NibLedger Privacy Policy

Your pens, inks, fill sessions, amount corrections, cleaning records, notes, and audit history stay on your device. The only network feature is feedback you choose to submit.

NibLedger

Private fountain-pen ledger

The short version

Your NibLedger records are stored in the app's private container on your iPhone or iPad.

Optional feedback sends only the message, diagnostics, contact address, and screenshots you choose.

You can edit records, export or restore a backup, clear the ledger, or remove the app whenever you choose.

Pen and Ink Data NibLedger Handles

NibLedger stores the pen brands, models, nibs, filling systems, colors, acquisition dates, ink brands, names, color families, properties, bottle amounts, fill sessions, amount corrections, cleaning records, and notes that you enter. These facts are used only to organize your private fountain-pen ledger.

Local Storage

Your ledger is stored locally in NibLedger's private app container on your iPhone or iPad. NibLedger has no account, cloud sync, advertising, or analytics and does not upload the ledger to ApplyAI servers.

Backups, Imports, and Sharing

Readable text, pen CSV, ink CSV, event CSV, and checksum-verified JSON backups are created only when you request them. You choose where to save or share each file. NibLedger reads an import only after you select it, previews its contents, and validates its schema, checksum, references, and amount invariants before merging or replacing local records.

Optional Feedback

If you submit in-app feedback, NibLedger sends your message, optional email address, selected screenshots, app version, operating-system version, device model, locale, and App Attest security proof to the ApplyAI support service. We use this information only for support, defect investigation, abuse prevention, and app improvement.

Selected Screenshots

NibLedger can access only images you explicitly select with Apple's system photo picker for a feedback report. Removing or cancelling a feedback draft requests deletion of uploaded draft screenshots; unattached draft uploads are automatically removed after 24 hours.

Diagnostics and App Attest

NibLedger includes no third-party analytics or advertising SDK. App Attest supplies app and device integrity evidence for optional feedback submissions and is used for abuse prevention, not cross-app tracking.

Paid App Store Download

NibLedger is a USD 0.99 paid App Store download, with Apple-equivalent prices in other regions. Apple completes the purchase before installation. The app contains no in-app purchase, subscription, paywall, receipt, or transaction verification, so NibLedger sends ApplyAI no purchase data.

Retention and Deletion

Local NibLedger data remains until you clear it, replace it with an import, or remove the app. Exported files remain wherever you chose to save them. Submitted feedback is kept only as reasonably needed to respond, investigate defects, prevent abuse, and meet legal obligations.

Permissions

The core ledger requires no camera, contacts, location, microphone, notification, photo-library, or account access. Apple's system photo picker appears only when you choose a feedback screenshot, so NibLedger does not receive broad photo-library access.

Children

NibLedger is a general-audience utility and is not directed to children. We do not knowingly collect personal information from children.

Policy Changes

We may update this policy when NibLedger or its data practices change. The current version will remain available on this page with a revised update date.
