How can we help?

Getting started

What is Lumen Planner?

Lumen is a weekly planner. You put tasks on days, not in an endless list. Each week starts on the day you choose, and anything you did not finish moves to the next week on Sunday night, unless you tell it not to.

Setting up your first week

1. Open Lumen and pick the day your week starts. Monday is the default.
2. Add three to five tasks to today. Keep them small enough to finish.
3. Drag a task to another day to move it. Long-press on a phone.
4. Tap the circle to mark it done. Done tasks stay visible, greyed, until the week rolls over.

Recurring tasks

Type a task and add every monday, every weekday or every 2 weeks at the end. Lumen understands those three forms only. Editing one occurrence changes only that one; editing from the task's menu changes the series.

Syncing

Which devices sync?

iPhone, Android and the web app sync through your Lumen account. There is no desktop app; the web app at the same address works on a laptop.

Does it work offline?

Yes on the phone apps. Changes you make offline are kept on the device and sent when you are back online. The web app needs a connection to load, then keeps working for the current week if the connection drops.

I changed phone and my tasks are gone

They are not gone. Sign in with the same email on the new phone and the weeks come back. If you used the app without an account on the old phone, the tasks lived only there: open the old phone, go to Settings, Create account, and the tasks are uploaded.

How often does it sync?

Every change syncs immediately when online. If two devices edit the same task within a few seconds, the last edit wins; nothing is merged.

Sharing

Can I share a week with my partner?

Yes. Open the week, tap Share, enter their email. They see the whole week and can add, move and complete tasks. Shared weeks have a small two-dot badge. Sharing is per week; a new week is private until you share it too.

Can I share a single list?

Lumen does not have standalone lists. The closest is sharing a week with only the tasks you want in it. People often keep a "Household" week for this.

Who can see my tasks?

Only you, and the people you shared a specific week with. Lumen staff cannot read task text; it is stored encrypted and decrypted on your devices.

Removing someone

Open the shared week, tap Share, tap the person, Remove. They lose access immediately and keep nothing.

Billing

Plans

How do I cancel?

Settings, Plan, Cancel. You keep Plus until the end of the period you paid for, then the account goes back to Free with all tasks intact. Shared weeks stop being shared at that point.

Invoices and receipts

Every payment emails a receipt. For a PDF invoice with a company name, open Settings, Plan, Invoices, and add the details once; past invoices are regenerated.

Refunds

Yearly plans can be refunded within 14 days of payment, from Settings, Plan, Request refund. Monthly plans are not refunded; cancel instead and the month runs out.

Troubleshooting

A task shows twice

Usually a recurring task edited on two devices while one was offline. Delete one copy; the series is unaffected.

Notifications do not arrive

On iPhone: Settings, Notifications, Lumen, Allow. On Android, also check that battery optimisation is off for Lumen. Then open Lumen, Settings, Reminders, and send a test reminder.

The week rolled over and I lost my unfinished tasks

They moved to the new week, at the top, marked with an arrow. If you turned off "Carry over unfinished tasks" in Settings, they stay in the old week; swipe left to see it.

The app is slow

Lumen keeps two years of history on the device on Plus. Settings, Storage, Keep only this year, frees most of it. History stays in your account.
