# Schedule Mastodon posts from your Mac

Clacky’s Calendar, in the Dashboard, plans and schedules Mastodon posts from your Mac. Write a post once, see if it fits Mastodon’s limit, and drop it on a day.

## How to connect Mastodon

Give your server (like mastodon.social) and an access token. On your server: Preferences → Development → New application. Tick write:statuses and write:media, save, then copy “Your access token”.

In the Clacky window, pick Dashboard, then Calendar. Accounts is on the right: click Connect an account and pick Mastodon. Clacky checks the details with Mastodon when you connect.

## Write once, schedule, move

Click New post and write it once. A post to Mastodon can be up to 500 characters. If a post is too long for one of the platforms you picked, Clacky says so, and Tailor per platform gives Mastodon its own text.

Choose a time and click Schedule, or Add to queue to use the next free best time (★ days come from your own posts’ engagement, or common good times until you have some). Drag a post to another day, edit it or cancel it, with Undo for a few seconds. Post now asks once more before anything goes live.

## See which posts sent visitors

Links to your own websites get a tag for each post when it’s scheduled, so the Calendar’s Stats and Clacky’s Analytics show which posts sent visitors and sales.

## Questions

Does it work with any Mastodon server?

You type your own server’s address when you connect, together with an access token made on that server.

Does Clacky ever post without asking?

No. It sends a post only at the time you scheduled, or when you click Post now and confirm.

Where are my drafts kept?

Drafts and the queue are kept on your Mac. Scheduled posts go to Clacky’s posting service so they can go out on time.
