A lawn-bowls fieldbook

Explore line, length, bias, practice ends and rink courtesy through a private Android fieldbook.

A fieldbook, not a feed

Useful before the next bowl, quiet when the phone is put away.

Rink & Radius helps an adult form a clearer real-world observation. It has no public profile, chat, followers, streak pressure, ranking or remote engagement loop. Temporary tools reset locally; only accessibility choices and optional lesson bookmarks may remain on the device.

01

Bias Lab

Compare illustrative forehand and backhand arcs across short, medium and long visual lengths. The diagrams are conversation aids, never a prediction of a real bowl, person or green.

Enter the instrument
02

End Composer

Combine four fixed choices into a temporary practice sequence with setup, steps, observation, variation and reset. It creates no booking, draw, roster or official coaching plan.

03

Head Mapper

Move anonymous bowl tokens and a jack to discuss lanes and consequences without recording names, scores, teams, matches or official counts.

04

A decision can stay provisional.

Head Mapper and Green Notes deliberately use anonymous shapes and fixed, neutral language. They invite questions such as “What remains open?” and “What changes after contact?” without turning practice into a player database or pretending to determine a count.

The app does not replace a measure, a current law source, an event official, a coach or the people responsible for the venue.

Review authority and safety boundaries

Responsible organization

Cambridge Bowling Club Incorporated

Public club and Bowls New Zealand sources identify Cambridge Bowling Club at 37 Thornton Road, Cambridge 3434, under Bowls Waikato. The app support policy is specific to Rink & Radius and is separate from general club operations, membership records, websites and external services.

About the app and publisher

Local by design

The useful work happens on the device.

Rink & Radius version 1.0.0 packages its lessons, illustrations, temporary instruments, source notes and privacy text inside the Android application. It has no Internet permission, account, cloud database, advertising, analytics, attribution or remote configuration. A lesson bookmark or reading preference may remain in app-private storage; an End Composer result, Head Mapper layout, Green Notes strip and Club Day selection are intended only for the running session. Clear Local Choices, Android Clear storage or uninstall removes app-held state.

Authority remains human

An illustration cannot inspect a real green.

The product cannot confirm a session, forecast, surface, access route, equipment, law, condition of play, score, selection, eligibility decision or participant readiness. Current club staff, adult session leaders, coaches, event officials, posted venue instructions, qualified professionals and emergency services take priority. The app supports a calmer conversation; it does not silently turn that conversation into an operational instruction, official record, medical assessment or emergency report.

Publication boundary

A package is not a public deployment.

This static site explains the app and hosts its app-specific policy after deployment. A ZIP stored on a computer is not yet a public privacy URL. The publisher must upload the package, verify the final HTTPS homepage and both privacy routes, confirm control of the published support contact, review current Play declarations against the exact AAB and retain appropriate rights evidence for supplied or generated imagery.
