In one paragraph
Zuuun publishes practical security guides for people and small teams: what to do after a scam, how to lock down accounts and phones, and the IT basics a small business needs without an IT department. Every guide is written to be finished in one sitting, is checked against official documentation, and shows the date it was last verified.
Who writes Zuuun
I'm Héctor Ariel García Matute, Ariel for short. I'm an ICT engineer from Ecuador: I studied Information Technology Engineering at the Universidad Técnica de Machala (2018–2025), and I build software for a living.
Since 2022 I have run Single Seven, a one-person Android studio. I design, build and publish the apps myself on Google Play, which means working through Google Play's policy and compliance requirements, in-app advertising and billing, and the accounts and keys that a published app depends on. Since 2019 I have also built web, real-time and IoT projects, including services with token-based (JWT) authentication, a Raspberry Pi device controlled over MQTT, and multiplayer game servers. The code is public on GitHub.
Zuuun is where I write down, in plain English, the procedures I wish everyone had before something goes wrong: what to do after a scam call, how to recover an account, and which settings actually matter.
What I am, and what I am not
I am a software engineer, not a penetration tester or a certified security auditor. That is why every guide is built on official documentation from the companies and agencies involved (such as the FTC, CISA, the FBI, Google, Microsoft and Apple), says what was tested and when, and is corrected when a step changes. If a guide could not be tested, it says so.
Why this site exists
Most security advice online falls into two camps: vague tips ("use strong passwords") or long articles that end in a product pitch. Neither helps the person who just clicked a bad link, or the shop owner who is not sure whether their email is set up safely. Zuuun aims to be the page you can follow step by step, with a clear answer at the top and nothing you have to buy to make it work.
What you will find here
- Scams and fraud: how current scams work and what to do if one reached you.
- Accounts and passwords: two-step verification, passkeys, password managers and account recovery.
- Privacy: phone and browser settings, data brokers, and when a VPN actually helps.
- Small business security: checklists and setup guides for teams without IT staff.
- AI safety: voice-clone and deepfake scams, and how to use AI tools without leaking data.
How the guides are made
Each guide lists the devices, versions and sources it was checked against, and says plainly what was not tested. The full method, including how AI tools are and are not used, is on the How we test page. How the site makes money is explained in the editorial policy.
What Zuuun is not
- It is not a security company and does not sell security services.
- It does not publish paid reviews or accept free products in exchange for coverage.
- It is not a substitute for your bank, the police or a professional who can look at your specific situation.
