Terms of Service
Last updated: 13 November 2026
These terms govern your use of the OtterPix Mac application and the otterpix.app website. By installing the app or visiting the site, you agree to them.
1. The service
OtterPix is a Mac image-processing application. Core tools — format conversion, compression, rotation, resize, crop, watermark, QR code, PDF conversion, batch pipeline, AI generation, AI text recognition (OCR) — are free. Five Pro AI features (AI Upscale, AI Cutout, AI Eraser, AI Anonymize, AI Face Restore) and Folder Automation, which watches a folder and applies a saved preset automatically, require an active OtterPix Pro entitlement obtained through the Apple App Store, either from a monthly or yearly subscription or from the lifetime in-app purchase.
2. License
Subject to your compliance with these terms and, for Pro features, an active Pro entitlement, we grant you a personal, non-exclusive, non-transferable, revocable license to install and use OtterPix on any Mac you own or control. You may not redistribute the app binary, reverse engineer it except as permitted by applicable law, or remove proprietary notices.
3. Pro purchases and billing (Apple App Store)
OtterPix Pro is offered through the Apple App Store as monthly and yearly auto-renewing subscriptions and as a lifetime non-consumable in-app purchase. Payment is charged to your Apple ID at purchase confirmation. Monthly and yearly subscriptions renew unless cancelled at least 24 hours before the end of the current period; manage or cancel them at System Settings → Apple ID → Subscriptions on Mac or at https://apps.apple.com/account/subscriptions. The lifetime purchase is charged once, does not renew, and is not a subscription to cancel. Eligible purchases can be restored with the same Apple ID. Apple handles refunds under its policy at https://reportaproblem.apple.com.
4. Your content
You own every image you load, process, or generate with OtterPix. The Mac app processes images entirely on your device; we never receive, see, or store them. You are solely responsible for ensuring you have the rights to use any input image or AI prompt, and for how you use the outputs.
5. AI-generated content
The AI models made available for use with OtterPix are third-party open-source models (Flux 2 Klein 4B under Apache 2.0, Real-ESRGAN, BiRefNet, LaMa, RF-DETR-Seg, RestoreFormer++, Unlimited-OCR). Their weights are downloaded on demand rather than bundled with the app. Generated outputs are not pre-filtered. You must not use the AI features to create content that is illegal, infringes third-party rights, depicts real individuals without consent, or violates Apple App Store guidelines. You bear sole responsibility for content you produce.
6. Regional availability
AI Image Generation and AI Text Recognition (OCR) are currently unavailable in the version of OtterPix distributed through the mainland-China Mac App Store. Image Generation is withheld for applicable local generative-AI compliance; OCR is withheld because of current model-delivery cost and operational constraints, not because OCR is classified as generative AI. All other features — including AI Upscale, AI Cutout, AI Eraser, AI Anonymize, AI Face Restore, and the image-processing toolset — remain available in every region we ship to. We may revise this availability as legal and delivery conditions change.
7. Acceptable use
Do not use OtterPix to process content you do not have rights to; to attempt to extract, redistribute, or fine-tune downloaded model weights outside their own licenses; or to interfere with the app or website (scraping, denial of service, security probing without authorization).
8. Third-party software and licenses
OtterPix uses open-source components, each governed by its own license, including Flux 2 Klein 4B (Apache 2.0), Real-ESRGAN, BiRefNet, LaMa, RF-DETR-Seg, RestoreFormer++ (Apache 2.0), Unlimited-OCR (MIT), MLX (Apple), libwebp (BSD), and libavif (BSD-2-Clause). Attribution and full license texts are available in the app's About screen.
9. Disclaimer of warranties
OtterPix is provided "AS IS" and "AS AVAILABLE", without warranties of any kind, express or implied, including but not limited to merchantability, fitness for a particular purpose, accuracy of AI output, or non-infringement.
10. Limitation of liability
To the maximum extent permitted by law, our aggregate liability for any claim arising from or related to OtterPix is limited to the greater of (a) the amount you paid for OtterPix Pro, whether subscription fees or the lifetime purchase price, or (b) USD 50. We are not liable for indirect, incidental, consequential, or punitive damages. Nothing here limits liability that cannot be limited under applicable law.
11. Termination
You may stop using OtterPix at any time and, where applicable, cancel a monthly or yearly subscription. A lifetime purchase is a one-time purchase, not a subscription to cancel. We may suspend or terminate access if you materially breach these terms. Sections that by their nature should survive termination — license restrictions, disclaimers, limitations of liability — will survive.
12. Changes to these terms
We will update the "last updated" date when these terms change. Material changes will be announced on this page at least 14 days before they take effect. Continued use after changes constitutes acceptance.
