Terms of Service & Disclaimer

1 Introduction

These Terms of Service ("Terms") govern your use of the MiaoSense mobile application ("App") and the website miaosense.app. MiaoSense is developed and operated by Purrception, operated by Robert Sommer, Isoldenstrasse 26, 80804 Munich, Germany ("we", "us", or "Purrception").

By installing, accessing, or using the App, you confirm that you have read, understood, and agreed to be bound by these Terms. If you do not agree, you must not use the App.

2 Acceptance of Terms

MiaoSense presents these Terms during its first launch in an onboarding screen that requires your explicit confirmation via a checkbox before the App becomes functional. This constitutes your legally binding acceptance of these Terms.

A consent record — including the timestamp, Terms version, app version, and your device locale — is stored locally on your device in accordance with Art. 7(1) GDPR.

You must be at least 16 years old to use MiaoSense. By accepting these Terms, you confirm you meet this age requirement.

3 Description of the App

MiaoSense is an on-device AI application for Android that uses your device's camera and microphone to observe your cat's posture, body language, and vocalisations. The App generates behavioural indicators and Feline Grimace Scale (FGS) scores to help you understand patterns associated with your cat's wellbeing.

Key characteristics of the App:

• On-device processing only — all AI inference runs locally on your device; no data is sent to external servers
• No data transmission — no video, audio, or behavioural data is ever transmitted to Purrception or third parties
• Offline operation by default — no internet connection is required for core analysis; the optional MiaoWatch remote camera feature requires a network connection to the camera
• Privacy-first design — your cat's data never leaves your device
• Observational only — all outputs describe patterns observed; MiaoSense does not provide recommendations or advice on how to act

MiaoSense may in future offer optional paid features (in-app purchases). Any such features will be clearly labelled, and separate consent or purchase steps will apply.

4 Disclaimer: AI Outputs

MiaoSense uses artificial intelligence models to observe and assess your cat's behaviour and wellbeing. The analyses, scores, and indicators the App provides are AI-generated estimates for informational purposes only.

AI-based assessments are inherently probabilistic and may be inaccurate. Factors that can affect reliability include:

• Lighting conditions and contrast
• Camera distance and angle
• Unusual or obscured body postures
• Background noise or ambient sound
• Device camera and microphone quality

Outputs may vary between sessions even under identical conditions, as AI models produce probabilistic results. The App's assessments do not constitute a medical, scientific, or veterinary opinion.

5 Not a Substitute for Veterinary Advice

Always consult a licensed veterinarian for any health concerns about your cat. Do not delay or withhold veterinary care based on the App's outputs. If your cat shows signs of distress, injury, or illness, seek professional veterinary attention immediately.

MiaoSense is not a medical device and has not been evaluated or approved by any regulatory authority for veterinary or medical use. It is a consumer information tool only.

6 Limitation of Liability

To the fullest extent permitted by applicable law, Purrception (Robert Sommer) shall not be liable for any direct, indirect, incidental, consequential, or special damage, harm, or loss arising from or in connection with:

• the use or inability to use the App;
• reliance on AI outputs, scores, or indicators provided by the App;
• delays in or decisions against seeking veterinary treatment based on App readings;
• misinterpretation of behavioural indicators;
• technical errors, interruptions, or inaccuracies in AI analysis.

Nothing in these Terms excludes or limits our liability for:

• death or personal injury caused by our wilful misconduct or gross negligence;
• fraud or fraudulent misrepresentation;
• liability under the German Product Liability Act (Produkthaftungsgesetz — ProdHaftG), including the version applicable from 09 December 2026 (Directive 2024/2853);
• any other liability that cannot be excluded or limited under applicable mandatory law.

Where liability cannot be entirely excluded, it is limited to foreseeable, typical damage at the time of contracting.

7 AI Transparency — EU AI Act Art. 50

MiaoSense uses an AI system within the meaning of Regulation (EU) 2024/1689 (EU AI Act). Pursuant to the transparency obligation under Article 50 of the EU AI Act, we hereby inform you that:

• The App employs machine learning models (computer vision and audio classification) to generate behavioural assessments of cats.
• All AI processing occurs locally on your device (on-device processing); no data is transmitted to AI providers or external servers.
• The AI outputs are probabilistic estimates, not factual determinations.
• There is no automated decision-making with legal effect on any person (Art. 22 GDPR does not apply).

MiaoSense is classified as a limited-risk AI system subject to the transparency obligation under Article 50. The App analyses feline facial expressions and behaviour — not human emotions or biometric data — and does not fall within the high-risk AI system categories listed in Annex III of the EU AI Act. This classification will be re-evaluated upon any material expansion of features.

AI models used: YOLOv8 (cat detection), CatPoseAnalyzer, EfficientNet-B0 (emotion classification), CatFacsAnalyzer, VocalizationAnalyzer. All models run on-device via ONNX/TFLite runtime.

8 Privacy & On-Device Processing

MiaoSense is designed with privacy as a core principle. All analysis — including camera processing, audio analysis, and behavioural scoring — runs exclusively on your local device. No personal data, cat data, video, or audio is transmitted to Purrception or any third party.

Data stored locally on your device includes:

• Cat profiles (name, breed, age, notes) you create within the App
• Analysis session results and FGS score history
• Your consent record (timestamp, Terms version, app version, device locale)
• App preferences (theme, language, sensor settings)

You can export or permanently delete all locally stored data at any time via the App's Settings screen, in exercise of your rights under Art. 17 (right to erasure) and Art. 20 (right to data portability) GDPR. Full information on your data subject rights (Articles 15–22 GDPR) is available in the Privacy Policy.

As all processing is on-device, no international transfer of personal data within the meaning of Chapter V GDPR occurs in the ordinary course of App operation.

For full details, see our Privacy Policy.

8a User-Generated Analysis Media

The App allows you to create and save analysis photos and vocal recordings ("analysis media") on your device. The following terms apply specifically to your use of this feature.

8a.1 Disclaimer Label

All exported analysis media include a visible disclaimer label ("MiaoSense — not a vet substitute") burned into the file. This label may not be cropped or obscured in a way that misleads recipients about the informational nature of the content.

8a.2 Sharing Responsibility

When you share analysis media with third parties, you bear full responsibility for complying with applicable data protection law and criminal law, including:

• § 201a StGB (Germany) — unauthorised recording or sharing of images of persons in private spaces may be a criminal offence punishable by up to two years' imprisonment. In Austria: § 120 StGB; in Switzerland: Art. 179quater StGB. In other EU jurisdictions equivalent national criminal-law provisions apply.
• General data protection obligations under the GDPR where third parties are identifiable in shared recordings.

Before sharing any analysis media, you must ensure that no identifiable persons are visible in the recording. Purrception is not liable for any damages arising from your sharing of analysis media with third parties.

8a.3 On-Device Storage

Analysis media are stored exclusively on your device. Purrception does not receive, process, or access any exported media files. You can delete saved media at any time through your device's gallery app or file manager.

13 MiaoWatch — Remote Camera Feature

MiaoWatch is an optional feature that allows you to connect MiaoSense to a remote camera stream (e.g. an IP camera or webcam) via a URL you provide. The following terms apply specifically to your use of this feature.

13.1 Authorisation and Responsibility

By activating MiaoWatch and entering a camera URL, you confirm that you are legally authorised to access and monitor the camera stream you connect to — whether as the owner or as a person who has received explicit, documented permission from the owner and from all persons who may be captured by the camera. You must not use MiaoWatch to access cameras without such authorisation. Any unlawful use of MiaoWatch is exclusively your legal responsibility; Purrception accepts no liability for damages arising from your unlawful or unauthorised use of the feature.

13.2 Limitation of Liability

To the fullest extent permitted by applicable law, Purrception accepts no liability for:

• the availability, continuity, or quality of any camera stream you connect to;
• the content of such streams;
• any legal consequences arising from your use of MiaoWatch, including claims under data protection, privacy, or criminal law brought by third parties whose image may be captured;
• any data protection violations for which you, as the person operating the stream, are the responsible party under applicable data protection law.

This limitation does not apply to damages caused by Purrception's wilful misconduct or gross negligence, nor to liability for injury to life, body, or health. The general limitation of liability in §6 applies in addition to this clause.

13.3 Supported Protocols

MiaoWatch currently supports MJPEG-over-HTTP streams only. RTSP support is planned for a future release. Unsupported protocols or misconfigured URLs may result in a failed connection; no data is transmitted in such cases.
