Privacy Policy

Effective Date: November 15, 2026

Kestrel Utility Labs, operated by MATHEUS FELICIANO DA COSTA FERREIRA LTDA ("Company", "we", "our", or "us"), builds local-first utility applications including StitchGrid, BowlGram, and CueTape. This Privacy Policy explains what data is processed, where it resides, and your rights under GDPR, UK GDPR, CCPA, and LGPD.

1. On-Device Data by Default

Your knitting charts, salon color formulas, barcode catalogs, and self-tape rehearsal recordings are stored locally on your device (and, where enabled by you in iOS Settings, in your private Apple iCloud container). We do not maintain a centralized database of your personal creative files or client records.

2. Optional Assistive Import & Third-Party AI Disclosure

Certain optional import features (such as converting a photo of a printed stitch chart, parsing a chemical supply invoice, or segmenting dialogue lines) send the selected snippet or image over encrypted TLS (`https://api.kestrelutilitylabs.com`) to Google LLC's paid-tier Gemini API solely to return structured JSON to your device.

• Explicit Consent First: No text or image is ever transmitted until you review and accept the in-app Data & AI Permission sheet (Apple App Store Guideline 5.1.2(i)).
• Zero Model Training: Paid-tier API requests are contractually excluded from training foundation models and are discarded immediately after structured extraction.
• Volatile Script Handling (CueTape): Audition scripts rehearsed in CueTape are processed in volatile memory (`RAM`) for dialogue cueing and are never exported or stored on external servers.

3. Subscriptions & Billing

In-app purchases on iOS and iPadOS are processed directly by Apple Inc. via StoreKit 2. Web purchases, where offered, are processed by our authorized Merchant of Record (Paddle.com Market Ltd). We never receive or store raw payment card numbers.

4. Data Deletion & Privacy Requests

Because workspace data resides locally on your device, deleting an item inside the app or uninstalling the app permanently removes local data. You may revoke assistive import consent at any time inside the app's Settings screen or contact our privacy team at support@kestrelutilitylabs.com.
