Find WooCommerce reviews that need attention, and keep a clear record of how they were checked.

Synth Review Integrity brings review history, order-match results and documented decisions into one dashboard. Use it to investigate unfamiliar review batches, check verified-owner claims and hand cases to the right person.

Once connected, it records product reviews and their changes in the background. It never changes, publishes or deletes reviews, orders, coupons or ratings.

Findings highlight records to investigate. The plugin does not determine whether a review is fake.

How you use it

Your usual WordPress moderation remains in place. Findings become cases in the dashboard. Make corrections in WordPress; when the dashboard sees that the issue is fixed, the case closes as fixed at the source. Checks and decisions stay on record.

What it checks

A batch of reviews whose source is unknown, such as an import — one case per batch.
A “verified owner” mark without a matching purchase on this site.
A review that Customer Reviews for WooCommerce links to an order without the reviewed product.
Exact duplicates of a long review text within your shop.
A review that changed after a check: earlier results become outdated and the review is checked again.
Gaps in what the dashboard knows about your shop — reported once per period.
A review already identified as an ad by Synth Antispam. Its verdict is reused without checking the text again; this check needs Synth Antispam on the same site.

Order matching happens on your site, through WooCommerce. The service receives the match result and a pseudonym of the order. Order numbers, order contents and customer details stay on your site.

The dashboard

Stores & Coverage — see how complete and fresh each shop’s data is.
Reviews — inspect a review’s versions and check results, then open it in your WordPress admin.
Cases — assign, add notes, resolve with a reason, dismiss, reopen and recheck.
Members — invite people by email as Owner, Operator or Viewer. Sign-in uses a one-time email link; there are no passwords.
Export — download a ZIP of reviews, checks and history, with a manifest of checksums.

Privacy

By default, only facts and keyed one-way digests leave the site. Reviewer names, email addresses, websites and IP addresses never do.
Review text is sent only if the workspace owner enables content consent in the dashboard.
Connecting a shop excludes its domain from Synth Antispam training copies, including Antispam checks on that site. Disconnecting does not reverse this.
The plugin sends nothing while a visitor is submitting a review.

The “External services” section below lists what is sent, when, and how long it is kept.

Requirements

WooCommerce. Without it, the plugin records and sends nothing.
A workspace at reviews.synth.locker. Creating one takes an email address and costs nothing. What it includes — how many shops, continuous tracking of new reviews and rechecks — is shown in the dashboard.
Synth Antispam is optional. It is recommended for the ad-review check and is not required for the other checks.

External services

This plugin needs the Synth Review Integrity service (wp-api.synth.locker, operated by LightApps OÜ, Estonia). Once an administrator activates the plugin, gets a site key and connects the shop to the Synth Review Integrity dashboard with a pairing code, the plugin records how WooCommerce product reviews are created, edited and moderated, reads WooCommerce orders locally on this site to check whether a reviewer bought the product and, when Customer Reviews for WooCommerce links a review to an order, whether that order contains the reviewed product, and sends only the resulting facts to the service. The text of a review is sent only if the shop owner has enabled content consent in the Synth Review Integrity dashboard, and only for review versions the plugin records after it was enabled (a new or changed review, or a scan the dashboard asks for); turning the consent off stops new transfers. Orders are read on this site only; what leaves it is the fact of a match and a pseudonym of the order — and, for a linked order, only whether it contains the product, never its number. Until the shop is connected, the plugin sends nothing except the two requests an administrator makes by pressing a button on its screen — Get a site key and Connect — and nothing is ever sent while a visitor is submitting a review: sending happens later, in the background.

Requests the plugin makes

Every request below carries the plugin version and WordPress’s own User-Agent header; all except POST /v1/register also carry the site key and, in a separate header, the site address. POST /v1/register carries instead the plugin’s name (X-Synth-Product: review-integrity), so the service can tell this plugin’s site keys from Synth Antispam’s — nothing about the site.

POST /v1/register — only when an administrator presses Get a site key on the plugin’s screen; asks the service for this plugin’s own site key with an empty body — no site key and no site address header. The key is tied to this site’s address by the first request made with it (connect).
POST /v1/integrity/connect — only when an administrator presses Connect with a one-time pairing code from the dashboard; sends the code, a random identifier of this installation and the capability snapshot.
POST /v1/integrity/events — in the background while the shop is connected; sends up to 50 review events at a time.
POST /v1/integrity/status — in the background, at most once every 15 minutes; sends the capability snapshot and the state of the local queue, and receives scan jobs.
POST /v1/integrity/scan/page — in the background, only while the dashboard has asked for a scan or a recheck; sends review snapshots page by page.
POST /v1/integrity/erasure — in the background, only after the shop owner erases a person’s personal data with the WordPress privacy tools (Tools Erase Personal Data); sends the numbers of that person’s product reviews on this site, found here by the email address, and a random request id — never the email address itself.

What is never sent: reviewer name, reviewer email address, reviewer website, reviewer IP address, order number, order contents, amounts, addresses.

Sent only with the shop owner’s consent: review text — only while the shop owner has enabled content consent in the Synth Review Integrity dashboard, and only for versions captured after it was enabled.

Retention on this site: events wait in a local table and are deleted 7 days after they were recorded, sent or not; the number deleted unsent is reported (outbox.dropped_total) so the gap is visible. An erasure request is the exception: it is kept until it is sent — while the shop is disconnected it waits for the shop to be reconnected — and is then deleted like the rest. Uninstalling the plugin removes the table and the per-site secret behind every pseudonym and digest, after which earlier pseudonyms can no longer be linked to anything on this site.

Training: nothing this plugin sends is used to train models. Connecting the shop also excludes its domain from the copies the Synth Antispam service keeps for training: from then on, checks made for that domain — including those of Synth Antispam on this site — are not kept. Disconnecting the shop does not undo this. Copies taken before the shop was connected are deleted on request: write to [email protected] with the site address.

Every address that appears in the source

A search of this plugin’s files finds these addresses and no others:

wp-api.synth.locker — the Synth Review Integrity service above; changeable only with the SYNTH_RI_API_BASE constant in wp-config.php or the synth_ri_settings filter. The only address this plugin sends a request to.
reviews.synth.locker — the Synth Review Integrity dashboard, where pairing codes are issued: a link on the plugin’s settings screen. Nothing is sent to it.
wordpress.org — a link to Synth Antispam on the plugin’s settings screen, shown while Synth Antispam is not installed, and the support forum in the translation template. Nothing is sent to it.
synth.locker, www.gnu.org and fsf.org — links (the plugin’s home page, the terms and the privacy policy above, the GPL licence). Nothing is sent to them.
[email protected] — the email address for deletion requests.
Not addresses: the translation-template placeholder [email protected]; localhost, 127.0.0.1 and the .test, .local and .localhost endings, by which the plugin recognises a development address of the service and allows it without HTTPS; and [email protected], an example inside a code comment. None of them is contacted.
