How does PageAlert work?

Paste a URL and describe what you're looking for in plain English, like 'MacBook Pro under £1500'. AI reads the page, works out its structure, and pulls out the data. From then on PageAlert re-checks on your schedule and emails you when your conditions are met.

What kind of websites can I monitor?

Product pages, stock listings, job boards, classified ads, real estate, auction sites — anything with data on it. Some pages we can't reach: anything behind a login, sites with strong bot protection, and a few apps that only load content after you interact with them. You'll find out on the first scan rather than weeks later, and we'll tell you when a page starts blocking us.

Do I need to know CSS selectors or coding?

No. Tools like Visualping and Distill ask you to click page elements, and those break when a site changes its layout. PageAlert re-reads the page with AI every time — nothing to maintain, nothing to fix after a redesign.

How often does PageAlert check my pages?

Free accounts check every hour, Pro every 15 minutes, and Max every 5 minutes. You pick the frequency per monitor, so a page that rarely changes doesn't have to be checked as often as one that does.

How will I be notified when something changes?

Email on every plan. Telegram and Discord can be connected on any plan too, though free accounts can only point one monitor at them. Alerts say what matched, what the price did, and link straight to the item.

Is there a free plan?

Yes — 3 monitors, hourly checks, email notifications, no credit card.

What happens when my plan ends?

Your monitors stay where they are. You go back to free limits, so you can't create new monitors past the free cap or pick a faster check interval until you upgrade again, and the scrape log goes back to showing the last week. Older checks are hidden rather than removed, so upgrading again brings them back.

What do you do with my data?

We store the data we extract from the pages you monitor, so we can tell what changed between checks, along with your email address and notification settings. We don't sell it and we don't use it for advertising. Delete a monitor and its history goes with it.

2. What the service does

PageAlert is a web page monitoring service. A customer signs up, creates a “monitor” for a page they care about, and describes in their own words what they want to be told about — a visa appointment calendar where slots appear without warning, an airline's deals page, a retailer's listing for something out of stock, a council planning register.

We fetch that page on a schedule the customer chooses, compare it to what we saw last time, and when something matching their description appears we send them an alert. The alert is the product: a customer who receives no alerts has received nothing of value.

3. Where SMS fits

SMS is one of five notification channels. The others are email, browser push, Telegram and Discord. Customers choose which channels each monitor uses, and most use email. SMS exists because email is easy to miss and the other three need an account or an app the general public does not have.

Every text we send is one of exactly two things:

An alert about a change on a page the customer asked us to watch.
A one-time numeric code, sent once, to check the customer owns the number they entered.

We send no marketing, promotional offers, upsells, newsletters, surveys, political content, or messages on behalf of any third party.

4. How a customer opts in

Texts require two deliberate actions, both taken by the customer while signed in to their own account. Neither is a default, and neither is bundled with signing up or with accepting our terms.

Step 1 — Agree to receive texts, and verify the number

In Settings → Notifications the customer finds a card headed “Text message”. This is the screen, verbatim:

Text message

Get a text when something changes

Mobile number

+44 7911 123456

Start with your country code, not 0. UK, EU, US and Canada.

☐

I agree to receive text messages from PageAlert about the pages I monitor. How many depends on the monitors I choose, up to my plan's limit. Message and data rates may apply. Reply STOP to a text to stop them, or turn them off here any time. See the terms and privacy policy.

Send me a code

The tick box is empty by default and “Send me a code” stays disabled until it is ticked. A customer can use every other part of PageAlert without ever ticking it.

On pressing “Send me a code” we send exactly one message to that number:

PageAlert: your code is 481920. It expires in 10 minutes. Turn texts off any time in your dashboard settings.

The card then asks for the code back, and the number becomes eligible to receive alerts only when the correct code is entered. A number that never returns a code never receives another message from us.

Controls on this step:

The code expires after 10 minutes, and the row holding it is deleted.
Five incorrect attempts burn the code.
An account may request at most 3 codes per day.
The customer must be signed in. There is no anonymous path to this endpoint.
On the free plan a number can be claimed by one account only, so the same number cannot be registered again and again.
Destination countries are restricted to an explicit allowlist in our own code, and again at Twilio through geo permissions.

Step 2 — Choose which monitors send texts

Verifying a number sends nothing on its own. Each monitor has its own channel selection, and SMS is off by default on every monitor, including ones created before the number was verified. A customer who verifies a number and does nothing else will never receive an alert by text.

5. How a customer opts out

Per monitor: Deselect the “Text” channel on that monitor.
Entirely: Settings → Notifications → Text message → “Turn off”. This deletes the stored number.
By reply: Reply STOP to any message.
Whole account: Deleting the account removes the number with it.

Opt-out takes effect immediately. Alerts continue on whichever other channels the customer chose, normally email, so stopping texts never silently stops the service they are paying for.

6. Keywords and automatic replies

HELP: PageAlert: alerts for web pages you monitor. Manage or stop texts at pagealert.io/dashboard/settings. Msg&data rates may apply. Reply STOP to end.
START: PageAlert: you are subscribed to monitor alerts. Msg&data rates may apply. Reply HELP for help, STOP to unsubscribe.
STOP: PageAlert: you are unsubscribed and will get no more texts. Reply START to resubscribe.

7. Sample production messages

Several matches — PageAlert: 3 new matches on “Ryanair Dublin deals” https://pagealert.io/m/k17d8h2n4p9q3r5s7t1v6w8x0y2z4a6b
One match — PageAlert: 1 new match on “Visa appointment slots” https://pagealert.io/m/k17d8h2n4p9q3r5s7t1v6w8x0y2z4a6b
Price change — PageAlert: Sony WH-1000XM5 now $279.99 (was $379.00) https://pagealert.io/m/k17d8h2n4p9q3r5s7t1v6w8x0y2z4a6b
Verification code — PageAlert: your code is 481920. It expires in 10 minutes. Turn texts off any time in your dashboard settings.
Allowance used up, sent at most once a month — PageAlert: you've used your 10 texts for October. Texts resume 1 Nov. Alerts on your other channels carry on. More texts: pagealert.io/pricing

Every message begins with the brand name, so the sender is never ambiguous, and each is composed to fit a single 160-character GSM-7 segment.

8. Message frequency

Frequency follows the customer's own monitors, so it varies. It is capped in the product, per customer, per calendar month and per day:

Plan	Per month	Per day
Free	10	3
Sprint	25	10
Pro	60	20
Max	200	50

The daily cap exists so a page that starts changing erratically cannot produce a burst of messages. On reaching the monthly cap we send one message saying so and then stop; alerts continue by email and any other channel you have on until it resets. A separate ceiling applies across all customers combined — if it is reached, SMS stops entirely and every alert falls back to email.

9. What we never do

We never send marketing or promotional messages.
We never send messages on behalf of a third party.
We never sell, rent, share or licence phone numbers.
We never buy, import or upload lists of numbers. Every number was typed in by its owner and confirmed by a code sent to it.
We never send to a number that has not completed verification.
We never enable texts on a monitor without the customer doing it.
We send nothing in the categories carriers prohibit, including cannabis, CBD, firearms, gambling, high-risk lending, debt collection, adult content, and cryptocurrency promotion.

10. Data handling

What we store: The number in E.164 format, a flag saying it is verified, and the per-monitor channel choices. Message bodies are built at send time and not kept as a messaging history.
Where: Convex, EU region.
Verification codes: Held for at most 10 minutes, then deleted. Deleted immediately on success, and swept hourly if abandoned.
Retention: The number is held until the customer removes it or deletes their account, then deleted.
Access: The customer can see and remove their number at any time in Settings.
Processor: Twilio Inc. No other party receives the number.
Governing policy: pagealert.io/privacy

11. Eligibility and geography

The service is not directed at children, and customers must hold an account in their own name. Text destinations are restricted to an explicit allowlist enforced in our own code and again at Twilio through geo permissions. Any country not on that list is rejected before a message is composed.

12. Status

The SMS channel is built and waiting on carrier registration before being switched on for customers. The screens, controls and message text quoted above are the implemented behaviour, taken from the product itself, not a proposal.

No text message has been sent to any customer to date. The first production message will go out only once registration is approved.

The above is an accurate description of how PageAlert collects consent and sends messages. — James Dimonaco, Director, J M Dimonaco LTD
