ThreadKit is an independently developed iOS app published by XUEDONG TIAN ("we", "us"). For any privacy question you can reach us at txd027@126.com.
Manage knitting, crochet and sewing projects with progress tracking.
The information the app works with is created by you and stored locally:
This data lives in the app's own storage on your iPhone or iPad. It is never uploaded to us or to any third party, and we have no way to access it.
| Category | Collected? |
|---|---|
| Contact information | No |
| Identifiers (user ID, device ID) | No |
| Usage data / analytics | No |
| Diagnostics / crash data sent to us | No |
| Location | No |
| Purchases | No (the app is free, there are no in-app purchases) |
| Content you create in the app | Stored on your device only — not collected by us |
Photo library / camera (only when you attach a picture to a project) — the image is stored locally on your device.
Permissions are optional: if you decline, the app still works, only the related feature is unavailable.
The app contains no advertising SDK, no analytics SDK and no third-party tracking. It does not connect to any server operated by us.
The app is not directed to children under 13 and we do not knowingly collect any information from anyone, including children.
You are always in control. Delete individual entries inside the app, or delete the app from your device to remove all of its data at once. Because nothing is stored on our side, there is nothing for us to delete on your behalf.
Data remains on your device for as long as you keep it. We hold no copy and therefore have no retention period to apply.
If this policy changes, the updated version will be published at this address with a new "last updated" date.
