Privacy Policy
AI Light Board: LED Sign has no accounts, no ads, and never asks who you are. Last updated August 12, 2026.
What stays on your device
Your saved artworks — their titles, the generated display scripts, thumbnails, and grid sizes — are stored only on your device, in the app's own storage. They are never uploaded to us. Deleting the app deletes them.
What is sent when you create with AI
The AI creation feature is the only part of the app that sends what you typed anywhere. When you send a message in it, these are transmitted to our server and forwarded to our model provider, DeepSeek (with OpenRouter as a fallback if DeepSeek is unreachable), so a display script can be written:
- the text of your message and the earlier messages in that conversation;
- the dot-matrix size and orientation your device is using;
- your app's display language, so the reply is written in it.
No name, email, account, advertising identifier, contacts, photos, or location is attached to that request — we do not ask for them and the app does not have access to them.
Counting your creations
Free creations and paid plans need a way to count, so the app generates a random identifier the first time it runs and stores it in your device's keychain. It is not your Apple Account, not a device identifier, and not linked to advertising — it is a random number whose only job is to keep your remaining creations and any credit pack you bought attached to you rather than to someone else.
Against that identifier our server keeps only counters: how many creations you have left, which plan is active, and how many one-time credits remain. It never holds what you created.
To stop the free allowance from being farmed by deleting and reinstalling, we also use Apple's DeviceCheck, which lets us set a single bit on your device meaning "the free allowance here is used up". That bit carries no information about you and cannot be read by anyone else.
Anonymous usage counts
To know whether the app actually works — whether generated scripts run, whether people finish what they start — we keep daily counts of a small set of events, such as "a script was generated" or "a script failed to run".
- No third-party analytics, tracking, or profiling SDKs are in the app.
- No advertising, and no data is sold or shared with data brokers.
- No cross-app or cross-site tracking.
These are counts and nothing else. Each event increments a number in a daily bucket; no identifier, no IP address, no user agent, and no timestamp beyond the date is stored, so the records cannot be tied back to you or to any single device. Along with the event we record only your App Store country and the app version, which are also stored as counts.
What we do not do
We do not store your conversations on our server. Requests pass through it and the reply is returned to your device. Transient server logs may record ordinary technical information such as error codes and timestamps, used only to keep the service running.
Children
The app is suitable for all ages and asks for no personal information, so it holds none about children or anyone else.
Purchases
Payment is handled entirely by Apple through the App Store. We never see your payment details. The app sends Apple's signed purchase receipt to our server so it can confirm which plan is active; that receipt tells us the product and its expiry date, nothing about you.
Subscriptions renew monthly until cancelled and can be managed or cancelled at any time in your device's Settings. The credit pack is a one-time purchase; because it is a consumable, it lives with the random identifier described above and follows your iCloud Keychain across your devices.
Your rights
We hold no personal data about you, so there is nothing to export. If you want the counters tied to your random identifier deleted, email us and we will remove them; deleting the app and turning off iCloud Keychain has the same practical effect, since a fresh install generates a new identifier. Your artworks are yours to delete at any time inside the app.
Changes
If this policy changes, the updated version will be posted on this page with a new date above.
