Privacy Policy

Last updated: June 15, 2026

Important: STIL., STIL.TOON, STIL.BIZ, and STIL.RECEIPT are apps with no account and no sign-up. We collect no personal information whatsoever. Photos, videos, generated illustrations, business cards, and receipts are all processed on your device or inside your browser.

1. Scope

This Privacy Policy applies to the following products in the STIL. family:

  • STIL. (iOS app and web version at stil.photo)
  • STIL.TOON (iOS app)
  • STIL.BIZ (iOS app)
  • STIL.RECEIPT (iOS app)

2. We Collect No Personal Information

The Service has no account or login feature. We never register or collect your email address, name, or any other personal information in order for you to use it.

No sign-up or sign-in is required. Open the app or the browser and every feature is ready to use.

3. How We Handle Your Data

The following data is never sent to or stored on our servers. It is kept only on your device, inside your browser, or optionally in your Apple iCloud account.

  • Uploaded or selected videos and photos
  • Extracted frame images (STIL.)
  • Detected face positions and features (STIL.TOON)
  • Illustrations generated by Apple Intelligence (STIL.TOON)
  • Captured business card images, recognized fields, and face photos (STIL.BIZ)
  • Library project data
  • Captured receipt and invoice images and recognized fields (STIL.RECEIPT)

4. On-device Processing

All media analysis, editing, and generation is completed entirely on your device or inside your browser.

STIL. — best-frame extraction from video

The iOS app uses Vision Framework, Core ML (PiperSR), and the Apple Neural Engine. The web version runs ffmpeg.wasm and IndexedDB inside the browser.

STIL.TOON — turning faces into illustrations

Face detection (Vision Framework) and illustration generation (Image Playground SDK / Apple Intelligence) are both run on-device. No image is sent to Apple, our servers, or any third party.

STIL.BIZ — scanning and managing business cards

Cards are captured with VNDocumentCameraViewController, recognized via Vision Framework (OCR), and sorted into fields by Apple Intelligence (Image Playground SDK). All processing happens on your device and nothing is sent to our servers.

STIL.RECEIPT — reading and organizing receipts

Receipts are captured with VNDocumentCameraViewController, recognized via Vision Framework (OCR), and sorted into fields by Apple Intelligence. All processing happens on your device and nothing is sent to our servers.

Apple Intelligence requires a compatible device (iPhone 15 Pro and later). On unsupported devices, each app falls back automatically (STIL.TOON uses face stamps; STIL.BIZ and STIL.RECEIPT use rule-based sorting).

5. Photos and Face Data (STIL.TOON)

STIL.TOON is designed to let you share photos with privacy in mind by replacing faces with illustrations. While especially optimized for parents who want to safely share photos of their children on social media, the feature works for faces of any age.

  • Face detection is performed on-device using Apple's Vision Framework.
  • Face illustration is generated on-device using Apple Intelligence (Image Playground SDK).
  • Original photos, detected face data, and generated illustrations are never sent to or stored on our servers.

Generated images leave your device only when you explicitly save them to your photo library or share them through the system share sheet. These actions are always initiated by you.

6. Business Card Data (STIL.BIZ)

STIL.BIZ scans business cards and reads and organizes them on-device. Every step below happens entirely on your iPhone and is never sent to our servers.

  • Capture — Continuous scanning in a single session via VNDocumentCameraViewController. Skew and distortion are automatically corrected by Vision Framework.
  • Text recognition (OCR) — Performed on-device by Vision Framework.
  • Field sorting — Performed on-device by Apple Intelligence (Image Playground SDK). On unsupported devices, the app falls back to rule-based sorting.
  • Storage — Card images, recognized fields, and face photos (Pro) are stored in a local database. They are never sent to or stored on our servers.
  • Add to iOS Contacts / vCard export and import (Pro) — All initiated by your explicit action. Card data only leaves your device when you choose to send it.
About third-party personal information

Business cards contain personal information of third parties (such as your business contacts) — names, organizations, and contact details. Please treat this data as something you manage for legitimate business purposes, in compliance with applicable laws (the APPI in Japan, the GDPR in the EU, and equivalents in other regions).

7. Receipt and Invoice Data (STIL.RECEIPT)

STIL.RECEIPT scans receipts and invoices and reads and organizes them on-device. Every step below happens entirely on your iPhone and is never sent to our servers.

  • Capture — The camera is used only to photograph receipts and invoices. Skew and distortion are automatically corrected by Vision Framework.
  • Text recognition (OCR) — Performed on-device by Vision Framework.
  • Field sorting — Performed on-device by Apple Intelligence. On unsupported devices, the app falls back to rule-based sorting.
  • Storage — Receipt images and recognized fields (date, amount, store, tax breakdown, invoice registration number, and more) are stored in a local database. They are never sent to or stored on our servers.
  • Export and sharing (Pro) — CSV for accounting software, the electronic-bookkeeping set (ZIP), and sharing to the cloud or email are all initiated by your explicit action. Data only leaves your device when you choose to send it.
  • iCloud sync and encrypted backup (Pro) — iCloud sync is tied to your Apple ID and managed by Apple. The encryption key for backups is held by you; we never access their contents.

8. Third-Party Services

The Service relies on the following Apple systems. We operate no servers or databases of our own.

Apple (App Store / StoreKit / iCloud) — used for STIL.TOON Pro, STIL.BIZ Pro, and STIL.RECEIPT Pro billing (StoreKit 2), and optional library, business-card, and receipt data sync across devices (iCloud). All are tied to your Apple ID and managed by Apple; we never hold or access this data.

Please refer to Apple's website for their privacy policy.
