Privacy and use of the tools.

The link may contain your calculation.

The calculator writes parameters into the address, such as profile, days, solar panel, selected appliances and usage hours. The share button copies that link to the clipboard when your browser permits; it does not send a message itself.

Updating the address with JavaScript does not itself send a calculation request to the server. However, opening or reloading the link sends the URL and its parameters to the host to request the page, and it may appear in history, provider technical logs or services where you share it. Any recipient can read those parameters. Do not add names or sensitive information, and take special care when sharing medical equipment configurations.

The comparison may also include model identifiers in the URL. We do not claim that no consumption data reaches servers: we lack sufficient evidence about retention and access to all hosting logs.

What your browser stores.

• theme, in local storage: light or dark mode preference.
• ep_compare_ids, in local storage: identifiers of models added to the comparison. Clearing the comparison removes the selection; you can also delete site data in your browser.
• Calculation parameters remain in the URL and may stay in history. The application does not create an account associated with them.

Technical requests and analytics.

Vercel receives the requests needed to serve the website, with technical connection information. Fonts and local images are served from this site; some panel photos load from manufacturer servers, which receive those requests. No connected visitor analytics provider or transmission of calculations to our own API has been found.

The public version does not include the testing panel or its action log. Consented diagnostics are reserved for the private QA environment. This does not remove technical logs kept by hosting or external services; their terms and retention must be checked separately.

Links to stores and sources.

Opening Amazon or a documentary source takes you out of Nelpuni, and that service applies its own policy. Amazon affiliate links include the project account identifier. Purchase attribution and commissions received remain unverified; the identifier's presence does not guarantee that result.

The current website has no integrated checkout and receives no delivery or order data through these links. We do not control how a store processes the data you provide.

Responsible party and pending details.

Declared owner: Ricard Caula Triadú. Contact: nelpuni.contact@gmail.com.

The address provided by the owner appears in the legal notice. Support and data-rights procedures, and provider processing and retention terms still need to be completed and verified. This information is not presented as legal certification. Do not enter personal data expecting a service this version does not offer.
