Your story in the palm of your hand
Ourcana ("Our Arcana") is a Plural System tracker app for managing a collection of members (which can be alters, original characters, personalities, etc).
It lives on your device, end-to-end encrypted, and syncs everywhere you go. No server owns your data. No one can lock you out.
Track your system members, which of them are fronting (if any, or even all of them!), and use markdown to log journals, design rich profiles (with formatting, style elements, and inline media) and track relationships and interactions between all your system's members.
Runs on iOS, Android, macOS, Windows, Linux, and right here in your browser -- no install required!
Fully encrypted, so you choose what you share
As a journal and personal tracking app, Ourcana keeps all your data private, personal, and offline-first by design. Journals and chats are only stored on the device itself by default, and the sync settings allow one to choose which other data (if any) to share with PluralKit or Ourcana's Online servers.
Lives on your device
Your members, fronts, and journals are stored on your own devices. There's no central server holding your system unless you add one... all data is only ever decrypted and/or shared directly by you.
End-to-end encrypted
Anything that does leave your device is encrypted with a key only you hold. Save remote backups with confidence that even the developers can't read it. Share data with buckets and fine-grained permissions.
Yours to keep, forever
Export everything in one tap, anytime. No lock-in, no hostage data. If you ever leave, you take your whole story with you. OpenPlural-compatible export coming soon! Sync with other services as the dev team integrates with them.
Reach friends with confidence
Any friends you share data with get an unlock key in a private exchange you both approve, and access can be revoked or set private again all you need. Servers act as encrypted relays that only know you own a given piece of data with no idea what's inside.
A home that speaks your language
Ourcana's design and UX allude to classic card decks, fantasy fortune-telling, and medieval alchemy and magic with the Tarot and its Major Arcana cards as a for-fun, lighthearted theme to manage character, system, member, and group data.
Terminology is yours to set. One can change all the terms inside the app however they'd like in settings such as deck, member, system, fronting, etc.
A deck for your system
Every member is represented with a card. Markdown profiles with embedded images, unlimted custom fields, and a tarot-inspired deck with a space to make your own.
Cards for members all to themselves
Start composing rich profiles and connections between your members to track at a glance.
Edit in markdown to customize each member
Edit in your favorite markdown flavors, compose tich images and media inline with document formatting, add custom art for your members, or integrate with PluralKit like the dashboard!
Track long-term history at a glance
Splits, merges, co-fronting, Ourcana tracks the shape of your fronting over time and rebuilds the full picture, merging in data you track manually on watch, phone, or desktop and across other apps you may track data with through integrations.
Front history that tells the whole story
Fine-grained editor controls allow you to zoom in, out, and scroll all through your your records to always know the full story.
Confer as a group and reach consensus
In-system chats called Spaces let each member speak for themselves and allow for rich interactions with images, links, GIFs, and more! Friend to friend chats coming soon with online support.
Track lore that's all your own
A rich markdown editor with support for tables, inline styles, and more lets you express yourself and track your inner system narrative in a private text editor with rich Markdown notes using standard text conventions.
Navigate your system structurally
Ourcana's tag tree view allows for deeply-nested filters that group members by topic or association. Customize to your heart's content!
Categorize flexibly
Tags allow one to put members into categories with optional nesting and sub-system structures with ease.
Record every detail
Tags group members along the hierarchy and can be used for searching and filtering to quickly access sub-systems and side-systems within your system data. Edit their icon, description, color pallete, and more!
Bring everything. Lose nothing.
Coming from another app? Ourcana imports it all and remembers exactly where each piece came from, so nothing gets flattened or forgotten.
Import without losing the source
Pull in members and front history from PluralKit, PluralSpace, SimplyPlural, and Florality at once. Ourcana keeps track of which app each fact came from, so it can rebuild the displays and metrics of all of them.
Sync without a master server
Edits made offline on different devices merge cleanly when they reconnect. No central referee, no lost changes, no overwriting each other.
Everywhere you are
One system, every device. Phone on the bus, laptop at home, watch on your wrist... all the same data, all in sync, all yours.
Free where it counts. Paid only where it's kind.
The app is free on every platform, forever. Paid extras are for the convenience of letting us host a sync server for you automatically. The sync server is free to download and run so you can always run it yourself for nothing or if Ourcana Online shuts down.
