Weight99 is designed to deliver its core comparison without an account, saved profile or personal-weight history. This page describes the current pre-launch beta behavior rather than promising features or data practices that are not connected today.
This beta page documents the product as currently implemented. Formal operator/contact details, jurisdiction-specific notices and final legal review must be completed before Weight99 is treated as publicly launched.
The live product does not currently provide user accounts, cloud profiles or a saved personal comparison-history feature.
Weight99 currently uses GET query parameters for the Compare experience so the state can be reproduced and corrected without an account.
A comparison URL can contain values such as weight, unit, country, age and sex-reference selection. That means those values can appear in your browser history, a copied URL and ordinary hosting/request logs.
Do not paste or forward a full comparison URL unless you are comfortable sharing the values visible in that URL. Weight99 share-card and Visual Story assets are generated from an allowlisted result/share contract instead of publishing the intake form as a public share payload.
The current PNG/share flow is intentionally separate from account storage and public-result URLs.
The current compare/share/story instrumentation is a browser-local semantic event seam, not a connected analytics provider. The same provider-neutral seam now also records coarse Explore hub entry/path categories.
The event contracts allow only coarse product semantics such as compare surface and rendered success/error outcome; Explore hub entry and broad path category; and share/story surface, artifact type, aspect ratio, bounded visible-card count, presentation, customization and action/outcome categories. They are designed not to carry raw weight, age, country/population identity, percentile, result/story IDs, destination URLs, query strings or user/session identifiers.
The current emitters perform no analytics network request, persistence, cookie access or user/session-ID work. If Weight99 later connects an analytics, advertising or consent provider, this page must be updated to describe that real behavior and any consent choices required for the markets served.
Accountless does not mean that no technical data exists anywhere in the delivery path.
Optional demographic fields exist only to choose a source-defined comparison reference when the production data supports it.
Weight99 does not infer sex-reference or age from names, images, location, language or other proxies. The current comparison models are adult-oriented; under-20 comparison is accepted only where an exact production route explicitly supports that age, currently including Australia ages 18–24.
These references are descriptive statistical contexts, not profile identities, diagnoses or health classifications.
Weight99 should not silently add a persistence provider, identity layer, third-party analytics transport, advertising tracker or materially different share/public-state behavior while this page continues to describe the current beta architecture.
