7 Best European iCloud Alternatives in 2026

Internxt is a Valencia-based zero-knowledge encrypted cloud storage platform where files are encrypted client-side before upload using post-quantum Kyber-512 + AES-256 cryptography, meaning not even Internxt can access your data. An open-source codebase and independent security audit by Securitum in 2024 provide external verification of every security claim.

Files sync across Windows, macOS, Linux, iOS, and Android via native apps. Sharing works through encrypted links that are password-protected and time-limited, while Internxt Send enables large-file transfers with zero provider access. A permanently free 1 GB plan requires no credit card, and lifetime payment options eliminate recurring subscription costs.

Key benefits:

• Zero-knowledge E2E encryption so Internxt cannot access files even under legal compulsion
• Post-quantum cryptography (Kyber-512 + AES-256) for future-proof data protection
• Open-source code independently audited by Securitum in 2024
• 1 GB permanently free with no credit card and no expiry
• Lifetime plans available as one-time payment with no recurring subscription
• Internxt Send for encrypted large-file transfers with expiring, password-protected links
• ISO 27001:2022 and HIPAA certified for enterprise and healthcare use cases

Headquartered in Valencia, Spain, Internxt processes all data under GDPR and EU data protection law. The platform holds ISO 27001:2022 and HIPAA certifications, stores all data in the EU, and was independently security-audited. Founded in 2020 by Fran Villalba Segarra, it offers the most rigorous open-source privacy credentials of any EU cloud storage provider.

Built for individuals, freelancers, and teams who want provably private cloud storage, because the code is open for anyone to verify, not just a privacy policy to trust.

Tresorit is a Swiss end-to-end encrypted cloud storage and file collaboration platform with a zero-knowledge architecture: files are encrypted on your device before upload, and only you and explicitly authorised recipients can ever decrypt them. It holds the broadest compliance portfolio of any EU cloud storage solution: GDPR, HIPAA, ISO 27001, SOC 2, TISAX, ITAR, NIS2, and DORA.

Teams share files through encrypted tresor folders with granular access controls, watermarking, and the ability to revoke shared links instantly. Tresorit Engage provides secure data rooms for client and partner collaboration, while an eDiscovery module helps legal and compliance teams locate and export documents for regulatory requests.

Key benefits:

• Zero-knowledge E2E encryption means even Tresorit cannot access your files
• Encrypted team folders with granular permissions and instant access revocation
• Secure external sharing with password-protected, time-limited links

Swiss law and GDPR govern all data handling, and the platform undergoes regular independent security audits with no U.S. entities involved in storage or processing.

Trusted by law firms, financial institutions, healthcare providers, and automotive manufacturers across Europe for provably secure file storage and external collaboration.

MemoFamille is a private photo and video album for one family, built so that grandparents can use it without help. Parents, grandparents, uncles and aunts join the same space with a family code, then share and comment on memories that would otherwise get lost in group chats. The app and website are in French only.

One subscription covers the whole family, with unlimited members, unlimited photos and videos of up to ten minutes. The apps run on iPhone and Android, and relatives who prefer a computer open the album in a web browser without installing anything. Notifications tell everyone when something new arrives, and a Méli-Mélo feed resurfaces older memories at random.

Key benefits:

• Family code access so only invited relatives see the album
• Designed for older users with a simple open, look and comment flow
• Unlimited members and photos on a single family subscription
• Videos up to ten minutes in the same feed as the photos
• Events and reactions to gather a birthday or holiday and talk about it in place
• No advertising in the album, as a stated commitment
• Free data export so the family keeps its archive if it leaves

MemoFamille is published by Yann Bronner, a sole trader registered in Mulhouse, France, since 2024. Photos, videos, the database and account data are hosted in France by OVHcloud, and audience measurement uses Umami on those same servers plus PostHog in the EU. Some supporting services are American: RevenueCat manages in-app subscriptions, Expo delivers push notifications, Sentry collects error reports and GrowthBook runs site tests, while Firebase Analytics and Google Ads measurement run only with consent given in the app.

After a 30-day trial with no card required, it costs €5.99 a month, or €59.88 a year (€4.99 a month).

It includes Proton Docs and Sheets for encrypted real-time document and spreadsheet collaboration.

Available on web, Windows, macOS, iOS, and Android, Proton Drive syncs files automatically via a desktop folder. 5 GB of free storage is included with every Proton account, with upgrades that bundle Mail, Calendar, VPN, and Pass. An open-source codebase allows independent cryptographic verification by any researcher.

Key benefits:

• Password-protected sharing with configurable expiry on shared links
• Automatic mobile photo backups with encrypted collaborative album sharing

The service is GDPR-compliant, holds ISO 27001 certification, and is audited by independent security researchers. Switzerland's constitutional privacy protections and absence of mandatory data retention laws provide a legal framework stronger than most EU alternatives.

Part of the Proton ecosystem trusted by over 100 million users worldwide, from journalists and activists to enterprises requiring sovereign data storage.

Office EU is a European cloud drive for households and small teams, and today its live product is EU Drive: 500 GB of storage per household with file sync and sharing, built on Nextcloud Hub and run as a managed service. Documents, email, calendar and chat are announced but not yet available.

EU Drive works in the browser and through desktop sync clients for Windows, macOS and Linux, plus mobile apps for iOS and Android. Files can be shared through password-protected links, access can be revoked later, and selected folders can be kept offline. The Basic plan costs 10 euros a month including VAT, with half off the first 12 months during the launch offer, and up to five extra users at 1 euro each.

Key benefits:

• 500 GB per household shared between up to six users on one plan
• Desktop sync clients for Windows, macOS and Linux, plus iOS and Android apps
• Password-protected sharing with links you can revoke if something was shared by mistake
• Encryption in transit and at rest, with optional end-to-end encryption for sensitive files
• Offline access to selected files that sync back when you reconnect
• Unmodified upstream Nextcloud releases under the AGPL licence

Office EU is operated by EUfforic Europe B.V., a Dutch private limited company registered in The Hague, the Netherlands. Its privacy policy states that all services and data run on Hetzner servers in Germany and Finland, that every sub-processor (including payments and newsletters) stores data inside the EU, and that no personal data is transferred outside the European Economic Area. The company is an official Nextcloud Gold partner.

Ideal for families who want a Google Drive or iCloud replacement without running a server.

Infomaniak kDrive combines cloud file storage and document collaboration with hosting in Switzerland. It is aimed at individuals and teams who want a shared place for photos, working files and office documents without defaulting to Google Drive or Dropbox. The useful distinction is the connection between storage and editing, rather than storage capacity alone.

Files can be accessed through the web and synchronised with desktop and mobile apps. OnlyOffice integration lets colleagues edit documents online, while sharing tools make it possible to distribute files without e-mail attachments. kDrive can also sit inside kSuite alongside Infomaniak's communication tools, although the available collaboration features depend on the selected offer.

Key benefits:

• File synchronisation keeps working documents accessible through desktop and mobile applications.
• Online office editing lets colleagues work on documents through the integrated OnlyOffice suite.
• Shared folders provide a common file space for team collaboration on eligible plans.
• Sharing tools distribute documents through links instead of repeated e-mail attachments.
• Free personal storage includes 15 GB of kDrive space through my kSuite.
• Swiss hosting keeps the service's storage infrastructure within Infomaniak's Swiss data centres.

Infomaniak Network SA is registered in Geneva, Switzerland. The company states that kDrive is developed and hosted in Switzerland, complies with the GDPR and Swiss nFADP, and uses its own data centres. That is a concrete European hosting choice, but it should not be read as a claim that ordinary collaborative files use end-to-end encryption.

The free my kSuite offer includes online OnlyOffice editing alongside its 15 GB drive. Standalone paid kDrive is advertised from CHF 4.99 per month with 3 TB, excluding VAT. Teams should compare standalone storage with kSuite's per-user offers and check which sharing and administration features their chosen package includes.
