Privacy Policy

Overview

PlayParty.io ("PlayParty.io", "we", "us", "our") operates a real-time synchronized media watch-party platform, companion browser extension, and supporting server infrastructure. We are committed to transparency in how we collect, process, and safeguard your personal data.

While PlayParty provides synchronization, communication tools, and media compatibility utilities, video and audio playback is rendered directly in each participant's web browser. We do not permanently host, transcode, or store proprietary video libraries on our servers. This policy explains what information we process, the purposes of processing, and your statutory privacy rights.

Information We Collect & Process

1. Account & Profile Information

When you create an account or authenticate via third-party sign-in (such as Google OAuth or Google One Tap), we store your account profile securely in our database:

• Identity & Profile Details: Email address, chosen username, display name, and unique account identifier.
• Authentication Data: Securely hashed authentication tokens or federated authentication identifiers.
• Profile Avatars: Selected default preset identifiers or custom avatar images uploaded through our secure media storage provider (Cloudinary).
• Account Lifecycle State: Verification status, account preferences, and scheduled deletion grace period timestamps.

2. Room Synchronization & Watch History

To maintain real-time playback synchronization and provide room management features:

• Room Metadata & Presence: Room identifiers, titles, access settings, host permissions, and real-time participant presence.
• Playback Coordination State: Active media URLs, provider type (e.g. standard video, streaming playlists, third-party embeds), current playback timestamp, and playback status (playing/paused).
• Watch History: For authenticated users, recently visited room details and media titles are stored in your account history (capped at 20 entries and automatically purged after 90 days). Guest users have watch history stored solely on their local device.
• Room Moderation Records: Temporary cooldown records and ban status entries to protect rooms against unauthorized re-entry and spam.

3. Direct Client-to-Source Streaming & Zero Media Hosting

PlayParty.io is architected for privacy and zero server-side media processing:

• Direct Client Decoding: All video and audio streams decode natively within each participant's local web browser directly from the original source (e.g. YouTube, Twitch, Vimeo, or user-provided links).
• Zero Media Relaying & Zero Storage: Our servers do not proxy, download, transcode, relay, or store third-party video or audio files. Only lightweight playback synchronization timestamp signals (<1 KB JSON packets) pass through our synchronization infrastructure.
• Domain Protection: Our application validates media URLs to protect users against malicious endpoints and prevent server-side network abuse.

4. Search & Media Discovery

Our platform includes search and content exploration features:

• When you perform a search or browse media suggestions, queries and public media identifiers are processed to retrieve titles, thumbnails, and stream metadata.
• Search queries are processed transiently to fulfill the immediate request and are not linked to your user profile or used to construct behavioral advertising profiles.

5. Real-Time Communications & Messaging Architecture

PlayParty.io provides two distinct messaging and communications systems, engineered with data minimization and encryption at their core:

• Watch Room Communications (Strictly Ephemeral in RAM): Watch Room interactions—including group text chat, emoji reactions, and WebRTC voice and video streams—are transmitted in real time between participants using LiveKit SFU data channels and real-time WebSocket broadcast channels. Audio/video streams and room chat messages exist solely in volatile memory (RAM) in transit and within participants' active browser tabs. Watch Room chat messages are never written to databases, disk, or server logs. When a Watch Room session terminates or all participants depart, all room chat data is permanently discarded.
• Direct Friends Messages (End-to-End Encrypted & Stored as Ciphertext): One-on-one private messaging between friends is protected by client-side End-to-End Encryption (E2EE) utilizing WebCrypto ECDH (Elliptic Curve Diffie-Hellman P-256) for shared key agreement and AES-GCM-256 for message payload encryption. Messages are encrypted locally on the sender's device before transmission. PlayParty servers receive and store only the encrypted ciphertext, cryptographic initialization vectors (IVs), sender and recipient account identifiers, and delivery timestamps in our database to facilitate asynchronous cross-device delivery. Plaintext message contents are never stored on, inspected by, or decipherable by PlayParty servers.
• Cryptographic Key Material: Users' public cryptographic keys and encrypted key-backup containers are maintained in our database to enable contact discovery and multi-device key agreement. Private encryption keys remain stored locally within browser IndexedDB or native secure storage on the user's local device.

6. Law Enforcement & Legal Disclosure Boundaries

We believe in complete transparency regarding what data our technical architecture can and cannot produce in response to lawful legal processes (such as subpoenas, court orders, or search warrants):

• Watch Room Transcripts & Media: PlayParty is technically incapable of producing Watch Room chat transcripts, message logs, or voice/video recordings under any subpoena or court order because the data does not exist on our servers.
• Direct Message Content: Because Direct Messages are end-to-end encrypted client-side, PlayParty cannot produce plaintext message transcripts or intercept conversations. In response to valid, legally binding process with proper jurisdiction, PlayParty can only produce raw encrypted ciphertext and associated transmission metadata (sender ID, recipient ID, message timestamp, message ID).
• Metadata Footprint: The metadata we maintain is strictly limited to: user account profile records (email address, username, display name, account creation timestamp), mutual friendship associations, active room ownership records, and server watch history (capped at 20 entries, automatically purged after 90 days). Transient IP address hashes used for anti-abuse rate limiting reside in volatile memory and are not stored in database records.

7. Local Device & Browser Storage

We store certain essential and functional data locally in your browser (via local storage and session storage):

• Display names, guest identifiers, and cached profile details.
• Audio volume preferences, interface layout settings, and room host credentials.
• Cookie preferences and Google Consent Mode settings.
• Secure authentication session tokens (cleared upon sign-out).

8. Companion Browser Extension

If you install the optional PlayParty companion extension, it operates strictly on demand:

• Detects public video stream URLs on the active browser tab when you choose to start or join a party.
• Temporarily retains detected stream references in local browser session storage (automatically cleared when your browser closes).
• Adjusts network request headers (specifically setting media-origin Referer and Origin, and removing fetch-metadata headers) via Chrome's local declarativeNetRequest session rules solely to allow the player to fetch and decode user-selected HLS/DASH media streams across domains, without modifying DRM or circumventing subscription access controls.
• Does not collect, track, or transmit your broader browsing history or navigation data to PlayParty servers.

9. Privacy-Preserving Security & Rate Limiting

To protect our infrastructure against distributed denial-of-service (DDoS) attacks, brute-force attempts, and automated abuse:

• We use privacy-preserving, cryptographically hashed representations of IP addresses in volatile memory to calculate request rates. These volatile memory rate-limiting counters are automatically cleared within 15 minutes.
• Raw IP addresses are not stored in our application database records. Standard connection logs may be processed transiently by our content delivery and network security providers for infrastructure defense.

10. Transactional Notifications

We use reputable transactional email delivery providers (such as Resend and Brevo) to send critical account notifications, email verification links, and password reset instructions. We do not send unsolicited marketing emails or sell your contact information.

11. Performance Telemetry & Error Monitoring

• Google Analytics 4 (GA4): Measures aggregated traffic patterns and device metrics. GA4 operates under Google Consent Mode v2 and is only loaded when consent is granted.
• Application Error Diagnostics: We use error-tracking tools (such as Sentry) to monitor unhandled application errors and system crashes to improve software stability.
• Bug Submissions: When you voluntarily submit feedback or bug reports, the details you provide (description, technical context) are reviewed to diagnose and resolve software bugs.

How We Use Information

• Facilitate real-time playback synchronization and ephemeral room chat between participants.
• Provide low-latency voice and video communication channels.
• Deliver end-to-end encrypted direct messages between mutual friends.
• Authenticate user accounts, enforce account security, and manage user profiles.
• Prevent platform abuse, mitigate DDoS threats, and maintain server reliability.
• Troubleshoot application crashes and improve service performance.

We never sell, rent, or monetize your personal data. We do not use your personal information for targeted advertising.
