SafeSite is a browser extension for Safari (iPhone, iPad and Mac), Chrome, Microsoft Edge and Firefox, with a companion app for iPhone, iPad and Mac. It is made by Athelstan Services Ltd, which is responsible for it under UK data protection law.
SafeSite does not collect, sell or share any personal information. We never see the sites you visit or anything you type. There are no accounts, no ads, no analytics, no tracking and no third-party code that collects data.
To warn you in time, SafeSite needs permission to read every website you visit. On each page it looks, on your device, for password, payment and similar fields, and compares the site with your list of safe sites. It never reads or stores what you type into those fields, and it never sends pages, addresses or anything else from them to us or anyone else.
All of this is kept in your browser’s storage for the extension, on your device:
Uninstalling SafeSite removes all of this from that device.
Explain can take a picture of the page you’re looking at to show why it was flagged. The picture stays on your device.
The AI check is optional. When you turn it on, the page’s text or a picture of it is checked by a model on your device:
localhost).None of these send the page to us.
If you turn on Sync with other browsers, Safari, Chrome, Edge and Firefox on the same Mac share your safe sites through a file kept by the SafeSite app on that Mac. It is never sent off the Mac.
SafeSite’s warnings can appear as notifications. They are created on your device by the SafeSite app or your browser, and are not sent through any server of ours.
When you export your safe sites, SafeSite saves the file only where you choose. When you import a file, it is read on your device.
The only thing SafeSite downloads is the Public Suffix List from publicsuffix.org, which helps it tell where one website ends and another begins (for example that www.example.co.uk and example.co.uk are the same site). No information about you or the sites you visit is sent with that request.
SafeSite doesn’t collect information from anyone, including children.
Your data stays on your device until you delete it in SafeSite’s Settings or uninstall SafeSite. Because we hold no data about you, there is nothing for us to access, correct or delete on our side, but you’re welcome to contact us with any question.
If this policy changes, the new version will be posted here with a new date.
