1. Information We Collect

(4) Security & authentication

- Authentication tokens (session/refresh tokens) — stored temporarily on our servers
2. How We Use Information
- Identifying members, sign-in, and account management
- Providing core messenger features such as messages, files, schedules, and polls
- Real-time sync across devices and sending push notifications
- Providing unified search (messages, file names, channels, users)
- Generating an AI summary of unread conversations, only when you request one (see Sections 5 and 6)
- Preventing abuse and strengthening account security through device binding
- Responding to inquiries and delivering notices
- Improving service quality and analyzing errors
3. Retention Period
In principle, we delete your information without delay upon account withdrawal. Where retention is required by law, we keep it for the applicable period.
- Records on contracts or withdrawal of subscription: 5 years (Act on Consumer Protection in Electronic Commerce)
- Records on payment and supply of goods: 5 years (same Act)
- Records on consumer complaints or dispute handling: 3 years (same Act)
- Access logs (sign-in records): 3 months (Protection of Communications Secrets Act)
Messages and files you create are handled according to the relevant workspace/channel policy and your deletion requests.
4. Provision to Third Parties
We do not provide your personal information to third parties beyond the purposes stated in this Policy, except:
- when you have given prior consent; or
- when required by law or lawfully requested by an investigative authority.
5. Processing Entrustment
To operate the Service smoothly, we entrust processing tasks as follows.
| Processor | Task | Data |
|---|---|---|
| Google LLC (Google Cloud Platform) | Operating server, database, and file storage infrastructure | All personal data processed to provide the Service (account, messages, files, etc.) |
| Google LLC (Firebase Cloud Messaging) | Sending push notifications | Device push token; notification content (message preview, sender display name, channel name, attachment file name) |
| Apple Inc. (APNs) | Delivering iOS push notifications | Device push token; notification content (message preview, sender display name, channel name, attachment file name) |
| Anthropic PBC | Generating an AI summary of unread conversations, only for conversations you explicitly ask to summarize | Text of the unread messages in that conversation, the sender display names shown with them, and the workspace and conversation identifiers |
6. Cross-Border Transfer
We transfer personal data abroad (by entrustment or provision) for service infrastructure, push notifications, and social sign-in as set out below. All recipients are located in the United States, and data is transmitted over the network at the time each feature is used.
| Recipient (contact) | Purpose | Data transferred | Retention |
|---|---|---|---|
| Google LLC (policies.google.com/privacy) | Server and file storage infrastructure (Google Cloud Platform), push notifications (Firebase Cloud Messaging), sign-in with a Google account | Infrastructure: all personal data processed to provide the Service · Push: Device push token; notification content (message preview, sender display name, channel name, attachment file name) · Sign-in: account identifier, email address, and name exchanged during authentication | Until the purpose is fulfilled or you delete your account |
| Apple Inc. (www.apple.com/legal/privacy) | iOS push notifications (APNs), Sign in with Apple | Push: Device push token; notification content (message preview, sender display name, channel name, attachment file name) · Sign-in: account identifier, email address, and name exchanged during authentication | Until the purpose is fulfilled or you delete your account |
| Microsoft Corporation (privacy.microsoft.com) | Sign-in with a Microsoft account | Account identifier, email address, and name exchanged during authentication | Until the purpose is fulfilled or you delete your account |
| Anthropic PBC (www.anthropic.com/legal/privacy) | Generating an AI summary of unread conversations, at your request | Text of the unread messages in that conversation, the sender display names shown with them, and the workspace and conversation identifiers | Not retained after the summary is returned, and not used to train models under Anthropic's commercial terms. Exception: where retention is required by law, or where content is flagged by Anthropic's automated trust and safety systems, it may be retained for up to 2 years |
You may object to these transfers by contacting us (Section 11). However, if you object to the transfer to our service infrastructure (Google Cloud Platform), you will not be able to use the Service, and objecting to the transfers for push notifications or social sign-in will make those features unavailable.
The AI summary transfer is different: nothing is sent unless you press the summary button. Conversations are never sent to Anthropic in the background, and simply not using the feature means no transfer takes place. A workspace administrator may also turn the feature off for the whole workspace.
7. Your Rights
- Request access, correction, deletion, or suspension of processing of your data
- Withdraw membership (revoke consent) — via in-app settings or the contact below
- You may exercise these rights in writing or by email, and we will act without delay.
8. Destruction of Data
- We destroy data without delay once the retention period ends or the purpose is fulfilled.
- Electronic files: permanently deleted in an unrecoverable manner
- Paper documents: shredded or incinerated
9. Security Measures
- Encryption of sensitive data such as passwords, and encryption in transit (HTTPS/WSS)
- Account protection via two-factor authentication (OTP) and device binding
- Minimized access privileges, access control, and retention of access logs
- Vulnerability checks and security updates
10. Children's Privacy
The Service is intended for users aged 14 and older and does not knowingly collect personal information from children under 14.
