LED Spark1. Who this applies to
This page is for users of the LED Spark app on Android, iPhone, and iPad, published by YAYIN INTERNATIONAL TRADING LIMITED. LED Spark has no user accounts, so there is no account to close; deletion is handled per installation.
2. Delete what is on your device — immediately, no request needed
Uninstall LED Spark, or clear its data (Android: Settings → Apps → LED SPARK → Storage → Clear storage). This removes your saved works, preferences, the cached subscription status, and the random installation identifier. Your signs are never uploaded, so nothing else holds them. A reinstall gets a new installation identifier, which is not linked to your earlier use; on Android, Adjust may still recognise the device through its advertising ID until you reset it, and a restored subscription carries the store’s purchase references.
3. Ask us to delete reported records
Email contact@yayinintl.com with the subject “LED Spark Data Deletion Request”. Include the platform (Android or iPhone/iPad), the approximate date you installed LED Spark, and — if it is still installed — the date and time you last opened it. We usually reply within a few business days and confirm when deletion is complete. If you can, send the request before uninstalling: once the app is removed, its installation identifier is gone and matching your records is harder.
4. What is deleted
On a verified request we delete, or ask our processors to delete, the usage-analytics and install-attribution records associated with your installation. This covers records held by Yayin Guanjia and the corresponding records in Google Firebase Analytics and Adjust.
5. What is kept
Subscription and payment records are held by Google Play or the App Store, not by us; manage them through your Google or Apple account. We may keep a record of the deletion request itself, and information we must retain for tax or accounting purposes, for as long as the law requires. Records not deleted on request are retained by the processors under their own retention periods, as described in the Privacy Policy.
6. Stop future collection
Turn usage analytics off in Me → Settings → About → Usage statistics. On Android you can also delete or reset your advertising ID in your device settings. See the Privacy Policy for details.
