Plural Star is a private, offline-first system management app built for plural individuals, those with DID, OSDD, or any form of plurality. Made in part with AI assistance, which is one of the main reasons we went Open Source. So that anyone wishing to, or with concerns, can examine the code. Simply Plural and Octocon have been discontinued. Plural Star is the replacement you own entirely; your data stays on your device. Features Three-Tier Front Tracking Track Primary Front, Co-Front, and Co-Conscious. Each tier has its own member, mood, note, and energy (1–10); Primary also tracks location. Members are exclusive to one tier. A persistent notification keeps all tiers visible. Optional front-check reminders. Friends & Syncing Optional end-to-end encrypted networking, off by default; the relay sees only encrypted blobs. Add friends with short mutual codes and see their front live. Privacy Buckets set what each friend sees: members, groups, journal, history, profile, whiteboard, or planner. Link your own devices: pick which sends first, then everything syncs both ways, pictures included. Pin up to five friends into the notification, or the iOS Live Island. Member Profiles Profile pictures, 900×300 banners, names, pronouns, roles, colors, rich-text bios with full Markdown. Freeform tags and colored groups with multi-group membership. Facets and Custom Fronts for parts that aren't members. Filter, search, sort six ways. Tier badges when fronting. Archive dormant members: history preserved, restorable. Your Words Rename Headmate, Front, Facet, and more. The whole app follows your system's language. Observatory Mode Turns Plural Star into a manual status tracker and journaling app with a rebuilt UI for the Singlets in our lives, granting almost every feature. For non-plural friends, family, and caretakers. Day Planner Calendar of appointments and repeating reminders, each with its own mark color and alerts. Whiteboard Freeform canvas: pen, shapes, fill, and eraser. Custom Fields Define your own per-member fields, eight types from text to Markdown. Reorderable, renameable, exportable. Mailbox System-wide mail between headmates: per-member inboxes with unread badges, replies, and pinning. Syncs across devices. System Polls Polls the whole system can vote on. Vote tallies, voter tracking, optional closure. One vote per member; changeable until closed. System Map Chart relationships between headmates on an interactive force-directed graph. Members join as you create relationships. History & Insights Front History: timestamped log of every switch by day, with co-front and co-conscious tiers inline. Member History: every session, mood/location/note change, energy, and journal entry per headmate, with totals. Add retroactive entries with three-tier support and overlap detection. System Statistics Total fronting time, session and message counts, with time-range filtering. Leaderboards for fronters, co-fronters, co-conscious, chatters, moods, and locations. Peak Hours shows when your system is most active. System Chat Local-only IRC-style chat, up to 100 channels. Speaker is independent of who's fronting; chat doesn't affect front or history. Text, images, replies, emoji reactions. Archive channels to free storage. System Journal The same rich-text entries with full Markdown as member profiles. Tag by author and topic hashtag. Optionally lock individual entries or the whole journal with passwords. Import & Export Import full system data from Simply Plural, PluralKit, Octocon, Ampersand, Ourcana, HiveMind, Tupperbox, Parallax, PluralLog & PluralSpace. Export as .zip, HTML, or email summary with per-category toggles. Import .txt, .md, or .json directly as journal entries. Multilingual 24 languages: English, Español, Français, Deutsch, Português, Suomi, Norsk, Italiano, Türkçe, Bahasa Melayu, Tiếng Việt, ไทย, 简体中文, 繁體中文, 日本語, Русский, Українська, Nederlands, Íslenska, हिन्दी, Afrikaans, 한국어, Svenska, Polski.
