If a person joins the complimentary founding pilot, the service may store the invitation status, onboarding checklist, learning goal, and feedback that person submits. Membership entitlements and billing references are server records when those systems are active. A final server-record retention schedule has not been published; paid enrollment remains disabled while deletion and retention procedures are being verified.
If Community Memory is enabled, its server records may include a board reference, plain-text comments and replies, withdrawal state, private reports, account blocks, weekly idea editions, contribution credits, and deletion requests. Recent comments are displayed only within the 30-day discussion window. A published weekly edition is a separate, longer-lived record of reviewed ideas and changes; it is not a live consensus score. Community Memory writes are disabled until the hosted data, moderation, publishing, and deletion procedures are verified.
