What leaves your computer. Almost nothing.
Reported is built so the checking happens on your own machine. This page lists every case where something is read, sent or kept, in plain words.
Tool by tool
| Tool | What it reads | What is sent | What is kept |
|---|---|---|---|
| PC checkup | Antivirus status, installed programs, startup items, recurring tasks, browser add-ons and notification permissions, account names, a few security settings. | Nothing. | One results file on your own Desktop. We never receive it unless you send it to us. |
| Message checker | The email or text message you paste. | Nothing. It is read inside your browser. | Nothing. |
| Password check | The password you type. | Not the password. It is scrambled in your browser and only the first five characters of the scrambled version go to Have I Been Pwned, which returns possible matches for your browser to compare. | Nothing by us. |
| Email breach search | The email address you type. | The address goes through our server to Have I Been Pwned to be looked up. | We do not store the address. To limit abuse we briefly keep a scrambled, non-reversible fingerprint of your network address and the times of recent searches. |
| Message form | Your email address and the message you write. | Both, to our server, so a person can answer. | The message and your address, in a private file on our server, until it is dealt with or you ask us to delete it. |
| Checklists | Which boxes you tick. | Nothing. | Your ticks, in your own browser's storage on your device. |
