FAQ

Getting Started

How do I add a task?

Tap the chat button and type something like "pick up groceries tomorrow" or "finish report by Friday at 3pm." Cassiel will create the task, figure out the due date, and slot it into your list.

How do I edit a task?

Tap any task in the list to open the editor. You can change the text, due date, time, or mark it as starred. You can also tell the chat "change my groceries task to Thursday" and it'll update it.

How do I complete a task?

Tap the checkbox next to it. Completed tasks move to your archive automatically.

How do I delete a task?

Open the task editor and tap Delete. Or tell the chat "delete my groceries task."

Big Goals

What are Big Goals?

Big Goals are the larger objectives you're working toward โ€” things like "Launch the side project" or "Get in shape for summer." Tasks can be tagged to a goal so you can see progress at a glance.

How do I create a Big Goal?

Go to the Goals tab and tap the + button. Give it a name and an emoji.

How do tasks get assigned to goals?

Cassiel automatically suggests a goal for new tasks based on context. You can also assign one manually in the task editor, or tell the chat "tag my report task to Q2 planning."

Chat

What can I ask Cassiel?

Anything about your tasks, goals, and what you should be focusing on. Examples: "What's on my plate today?" ยท "Add three tasks for the weekend: mow lawn, clean garage, fix the fence" ยท "Move everything due this week to next Monday" ยท "What am I behind on?" ยท "Plan my day" ยท "What am I not working on that I should be thinking of?" ยท "What's stopping me from reaching my goals?" ยท "Change the filter on the third Monday of every month"

How is Cassiel different from a task list app?

Most task apps help you track what's due today. Cassiel takes a mentor's view โ€” it looks at your goals, the work you have planned, the work you've done, and most importantly the things you're not working on. It helps you build a real path to reach your big life goals, not just check off daily tasks. The chat and Home Screen will coach you proactively, or you can talk to them โ€” as you would talk to the angel of time, who doesn't judge and is only there to help you, patiently, day after day.

Does Cassiel remember things about me?

Yes. Cassiel picks up facts from your conversations โ€” your name, where you live, preferences, routines โ€” and uses them to give better answers over time. You can view and edit these in Settings โ†’ Facts.

Alerts & Reminders

How do alerts work?

When you create a task with a due date and time, Cassiel sets a reminder automatically. You'll get a notification before it's due.

How do I set a recurring task?

Just describe the schedule in plain English โ€” "change the filter on the third Monday of every month" or "water the plants every Wednesday." Cassiel handles the repeat automatically.

How do I set a daily reminder?

Go to Settings โ†’ Daily Reminder and pick the time you'd like a nudge. You can set separate times for weekdays and weekends.

How do I dismiss an alert?

Tap the alert in the task list and dismiss it. It won't come back for that occurrence.

Account & Data

Where is my data stored?

Securely in the cloud under your account. No one else can see it.

How do I delete my data?

Settings โ†’ Delete All My Data removes everything permanently โ€” tasks, goals, chat history, and archive.

How do I delete my account?

Settings โ†’ Delete Account. This removes all your data and your login credentials.

Is my data shared with anyone?

No. We don't sell your data, don't show ads, and don't share anything with third parties.

Privacy

What permissions does Cassiel need?

Only notifications (optional, for alerts and daily reminders). Cassiel doesn't ask for access to your location, camera, contacts, or anything else.

Does Cassiel work offline?

Yes. You can add, edit, complete, and delete tasks offline โ€” all changes are saved locally. You just need internet for AI features like chat, analysis, and clarifications. Once you reconnect, everything syncs to the cloud and appears on your other devices.
