Privacy Policy – Personal Web Sentry -

Personal Web Sentry. Last updated October 15, 2026.

This policy describes the Personal Web Sentry Chrome extension, offered by Emjay Design Lab. It applies to the extension running in your Chrome profile.

The short version

Personal Web Sentry keeps its lists, bookmarks, browsing, and a home quote on this computer. It has no account. It does not send those to Emjay Design Lab. It does not sell information. It does not show ads. If someone sets a U.S. town or ZIP code for the weather line on Settings, that place’s latitude and longitude are sent to the National Weather Service. The town name and ZIP code stay on this computer. The home screen also loads the sky pictures for the current conditions, the next hours, and the days from the National Weather Service. A picture address names the sky, such as sun or rain. It does not name the town. That reply includes today’s sunrise and sunset. After sunset, the next sunrise is calculated on this computer from the saved place and is not sent. If someone saves a calendar address on Settings, the home screen asks that calendar for today’s plans and shows the time and the title. The address stays on this computer. The plans are not saved. The background pictures ship with the extension.

What the extension is for

Personal Web Sentry gives an older adult a home screen. The greeting and Settings sit on a picture. Quote, Date & Time, Today, Weather, and Bookmark Favorites are separate panels. The other bookmarks are listed in Chrome’s side panel. An admin, using the PIN-locked Admin Console on the same computer, chooses which sites open quietly, which sites never open, and what happens when a new site is opened. The picture, the quote, the weather, and the calendar address are changed on Settings, which does not ask for the PIN. Chrome’s own Safe Browsing still runs. This extension does not replace it.

Information stored on this computer

The extension saves these items in Chrome’s local storage for this profile:

Approved site names and blocked site names. The same site is not kept on both lists. If a name being added overlaps the other list, including a parent name or a subdomain, the admin is asked first. Choosing to add removes the overlapping name from the other list. Choosing not to add leaves both lists as they are.
Home-screen bookmarks: a name and a web address. Adding a bookmark also saves its site name with the approved sites, unless that site is blocked. Removing a bookmark leaves that site on the approved list. Also which bookmarks are favorites, which built-in category a bookmark is in, the bookmark size, the display theme, and the order of the home panels. The display theme sets the colors and which background picture is used. Those pictures ship with the extension and are not uploaded. Bookmark Favorites on the home screen lists the starred bookmarks. The other bookmarks are listed in Chrome’s side panel. Each tile also shows the site icon Chrome keeps for the bookmarks bar. That icon is not uploaded.
The protection choice: warn on new sites, or only approved sites.
An activity list of up to 100 recent events. An event is a warning, a block, a page opened from the warning, a request for the admin to approve a site, or a scam phrase on a mail screen. A mail event records the mail site and the kind of phrase. It does not record the message. Each other event can include the full web address and the time. A visit to a site that is already approved is not added to this list. The admin can clear the list.
Approval requests waiting for the admin, up to 50. Each one includes the site address and the time.
The admin PIN, saved as a salted hash. The PIN itself is not saved as readable text. The hash only lets the console check the PIN. It does not encrypt the other lists.
The weather place, when someone has set a U.S. town or ZIP code on Settings, and the latest temperature, wind, humidity, the current condition and its picture address, the next 6 hours with a short condition and a picture address for each hour, the next seven days with a picture address for each day, today’s sunrise and sunset, and active weather alerts for that place. An alert keeps its name, when it ends, and a short instruction. The full alert text is not kept.
A home quote typed on Settings, and an optional name of who said it. Leaving the line blank removes it.
A calendar address, when someone has saved one on Settings. Today’s plans are shown on the home screen and are not saved with the other lists.

Opening one page from the warning is remembered only while that page is starting, and then dropped. Until you close Chrome, the extension also remembers the latest warning details for an open tab. Those details are dropped when Chrome closes.

Web addresses

When a page starts to open, the extension looks at that address on this computer. It uses the address to allow an approved site, warn on a new site, or stop a blocked site. The address of an approved visit is not written into the activity list. The address of a warning, a block, a temporary open, or an approval request can be written into the lists above. An address can contain words from a search or a link.

Words on a page

On ordinary http and https pages, the extension reads a portion of the visible words. It looks only for a few specific scam phrases, such as a locked-computer warning, a fake tech-support phone number, a gift-card payment demand, or a push to install remote-access software. On a mail website it also looks for a few mail phrases, such as gift cards for a family member, a demand to read gift card codes aloud, or a bank or government notice pushing an immediate call. The check happens on this computer. The page text is not saved and is not sent to Emjay Design Lab. If a phrase matches, a note covers that page. The page underneath cannot be used, and the note stays until you leave. On a mail website the check runs again when a message is opened. If that message links to a site that is not approved, a bar names the site and can be hidden. The message and the full link are not saved.

When the admin leaves the Home button on, those pages show it in the bottom-left corner. Choosing it opens the home screen in this tab. Nothing is sent. Turning it off in the Admin Console removes the button.

The extension does not read what you type into a box, such as a password. It does not collect form entries.

Chrome bookmarks

Chrome bookmarks are read only when the admin clicks Import Chrome Bookmarks. The extension then lists websites from this Chrome profile so the admin can pick some for the home screen. It does not change Chrome’s own bookmarks. The chosen names and addresses are saved with the other home-screen bookmarks on this computer. The site name is also saved on the approved-site list, unless that site is already blocked. They are not uploaded. Starred bookmarks are listed on the home screen. The others are listed in Chrome’s side panel. Opening that panel does not send them.

Weather

The home screen can show the weather for one U.S. city, town, or ZIP code. Someone types that place on Settings. Settings opens from the shield icon and does not ask for the PIN. The extension matches a city or town on this computer to a place list from the U.S. Census Bureau, and a ZIP code to a Census ZIP code area. It then sends that place’s latitude and longitude to the National Weather Service at api.weather.gov for the current temperature, the wind, the humidity, the next 6 hours with a short condition for each hour, the next seven days, and active weather alerts for that spot. The town name and ZIP code are not sent. The current conditions, each hour, and each day in that reply include a picture address. When the home screen shows the forecast, it loads that picture from api.weather.gov. The picture address names the sky and does not include the town name or the coordinates. The same reply includes today’s sunrise and sunset. After sunset, the home screen calculates the next sunrise on this computer from the saved place. That calculation is not sent. That reply is saved on this computer and reused for a while, so the home screen does not ask for the forecast on every visit. The pictures load again when that forecast is shown. The extension does not read the computer’s location. If the location is left blank, the weather panel stays and no weather request is made. If the National Weather Service does not answer, the panel says the weather could not be loaded. The forecast is data from the National Weather Service. Showing it is not an endorsement by the National Weather Service.

Calendar

Settings can hold one secret iCal address. Google Calendar calls this Secret address in iCal format. Settings does not ask for the PIN. The address stays on this computer. When the home screen opens, the extension asks that address for the calendar. The calendar’s own server receives that request. The file can contain more than today’s plans. The home screen shows the time and the title. It does not add, change, or save those plans. Leaving the address blank and saving stops the request. The Today panel stays and asks for a calendar. If the calendar does not answer, the home screen says the calendar could not be opened.

Home quote

Settings can hold one short line for the home screen, and an optional name of who said it. Settings does not ask for the PIN. Both stay on this computer. Nothing is sent. Leaving the line blank and saving removes the quote.

What this extension does not do

It does not ask you to create a Personal Web Sentry account.
It does not include advertising or analytics.
It does not download a threat list.
It does not ask Chrome for this computer’s location.
It does not sell or rent information. It does not send your lists, bookmarks, PIN, or browsing to Emjay Design Lab.
It does not use the information for any purpose other than the home screen, the home quote, the calendar on the home screen, the weather line, the admin lists, the warning, and the scam note described above.

Chrome and the sites you open

Chrome, Google Safe Browsing, and each website you open have their own policies. Personal Web Sentry does not control them. A website you open can still receive the visit the way it would in Chrome without this extension.

Who can see the stored information

The lists stay in this Chrome profile. Anyone who can use that profile and knows how to open Chrome’s extension storage can read them. The PIN locks the Admin Console only. It does not stop someone from turning the extension off at chrome://extensions. Settings, where the picture, the quote, the weather, and the calendar address are changed, does not ask for the PIN. On a shared computer, a separate Chrome profile for the older adult is the practical boundary.

How long it stays

Settings, bookmarks, and site lists stay until the admin changes them or the extension is removed.
The activity list keeps the newest 100 events until the admin clears it or the extension is removed.
Approval requests keep the newest 50 until they are handled or the extension is removed.
A one-page open is dropped when that page starts loading. Warning details for an open tab last until Chrome closes.
Removing Personal Web Sentry from Chrome removes the information it stored in that profile.

Children

Personal Web Sentry is a tool for an older adult, with help from an admin on the same computer. It is not directed at children under 13, and Emjay Design Lab does not knowingly collect personal information from children.

Changes

If this policy changes, the date at the top will change, and the updated policy will be included with the extension. If a later version sends anything else off this computer, this policy will say so before that version is offered.
