Data privacy is taken very serious on Anime Stats. Every data that is collected on this website is collected anonymously, tracing it back to you is almost impossible. However, here you'll find some information about what data is collected for what reason. If any questions arise, don't hesitate to ask. See Contact to get into contact.

This website uses Matomo Analytics (previously named Piwik). It is something like Google Analytics but able to run on the same server as the website it is used for. Matomo is the best choice when data privacy is of concern. Matomo collects and saves the following information but is not limited to:
  1. What: Your IP address and the time you access The IP address will be shortened so that it's impossible to identify you personally.
    For example: imagine your IP is, it'll be shortened to before it is saved.
    Why: To derive the country you came from (done from the shortened IP), that's what Matomo does, so it's (roughly) known where visitors come from.
    Matomo will give you a cookie with an ID that it is watching. This is an anonymous way of tracking you. That way you will be recognized as a revisiting user if you have such a cookie.
  2. What: Browser, incl. version, Operating System, screen resolution and plugins that you use.
    Why: These help to figure out what environment visitors use to access and what should be kept in mind to improve the site.
    Technically, it is possible to fingerprint your system with the used plugins. But since this data is only used on this project, it's negligible and not of any interest on here.
  3. What: Your referrer. That is a link where you came from unless removed or not set (Google removes the referrer per default, for example).
    Why: It helps greatly getting to know the audience and how this project is shared and discussed.
  4. What: Your engagement with this site in general, including but not limited to the anime you search in the menu, the anime you load the charts of, what archive data you load, how long you stay on this website, what genre you list, usage of the checkboxes below the charts, usage of the menu links and similar.
    Why: Basically to know how you use this site overall and what features are prioritized.
    I.e. if you just come by to take a short look at the last updates and go away within 20 seconds or if you take your time, strolling through somehow, using the site for 30minutes or more.
    This helps greatly to understand how visitors use, for how long on average and where improvements might be needed or features can be ignored.

That's pretty much it for Matomo. The server itself collects your IP as well in case errors occure (not necessarily visible errors on the website). But the provider Uberspace (German), a shared hoster where this website is hosted on, is pretty privacy sensitive as well, they shorten your last digits ( to before saving them to the error_log. The access_log is disabled by default.

For a number of legitimate reasons, for example but not limited to:

  1. To ensure the safety of the website in discovering potential security issues
  2. To be able to filter out evil bots visiting this website disguising as eligible users
  3. To ensure the website runs as smooth as possible for you and everyone else
  4. To be able to distinguish what features are more useful to you than others by analysing the usage of such features
  5. Some of the information is technically necessary, like your IP address to know where the data has to go to, or session cookies that belong to your browser preventing too many requests to the server
  6. When using the contact formular on the website your mail address for replies, your IP as well to prevent abuse
For now there's no definite end but there have been server changes that led to multiple wipes, the last was on 23rd June 2017.
Since the data is entirely anonymous and used to compare improvements and changes, it's prefered to keep it that way.

Except for aggregated data, no.

Aggregated data is a summary of data in an arbitrary timespan and category, not specifically revealing any data that you have contributed.

Yes, as long as it is about the data solely collected on this site and not CloudFlare.

Either use a browser plugin like Ghostery. Install and click the Ghostery icon in your browser and block Matomo Analytics (if it's not blocked by default). Or, alternatively, you can use your browser settings and let it send a so-called "Do Not Track" header. Most recent mobile and desktop browsers support this and some send it by default. This setting can be found in the respective privacy options of your browser.

As said, Matomo respects your privacy and looks for that DNT-header before tracking you. If it is set, you aren't tracked at all. No cookies needed.

In case you won't use DNT/plugins or can't, you can manually opt-out here by removing the checkmark:

Opt Out of Matomo

Technically you have multiple rights regarding your own data:

  1. Right to disclosure / right to transfer data to you: You can request information about and the data itself
  2. Right to correct: You can request the correction of incorrect data
  3. Right to deletion: You can request the deletion of your data
  4. Right of restriction: You can limit processing of your data
  5. Right of objection: You can object on the data collection and processing
  6. Right to change your mind regarding your agreement of collecting and processing data

Practically, as stated above, any data is anonymously collected. IPs are shortened, server logs are minimal and save shortened IPs anyway, the access_log is disabled to begin with. Even if you request information, deletion, correction, or the data itself - which is your right - it's impossible to specify what data that is as none of it can be tracked back at you.

Exception applies for mail correspondence. They are distinctive and can be dealt with as described above.

For objecting to the data collection and processing see Is it possible to avoid being tracked on this site? above.

A/S makes use of some third parties. In the following is a list of those used on this website.

Youtube API (Google)

A/S makes use of the Google Youtube API, the API is used client side, that means on your browser as soon as you click a Youtube image below the charts. As long as you don't click it, there's no interaction with Youtube whatsoever. If you do, the videos are embedded with a "youtube-nocookie" frame but Youtube still collects data.

In cases like that, please see the Privacy Policy of Google to find out more about their policy and what data they collect about you.
