Privacy Policy
What we collect, what we refuse to collect, and how measurements are handled.
Your measurements never leave your browser. The calculator runs on your device. Nothing you type into it is sent to our servers, written to a database, placed in a URL, recorded in a log or passed to any advertising or analytics service.
About this website
Bra Size Guide is an independently operated informational website based in Western Australia. It is not currently operated through a company or other legal entity. Privacy questions and requests can be sent through our contact page.
Your measurements
- Measurements are processed entirely in your browser using JavaScript. No network request carries them.
- They are not stored in a cookie, in local storage, in your browsing history or in a shareable link.
- Your unit preference – centimetres or inches – is kept in session storage so the page remembers it while your browser tab is open. It is a preference, not a measurement, and it is discarded when you close the tab.
- If JavaScript is disabled, the form submits to our server so the calculation can run there. In that case the measurements appear in a single request, are used to produce the page you see, and are not written to a database. Server access logs are configured to exclude request bodies.
- Our contact form does not ask for measurements and we ask that you do not send them.
What we collect
| What | Why | Retention |
|---|---|---|
| Analytics events | To understand site usage and whether the calculator is usable. Calculator analytics use coarse event information and never include raw measurements or an exact calculated size. | According to our Google Analytics settings and Google’s applicable retention policies. |
| Server logs | Security, abuse prevention and diagnostics. These may include an IP address, user agent, requested URL and timestamp, but not calculator request bodies. | Only for legitimate security and operational needs, then deleted or anonymised according to hosting settings. |
| Contact form | To respond to your enquiry. This may include your name, email address and message. | Until the enquiry is resolved and the information is no longer reasonably required. |
| Advertising cookies | Set by our advertising partners where permitted and subject to your consent choices. | According to the relevant advertising provider’s policy. |
Cookies, analytics and advertising
Essential storage keeps necessary site features working. Google Analytics helps us understand aggregated site usage. If Google AdSense advertising is enabled, Google and other third-party vendors may use cookies or similar technologies to serve, measure and personalise advertising, subject to applicable consent requirements.
Third-party vendors, including Google, may use advertising cookies to serve ads based on a visitor’s previous visits to this website or other websites. You can manage Google advertising personalisation through Google Ads Settings. You can also review industry opt-out choices at AboutAds.
Where required, visitors are shown a Google-certified consent message before analytics or advertising technologies use consent-dependent storage. You can change or withdraw a previous choice through the privacy choices control provided on the site.
Service providers
Information may be processed by service providers needed to operate the site, including our website host, security services, Google Analytics and, when enabled, Google AdSense and participating advertising technology providers. These providers may process information in Australia or overseas under their own terms and privacy policies.
Google explains how it uses information from sites using its services on its partner sites information page. We do not sell personal information.
Your choices and requests
You may ask what personal information we hold about you, request a correction or deletion where appropriate, or raise a privacy concern through our contact page. Because calculator measurements are not retained, we cannot retrieve a past measurement or calculated result.
Sensitive information
Body measurements are personal, which is why the calculator is designed not to retain them. Please do not include measurements, medical details or other sensitive information in a contact message. If sensitive information is sent voluntarily, it will be deleted when the enquiry is resolved and it is no longer reasonably required.
Children
This site is not directed at children and we do not knowingly collect information from anyone under 15. A parent or carer helping someone else measure should read our measuring guide, which is written to be used that way.
Changes
Changes to this policy will be published on this page. The policy took effect on 10 August 2026 and was last updated on 18 August 2026.
