A customer-support dashboard and a financial portal do not expose the same information. One may show names, email addresses, and ticket histories. The other may show balances, card details, account numbers, and transaction references.
Using one global privacy rule for every website usually creates two problems. It misses business-specific information on important pages and hides harmless content elsewhere.
A stronger approach gives each site a small, understandable privacy policy.
Begin with the purpose of the site
Write down what the presenter needs to show and what the audience does not need.
For a support tool, the audience may need to see the ticket workflow but not the customer identity. For an analytics dashboard, the chart shape may matter while revenue totals and tenant names do not. For a developer console, the route may be useful but tokens, keys, and account IDs must remain covered.
This purpose statement prevents the team from hiding everything or trusting the page by default.
Use common detection as the baseline
Recognizable values should be protected across sites: email addresses, phone numbers, payment numbers, credentials, API keys, tokens, private keys, and other structured secrets.
The baseline handles repeated risks without requiring a separate rule for every page. It should also cover content inserted after the initial page load and values inside inputs when input scanning is enabled.
Site-specific rules should add context to this baseline, not replace it.
Add narrow rules for business identifiers
Internal customer codes, tenant slugs, employee IDs, invoice references, and project names may be sensitive even though they look like ordinary text.
Create custom patterns from the stable part of the identifier: a prefix, separator, character class, or expected length. Test valid examples, near misses, and unrelated text.
Avoid broad rules such as “hide every six-digit number.” They create false positives and encourage presenters to disable protection. A narrow rule is easier to explain, test, and maintain.
Save visual regions that text rules cannot describe
Some sensitive content has no useful text pattern. Avatars, charts, maps, QR codes, balances rendered on a canvas, and customer screenshots need visual cover.
Persistent manual regions are useful when the layout remains stable. Place the region over the specific component and verify it at different window sizes, zoom levels, and responsive breakpoints.
If the page moves the component unpredictably, replace the source data or use a safe screenshot rather than trusting a fixed rectangle.
Decide which sites should start protected
High-risk tools should not depend on someone remembering to turn privacy on before a meeting.
Use per-site controls so dashboards, admin panels, CRM pages, payment portals, and developer consoles open in the intended state. Lower-risk sites can use the common baseline without extra manual regions.
Review subdomains and alternate environments. A rule created for app.example.com may not automatically cover admin.example.com or a staging host.
Test the complete route, not one URL
A site policy can work on the landing page and fail after navigation.
Rehearse search, filtering, record details, modals, dropdowns, input fields, exports, settings, and account switching. Check content loaded after a click and pages opened in new tabs.
Use invented values that resemble the real formats. Confirm that the rule hides the intended content and leaves the task understandable to the audience.
Handle exceptions carefully
A false positive should lead to a narrow exception, not a disabled site policy.
Use a temporary peek when a presenter needs to verify one value. Add an always-show exception only when the value is consistently safe. Document why the exception exists and remove it when the page or demonstration changes.
Keep a panic shortcut ready for an unexpected state. The presenter should be able to darken the page immediately without searching through menus.
Review rules when the product changes
Site policies are part of the demo and screen-sharing workflow. They need maintenance when the product UI changes.
Assign an owner, record the protected pages, and run a short regression check before important meetings. Review after a redesign, a new integration, a changed identifier format, or a browser-extension update.
A useful checklist includes:
- baseline detectors still work;
- custom patterns match current formats;
- manual regions align at common screen sizes;
- inputs and dynamic content remain protected;
- per-site defaults cover every relevant host;
- peeks and exceptions behave as expected;
- the panic shortcut is familiar to the presenter.
Auto Blur performs sensitive-data detection on the device in Chromium browsers. It supports common detectors, input scanning, custom regex rules, persistent manual regions, per-site controls, temporary peeks, automatic protection triggers for supported contexts, and a panic shortcut.
Privacy is easier to maintain when the page remembers its rules and the presenter can focus on the conversation.
