Your data, protected
Security & Privacy
Your files are your business. We built every layer of Compress.FAST to keep it that way.
Last updated: December 2025
Encryption
All connections use TLS 1.3 with perfect forward secrecy. Files are encrypted on disk using AES-256-GCM with unique per-job keys. During compression, files are decrypted only in memory for the milliseconds-to-seconds they're being processed, then immediately re-encrypted. Decrypted data is never written to disk.
Where Your Data Lives
All processing servers are physically located in the European Union on dedicated infrastructure we control. Your files are stored and processed exclusively within EU borders, ensuring GDPR compliance and protecting your content from foreign surveillance laws.
Your files stream straight from your browser to our servers in Germany, encrypted with TLS 1.3. There's no third-party in the middle—we control the entire path from upload to deletion.
Automatic Deletion
All files are automatically deleted 1 hour after compression completes—regardless of plan tier. You can also delete files immediately after downloading. Once deleted, files are securely wiped and cannot be recovered.
What we retain (for billing and fraud prevention): job identifiers, compression type, file sizes, processing time, and credits consumed.
What we do NOT store:
- Filenames (only file extensions)
- File contents or thumbnails
- EXIF metadata extracted from images
- IP addresses (only transient rate-limiting hashes)
No Third-Party Processing
Unlike services that rely on cloud APIs, we process files entirely on infrastructure we own. We use a mix of open-source and commercial libraries with no external API dependencies. Your files are never sent to third-party services for processing.
Privacy Defaults
Image metadata stripped by default. EXIF data including GPS coordinates, camera info, and timestamps are removed from compressed images to protect your privacy.
No AI training. We do not train machine learning models on user-uploaded files. Your content is used solely for the compression you requested.
No analytics on file contents. We don't scan, fingerprint, or analyze file contents for advertising or profiling.
No filename analysis. We don't log, analyze, or monetize your filenames. We have no interest in what you're compressing or why.
