Neyrren Trade Helper Privacy Policy

Neyrren Trade Helper processes marketplace page data locally to provide tools for analyzing and recording CS2 item trades. Most extension data, including settings, module states, saved filters, presets, and calculator preferences, is stored using browser-managed extension storage.

The extension does not sell user data, use it for advertising, determine creditworthiness, or track the user's general browsing history.

The optional CsTradeBook integration is disabled by default. When the user enables it, provides an API key, and explicitly creates or updates a deal, the extension may send the following information to https://cstradebook.com:

• the CsTradeBook API key;
• item and marketplace names;
• purchase and sale prices;
• marketplace fees;
• purchase and sale dates;
• listing, order, or transaction identifiers;
• listing URLs;
• deal status and user-provided notes.

This information is transmitted only to provide the CsTradeBook integration requested by the user. The extension does not collect payment card numbers, bank account information, credit ratings, passwords, or unrelated website content.

The extension may request exchange-rate data from https://open.er-api.com. This request does not include marketplace page content, saved filters, API keys, or deal information.

Users can stop CsTradeBook data transmission by disabling the integration or removing the API key from the extension settings. Extension settings can be removed by resetting the extension or uninstalling it. Data already submitted to CsTradeBook is governed by the CsTradeBook Privacy Policy and can be managed through the user's CsTradeBook account.
