Effective Date: November 15, 2026

These Terms of Service govern your access to and use of the software applications and websites operated by Kestrel Utility Labs, a division of MATHEUS FELICIANO DA COSTA FERREIRA LTDA.

1. License Grant

Subject to these Terms, we grant you a personal, non-exclusive, non-transferable, revocable license to install and use StitchGrid, BowlGram, and CueTape on compatible devices owned or controlled by you. Applications downloaded through the Apple App Store are additionally governed by Apple's Standard Licensed Application End User License Agreement (EULA).

2. Subscriptions, Free Trials & Cancellation

• Auto-renewing weekly and annual subscriptions renew automatically unless canceled at least 24 hours prior to the end of the current billing period or free trial.
• For Apple App Store subscriptions, you can manage or cancel renewal anytime in iOS Settings > Apple Account > Subscriptions, and refund requests are handled directly by Apple Support (`reportaproblem.apple.com`).
• For web subscriptions processed via our Merchant of Record, cancellation and statutory consumer refund inquiries may also be submitted through the billing receipt link or via support@kestrelutilitylabs.com.

3. Professional & Copyright Responsibility

BowlGram provides mathematical cost and ratio calculations; licensed stylists remain solely responsible for patch testing, manufacturer instructions, and salon chemical safety. StitchGrid and CueTape users represent that they hold appropriate permission to rehearse or chart any patterns or scripts loaded on their device.

4. Limitation of Liability

To the maximum extent permitted by applicable law, the software is provided "as is" without warranties of uninterrupted operation, and our aggregate liability shall not exceed the amount paid by you for the applicable application during the preceding twelve (12) months.
