Privacy Policy
This Privacy Policy explains how PDFirma handles information when you use the PDFirma macOS application.
Overview
PDFirma is designed to prepare, sign, and validate PDF documents on macOS using certificates available on the user's device. PDFirma is intended to work primarily on-device.
Information We Collect
PDFirma does not create user accounts and does not intentionally collect personal data for storage on our own servers.
- Documents selected by the user are processed locally on the device.
- Certificate identities are accessed through Apple system frameworks and Keychain services.
- PDFirma does not include advertising, analytics SDKs, or user tracking technologies.
How Documents and Certificates Are Used
When you use PDFirma, selected PDF documents and digital certificate identities may be accessed locally to prepare and apply digital signatures, verify signatures, and display signing or validation information.
- PDF files are opened, processed, and saved at locations chosen by the user.
- Digital certificates and private keys are accessed through macOS security services.
- Private keys are intended to remain under the control of the operating system and its secure storage.
Network Requests
Depending on the certificate and signing workflow, PDFirma may connect to third-party trust infrastructure services such as:
- Timestamp Authority (TSA) services
- Online Certificate Status Protocol (OCSP) responders
- Certificate Revocation List (CRL) distribution points
These requests are made to support digital signature validation and long-term validation workflows. The availability and behavior of these services depend on certificate issuers and external providers.
Data Sharing
PDFirma does not sell personal information and does not share user data with data brokers. However, technical signing or validation requests may be sent to third-party certificate or timestamp infrastructure when required by the signing process.
Data Retention
PDFirma does not maintain a central user database. Documents and signed outputs remain on the user's device or in locations explicitly chosen by the user. Any retention of files is controlled by the user.
Security
PDFirma is built to rely on native macOS security mechanisms, including sandboxing and Apple security frameworks, where applicable. No method of transmission or storage is completely secure, but reasonable efforts are made to reduce risk within the app's design.
Children's Privacy
PDFirma is not directed to children and does not knowingly collect personal information from children.
Your Choices
You control which documents you open, where you save output files, which certificates you use, and whether you proceed with signing operations. You may stop using the app at any time.
Changes to This Policy
This Privacy Policy may be updated from time to time. If material changes are made, the updated version will be published at this URL with a revised effective date.
