Privacy & Legal Questions
How does PeerCache protect user privacy?
PeerCache improves privacy by truncating file hashes in its log files. This reduces the amount of identifiable information stored while still allowing basic cache statistics and diagnostics.
Is file metadata stored in the cache?
PeerCache improves privacy by truncating file hashes in its log files. This reduces the amount of identifiable information stored while still allowing basic cache statistics and diagnostics.
Is file metadata stored in the cache?
No. PeerCache does not store file metadata such as filenames, descriptions, or content details. Files are identified only by their file hash values.
Can logging be completely disabled for additional privacy?
Yes. Logging can be disabled by setting the following option in the PeerCache.ini configuration file:
AccessLog=/dev/nullDisabling logging may prevent certain reporting and statistics features from functioning correctly, including:
- Calamaris daily text reports
- Unique IP statistics
- Bandwidth savings calculations
Does running a cache turn the ISP into a P2P content provider?
No. Cached content is never included in Peer-to-Peer search results. Files stored in the cache can only be accessed when the same content is already available through the P2P network.
What information is logged by PeerCache?
PeerCache logging is similar to a standard Squid cache log. Each request recorded in the access.log file may include:
- Date and time
- Request duration in milliseconds
- Request status (hit or miss)
- Number of transferred bytes
- Requested URL
datetime | request duration | request status | bytes transferred | GET http://10.0.0.1/
Are full user IP addresses logged?
No. Starting with PeerCache version 1.2, full client IP addresses are no longer stored in logs.
Statistics are provided only in aggregated form, allowing administrators to measure information such as the number of unique users accessing the cache during a given period without identifying individual users.
How long are log files retained?
PeerCache log files are typically retained for 10 days.
