<details>

<summary><sup><mark style="color:blue;">#data difference</mark></sup><br>Why is WISEAPP<strong>・</strong>RETAIL data different from our internal data?</summary>

WISEAPP and WISERETAIL data are based on statistical estimates derived from sample panels.

Differences may occur depending on panel characteristics, analysis algorithms, measurement standards, and other conditions.

</details>

<details>

</details>

<details>

<summary><sup><mark style="color:blue;">#Industry</mark></sup><br>What is the standard for industry classification?</summary>

WISEAPP and WISERETAIL classify industries based on app usage behavior and retail brand payment behavior, respectively.

Because one focuses on digital usage behavior and the other on online/offline payment behavior, the classification systems are different.

</details>

<details>

### WISEAPP: App Market Intelligence <a href="#wiseapp" id="wiseapp"></a>

<details>

<summary><sup><mark style="color:blue;">#survey panel</mark></sup><br>Who is included in your survey panel?</summary>

The survey target is Korean smartphone users, meaning people with Korean nationality who use smartphones either in Korea or abroad.

Foreign nationals are not included in the panel.

</details>

<details>

<summary><sup><mark style="color:blue;">#website traffic</mark></sup><br>Do you provide website traffic analysis?</summary>

No. We only analyze mobile app usage data.\
Website traffic analysis is not provided.

</details>

<details>

<summary><sup><mark style="color:blue;">#OS availability</mark></sup><br>Only Android apps are shown. Where is the iOS app?</summary>

**1) Android Only App**\
Apps developed solely for Android without a corresponding iOS version will only be represented in Android data.

**2) The iOS app has not been linked yet**\
If the app name is different or the release schedule is different, the iOS app may not yet be linked to the Android app.\
Please contact us and we will link it for you.

<a href="https://www.wiseapp.co.kr/contact" class="button primary">Contact</a>

</details>

<details>

<summary><sup><mark style="color:blue;">#iOS only app</mark></sup><br>What about apps that exist only on iOS?</summary>

Due to Apple’s privacy policy, it is difficult to collect iOS user data.\
Therefore, WISEAPP estimates iOS usage data based on Android data, OS market share, and demographic information.

If an app is not available on Android, we cannot provide data for it.

</details>

<details>

<summary><sup><mark style="color:blue;">#indicators by app version</mark></sup><br>Do you provide indicators by app version?</summary>

No. We do not provide indicators by app version because they cannot be measured reliably.

</details>

<details>

<summary><sup><mark style="color:blue;">#specific in-app indicators</mark></sup><br>Do you provide indicators for specific screens or features inside an app?</summary>

No. We do not provide metrics for specific screens or features inside an app.

Apps have many screens and features that change frequently and differently for each user, making it difficult to provide stable and reliable metrics.

</details>

### WISERETAIL: Retail Market Intelligence <a href="#wiseretail" id="wiseretail"></a>

<details>

<summary><sup><mark style="color:blue;">#data adjustment</mark></sup><br>Why is daily data adjusted when monthly data is updated?</summary>

Daily data published during an ongoing month is preliminary. After the month ends, monthly data is updated on the 4th business day of the following month, and the related daily data is recalculated and updated accordingly.

This adjustment reflects:

* confirmation of the monthly reference population (i.e., total payment amount by Korean consumers),
* canceled transactions, and
* delayed transaction records received after the initial daily estimate.

Therefore, daily data shown during the month should be viewed as provisional, while the recalculated figures released with the monthly data should be regarded as the latest confirmed figures available at that time.

[Data Correction Timing](/lang/eng/wiseretail/data-methodology/data-correction-timing.md)

</details>

<details>

<summary><sup><mark style="color:blue;">#data adjustment</mark></sup><br>Why does the sum of daily payment data differ from the monthly data?</summary>

WISERETAIL performs regular monthly data corrections.\
When monthly data is finalized, the daily data for that period is also corrected accordingly, so the corrected daily sum and the monthly data will match.

However, if you compare uncorrected daily data with finalized monthly data, differences may occur.\
For period-to-period comparisons, please always use the corrected data.

Uncorrected daily data should be considered provisional estimates for trend analysis only.

[Data Correction Timing](/lang/eng/wiseretail/data-methodology/data-correction-timing.md)

</details>

<details>

<summary><sup><mark style="color:blue;">#period-over-period comparison</mark></sup><br>Why doesn’t the sum of daily payment counts match the monthly payment count?</summary>

For the Total Number of Payments indicator, the sum of daily data may not match the monthly data.\
This is because daily data and monthly data are calculated using different independent algorithms.

</details>

<details>

<summary><sup><mark style="color:blue;">#payment recognition</mark></sup><br>Why can’t some retail brands be separated even though multiple names appear in payment records?</summary>

WISERETAIL classifies data based on the brand names shown in payment records.\
However, if multiple names appear or the brand identity is unclear, they may be grouped together (e.g., Naver/Naver Pay).

</details>

<details>

<summary><sup><mark style="color:blue;">#payment recognition</mark></sup><br>Where is the payment counted if the user paid after searching on a portal?</summary>

The payment amount is counted toward the brand where the payment was actually completed.

For example, if a user searches on Naver or Google and then moves to the brand’s official store and makes a payment, it is counted toward that brand.\
However, if the payment is made within a portal’s own shopping service (e.g., Naver Smart Store), it is counted toward that platform.

</details>

<details>

<summary><sup><mark style="color:blue;">#specific indicators of a retail brand</mark></sup><br>Do you provide indicators for specific products or sub-categories?</summary>

No. WISERETAIL does not provide metrics for specific products or detailed categories.\
Since WISERETAIL only recognizes the final payment record, it is not possible to provide reliable product-level metrics.

</details>
