1. Service Description

BriSense is an AI-powered translation app that uses English as a relay language to improve translation quality between non-English language pairs. The translation process follows three steps:

1. Step 1: Source language → English
2. Step 2: English → Target language
3. Step 3: English → Source language (back-translation for verification)

2. Free Translation & Daily Limits

① Free AI translation is provided within a per-user daily limit. Base limits differ for guest (not logged in) and logged-in users; the specific numbers follow in-app notices and may change depending on service conditions. Limits reset at midnight KST.

② For guests, additional daily caps based on device and network (IP) may apply to prevent circumvention via app reinstallation or multiple devices. Logged-in users are managed per account.

③ Completing a Rewarded Ad grants additional free uses. The amount per ad and the daily cap follow in-app notices.

3. Points System

Point Types

Deduction

Free Points are deducted first; Charged Points are used only when Free Points are insufficient. Within the same type, points with the earliest expiry are deducted first. Until charged points go on sale, Free Points are the only point type offered and all deductions are made from Free Points. If points are incorrectly deducted due to a service error, we will restore them (contact brisense@daum.net).

Point Validity

Charged Points are valid for 365 days from the date credited. Expired points are forfeited and cannot be restored. No validity period currently applies to Free Points. The Service may introduce one, in which case it will take effect only after amendment of these Terms under Article 3 of the Korean version and prior notice.

Account Deletion, Service Termination, and Free Grants

Free Points are forfeited on expiry or on account deletion and are not refundable. If you still hold points purchased for value when you delete your account, you may use them or request a refund before deletion, following the procedure in Section 4 below.

Even after account deletion, transaction records that must be retained under the Act on Consumer Protection in Electronic Commerce and other applicable laws are kept for the period those laws prescribe. The scope and period of such retention, and how user identifiers are handled, are set out in the Privacy Policy.

If the Service is terminated, we will give at least 30 days' notice and refund the unused balance of points purchased for value that are still valid at the time of notice. Refunds follow the procedure of the app market where the payment was made; where that procedure cannot be used, the Service will refund by a separate method announced together with the termination notice.

Points granted free of charge (events, rewarded ads, customer support and the like) were not acquired for value and are not subject to refund, conversion to cash, or transfer — this applies even where the same validity period as Charged Points is applied to them.

Advanced AI Translation Costs

Rare Language (Google Translate)

Rare language translation (shown in-app as "🌐 Google 번역") is charged by text length (independent of the free daily limit), with a maximum of 250 characters per translation.

Server-Side Deduction Logging

When Premium AI or rare language translation is used, an audit log (date, points deducted, user UID or IP) is recorded in Cloudflare KV for 7 days. This enables abuse detection and will support future server-side point balance verification. Where point balances are stored depends on whether you are signed in. When signed in, points are tied to your account and stored on the Service's servers, so they persist across device changes and reinstalls. When not signed in (guest), points are stored only on your device and cannot be recovered if you delete the app or change devices.

4. Paid Services

① The Service sells rechargeable points for in-app use. Product types, prices and point amounts are displayed on the in-app purchase screen. Displayed prices include VAT. Sales begin when the in-app purchase screen is made available; until then no transaction under this Section arises.

② Payments are processed solely through Apple App Store or Google Play in-app purchase. Apple or Google is the party that charges, processes and refunds payments, and the Service may be unable to cancel a payment directly. The Service does not collect or store payment credentials.

③ Users may withdraw a purchase within 7 days of the payment date under the Act on Consumer Protection in Electronic Commerce.

(a) After 7 days from the payment date, a purchase may no longer be withdrawn. However, where the product was not properly provided due to the Service's fault, paragraph ④ applies.
(b) On withdrawal, where points have already been used, the amount corresponding to the remaining points is refunded after deducting the used portion. Paragraph ④ governs the details.

So that users can try Premium AI translation before purchasing, the Service grants free points on sign-up and provides a set number of free translations each day (a measure under Article 17 (6) of the Act on Consumer Protection in Electronic Commerce).

Withdrawal and refund procedures follow the policies and procedures of the app market (Google Play / App Store) where the payment was made. Where the Service cannot execute a cancellation directly, the user may request a refund from that app market, and the Service provides the verification and cooperation needed to process it.

④ Refunds follow each store's refund policy and process. The Service may be unable to cancel a payment directly; where a store refund is unavailable, or the product was not delivered due to the Service's fault, contact brisense@daum.net. Points already used are deducted from any refund. Where the Service refunds directly, it does so within 3 business days of confirming the grounds for the refund. No separate fee is charged for withdrawal of purchase or refund. On refund, the banner-ad-free period granted with that purchase is not recovered.

⑤ A purchase made by a minor without legal guardian consent may be cancelled by the minor or the guardian, except where cancellation is restricted by law. Requests are received at brisense@daum.net; for store payments the applicable store procedure is provided as well.

⑥ If a payment is duplicated or points are not granted due to a Service error, the points will be granted or the payment refunded.

5. Accuracy of Translations

6. Prohibited Uses

• Circumventing daily limits via app reinstallation, VPN, or proxies
• Unauthorized crawling, reverse engineering, or excessive automated requests
• Entering third-party personal or sensitive information without consent
• Requesting translation of illegal or harmful content
• Any activity that disrupts normal service operation

6-1. Responsibility for What You Enter

① To provide translation, what you enter is transmitted to third-party AI and machine translation services. This is inherent to how translation works. We apply safeguards including encryption in transit, no server-side storage, and restricting processing to US-based providers. See the Privacy Policy for details.

② We recommend that you not enter national ID numbers, bank/card numbers, or passwords into the translation box. Such information does not need translating, and omitting it does not limit your use of the service.

③ If you enter another person's personal information, you are responsible for having the necessary authority or consent to do so.

④ Because we do not read or store what you enter, we are not liable for consequences arising from information you choose to enter, absent our willful misconduct or gross negligence.

7. Account Deletion

You may delete your account at any time via Account → Withdraw in the app. Account data (email, name, unique ID) is deleted without delay. However, transaction records that must be retained under applicable laws are kept as set out in Article 6 ⑧ (e); in that case user identifiers are not retained with them.

How point balances are handled depends on where they are stored. Points tied to a signed-in account are forfeited on deletion. Points held by a guest are stored only on the device, are not kept by the Service, and disappear when the app is deleted. Translation history and favourites are not stored on the Service's servers, so they remain on your device regardless of deletion and disappear when the app is removed.

Where points purchased for value are still valid at the time of deletion, Article 6 ⑧ (b) applies.

8. Disclaimers & Limitation of Liability

BriSense is not liable for service interruptions caused by force majeure (natural disasters, DDoS attacks, carrier outages, etc.). The AI translation engine may be changed with prior notice to improve service quality.

9. Governing Law

These Terms are governed by the laws of the Republic of Korea. Any disputes shall be submitted to the jurisdiction of the competent Korean courts.
