LED Spark1. Agreement
These terms govern your use of LED Spark. By using the app, you agree to these terms and to use the app lawfully and responsibly.
2. Product purpose
LED Spark is a creative utility for making and displaying glowing text signs, glow sticks, and cheer lights, managing works on your device, and exporting supported media formats. Use of the app requires an LED Spark Pro subscription, except where a limited free tier is offered.
3. Your content
You keep responsibility for words and designs you create. Do not display unlawful, infringing, deceptive, hateful, harassing, dangerous, or privacy-invasive content.
4. Public and safety-sensitive use
You are responsible for brightness, motion, placement, audience consent, local venue rules, and safe device handling. Flashing effects may affect people with photosensitivity; use the Reduce flashing setting where appropriate. Do not use the app where flashing effects, distraction, or obstructed vision could create risk, including while driving.
5. Intellectual property
LED Spark software, interface, templates, brand assets, and original visual elements are owned by or licensed to YAYIN INTERNATIONAL TRADING LIMITED. These terms do not transfer ownership of your original words.
6. Exports and third-party rights
You must have the rights needed for any words, images, fonts, marks, or other material you use or distribute. Export availability depends on device and operating-system capabilities.
7. Availability and updates
Features may change for compatibility, safety, reliability, or quality. We do not promise uninterrupted or error-free operation on every device.
8. Subscriptions, trials, and billing
LED Spark Pro is a weekly auto-renewing subscription sold through the app store on your device. It renews automatically until you cancel. A free trial, where the store offers one, is available only to accounts that have not subscribed to LED Spark before; eligibility is decided by the store. Cancelling before a trial ends means you are not charged. The exact price, billing period, and any trial or introductory offer are shown before you confirm a purchase. To cancel, use the subscription settings of your app store account; uninstalling the app does not cancel a subscription. Refunds are handled by the app store under its own policy. Full details are in the Subscription Terms.
9. Liability and consumer rights
Nothing excludes rights or liabilities that cannot legally be excluded, and mandatory consumer protections where you live continue to apply. To the extent permitted by law, we are not responsible for indirect loss arising from unsafe display, unlawful content, or use outside the intended purpose.
10. Changes, operator, and contact
We may update these terms when the app, the law, or store requirements change, and will publish the current version here.
