Python script to delete completed tasks from your Todoist Inbox

todoist-cleaner.py

import todoist

api = todoist.TodoistAPI(token='<your_token_here')

# Initial sync of your account
api.sync()

# Find Inbox in project - can be adapted to delete completed tasks for other projects as well
projects = api.projects.all()
inbox = next(p for p in projects if 'inbox_project' in p)

# Process tasks until explicitly aborted
while True:
    # Get completed tasks for project, a maximum of 100 tasks is supported per batch
    completed = api.items.get_completed(project_id=inbox['id'], limit=100)
    if not completed:
        break  # No completed tasks left, abort

    # Delete the completed tasks
    for c in completed:
        api.items.delete(c['id'])

    # Commit deletion requests
    api.commit()

Maybe we can change the content before deleting, but I imagine that is also stored in the activity log. At this point then, we need a different more private to-do app, perhaps one with end-to-end encryption on the content of tasks. Only end-to-end encrypted to-do app I know of is Lunatask https://lunatask.app/ and note-taking apps like Joplin, but Lunatask isn't fully supported on mobile yet.
