SafeSite – Privacy Policy

Last updated: 10 November 2026

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.

The short version

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.

Why SafeSite can read web pages

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.

What SafeSite keeps on your device

All of this is kept in your browser’s storage for the extension, on your device:

• Your safe sites. In Chrome and Edge, SafeSite can use your browser bookmarks as the list (or only its own SafeSite bookmarks folder, if you choose). In Safari and Firefox for Android, SafeSite keeps its own list.
• Sites you marked as unsafe, and sites or tabs where you turned warnings off.
• A history of warnings: the unsafe sites where SafeSite warned you, with the page addresses and how many times you visited. Entries are removed after 30 days by default; you can change this or clear it in Settings.
• Your settings, including where you dragged the page icon.

Uninstalling SafeSite removes all of this from that device.

Explain and the AI check

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:

• Safari: Apple’s on-device model where Apple Intelligence is available; otherwise Apple’s on-device text recognition with SafeSite’s own rules.
• Chrome and Edge: the browser’s built-in on-device model (Gemini Nano in Chrome, Phi-4-mini in Edge).
• Firefox on a Mac: the SafeSite Mac app, in the same way as Safari.
• On a Mac or PC, if you choose: a model you run yourself on the same computer (Ollama or LM Studio). SafeSite only connects to it on that computer (localhost).

None of these send the page to us.

Syncing between browsers on a Mac

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.

Notifications

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.

Export and import

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.

Network use

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.

Children

SafeSite doesn’t collect information from anyone, including children.

Keeping and deleting your data

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.

Changes

If this policy changes, the new version will be posted here with a new date.
