Koko Analytics is a plug and play privacy-friendly analytics plugin for WordPress.

== Description ==

= Plug & Play Privacy-Friendly Analytics for WordPress =

Koko Analytics is a privacy-friendly analytics plugin for WordPress sites.

It does not use any external services, so no data is shared with any third-party. Nothing specific to any individual visitor is collected, only aggregated counts.

Stop sharing visitor data with third-party companies who also happen to sell ads. Stop slowing down your website with large tracking scripts. Liberate and own your data!

Koko Analytics lets you focus on the important statistics while completely respecting the privacy of your visitors.

You can view a [live demo here](https://www.kokoanalytics.com/?koko-analytics-dashboard).

**Koko Analytics is a free plugin that does not require an account with a third-party service. It runs completely on your own server.**

### Features

- **Plug and play**: After installing and activating the plugin, statistics will automatically be collected.
- **No external services**: Any data never leaves your server.
- **No personal data** or anything visitor specific is tracked.
- **No cookies**: You can choose which tracking method to use; cookie-based, cookieless or none at all.
- **Fast**: Handles hundreds of concurrent pageviews without breaking a sweat.
- **Lightweight**: Only 500 bytes (!) of JavaScript is added to your pages. In your database, a full year worth of data will take up less than 10 MB of storage.
- **GDPR Compliant** by design.
- **Metrics**: All the essentials: total pageviews, unique pageviews and referral URL's.
- **Referrer spam:** Built-in blocklist to filter out referrer spam.
- **REST API**: You can access your data from anywhere via REST API endpoints.
- **Cached**: Fully compatible with pages served from any kind of cache.
- **Open-Source**: The plugin code is [open-sourced](https://github.com/ibericode/koko-analytics) under the GPL-3.0-or-later license.
- **Tested**: Ready for PHP 8.4, but compatible down to PHP 7.3.
- **AMP**: Tracks AMP powered pages too ([official AMP plugin](https://wordpress.org/plugins/amp/) only).
- **Import data from other plugins**: You can import historical data from Jetpack Stats or Burst Statistics.

You can install Koko Analytics in multiple ways:

- In your WordPress admin area, go to **Plugins > New Plugin**, search for **Koko Analytics** and click **Install now**.
- [Download the latest version from WordPress.org](https://downloads.wordpress.org/plugin/koko-analytics.zip) and extract the files into your `/wp-content/plugins/` directory.
- [Download the latest release from GitHub](https://github.com/ibericode/koko-analytics/releases) and extract the files into your `/wp-content/plugins/` directory.

After installing and then activating the plugin, statistics will be collected right away.

You can view your dashboard by going to **WP Admin > Dashboard > Analytics**.


== Frequently Asked Questions ==

#### Does this respect my visitor's privacy?
Yes, absolutely. Koko Analytics only stores aggregated counts. Nothing visitor specific is tracked.

#### Does this use any external services?
No.

### Does Koko Analytics set any cookies?
By default yes, but you can disable the use of cookies entirely from the plugin's settings page by choosing a different tracking method.

If using cookie-based tracking, Koko Analytics sets a single cookie named `_koko_analytics_pages_viewed` with a lifetime of at most `24 hours`. This cookie is used to accurately detect unique pageviews and returning visitors without having to store any personal information on your server.

[https://www.kokoanalytics.com/kb/does-koko-analytics-use-cookies/](https://www.kokoanalytics.com/kb/does-koko-analytics-use-cookies/)

### Will Koko Analytics slow down my website?
No, the plugin is built in such a way that it never slows down your website for your visitors.

- It only adds a single script of less than 500 bytes to your pages.
- All data processing is done in a separate background process.
- Everything lives on your server, so the plugin doesn't add any additional DNS look-ups and can benefit from your server's cache policy.

[https://www.kokoanalytics.com/kb/will-koko-analytics-slow-down-my-website/](https://www.kokoanalytics.com/kb/will-koko-analytics-slow-down-my-website/)

### Is the code for this plugin on GitHub?
Yes, see [github.com/ibericode/koko-analytics](https://github.com/ibericode/koko-analytics).

### Where can I find more documentation?
Have a look at the [Koko Analytics knowledge base](https://www.kokoanalytics.com/kb/).

### How to show number of visits to a page?
You can use the `[koko_analytics_counter]` shortcode to show the number of visitors to the current page.

It takes 3 optional arguments:

- `days`: Show count over the last N days. Defaults to "3650".
- `global`: Whether to show the global count (for the entire site) or for the current page only. Defaults to "false".
- `metric`: One of "visitors" or "pageviews". Defaults to "visitors".

Example use with arguments:

`
[koko_analytics_counter days="30" metric="pageviews" global="true"]
`

### Why are category and tag archives not tracked?
Koko Analytics is currently only able to track posts, pages and other post types. This is so that Koko Analytics does not have to store URL's or post titles, which would take up a lot of storage space.


== Screenshots ==

== Changelog ==

### 1.8.4 - Jun 18, 2025

### 1.5.5 - Jan 10, 2025

Don't use `upgrader_process_complete` for checking pending database migration. This can't be used because this specific hook runs using the old version of the plugin...

- Re-attempt installation of the custom endpoint file every hour. This also automatically re-tests whether the custom endpoint is still working as expected. The plugin already did this whenever you visited the dashboard page, but now it simply runs more often and without requiring you to log-in to your WordPress admin.
