Privacy policy

Data you enter into the tools

Barcode values, bulk lists, validator input and camera frames are processed entirely by JavaScript running on your own device. None of it is transmitted to us or stored on a server, and we therefore cannot see, retrieve or disclose it.

Files you download are generated locally by your browser. Anything you keep in the tool disappears when you close or reload the page.

Advertising and Google AdSense

This site displays advertising through Google AdSense to keep the tools free.

Google and its partners use cookies and similar technologies to serve and measure ads. These may be used to track your activity across this and other websites in order to show ads based on your prior visits, to limit how often you see the same ad, and to detect invalid traffic. Google's use of advertising cookies enables it and its partners to serve ads to you based on your visit to this site and/or other sites on the internet.

You can opt out of personalised advertising at any time in Google's Ads Settings at adssettings.google.com. You can also opt out of third-party vendor cookies at aboutads.info/choices or youradchoices.com, and manage cookies directly in your browser settings. Opting out does not remove ads — it means the ads you see are no longer tailored to you.

If you are in a region covered by the GDPR or similar rules, a consent notice is presented before non-essential advertising cookies are set, and you can change or withdraw that choice at any time.

For details of how Google handles data as an advertising provider, see Google's own privacy policy at policies.google.com/technologies/partner-sites.

Analytics

We use privacy-friendly, aggregated analytics to count page views and see which tools are used. It records coarse technical information such as page path, referrer, approximate country, and browser and device type. It does not build a profile of you, and we never combine it with the barcode data you enter — which, as above, we do not receive at all.

Cookies used on this site

• Advertising cookies — set by Google AdSense and its partners, as described above. These are the main cookies on this site.
• Consent cookie — remembers your advertising consent choice where a consent notice applies, so you are not asked on every visit.
• We do not set cookies for logins, carts or tracking you between sessions, because the site has no accounts.

Where our content and data come from

• Barcode rules — lengths, character sets and check-digit algorithms are implemented from the published GS1 General Specifications and the applicable ISO/IEC standards.
• Rendering — barcode images are produced on your device by bwip-js, an open-source library. It runs locally and makes no network requests of its own.
• Sample values — invented for demonstration; they do not come from, and are not checked against, any product database.
• We hold no product, company or consumer database, and we buy or sell no personal data.

Email you send us

If you write to service@barcode.best, we keep your message and address for as long as needed to deal with your enquiry and any follow-up. It is not used for marketing and not shared with anyone else.

Children

The site is a general-purpose utility and is not directed at children under 13, and we do not knowingly collect personal information from them.

Your rights and choices

Depending on where you live, you may have the right to access, correct or delete personal data held about you, to object to processing, or to opt out of the sale or sharing of personal information. Because we operate no accounts and receive no barcode data, the data we could hold about you is limited to any email correspondence and the third-party advertising and analytics records described above.

To exercise a right, or to ask what we hold, email service@barcode.best. For advertising data held by Google, use Google's own controls linked above.
