Controller

This policy is provided by Guangxi Laitelin Network Technology Co., Ltd. (“we”). The name matches what is shown on app stores and developer consoles. For questions, use in‑app feedback or store developer contacts.

We explain how we collect, use, store, and share personal information and what rights you have.

1. What we collect and why

1. Device and logs: device model, OS version, IP address, crash logs, etc., for security and analytics.

2. Advertising: third‑party ad SDKs may collect device and usage data needed for delivery and fraud prevention, as described in their policies.

Note: We do not proactively read or store your contacts, SMS, or call logs. If we ever need sensitive permissions, we will ask again in the app and update this policy.

2. Third‑party SDKs

For ads, attribution, and stability we integrate SDKs listed below (aligned with national registry where applicable). On Android we have removed unnecessary sensitive permission declarations from ad SDKs where technically possible. We do not provide contacts, SMS, or call content to these SDKs.

5. Sharing

We do not sell your personal information. We may disclose data only with your consent, when required by law, or to protect rights and safety as permitted by law.

6. Your rights

Access and correct personal information you provide in the app (if any);
Withdraw consent where feasible.

7. Policy changes

We may update this policy; material changes will be highlighted in the app. Continued use means acceptance.

For questions, contact us via in‑app feedback or app store developer contacts.
