consideration.
