App — On-Device Processing

MiaoSense processes all data — including camera footage, microphone audio, and behavioural scores — locally on your Android device. No video, audio, or analysis data is ever sent to our servers or any third party. The app operates fully offline and does not use any third-party crash-reporting or analytics SDKs. A small set of first-party technical usage events is recorded locally, as described below.

Data stored locally on your device:

• Cat profiles you create (name, breed, age, notes)
• Analysis session results
• Your consent record (timestamp, Terms version, app version, locale)
• App preferences (theme, language, sensor settings)
• Local usage events (which app functions you use, timestamps, session number, app version)

MiaoSense reads your device's system language setting (locale) to display content in the appropriate language. This information is processed locally and, if you change the in-app language, stored on your device only.

You can export or permanently delete all locally stored data at any time via Settings → Data → Delete all data.

Legal basis: Art. 6(1)(b) GDPR — processing necessary to provide the App's functionality.

AI Processing

MiaoSense analyses camera images and — if you use the vocalisation feature — microphone audio using artificial intelligence models that run entirely on your device. The models detect your cat, describe visible movement and posture patterns, and derive behavioural indicators from them.

These results are probability-based estimates. They are not confirmed findings and not a veterinary diagnosis, and no person reviews them before they are shown to you. Lighting, camera angle, or an unusual posture can affect how reliable an estimate is.

The models are not adapted using your recordings. Nothing you record is used to train or improve them, and no recording, audio file, or analysis result is transmitted to us or to any third party — neither for that purpose nor for any other.

People who appear in a recording: MiaoSense looks for cats. It does not run face recognition, does not identify people, and does not analyse the behaviour or emotional state of anyone who happens to be in the frame. If a person is visible in your footage, that footage is still processed only on your device and is never transmitted.

Because every analysis runs on your device and no result is transmitted, there is no automated decision-making within the meaning of Art. 22 GDPR: MiaoSense produces information for you, and no legal effect or similarly significant consequence follows from it.

Legal basis: Art. 6(1)(b) GDPR — processing necessary to provide the App's functionality.

MiaoWatch — Remote Camera

The optional MiaoWatch feature lets you connect MiaoSense to a camera stream (e.g. an IP camera or webcam) via a URL you enter manually. When MiaoWatch is active:

• The App establishes a network connection exclusively to the URL you configured.
• Video frames are processed in RAM on your device and are never stored or forwarded to MiaoSense servers or any third party.
• The camera URL you enter is stored locally on your device only.
• No data from the camera stream leaves your device.

You are responsible for ensuring you have the legal right to access and monitor the camera you connect to. MiaoSense does not verify the source or legality of the stream.

Storage period: The camera URL remains stored on your device until you remove it manually (Settings → MiaoWatch → Remove Camera) or uninstall the App. Video frames are processed in RAM during active streaming only and are never stored. There are no recipients of your camera data — all processing is on-device; no data is transmitted to MiaoSense or any third party.

Legal basis: Art. 6(1)(b) GDPR. By activating MiaoWatch, you enter into a service arrangement for this optional feature. Processing your camera URL is objectively necessary to establish the connection you requested — without it, MiaoWatch cannot function.

Local Usage Statistics

The App records a small number of technical usage events on your device — for example when a feature is switched on, when a purchase is confirmed, or whether the on-device AI models loaded successfully. This helps us improve the App and diagnose faults.

• Categories: event name, timestamp, in-app session number, app version, technical attributes.
• Storage: exclusively on your device. These events are never transmitted — there is no network path for them, and no analytics SDK is involved.
• Recipients: none. No third-country transfer occurs, as this data never leaves your device.
• Storage period: until you delete it (Settings → Data → Delete all data) or uninstall the App. Events are not automatically capped or rotated.

Legal basis: Art. 6(1)(f) GDPR — our legitimate interest in a stable, improvable App. Because these events never leave your device and contain no content of your recordings, the balancing of interests weighs in favour of processing. You may object to this processing at any time (Art. 21 GDPR): turn off Settings → Data → Local usage statistics and nothing further is recorded. Events already recorded can be removed via Settings → Data → Delete all data.

Website — Hosting & Infrastructure

miaosense.app is hosted on Cloudflare Pages (Cloudflare, Inc., USA). As part of its content delivery and security services, Cloudflare processes standard request metadata (IP address, user agent, timestamp) on its servers. No cookies are set by this website and no analytics tools are installed.

Cloudflare is certified under the EU–US Data Privacy Framework (DPF), an adequacy decision pursuant to Art. 45 GDPR, which permits data transfers to certified US recipients without additional safeguards.

The DM Sans typeface is served locally from our own server (self-hosted). Loading the font does not establish any connection to Google or other third parties, and no data is transmitted to third parties in the process.

Legal basis: Art. 6(1)(f) GDPR — our legitimate interest in operating a secure, reliable website.

User-Exported Media

MiaoSense allows you to save analysis photos and vocal recordings ("exported media") on your device. Exported media is stored exclusively on your device and is not transmitted to Purrception or any third party.

Exported media may contain a visible disclaimer label burned into the image ("MiaoSense — not a vet substitute") and, where applicable, a low-confidence indicator. These labels are for informational purposes and remain part of the file.

Sharing exported media is an action you take in your own responsibility. When you share files via third-party apps (WhatsApp, Instagram, email, etc.), those apps' own privacy policies apply. Please ensure that no identifiable persons are visible in any media you choose to share (see § 201a of the German Criminal Code (StGB) and equivalent national criminal-law provisions in other EU jurisdictions).

Saved media files can be deleted at any time through your device's gallery app or file manager.

Legal basis: Art. 6(1)(b) GDPR — processing necessary to provide the requested export functionality.

Email Contact

If you contact us at hello@miaosense.app, we process your email address and the content of your message solely to handle your enquiry. We do not share this information with third parties. Correspondence is retained only as long as necessary to resolve your enquiry and is then deleted.

Providing your email address is voluntary. If you choose not to, we are unable to respond to your enquiry.
