Privacy Policy

Effective date: May 25, 2026 (updated for opt-in clip consent, captured-participant notifications, and private saved copies)

Crowdnine (“we,” “us,” or “our”) operates the Crowdnine application and related services. This Privacy Policy explains what data we collect, how we use it, and your rights regarding that data.

1. Information We Collect

We collect the minimum data needed to operate the service:

• Account information: email address, username, and an encrypted (hashed) password.
• Usage data: rooms joined, games watched, and interaction timestamps. This data is ephemeral and automatically expires.
• Device and browser information: user agent string, collected automatically by standard web server logs.
• Clip audio and metadata: when a participant creates a clip, we capture and store a copy of recent room audio along with clip details (title, the participant who created it, the room or game it came from, duration, and timestamp). We also record which consenting participants' voices are in the clip, so we can notify them and honor removal requests; this is determined from room session information, not by analyzing the audio. If you save a copy of a clip you are featured in, we link that copy to the original so a removal can reach every copy. See Clips below.
• Extension authentication token: when you sign in to the optional Crowdnine Chrome extension, an authentication token is stored locally on your device using the browser's built-in extension storage. This token is sent only to Crowdnine servers to authenticate your sync requests, and is removed when you sign out or uninstall the extension.

2. Voice Data Handling

Crowdnine provides real-time voice chat rooms powered by LiveKit. Live audio is streamed in real time between participants and is not recorded or stored by Crowdnine during normal voice chat. This live audio is transient: it exists only for the duration of the active session and is discarded immediately after transmission. The exception is clips, described in the next section, where a copy of recent room audio is captured and stored when a participant creates one.

AI noise suppression (powered by Krisp) processes audio locally on your device. No audio data is sent to Krisp servers.

3. Clips

Participants can capture short audio clips of a voice room. Clipping is opt-in, and because a clip records and stores room audio, it is handled differently from live voice chat:

• Opt-in capture: your voice is only captured in a clip after you affirmatively allow clips of your voice. Participants who decline, who are muted, or who are not signed in are not captured. Allowing clips authorizes public sharing of your voice by link.
• What is captured: the last several seconds (up to 60 seconds) of the mixed room audio at the time the clip is created, limited to participants who allowed clips and were unmuted.
• What is stored: the clip audio file (in M4A format, stored with our object-storage provider Cloudflare R2) and clip metadata such as the title, creator, room or game, duration, timestamp, and which consenting participants are featured. We determine who is featured from room session information; we do not create voiceprints, perform speaker or biometric identification, or transcribe the audio.
• Who can access it: clips can be shared by link. A public clip is accessible to anyone who has the link, without signing in, and appears in the creator's public clip gallery. A clip set to private is accessible only to its creator.
• If you are featured: if your voice is in a public clip, we notify you and you can view it. You may save your own copy, which stays private to you and cannot be made public or shared again.
• Withdrawing consent and removal: you can withdraw your consent at any time in your account settings, which stops future capture. To remove your voice from clips that already exist, report a public clip in the app (privacy reason) or email support@crowdnine.app. An upheld privacy or erasure request deletes the original clip and every saved copy of it, including the stored audio.

4. Chrome Extension

The optional Crowdnine Chrome extension uses optical character recognition (OCR) to read the game clock from your streaming video tab. This processing happens entirely on your device. The recognized clock values are transmitted to our servers solely for the purpose of synchronizing playback between room participants. No screenshots, video frames, or streaming content are captured, stored, or transmitted.

The extension requests access to your streaming-site tab solely to detect <video> elements and to pause or seek playback on your behalf when sync commands arrive. Page content, form data, and browsing history are not read, collected, or transmitted. The extension communicates only with Crowdnine servers and uses standard browser storage to remember your authentication token between sessions.

5. Third-Party Services

We use the following third-party services:

• LiveKit: provides voice chat infrastructure. LiveKit processes audio streams in real time to facilitate communication. See LiveKit's Privacy Policy for details on their data practices.
• Cloudflare R2: stores clip audio files. Clips are stored as audio objects with our object-storage provider so they can be played back and shared.

We do not use analytics trackers, advertising networks, or any third-party services that profile our users.

6. Data Retention

• Account data (email, username, password hash) is retained until you delete your account.
• Ephemeral data (room participation, sync state, extension state) is stored temporarily in memory and automatically expires shortly after your session ends.
• Live voice data is never stored; it is streamed in real time and discarded.
• Clips are stored when created. Unpinned clips are retained on a rolling 30-day basis and then automatically deleted; pinned clips are kept until they are deleted. You can delete a clip you created at any time, which removes the stored audio file. If we remove a clip in response to a privacy or erasure request, we delete the original and every saved copy of it, including the stored audio files, regardless of the rolling retention period.

7. We Do Not Sell Your Data

We do not sell, rent, or share your personal information with third parties for marketing or advertising purposes. Your data is used solely to operate and improve Crowdnine.

8. Your Rights

You have the right to:

• Access the personal data we hold about you.
• Correct inaccurate information (e.g., update your username).
• Delete your account and all associated data. See our account deletion page for instructions.
• Data portability: request a copy of your data by contacting us.
• Withdraw consent and remove your voice: if your voice is in a clip, you can withdraw consent and request its removal even if you did not create it. Report a public clip in the app (privacy reason), or email us at support@crowdnine.app. We delete the clip and every saved copy of it, including the stored audio. Where a clip has already been shared outside Crowdnine, we take reasonable steps to notify others who hold or display it of your removal request.

To exercise any of these rights, contact us at support@crowdnine.app.

9. Children's Privacy

Crowdnine is not directed to children under the age of 13. You must be at least 13 years old to create an account. We do not knowingly collect personal information from children under 13. If we become aware that we have collected data from a child under 13, we will promptly delete the account and all associated data.

If you are a parent or guardian and believe your child under 13 has provided us with personal information, please contact us at support@crowdnine.app so we can take appropriate action.

If you have questions about this Privacy Policy or our data practices, contact us at support@crowdnine.app.

11. Changes to This Policy

We may update this Privacy Policy from time to time. If we make significant changes, we will notify you by email or through the application. Continued use of Crowdnine after changes take effect constitutes acceptance of the revised policy.
