  Get Matomo for WordPress

  What do you get ?

  • No more signing up to third party analytics service (like Google)
  • No more sending away your valuable data to a third party service (like Google)
  • Easy setup – install with a few clicks, no tracking code installation or developer knowledge needed
  • 100% accurate data – no data sampling and no data limits 
  • Full data ownership – all data is stored on your servers and no one else can see your data

  • Ecommerce tracking out-of-the-box (Woocommerce, Easy Digital Downloads, and MemberPress) and we’re keen to add many more over time
  • Powerful features – segmenting, comparing reports, different visualisations, real-time reports, visit logs and visitor profiles, Matomo Tag Manager, dashboards, data export, APIs, and many more
  • Compared to other WordPress solutions we don’t charge you extra for basic features that should work out-of-the-box
  • Just like Matomo On-Premise, Matomo Analytics for WordPress is free

  We need your feedback !

  We all know and love the versatility of WordPress – with over 55,000 plugins and all the different ways of hosting it. However, with this great versatility comes the potential for things to be missed, so we’re keen to hear your feedback.

  • Is our plugin breaking anything on your WordPress, or, not compatible with something ? Please create an issue on our repository.
  • Is something not working ? If so, what ? Please create an issue on our repository.
  • How does running Matomo impact the performance of your WordPress server ? Also, if you have any other feedback for us – whether good or bad – please email us at wordpress@matomo.org. We’d love to hear what you think !
  • Can you perform a security review of the plugin ? Security issues are best reported to security@matomo.org
  • Do you have any questions ? Questions are best asked in our forum

  Thank you ! We really appreciate your help on this ❤️

  How do you get Matomo Analytics for WordPress ?

  Get Matomo for WordPress

  Log in to your WordPress and go to “Plugins => Add New”, search for “Matomo Analytics – Ethical Stats. Powerful Insights”, click on “Install” and then “Activate”.

  All you need is at least WordPress 4.8 and PHP 7.0 or later. MySQL 5.1+ is recommended. 

  The source code is available at : https://github.com/matomo-org/wp-matomo/. 
  

  In perfect harmony : Matomo and WordPress

  

  The idea for this started two years ago when we realised the similarities between the Matomo and WordPress project. 

  Not only from a technological point of view – where both are based on PHP and MySQL and can be extended using plugins – but also from a philosophical, license and values point of view. We both believe in privacy, security, data ownership, openness, transparency, having things working out-of-the-box, simplicity etc. 

  WordPress is currently used on approximately 30% of all websites. Many of them use the self-hosted open-source WordPress version. Giving everyone in this market the opportunity to easily get a powerful web analytics platform for free, means a lot to us. We believe WordPress users get a real choice besides the standard solution of Google Analytics, and it furthers our effort and goal of decentralising the internet. 

  We’re hoping more people will be empowered to protect user privacy, have access to a great free and open-source tool, and keep control of data in their own hands.

  We hope you feel the same. Help us spread the word to your friends and get them in on this awesome new project !

  FAQs

  Isn’t there already a WP-Matomo plugin for WordPress available ?

  Yes, the existing WP-Matomo (WP-Piwik) plugin is an awesome plugin to connect your existing Matomo On-Premise or Matomo Cloud account with WordPress. The difference is that this new plugin installs Matomo Analytics fully in your WordPress. So you get the convenience of having a powerful analytics platform within your WordPress.

  We highly recommend you install this new plugin if you use WordPress and are not running Matomo yet. 

  If you are already using Matomo on our Cloud or On-Premise, we’d still highly recommend you use WP-Matomo (WP-Piwik). So that you get an easier way of inserting the tracking code into your WordPress site and get insights faster.

  I have a high traffic website, will it be an issue ?

  If you have a lot of traffic, we’d advise you to install Matomo On-Premise separately. There’s no specific traffic threshold we can give you on when it’s better to use Matomo On-Premise. It really depends on your server. 

  We reckon if you have more than 500,000 page views a month, you may want to think about using Matomo On-Premise with WP-Matomo instead, but this is just an estimate. In general, if the load on your server is already quite high, then it might be better to install Matomo on a separate server. See also recommended server sizing for running Matomo.

  How do I report a bug or request a new feature in Matomo for WordPress ?

  Please create an issue, on our repository whenever you find a bug or if you have any suggestion or ideas of improvement. We want to build an outstanding analytics experience for WordPress !

  Have another question you’re dying to ask ? The Matomo for WordPress FAQ page might have the answer you need.

• MOV to ACVHD conversion via Spring Boot and FFmpeg leads to file system error

  31 décembre 2024, par epicUsername

  I am experiencing an issue on a personal project that seeks to convert HEIC to JPG files and MOV files to AVCHD format. The HEIC to JPG conversion works, but the MOV to AVCHD does not, which is where my problems lie.

  


  The intent is to do this with Spring Boot and FFmpeg, using a simple interface done in WindowBuilder.

  


  The relevant bits are the pom file :

  A few caveats :

  


  


  1. I did explore FFmpeg and GStreamer for this project. GStreamer was inconclusive, with available version for it that were too old for use with my current state of STS4.27 and Java 17, even if this version of Java is under long-term support...

     


  


  2. I've used AI to tell me about the options and suggest ways to build this thing, since multimedia handling is very far away from my skillset. I don't have a good conceptual grasp of video formats and how they transfrom from one to another.

     


  


  


  The issue, as I have identified it, occurs at these lines :

  


   // Ensure the destination file is writable
                    if (!destinationFile.canWrite()) {
                        JOptionPane.showMessageDialog(null, "Output file is not writable.", "File Error", JOptionPane.ERROR_MESSAGE);
                        return;
                    }


  


  ^^ And this, while temporarily commented out for testing, it meant to compensate for an issue that occurs here in the conversion function :

  


   if ((outputFormatContext.oformat().flags() & avformat.AVFMT_NOFILE) == 0) {
                // Ensure the output path has the correct extension
                String outputPath = destinationFile.getAbsolutePath().replace("\\", "/") + ".avchd";
                System.out.println("Normalized output path: " + outputPath);

                // Try opening the output file
                int ret = avformat.avio_open(outputFormatContext.pb(), outputPath, avformat.AVIO_FLAG_WRITE);
                if (ret < 0) {
                    BytePointer errorBuffer = new BytePointer(avutil.AV_ERROR_MAX_STRING_SIZE);
                    avutil.av_strerror(ret, errorBuffer, errorBuffer.capacity());
                    System.out.println("Failed to open output file: " + errorBuffer.getString());
                    return;
                }
            }


  


  The idea here is that the avio_open() function requires the use of the a valid file path that it can open to be able to write it.

  


  Padadoxically, the file conversion seems to work, but the project crashes with a fatal error in the console :

  If anyone has a perspective on this, it'd be appreciated.

  


  The catch 22 in this project is that pre-creating the file is not a good idea, since avio_open has a purpose in-built method for that (I tried). Error checking everything about Java's File class in terms of setting pathways and creating and deleting files is not problematic. Likewise, permissions are all fine (Full Control in source and target folders) ; I've tested default C drive folders, which have restritions, to a separate volume and removable media, to no effect. Likewise, FFmpeg requires a forward slash, "/" in file paths, whereas Java does the backslash, generally. That's been handled with the replace method in the above conditioning, also to no effect.

  


  The basic contradiction in the project seems to be that the error tries open a file that does not exist, with a valid source and destination file, and if I try to create a placeholder file wiht an acvhd extension at the event handling for the Convert button, it still errors out ; meanwhile, FFmpeg allegedly handles the file creation at its core, but requires a valid path to be passed ; I've tried with and without a filename, with and without an extension. I'm not able to resovle it.

  


  The excessive error handling conditions are in an effort to isolate the problem, which I think I've done.

  


  There also seems to be a compatibility between mpegts and acvhd, which is why I also had that format specified in the conversion function, without result.

  


  I also have the idea to be able to do this without having to install any libraries locally or having to set path variables, which is an aspect that both GStreamer and FFmpeg have.

  


  Nearest suggestion I've found is this : integrate ffmpeg with spring boot

  


  AI remains hopeless for resolving this issue.

  


• Virginia Consumer Data Protection Act (VCDPA) Guide

  27 septembre 2023, par Erin — Privacy

  Do you run a for-profit organisation in the United States that processes personal and sensitive consumer data ? If so, you may be concerned about the growing number of data privacy laws cropping up from state to state.

  Ever since the California Consumer Privacy Act (CCPA) came into effect on January 1, 2020, four other US states — Connecticut, Colorado, Utah and Virginia — have passed their own data privacy laws. Each law uses the CCPA as a foundation but slightly deviates from the formula. This is a problem for US organisations, as they cannot apply the same CCPA compliance framework everywhere else.

  In this article, you’ll learn what makes the Virginia Consumer Data Protection Act (VCDPA) unique and how to ensure compliance.

  What is the VCDPA ?

  Signed by Governor Ralph Northam on 2 March 2021, and brought into effect on 1 January 2023, the VCDPA is a new data privacy law. It gives Virginia residents certain rights regarding how organisations process their personal and sensitive consumer data.

  

  The law contains several provisions, which define :

  • Who must follow the VCDPA
  • Who is exempt from the VCDPA
  • The consumer rights of data subjects
  • Relevant terms, such as “consumers,” “personal data,” “sensitive data” and the “sale of personal data”
  • The rights and responsibilities of data controllers
  • What applicable organisations must do to ensure VCDPA compliance

  These guidelines define the data collection practices that VCDPA-compliant organisations must comply with. The practices are designed to protect the rights of Virginia residents who have their personal or sensitive data collected.

  What are the consumer rights of VCDPA data subjects ?

  There are seven consumer rights that protect residents who fit the definition of “data subjects” under the new Virginia data privacy law. 

  

  A data subject is an “identified or identifiable natural person” who has their information collected. Personally identifiable information includes a person’s name, address, date of birth, religious beliefs, immigration status, status of child protection assessments, ethnic origin and more.

  Below is a detailed breakdown of each VCDPA consumer right :

  1. Right to know, access and confirm personal data : Data subjects have the right to know that their data is being collected, the right to access their data and the right to confirm that the data being collected is accurate and up to date.
  2. Right to delete personal data : Data subjects have the right to request that their collected personal or sensitive consumer data be deleted.
  3. Right to correct inaccurate personal data : Data subjects have the right to request that their collected data be corrected.
  4. Right to data portability : Data subjects have the right to obtain their collected data and, when reasonable and possible, request that their collected data be transferred from one data controller to another.
  5. Right to opt out of data processing activity : Data subjects have the right to opt out of having their personal or sensitive data collected.
  6. Right to opt out of the sale of personal and sensitive consumer data : Data subjects have the right to opt out of having their collected data sold to third parties.

  Right to not be discriminated against for exercising one’s rights : Data subjects have the right to not be discriminated against for exercising their right to not have their personal or sensitive consumer data collected, processed and sold to third parties for targeted advertising or other purposes.

  Who must comply with the VCDPA ?

  The VCDPA applies to for-profit organisations. Specifically, those that operate and offer products or services in the state of Virginia.

  

  Additionally, for-profit organisations that fit under either of these two categories must comply with the VCDPA :

  • Collect and process the personal data of at least 100,000 Virginia residents within a financial year or
  • Collect and process the personal data of at least 25,000 Virginia residents and receive at least 50% of gross revenue by selling personal or sensitive data.

  If a for-profit organisation resides out of the state of Virginia and falls into one of the categories above, they must comply with the VCDPA. Eligibility requirements also apply, regardless of the revenue threshold of the organisation in question. Large organisations can avoid VCDPA compliance if they don’t meet either of the above two eligibility requirements.

  What types of consumer data does the VCDPA protect ?

  The two main types of data that apply to the VCDPA are personal and sensitive data. 

  

  Personal data is either identified or personally identifiable information, such as home address, date of birth or phone number. Information that is publicly available or has been de-identified (dissociated with a natural person or entity) is not considered personal data.

  Sensitive data is a category of personal data. It’s data that’s either the collected data of a known child or data that can be used to form an opinion about a natural person or individual. Examples of sensitive data include information about a person’s ethnicity, religion, political beliefs and sexual orientation. 

  It’s important that VCDPA-compliant organisations understand the difference between the two data types, as failure to do so could result in penalties of up to $7,500 per violation. For instance, if an organisation wants to collect sensitive data (and they have a valid reason to do so), they must first ask for consent from consumers. If the organisation in question fails to do so, then they’ll be in violation of the VCDPA, and may be subject to multiple penalties — equal to however many violations they incur.

  A 5-step VCDPA compliance framework

  Getting up to speed with the terms of the VCDPA can be challenging, especially if this is your first time encountering such a law. That said, even organisations that have experience with data privacy laws should still take the time to understand the VCDPA.

  

  Here’s a simple 5-step VCDPA compliance framework to follow.

  1. Assess data

  First off, take the time to become familiar with the Virginia Consumer Data Protection Act (VCDPA). Then, read the content from the ‘Who does the VCDPA apply to’ section of this article, and use this information to determine if the law applies to your organisation.

  How do you know if you reach the data subject threshold ? Easy. Use a web analytics platform like Matomo to see where your web visitors are, how many of them (from that specific region) are visiting your website and how many of them you’re collecting personal or sensitive data from.

  To do this in Matomo, simply open the dashboard, look at the “Locations” section and use the information on display to see how many Virginia residents are visiting your website.

  

  Using the dashboard will help you determine if the VCDPA applies to your company.

  2. Evaluate your privacy practices

  Review your existing privacy policies and practices and update them to comply with the VCDPA. Ensure your data collection practices protect the confidentiality, integrity and accessibility of your visitors.

  One way to do this is to automatically anonymise visitor IPs, which you can do in Matomo — in fact, the feature is automatically set to default. 

  

  Another great thing about IP anonymisation is that after a visitor leaves your website, any evidence of them ever visiting is gone, and such information cannot be tracked by anyone else. 

  3. Inform data subjects of their rights

  To ensure VCDPA compliance in your organisation, you must inform your data subjects of their rights, including their right to access their data, their right to transfer their data to another controller and their right to opt out of your data collection efforts.

  That last point is one of the most important, and to ensure that you’re ready to respond to consumer rights requests, you should prepare an opt-out form in advance. If a visitor wants to opt out from tracking, they’ll be able to do so quickly and easily. Not only will this help you be VCDPA compliant, but your visitors will also appreciate the fact that you take their privacy seriously.

  

  To create an opt-out form in Matomo, visit the privacy settings section (click on the cog icon in the top menu) and click on the “Users opt-out” menu item under the Privacy section. After creating the form, you can then customise and publish the form as a snippet of HTML code that you can place on the pages of your website.

  4. Review vendor contracts

  Depending on the nature of your organisation, you may have vendor contracts with a third-party business associate. These are individuals or organisations, separate from your own, that contribute to the successful delivery of your products and services.

  You may also engage with third parties that process the data you collect, as is the case for many website owners that use Google Analytics (to which there are many alternatives) to convert visitor data into insights. 

  Financial institutions, such as stock exchange companies, also rely on third-party data for trading. If this is the case for you, then you likely have a Data Processing Agreement (DPA) in place — a legally binding document between you (the data controller, who dictates how and why the collected data is used) and the data processor (who processes the data you provide to them).

  To ensure that your DPA is VCDPA compliant, make sure it contains the following items :

  • Definition of terms
  • Instructions for processing data
  • Limits of use (explain what all parties can and cannot do with the collected data)
  • Physical data security practices (e.g., potential risks, risk of harm and control measures)
  • Data subject rights
  • Consumer request policies (i.e., must respond within 45 days of receipt)
  • Privacy notices and policies

  5. Seek expert legal advice

  To ensure your organisation is fully VCDPA compliant, consider speaking to a data and privacy lawyer. They can help you better understand the specifics of the law, advise you on where you fall short of compliance and what you must do to become VCDPA compliant.

  Data privacy lawyers can also help you draft a meaningful privacy notice, which may be useful in modifying your existing DPAs or creating new ones. If needed, they can also advise you on areas of compliance with other state-specific data protection acts, such as the CCPA and newly released laws in Colorado, Connecticut and Utah.

  How does the VCDPA differ from the CCPA ?

  Although the VCDPA has many similarities to the CCPA, the two laws still have their own approach to applying the law. 

  Here’s a quick breakdown of the main differences that set these laws apart.

  Definition of a consumer

  Under the VCDPA, a consumer is a “natural person who is a Virginia resident acting in an individual or household context.” Meanwhile, under the CCPA, a consumer is a “natural person who is a California resident acting in an individual or household context.” However, the VCDPA omits people in employment contexts, while the CCPA doesn’t. Hence, organisations don’t need to consider employee data.

  Sale of personal data

  The VCDPA defines the “sale of personal data” as an exchange “for monetary consideration” by the data controller to a data processor or third party. This means that, under the VCDPA, an act is only considered a “sale of personal data” if there is monetary value attached to the transaction.

  This contrasts with the CCPA, where that law also counts “other valuable considerations” as a factor when determining if the sale of personal data has occurred.

  Right to opt out

  Just like the CCPA, the VCDPA clearly outlines that organisations must respond to a user request to opt out of tracking. However, unlike the CCPA, the VCDPA does not give organisations any exceptions to such a right. This means that, even if the organisation believes that the request is impractical or hard to pull off, it must comply with the request under any circumstances, even in instances of hardship.

  Ensure VCDPA compliance with Matomo

  The VCDPA, like many other data privacy laws in the US, is designed to enhance the rights of Virginia consumers who have their personal or sensitive data collected and processed. Fortunately, this is where platforms like Matomo can help.

  Matomo is a powerful web analytics platform that has built-in features to help you comply with the VCDPA. These include options like :

  • Cookie-less tracking
  • Creating consumer consent and opt-out forms
  • Giving consumers access to their personal data
