This policy applies to the Decoder app and explains how data is handled on HarmonyOS devices.
Decoder does not require account registration and does not collect direct identity information such as your name, phone number, email, location, contacts, or photos.
The app primarily stores settings, analysis records, and the current unfinished analysis state on your device. In addition, after you explicitly tap “Allow” on first launch, the app enables Umeng analytics to send anonymous usage statistics such as page visits, feature taps, and session start/end events to help improve the product.
On the app side we disable non-essential collection such as OAID, device model, operating system version, PLMN, and automatic page capture. However, the third-party SDK may still process the minimum device and network environment information required to provide analytics. Actual handling depends on the SDK capability and the provider's documentation.
To provide a continuous experience, the app stores the following data locally on your device:
This data is stored locally on your device by default and is not automatically synced to a remote server.
The app currently uses the following permissions or system capabilities:
If you do not want haptic or sound feedback, you can disable the related options in the app settings.
Locally stored data is used only to:
After your consent, some anonymous usage statistics are sent to Umeng as a third-party analytics provider for aggregated trend analysis. The app does not sell your personal information and does not directly share your local settings or analysis records with unrelated third parties.
The current version does not provide account services, cloud sync, ads, or social functions. It may enable Umeng analytics after your consent.
Umeng analytics is initialized only after you agree to the relevant consent prompt. Related third-party information is as follows:
Other than the anonymous analytics described above, Decoder does not proactively send your local settings or analysis records to a self-hosted developer server.
You can manage your data in the following ways:
The current version does not provide an in-app option to withdraw analytics consent separately. If you have already agreed, uninstalling the app stops future local collection on that device and removes local retention.
Decoder is available to a broad audience and currently does not provide account registration, social features, or user-generated content. We do not intentionally collect personal identity information from minors.
If future versions add new third-party services, online features, account systems, or other capabilities that require additional explanation, this policy will be updated accordingly. Important changes will be explained in the app or on this legal page.
