How this analyzer handles your data
This page distinguishes two separate things: the electricity meter data you analyze, which is processed by the analyzer in your browser, and the ordinary website requests needed to load the site itself. It also states what third-party tooling the application uses today and what would need to change before any is introduced.
Your meter file
When you choose a CSV or XLSX file, it is read by your browser. Parsing, timestamp normalization, data-quality checks, analysis and the two what-if scenarios run locally in your browser.
The analyzer does not upload your meter file to a server and does not send the analysis results, statistics or scenario assumptions to a server. Normalized CSV exports are generated locally from data already held by the analyzer.
The application does not persist your meter file or analysis results between sessions. They are held only in page and worker memory while the analyzer is open.
What is stored in your browser
The application does not store your meter file or analysis results in the browser. It does not keep them in local storage or session storage, does not place them in a browser database and does not set any cookie of its own on this site. Analyzed meter data is not persisted between sessions: closing or reloading the page discards it.
Ordinary website traffic
Loading this website involves ordinary web requests for the page and its assets, as any website does. The infrastructure serving those requests can receive standard information associated with a web request, such as an IP address, browser user-agent information and the time of the request. This is separate from your electricity interval data, which is not part of those requests.
Third-party services today
The application currently includes no analytics, advertising, affiliate tracking, user accounts, subscription or payment system, and no cloud-saved analyses. That describes what this application implements; it is not a statement about any infrastructure logging that accompanies the ordinary web requests described above.
If this changes
This page will need to be updated before functionality such as analytics, advertising, affiliate tracking, user accounts, cloud-saved analyses, subscriptions or payments, or any server-side processing of meter data is introduced. More about the product itself is on the about page.
