This Privacy Policy describes how Is that blake3 hash taken ("we", "us", or "our") handles information in connection with the operation of the Is that blake3 hash taken website ([is-that-blake3-hash-taken.top]) (the "Service").

Information We Collect

We aim to minimize unnecessary data collection. The information we handle includes:

• Claimed Hashes: When you use the Service to "claim" a BLAKE3 hash, we store the hash itself, the date and time of the claim, and any optional nickname or message you provide. This information is stored in our database to make the claim public and verifiable via the Service.
• Text Submitted for Hashing: When you submit text to be hashed via our API (`/api/hash-text`), we process the text solely to generate the corresponding BLAKE3 hash. We do not store the submitted text or the resulting hash after the request is completed.
• Files Submitted for Hashing: When you upload a file to be hashed via our API (`/api/hash-file`), the file is temporarily stored on our server solely for the purpose of generating its BLAKE3 hash. The file is deleted from our server immediately after the hash is calculated and returned to you. We do not store the file content or the resulting hash (unless you subsequently choose to claim that hash).
• Log Data: Like most websites, our servers automatically record information ("Log Data") created by your use of the Service. Log Data may include information such as your IP address, browser type, operating system, the referring web page, pages visited, location, your mobile carrier, device information, and search terms. We use Log Data to operate, maintain, secure, and improve our Service. Log data is typically retained for a limited period (e.g., 30 days) before being deleted, unless required for security investigations or legal obligations.

How We Use Information

• To Provide the Service: We use claimed hash data (hash, date, nickname, message) to display claims on the website and allow users to check if a hash has been claimed. We process submitted text and files only to perform the hashing function you request.
• To Maintain and Improve the Service: We use Log Data to monitor the usage of the Service, diagnose technical problems, ensure security, and improve the user experience.

Data Storage and Retention

Claimed hashes, along with their associated date, optional nickname, and optional message, are stored persistently in our database to fulfill the core function of the Service.

Text submitted for hashing is not stored.

Files submitted for hashing are stored only temporarily during the hashing process and are deleted immediately afterward.

Log Data is retained only as long as necessary for operational, security, and analytical purposes, typically for a short period, after which it is deleted or anonymized.

Data Security

We implement reasonable technical and organizational measures to protect the information we handle. However, no internet transmission or electronic storage method is 100% secure. While we strive to protect your information, we cannot guarantee its absolute security.

Third-Party Services

We may use third-party services (e.g., hosting providers) to operate our website. These third parties may have access to Log Data as part of providing their services, but they are typically obligated not to disclose or use it for other purposes.

Cookies

We currently do not use cookies for tracking or advertising. We may use essential cookies if necessary for website functionality (e.g., session management if user accounts were implemented), but we aim to avoid non-essential cookies.

Your Rights

Regarding the data associated with claimed hashes (the hash, date, nickname, message): Depending on your jurisdiction, you may have rights to access, correct, or request deletion of this data. Please contact us using the details below if you wish to inquire about these rights.

For ephemerally processed data (text/files for hashing) and Log Data, there is typically no persistent personal data directly associated with you that you would need to access, correct, or delete after the processing or retention period.

Changes to This Policy

We may update this Privacy Policy from time to time. We will notify you of any changes by posting the new Privacy Policy on this page and updating the "Last Updated" date. You are advised to review this Privacy Policy periodically for any changes.
