Do internal annotations on user accounts fall under the GDPR? In a platform such as Stack Exchange or any other moderated forum-type site, in which specific moderators have access to account information that regular users don't, and in which said moderators may make annotations on an account for the purposes of helping moderation, is the GDPR relevant to said annotations in any way? "Annotation" here simply means any arbitrary text message a moderator or employee may attach to an account for future reference, e.g. to keep track of continued bad behaviour. Does the account holder have any rights to see said annotations or request their deletion or alteration? In practice that would be counter productive for the moderators as it would inhibit their ability to moderate the platform efficiently. Would any other sort of metadata, like say, encryption keys generated for and attached to the account, be subject to the same kind of disclosure? If not, why would it be different?
IANAL. (1) GDPR is certainly relevant. (2) This is certainly "personal data" under the definition in GDPR article 4. (3) Maintaining this data is probably lawful under article 6 sections 1(a) (consent) - provided that the Terms and Conditions of the site make clear that the user by signing up is consenting to this information being held (3) There is certainly an obligation under article 14 to disclose that the information exists, and to say how it used. (4) Article 15 says that data subjects are entitled to see the information and know what recipients or categories of recipient have access to the information (I don't know whether it's enough to just say "moderators", or whether the moderators need to be identified). (5) I can't see any reasons why the obligations under articles 16, 17, and 18 regarding rectification, erasure, and restriction of processing aren't relevant. This is exactly the kind of situation that GDPR is designed to address. If you're restricting the service available to particular users based on a record of their behaviour or on judgements made by moderators, then they absolutely have a right to know, and a right of redress.
The GDPR only require explicit (hard) consent if you use the cookie to store personal data. Given the conditions you cite, the data you store is not personal data, so this cookie does not require consent. In theory, someone having access to both session cookie and "analytics cookie" could relate the two, but that is highly non-trivial. You may have to do DPIA to demonstrate that this is non-trivial, or that you have mitigation in place to mitigate staff abusing such access. But provided things are as you say, the "analytics" cookie does not require consent.
GDPR is not a blanket ban on the handling of personal data. It is a set of guidelines when and how data may be processed and stored. Documenting the compliance with a deletion request is one of many purposes for which some data may be retained after a deletion request. Others would be past contractual obligations, legal documentation requirements, and even a balance of 'legitimate interests' of the processors and the data subjects. The processor might be able to argue that fraud/abuse prevention is such a legitimate interest. What if I want to create a service that does let users enter their friends' email addresses, and send those friends an email invitation to the service? Get a specialist lawyer on staff who can check your exact business processes. A web site like this cannot possibly give you a full explanation of the pitfalls.
To do so I used some images and Gifs which may be under copyright but since I don't earn money for myself and there is no company backing me I was hoping that there is some protection for private persons like me who just want to showcase the project. Sorry. If your website is public facing (i.e. not password protected and available only to family and close friends), you need to follow copyright law. There is no exception to copyright just because a project is run by an individual for non-commercial purposes. I am also insecure about the GDPR regulations since I give users the ability to create an account and try it out. Your profile says you're in the EU. Then you need to comply with the GDPR. Is there any way to protect me against greedy lawyers and companies? Could I write something like: "This website is a peace of art" and save myself with arguments like "artistic freedom" or "free speech"? Nope. A controversial website run by Peter Sunde had at one point a "free speech" disclaimer (similar to the one you propose) posted. However, Sunde did never use this defense in court: Finnish court slaps Peter Sunde with €350k fine. If he had shown up in court, I am pretty sure the court would have told him that such a disclaimer has no legal merit. The only protection that will make you completely safe is to adhere to the law.
IANAL, But the information commissioners office (UK) describe personal data as: (bolding mine) The GDPR applies to ‘personal data’ meaning any information relating to an identifiable person who can be directly or indirectly identified in particular by reference to an identifier. This definition provides for a wide range of personal identifiers to constitute personal data, including name, identification number, location data or online identifier, reflecting changes in technology and the way organisations collect information about people. https://ico.org.uk/for-organisations/guide-to-the-general-data-protection-regulation-gdpr/key-definitions/ So I would say that in your case it is personal information. In principle, regardless of if you can identify an individual, personal data is that which can be used to potentially identify an individual. For an extreme example of why this is important: Lets say your app sells AIDs medication. Can a hacker who got in and stole your database, be able to use that with information they stole elsewhere to identify people with AIDs and blackmail them, in a way that they wouldn't if you had not stored this identifier? Plus, if you want to err on the side of caution, there's no legal penalty for telling the user about non-personal information you store.
The "Contribution activity" is extracted from repositories hosted on Github. Looking at the privacy statement, Github considers itself as a hosting service for those repositories. See EU Directive 2000/31/EC Article 14 for the exact definition and conditions: Article 14 Hosting Where an information society service is provided that consists of the storage of information provided by a recipient of the service, Member States shall ensure that the service provider is not liable for the information stored at the request of a recipient of the service, on condition that: (a) the provider does not have actual knowledge of illegal activity or information and, as regards claims for damages, is not aware of facts or circumstances from which the illegal activity or information is apparent; or (b) the provider, upon obtaining such knowledge or awareness, acts expeditiously to remove or to disable access to the information. Paragraph 1 shall not apply when the recipient of the service is acting under the authority or the control of the provider. This Article shall not affect the possibility for a court or administrative authority, in accordance with Member States' legal systems, of requiring the service provider to terminate or prevent an infringement, nor does it affect the possibility for Member States of establishing procedures governing the removal or disabling of access to information. Article 2(4) GDPR defines that the GDPR does not apply (to Github) in this case This Regulation shall be without prejudice to the application of Directive 2000/31/EC, in particular of the liability rules of intermediary service providers in Articles 12 to 15 of that Directive. Extracting data from the repositories to create a nicely formatted contribution activity list, would still be considered hosting as defined at Directive 2000/31/EC, because Github does not (manually) redact or modify commits. So if you want to hide your contribution activity, you must delete the contributions. And you should not ask Github to do that, but ask the owners of the repositories. And they might have good reasons to deny your request. If an owner of a repository denies your request without a good reason, you can ask Github to do so. But Github would then probably deny that request, because they explain in their privacy statement that modifying the history is not possible: The email address you have supplied via your Git commit settings will always be associated with your commits in the Git system. If you chose to make your email address private, you should also update your Git commit settings. We are unable to change or delete data in the Git commit history — the Git software is designed to maintain a record — but we do enable you to control what information you put in that record. edit To further clarify why Article 14 of Directive 2000/31/EC applies, see case C-236/08 (Google v. Louis Vuitton) where the European Court of Justice clarifies the meaning of that article (ECLI:EU:C:2010:159): In that regard, it follows from recital 42 in the preamble to Directive 2000/31 that the exemptions from liability established in that directive cover only cases in which the activity of the information society service provider is ‘of a mere technical, automatic and passive nature’, which implies that that service provider ‘has neither knowledge of nor control over the information which is transmitted or stored’. Accordingly, in order to establish whether the liability of a referencing service provider may be limited under Article 14 of Directive 2000/31, it is necessary to examine whether the role played by that service provider is neutral, in the sense that its conduct is merely technical, automatic and passive, pointing to a lack of knowledge or control of the data which it stores. The way Github creates/shows the contribution activity is in my opinion technical, automatic and passive. That means it is not liable, and that implies that the GDPR does not directly apply, unless data is unlawful, and someone notifies Github of that: The restriction on liability set out in Article 14(1) of Directive 2000/31 applies to cases ‘[w]here an information society service is provided that consists of the storage of information provided by a recipient of the service’ and means that the provider of such a service cannot be held liable for the data which it has stored at the request of a recipient of that service unless that service provider, after having become aware, because of information supplied by an injured party or otherwise, of the unlawful nature of those data or of activities of that recipient, fails to act expeditiously to remove or to disable access to those data. Surely the GDPR might be the reason data is unlawful. But you need a reason, in particular based on Article 17 ("right to be forgotten"). For example if personal data of a 12 year old child is processed without permission of it's parent. Without such a reason the legitimate interest of the repository owner will probably prevail (who wants to keep the git history complete).
First of all, in a GDPR contest, the process described is not strong anonymization. It may be hard for an outsider to go from the stored record to any PII, it is much easier for an outsider to &quot;single out&quot; an individual. This means that given a known individual, one can determine whether that person is among those listed in the records, or can determine this to a significant degree of probability. For this only the algorithm and the rotating salts are needed, one need not break the hash. Note also that the GDPR specifies that if a person can be singled out with the assistance of the site operator the data is not considered anonymized. Thus this data needs a lawful basis under the GDPR, and the various other GDPR requirement all apply. However, even if the data were totally anonymized, and say just added to a count of users with this or that User Agent, the process of reading local data (including but not limited to cookies) itself requires informed consent, and so a cookie banner or other interaction with similar info under the e-Privacy directive (EPD). The EPD, being a directive and not a regulation, must be implemented by national laws, and the exact provisions in those laws may differ somewhat from country to country. But I believe that all of them require consent before any local data is read.
The GDPR has a fairly broad concept of personal data: any information that relates to an identifiable person. This is far more than directly identifiable information! The concept of identifiability is further explained in Recital 26: To determine whether a natural person is identifiable, account should be taken of all the means reasonably likely to be used, such as singling out, either by the controller or by another person to identify the natural person directly or indirectly. So indirectly linkable information can still be personal data. In your example, that ID can be easily re-identified with a particular person if you know who the secretary was between 2012 and 2014. It is quite likely that there are members in the club with this knowledge, or that this information can be gained from public sources like newspaper reports. Thus, you should assume that your member IDs are at most pseudonyms, but not anonymous. They are likely still personal data. However, it doesn't necessarily follow that you would have to erase everything. Art 17 comes with lots of caveats and exceptions. For example, if you are processing this personal data under a legitimate interest, and someone requests erasure, you might have overriding grounds to continue processing anyway. E.g. such a legitimate interest could involve security or auditability purposes. There might also be such a legitimate interest for keeping some history for the club, but there would have to be a decision based on the individual circumstances. Furthermore, you can of course retain data e.g. due to a legal obligation, or when this information is necessary for the establishment of or defence against legal claims. I understand your desire to keep some data around. Instead of asking “do I have to delete this?” it might be more productive to consider “under which legal basis can I keep this?”. I think you might have a legitimate interest, but you'd have to carry out a balancing test between the various interests and rights. A really problematic approach would be to hold on to de-identified data in the belief that it no longer were personal data. Such a belief is usually mistaken. True anonymization that meets the GDPR's definition is really hard, in particular because you would also have to prevent indirect identification, also by other actors than yourself. There are theoretical models that can help with anonymization, e.g. with k-anonymization methods you'd ensure that there are no unique records in the DB. But this can be tricky to apply correctly, so I'd recommend to only treat aggregate statistics as truly anonymous. In 2012, the ICO has published an anonymization code of practice (PDF). It is no longer up to date with the current legal environment (in particular since the GDPR has expanded the concept of identifiability), but it provides a good overview of both the difficulties of preventing re-identification and an overview of potential solutions.
