| Category | Details | How | Destination |
|---|---|---|---|
| Account data | Phone number, password (hashed), optional invite code | You enter at registration/login | Our servers (Alibaba Cloud, China) |
| On-page product data | Public info of the product page you are viewing: product ID, title, price, sales, stock, rating, review count, image URLs (Wildberries, Ozon, Yandex Market, Amazon, 1688) | Read locally on the page as you browse | Processed locally in your browser by default; uploaded only when you actively use cloud features |
| User-created content | Favorites, compare lists, pick libraries, tracked products, price-alert settings | When you click the corresponding feature | Our servers (linked to your account, or to an anonymous ID if logged out) |
| Analysis requests | Product titles you submit to "Keyword Analysis" | On your explicit action | Our servers (returns keyword popularity only) |
| Anonymous identifier | A random 64-char string generated by the extension (no identity info) | Auto-generated on install | Our servers (quota & data isolation for logged-out use) |
| Local settings | Login token, UI settings, privacy choices, local caches | Written at runtime | chrome.storage.local only — never leaves your device |
We do NOT collect: browsing history (beyond public info on product pages listed above), keystrokes, geolocation, contacts, payment information, or anything unrelated to the single purpose of cross-border profit calculation.
Profit calculation, currency conversion, image download and CSV export run entirely locally in your browser. Cloud sync (favorites/compare/pick library), price & keyword-rank tracking with drop alerts, and keyword popularity analysis use our servers only for the data you actively submit. Registration, login and membership validation use your phone number and password hash. Optional AI features (VIP/credits) use the same account on haisenai.com, a system operated by the same entity — no data flows outside. A public exchange-rate request to cbr-xml-daily.ru carries no user information. All processing is strictly limited to the single purpose described above — no profiling, no behavioral tracking, no ad targeting.
Data is stored in your browser (chrome.storage.local) and on our servers hosted by Alibaba Cloud in China. Account data is kept until account deletion; user-created content until you delete it or close the account; anonymous-ID data for up to 12 months; server logs for up to 90 days. Passwords are stored as irreversible hashes; all transmission is encrypted via HTTPS/TLS; server APIs enforce authentication and rate limits.
Prior consent: on first run the extension shows a summary of this policy and asks for your explicit consent before sending any data to our servers. Offline mode / opt-out: you can enable "Disable data collection" anytime in the extension popup — all processing then stays local and cloud features pause, while local features (profit calculation, image download, CSV export) keep working. Access, correction, deletion: you may delete favorites/compare/library items anytime; for account deletion or full data removal, email us and we will process it within 7 business days. Withdraw consent: via the opt-out switch or by uninstalling the extension.
storage (local settings/token), alarms (price-tracking schedules), notifications (price-drop alerts), downloads (image/CSV export), host access to listed e-commerce domains (render the panel and read public product info on pages you visit), host access to chaojimaijia.cn (our own API).
The extension targets business sellers and does not knowingly collect data from minors. Changes to this policy will be posted on this page with the date updated; material changes will be announced inside the extension.
