Safe Privacy Mask
Before sending text to AI
Replace email addresses and configured terms in the input field before sending. Review the result: some information may be missed.

A small check in your work browser.
Legacy Tools are Chrome extensions that help you check for things you might overlook at work, before sending text to AI, opening an email link or uploading a file.
Decide for yourselves whether these tools fit your workplace. Review their uses, data handling and limits before trying them with a small group.

WHERE IT HELPS
Start with one task
Start with one situation your team encounters regularly. Each card explains which tool can help and what its limits are.
Safe Mail Link Check
Before opening an email link
Compare the displayed text with the destination in Gmail, Outlook on the web, Yahoo! Mail and other supported sites. It does not judge whether the destination is safe.
See Safe Mail Link Check →Safe Attachment Check
Before uploading a file
View metadata such as location or author in supported file formats. It does not remove metadata, edit the file or block the upload.
See Safe Attachment Check →Safe Privacy Gate
Before submitting information to a website
Prompt for a check when text or a filename matches detection rules. It does not rewrite the text or enforce a ban on sending.
See Safe Privacy Gate →EVALUATION CHECKLIST
What to check before you adopt it
These checks cover the public Chrome Web Store editions. Transparency contains the per-product permissions and steps to inspect network traffic.
- Where processing happens
- The public extensions introduced here detect, replace or inspect files inside the browser. They do not send input or detection results to the developer’s servers.
- Network traffic and usage collection
- The public extensions themselves do not send data to external APIs or collect analytics or telemetry. This is separate from requests made by websites you use. The Legacy Tools website uses Google Analytics.
- Storage and sync
- Gate, Mask, Mail Link Check and Attachment Check store settings; Mask also stores rules and target sites. Other products may store collected text or registered people’s information. Safe Night Check settings may sync to other devices through Chrome.
- Chrome permissions and site access
- Permissions differ by product. Gate requests access to all sites; Mask uses storage, scripting and optional access for added sites. An extension can load on all sites without declaring host_permissions, so check both API permissions and where it runs.
- Accounts
- The public extensions are free and require no Legacy Tools account or login. Accounts for the AI or email services you use are separate.
- Known limits
- Supported sites, input fields and file formats are limited, and detection can miss information or flag it incorrectly. Review each product’s scope and test it on the screens your team uses.
- Management, audit and support
- The public extensions have no admin console, central management, audit log, SLA or organizational support contract. For organization-wide settings distribution and locking, see the management option below.
PUBLIC EDITIONS
Try the public editions with a small group
You can try the public Chrome Web Store editions with a small group. Check how they are installed and supported before you begin.
What they let you do
Each person adds the extension from the Chrome Web Store and configures it themselves. After checking your internal rules, limit the trial to one task and a small group.
What they assume
Public-edition questions go to the shared support desk. These editions do not meet rollout requirements that depend on organization-wide management or contractual response guarantees.
HOW TO PILOT
Try small, then decide whether to continue
Use these five steps to try the tools with a small group before considering a wider rollout.
- Choose one task
- Try with a few people using samples without confidential information
- Check permissions, data handling and usability
- Assess fit with your rules, including missed and incorrect detections
- Consider managed features if you need consistent settings
Record the product, version, sites, settings, benefits and problems so your team can decide whether to continue.
MANAGED OPTION
When you need managed settings
Safe Privacy Mask Enterprise is a separate, privately distributed product with administrator-distributed rules, settings locks and audit logs. Compare it on the product page if the public edition is not enough.
| Aspect | Public editions (free) | Safe Privacy Mask Enterprise |
|---|---|---|
| Who sets the rules and settings | The person using it | The administrator (users can be locked out of editing) |
| How it is delivered | Each user adds it from the Chrome Web Store | A privately distributed CRX, delivered by GPO, MDM or the Admin Console |
| Settings distributed and locked | None | Yes — distributed and locked by managed policy |
| Audit log | None | Yes — no message text recorded, forwarding to your own collector available |
| Traffic leaving the machine | None from the extension itself | Only with the optional second check enabled, to the endpoint your organisation configures |
| Terms and support | Free, one shared support form | Quoted, with rollout support |
Safe Privacy Mask is the only product with a managed edition. The others have no administrator-distributed build.
There is no vendor-hosted admin console. Optional secondary checks send locally masked text to your configured endpoint; audit logs can also be forwarded. Review permissions and traffic separately from the public edition.
See Enterprise differences and limits →LIMITS
Limits and what is not guaranteed
Check these limits before deciding whether to use the tools.
- These tools do not completely prevent data leaks or fraud, or reliably identify every danger.
- They do not replace existing DLP, access controls or approval procedures.
- A prompt or replacement does not decide whether you should send the information or open the link. People still need to check and decide.
