Most privacy tools are either inconvenient or untrustworthy. Proton is the rare exception: a suite of products that actually make privacy the default, not a setting you have to find. We analysed Proton's privacy policy in depth and gave it an A — one of the highest scores in our dataset. Here's what that means in practice.

What Proton actually is

Proton started as a single encrypted email service, founded in 2014 by scientists who met at CERN in Geneva. It's now a full suite of products:

• Proton Mail — encrypted email, calendar, and contacts
• Proton VPN — a no-logs VPN with servers in 100+ countries
• Proton Drive — end-to-end encrypted cloud storage
• Proton Pass — an encrypted password manager

All of them are available under a single Proton account, with a free tier for each product and a paid bundle (Proton Unlimited) that unlocks everything.

Why the privacy is real, not just marketing

The difference between Proton and most "privacy-focused" products is architecture. Most services promise not to read your data. Proton can't read your data — technically. Their end-to-end encryption means your emails, files, passwords, and calendar events are encrypted on your device before they're ever sent to Proton's servers. Proton holds only ciphertext.

This matters in practice. In 2021, Swiss authorities compelled Proton to log the IP address of a climate activist. Proton complied — they had to, under Swiss law — but they had nothing else to hand over. No email content. No files. Just an IP address. The architectural constraint was real.

Key details from their privacy policy that we found meaningful:

• No permanent IP logs by default — IP addresses are not stored in relation to your account unless you enable optional authentication logging, which is off by default
• Account creation requires no personal data — you can sign up with no name, no phone number, no recovery email
• Self-hosted analytics — they built their own analytics tool rather than using Google Analytics; IP addresses are not retained
• Anonymous payments accepted — Bitcoin and cash are both options, meaning you can pay without any financial identity trail
• Swiss jurisdiction — Swiss law provides strong data protection, and is formally recognised as adequate under GDPR

We scored Proton 88/100 — the highest score we've given any mainstream consumer platform. The only reasons it isn't higher: policy change notifications are by date update only (no email to users), and there's some necessary metadata retention for anti-spam that can't be fully avoided.

Proton Mail vs Gmail

Gmail scored 26/100 in our analysis — grade D. The gap between the two is not marginal.

Gmail scans your email metadata to build advertising profiles. It shares data across the entire Google ecosystem. Your inbox informs what ads you see on YouTube and Search. The product is free because you and your data are the product.

Proton Mail's free tier is free because Proton Unlimited subscribers subsidise it — the same model as Wikipedia or Signal. There is no advertising product. There is no reason to mine your inbox.

The trade-off: Gmail is more convenient. It integrates with every other Google service, has better spam filtering trained on billions of emails, and more third-party app integrations. If you send a lot of email to non-Proton users, those messages leave Proton's servers in standard format — end-to-end encryption only applies between Proton users. The privacy advantage is in what Proton can't do to your data, not in making every email you send impenetrable.

Proton VPN vs the rest

The VPN market is full of companies with good marketing and ambiguous privacy practices. Proton VPN stands out on two counts.

First, their no-logs policy has been independently audited — multiple times, by external security firms, with published reports. Audited claims and unaudited claims are very different things.

Second, Proton VPN is open-source. Every client app (iOS, Android, Windows, macOS, Linux) has publicly readable code. You can verify that it does what it says. This is not true of most VPN providers.

Speeds are competitive with the major commercial VPN providers. The free tier is genuinely usable — no bandwidth limits, servers in three countries — which is unusual in the VPN space, where "free" usually means either severely restricted or data-harvesting.

Proton Pass

Password managers are a surprisingly neglected part of most people's privacy setup. Proton Pass launched in 2023 and is a genuine competitor to 1Password and Bitwarden.

Like everything else in the Proton suite, it's end-to-end encrypted and open-source. It includes email alias generation (similar to Apple's Hide My Email), which lets you create unique email addresses for every service you sign up to — so a data breach at one site can't cascade across your other accounts.

Who it's for

Proton is not for people who want zero friction. Migrating from Gmail involves export, import, and telling everyone your new address. The Proton Mail interface is good but not identical to what you're used to. Some integrations that work seamlessly with Google don't work with Proton, or require workarounds.

It's for people who have decided that the convenience of Google's ecosystem isn't worth what it costs in data. For journalists, lawyers, activists, or anyone whose communications are genuinely sensitive, it's arguably the right choice regardless of friction. For everyone else, it depends on how much you value not being the product.

Pricing

Each Proton product has a usable free tier. Proton Unlimited bundles everything — Mail (15 GB storage, custom domain support), VPN (all servers, 10 simultaneous connections), Drive (200 GB), Pass (unlimited), and Proton Scribe (the AI writing assistant) — for around €9.99/month, or less on an annual plan.

If you're already paying for a VPN and a password manager separately, the bundle often works out cheaper. If you're currently using Google One for storage, the comparison is also worth running.

The verdict

Proton is the closest thing we've found to a big-tech alternative that doesn't require you to compromise on either privacy or usability. It's not perfect — no service is — but the architecture is honest, the policy matches the pitch, and the business model doesn't depend on knowing everything about you.

We gave it the highest grade in our dataset because it earned it.
