LightDrop

Privacy Policy

Last updated: August 4, 2026

LightDrop moves a file from one screen to one camera. There is no network in between, and there is no company in between either. This policy explains, in plain language, what the app does and does not do with your information.

The short version: LightDrop contains no networking code. It has no account system, no analytics, and no server. We never receive your files, because there is nowhere for them to be sent. We collect no personal data from you.

1. Who we are

LightDrop (the "app") is developed and published by Yangworks ("we," "us," or "our"). This policy applies to the LightDrop app for iPhone, iPad, and Mac, and to this website. If you have any questions, you can reach us at support@tk999.top.

2. Information we do not collect

The notable thing about LightDrop is what it doesn't do. We want to be explicit:

  • No accounts. There is no sign-up or login. We never ask for your name, email address, or phone number to use the app.
  • No analytics or tracking. The app contains no third-party analytics, advertising, or tracking SDKs. We do not use the Advertising Identifier and we do not track you across apps or websites.
  • No file uploads. We operate no server that receives, stores, or processes the files you send. We never see your content.
  • No crash or usage reports. The app sends us nothing at all — not diagnostics, not device identifiers, not a count of how often you open it.

The app's privacy manifest declares no tracking and no collected data types, consistent with this policy. Its App Store privacy label is "Data Not Collected."

3. How a transfer works

The sending device turns your file into a sequence of QR codes and plays them on its screen. The receiving device points its camera at that screen and rebuilds the file from what it sees. That is the entire transport.

  • No network is used. Not Wi-Fi, not Bluetooth, not cellular, not AirDrop, and not a cable. The app works identically in airplane mode or on a device that has never been connected to anything.
  • Nothing is routed through us. There is no relay, no queue, and no temporary storage on any server. The file exists on the sending device, in the light between the two devices, and on the receiving device.
  • Nothing is left behind on our side. Because no data ever reaches us, there is no record of your transfer for us to keep, disclose, or lose.

4. Data stored on your device

Everything the app needs lives on your own device:

  • Files you send and receive. A file you choose to send is read from where you chose it. A file you receive is written where you choose to save it, or to your photo library if you tap Save. The app does not maintain a hidden archive of past transfers.
  • App preferences. Settings such as transfer speed, fragment size, turbo mode, and your language choice are saved locally in the system preferences store. This information stays on your device and is never shared with another app.
  • Purchase state. Whether Pro is unlocked is determined by asking Apple's StoreKit on your device. We store no purchase record ourselves.

Because this data lives only on your device, deleting the app removes it.

5. Device permissions we request

The system asks for your consent before the app can use certain features. We request the minimum needed and use each permission only for its stated purpose:

  • Camera. Used only to decode QR codes while the Scan screen is open. Frames are analysed in memory and discarded immediately. The app never records video, never takes a still photograph, and never writes anything from the camera to disk.
  • Add to Photos. Requested the first time you save a received image to your photo library. It grants only the ability to add. The app cannot read, browse, or delete your existing photos with this permission.
  • Files you pick. When you choose a file to send, the system hands the app that one file. The app has no access to the rest of your storage. On Mac, LightDrop runs inside Apple's App Sandbox, which enforces this.

Notably, LightDrop never asks for Local Network permission — a good sign that it isn't using one.

6. Password encryption

Pro adds an optional password. When you set one, the payload is encrypted on the sending device before the first QR frame is drawn, using AES-GCM from Apple's CryptoKit.

  • The password is used on your device to derive a key. It is never sent to us, never stored on a server, and never embedded in the QR frames.
  • The receiving device asks the person holding it for the same password and decrypts locally. The two devices never exchange the password itself.
  • We cannot recover an encrypted transfer. If the password is lost, the data cannot be decrypted by us or by anyone else — send it again with a password you both know.

7. What a bystander can see

We would rather state the one real limitation plainly than let you discover it: a transfer happens on a screen, in the open. Anyone who can see that screen — a person standing behind you, a security camera, a screen-sharing session — can photograph the same frames your receiver is reading.

If the room isn't private, use a password. With encryption on, recorded frames are useless without the password. Without encryption, treat a transfer the way you would treat holding the document up to the light.

8. Purchases and subscriptions

LightDrop offers a monthly subscription and a one-time "Lifetime" purchase through Apple's In-App Purchase system. Payments are processed by Apple, not by us. We do not receive or store your payment card details.

Apple provides us with aggregated, non-identifying sales and subscription reports so we can operate the business. To make, restore, or manage a purchase, the app relies on Apple's App Store and your Apple Account. Apple's handling of that information is described in Apple's Privacy Policy.

9. Third-party services

The app embeds no third-party analytics, advertising, or social media SDKs. The only third party inherently involved is Apple, which provides the App Store, In-App Purchase, and the operating system services the app runs on. This website is served as static files and sets no tracking cookies.

10. Children's privacy

LightDrop does not target children and does not knowingly collect personal information from anyone, including children. Because the app collects no personal data at all, it does not build profiles of any user regardless of age.

11. Your control and choices

You are always in control of your content:

  • Nothing to request or erase. Rights of access, deletion, and portability all presuppose that a company holds data about you. We hold none, so there is nothing for you to request from us — but you are welcome to write and ask us to confirm that.
  • Delete everything. Deleting the app removes its on-device preferences. Files you already saved stay where you saved them, under your control.
  • Revoke permissions. You can change camera and photo permissions at any time in the system Settings app, on any of your devices, without uninstalling.

12. Changes to this policy

If we update this policy, we will revise the "Last updated" date at the top of this page and post the new version here. Material changes will be reflected on this page before they take effect.
