StackWorks Arika Note stores your entered name, contacts, locations of financial and other paperwork, contractual notes, care preferences, family messages, selected photos, settings and review dates in the app’s private device storage. Secret-like text detection runs locally. No custom server, cloud sync, ads or analytics SDK is used.
Device-wide backup
Participation in device backup is on by default and can be turned off. When OS backup or transfer is enabled, a copy of notes and settings may be sent to the operating system’s chosen backup provider, governed by that provider’s settings and terms. Turning it off removes the future local backup copy; existing provider-side backups must be managed with the provider. Purchase entitlements, temporary PDFs and passwords are excluded. OS backup capacity limits can prevent completion; retain an encrypted export for migration.
Photos, permissions and authentication
Only photos you select are read, resized to a maximum 1600-pixel long side and re-encoded as JPEG without location metadata. No camera, microphone, location, address-book, Health Connect or Accessibility Service is used. Notifications require notification permission. The OS verifies biometric or device credentials; the app never receives them.
Google Play purchases
Google Play Billing 9.1.0 may process purchase history, transaction identifiers, connection/device details, diagnostics and client/session IDs for purchase, restore and verification, using encrypted transport under Google’s policies. No payment-card details or advertising ID are received by the app. Notes, photos and care preferences are not sent to billing.
Exports and deletion
PDFs are made locally, with optional AES-256 password protection. A private preview copy is removed on closing. ARIKAB01 backups use PBKDF2-HMAC-SHA256 (310,000 rounds) and AES-256-GCM; passwords are never saved. You choose recipients, storage and printing. Delete local records in the app, and manage exported copies, print-service copies and OS backups at their respective destinations. Contact contact@stack-works.dev without including actual assets, health data, credentials or backup passwords. Updated October 5, 2026.
