Privacy Policy

This policy outlines how Horizon handles user data.

At Horizon.Pics (Horizon), we take user-privacy extremely seriously. Whenever developing features and handling user information, we always take privacy into consideration. As privacy enthusiasts and activists, we strongly believe that privacy is needed more than ever in today's digital age. The pronouns "we" and "us" represent Horizon.Pics as a whole, including its operators and developers, while the pronoun "you" represents you, the end-user.


This privacy policy outlines how Horizon.Pics collects and handles user information. Other services have their own privacy policies which do not apply to Horizon.Pics.

Data Collection

Horizon collects user information to operate the service. The following is a list of types of data we collect, as well as the justification.

Login & Registration

  • Username

Horizon uses your username to identify you across the service.

  • Argon2id Hashed Password

Your password is used for authentication. It is never stored in plaintext, but instead in an irreversible format (hashed).

  • SHA-512 Hashed IP Address

Your IP address is logged in an irreversibly hashed format to combat against abuse while maintaining privacy.

  • Timestamp

The timestamp of login and registration is used for anonymous aggregated statistics.

  • WebAuthn Key Metadata

If opted-in, WebAuthn key metadata will be stored to securely authenticate you, such as identification strings and public keys.

User Content

  • Timestamp

The timestamps of file uploads, short link creations and paste creations are used for anonymous aggregated statistics.

  • Uploaded Files, Links, Pastes & Associated Metadata

Your uploaded files and associated metadata are persistently stored until deletion so that we can host your files and serve them. All files are stored at rest with HIPAA compliant AES-256 bit encryption.

Server-side encrypted files are encrypted twice, once by the at-rest encryption and another with a key that Horizon does not store. Horizon holds the irreversible Argon2id hashed version of the original encryption key and AES initialization vector. None of this information can be used to reverse engineer or decrypt files without the plaintext encryption password, which is not stored in plaintext on Horizon.

Links are stored so we can redirect users who access them.

Unencrypted paste content is stored so we can host it. Encrypted pastes are stored but cannot be read by anybody, including developers of Horizon, without their encryption/decryption keys. These keys are never stored by Horizon and are solely generated, stored and shown locally.

  • Settings

Your settings are stored so the service can adhere to your customization preferences.

Email Communications

Users may send emails to Horizon for reasons, including, but not limited to, billing and technical inquiries. These emails are encrypted and stored in a GDPR-compliant jurisdiction.

First-Party Metrics

To get information about the behavior of our visitors, we use Ackee. This analytics software gives us insight about our visitors only in general, but not about individuals per se, as it does not track visitors and does not store any personal identifiable information. Go to their documentation to find out what Ackee collects.

Data Sharing

We have never and will never sell, rent or sublease our users' personal information to any third party.

Explicit Consent

With your explicit consent, we may transfer your personal information.

Legal Requirement

If prompted by a legal entity with a valid warrant and/or subpoena, Horizon may share personal user information with them. If it is legal to do so, we will put out a public announcement on our website and/or social media platforms.

Data Retention

User-uploaded content is retained indefinitely until they are deleted. Users may delete their content at anytime instantly by going into their dashboards. After a file is deleted, it cannot be recovered. We do not keep logs of deleted content.

Personal user information is retained indefinitely until we receive a deletion request. Users may delete their accounts at any time in Settings.

Data Security

Horizon stores user data securely on servers that have limited access. We take precautions to prevent unauthorized access to user information. For example, sensitive information, such as passwords and IP addresses, are hashed and salted before being stored in our database. Communications between clients and servers, and between servers, are encrypted.

User-uploaded content is securely stored with HIPAA compliant at-rest AES-256 encryption.

Third Party Services
