Privacy at Hackdoku

You can always play without an account and without giving your name. We collect as little as possible.

Without an account

• Your progress is stored only in your own browser (localStorage). We cannot see it.
• On the server we keep a game with the puzzle, your time, which attempt it is and the number of hints and mistakes. We need this to check your solution. We delete it after 30 days.
• To prevent abuse we keep an unreadable code of your IP address that changes every day. We do not store your IP address itself.
• We use a necessary session cookie. No advertising and no measuring services from others.

Visitor statistics

As on the rest of asperity.nl, we anonymously track how the site is used: which pages and cases are viewed, started and solved, when, through which link you arrived, which browser you use and which network your internet connection belongs to. For this we use a cookie with a random number (asperity_vid, 1 year) to count individual visitors, and an unreadable code of your IP address. We do not link this to your name or your account.

Highscores

A place on the list is voluntary. You choose a nickname, which everyone can see. Do not use your real name. Scores without an account are deleted after 12 months. We can hide nicknames.

Email about new cases

Signing up is voluntary and intended for people aged 16 and up. We keep your email address, the language you chose and when you signed up and confirmed. You first get a confirmation email; without confirmation we delete your address after 30 days. Until you confirm, we also keep the daily-changing code of your IP address to prevent abuse. We use your address for emails about new cases and now and then something about Asperity's awareness training. We keep it until you unsubscribe through the link in every email, or email us. It then disappears from the list. Your email address is not linked to your scores or nickname. If you are logged in when you sign up, we only remember that you signed up, so that you no longer see the form. We do not store your address with your account.

Logging in with Google

Logging in is not required and is intended for people aged 16 and up. We then keep only an anonymous id that Google gives us, your best times and the nickname you choose yourself. No name, email address or photo. We only load Google's login script when you click Log in.

Under Account you can click Delete my data yourself. Your account, progress and nicknames then disappear immediately.

Fonts

The fonts on these pages come from Google Fonts. Google sees your IP address when they load.
