1. Information We Collect

① Social Login

② Automatically Collected

These usage statistics are collected and retained only as non-identifying aggregate totals — they are never linked to individual user IDs or IP addresses. Translation content (source or translated text) is never stored.

③ Stored Locally Only (Not Sent to Servers)

• Translation history (source text, translated text, EN relay)
• Favorites list and custom tags
• App settings (UI language, preferred language pairs, etc.)
• Login session token (kept in the device's encrypted storage; sent to the server only to verify your identity)

The items above are stored only on your device (LocalStorage / encrypted storage) and are not separately transmitted to or retained by BriSense servers.

※ Where your points are stored depends on whether you are signed in. When signed in, points belong to your account and are stored on our server (Cloudflare D1); they remain available after changing devices or reinstalling, as long as you sign in with the same account. When not signed in (guest), points are stored only on this device and are lost if the app is deleted.

④ Camera, Photos & Microphone (Optional Features)

The camera, photo library and microphone are accessed only when you actively use these features and are never collected continuously. You may revoke these permissions anytime in device settings.

2. How We Use Your Information

• Account creation, authentication, and user identification
• Point history management
• Customer support
• Personalized advertising (Google AdMob)
• Service analytics and abuse prevention

4. Third-Party Services

The table below reflects our current processors. If a processor is added or changed, we will give advance notice through this policy.

※ All processors are located in the United States. Because BriSense users are primarily in Korea, this constitutes a cross-border transfer of personal data; see the Korean section 5-1 for the statutory cross-border transfer disclosure. You may refuse the transfer by discontinuing use of the app; translation features cannot be provided without it.

5. Translation Data

Text you enter for translation is transmitted through BriSense's servers to third-party AI and machine translation services (including but not limited to those listed above) solely for the purpose of providing translations. Current providers are listed in section 4; if they change, we will give advance notice through this policy.

• Not stored — BriSense does not store translation text (source or output) on its servers. Results are stored only on your device.
• Not used for AI training — BriSense uses paid-tier APIs only for translation. Under each provider's paid-service terms, inputs and outputs are not used to train their AI models or improve their products. On the backup route (OpenRouter) we additionally opt out of training use and exclude providers that may use data for training.
• Short-term retention by providers — AI providers may retain inputs/outputs for a limited period (up to 55 days) to detect abuse and policy violations. This is not for training, and data is deleted afterwards.
• Country restricted — Providers that process translation data are restricted to US-based companies.
• Each third-party provider's own data handling policy also applies.

5-1. Entering Sensitive Information

BriSense is used in everyday situations — hospitals, government offices, family conversations — and health details or personal circumstances may naturally appear in what you translate. We treat this as normal use, and protect it as follows.

What we do to protect it

• Nothing kept on our servers — translation text (source and output) is not stored on BriSense servers. Results stay on your device.
• Encrypted in transit — all transmission uses HTTPS.
• Country restricted — providers processing translation data are restricted to US-based companies.
• Not used for AI training — we use paid-tier APIs only; under those terms inputs and outputs are not used to train models or improve products. The backup route additionally opts out.
• We don't read your translations — statistics are collected only as non-identifiable aggregate counts.

What you should know

• To translate, your input must be sent to third-party AI / machine translation services. This is inherent to how translation works.
• Each provider's own data handling policy applies to what is sent.
• We therefore recommend not entering national ID numbers, bank/card numbers, or passwords into the translation box. Such data does not need translating, and omitting it does not limit your use of the service.
• When translating another person's personal information, please make sure you have their consent.

6. Your Rights

You may request access to, correction of, deletion of, or restriction on processing of your personal data at any time via Account → Withdraw in the app or by emailing brisense@daum.net. We will respond within 10 business days.

7. Children's Privacy

BriSense is not directed at children under 14. We do not knowingly collect personal information from children under 14. If we become aware that we have collected such information, we will delete it promptly.

8. Opt-Out of Personalized Ads

• Android: Settings → Google → Ads → Delete Advertising ID or Opt out of Ads Personalization
• iOS: BriSense does not request App Tracking Transparency permission and does not collect the advertising identifier (IDFA). Only non-tracking ads are served on iOS.
