Privacy Policy

Last updated: October 30, 2026

UserAlertX is a service of Xpandable Technology Lab LLC. This explains what we collect, why, and what we do (and don't do) with it.

What we collect

Email address — required for every account, used to verify you and to deliver email alerts.
Phone number — only if you choose SMS delivery, used solely to verify your number and deliver your alerts after you provide SMS consent and reply START to the verification message.
Alert content — the messages you or your connected bot/program send through the service, so we can deliver them.
Billing information — handled directly by Stripe, our payment processor. We don't store your card details ourselves.
Which tool sent each alert — e.g. one of our example programs, Home Assistant, or the GrokBot connector, so we can see which integrations people use and improve them. It's never used to decide how an alert is handled.
How you found us — when you visit useralertx.com, our own site records the page you arrived on, the site that linked you here (e.g. a search engine or a post), any campaign tags on the link, and a random visitor ID kept in your browser, so we can see which links and ads bring people here. Your IP address is not stored (only a scrambled form, to tell visitors apart). This stays on our own servers — no third-party analytics or advertising trackers.
Agent inbox mail — only if you make an agent inbox address (a UserToolX tool). We keep the mail sent to that address (sender, subject, date and the text; for attachments, only their names) so you and the AI assistant you connect with your API key can read it. It is never read by us except to run the service or when you ask for help, never shared with anyone else, and deleted after 30 days (or the 1 or 7 days you choose), or right away when you delete it or your inbox. If you add a webhook address, we send each new message's sender, subject, date and a short preview to that address — only where you tell us to.
UserSummaryX requests — only if you turn on UserSummaryX (a UserToolX tool). We keep the link (or the name of the PDF), the summary we email you, the price and the date, so they show on your UserSummaryX page. The text being summarized — a video's captions or its sound turned into text, an article, a PDF or text you paste — is sent to OpenAI, our AI provider, to make the summary, and is not kept by us after your email is sent.
FaxAlertX faxes — only if you turn on FaxAlertX (a UserToolX tool). Faxes you receive: we keep the fax (a PDF), the sender's fax number, the page count and the date. A fax with your code is read by our own servers only — no person and no AI sees it. A fax with no code has its first page sent to OpenAI to read who it's addressed to (name, email, phone, address); if that doesn't exactly match one you listed, it waits privately in a claim queue, and our support staff look at it only to find its owner when someone claims it. Faxes you send: we keep the PDF, the cover-sheet details you type, the fax number it went to, the name printed on each page and the result. The names, emails, phone numbers and addresses you list for matching are kept with your settings.
Do-not-fax requests — when anyone asks us not to send faxes to a number, we keep that fax number, permanently, so FaxAlertX users can't fax it.

Your mobile number and SMS opt-in consent are never shared or sold to third parties for marketing purposes. They're used only to operate UserAlertX itself.

SMS Messaging

SMS delivery is optional. If you choose SMS delivery, you must actively consent on the UserAlertX account screen and verify control of your mobile number before alerts are delivered. Message frequency varies based on the alerts you create and trigger. Message and data rates may apply. Reply STOP at any time to stop SMS delivery, or HELP for help.

How we use it

Solely to run the service: creating and verifying your account, delivering the alerts you send, billing (via Stripe), and responding if you contact support. If you check the new tools box, we also email you now and then when a new tool comes out — email only, never by text, and every one has an unsubscribe link. We don't use your data for advertising, and we don't sell it.

Who we share it with

Only the vendors that make the service work: Twilio (SMS delivery), our email infrastructure (email delivery), Stripe (billing), Telnyx (sending and receiving FaxAlertX faxes), and OpenAI (the AI that makes UserSummaryX summaries, only for summaries you ask for, and that reads the first page of a fax that has no fax code) — each only receives what they need to perform that function. We don't share your data with anyone else, and never for their own marketing purposes.

How long we keep it

For as long as your account is active (agent inbox mail and UserSummaryX summaries: 30 days at most; a fax you receive: 7 days after we email it to you, or 14 days if it waits unclaimed; a fax you send: 7 days, after which we keep only its record - the number, pages, date and result). If you delete your account, we remove your personal data except where we're required to keep records (e.g. billing history) for legal or accounting purposes.

Your choices

Reply STOP to any text to stop SMS delivery immediately.
Unsubscribe from email alerts via the link in any alert email.
Contact us to request a copy of your data or full account deletion.

Security

Your API key is shown only on your own account screen, while you're signed in, and is never emailed. We don't store payment card numbers — that's handled entirely by Stripe.

Changes to this policy

We may update this policy as the service evolves. Material changes will be reflected here with an updated date above.
