How we protect your chats and personal information (Last updated: November 11, 2026)
Welcome to Chater. Chater is a privacy-first chat app offering private chat, group chat, video calls, and more. We know your chats and personal details are deeply sensitive, so this Privacy Policy explains how we collect, use, store, share, and protect your information — and the rights you have.
Please read this policy carefully before using Chater. By registering, signing in, or continuing to use our services, you confirm that you understand and agree to this policy. If you disagree, please stop using the services.
We follow the principle of data minimization, collecting only what is needed to provide our services. This may include:
1. Account and profile information: for example, your phone number, verification codes, nickname, avatar, and bio that you provide or upload, used to create and identify your account and display your profile.
2. Contacts and communication information: for example, friends you add, groups you join, and your conversation list and identifiers. We will not read your phone contacts without your permission. If the app offers optional features such as “find friends from contacts,” we only process that data after you explicitly authorize it, and you can turn it off at any time.
3. Chat and call information: message content, media files (images, voice messages, videos, and more), and call signaling and quality diagnostics. Private chats use end-to-end encryption where technically possible, so our servers cannot read the plaintext; to deliver messages, sync across devices, and keep the service secure, we may process necessary metadata (such as conversation IDs, message timestamps, and delivery status).
4. Interaction information: We will not use such interaction information for purposes unrelated to the features.
5. Device and log information: device model, OS version, app version, network type, crash logs, and performance and security logs, used to keep the service stable, troubleshoot issues, and prevent abuse.
6. Other information you provide: for example, problem descriptions, screenshots, or contact details you submit through customer support or feedback channels, used only to handle your request.
We will not ask you for sensitive information unrelated to the chat service, and we will not sell your personal information.
We use the information above mainly to:
1. Provide, maintain, and improve Chater’s core chat features (one-on-one chat, group chat, message sync, video calls, and more);
2. Complete account registration, sign-in verification, and security checks (such as alerts for unusual sign-ins, spam prevention, and fraud prevention);
3. Send you necessary service-related notifications (such as verification codes, security alerts, and feature updates);
4. Analyze overall usage and product performance (preferring de-identified or aggregated data) to improve the experience and stability;
5. Meet legal obligations, or respond to lawful requests from law enforcement or regulators;
6. For other purposes you have separately authorized, with your consent.
We will not use the plaintext of your chats for ad targeting, nor use end-to-end encrypted private messages for algorithm training or personalized recommendations.
Chater is designed so that conversations stay, as much as possible, between the people in them.
Private chat:In conversations that support end-to-end encryption, messages are encrypted on the sender’s device and decrypted on the receiver’s device — Chater’s servers cannot read the plaintext. Keys are managed by the client; when switching devices, please follow the in-app guidance to migrate securely, so your message history remains readable.
Group chat:Group messages are visible only to group members. We process the necessary membership and delivery information to keep messages flowing and group management (such as inviting or removing members and group announcements) working. Please note that in group chats, other members may forward or screenshot what you say — share sensitive content with care.
Video calls:Call audio and video streams are used for real-time communication. We may collect technical indicators such as connection quality, latency, and packet loss to improve the call experience; these generally do not include the content of your calls.
Deleted messages:After you delete a message in the app, we stop showing it to you under our product rules and clear the corresponding data from server caches or delivery queues within a reasonable period (end-to-end encrypted content is generally not stored in plaintext on our servers). Whether a copy remains on the other person’s device depends on whether they delete it and on their local storage settings.
We do not sell your personal information to third parties. We may share necessary information only in the following cases:
1. Service providers:For example, cloud infrastructure, push notifications, SMS verification, and crash analytics providers, who process data only as necessary to deliver their services and are contractually bound not to use it for other purposes.
2. Legal requirements:Where required by law or by a mandatory order from a court or government authority, we may provide information as required; where legally possible, we will seek appropriate confidentiality protections.
3. Protecting safety:To protect the significant legitimate interests of Chater, its users, or the public (such as stopping serious fraud or conduct that endangers personal safety), we may disclose necessary information where permitted by law.
4. With your consent:Any other sharing will only happen after obtaining your explicit consent.
In the event of a merger, acquisition, or asset transfer, we will require the successor to remain bound by this policy and will inform you in a reasonable manner.
We keep your information only for the shortest period necessary to fulfill the purposes of our services, unless a longer period is required by law. After you delete your account or the retention period ends, we will delete or anonymize your information, except where the law requires us to keep it.
Your information is stored by default on servers in the regions where we operate. If providing the service requires transferring it across borders, we will assess the transfer as required by law, apply appropriate safeguards, and obtain your consent or complete the required legal procedures where necessary.
We take reasonable technical and organizational measures to protect personal information, including but not limited to: encryption in transit, access controls and least-privilege permissions, security audits, vulnerability management, and confidentiality requirements for staff.
Please understand that no internet product can promise absolute security. Keep your account, verification codes, and device lock safe; never share verification information with others; and sign out promptly after using a shared device. If you notice anything unusual with your account, contact us immediately through in-app feedback or our official channels.
To the extent permitted by applicable law, you have the following rights over your personal information:
Access and correction:View or update your nickname, avatar, and other profile details in the app.
Deletion:Delete conversations, messages, and local caches; and request deletion of specific personal information when eligible.
Withdrawing consent:Turn off optional permissions (such as notifications, photos, microphone, camera, or contact matching). Withdrawing consent may affect the related features, but does not affect the lawfulness of processing carried out before the withdrawal.
Account deletion:You can request account deletion by following the in-app guidance. After deletion, we will stop providing services to you and will delete or anonymize your personal information in line with the law and this policy, except for transaction or security records that must legally be kept or are still being processed.
Requests and complaints:You can submit requests through in-app feedback; we will verify your identity and respond within a reasonable time.
Chater is primarily intended for adults. If you are a minor, please read this policy and use the service with a parent or guardian’s supervision and consent. We do not knowingly collect children’s personal information; if we discover that we have, we will delete it promptly. Parents or guardians who wish to exercise related rights can contact us through our official channels.
Chater may include links to third-party websites, app stores, or SDKs. These third parties have their own privacy policies, and their collection and processing practices are not covered by this policy. We recommend reading their terms before use. We integrate third-party capabilities only where necessary and keep evaluating their security and compliance.
We may revise this policy from time to time. After an update, we will publish it in the app or on our website and notify you through pop-ups, announcements, or other reasonable means. If an update involves material changes (such as a substantial change to processing purposes or types), we will seek your consent again as required by law. Continuing to use the service means you are aware of the updated policy; if you disagree, please stop using the service and request account deletion.
If you have any questions, feedback, or complaints about this policy or how we handle personal information, please contact us through the “Feedback / Help” section in the Chater app. We will verify and address your concerns as soon as possible.
Thank you again for trusting Chater. We will keep treating privacy as a core part of the product — not an option.
