Safety
Can it break my PC?
It can make mistakes, because AI suggestions can be wrong. That's why anything that changes your PC waits for your approval, and why it tries to make a Windows restore point first. Read each step before you approve. See What it can change, and how you approve it.
Can it do things I didn't approve?
It's designed not to. Read-only checks run on their own, but anything that changes your PC waits for your approval, and some actions, such as reading saved passwords, are blocked even if you approve.
How do I undo a change?
Through Windows System Restore, using the restore point it made. See Backups and restore points.
Cost
How much does a diagnosis cost?
Most use a fraction of a credit. Each one has a limit, and Diagnosly asks before it spends more. See How credits work.
Is it a subscription?
No. Nothing renews. You buy credits when you want them.
What if it fails?
A diagnosis that fails or times out because of us isn't charged in full. See Spending limits and checkpoints.
Can I get a refund?
Credits you've used are not normally refundable, apart from failed diagnoses. Unused credits may be refundable at our discretion. See the terms, or email support@diagnosly.app.
What it can do
What does it work on?
Windows 10 and 11. There is no Mac, Linux or phone version, and one account covers one PC.
Can I use it on more than one PC?
Not on one account. An account is tied to one PC. If you replace your PC, open the app on the new one and use Reconnect this PC, or email us if the name differs.
Does it fix everything?
No. It can say "I could not fix this one" and then tells you plainly what's left to try. See Follow-ups.
Which AI model does it use?
You choose a Mode (Quick, Auto or Max). Diagnosly looks after the model for you.
Privacy
What does it send?
Only what it needs, cleaned of personal details on your PC first. See Privacy basics.
Does it train AI on my data?
We don't use your telemetry or diagnosis data to train shared AI models.
How do I delete my account?
Email privacy@diagnosly.app. See Your data and deleting your account.
The app
Why does Windows warn me about the installer?
It isn't code-signed yet. See Installing the app.
Does it run all the time?
The background service runs on your PC so it's ready when you diagnose. Closing the app window hides it to the tray. Start with Windows is off by default.
How do I update it?
It updates itself. See App updates.
Still stuck?
See Troubleshooting or email support@diagnosly.app.
