More price lookups.
A plan that fits.

No. Both are free and use no credits. Click a highlighted term in a product name or description, or open the full dictionary from the popup or Tools. Switch appearance beside VN/EN in the popup; Settings also offers System. This marketing website’s theme button is separate from your extension preference.

There is no automatic cloud sync. Personal entries stay in the browser extension. Export and import a ZIP through Settings → Backup & transfer. The ZIP may contain an unencrypted API key; keep it private.

Notes stay in the browser extension; they are not sent to the server or automatically synced to the cloud. Export a ZIP from Settings → Backup & transfer, then drop it into the extension on the new device. The ZIP contains an unencrypted API key, so keep it private and back up before uninstalling or clearing browser data.

No. Separate daily allowances per network: 3 products for API price lookups, 1 for price/warranty history, 1 for title/description history and 3 for change checks. Without a key or with an expired key, click to check. A valid key automatically checks unlimited products. Repeat checks and variant changes use no extra credits that day; reset is at 00:00 UTC+7.

C+ Changed appears when wholesale, flashsale or warranty differs between the last two recorded days. Open it for before/after details. With a saved selling price, the extension estimates profit impact using the cost, fees and quantity captured when saved. Selling prices and these settings stay on your device. Checks use imported observations, not real-time data; warranty comparison needs two known recorded days.

History only exists for days the system has imported and recorded. One recorded day is enough to show one price point. Successful daily imports add observations even if prices stay unchanged; same-day reruns update that day’s last observation. Missing days are not fabricated. Try one history product/day free, or use a valid key for unlimited products.

No. Member purchase prices visible on CNLG allow free, unlimited calculations. An API key unlocks CNLG+ price lookups, 7/30/60/90-day history and automatic price/warranty change checks for unlimited products.

Without a key: 3 products/day per network. One product is one credit, including its variants. Revisiting that product or changing its profit goal that day uses no additional credits. The quota resets at 00:00 UTC+7.

These are costs outside the platform fee schedule: packaging, storage, ads, affiliate commissions, tax and shop-specific expenses. They are not mandatory platform fees. Ads may still be provided by the platform and tax may be withheld by it.

It is an estimate based on your cost and settings. Check the category, incentives and actual expenses before setting a price. Not all vouchers, returns or shop-specific programs are modeled.
