Local data
Work text, manually entered names/events/dates, colours, millimetre placement, font/decoration/print settings, templates and favourites stay in private app storage. Rendering, PDF and PNG generation run on-device. Contents are not sent to the developer or Google servers. No camera, microphone, location, contacts or broad photo access.
Files and printing
Only explicitly chosen JSON files are imported. Export, share and print actions send selected PDF/PNG/JSON to the destination or Android print service with temporary read permission. Destination policies apply.
Deletion and backup
Delete works using their menu. Android app-data clearing or uninstall deletes local data. Exported files must be deleted at the destination. Cloud/device-transfer backup and iCloud synchronization are disabled.
Billing SDK
Google Play Billing 9.1.0 sends purchase/restore information, technical connection/API diagnostics, app/OS/library versions and client/session identifiers to Google over HTTPS. No advertising ID, ad SDK, developer analytics SDK or server is used. Work contents are not passed to Billing. Google handles payment details, retention and deletion.
Purchases and sample
Only verified Play purchases grant entitlement; pending purchases do not. The independent fictional sample uses separate memory storage and leaves normal data, settings and purchase rights unchanged.
