Version: 2026-10-08
Effective date: October 8, 2026
Last updated: October 8, 2026

The operator of Pieceful ("Pieceful," "we," or "us") provides an app that helps parents record a child's everyday moments in photos, audio, and text and organize them into stories on this iPhone. This policy explains the information we process, why we process it, and how it is retained and deleted.

1. Information we process

CategoryInformationSource
Family recordsNormalized app-owned JPEG copies of directly attached photos and profile photos, audio recordings, text records, and a child's name, birthday, and profile-photo referenceInformation entered or selected by the user
Photo contextPhotoKit localIdentifier for automatic photo cards without copying original pixels, capture time, andโ€”only after separate consentโ€”GPS coordinates and a derived place nameThe user's iOS Photos library
Account informationOnly when the user signs in to bring over records from the earlier Pieceful, delete that server account and its data, export server data, or secure that account: Firebase user identifier, Google, Apple, or legacy email sign-in provider, an email supplied by the provider (which may be an Apple private relay address), email-verification state, and account creation timeUser, Google, Apple, and Firebase Authentication
Account governancePolicy type, version, locale, acceptance time, app version, platform, account status, reason code, user-facing message, and enforcement periodApp and Pieceful operator
Security audit dataRequest identifier, HMAC identifiers for the operator and target account, role, action, reason, before/after state, and time. Operators are prohibited from entering email, UID, child data, or family-record content in internal notesPieceful admin tool
Analytics and diagnosticsOnly when the user turns on Share usage information to improve the app: hashed user/record identifiers, product interaction events, crash data, and performance dataApp, Firebase, and Mixpanel

Pieceful does not collect advertising identifiers or sell personal information. We do not store, analyze, or log passwords, authentication tokens, or Google or Apple authorization codes.

2. Purposes of processing

  • Create, store, search, export, and delete photo, audio, and text records
  • Suggest story details, turn audio into text, and group photo moments, all of which happen only on this iPhone
  • Provide record and story notifications selected by the user
  • Authenticate Google and Apple accounts to bring over records from the earlier Pieceful, delete the server account and its data, and export server data, and recover or secure legacy email accounts
  • Prevent duplicate requests and abuse of account features
  • Verify versions of required terms and privacy policies and retain proof of acceptance
  • Apply account restrictions, notify users, handle appeals, and respond to security incidents
  • Improve quality using pseudonymized analytics and diagnostics when the user has turned on usage sharing

3. Children's information and family records

Pieceful processes records that a parent creates about a child.

  • Family records remain in Pieceful's protected storage on the device. If iCloud is available, they sync to the user's private iCloud database (iCloud.com.pieceful.native).
  • Direct attachments, profile photos, and audio may be normalized and stored as size-limited app-owned files or CloudKit assets. Pieceful does not modify or delete originals in Photos.
  • Story suggestions, audio-to-text, and photo-moment grouping are all processed on this iPhone. The photo, audio, and text content of a record is not sent to Pieceful or to an AI provider.
  • On an iPhone that supports Apple Intelligence (iOS 26 or later, iPhone 15 Pro or later, Apple Intelligence turned on), the system's on-device language model suggests a topic, a title, and a one-sentence summary for one saved record when the user opens Add to a story. Nothing is saved until the user confirms or edits it. On other iPhones the user writes the title and text and picks the topic without suggestions.
  • Audio-to-text uses Apple's on-device speech recognition (supported devices on iOS 26 or later) and does not upload the recording. Unsupported devices keep the recording as audio.
  • Photo moments are grouped by a rule that compares capture time and, if present, location in device memory only. Photo data, capture time, and location are not sent to Pieceful or to an AI provider. A place name for a photo card is derived with the reverse geocoding Apple provides in iOS, and only after the user turns on the photo-location setting in Profile.
  • Pieceful does not collect information directly from children. A parent can use the rights described below for a child's records.

None of the features above needs an account, and new users never need to sign in. Google and Apple sign-in form the control-plane boundary used only to bring over records from the earlier Pieceful, delete that server account and its data, export server data, and manage security for that account. Family records created in this app are not moved into Pieceful's general API content database.

If you still use the earlier version (2.x)

This policy applies to Pieceful 3.0.0 and later. Pieceful 2.x, the version before the 3.0.0 update, stores the photos, audio, and text you record on Pieceful servers (Google Cloud and Supabase) and processes them with Vertex AI (Gemini) on Google Cloud to organize and summarize records. That server storage and AI processing happen only while you use 2.x and stop with 3.0.0. Records that 2.x stored on the server can be brought to your device, exported, or deleted together with the account after signing in on 3.0.0.

4. Retention and deletion

InformationRetention
Device/private CloudKit family records and app-owned mediaUntil the user deletes them or completes Pieceful account and data deletion
Firebase account data and server account metadataUntil account deletion completes
Policy acceptance receipts and current account statusUntil account deletion completes

| Pseudonymous account-enforcement security audit | Three years after the action; longer only while a dispute or legal hold remains, then deleted |

| Mixpanel analytics events | Up to five years after collection |

| Firebase diagnostics | The configured Firebase project retention period or until an applicable deletion request is processed |

| One-way account-deletion write-fence hash | Only as long as needed to prevent restoration of deleted data, no more than three years |

When a retention purpose ends, electronic files are deleted so that recovery is impracticable. Records required by law are separated, not reused for unrelated purposes, and deleted when the required period ends.

  • Delete all app data deletes Pieceful records and app-owned media on the device and in the user's private CloudKit database.
  • Delete Pieceful account and data verifies recent sign-in, then deletes those records, the account, server metadata, policy receipts, and current account state. For Apple accounts, Pieceful also attempts token revocation when possible.
  • Security audit records contain a server-secret HMAC instead of a raw UID and are separated from ordinary account data, then removed through a dedicated retention process after the period above.
  • Original Photos assets are outside Pieceful account deletion. App Store purchase history is managed by Apple and cannot be deleted by Pieceful.

5. Processors and international transfers

We use the providers below to operate the service. Transfers occur over encrypted connections as the service is used. Information is deleted under this policy or the applicable provider's retention controls.

ProviderService and informationProcessing location
Google LLC (Firebase Authentication, App Check, Analytics, Crashlytics, Remote Config)Account identifier and email authentication for signed-in accounts, app integrity, and remote configuration. Interaction events and diagnostics only when usage sharing is onUnited States and other Google infrastructure locations
Supabase, Inc.Policy receipts, account state, and HMAC security audit storage for signed-in accounts. Text and metadata of records made in the earlier version (2.x)United States and other Supabase infrastructure locations
Google LLC (Google Cloud Storage, Vertex AI)Server storage and AI processing of photos, audio, and text recorded in the earlier version (2.x). Version 3.0.0 and later send nothing new; only records kept for import, export, and deletion remainRepublic of Korea, the United States, and other Google infrastructure locations
Mixpanel, Inc.Hashed identifiers and product interaction analytics, only when usage sharing is onUnited States
Apple Inc.Sign in with Apple, App Store purchase processing, and the user's private CloudKit storageUnited States and other Apple infrastructure locations

Users who do not want an international transfer may use the app without connecting an account and with optional usage sharing left off, or delete an account they have already connected. Refusing a transfer required for authentication or storage can make the corresponding feature unavailable.

6. Your rights

You may request access, correction, deletion, restriction, or withdrawal of consent at any time. Use the account security, export, and deletion controls in the app or email kimsol@solmatter.kr. We verify the requester and respond as required by applicable law.

Policy access, export, account deletion, sign-out, and an appeal channel remain available even when an account is restricted, suspended, terminated, or missing policy acceptance. Appeal an account action at kimsol@solmatter.kr.

7. Security

  • Pieceful uses complete file protection on the device and the user's private CloudKit database for sync.
  • Account APIs validate Firebase ID tokens and App Check. Business operations also verify current policy acceptance and account status.
  • Operator and target identifiers are pseudonymized with a server-secret HMAC. Analytics identifiers are minimized after SHA-256 hashing.
  • If the server policy version and SHA-256 do not match the bundled app document, account-based business operations fail closed while export and deletion remain.
  • The admin tool uses least privilege, role separation, confirmation, and an immutable audit trail. It cannot display child records, photos, audio, or text.
  • Unexpected persistence failures fail closed, and application logs exclude authentication secrets and raw personal information.

8. Changes to this policy

We provide at least seven days' notice of material changes in the app or on the public policy page. Changes that materially affect user rights, such as new purposes, categories, or disclosures, receive at least 30 days' notice and a new confirmation or consent when required. Previous versions and effective dates are kept in the publication record.
