External Services & Data Privacy

SitePulse uses an external service to provide enhanced features including PageSpeed analysis and AI-powered diagnostics.

🔗 External Service Integration

SitePulse communicates with api.sitepulse.me (operated by the plugin developer) to provide:
– PageSpeed Reports – Google PageSpeed Insights analysis with performance scores, Core Web Vitals metrics, and page screenshots
– AI Diagnostic Reports – AI-powered performance analysis and optimization recommendations
– Remote Management (optional) – lets your SitePulse dashboard show this site’s backups (UpdraftPlus or BackWPup) and its plugin, theme and WordPress updates, and start, cancel or set up its backups. It stays off until you turn it on for the site in your SitePulse dashboard, and you can block it in SitePulse’s settings.

📊 What Data is Collected?

To provide these enhanced features, SitePulse sends only performance-related metrics to the external API:
– Plugin names, versions, and slugs installed on your site
– WordPress hook execution times and memory usage
– API request URLs and response times
– Site domain name
– Performance statistics and load times

🔒 What Data is NOT Collected?

SitePulse is designed with privacy in mind and does NOT collect:
– ❌ Personal user data (names, emails, passwords, IP addresses)
– ❌ User content (posts, pages, comments, custom data)
– ❌ Database content or sensitive information
– ❌ Customer or visitor information
– ❌ Any personally identifiable information (PII)

🔁 Remote Management

While Cloud Services (PageSpeed & AI Reports) are on, the site checks in with api.sitepulse.me every hour, and every 5 minutes while remote management is on. A check-in sends the SitePulse and WordPress versions, which backup plugin is active, whether remote management is blocked on the site, how WP-Cron runs there: the address of wp-cron.php, whether WP-Cron is turned off and how long scheduled tasks have been waiting, and whether the site’s own server can reach its wp-admin, as the plugin’s hourly check found it: the HTTP status of wp-admin and the login page, how long they took, when it checked and, when they failed, why (a timeout, a connection error, an HTTP status or a PHP fatal error, with the first line of the error message, up to 200 characters).

Only while remote management is on, the site also sends:
– Plugin and theme names, versions, whether they are active, their auto-update setting and available updates
– WordPress, PHP and database versions and the site language
– Backup schedules, how many backups are kept, storage types, the result of the last backup and the dates and sizes of recent backups
– Events when plugins, themes, translations or WordPress are updated, a plugin is activated or deactivated, the theme changes or a backup finishes
– Page speed figures from SitePulse’s profiler: once a day, the time plugins, themes and WordPress took per page load the day before (with the five slowest), and after each update, the updated item’s time on the full day before and the full day after it
– PHP fatal errors in SitePulse’s error log: the first line of the message (up to 300 characters), the file and the line
– How far a running update or undo is: its step, the backup’s progress and the item it is on

While remote management is on, the dashboard can also:
– Start or cancel a backup, and apply backup settings saved in your dashboard (schedules, how many backups to keep, which parts of the site to include) to UpdraftPlus or BackWPup. It restores a backup only when you undo a safe update from the dashboard (see below), and never deletes backups or changes where they are stored.
– Update plugins, themes and WordPress, on request or automatically under the site’s update policy (by default security and minor updates, three days after release, between 1 and 5 am site time). Updates run through WordPress’s own updater, so they come from WordPress.org or a premium plugin’s own updater, never from api.sitepulse.me. Each update is preceded by a backup and followed by a check of the home page, wp-admin and, with WooCommerce, the cart and checkout; a plugin or theme that breaks them is rolled back to its previous version.
– Run a safe update of one plugin or theme. First the plugins (or themes) folder and the database are backed up with UpdraftPlus or BackWPup; without a backup plugin there is no backup. SitePulse’s screenshot service loads the site’s monitored public pages (the home page by default) just before and just after the update and compares them. If a page changed a lot or stopped loading, the dashboard offers to keep the update or undo it. With an UpdraftPlus backup, undoing restores that folder and the whole database to the time of the backup, so anything saved since (such as orders, comments or form entries) is lost; otherwise it reinstalls the previous version from WordPress.org. After an undo, WordPress’s own automatic updates do not install the undone version again, for 90 days or until a newer version is installed.
– Turn WordPress’s own automatic updates on or off for plugins and themes.

Remote management runs in WP-Cron, which WordPress only runs when the site gets visitors unless a server cron job runs it. So while remote management is on, api.sitepulse.me requests the site’s wp-cron.php, at most once a minute, when the dashboard has work waiting for the site or the site has stopped checking in. That request sends no data; with ?sitepulse_check_in=1 the site checks in during that run instead of at its next scheduled check-in.

Requests are signed with the site’s SitePulse license, or with a key the dashboard rotates for remote management; the license key itself is never sent. Remote management never sends backup files, passwords, storage credentials or site content, and SitePulse never installs code from api.sitepulse.me. Turn on “Block remote management” in SitePulse’s settings to stop it on this site at any time, whatever the dashboard says.

1.5.0

• New: Remote management (optional). Your SitePulse dashboard can show this site’s plugins, themes and available updates, plus a history of updates, plugin changes and backups, and update plugins, themes and WordPress, on request (on one site, or on all your sites at once) or under an update policy (by default security and minor updates, after three days, at night): a backup first when UpdraftPlus 1.26+ or BackWPup 5 is active, then one update at a time through WordPress’s own updater, each checked on the home page, wp-admin and WooCommerce’s cart and checkout, and rolled back when it breaks them. With UpdraftPlus 1.26+ or BackWPup 5 active, the dashboard also shows this site’s backup schedules and recent backups, can start or cancel a backup and apply saved backup settings (schedules, how many backups to keep, what to include), and warns about backups kept only on the server, missing or overdue backups and unusually small ones. The dashboard also shows how each update changed page speed (the full day before against the full day after), daily page speed and PHP fatal errors in one timeline of everything that changed on the site, builds monthly client reports, and can alert you by email, Slack or webhook when an update or backup fails, check-ins stop or the site slows down. It is off until you set the site up in your dashboard with its connection key, and you can block it at any time under SitePulse Settings. An update cut short by a PHP time limit or crash takes the site out of maintenance mode and puts the previous version back, and the dashboard can rotate the key remote management signs with.
• New: safe update of one plugin or theme from your dashboard: the plugins (or themes) folder and the database are backed up first, screenshots of the site’s monitored pages taken just before and after the update are compared, and when a page changed a lot or stopped loading you can keep the update or undo it. Undoing restores the folder and the whole database from the UpdraftPlus backup (anything saved since is lost), or without one reinstalls the previous version from WordPress.org.
• New: connect this site to your SitePulse dashboard with a connection key, as with ManageWP: choose Get connection key under SitePulse Settings → Remote Management (or the Connection key link on the Plugins screen), then enter the site’s address and the key in your dashboard. A site with the free plugin joins one of your plans, and it is set up at once: it registers with SitePulse if needed, checks in as soon as the key is used, even when its WP-Cron does not run, and the settings page updates by itself. You can disconnect it from the settings at any time.
• New: SitePulse checks every hour, from the site’s own server, that wp-admin and the login page load, the way WordPress checks an edited plugin for errors. Site Information (System Information in the Advanced dashboard’s settings) and the toolbar show whether wp-admin can be reached, why not when it cannot (a timeout, a blocked connection, an HTTP error or a PHP fatal error) and since when, with a Check now button, and each check-in tells your SitePulse dashboard, which warns that updates would stop.
• New: remote management also works on sites where WP-Cron does not run by itself (few visitors, or DISABLE_WP_CRON without a server cron job): api.sitepulse.me wakes the site’s WP-Cron when the dashboard has work for it, so updates and backups start within about a minute, and the dashboard warns when a site’s WP-Cron is not running, with the server cron job to add. When a check-in is 10 minutes late, an administrator’s wp-admin page checks in after it loads.
• Fixed: with SitePulse active, WordPress’s plugin and theme editors missed most PHP fatal errors in edited code (those PHP reports as uncaught exceptions, such as a call to a missing function), because SitePulse’s error log caught them first. WordPress now sees them again; SitePulse still logs each one.
• Fixed: an AI diagnosis on a site without a license key (for example, after its key was removed) failed with “the license key field is required”. The site now registers with SitePulse first and gets a key; when SitePulse refuses, the message says why.
• Fixed: the vulnerability scan said “Vulnerabilities detected.” on a site with none, answered “Free scan requests exhausted” to any refused request, and showed nothing in Easy Mode while the first scan waited in the queue. It now says when the queued scan was requested and when to check again, counts the findings, and explains a refusal (daily limit, Pro license, SitePulse temporarily unavailable).
• Fixed: Easy Mode said “No Threats Found” before the first vulnerability scan, and showed the severity of every finding as “Unknown”.
• Fixed: a failed AI diagnosis kept showing “Waiting in queue” and could start a new diagnosis by itself an hour later. It now shows the failure, the reason SitePulse gave and a retry button. A temporary server error no longer marks a diagnosis as failed or hides the previous report.

1.4.7

• Fixed: after SitePulse had been running for a while, warnings kept blaming plugins that were slow in the past or that simply ran often. Warnings, rankings, scores and AI diagnostics now use the last 24 hours and the time each plugin’s own code adds to a page load.
• Fixed: slow external requests from earlier days no longer appear as warnings or in diagnoses; the External Requests log still lists them.
• Fixed: “Slowest Plugins” lists plugins slowest first, with averages over the last 24 hours.
• Fixed: the dashboard assistant showed “?ms” for the slowest item and based its heaviest-plugin tip on outdated timings.
• Improved: Plugin Activity forgets code that has not run for two days, so stored data stays small.

1.4.6

• New: Page Analysis. Analyze any page (products, posts, archives, your shop, search results) and see which plugins, theme code and external requests slow it down, with plain-English findings. Replaces the old single-page tracking, which only supported posts and pages and mixed in data from other requests.
• New: “Analyze this page” in the toolbar on every front-end page.
• New: when the server cannot load its own pages, Page Analysis measures your browser visit instead.
• New: Pause and resume monitoring from the toolbar, without deactivating.
• New: getting-started checklist on the dashboard.
• Improved: the Simple dashboard (Easy Mode) is now the default; the classic dashboard is the “Advanced view”. Dashboard preferences are saved per user instead of per browser.
• Improved: onboarding ends with a real check-up of your homepage.
• Improved: plain menu names: Page Analysis, Plugin Activity and External Requests.
• Improved: profiler measures each callback’s own time, so nested plugins are no longer counted twice.
• Improved: pages for visitors no longer load jQuery or SitePulse styles; only administrators who see the toolbar do.
• Improved: the deactivation dialog offers to pause instead, a quick-start guide and a support link, and can be translated.
• Improved: uninstalling also removes the error log and plugin timing data.
• Fixed: switching off External Requests tracking now really stops it (it kept recording before), and the dashboard switches confirm the right state.
• Fixed: single-file plugins (such as Hello Dolly) appear under their own name in Plugin Activity.
• Fixed: a deprecation notice from the error handler on PHP 8.4 and newer.
• Fixed: PHP warnings and errors (such as “Undefined array key avg_ms”) when a site still holds data saved by earlier versions or damaged data.
• Removed: the simulated “Real-Time Tracking” modal on the front end.
