Written by human for humans

Cloud storage has become an essential part of our lives today, offering convenience, accessibility, and secure storage for large amounts of data. While it provides many benefits, it’s important to be mindful of potential risks like data breaches or unauthorized access. Choosing a reliable and secure cloud storage provider is crucial to ensuring the safety of your files.

Koofr, a Slovenian privacy-oriented cloud storage provider, has been in the market for over 12 years and prioritizes privacy and data protection. With servers located in the European Union, Koofr ensures compliance with strict EU data privacy regulations, providing peace of mind regarding the security and privacy of your data.

How safe are my files on Koofr?


Koofr, a reliable European cloud storage provider, is committed to keeping your files safe using a variety of security technologies. Every file transfer is secured with Secure Sockets Layer (SSL) / Transport Layer Security (TLS) encryption from the moment the transfer from your device to Koofr begins. In plain English, this means no one can see the content of your files while they are being transferred to Koofr's servers, not even a snooping tech guy operating a public Wi-Fi in your local coffee shop.

Welcome to Koofr. Because privacy matters.

Once your files reach our servers, we apply server-side encryption for additional protection. This ensures a good balance between keeping files secure and being able to consume them in all modern ways (like playing videos inside the browser, editing Office documents or scrolling through thumbnails on your phone).

Koofr is fully GPDR compliant

All files on Koofr are stored in secure data centres located within the European Union, ensuring compliance with strict EU data protection regulations. Koofr is fully GDPR-compliant, adhering to the highest standards of data protection and privacy as required by EU law. This ensures your data is handled responsibly, transparently, and securely. GDPR compliance is not just a legal requirement but a reflection of our commitment to safeguarding your privacy and the security of your files.

To safeguard against data loss, Koofr’s system ensures each file is stored in at least three separate physical locations. Additionally, metadata and file content are stored on separate layers, often on different servers, maximizing file safety. All data is stored in ISO 27001-certified data centres in Germany, powered by 100% renewable hydropower energy, further enhancing security and sustainability.

We do not use third-party tracking tools such as Google Analytics and do not place cookies in your browser, except for the one necessary to keep you logged into the application. If you do not log in, Koofr’s website operates entirely without cookies, ensuring a truly private browsing experience.

We consistently review and reassess our data collection processes to ensure we only collect what is absolutely necessary. This focus on minimizing data use guarantees that your information is protected and handled with the utmost care.

At Koofr, your email is solely used as your username within our application. We will never send marketing materials or newsletters to your address. The only emails you may receive are important service notifications, such as account expiration alerts, policy updates, invoices for paid upgrades, or specific automatic notifications you’ve requested, like when someone uploads files to your account. We will never sell or share your data with advertisers, tracking companies, or any third parties, except those directly involved in providing our services, such as payment processors and accounting partners.

Data Deletion Policy - Personal data

When you request the removal of your personal data, we ensure it is completely and irreversibly deleted from our servers within 30 days. This process is non-recoverable, meaning your data is permanently erased. If you later decide to create a new account with the same email, it will have no association with any previous data, as all prior information will have been securely destroyed.

Personal data is retained only for the duration required by law or as needed to provide the service. Once these periods expire, your data is securely and permanently deleted. Additionally, in compliance with GDPR, Koofr automatically deletes accounts that have been inactive for over two years, further ensuring that unnecessary data is not retained.

Deleting files - No Hidden Copies

When files are deleted from the Deleted files in your Koofr account, they are permanently removed, with no hidden copies retained on Koofr's servers. This transparent approach ensures you have complete control over your data.

No AI training on user data

It is essential to take into account the AI privacy concerns, ensuring that personal data remains protected and is used only for the purposes to which users have consented. We are firmly committed to never selling, sharing, or utilising your data for AI training purposes.

Enhanced Security Features

Koofr offers two-factor authentication (2FA) to provide an added layer of security for your account. By enabling 2FA, you can ensure that even if someone gains access to your password, they will not be able to access your account without the second verification step.

How Two-Factor Authentication Improves Your Online Security

At Koofr, we prioritize the safety and privacy of your files, ensuring they are protected with advanced encryption, secure EU-based data centres, and strict adherence to GDPR. With no tracking, no ads, and no unnecessary data collection, we offer a secure and private cloud storage solution you can trust.
