Frequently asked questions

Is Charcal free?

During the beta, yes, with every feature.

Do I need an account?

No. Without an account Charcal works in full and your tasks stay on your device. You only need an account if you want the same tasks on iPhone, iPad and Mac.

Does it work offline?

Yes. You can type and check off tasks without a connection, and if you have an account, sync resumes by itself when the network is back. Dictation needs the network once, to download the language.

Which languages does it speak?

English and Italian. It starts in your device's language, and you can change it in Settings, General. It reads sentences in the language you choose: "tomorrow at 8 dentist" in English, "domani alle 8 dentista" in Italian.

Which devices does it run on?

iPhone and iPad with iOS 26.1 or later, Mac with macOS 26 or later.

Can I bring in Reminders and Todoist?

Yes, from Settings, Calendars.

Reminders: lists become labels, with day, time, priority and repeats. Nothing changes in Reminders.
Todoist: you need your Todoist token, which stays on the device. Projects become labels. When you check off an imported task in Charcal, it is closed in Todoist too.

In both cases a second import adds only what is missing.

Does it work with Claude, ChatGPT or the terminal?

Yes, with an account. AI assistants connect through MCP and the Mac has a command line: the steps are in AI assistants and command line.

Can I see my tasks in my calendar?

Yes. In Settings, Calendars you can link Apple Calendar. If you have an account you can also add the Charcal calendar address to Google Calendar or Outlook.

How do I export my data?

There is no export in the app today. Write to us and we will send you a copy of your data.

How do I delete my account?

Go to Settings, Account, Delete account and type "delete" to confirm. The server deletes the account and everything in it right away; backups expire within a week. Your tasks stay on the device: if you want those gone as well, uninstall the app.

I forgot my password

On the sign-in screen tap "Forgot password?" and follow the steps. If you cannot get back in, write to us from the account's email address.

If sync stops

Check that the device is online.
Open Settings, Account and tap Sync now.
If a notice at the top of Today says your session has expired, tap Sign in and sign in again. In the meantime your tasks stay on the device and nothing is lost.
If it still does not start, write to us. Knowing what time you noticed is usually enough for us.
