Gmail: 1.5 billion users, zero privacy
Gmail has become the default email for over 1.5 billion people worldwide. Free, powerful, integrated into the entire Google ecosystem, it seems flawless. But this apparent free service hides an exorbitant cost: your personal data.
Google's business model: you are the product
Google's business model relies on targeted advertising, which accounts for the overwhelming majority of its revenue. To serve relevant ads, Google builds detailed profiles of its users by analyzing their behaviors: searches, location, videos watched, and of course, emails.
Although Google officially ended the scanning of Gmail emails for advertising personalization in 2017 (after years of controversy), the company continues to massively collect metadata: who writes to you, when, how often, from which IP address, and what links you click on. This metadata alone allows for a remarkably precise picture of your social, professional, and intimate life.
AI enters the scene: your emails to train Gemini
In July 2023, Google silently updated its privacy policy to add a crucial mention: the data collected from users — including Gmail content — can now be used to train its artificial intelligence models, including Gemini.
This update went almost unnoticed by the public, yet it changes everything. Your personal emails, your professional conversations, your receipts, your medical appointment confirmations — all this flow of information can now serve as raw material to improve Google's AI products. And contrary to what one might think, there is no simple and transparent mechanism to oppose it.
"Google may use information we collect from all our services to – among other things – train Google's AI models and develop new products and features."
— Google Privacy Policy, updated July 2023
The American monopoly and illegality recognized by the courts
In August 2024, U.S. federal judge Amit Mehta issued a historic ruling: Google is an illegal monopoly in the field of online search. The court concluded that the company had maintained its dominant position through anti-competitive practices, including paying billions of dollars to Apple, Samsung, and others to make Google the default search engine.
This ruling raises a fundamental question for Gmail users: can we continue to trust all our communications to a company found guilty of abusing its dominant position?
The problem goes beyond just the search engine. Google controls an overwhelming share of the global email infrastructure. According to various estimates, over 30% of all global emails pass through Google's servers. This extreme concentration creates a single point of failure and gives a single American entity unprecedented surveillance power on a global scale.
Digital sovereignty at stake
Beyond monopoly issues, Gmail's hegemony poses a problem of digital sovereignty. All of Google's servers are subject to U.S. law, notably the Cloud Act and the FISA (Foreign Intelligence Surveillance Act). These laws allow U.S. authorities to access data stored by American tech companies, even if that data is hosted abroad.
For a French or European citizen, this means that their emails can be accessed by U.S. intelligence agencies without their knowledge, and without the European legal framework (GDPR) being able to effectively oppose it.
Serious alternatives that exist
Fortunately, several services offer real privacy protection:
| Service | Country | Encryption | Model |
|---|---|---|---|
| Proton Mail | Switzerland | End-to-end, zero-access | Freemium |
| Tuta (formerly Tutanota) | Germany | Complete end-to-end (including subjects) | Freemium |
| Posteo | Germany | At-rest encryption, total anonymity | Paid (1 €/month) |
| Fastmail | Australia | No scanning, no ads | Paid (3 $/month) |
| StartMail | Netherlands | Integrated PGP, unlimited aliases | Paid (5 $/month) |
Proton Mail: the most well-known choice
Based in Switzerland, Proton Mail benefits from one of the world's most protective laws regarding privacy. Its zero-access encryption means that even Proton cannot read your emails. The service offers a free plan sufficient for personal use.
Tuta: the most radical
Formerly Tutanota, this German service encrypts everything, including subject lines and contacts. It offers open-source native applications for all operating systems and requires no personal information upon signing up.
Posteo: ethics and anonymity
For just 1 € per month, Posteo offers an email service without ads, no tracking, powered by green energy, and even accepting cash payments by mail to preserve total anonymity. An ideal choice for those concerned about their ecological footprint and privacy.
Conclusion: convenience has a price
Gmail is convenient. But this convenience comes at the cost of your privacy, the security of your personal data, and your digital independence in the face of a monopoly recognized as illegal by the courts. In a world where AI consumes more and more personal data to train, where mass surveillance is intensifying, and where the concentration of technological power has never been so extreme, leaving Gmail is no longer a paranoid stance — it is a digital responsibility act.
The transition takes some time and effort, but the tools exist. And they are good.
