TRANSPARENCY ABOUT DATA

CNLG+ Privacy Policy

CNLG+ is an independent extension for viewing purchase prices and estimating selling prices and profit on CNLG. For support and data requests, contactZalo 0915670892or0915670892.

1. Data processed by the extension

• Product content on cungnhaulamgiau.vn: product IDs, SKUs, names, categories and visible prices, used to identify products, suggest categories and calculate prices.
• Your API key, costs, profit goals, categories, language and display preferences are stored locally in the extension. Entered selling prices are saved by product, variant and sales channel, with the purchase cost and fee settings captured when saved, to estimate profit impact when source prices change. These selling plans are not uploaded to CNLG+ servers.
• To confirm member pricing, the extension reads the session response from/api/auth/sessionon CNLG and uses the flaggood_pricing === "T". The full session is never stored or transmitted. Only after you consent in Settings does the extension extract user_id, username, email and mobile/phone when provided by CNLG. CNLG SIDs, cookies, tokens and passwords are never sent to CNLG+.
• Private product/SKU notes stay in extension local storage and are not sent to the server or sellers. You can export and import a ZIP to move settings, your API key, saved selling prices and notes to another browser/device. The ZIP includes an unencrypted API key; you keep and transfer it yourself, and the extension never uploads it. Clearing browser data or uninstalling may delete notes that have not been backed up.
• The glossary includes built-in CNLG+ terms for offline lookup. Terms, aliases and explanations you add stay in your browser and are not sent to the server or sellers. ZIP backups can transfer personal terms; imported terms replace matching names and preserve unrelated entries.

2. Data sent to the CNLG+ service

When looking up prices through the API athttps://don.chordmint.app, the extension sends the requested product ID/SKU and, if provided, your API key for authentication. Your browser also provides connection information such as your IP address to the server. Free mode uses network identity to enforce the limit of three products per day. Service status and API access checks may occur in the popup or when displaying API data.

Purchase prices read directly from the CNLG interface are calculated locally without requesting a CNLG+ price lookup. Your costs, profit goals and entered selling prices are not sent to the CNLG+ API. Your API key is not sent to CNLG or placed in the product interface.

For change checks, the extension sends the product ID to the CNLG+ API to retrieve the last two recorded price/warranty days. A valid key checks automatically; free access checks only after a button click, with a separate allowance of 3 products/day per network. This allowance is independent of price and history lookups.

Title and description history allows 1 free product/day per network; a valid API key provides unlimited access. The extension sends the product ID to check for earlier versions without spending a credit. When you request a comparison or export, it sends the product ID, revision IDs and API key (if configured) to CNLG+; the server checks access and quotas. The server stores source wording and shop information from successful imports, creating a revision only when the content changes. This archive is separate from price history and does not automatically use the 90-day price window. Comparison data is not persisted in extension storage; a JSON file is downloaded only when you explicitly export it. Source content is displayed as text and its HTML is never executed.

3. Purpose and sharing

With consent, the extension sends an activity heartbeat at most every 15 minutes, including when using prices already on CNLG. It uses no credits and sends no product URLs or browsing history.

The API records hourly operational metrics: request counts, endpoints, HTTP status, latency and extension version. Networks are HMAC-hashed; analytics tables do not store raw IP addresses. Approximate IP regions are used only from explicitly trusted proxy headers. Otherwise the region is unknown; no GPS or third-party geolocation service is used.

Account sharing is optional, off by default and does not affect features or allowances. When enabled, API calls send a random installation ID, the four account fields above and an optional self-reported province/city to don.chordmint.app. Only MintPos administrators can access this for support and service improvements, never advertising or data sales. The extension-supplied identity is not verified by CNLG and grants no API access.

Data is used to provide prices, estimate profit, verify API access and manage quotas. The extension contains no advertising code, ad trackers or third-party analytics. It does not sell browsing data or use it for personalized ads. Connections to CNLG and the API service use HTTPS.

Zalo links open only when you choose to contact us. Information you send through Zalo is processed by that service and used for support and issuing API keys.

4. Storage and control

Metrics use a rolling 90-day window and are pruned periodically. Shared account data is pruned after 90 days of inactivity. Disable sharing in Settings to stop sending account data; Turn off sharing and erase shared data removes the profile and metrics linked to that installation. A hashed opt-out marker prevents queued requests from recreating erased data. If the server cannot be reached, the extension reports that erasure has not completed and lets you retry. This does not erase settings, API keys, source prices or allowances.

Local settings remain until you change them, clear data or uninstall the extension. You can remove your API key in Connection. API prices are temporarily cached in the extension process to reduce duplicate requests; the member-pricing flag is used for no more than 30 seconds before being checked again. Clearing browser data does not automatically erase quotas or data processed by the server.

The server processes authentication records, quota information and operational data for the API. Contact 0915670892 about data associated with your key/network, server retention or data requests. Do not send your CNLG password when requesting support.

5. Access scope and policy changes

The extension runs on CNLG and connects to the API service described above. It does not request access to all websites, browser history or cookie management. You can disable the extension or its suggested-price calculator in Connection. If data handling changes, this policy and the product information will be updated accordingly.

6. The CNLG+ website

This website provides product, pricing and contact information. It has no data-collection forms, accounts or automatic payments. English is selected through /en URLs; no cookies or analytics are used to store that choice. The demo calculator runs in your browser and does not send costs or settings to a server.

The website is hosted on Vercel. The hosting provider may process IP addresses and HTTP request information for content delivery, security and hosting operations.

Marketplace lookups send the product ID and SKU when available to MintPos. The comparison page sends an offer ID, action type and random event ID to count views and clicks. When you choose to visit Shopee, Shopee handles the visit under its own policies. Affiliate buttons are labeled on the page.
