Looplet Terms of Service

Effective May 24, 2026

Effective date: May 24, 2026 Last updated: May 24, 2026

Please read these Terms of Service ("Terms") carefully before downloading or using Looplet ("the App"). By downloading, installing, or using the App, you agree to be bound by these Terms. If you do not agree, do not use the App.

1. About Looplet

Looplet is a macOS application designed to help crafters organize crochet and knitting patterns, track stitch counts, and use on-device AI assistance for pattern-related tasks. The App is developed and published by Ryan Calpin ("Developer," "we," "us," or "our").

2. Acceptance of Terms

By using Looplet, you confirm that:

  • You are at least 13 years of age (or the minimum age required in your jurisdiction to enter into a binding agreement).
  • You have the legal capacity to enter into these Terms.
  • You are using the App for lawful purposes only.

If you are using the App on behalf of an organization, you represent that you have authority to bind that organization to these Terms.

3. License

We grant you a limited, non-exclusive, non-transferable, revocable license to download and use the App on Apple devices you own or control, solely for personal, non-commercial purposes, in accordance with Apple's App Store Terms of Service and these Terms.

You may not:

  • Copy, modify, distribute, sell, or sublicense the App or any portion of it.
  • Reverse engineer, decompile, or disassemble the App, except as permitted by applicable law.
  • Remove or alter any proprietary notices or labels.
  • Use the App to develop a competing product or service.

4. Free Tier and Pro Upgrade

4.1 Free Tier

The App is available to download at no charge. Free tier users may store up to three (3) patterns in the pattern library concurrently and have access to a limited selection of themes.

4.2 Looplet Pro

Looplet Pro is available as a one-time, non-consumable in-app purchase ("Pro Unlock") that removes the pattern limit and unlocks all themes and future Pro features.

  • Purchases are processed by Apple through the App Store.
  • All purchases are subject to Apple's App Store Terms of Service: https://www.apple.com/legal/internet-services/itunes/
  • All sales are final. Refunds, if any, are handled solely by Apple in accordance with their refund policy.
  • You may restore a previously purchased Pro Unlock at no additional charge by using the "Restore Purchases" option within the App on any device signed into the same Apple ID.

4.3 Price Changes

We reserve the right to change the price of the Pro Unlock at any time. Price changes will not affect purchases already completed.

5. On-Device AI Features

Looplet includes AI-powered features (such as pattern summarization, abbreviation lookup, and step-by-step guidance) powered by Apple's on-device language model framework (FoundationModels / Apple Intelligence).

  • All AI processing occurs entirely on your device. Your pattern text and queries are not transmitted to our servers or any third-party AI service.
  • AI-generated content is provided for informational and creative assistance only. We make no guarantees about the accuracy, completeness, or suitability of AI-generated suggestions.
  • You are solely responsible for reviewing AI output before relying on it for your projects.
  • AI features require a compatible Apple device with Apple Intelligence support. We cannot guarantee availability on all hardware or OS versions.

6. iCloud Sync

The App optionally uses Apple iCloud Key-Value Storage to synchronize your pattern library across devices signed into the same Apple ID.

  • iCloud sync is opt-in and requires you to enable iCloud in Xcode with your own Apple Developer account if you are building from source, or it is handled automatically in a signed distribution build.
  • iCloud data is governed by Apple's iCloud Terms and Conditions: https://www.apple.com/legal/internet-services/icloud/
  • We do not have access to data stored in your iCloud account.
  • In the event of a sync conflict, the App uses a last-writer-wins strategy based on timestamps. We are not responsible for any data loss arising from sync conflicts.

7. Your Content

7.1 Ownership

You retain full ownership of all patterns, notes, and other content you create or import into the App ("Your Content"). We claim no intellectual property rights over Your Content.

7.2 Third-Party Patterns

You are solely responsible for ensuring that any crochet or knitting patterns you import or store comply with applicable copyright law. Looplet is a personal organization tool; it does not grant you any license to reproduce, distribute, or publicly display patterns owned by third parties.

7.3 Storage and Backup

All Your Content is stored locally on your device and, if enabled, in your personal iCloud account. We do not maintain backups of Your Content. You are responsible for maintaining your own backups.

8. Privacy

Our full Privacy Policy is available at ‣. Key points:

  • We do not collect personally identifiable information from the App.
  • The App does not transmit your pattern data to any external server.
  • AI features operate entirely on-device with no data leaving your device.
  • Analytics or crash-reporting tools, if integrated in the future, will be disclosed in an updated Privacy Policy.

9. Intellectual Property

The App, including its design, code, graphics, and documentation, is owned by the Developer and protected by copyright, trademark, and other intellectual property laws. The Looplet name and logo are proprietary to the Developer.

Nothing in these Terms transfers any intellectual property rights to you other than the limited license described in Section 3.

10. Disclaimer of Warranties

THE APP IS PROVIDED "AS IS" AND "AS AVAILABLE" WITHOUT WARRANTIES OF ANY KIND, EXPRESS OR IMPLIED, INCLUDING BUT NOT LIMITED TO WARRANTIES OF MERCHANTABILITY, FITNESS FOR A PARTICULAR PURPOSE, AND NON-INFRINGEMENT.

We do not warrant that:

  • The App will be uninterrupted, error-free, or free of viruses or other harmful components.
  • Any defects will be corrected.
  • AI-generated content will be accurate, complete, or suitable for your needs.

Some jurisdictions do not allow the exclusion of implied warranties, so the above exclusions may not apply to you.

11. Limitation of Liability

TO THE MAXIMUM EXTENT PERMITTED BY APPLICABLE LAW, IN NO EVENT SHALL THE DEVELOPER BE LIABLE FOR ANY INDIRECT, INCIDENTAL, SPECIAL, CONSEQUENTIAL, OR PUNITIVE DAMAGES, OR DAMAGES FOR LOSS OF DATA, BUSINESS, OR PROFITS, ARISING OUT OF OR IN CONNECTION WITH THESE TERMS OR YOUR USE OF THE APP, EVEN IF THE DEVELOPER HAS BEEN ADVISED OF THE POSSIBILITY OF SUCH DAMAGES.

THE DEVELOPER'S TOTAL CUMULATIVE LIABILITY TO YOU FOR ANY CLAIMS ARISING OUT OF OR RELATED TO THESE TERMS OR THE APP SHALL NOT EXCEED THE AMOUNT YOU PAID FOR THE APP (INCLUDING ANY IN-APP PURCHASES) IN THE TWELVE (12) MONTHS PRECEDING THE CLAIM.

12. Indemnification

You agree to indemnify and hold harmless the Developer from any claims, damages, losses, or expenses (including reasonable attorneys' fees) arising from: (a) your use of the App in violation of these Terms; (b) Your Content; (c) your violation of any applicable law or third-party rights.

13. Third-Party Services

The App integrates with Apple platform services (App Store, iCloud, StoreKit, Apple Intelligence). Use of those services is governed by Apple's own terms and policies. We are not responsible for the availability or conduct of any third-party service.

14. Updates and Changes to the App

We may update the App from time to time to add features, fix bugs, or comply with legal requirements. Updates may modify or remove features, including free-tier functionality. We will endeavor to communicate material changes through App Store release notes.

15. Changes to These Terms

We may revise these Terms at any time. When we do, we will update the "Last Updated" date at the top of this document. Your continued use of the App after any update constitutes acceptance of the revised Terms. We encourage you to review these Terms periodically.

16. Termination

We reserve the right to suspend or discontinue the App at any time without notice. If you wish to stop using the App, simply uninstall it. Sections 7 through 15, and any other provisions that by their nature should survive, will survive termination.

17. Governing Law and Dispute Resolution

These Terms are governed by and construed in accordance with the laws of the State of North Carolina, United States, without regard to its conflict-of-law provisions.

Any dispute arising from these Terms or your use of the App shall first be addressed through good-faith negotiation. If unresolved, disputes shall be subject to binding arbitration under the rules of the American Arbitration Association (AAA), conducted in Winston Salem, North Carolina. Each party waives the right to a jury trial and to participate in any class action.

18. Apple-Specific Terms

As the App is distributed through the Apple App Store, the following additional terms apply:

  • These Terms are between you and the Developer only, not Apple.
  • Apple is not responsible for the App or its content.
  • Apple has no obligation to provide maintenance or support for the App.
  • In the event of any failure to conform to applicable warranty, you may notify Apple, and Apple will refund the purchase price (if any) to you. Apple has no other warranty obligation with respect to the App.
  • Apple is not responsible for addressing any claims relating to the App or your possession and use of the App, including (i) product liability claims; (ii) any claim that the App fails to conform to any applicable legal or regulatory requirement; and (iii) claims arising under consumer protection or similar legislation.
  • Apple and Apple's subsidiaries are third-party beneficiaries of these Terms, and upon your acceptance of these Terms, Apple will have the right (and will be deemed to have accepted the right) to enforce these Terms against you as a third-party beneficiary.
