Knotcraft processes everything on your device. We do not collect personal data. We do not have a server for this app. We do not sell data. We do not share it with advertisers.
The only network connection the app opens is to the Apple or Google in-app purchase store, which it contacts when the app starts in order to read the current prices and check what you already own. It contacts the same store again when you buy or restore. That connection is the platform's, not ours: we do not see it, and nothing about you is sent to us by it.
Knotcraft is provided by Nikah AI Ltd, based in the United Kingdom. Governing law: England and Wales.
Nothing that identifies you. There is no operator account and no operator backend. The app contains no analytics SDK, no crash SDK and no advertising SDK.
We do not collect your name, your email address, your location, your device identifiers, your usage patterns, or payment card details.
If you buy Pro inside the app, Apple or Google process the payment. We never see your card details, your store password, or a full payment receipt. The store tells the app whether the product is owned so it can unlock Pro on this device.
Lifetime Pro is a one-time non-consumable purchase at £9.99. It unlocks extra drill packs. The knot library stays free to read.
On your device we store only an entitlement flag (which product ids are owned) so Pro still works in aeroplane mode. Restore purchases re-asks the store; it does not contact the operator.
The app saves the following in its own private storage so that it remembers your choices between sessions:
This data stays on your device. It is not backed up to us, because there is no operator server to back it up to. It may be included in your own device backup if you have one configured — that backup is between you and Apple or Google, and we have no access to it.
You can delete all of it at any time by using the reset control in Settings, or by deleting the app.
The app records that you worked through a drill and confirmed the self-check. It never records a verdict, because it has no classifier and forms no opinion about the knot in your hands.
Knotcraft requests no permissions at all. It does not ask for the camera, the microphone, your location, your contacts, your photos or anything else.
The only third parties involved are Apple and Google. The app asks their store for prices and for what you already own when it starts, and asks again when you buy or restore. They process that under their own privacy policies.
The app bundles no analytics SDK, no crash-reporting SDK, no advertising SDK and no attribution framework. No third party receives usage data from us, because we receive none.
Knotcraft is a knot reference and drill. It is not directed at children under 13, and it is not for unsupervised children. A competent adult should be present whenever a knot is tied in a context that could matter.
We do not collect personal information from anyone, including children. That is our COPPA position: there is no personal information to collect. If you believe a child has provided us with personal information, contact privacy@legalnikahai.com — we will have nothing on our side to delete, and you can delete the app from the device.
We process no personal data about you on our systems. On-device storage of your own settings and records is processing you control on your device, to provide the app you asked for (contract, UK GDPR Article 6(1)(b)).
We share data only with Apple or Google when you purchase or restore, and only as the store requires to complete that transaction. We do not sell personal data.
We retain nothing on our side. On-device data lasts until you reset it or delete the app. Store purchase records are retained by Apple or Google under their policies.
Data-protection law gives you rights to access, correct, export and delete personal data that an organisation holds about you. We hold none, so there is nothing to access, correct, export or delete on our side. The data on your device is yours, and you can delete it yourself at any time as described above.
You may also complain to the Information Commissioner's Office (ico.org.uk).
We do not transfer your data, because we do not receive it. A purchase is a transaction between you and Apple or Google.
There is no operator server for this app. Settings and entitlements are stored in the app's private storage on your device. We do not claim encryption beyond what the operating system provides.
We will post changes here and update the date above. Material changes will be described in the app's release notes.
