You're fed up with big data companies?

You may ask yourself: What happens with my Digital Footprint?

Let’s Take YouTube, as an example.
How do you pay out the Creators? 

Selling your Data for "Better" Advertisement
85%
Premium Subscriptions
10%
Channel Memberships, Donations
5%

YouTube doesn’t sell your data – it sells access to your attention.

What your digital footprint includes

  • What you watch, like, comment, search
  • Device info, IP address, location
  • Time spent on videos, scrolling behavior
  • Subscriptions, playlist activity 
  • Interaction with ads (clicks, views, skips)

Risks of your Digital Footprint

🔒Privacy Loss:

YouTube knows a lot about your behavior, preferences and habits.

🧠Manipulation:

Algorithms can shape what you see, think, or buy.

🎯Hyper-targeting:

You may be shown ads so tailored they feel invasive.

🎥Permanent record:

Unless “deleted”, your data remains on Google’s servers indefinitely.

⚖️Profiling bias:

You may be miscategorized or limited by assumptions from your behavior. E.G. China (Social Credit System)

Time to Rethink Your Digital Life

  • Your phone leaks data 24/7 – unless it’s built to protect you.
  • For people who value their privacy, this is not optional
  • Public clouds and default OS are not your allies.
GrapheneOS

Why GrapheneOS?

Open source means transparency – the code of GrapheneOS is public and anyone can read it, unlike Apple and partially Android. Unlike these 2 big tech vendors, there are no hidden trackers or black boxes.

Why it matters:

  • You’re not forced to trust a corporation – you can verify.
  • Security issues are found and fixed faster.
  • No ads, no profiling, no silent data collection.

GrapheneOS regularly releases security patches – often faster than Google’s own Pixel firmware. You stay protected without waiting on vendors or dealing with carriers.

Hardened Security (Sandboxed everything) 

Minimal Tracking – or none at all

Open Source & Audited

No Google Play Services (unless you choose) 

Every app in GrapheneOS runs in a strict sandbox – meaning it has zero access to your data unless you explicitly allow it.

Even if you choose to install Google Play Services, they run fully sandboxed as regular apps – they can’t spy on you or your files. It depends on your Apps; some may need the Play Services, but there are ways to do it right.

Benefits of Sandboxing:

  • Stops apps from reading your photos, messages, or contacts.
  • Prevents background tracking and microphone access,
  • Keeps your private life truly private – by design.
  • Privacy-conscious individuals
  • Business owners & executives
  • Journalists & public figures
  • Tech-savvy users who want more control

    About Me

    "I believe privacy is a human right - 
    not a luxury."

    Hi, I’m Linus Kaufmann, a privacy-focused IT nerd based in Zug.

    I’ve been fascinated by technology and digital systems for as long as I can remember.
    Over the Years, that curiosity evolved into a deep passion for open-source software, system security,
    and helping people take back control of their digital lives.

    I now support individuals, entrepreneurs, and public figures who want to stop relying on Big Tech —
    and instead choose freedom, privacy, and control.

    My Background / Expertise

    I’ve worked in IT for over 4 years and recently completed my degree as a Platform Developer. During this time, I’ve gained deeper knowledge in:

    • ✅ System security and mobile OS hardening

    • ✅ Linux, self-hosted cloud tools (Nextcloud, Synology, Mail)

    • ✅ Customer support and personal tech coaching

    • ✅ General web and app development 

    My focus shifted to privacy and security after I realized how silently and aggressively our personal data is collected — and how few options most people have to escape it.

    Today, I offer tailored solutions to anyone who wants to protect their data without giving up convenience. I also work with a trusted Swiss IT partner to provide secure, local hosting and privacy-respecting services — from private clouds to secure communication.
