Kerfwise — Privacy Policy

Kerfwise is an iPhone app published by Mubarak Almahmeed under the MubarakLab brand. This policy describes the data handled by the app and the destinations you choose.

Workshop records stay local

Kerfwise stores saved projects, dimensions, material and stock identities, prices, cut history, notes, optional photographs, preferences, navigation and editor drafts locally on your device. It has no Kerfwise account, developer backend, external AI, analytics, advertising, tracking SDK or automatic developer-operated cloud synchronization.

Camera, Photos, Files and QR labels

Optional camera access lets you attach a stock photograph or read an opaque Kerfwise label. System Photos and Files selection accesses content you choose. Manual fields and local record selection remain available. Photographs are not used to infer dimensions or grain.

Stored photograph copies are normalized and reencoded locally without EXIF, GPS or provider metadata. A scanned label looks up a local piece identity. Lookup does not authorize a cut, change stock or open an arbitrary URL.

Public exports and printing

Plan PDFs, public CSV and labels omit designated private notes, stock locations, photo metadata and provider paths. Public names and notes you entered may appear; selected costs can appear in a PDF. Optional recorded physical history includes identities, times and measurements while omitting private event notes.

Exports are prepared locally. You choose whether to share, print or save them and select the destination. Review the preview and included fields before sharing.

Private backups and destinations you choose

A private .cutbench backup includes saved workshop records, private notes, locations, prices, photographs and physical history. It is not encrypted by Kerfwise. Choose a destination and protect the file accordingly.

The logical backup does not include unsaved editor drafts or the original workshop’s local pending-cut recovery marker. Resolve unsaved physical cuts in the original workshop. Restored stock remains Unverified until physical identity reconciliation.

Files saved to a selected cloud drive or shared through another app follow that destination’s policies. Operating-system backup services follow your device settings. These services may keep copies outside the device even though Kerfwise has no developer-operated sync service.

Managing local data

Archive, Trash and permanent disposal preserve stock identity and consumption trails required by retained records. Deleting a record does not turn a consumed piece into available material.

Explicit storage cleanup can remove unreferenced photograph files and derived thumbnails. Referenced assets and active review or export files are protected during that cleanup. Deleting the app removes local app data unless the operating system or a saved backup provides recovery. Kerfwise makes no additional encryption or file-protection guarantee.

Purchases, website links and support

Apple processes all payments. In version 1.1 and earlier that was the upfront app purchase. From version 1.2, Kerfwise checks Kerfwise Pro, the 7-Day Pro Trial and whether you bought the app while it was paid on your device with Apple’s StoreKit, including the App Store’s record of your original download. MubarakLab never receives payment details or your Apple Account information.

From version 1.2 the app also keeps a few records on your device only, in app storage and the iOS Keychain (set to this device only): when it was first installed and whether data from an earlier version was present, the result of that purchase check, trial timing, when a Kerfwise Pro screen was last shown, rating-request timing and which one-time tips were shown. They decide which plan applies and keep these prompts rare; none of them is sent to MubarakLab or anyone else.

Each page of a free-plan PDF ends with a “Cut plan made with Kerfwise” line and a plain App Store link that contains no identifier for you or your device.

The app does not silently send support diagnostics. Opening a configured support website, privacy policy or email destination requires your explicit action. A browser or email service may receive normal connection or message information under its own policies. Rate Kerfwise opens the App Store review page and More from Mubarak Labs opens Apple’s App Store sheet for another MubarakLab app, only when you tap them; no tracking or campaign identifier is added.

If you email support, the publisher receives the message and any information or attachments you choose to send. Support messages and attachments are retained for 90 days. Review attachments first, especially private backups. For privacy questions or requests about information you have sent, contact almahmeed.dev@gmail.com.
