Privacy Policy

This policy explains what information Another Brick in the SILO collects, why, and what happens to it.

We only collect what is needed to run the CTF and award prizes. We do not sell your information or use it for advertising.

1. What we collect

• Account details: your username, email address and password. Passwords are stored in a hashed form, never in plain text.
• Registration choices: whether you are an Australian resident currently residing in Australia, and whether you want e2 Cyber to contact you.
• Optional profile details: affiliation, website and country, if you add them.
• Activity: challenge attempts, flag submissions, solves and scores.
• Technical data: your IP address and basic request logs, used for security and to detect cheating.

2. Why we collect it

• To create your account and let you take part.
• To run the scoreboard and work out results.
• To check prize eligibility and contact winners.
• To keep the event fair and secure.

3. What is public

Your username, score, solves and any optional profile details you add are shown publicly on this website. Your email address and registration choices are never shown publicly.

4. Who we share it with

• e2 Cyber: only if you opt in to be contacted when registering. If you do not opt in, e2 Cyber does not receive your registration details.
• Prize delivery: a winner's name and contact details may be shared with the partner providing their prize.
• Hosting: this website and its media files run on Amazon Web Services.
• Fonts: fonts are loaded from Google Fonts, which can see your IP address when they load.

We do not share your information with anyone else unless the law requires it.

5. Your browser

This website stores a few small preferences in your browser, such as whether audio is on. These stay on your device and are not used to track you.

6. How long we keep it

We keep account and activity data while the CTF platform runs, so results stay available. Prize eligibility details are deleted once prizes have been awarded.

7. Your choices

You can ask us to correct or delete your account and data at any time through the official event channels.

8. Changes

We may update this policy. The version on this page is the one that applies.
