WalkthroughAdded ChangesPrivacy Policy
Estimated code review effort: 1 (Trivial) | ~3 minutes Merge Risk: 🟡 Moderate · up to This documentation-only change adds a privacy policy but currently leaves key statements incomplete or potentially misleading: it does not clearly define loopback token scope, identify Google’s STUN service and exchanged metadata, or specify retention and deletion for shared data, tokens, and logs. These gaps could make the published policy inaccurate, so the PR is not merge-ready until they are addressed. Suggested labels: Poem

clarify that requireAuth permits loopback requests without token validation and
that the token protects non-loopback connections, avoiding any implication of
universal token enforcement.
- Around line 61-69: Update the WebRTC third-party disclosure in PRIVACY.md to
explicitly identify Google’s STUN service at stun:stun.l.google.com:19302 as a
recipient, stating that it may receive ICE connectivity metadata such as network
addresses and ports during connection setup while the Rein server handles
signaling and peers exchange media and data directly.
- Around line 79-83: Update the Data Deletion section to document server-side
retention: shared files and metadata remain in memory until explicitly deleted
or process termination, and file deletion removes both; authentication tokens
persist in tokens.json and expire after 10 days of inactivity; logs persist in
~/.rein/log.txt with no defined retention or deletion behavior. Also specify
whether deletion affects configuration and logs.

Identify Google’s STUN service as a WebRTC recipient.
The client and server configure stun:stun.l.google.com:19302. Google can receive ICE connectivity metadata, including network addresses and ports, during connection setup. The Rein server handles signaling, and connected peers exchange media and data directly. Update the policy to identify Google’s STUN service and the metadata it receives.

Clarify the scope of token authentication.
requireAuth authorizes loopback requests before checking a token. State that the token protects non-loopback connections, or revise the wording so it does not imply universal token enforcement.

| ## Data Deletion | ||
|
|
||
| Where information is stored locally, you can generally remove it by using the App's available data-clearing features, clearing the data through your device settings, deleting shared files through the App, or uninstalling the App. | ||
|
|
||
| Because Rein is designed as a local application rather than a centralized cloud service, Rein does not maintain a central user account or centralized store of user information. |

Document concrete retention and deletion behavior for server-side data.
The server keeps shared files and metadata in memory until deletion or process termination. File deletion removes both from the in-memory store. Authentication tokens persist in tokens.json and expire after 10 days of inactivity. Logs persist in ~/.rein/log.txt, with no retention or deletion behavior defined. Document these outcomes and specify how deletion affects configuration and logs.
