What crosses the line

Your content stays where it already is.

On the desktop, detection, replacement and restoration happen on your own computer. Your documents, images and original values are never sent to our servers.

Read the technical details

Your device

• Your documents
• The app doing the work
• The list for putting details back
• What it found

Only this goes out

Account and licence checks, signed updates and model downloads. Optional diagnostics exclude your content.

Individual: processing stays on your device. Enterprise: processing stays within your organisation’s infrastructure. Neither sends your content to us.

Feedback rewards

14days added to your plan

Find a miss. Get two weeks on us.

Help us improve detection. Send a safely redacted example of something the app missed. Every new case we confirm earns two weeks of subscription time.

Send an example

01

Take your own details out first

Swap every real name and number for a made-up one. Never send us real personal data.

02

Send us the wording

Paste the text that came out badly, keeping the wording that caused it.

03

Two weeks, once we confirm it

If it is a genuine miss we have not seen before, we add 14 days to your plan.

Open to anyone on a paid plan. One reward per confirmed example. Sending the same text again with different fake names does not count.

Frequently asked questions

The questions people actually ask.

Do my documents leave my computer?

In the Individual edition, processing stays on your device. Enterprise can process content on infrastructure operated by your organisation. Neither edition sends your content to us.

Which third-party tools can I use?

You can copy the reviewed text into any tool that accepts it: email, support platforms, collaboration software or AI assistants. Live browser alerts work on supported websites; selected-text anonymization is available on any page.

Can I restore the original values?

Yes, within the active session. The replacement map stays in local memory and is discarded when the session ends.

Will it catch every sensitive detail?

Detection is best-effort. Review the output and risk report before sharing, especially when context could still identify a person. Anonymization is not guaranteed.

Privacy that stays on your device

Work with any tool. Share less sensitive data.
