What Actually Happens When You Delete Your Copilot History via Privacy Settings — I Tested It

Why I Did This

I went looking for clear documentation on what exactly happens when you delete your Copilot history through the Copilot Privacy Settings — specifically, what it means for your scheduled tasks (Copilot Tasks) and any web apps that were created and deployed through those tasks. I couldn't find a straight answer anywhere. Microsoft's support pages cover the basics, but they don't really spell out the downstream effects on tasks and deployed apps.

So I decided to just test it myself and document what happened. Here's what I found.

The Question

I had two specific things I wanted to figure out:

1. If you delete your Copilot history via Copilot Privacy Settings, does it also delete your scheduled tasks (Copilot Tasks)? Or do tasks live separately from conversation history?

2. If the tasks do get deleted, do the web apps that were created and deployed through those tasks still work? In other words, are deployed apps tied to the task lifecycle, or are they independent once they're live?

What I Did

The setup was simple. Before deleting anything, I made sure I had:

Active Copilot conversations with scheduled tasks (Copilot Tasks) attached to them

Web apps that had been built and deployed by Copilot Tasks, with their hosted URLs bookmarked and saved separately

Then I went to Copilot Privacy Settings and hit delete on all history.

After that, I checked what survived and what didn't.

Results

Here's the breakdown:

What Was Tested Result

Conversations All deleted. Every conversation was wiped — no traces left.

Scheduled Tasks (Copilot Tasks) All deleted. Every scheduled task was gone, including any references or links to apps they had created.

Deployed apps (accessed via saved URL) Still accessible and fully functional. Every app I had saved a URL for continued to load and work normally.

Key Takeaway

Deleting your history is a clean sweep. It removes both your conversations and your Copilot Tasks — not just chat history. This is an important distinction. If you're thinking "I'll just clear my chats," be aware that your scheduled tasks go with them.

However, deployed apps survive. Once a web app has been deployed by a Copilot Task, it's hosted independently. The app doesn't care that the task which created it no longer exists. As long as you have the URL, you can still access it.

⚠ Important Tip

If you've built any apps through Copilot Tasks that you want to keep using, save the URLs before deleting your history. Once you delete, the tasks — and any reference to those app links within Copilot — will be gone. If you didn't save the URL somewhere else, you'll have no way to find it again.

Note

This was tested on May 2, 2026. Microsoft updates Copilot frequently, so this behavior may change in future updates. If you're reading this much later, it's worth verifying with a small test of your own before doing a full delete.

Hope This Helps

I know this is a niche scenario, but I figured if I was wondering about it, someone else probably is too. Hopefully this saves you from the uncertainty of not knowing what "delete history" actually touches.

If you've tested similar scenarios — or if you've noticed different behavior on your end — I'd love to hear about it. Drop a comment or reply and let's build out a better picture of how this all works together.
