Privacy Policy

AI Talk Assistant ("the Service") values your privacy. This policy is effective as of October 13, 2026.

1. Information We Process and Why

The Service operates anonymously without sign-up and does not collect account information that identifies you, such as your name, email, or phone number. We process the following:

Category	Items	Purpose	Retention
Notification (conversation) content	Chat room name, sender display name, message content, timestamps	Provide AI summary and deleted-message viewing	Stored only on your device (deleted when the app is uninstalled). See section 2 for how summary requests are handled
Device / technical info	Device identifier, app version, OS version, device model	Notices, version checks, responding to inquiries, push notifications, usage limits	During service operation
Push notifications	FCM push token	Sending notices and event notifications	Until notifications are disabled or the app is uninstalled
Advertising identifiers	Advertising ID (ADID / IDFA), device information, coarse IP-based location	Ad delivery, measurement, and fraud prevention (collected directly by ad providers)	Per each ad provider's policy
App usage analytics	Screen views, feature usage events, pseudonymous identifiers	Service improvement and usage analytics (Firebase Analytics)	Per Google's policy
Subscription payment info	Google Play / App Store purchase token, subscription status and expiry	Verifying paid subscription entitlement	As required by applicable law after the subscription ends
Inquiry content	Title, body and attached photos you submit in support inquiries	Responding to your inquiry (AI is used to review it and draft a reply, see Section 2)	Deleted 1 year after the inquiry is resolved
AI help questions	Questions you type in "Ask AI Talk Assistant"	AI answers about how to use the app, plans and settings	Questions and answers are stored only on your device. Our server keeps only questions with phone numbers, emails and resident registration numbers masked, up to the latest 1,000, to check answer quality (not linked to any device identifier); older ones are deleted first. See section 2

The device identifier points to a device only; it is not linked to your real name, contact details, or identity. You can reset your advertising ID or opt out of personalized ads at any time in your device settings (see section 6).

2. AI Summarization, AI Help Answers, Support Inquiry Review and Third-Party (International) Processing

• Phone numbers, emails, account numbers, national ID numbers and addresses contained in message bodies are automatically masked on your device, before they leave the device ([PHONE], [EMAIL], [ACCOUNT], [SSN], [ADDRESS]). The originals of these items are never sent to our servers or to the AI providers (Anthropic and Google).
• What is not masked: To preserve context for the summary, the chat room name and sender display names are transmitted without masking. These are the names shown in your messenger and may contain real names. If you do not use the summary feature, no conversation data leaves your device.
• Only the text processed as described above is sent, via our server (Naver Cloud), to Anthropic PBC's Claude API or Google LLC's Gemini API to generate the summary. If one does not respond, the other processes the request.
• Our servers do not store or log the message bodies or the generated summaries. For error handling and usage management, minimal operational records (chat room identifier, message count, timestamp — never the chat room name, sender names, or message bodies) are written to server logs and are deleted within 3 months.
• Anthropic does not use Claude API request content to train its models and automatically deletes it within 30 days of receipt. Only content flagged for a usage policy review may be kept for up to 2 years.
• Under the Gemini API terms, Google does not use this request content to train its models. It logs requests for a limited period only to detect and prevent usage policy violations and to meet legal obligations, then deletes them.
• International transfer: In this process, the text may be processed on Anthropic's or Google's servers located outside your country (Processor: Anthropic PBC (privacy@anthropic.com, 548 Market St, PMB 90375, San Francisco, CA 94104); Country: United States; Data: masked message text, chat room name, sender display names; Timing/method: transmitted over the network when you request a summary; Purpose: AI summary generation; Retention: deleted within 30 days of receipt (up to 2 years if flagged for a usage policy review), not used for training) (Processor: Google LLC; Country: United States and others; Data: masked message text, chat room name, sender display names; Timing/method: transmitted over the network when you request a summary; Purpose: AI summary generation; Retention: not used for training, deleted after the usage policy monitoring period).
• AI help answers ("Ask AI Talk Assistant"): Only the question you type is sent through our server (Naver Cloud) to Google LLC's Gemini API or Anthropic PBC's Claude API to create an answer. Chats collected on your device are not sent. Phone numbers, emails and resident registration numbers in the question are masked on our server before sending. The recipients, destination country and retention are the same as above; the transferred item is the masked question, transferred over the network when you ask, for the purpose of AI help answers.
• Support inquiry review: To review and answer support inquiries quickly, we send the inquiry through our server (Naver Cloud) only to Anthropic PBC's Claude API, which reads and classifies it and drafts a reply. An operator checks every AI-drafted reply before it is sent. The data sent is the inquiry title, the messages exchanged between you and our operator (up to 1,500 characters per message), whether a photo was attached, the time it was written, and parts of operator replies sent to other inquiries in the same app (up to 3); when an operator writes a follow-up, the conversation of that inquiry and the operator's notes. Photos and device identifiers are not sent. Anything you write in the message yourself (such as contact details) is sent as written. The recipient (Anthropic PBC), destination country and retention are the same as above; the transferred item is the inquiry content, transferred over the network usually within minutes after the inquiry arrives (within 3 days if processing is delayed) and when an operator asks for another review, for the purpose of reviewing the inquiry and drafting a reply.
• You may refuse this international transfer, in which case the AI summary feature and AI help answers are unavailable (you can still contact us through support inquiries). All other features continue to work normally.
• If you do not want your support inquiries transferred abroad, email our privacy officer at contact@dksw4.com with the inquiry number, or the inquiry title and the date you sent it. Inquiries you send after that are not transferred abroad; an operator reviews and answers them directly, and the Service remains fully available to you.

3. Data Storage and Protection

• Local-only storage: Collected conversation content is stored only in the app's internal storage. It is transmitted as described in section 2 solely when you request an AI summary; otherwise conversation data never leaves your device.
• No server retention: We do not store original conversation text on our servers; it passes through transiently for summarization only.
• Access control: Access to systems processing personal information is minimized and access records are retained.
• App lock and biometrics: If you turn on app lock, the passcode and the answer to your recovery question are stored only in encrypted storage on your device as irreversible hashes and are never sent to our servers. Biometric data (fingerprint, face) is verified by the device operating system on the device itself; the app does not collect, store, or transmit biometric data and only receives whether authentication succeeded.
• Encrypted communication: All communication is encrypted and transmitted over HTTPS (SSL/TLS).

4. Sale or Sharing of Personal Information

We do not sell your personal information for money. However, the Service shows advertising, and advertising identifiers may be made available to our ad providers to deliver and measure personalized ads. Under the CCPA/CPRA this may be treated as "sharing" for cross-context behavioral advertising. You can opt out at any time using the device controls described in section 6; opting out does not limit any feature of the Service. Conversation content is never used for advertising.

5. Permissions

• Notification access: Needed to read messenger notifications and collect conversation content (for summaries and deleted-message viewing).
• Exclusion from battery optimization: Needed to continuously receive notifications in the background.
• Notification display: Needed to show notices and event push notifications.
• Photos / storage access: Used only when you attach a photo to a support inquiry; we never access photos you did not select.
• Biometric permission: Used only if you choose to unlock app lock with your fingerprint or face. Biometric data itself is never passed to the app.

You can revoke any permission at any time in your device settings; doing so limits only the related feature.

6. Advertising and Analytics

The Service shows advertising to fund its free features and analyzes usage data to improve the product.

• Ad providers: Google LLC (AdMob) and Kakao Corp. (Kakao AdFit). Each provider may directly collect advertising identifiers (ADID/IDFA), device information, and coarse IP-based location for ad delivery, measurement, and fraud prevention.
• Analytics: We use Google LLC's Firebase Analytics to collect screen views and feature usage events for statistical analysis. Conversation content is never included in analytics.
• Opting out of personalized ads
  • Android: Settings > Google > Ads — reset your advertising ID or opt out of ad personalization.
  • iOS: Settings > Privacy & Security > Tracking — deny the app's tracking request.
• Opting out does not limit any feature. A paid subscription is available if you prefer an ad-free experience.
• International transfer: Advertising identifiers and usage events may be processed on servers operated by Google LLC (United States and others) and Kakao Corp.; retention follows each provider's policy.

7. Children

The Service is not intended for children under 13 (or under 14 where required by local law, such as the Republic of Korea), and we do not knowingly collect personal information from such children. If we learn that a child below the applicable age has used the Service, access will be restricted and the related information deleted without undue delay.

8. Your Rights

• You can revoke permissions at any time in your device or app settings.
• Uninstalling the app deletes all data stored on your device.
• For questions, access, or deletion requests regarding your information, contact us via in-app support or the contact below.
