PrimiLab Third-Party Personal Information Sharing List
Effective date: 2026-08-24 · Last updated: 2026-09-08
This list accompanies the PrimiLab Privacy Policy. It sets out, item by item, how the "Micca" app (the "App") shares personal information with third parties in order to deliver the corresponding functions, including the name of each third party, the types of information shared, the purpose of sharing and how it is shared.
Third-party SDKs are operated independently by their providers, and their personal-information processing is governed by their officially published privacy policies. We provide data to third parties only within a reasonable and necessary scope, sign data-processing agreements with entrusted processors, and assess and supervise their processing activities.
The types of personal information we collect are described separately in the Personal Information Collection List.
1. Third-Party SDKs Integrated
| Third party / SDK | Personal information shared | Purpose | How it is shared |
|---|---|---|---|
| Tencent Weixin Open Platform mobile SDK (via the fluwx plugin) | Operator: Tencent Technology (Shenzhen) Co., Ltd. | Device information, network information; your WeChat authorization code | To launch the WeChat client for authorization when you choose "log in with WeChat", and to complete sharing when you actively share content to WeChat | Collected on-device by the SDK and transmitted to the third party's servers |
| Umeng+ analytics SDK (umeng_common_sdk) | Operator: Umeng Tongxin (Beijing) Technology Co., Ltd. | OAID (anonymous device identifier), GAID (Google Advertising ID, only on Android devices with Google Mobile Services), device and operating system information, network information, crash and usage records | Initialized after you agree to the Privacy Policy, for usage analytics and crash attribution to improve product stability and experience; not used for targeted marketing, user profiling or personalized advertising | Collected on-device by the SDK and transmitted to the third party's servers; while the app is silent or in the background, cached analytics or crash data may be uploaded and OAID / GAID may be read again to complete an analytics session, without expanding the types collected |
| Volcengine Object Storage (TOS) | Operator: Beijing Volcano Engine Technology Co., Ltd. | Images, videos, audio and sticker files you actively upload | To store the content you upload and serve it when you and your collection members view it | Transmitted by our servers via the provider's API |
| Volcengine SMS service | Operator: Beijing Volcano Engine Technology Co., Ltd. | Your mobile phone number | To send the verification code when you choose phone-code login (your number is passed to basic telecom carriers for delivery) | Transmitted by our servers via the provider's API |
| Google Play services location (the underlying dependency of the geolocator plugin on some Android devices) | Operator: Google LLC | Device and network information required for positioning | To obtain approximate location after you grant the location permission, for the optional place record on a sticker | Invoked on-device by the system service |
Note on location: on Android devices without Google Mobile Services pre-installed (such as Huawei devices), the App automatically falls back to the system's own network location provider and does not depend on Google Play services; no information is shared with Google in that case.
For each third party's personal-information processing rules, please consult the privacy policy published on its official website. You may refuse the function corresponding to any SDK, but that function may become unavailable as a result.
While silent or in the background: apart from the Umeng+ analytics SDK possibly uploading cached data and reading OAID / GAID again, the other third parties in the table process personal information only when you actively use the corresponding function. They do not, while silent or in the background, collect IMEI, IMSI, device MAC address, location, contacts, call logs, calendar, SMS, the device phone number, photos or audio/video on their own.
SDK launch behaviour: except when you actively choose "Log in with WeChat" or "Share to WeChat" and the Weixin Open Platform SDK launches the WeChat client, the third-party SDKs in this app do not self-start or associate-start other apps without a reasonable use scenario.
2. On-Device Processing With No Third Party Involved
Subject cutout for stickers (separating the subject from a photo) is performed on your device by a model bundled inside the App. It works entirely offline, uploads no images, and provides no images or the personal information within them to any third party. Device physical orientation (portrait/landscape or rotation state) is read only on-device when you enter the capture screen, to correct the preview and the captured result; it is not uploaded and is not provided to any third party.
3. Other Circumstances of Sharing
Apart from the entrusted processors above, we share your personal information only in the following circumstances:
- •With your prior explicit consent;
- •Where necessary to respond to a public health emergency or, in an emergency, to protect your life, health or property;
- •As required by laws, regulations, regulators or government-authorized agencies;
- •In transactions such as mergers, acquisitions or asset transfers, where the transferee must continue to perform the obligations under this list and the Privacy Policy; otherwise we will require it to obtain your consent anew.
4. Our Commitments
