Euria Privacy Review for Solo Freelancers: A Plain-English Verdict

If you handle client contracts, financial spreadsheets, or confidential correspondence, the AI tool you paste them into matters as much as the cloud you store them on. Most freelancers default to ChatGPT, Claude, or Gemini and then quietly hope the policy reads the way they remember. Euria, the Swiss-hosted assistant launched by Infomaniak in December 2025, takes a sharply different posture: data processed only in Switzerland, no AI training on user content, and an ephemeral mode where exchanges are never stored. The question is not whether the marketing is appealing — it is. The question is whether the posture, as written, actually holds up for paid client work. Short answer: for most solo freelancers, Euria is the safest mainstream option I’ve found this year. Long answer below, sourced from the policy text itself and grounded in how we evaluate AI tools.

What Euria does with your data

Per Infomaniak’s announcement of Euria (retrieved 2026-06-02) and the company’s data confidentiality policy (retrieved 2026-06-02), Euria is built on a foundation model operated end-to-end inside Infomaniak’s Swiss data centers. Three claims sit at the center of the privacy posture: requests are processed exclusively in Switzerland, no third-party providers receive the data, and content shared with Euria is not used to train AI models or build user profiles.

The retention picture is the unusual part. By default, conversations are stored in your account so you can return to them — standard behavior. But Euria also offers what Infomaniak calls an ephemeral mode: when active, exchanges are not stored on the server and cannot be recovered later, including by Infomaniak itself. That last clause is the meaningful one. Most vendors say “we delete on request”; Euria’s framing is closer to “we never wrote it down”. For freelancers used to scrubbing chat history manually, this is a structural difference, not a setting toggle.

Encryption is applied to discussions in transit and at rest within Infomaniak’s infrastructure (per the announcement page). The vendor also operates under Swiss data protection law (FADP) and aligns with GDPR, with Infomaniak acting as the data controller for service-level metadata and as a processor for content the user submits. Audit-trail wise, Infomaniak publishes its data center locations (Switzerland), confirms no transfer abroad, and runs entirely on renewable energy with waste heat recovery — relevant for green-procurement clauses some EU public-sector clients require.

What Euria does collect: the same operational metadata any SaaS keeps — account info, billing, IP-derived session data, usage logs. None of it, per the policy as written, is sold to third parties or routed to advertising networks. Compared to the default behavior of US-based mainstream assistants, the surface area exposed to training pipelines is materially smaller.

One detail worth highlighting because most reviews bury it: Infomaniak is a privately-held Swiss company whose founder transferred majority voting rights to the Infomaniak Foundation in May 2026 — a Swiss public-interest foundation operating under Geneva cantonal supervision (per the company’s foundation announcement, retrieved 2026-06-02). This is the kind of corporate-structure detail that does not affect any single conversation with Euria, but it does affect long-horizon questions like “will this vendor get acquired by a US adtech buyer next year and quietly rewrite the policy?”. Foundation-controlled means the answer is structurally no. For freelancers signing 3-year retainers with privacy-conscious clients, that long-horizon stability is a material factor that ChatGPT, Claude, and Gemini cannot match on the same axis.

What this means for solo freelancers

Three concrete scenarios are worth thinking through before you migrate any workflow.

Scenario 1: you’re a copywriter pasting a client’s product roadmap into a chat to draft launch emails. With ChatGPT or Gemini, that roadmap can end up in training corpora depending on your account settings and the vendor’s enterprise tier. With Euria in default mode, it stays in your conversation history but is not used for model training. With Euria in ephemeral mode, it leaves no trace once the session ends. For NDA-bound work, ephemeral mode is the configuration that matches the legal posture you’ve signed.

Scenario 2: you’re an accountant uploading anonymized but reconstructable client P&L spreadsheets to ask for variance analysis. “Anonymized” is doing a lot of work in that sentence. Any AI that retains those uploads — even just for “service improvement” — carries a re-identification risk. Euria’s published posture: processing happens in Switzerland, files are not retained for training, and the data does not cross borders. Based on the policy as written, this carries materially less downstream risk than processing the same file through a US-hosted vendor whose enterprise tier you don’t have access to as a solo.

Scenario 3: you’re a consultant subject to a client’s GDPR data-processing addendum requiring EU/EEA-only processing. Switzerland is not in the EU but holds an adequacy decision from the European Commission, meaning data transfers between EU/EEA and Switzerland are recognized as protected. Based on the policy as written, Euria’s Swiss-only processing footprint is workable for most GDPR controller-processor arrangements. It is not a substitute for signing your own DPA with Infomaniak — that is still required for paid commercial work — but the operational posture matches what GDPR-conscious clients are usually asking for.

One caveat worth naming: Euria is new. The published posture is strong, but there is no breach history yet because there is no operating history. For high-stakes legal or medical work, treat the first 12 months as a probationary period — use it, log incidents, but maintain a parallel manual workflow for the most sensitive cases.

A second caveat that affects pricing math: Euria sits inside Infomaniak’s broader kSuite ecosystem. The free tier exists, but freelancers who want the full feature set typically end up on kSuite or kSuite Pro for the mail, drive, and shared-workspace pieces. That means the privacy gain comes with a soft migration cost if you’re currently on Google Workspace or Microsoft 365. Budget a weekend of mailbox migration before you commit. The policy posture is the win; the operational lift is the cost. Both are real.

How to use it safely

The settings that matter, in priority order:

• Default to ephemeral mode for any session containing client identifiers. Toggle it before the first message — Euria stores nothing on the server once ephemeral is active. Reserve standard mode for personal drafts and learning sessions where conversation history is genuinely useful.
• Redact names and identifiers anyway. Belt and suspenders. Replace “Acme Corp Q3 revenue” with “Client A Q3 revenue” before paste. Even with Euria’s posture, minimizing what you send is always the right default.
• Use a dedicated Infomaniak account for client work. Keep personal experimentation separated. If a client asks for an audit trail of which tools touched their data, a clean account makes that conversation 90% easier.
• Sign a DPA before paid commercial use. Infomaniak provides a Data Protection Agreement on request — get it on file before the first paid project, not after. Two-page document, takes 10 minutes.
• Verify the policy snapshot quarterly. Policies change. Bookmark infomaniak.com/en/legal/confidentiality-policy and re-read the retention and training-data sections every 90 days. If anything material shifts, reassess.
• Don’t paste material you’d refuse to email. The strongest privacy policy in the world doesn’t protect you from your own oversharing. Euria is a tool, not absolution.

Privacy-friendlier alternatives

Euria is strong, but it’s not the only option. The right stack depends on what you’re already paying for and what you need beyond a chatbot.

Proton Scribe and Proton AI assistants — built into the Proton ecosystem (Mail, Drive, Pass). End-to-end encryption is core to the architecture, not bolted on. Best for freelancers already using Proton Mail and Proton Drive who want AI-assisted writing and summarization without leaving the encrypted environment. Pricing: included in Proton Unlimited (~€10/month) or Mail Plus (~€4/month). Target user: privacy-first freelancers running their entire client communication stack through Proton.

Le Chat by Mistral (Pro tier) — French foundation-model vendor, EU-hosted, with enterprise data residency commitments. Strong on European data sovereignty and increasingly mature on document-handling features. Pricing: Le Chat Pro at €14.99/month. Target user: EU-based consultants who want a US-equivalent feature set (image analysis, web search, document interpretation) without the US-hosting question mark.

YubiKey 5 NFC — not an AI tool, but the missing piece for any of the above. If you’re moving sensitive client work through any cloud AI, hardware-based two-factor authentication on the account holding it is non-negotiable. Around $55, lasts years, plugs into USB-A or NFC for mobile. Set this up before you upload the first client file, not after. Hardware path matters more than which AI you pick.

What to pair with Euria, not replace it: a privacy-respecting password manager (1Password or Bitwarden) and an EU-based VPN if your client work requires geographic data-residency proofs (NordVPN for the meshnet feature, or Mullvad for the strictest no-logs posture). The combination — Swiss-hosted AI + EU-friendly password vault + EU-routable VPN — gets you to a privacy posture that solo freelancers handling sensitive client work could not assemble from US-only tools at any price two years ago.

FAQ

Is Euria GDPR-friendly for EU freelancers?

Based on the policy as written, Euria operates exclusively from Swiss data centers, which benefit from a European Commission adequacy decision recognizing Switzerland as providing equivalent data protection. This makes Euria workable under most GDPR controller-processor arrangements for EU-based freelancers. You still need to sign a DPA with Infomaniak before processing client data commercially — adequacy decisions cover the transfer, not the contractual relationship.

Does Euria train on my prompts or uploaded files?

No, per Infomaniak’s announcement and confidentiality policy as of 2026-06-02. The vendor states that user content is not used to train AI models, build user profiles, or feed third-party systems. This is a stronger default than most US-based assistants, which typically require an enterprise tier or an explicit opt-out toggle to reach the same posture.

Can I use Euria for HIPAA-regulated client data?

HIPAA is a US-specific framework, and Euria has not, to my knowledge, published a HIPAA Business Associate Agreement. If you handle US healthcare data, Euria is not the right tool — you need a vendor with a signed BAA. For non-US health-adjacent work where local data protection law applies, Euria’s Swiss-only posture is workable, but always check with the client’s compliance officer before processing identifiable health information.

What happens to my chats if I close my Infomaniak account?

Per Infomaniak’s confidentiality policy as written, personal data is retained only for the period necessary to provide the service. On account closure, stored content is deleted in line with that retention window. For chats started in ephemeral mode, nothing was stored on the server in the first place. For maximum certainty before closing, export anything you need and verify deletion via the account dashboard.

Is Euria a complete replacement for ChatGPT or Claude?

Feature parity is improving but not complete. Euria handles voice, image analysis, document interpretation (PDF, Word, Excel), web search, and translation at launch. What it doesn’t yet have at the maturity level of OpenAI or Anthropic: a deep ecosystem of plugins, custom GPTs, or third-party MCP integrations. For text, document, and conversation workflows, it’s directly competitive. For complex multi-tool agentic workflows, US assistants are still ahead.

How does Euria’s ephemeral mode actually work?

Per the Euria announcement page (retrieved 2026-06-02), ephemeral mode means the exchange is not stored on the server, leaves no trace, and cannot be recovered by any means including by Infomaniak itself. Functionally, you toggle it on before starting a sensitive conversation; the session works normally; when you close it, there is no chat history to revisit. The trade-off is convenience — you lose the ability to scroll back later — in exchange for a structural guarantee, not a deletion promise.
