Privacy Policy

What this covers

This is SiteGuardian's privacy policy. It answers three things:

1. What data we collect. 2. What we do with it. 3. Who else sees it.

If something is unclear, email siteguardian-8@polsia.app and we will explain.

The short version

• SiteGuardian does not sell user data, ever.
• We do not run advertising networks. We do not build advertising profiles.
• We collect what we need to monitor your websites and email you when something breaks.
• We share the minimum data with the third-party services that make SiteGuardian work (Stripe to bill you, a transactional email provider to send you alerts). Each of those services has its own privacy policy.

What we collect

Account data

• Email address (used to log you in and to send you alerts).
• Password (stored hashed; we cannot read it).
• If you sign in with Google, the basic profile Google returns (your email and your name, if you have one in Google).
• The date you signed up, and the date you last logged in.

Monitoring data

• The URLs you ask SiteGuardian to watch.
• The probe results. What time we checked, what response code we got, how long it took, and what SSL certificate we saw.
• The alert history. When we sent you an "it's down" email and when we sent you the "it's back" email.

Billing data

• For paid plans: what plan you are on, when you paid, the last four digits of the card, and your subscription status. The full card lives at Stripe, not on SiteGuardian's servers. See Stripe's privacy policy.

Support data

• If you email us a question, we keep the email and our reply. We treat support emails as confidential.

What we do with it

• We run the monitoring service (probes, SSL checks, alert emails).
• We bill you (via Stripe).
• We send you transactional emails: alerts when something breaks, weekly health reports on Pro and Lifetime, account emails like receipts and password resets.
• We improve the product. Specifically: we look at uptime stats, probe-response distributions, and common failure modes to figure out what to fix next. We do not use your URLs or alert content for advertising or for selling anything.

What we do not do

• We do not sell user data. That sentence is the rule, not a slogan.
• We do not use third-party advertising cookies. There is no Facebook pixel, no Google Ads tag, no "audience network" anything on SiteGuardian.
• We do not use your monitoring data to train any AI model. Ours or anyone else's.

Third-party services we use

These are the only third parties that touch your data:

• [Stripe](https://stripe.com/privacy). Processes payments for our paid plans. Stripe sees your card, billing email, invoice amount, and SiteGuardian's invoice ID. Stripe sets its own cookies on the payment pages they host for checkout. We have no control over cookies Stripe sets on their own pages; we list them in our cookie notice so you know.
• Transactional email provider. Sends you alert emails, weekly health reports, and account emails. The provider sees your email address, the subject line of the email, and the body of the email (which includes the URL we are alerting on and the failure detail).
• Hosting infrastructure. SiteGuardian runs on a managed cloud platform (database, file storage, deploys). Our hosting provider can see infrastructure-level data (encrypted at rest) but is contractually bound not to read or use it for any other purpose.
• Polsia app platform (polsia.app). The platform that hosts this app, including emails sent from this domain. They see transactional email metadata and infrastructure-level logs. They do not read your monitoring data.

If we ever need to add another processor (for example, a different email provider, or an analytics tool that is opt-in only), we will update this page before we switch it on, and we will be very explicit about what the new processor sees.

Cookies on SiteGuardian

We keep cookies to a minimum. They are listed in our cookie notice. Short version:

• Authentication cookies so you stay signed in.
• A theme preference (light or dark). That one is local to your browser.
• A "cookies dismissed" flag for this banner.

We do not set any analytics cookies. If we ever add analytics, it will be opt-in and we will update both this page and the cookie notice.

Your rights

You can:

• See what we have on you. Email siteguardian-8@polsia.app and we will send you a copy.
• Correct it. Most of it you can fix yourself from your dashboard.
• Delete it. Cancel your account and we delete what we have, except what we are required to keep for tax or fraud reasons (Stripe invoices, basic account history).

If you are a California resident, you have the rights described in the California Consumer Privacy Act. If you are in the EU or UK, you have the rights described in the GDPR. The simplest summary: email us, we explain what we have and we do the thing you asked for.

How long we hold data

• Monitoring data (probe history, alert history) is kept for as long as your account is active, plus the duration listed in your plan (7 days on Free/Starter, 90 days on Pro, 30 days on Lifetime).
• Account and billing data is kept for as long as your account is active, plus the retention period required by tax and accounting rules (typically 7 years for invoices).
• Support emails are kept as long as it's useful to keep them, then deleted.
• After you delete your account, active monitoring data is deleted within 30 days. Backup copies roll off within 90 days. Stripe retains invoices according to their own retention policy.

Children's privacy

SiteGuardian is a business tool. We do not knowingly collect data from anyone under 16. If you are a parent and you have reason to believe your child has signed up, email us and we will close the account.

Changes to this policy

When we update this privacy policy, we change the date at the top of this page. If a change is meaningful. A new third party, a new use of data, or anything that narrows a promise above. We email active paid customers a short summary.
