1. Data Collection
Amazon Listing Byte Checker is a pure frontend tool. All calculations, including UTF-8 byte counting, invisible character detection, and risk word highlighting, happen entirely in your browser. We do not collect, store, or transmit any personal data or listing content you paste into the tool.
We do not operate any backend server or database. Your listing text never leaves your device.
2. LocalStorage
We use the browser's LocalStorage API to remember your preferences, such as your selected Amazon marketplace (e.g., US, UK, DE) and language. This data is stored locally on your device and is not sent to any server.
LocalStorage does not store any sensitive information, listing content, or personally identifiable information. You can clear this data at any time by clearing your browser's site data.
3. Microsoft Clarity & Cloudflare Analytics
We use Microsoft Clarity to collect anonymized usage data, such as session recordings, heatmaps, and click tracking. This helps us understand how the tool is used and improve its features.
Clarity collects aggregated, anonymized data. We do not send any listing content or personal input to Clarity. You can opt out of analytics by using a browser extension that blocks tracking scripts.
We also use Cloudflare Analytics for traffic metrics such as page views, visitor geography, and bandwidth usage. Cloudflare Analytics is built into our hosting platform and does not require additional tracking scripts.
4. Cookies
This website uses cookies to provide essential functionality and to improve your experience. We use CookieYes as our cookie consent management platform, which allows you to accept or decline non-essential cookies at any time through the cookie banner or preference center.
Necessary cookies are required for basic site functionality and are always active. They do not store any personally identifiable information.
Analytics cookies (such as those set by Microsoft Clarity) help us understand how visitors interact with the website. These cookies are only activated after you provide explicit consent through the cookie banner. You can withdraw your consent at any time.
We do not use cookies for advertising purposes at this time. When advertising features are activated in a future version, additional cookies may be used, and we will update this policy accordingly.
5. Third-Party Services
We use the following third-party services:
- Microsoft Clarity: Anonymous session recordings, heatmaps, and click tracking to improve user experience. Only activated after you consent to analytics cookies. Microsoft Privacy Policy
- Cloudflare: CDN hosting, edge functions, and built-in traffic analytics. Cloudflare Privacy Policy
- CookieYes: Cookie consent management platform that records your cookie preferences. CookieYes Privacy Policy
We may include affiliate links to third-party tools (e.g., Helium 10,
Jungle Scout) in future versions. These links would redirect through
our /go/ directory, and the third-party tools have their
own privacy policies that govern any data you provide to them.
6. Your Data Rights (GDPR)
If you are a resident of the European Economic Area (EEA), you have certain data protection rights under the General Data Protection Regulation (GDPR). We aim to take reasonable steps to allow you to correct, amend, delete, or limit the use of your personal data.
You have the right to:
- Access — request a copy of the personal data we hold about you
- Rectification — request correction of inaccurate or incomplete data
- Erasure — request deletion of your personal data, where lawful
- Restriction — request restriction of processing of your data
- Objection — object to processing of your personal data
- Data portability — request transfer of your data to another organization
To exercise these rights, please contact us at feedback@vekehub.com. We will respond to all legitimate requests within 30 days.
Note: Since our tool runs entirely in your browser and we do not collect personal data through the tool itself, most of the above rights relate to analytics data collected through third-party services (see Section 5).
7. Children's Privacy
This service is not intended for children under the age of 13. We do not knowingly collect personal information from children under 13. If you believe we have collected information from a child under 13, please contact us immediately and we will take steps to remove such information.
