Monoware · Lunar Ledger for Android

Privacy policy

Effective November 12, 2026 · Android version 1.0.0

Your subscription ledger lives on your device. You choose what to scan, save, export, and share.

Who is responsible

Monoware develops Lunar Ledger (Android package app.monoware.subscriptionpilot). For privacy questions or requests, contact snailrunrun@gmail.com.

Your ledger

Subscription names, amounts, currencies, dates, payment history, notes, budgets, groups, preferences, and saved import drafts are stored in the app’s private storage. We do not operate a server that receives your ledger. The app does not connect to your bank, read your email or messages, access your contacts, or create an app account. It does not charge subscriptions or cancel services for you.

Images, documents, and scanning

When you choose an image or PDF, or share one into the app, it is read for on-device text recognition using bundled Google ML Kit. Recognized text is parsed locally into suggestions. If rules find no candidate and a compatible system model is already available, on-device Gemini Nano may assist. The app does not download a standalone language model or send receipt images, recognized bill text, or ledger contents to a remote AI service.

Images and PDFs can contain personal or financial information. Only select documents you want to process. Import drafts can retain recognized source text and candidate fields on your device so you can resume review. Suggestions may be incomplete or incorrect; you must check and confirm them before importing. Temporary processing files use local cache storage. Your original files remain with the source app or provider you selected.

Google ML Kit technical data

On-device processing does not mean that every SDK is completely silent on the network. Google ML Kit may collect device and app information, installation identifiers, performance and usage metrics, feature configuration, input and output sizes, event information, and error codes for diagnostics and usage analytics. Its GenAI features may also collect user or device identifiers and configured language information. This technical data is distinct from bill image and text content.

Google states that this technical data is encrypted in transit using HTTPS. Its SDK services and applicable privacy terms govern handling and retention. See ML Kit’s Android data disclosure, ML Kit terms and privacy, and Google’s privacy policy. We do not use advertising SDKs or sell your personal data.

Exports and linked backups

JSON backups can include your subscriptions and bill history; CSV exports contain subscription information. PDF and image reports include the financial information shown in the report. When you share or save an export, or link a backup document, the app or storage provider you choose receives that copy. A cloud document provider may upload it under its own terms. Linked backups are document-based copies, not a Monoware cloud account or automatic real-time multi-device sync. Protect exported files and share them only with recipients you trust.

Permissions and device security

File and photo access is limited to items you select through Android’s system flows or explicitly share. Camera capture, where available, is handled by your selected camera app. Notification permission is used for optional reminders; Android battery settings can delay delivery. Device authentication, when enabled, uses Android’s system credential flow; the app does not receive your PIN or biometric template. You can hide bill details in notifications and widgets. App lock is an access control, not a promise of separately encrypted export files.

Retention and deletion

Your ledger and saved drafts stay in the app’s private storage until you change or remove them, clear app storage in Android settings, or uninstall. Local recovery backups may retain earlier ledger versions; the app keeps up to ten rolling backups per ledger mode. Clearing the app’s storage or uninstalling removes app-private records and backups, subject to Android’s storage behavior. This app disables Android automatic app backup.

Exported files, linked documents, source images, and copies already received by another app are outside the app’s private storage. Delete those separately in the relevant provider or recipient app. There is no Monoware app account to delete. If you email us, we receive your email address and the information you include, use it to answer your request, and retain it as needed for support and legitimate recordkeeping. Please avoid sending sensitive receipts or ledger backups unless necessary.

Children and changes

Lunar Ledger is a general productivity tool and is not directed to children under 13. If you believe a child has sent us personal information, contact us. We may update this policy when the app or its data practices change; the effective date above identifies the current version. For access, correction, deletion, or other privacy requests regarding information you have sent us, email snailrunrun@gmail.com.
