Privacy Notice

1. File Handling & Processing

Blackpdf is designed to prioritize privacy. Most file conversions happen directly within your browser, meaning your files are never uploaded to our servers. This ensures that your data stays private and secure on your device.

In cases where a conversion requires more resources than your browser can handle, files may be transferred to our servers for processing. When this happens:

• End-to-End Encryption: Your files are encrypted during transfer with 256-bit TLS encryption.
• Automatic Deletion: Files are automatically deleted after processing, leaving no trace.

By default, Blackpdf does not store any files in your browser or on our servers once processing is complete.

However, if you choose to reuse a processed file in another tool (for example, merging a PDF and then compressing it), you may opt to temporarily store that file in your browser’s local storage.

This feature is entirely optional and happens only with your action or consent to improve your experience.

The file remains on your device and is never uploaded to our servers unless required for the next processing step, such as compression or other resource-intensive tasks. In those cases, the locally stored file is securely encrypted and transferred only for that operation, then automatically deleted after processing.

For more details about our technical security measures, please see our Security Page.

2. Third-Party Service Providers

To enable smooth in-browser file conversions and performance improvements, Blackpdf may use trusted third-party service providers, including:

• CDNs (e.g., cdnjs) to deliver scripts and libraries for browser-based conversions
• External APIs to facilitate certain features

These providers do not have access to your files or content. They only provide the tools needed for your browser to process files locally or to enable server-side functionality when necessary.

3. Google Ads & Advertising

Blackpdf may display ads to users on the free tier to support ongoing operations and infrastructure. To provide relevant ads:

• We use Google Ads and other advertising partners.
• These services may use cookies, web beacons, and other technologies to serve personalized or non-personalized ads.
• Advertisers may collect anonymous information such as device type, browser, or approximate location, but they do not have access to your files.

We comply with Google Ads policies and legal requirements, including disclosures for cookies and personalized advertising.

4. Analytics & Usage Data

We do not track personal information from your files. However, we collect anonymous usage data and error reports to improve our products. This includes information such as:

• Errors encountered during conversion
• Feedback provided through the site
• Anonymous usage patterns

We use tools like Google Analytics for this purpose. This data does not include any content from your files.

Data Retention: Anonymous analytics and error logs are retained for up to 12 months to improve service performance.

5. Cookies

Blackpdf uses cookies to enhance your experience and comply with necessary functionality:

• Required Cookies: Necessary for features like analytics, preserving your preferences, and ensuring the service works correctly.
• Analytics Cookies: Used to understand anonymous usage patterns and improve performance.
• Advertising Cookies: Used by Google Ads and partners to deliver ads and measure ad performance.

For a detailed explanation of cookies and how you can manage them, see our Cookie Policy.

6. GDPR & Data Protection

We are committed to GDPR compliance and the protection of personal data:

• No personal files are stored beyond processing.
• Any optional data collected (like anonymous analytics or ad identifiers) is handled in aggregate and never linked to individuals.
• Users retain rights to access, modify, or delete personal data where applicable.

Cross-Border Transfers: Any server processing may involve data transfer to secure servers in India. Industry-standard encryption and compliance with applicable data protection laws are applied.

Legal Basis for Processing:

• Performance of a service requested by the user (file conversion)
• Legitimate interest for analytics and advertising

7. Security Measures

We implement technical and organizational measures to protect your files and data. For full details, see our Security Page.

8. Third-Party Services

Some features may rely on third-party services (e.g., analytics providers, CDNs, advertising networks). We ensure these providers follow strict privacy standards and do not access your files.
