Public data: posts, replies, media metadata, reports metadata, board activity, and moderation outcomes can be visible or reviewable by moderators.

Wallet auth: Solchan uses signed messages to verify wallet control. We store session/auth records and board-local anonymous identities derived server-side.

Rate limits: anti-spam counters use hashed subjects. The app should not store raw IP addresses in rate-limit rows.

Media: uploaded media/content may be moderated. Do not upload private, sensitive, or illegal material.

Deletion: moderation may tombstone content instead of fully deleting it to preserve thread continuity and auditability.

Launch note: replace this placeholder with final retention, processor, contact, and jurisdiction language.
