Privacy Policy — KnotBots.ai

1. Overview

KnotBots.ai is operated by KnotTheory.ai Inc. ("we", "us", "our"). We build privacy-first applications, including Tess-Hoshi, Swapétit, and Tesseract-Prime. This policy explains what data these products collect, use, and share. Our tax products (Tesseract-Tax and Tesseract Tax Cloud) are covered by the policy at knottheory.ai/privacy.

2. Our Principles

Local-first. Wherever possible, your data is processed on your own device. Many features — including on-device AI models — work entirely offline.
No selling of data. We never sell, rent, or trade personal data.
No advertising and no tracking. Our apps contain no ads and no third-party analytics or tracking SDKs.
Minimal collection. When a feature needs the network, we transmit only what is required to fulfill your request, and we don't keep it afterward.

3. Cloud AI Processing (Optional Features)

Some apps offer optional cloud-powered AI features (for example, Swapétit's cloud answers, photo questions, recipe invention, and spoken answers). These features are off until you explicitly enable them. When enabled:

Only the content needed to answer — your question text and, if you attach one, your photo — is transmitted to our servers.
Requests are processed through AI infrastructure configured for zero data retention: your content is not stored, not logged, and not used to train models.
Generated speech audio is produced on transient compute and is not retained after delivery.
Some apps also let you supply your own API key for a third-party AI provider (such as Anthropic or OpenAI); in that case your content is sent directly to that provider under its own privacy terms.

4. Product Specifics

Tess-Hoshi

Recordings and transcripts stay on your iPhone. Speech recognition runs entirely on-device using Apple's native frameworks.
If you configure an upload destination, audio is sent only to the server you specify, under your control.
No accounts, no analytics, no data collection.

Swapétit

No account or sign-in. The kitchen converter and offline substitution library never touch the network.
On-device AI answers run entirely on your device. Cloud answers follow Section 3 and require your one-time consent.
Microphone audio for dictation is processed by Apple's on-device/system speech recognition; we do not receive or store your recordings.

Tesseract-Prime

All processing is performed locally on your device using on-device AI models. No data is sent to external servers.

5. Purchases & Subscriptions

In-app purchases and subscriptions (such as Swapétit Pro and Tess-Hoshi Pro) are processed by Apple. We do not receive or store your payment details.

6. Data Sharing

We do not sell, share, or transfer personal data to third parties, except for the processors described above (Apple and our cloud infrastructure providers) acting on our instructions to deliver the service you requested.

7. Data Retention

Cloud AI request content is not retained (Section 3). Your app content lives on your own device and is never held by us.

8. Your Rights

Depending on where you live (for example, under GDPR or the CCPA), you may have rights to access, correct, or delete personal data we hold. Because our apps hold your data on your own device, deletion is usually as simple as deleting the app; for anything else, contact us and we will help.

9. Children's Privacy

Our apps are not directed at children under 13. We do not knowingly collect any personal information from children. (Swapétit's "for kids" recipe option only tailors recipe suggestions — it collects nothing about any child.)

10. Changes to This Policy

We may update this privacy policy from time to time. Changes will be posted on this page with an updated revision date.
