The source directory
A published rule description. Useful for terminology and for recognising that ace and house-rule conventions need a scope.
Read the source ↗A secondary overview of names and variation labels. It is not used as a legal or technical authority.
Read the source ↗First-party explanation of Play Protect behaviour and warnings.
Read the source ↗First-party guidance on reviewing device permissions; menus can differ between versions and devices.

Read the source ↗The Act itself. Read its exact provisions rather than relying on a slogan or an old summary.
Read the source ↗The government’s dated overview of the 2026 framework and its commencement.
Read the source ↗Version labels, internal build identifiers and their scope.
Read the source ↗General account-safety guidance; not a local incident-reporting service.
Read the source ↗Android platform requirements, distinct from a measured device test.
Read the source ↗How to use these references
Start with the source that matches your question. A card-game reference can explain a hand category but cannot certify a file. A developer tool can describe a signature check but cannot determine whether a commercial activity is permitted.
Sources were checked on 27 October 2026. External documents may later change or move. The relevant guide includes its own references so that the connection between a statement and its basis stays visible.
When evidence is missing
An empty field is not permission to invent an answer. We omit unsupported app versions, package names, fingerprints, ratings and download figures. Where the lack of information matters to the reader’s question, we explain that limit directly.
Our editorial policy describes the difference between an attributed statement, a measured observation and a test result.
