  16 novembre 2016, par marcimat@… — Log

  Éviter lorsqu’il n’y a pas de compression JS/CSS activée, que le navigateur redemande les fichiers css et js du porte plume qui sont compilés par SPIP.
  On ajoute cache-client sur le cache de ces fichiers. C’est presque suffisant, mais il faut aussi les recalculer lorsqu’un plugin qui modifie les fichiers
  de porte-plume s’active ou se désactive. Du coup, on calcule un hash et un fond statique pour ces 2 fichiers, qui dépend du code variable de ces fichiers.
  Bon du coup on peut éviter quelques hits sur le serveur, mais la contrepartie, c’est qu’il faut calculer ces hash, parfois inutilement j’imagine, au calcul d’une page.
  À voir.

• 11 ways Piwik Analytics helps you to protect your visitors privacy

  11 janvier 2017, par InnoCraft — Community

  At Piwik and at InnoCraft, we think Privacy matters. From the beginning, Piwik has had a strong focus on privacy and ensures the privacy of your visitors and analytics data. As a result, Piwik has been recommended as a privacy-compliant analytics tool for example by the Independent Center for Privacy Protection in Germany (ULD) and by the Center for Data Privacy Protection in France (CNIL). In France, Piwik is the only web analytics tool that does not require Cookie Consent.

  Here are some ways how you can ensure your users and visitors privacy by using Piwik.

  1. You own the data

  Whether you host Piwik on premise yourself, managed on premise by InnoCraft, or whether you use our Piwik cloud, when you use Piwik, YOU keep control of your data and nobody else. This also means you can decide where your data should be located physically.

  2. Anonymized IP addresses

  For better privacy by default, Piwik will not record the full IP address of your visitors because otherwise the browsing history could be easily tracked across several days and even across websites within the same Piwik server. Some countries even require to anonymize the IP address, considered Personally Identifiable Information (PII).

  To change the IP anonymization settings go to “Administration > Privacy”. Optionally, you can use the full IP to still get for example accurate location data.

  

  3. Delete old visitor logs

  The visitor logs contain information all the collected raw data about every visitor and every action. You can configure Piwik to automatically delete logs from the database. When you delete old logs, only the real time and visitor log reports will no longer work for this old time period, all other aggregated reports will still work.

  For privacy reasons, we highly recommend that you keep the detailed Piwik logs for only 3 to 6 months and delete older log data. This has one other nice side effect : it will free significant database space, which will, in turn, slightly increase performance !

  

  4. Support Do Not Track preference

  Do Not Track enables users to opt out of any tracking by websites they do not visit, including analytics services, advertising networks, and social platforms. By default, Piwik respects users preference and will not track visitors which have specified “I do not want to be tracked” in their web browsers. Get more information about DoNotTrack.

  To make sure Do Not Track is respected, go to “Administration => Privacy”.

  5. Include an Opt-Out Feature on your website or app

  By embedding the Opt-Out feature in your website, you give your visitors the possibility to opt-out of the tracking. When you go to “Administration > Privacy”, you will be able to copy and paste an HTML Iframe code to embed the opt-out feature for example into your privacy policy page or in your ‘Legal’ page. Your users can then click on a link to opt-out.

  On the Piwik Marketplace there are also some plugins available to customize the Opt-Out experience. For example AjaxOptOut and CustomOptOut.

  

  6. Disable Live features

  The Real-Time, Visitor Log and Visitor Profile features give you insights into the tracked raw data by showing you details about every visitor and every action they performed. To protect the privacy of your visitors you may decide to prevent access to such features by disabling the “Live” plugin in “Administration => Plugins”. This way only aggregated reports will be shown in your Piwik.

  7. Disable fingerprinting across websites

  By default, when one of your visitors visits several of your websites, Piwik will create a fingerprint for this user that will be different across the websites to increase the visitors’ privacy. You can make sure that this feature is disabled by going to “Administration => Config file” and verifying that the value of “enable_fingerprinting_across_websites” is set to zero.

  8. Disable tracking cookies

  Piwik uses cookies to store some information about visitors between visits. In some countries, the legislation requires websites to provide a way for users to opt-out of all tracking, in particular tracking cookies. You can disable cookies by adding one line in the Piwik Javascript code.

  9. Custom development

  Piwik is an open platform that lets you extend and customize the tracking, the reporting and the Piwik user interface to your needs and to protect your visitors’ privacy the way you want or need it. Learn more in the Piwik Developer Zone. You may also have a look at our Piwik Marketplace where you can find several free and premium features to extend your Piwik.

  10. Transparency

  By default, all information and all collected data in your Piwik server are protected and nobody can access it. However, Piwik allows you to optionally make your collected data public and you can export any Piwik report including the whole dashboard to embed it into your website. This way you can show your users exactly which information you track. When you decide to make reports public, we do our best to protect privacy and automatically hide any Personally Identifiable Information such as the Visitor Profile and we make sure to not show any Visitor IP address and the Visitor ID.

  11. Privacy policy

  When you use Piwik to track your visitors, we recommend to update your Privacy Policy to explain how Piwik is used and what data it gathers. We provide a Privacy Policy template for Piwik users that you can copy on your site.

  Continuous privacy improvements

  We are always interested in improving the privacy. If you miss any feature or have an idea on how to improve the privacy, please let us know.
