SewLens Terms of Use

Effective date: November 10, 2026 · Last updated: November 10, 2026

App: SewLens ("SewLens: Sewing Pattern Maker") · Developer: Brock Hall (OrehRuoy)

The short version: SewLens drafts patterns as made-to-measure estimates, and we can't guarantee how they will fit. Purchases go through Apple or Google, and their refund policies apply. The app is provided as is. Patterns are built on FreeSewing, which is open source under the MIT License.

1. Agreement

These terms are between you and Brock Hall, the independent developer who publishes SewLens as OrehRuoy ("we" or "us"). By downloading or using SewLens, you agree to them. If you do not agree, please do not use the app.

2. License to use the app

We give you a personal, non-exclusive, non-transferable, revocable license to use SewLens on devices you own or control. Your use is also subject to the terms of the store you got it from: Apple's Media Services Terms and Conditions on iPhone and iPad, or the Google Play Terms of Service on Android. You may print and use the patterns you create for your own sewing.

3. Patterns are estimates, not a fit guarantee

SewLens drafts patterns from the measurements you enter and the design it suggests from your photo. Patterns are made-to-measure estimates. Fit depends on accurate measurements, correct printing at 100% scale, your fabric, and how the garment is sewn, so we do not guarantee that any pattern will fit or that a design suggestion will match the garment in your photo. Please check the printed test square, sew a test garment (muslin) before cutting your good fabric, and adjust as needed. We are not responsible for fabric, materials, or time spent on a project.

4. Purchases

• SewLens offers a one-time purchase and per-pattern purchases inside the app. What each purchase includes and its price are shown in the app before you buy.
• Apple processes payments on iPhone and iPad, and Google Play processes payments on Android. We never see your payment details.
• Refunds are handled by Apple or Google Play under their own refund policies. Please request a refund through the store you bought from.
• Purchases apply only to SewLens and do not carry over between the App Store and Google Play. Use Restore Purchases in the app to get a purchase back on a new device signed in to the same store account.

5. Acceptable use

You agree not to:

• Reverse engineer, decompile, or modify the app, except where the law allows it
• Try to bypass purchase or unlock checks
• Upload photos you don't have the right to use, or use the app for anything unlawful
• Resell or redistribute the app itself

6. Open-source credit: FreeSewing

SewLens patterns are drafted with FreeSewing, an open-source sewing pattern project. FreeSewing is used under the MIT License, reproduced below. FreeSewing is not affiliated with SewLens and does not endorse it.

The above copyright notice and this permission notice shall be included in all

7. No warranty

SewLens is provided "as is" and "as available," without warranties of any kind, express or implied. That includes warranties of merchantability, fitness for a particular purpose, and non-infringement. We do not promise the app will be error-free, always available, or work on every device. Design suggestions and pattern drafting need an internet connection.

8. Limitation of liability

To the fullest extent the law allows, we are not liable for any indirect, incidental, special, consequential, or punitive damages that arise from using or being unable to use SewLens, including the cost of fabric or materials. Our total liability for any claim is limited to the amount you paid for SewLens in the 12 months before the claim. Some places do not allow these limits, so they may not fully apply to you.

9. Changes to the app and these terms

We may update the app or change these terms. When the terms change, the date at the top of this page changes too. If you keep using SewLens after a change, you accept the updated terms.

10. Governing law

These terms are governed by the laws of the United States and the state where the developer lives, without regard to conflict-of-law rules. This does not take away any consumer protections you have under the laws where you live.
