Privacy notice

Your document stays in your browser.

CREDA-Stamp is designed to verify document integrity without uploading, transmitting, or storing your files.

Last updated: June 2026

Primary rule: Files selected in CREDA-Stamp are processed locally in your browser. They are not uploaded, transmitted, or stored.

1. Local processing

CREDA-Stamp computes file hashes directly in your browser using built-in cryptographic functions. The file remains on your device during both record creation and verification.

  • No file uploads;
  • No file transmission;
  • No server-side processing of your documents;
  • No storage of your files by CREDA-Stamp.

2. Integrity records

CREDA-Stamp generates a JSON integrity record that you may download and store. This record is not retained by CREDA-Stamp.

You are responsible for saving, managing, and protecting any records you create.

3. Information included in a record

  • SHA-256 file hash;
  • Timestamp of record creation;
  • File name and basic metadata (when available);
  • Optional information you choose to include.
Do not include confidential or privileged information in optional fields unless you are comfortable storing that information in the generated record.

4. Contact form

If you contact us, we may receive the information you choose to provide (such as name, email, and message). This information is used only to respond to your inquiry.

5. Analytics and technical data

Standard website hosting or analytics tools may collect general technical information (such as browser type, device, or IP address). These tools do not receive the contents of files processed by CREDA-Stamp.

6. Security considerations

CREDA-Stamp relies on your device and browser for security. You are responsible for maintaining the security of your systems and stored records.

7. No certification of content

CREDA-Stamp verifies whether a file matches a previously recorded version. It does not certify authenticity, authorship, execution, or legal validity.

8. Legal disclaimer

No legal advice: Information provided on this site is for general informational purposes only and does not constitute legal advice. Use of CREDA-Stamp does not create an attorney-client relationship.
