For You All it is important to know, what personal user's information this site collects.
We are glad to tell that we store very few of it (close to zero, really)!
We respect your privacy and don't want to store personal data which we don't need. This also is an attempt to satisfy GDPR regulations (and similar regulations effective in countries outside EU).
Let's explain in details:
If you register using Gmail (Google) account, this site only keeps respective gmail ID (some long number,
it is public but not generally visible on gmail). E.g. it works so - our site directs you to google
login form, you login to google - and google brings you back to the site, and "tells" us
that google knows you and we should trust you.
If you register with GitHub or Facebook, it works the same way - we are only given your technical ID (still public)
by these sites, which allow to distinguish you from other users.
In all these cases our site also may receive your "visible name" (as configured in Gmail, Github or Facebook) and copy it to your account here - but you can change it in settings page (and of course this needs not be real personal data anyway).
If instead you register with username and password pair, of course this username may be related or not
related to your real name - it's your choice. Thus it is not personal data either (even if you use
username like john_doe no one can tell whether it is your name or not).
Passwords are not stored for such accounts. Instead we keep their hashes. Hash is like a footprint - it is possible to compare two persons by their footprints, but it is not possible to tell how person looks having only footprint. So we can compare hash of the password you enter every time you log in, but if database is hacked, hacker can not steal passwords from it.
We also ask for email for such accounts, to allow recovering if password is forgotten. However E-mails are not stored either. We similarly keep only its hash, along with first symbol and domain (so you can recollect which email you configured). When account recovery is needed, we shall re-ask you e-mail, compare its hash and if it is ok, then send recovery letter.
Note that you may put few words about yourself at your profile page - and similarly you may share your story at forum. Generally people doesn't write sensitive data here, though some put links to social network profiles or emails. It is your choice, and you can remove text from profile at any time (but usually not from forum!) - however remember that public pages are routinely copied by 3-rd party resources - e.g. search engines and "wayback machine".
Website tries to guess your country by IP and set this in profile, but you can change it to anything,
to represent your patriotic feeling etc. There is also Unknown choice available.
IPs from which you access web-site may be routinely logged by the site or web-server, but this is public data and more about your internet provider rather than yourself and mainly is saved to help investigate rare cases of account misuse etc.
We don't us any 3-rd party Ads currently, which could collect your browsing information.
We don't send any e-mails unless user explicitly requests it (e.g. for account recovery) - anyway as we prefer not to store addresses we don't know where to send them :)
Web-site uses Google Analytics for usage statistics - some anonymous / depersonified data (like browser type or country where user came from) is collected by this service (it is the same with most sites on the web, however). We don't store this data (really website even doesn't receive it - instead your browser just sends requests directly to google and google counts them). Such data may be forged by your browser if you want, though generally there is no sense in this :)
Deleting personal data
As explained above, minimum to zero personal data are stored by this site, depending on your login type. Most of them you can delete yourself (e.g. if your had your visible name similar to your real name, but do not want it anymore - you can change it to something random yourself).
If you want to remove some data to which you have no direct access - just raise the issue at forum (or contact admin directly if you prefer).
That's all. Hopefully you now understand better our approach - store less and be happy :)
