Public chat, NPC dialogue, system messages and battle logs are discarded at the storage layer unless you opt in. Retention windows are configurable per channel, history can be wiped retroactively, and everything can be exported on demand.\n\nFeatures:\n- Channel whitelist with a Privacy-First default\n- Per-channel retention with a daily background sweep\n- Retroactive cleanup with preview and Ctrl+Shift confirm\n- Export to Markdown, JSON or CSV\n- First-run wizard with four profiles: Privacy-First, Casual, Roleplay, Full History\n- Multi-language UI (24 locales) with live language switching\n- Own config and database — no shared state with other plugins\n\nBased on Chat 2 by Infi and Anna (EUPL-1.2).\nSupport: https://discord.gg/X9V7Kcv5gR",
