Frequently asked questions

Anyone from about 13 years old who wants to understand cybersecurity or learn to code, with no prior knowledge. Students, career changers and curious people use it.

C shows what the computer really does with memory and numbers, it is the language of operating systems and many security tools, and it explains attacks such as buffer overflows. The web-security lessons use JavaScript, because browsers run JavaScript.

No. The code editor runs your C or JavaScript inside a sealed part of the app with no internet access. Nothing you type there is sent anywhere.

It teaches how attacks work in order to defend against them, inside safe simulations. Testing real systems without the owner's written permission is illegal in most countries, including Algeria, and the lessons say so clearly.

No app can: Android does not let ordinary apps change security settings, and that protects you. The app reads what it is allowed to read (screen lock, security update date, developer options, USB debugging, VPN), tells you what to fix, and opens the right settings page.

Elite is the one plan, $4 a month or $40 a year: all 16 houses and their exams, real protection steps in every house, 200 AI answers a day, 200 coins a month and no ads. See pricing.

On the website, through Lemon Squeezy's secure checkout. You get a licence key by email and paste it in the app (Store > Have a code?). We never see your card.

A learning reward inside the app. You earn them for right answers, finished lessons and solved code, and spend them on new lessons, retries, AI answers and freezes. They have no cash value. A wrong answer never costs a coin.

A freeze keeps your streak alive on a day you cannot study. Use one by hand from your profile, or keep it: if you miss a day, one is used by itself.

Yes: once per customer, within 14 days of buying, no questions asked. See the refund policy.

No. You can learn as a guest. An account keeps your coins and purchases when you change phone.

In the app: Settings > Account > Delete account. If you no longer have the app, see delete your account.

The AI coach and summaries use Google's Gemini, only after you agree. What you type is sent to Google to get the answer. Never type passwords, codes or personal details. You can turn cloud AI off at any time.

Google Play if you have it: it updates by itself. The APK is the same app; download it only from cybersecprotocol.app and check its fingerprint on the download page.

Android 8.0 or newer. The 3D world needs a phone with OpenGL ES 3.0, which almost every phone from the last eight years has; there is a simple list view for older phones.
