xbbTools
Privacy Policy
Last updated: June 7, 2026
Information You Provide
xbbTools lets you enter product prices, dimensions, weights, costs, sales volumes, and other calculation inputs directly in your browser. You choose what to type into each tool.
Do not enter passwords, API keys, payment card numbers, or other credentials into calculator fields. Those fields are designed for product and packaging data only.
Calculator Inputs and Server Requests
Profit Calculator and Packaging Optimizer send calculation inputs to xbbTools application servers through the site’s API routes so results can be computed. Length and Weight Converters also send conversion values to the conversion API when you edit a unit.
xbbTools does not intentionally store calculator inputs as user profiles or account records. The site does not offer sign-in today. Requests may still pass through application and hosting infrastructure and may appear temporarily in operational logs where technically necessary for security, debugging, and service operation.
Local Storage
The website uses browser local storage to remember interface preferences. The known key today is xbb-tools-language, which stores your selected display language (English or Chinese).
This preference is not an account login credential. You can clear it through your browser settings; after clearing, the site returns to its default language behavior.
Server Logs and Technical Data
Hosting and application servers may process standard technical information such as request time, browser type, requested page, response status, and IP address for security, diagnostics, and service operation.
These logs support reliability and abuse prevention. Retention depends on hosting configuration and operational needs.
Google Analytics
When NEXT_PUBLIC_GA_MEASUREMENT_ID is configured for the deployment, xbbTools loads Google Analytics through Next.js third-party integration. If that identifier is not set, Google Analytics is not enabled on the site.
Google Analytics may use cookies or similar technologies to collect information about page views, device and browser characteristics, interactions, and site performance. Google processes this data under its own policies.
You should not send personally identifying information to Google Analytics through calculator fields. You may manage related data through browser settings, Google’s opt-out tools, or future consent controls if those are introduced.
Cookies and Similar Technologies
In addition to language local storage, cookies or similar technologies may be used when analytics is enabled or when future services are activated.
xbbTools does not require an account and does not use advertising cookies today. This section will be updated if additional cookies are introduced.
Advertising and Google AdSense
xbbTools does not display Google AdSense or other third-party advertising on the site today.
If advertising is enabled in the future, Google and other vendors may use cookies or similar technologies to serve and measure ads, including ads based on prior visits to this site or other sites, subject to consent and applicable settings. The Privacy Policy will be updated before advertising is activated.
You may manage personalized advertising preferences through Google’s advertising settings when those services apply.
Consent for EEA, UK, and Switzerland Users
If xbbTools enables analytics or advertising technologies that require consent in the European Economic Area, the United Kingdom, or Switzerland, the site will provide an appropriate consent mechanism before those technologies run in a consent-required manner.
Google advertising in those regions may require a Google-certified Consent Management Platform. Until such consent is obtained where required, xbbTools will not enable consent-dependent storage or personalized advertising in those modes.
Third-Party Services and Links
Hosting, source-control, analytics, and infrastructure providers may process limited technical information as necessary to operate the website. Their privacy terms may apply.
xbbTools links to Amazon and other external sites for reference. Those sites have their own privacy practices.
Data Retention
Language preference remains in your browser until you clear it. Server and hosting logs are retained for operational periods defined by infrastructure providers, not as a permanent archive of calculator inputs.
If retention practices change, this policy will be updated.
Data Security
Reasonable technical measures are used to protect the service. However, no online system can guarantee absolute security.
Do not transmit sensitive account credentials through calculator tools or general contact email.
Children’s Privacy
xbbTools is intended for business and seller planning use and is not directed at children under 13. We do not knowingly collect personal information from children.
Your Choices and Requests
You can clear local storage and cookies through your browser. You can choose not to use optional analytics when it is disabled by configuration.
