Terms of Service

Terms and conditions for using SafeDisk

Last Updated: April 11, 2026

These Terms of Service ("Terms," "Agreement") constitute a legally binding agreement between you ("User," "you," "your") and Afina Systems Spółka z ograniczoną odpowiedzialnością (KRS: 0000884244, NIP: 5252852337, REGON: 388239950, VAT ID: PL5252852337), a company organized under the laws of the Republic of Poland, with its registered office at ul. Senatorska 2, 00-075 Warszawa, Poland ("SafeDisk," "Company," "we," "us," "our"), governing your access to and use of the SafeDisk software application, web management panel, associated services, and any updates thereto (collectively, the "Service").

BY INSTALLING, ACCESSING, OR USING THE SERVICE, YOU ACKNOWLEDGE THAT YOU HAVE READ, UNDERSTOOD, AND AGREE TO BE BOUND BY THESE TERMS IN THEIR ENTIRETY. IF YOU DO NOT AGREE TO THESE TERMS, DO NOT INSTALL OR USE THE SERVICE.

If you are using the Service on behalf of an organization, you represent and warrant that you have authority to bind that organization to these Terms.


1. Definitions

"Encrypted Container" means a virtual disk file (VHDX on Windows, sparsebundle on macOS) created by the Service for the purpose of encrypted data storage on your local device.

"Master Password" means the primary user-defined passphrase used to derive access to an Encrypted Container's decryption key.

"Backup Password" (also referred to as "Double Safe Password" or "Shadow Password") means an optional secondary user-defined passphrase that unlocks a separate, independent encrypted storage slot within the same disk configuration.

"Device Key" means the RSA-4096 cryptographic key pair generated on your device upon first use, used for secure transport of disk encryption keys between the Service infrastructure and your device.

"Disk Encryption Key" means the cryptographic key generated server-side and used by the operating system's native encryption subsystem (BitLocker on Windows; hdiutil AES-256 on macOS) to encrypt and decrypt the contents of an Encrypted Container.

"Web Panel" means the browser-based management interface available at app.safedisk.app.

"Subscription Plan" means the tier of Service to which you subscribe (Lite, Standard, or Business), each providing different feature access and storage allocations.

"Trusted Person" means an individual designated by the User to receive notifications about and, where applicable, intervene in certain account recovery processes.

"Organization" means a business entity account that manages multiple User accounts under administrative policies.


2. Service Description

2.1 Core Functionality

SafeDisk is data protection software that enables Users to create Encrypted Containers on their local computers. The Service provides:

2.2 Platform Requirements

The Service operates on supported versions of Microsoft Windows (with BitLocker capability) and Apple macOS (Intel and ARM64 architectures). The encryption of Encrypted Containers relies on operating system-provided encryption subsystems. SafeDisk does not implement its own block-level cipher; rather, it orchestrates the native encryption tools provided by the underlying operating system.

2.3 Network Dependency

The Service requires an active internet connection to function. Disk Encryption Keys are generated server-side, encrypted with your Device Key, and delivered to your device via our API. Authentication, Master Password validation, Disk Encryption Key retrieval, and subscription verification all require connectivity to SafeDisk servers. You will not be able to create, mount, or unlock Encrypted Containers without an active internet connection to SafeDisk servers.


3. Zero-Knowledge Architecture and Its Limitations

3.1 What We Do Not Store in Plaintext

Your Master Password and Backup Password are never stored in plaintext on our servers. Passwords are validated using Argon2id cryptographic hashing. The Disk Encryption Key is encrypted with your device's RSA-4096 public key before delivery and can only be decrypted by the private key stored on your device.

3.2 What We Do Store

To provide the Service, we store the following data on our servers:

3.3 Limitation of Zero-Knowledge

While we cannot decrypt your files, our servers are involved in password validation, key delivery, and access control. This architecture means: (a) we can enforce the 14-day Master Password Recovery process; (b) Organization administrators can lock disks and suspend members; (c) Trusted Persons can block recovery and initiate emergency locks. These features exist by design to provide account security and organizational control, and you consent to their operation by using the Service.


4. User Responsibilities

4.1 Password Management

YOU ARE SOLELY AND ENTIRELY RESPONSIBLE FOR THE CREATION, MEMORIZATION, AND SAFEKEEPING OF YOUR MASTER PASSWORD(S) AND BACKUP PASSWORD(S). SafeDisk personnel cannot retrieve, reset, or bypass your Master Password or Backup Password. If you lose your password, the only mechanism available is the Master Password Recovery process described in Section 6, which is subject to a mandatory 14-day waiting period and additional verification requirements.

You acknowledge and agree that:

(a) There is no "forgot password" shortcut for Master Passwords. The recovery process is deliberately slow and restrictive by design for security purposes.

(b) Password strength is your responsibility. While the Service enforces minimum password requirements (minimum 8 characters with a complexity score of at least 3 out of 4), these are minimum thresholds only. Choosing a weak password within these parameters increases your risk.

(c) No key escrow exists. Neither SafeDisk nor any third party maintains a backup copy of your Disk Encryption Keys in a form that can be used to bypass your Master Password.

(d) Device Key loss is catastrophic. If the Device Key stored on your computer is lost (due to operating system reinstallation, hardware failure, corruption of local application data, or any other cause), you will not be able to decrypt Disk Encryption Keys delivered for that device. You must re-register the device and initiate Master Password Recovery to regain access.

4.2 Account Security

You are responsible for:

4.3 Data Backup

SAFEDISK IS NOT A BACKUP SERVICE. The Service creates encrypted storage containers on your local device. SafeDisk does not replicate, back up, or store your files on remote servers. You are solely responsible for maintaining independent backups of any data stored within Encrypted Containers. We strongly recommend maintaining regular backups of critical data in a separate, independent system.

4.4 System Environment

You acknowledge that the proper functioning of the Service depends on factors outside SafeDisk's control, including but not limited to:


5. Registration, Authentication, and Two-Factor Authentication

5.1 Account Creation

To use the Service, you must create an account with a valid email address and a password meeting the minimum requirements (minimum 12 characters, including uppercase, lowercase, digits, and special characters). Email verification is required before account activation. We perform password breach checks (Have I Been Pwned) during registration to protect against compromised credentials.

5.2 Two-Factor Authentication (2FA)

The Service supports the following two-factor authentication methods:

Two-factor authentication is mandatory for certain operations, including Master Password Recovery and desktop application authentication. Your Organization may require 2FA for all operations.

Important: Master Password Recovery (Section 6) requires a TOTP code specifically — FIDO2 hardware keys and backup codes are not accepted for recovery. You are strongly encouraged to keep TOTP enabled even if you primarily use a hardware security key.

Upon enabling TOTP, you will receive 10 single-use backup codes. Backup codes may be used for emergency login but are not accepted for Master Password Recovery. You are responsible for storing these backup codes securely. Lost backup codes combined with loss of your 2FA device may result in permanent account lockout.

5.3 Sessions and Devices

Each login creates a session bound to your IP address and user-agent fingerprint. Access tokens expire after 15 minutes; refresh tokens expire after 7 days. You may review and revoke active sessions at any time through the Web Panel. Each device is registered with a unique RSA-4096 key pair. You may have multiple registered devices.


6. Master Password Recovery Process

6.1 Overview

If you forget your Master Password, you may initiate a recovery process. This process takes a minimum of 14 calendar days by design and is subject to the following conditions:

(a) You must authenticate with your account password and a valid TOTP code from your authenticator application. Backup codes are not accepted for recovery.

(b) Upon initiation, the Encrypted Container becomes inaccessible through the desktop application for the full 14-day period.

(c) All designated Trusted Persons are notified of the recovery request.

(d) Any Trusted Person may block the recovery at any time during the 14-day period, which cancels the process entirely.

(e) After 14 days, completion requires your account password, a valid TOTP code, and email confirmation (triple verification).

(f) Upon completion, you may set a new Master Password. The underlying Disk Encryption Key remains unchanged.

6.2 Risks and Limitations

You acknowledge and agree that:


7. Double Safe (Backup Password) Feature

7.1 Description

The Double Safe feature allows creation of a secondary encrypted storage slot associated with the same disk, accessible via a separate Backup Password. Each slot uses an independently generated Disk Encryption Key. The primary storage slot and the Double Safe slot are cryptographically independent.

7.2 User Acknowledgments

By using Double Safe, you acknowledge and agree that:

(a) Each slot has an independent password. Losing the Backup Password results in permanent loss of access to the Double Safe slot, subject only to the recovery process in Section 6.

(b) SafeDisk makes no representations regarding the legal implications of using Double Safe, including but not limited to any obligation you may have to disclose the existence of hidden storage under applicable laws or court orders. You are solely responsible for understanding and complying with the laws of your jurisdiction.

(c) Improper use of Double Safe (including but not limited to storing illegal materials, obstructing legal investigations, or violating court orders) is your sole responsibility and may expose you to legal liability under applicable law.

(d) Organization administrators may disable Double Safe for members under their Organization's security policies.


8. Subscriptions, Payments, and Service Continuity

8.1 Subscription Plans

8.5 Grace Period and Data Retention After Expiry

THIS SECTION CONTAINS CRITICAL INFORMATION ABOUT DATA DELETION.

Upon subscription expiry or non-payment:

(a) Grace Period (7 days): You retain limited access to the Service for 7 calendar days. You will receive notifications at days 0, 3, 5, and 7.

(b) Blocked Status: After the grace period expires, your account is blocked. You cannot authenticate, mount, or access Encrypted Containers through the Service. Your local Encrypted Container files remain on your device but are inaccessible without the Service.

(c) Data Deletion Warning: You will receive warnings at approximately 60 and 83 days after your account is blocked.

(d) Permanent Data Deletion (90 days after block): Ninety (90) calendar days after your account enters blocked status, all server-side data associated with your disks is permanently and irrevocably deleted, including Disk Encryption Key records, disk metadata, Trusted Person associations, and pending commands. Your user account record is preserved to allow re-subscription, but no disk data can be recovered after this deletion.

(e) Local files are not affected by server-side deletion. However, without the Disk Encryption Keys (which are deleted from our servers), the Encrypted Containers on your local device will be permanently inaccessible.

YOU ARE SOLELY RESPONSIBLE FOR EXPORTING, BACKING UP, OR MIGRATING YOUR DATA BEFORE YOUR SUBSCRIPTION EXPIRES. SafeDisk shall not be liable for any data loss or inaccessibility resulting from subscription expiry, non-payment, or the subsequent data deletion process.
