What Polylang adds to your visitors’ browser
No trackers In our test of Polylang 3.9.1 on 7 November 2026, the plugin itself added no tracker and no cookie. What you place in your pages with it, such as a video or a map, still counts.
What Polylang puts on your pages
- Language switcher
- Links to the other languages. It loads nothing from outside.
- Language cookie
- Remembers the visitor’s language so the next page opens in it. It serves the site itself.
- Translated pages and policies
- Each page linked to its translations, privacy policy and cookie policy included.
What matters for consent with Polylang
One language per page
Polylang links each page to its translations. The banner on a Spanish page should be in Spanish.
Translated policies
Your privacy policy and cookie policy have one translation per language. Each can fall behind the original.
The language cookie
Polylang can remember the visitor’s language in the pll_language cookie. It serves the site itself and needs no consent.
One domain per language
Polylang can put each language in a folder, a subdomain or a domain of its own. Cookies belong to one domain: with a domain per language, the visitor chooses again on each one.
Cookie Rocks with Polylang
- Lets you edit the banner texts language by language, from its list of languages.
- Points the banner’s policy link to the translation in the language of the page.

Seen in our tests, 24 October 2026, Cookie Rocks.
Full detail

For Cyprus, the dashboard warns that the law asks businesses to inform consumers in Greek or Turkish, in the cookie banner and the cookie policy, only when the site has neither language. A site in Greek only gets no language warning for Cyprus.
Good to know · Cookie RocksCookie Rocks warns when a target country requires a missing language

Depends on a setting · PolylangPolylang browser detection redirects the home page and skips its cache
setting “Detect the browser language (browser)” · by default: off
Off by default. When on, it redirects the home page by browser language and keeps the default-language home page out of the page cache, except with WP Rocket 3.0.5 or later.
Read in its code, 16 October 2026, Polylang 3.8.11.
Full detail
Polylang's browser language detection is off by default. When on, it redirects the home page with a 302 and Vary: Accept-Language, and keeps the default-language home page out of the page cache (DONOTCACHEPAGE), except with WP Rocket 3.0.5 or later.
Good to know · PolylangWith a cache plugin, Polylang writes its language cookie by script on every page
Without a cache plugin, the server sets it. Polylang uses no WP Consent API and loads nothing from other sites on visitor pages.
Read in its code, 16 October 2026, Polylang 3.8.11.
Full detail
When a cache plugin is active (WP_CACHE, or WP Fastest Cache), Polylang does not send its language cookie from the server: an inline footer script, pll_cookie_script, writes it with JavaScript on every page. Without a cache plugin it is a Set-Cookie header (SameSite Lax, not HttpOnly; SameSite None when each language has its own domain). Polylang calls no WP Consent API and loads nothing from other sites on visitor pages.

Good to know · Polylang, WPMLPolicy link follows the new address after a Polylang or WPML URL change
When URL settings are saved, Cookie Rocks forgets the stored policy address, so each language links to its own translation. Before 2.4.0 the main language kept the old address. Tested with both.
Seen in our tests, 15 October 2026, Polylang, WPML Polylang 3.8.11, WPML 4.9.2.
Full detail
When Polylang's or WPML's URL settings are saved, Cookie Rocks forgets the stored address of the cookie policy page, so after a change of URL mode (for example from language in a directory to language set from the content) each language links to its own translation at its new address. Before 2.4.0 the link in the main language kept the old address, which Polylang then redirected. Tested with Polylang 3.8.11 and WPML 4.9.2, in French and English.
Good to know · PolylangWith Polylang, the banner and cookie policy follow the page language
This works whether the language is in the address, set from the content or detected from the browser. Banner texts edited for one language show on that language's pages only.
Seen in our tests, 15 October 2026, Polylang 3.8.11.
Full detail
With Polylang, the Cookie Rocks banner and cookie policy follow the language of the page (French and English tested), whether the language is in the URL directory, set from the content, or detected from the browser on the home page. Banner texts edited for one language show on that language's pages only, and the banner's privacy link leads to the translation in the page's language.
Set before the choice · PolylangPolylang sets its pll_language cookie on the first page, before any choice
by default: on
It lasts one year, even when the language is in the address. Only code turns it off: define('PLL_COOKIE', false). In our test this left no cookie and /fr/ stayed in French.
Seen in our tests, 15 October 2026, Polylang 3.8.11.
Full detail
Polylang sets its pll_language cookie on the first page a visitor opens, before any choice: one year, path /, SameSite=Lax, not HttpOnly. It is set by default, even when the language already comes from the address (/fr/...), and can only be turned off in code with define('PLL_COOKIE', false). In our test with the language in the address, that constant left no cookie after four page views and /fr/ stayed in French. When a cache plugin is active, Polylang writes the cookie with a small script on each page instead of from the server.
How we test it
Around each version, with its latest release
Around each Cookie Rocks version, a fresh WordPress installs its latest version from WordPress.org next to Cookie Rocks and runs the same checks. A new version joins the next run on its own.
- Polylang 3.9.1, tested on 7 November 2026.
- The banner shows, the trackers of the test page wait for consent and load after it, and Cookie Rocks raises no PHP error.
- Settings of the test: Default settings after activation.
- Last run: Polylang 3.9.1 on 7 November 2026, with WordPress 7.1.3.

Questions
What if my site uses a language Cookie Rocks does not ship?
The banner shows English until you write its texts in that language, on the Appearance page.
Does a cached page show the right language?
Yes. Each language has its own banner file, so every cached page carries the right one.
Is the choice kept when the visitor switches language?
Yes when your languages are folders of one domain, since the choice is a cookie of that domain. With a separate domain per language, the visitor chooses again on each domain.
Can the banner speak the visitor's language when my site does not have it?
Yes, with the Pro. On the Appearance page, turn on « Show the banner in the visitor’s browser language » (off by default). The banner then uses the browser language among the 54 shipped, even without a version of the site in that language. The cookie and privacy policies still follow the page.
What happens after the 30-day trial?
The banner, your visitors’ choices and your proofs of consent keep working. Without a key, most settings lock, updates and support stop. Take a key at any time and everything opens again.
