Michika — Privacy Policy
1. Overview
This policy explains what the Michika service collects, why, and what your choices are. Michika is operated by Jen Hao Yeh, an individual established in Taiwan (R.O.C.), who is the data controller for the purposes of this policy; contact support@michika.app. A postal address for formal notices is available on request; we answer within 30 days.
The short version: we collect what the product needs to work and to be run well — your Apple sign-in identifier, the places you ask to navigate to, a limited history of your drives, and information about how you use the app. We do not sell your data, there are no ads inside the app, and we do not track you across other companies' apps and websites — the app never asks for permission to track and never reads your device's advertising identifier.
2. What we collect and why
| Data | Details | Why |
|---|---|---|
| Account | Your Sign in with Apple identifier and, if you choose to share it, your email address (which may be an Apple private-relay address). We do not send marketing email. | Creating and securing your account, and answering you if you write to us. |
| Location and navigation | Location information your device sends when you plan a route, search for a place or use a location-aware feature, and the destinations you choose. Your recent destinations are kept on your phone. | Providing navigation, search and guidance. |
| Route and search history | For routes and searches handled by our servers: an approximate start and end point, the route, its distance and estimated time, when it was requested, and what you searched for. | Diagnosing navigation problems, improving the Service, and helping you when you contact support. |
| Usage and drive activity | When and how long you use the app, on which screen, app and system versions, navigation events during a drive (for example that a route started, rerouted or arrived), the approximate city and country where a drive started, and counts of the features you use. | Understanding how the Service is used, keeping it reliable, enforcing plan limits, and supporting you. |
| Guidance content | The text of the guidance and phrases the app delivers to you, which can include a road or place name, with its language and the character voice used. It does not include your coordinates or any recording of you. | Checking quality and fixing faults. |
| Product feedback | If you send feedback in the app: your message, any images you attach (with their metadata removed), the category and the time. Only authorized Michika operators can read it. | Reviewing suggestions, bug and subscription reports, and inquiries. |
| Conversations | Conversation features are not currently available. If they are enabled in a future version, the messages exchanged will be processed to provide them, and this policy will be updated first. They will not be used to train general-purpose AI models. | Providing the conversation. |
| Subscription state | Purchase and renewal information from Apple (product, dates, and a reference linking the purchase to your account). Never your card details. | Activating and managing the plan you paid for. |
| Device and security information | Technical identifiers needed to protect licensed content on your device, and the request logs our hosting provider keeps (including IP address). | Security, abuse prevention, protecting licensed content and fixing faults. |
The microphone is not used in the current version, and the app does not ask for it. These records can be viewed, per account, by the operator to run the Service and to answer you when you write to us. They are not shared with anyone for their own purposes, not used for advertising, and not combined with data from other apps or companies.
3. Who processes it
We use service providers that process data on our behalf, each receiving only what its function needs and bound to protect it:
- Apple — sign-in, billing, and Apple Maps features.
- Cloud hosting and infrastructure providers — hosting, storage and the computing that delivers the Service's features.
- Mapping providers — receive what is needed to compute routes and answer searches.
- AI service providers — only if conversation features are enabled in a future version, to provide them.
- Meta Platforms — Meta's app-events kit tells Meta that the app was installed and opened and about App Store purchases, with basic device and app information and your IP address, so we can measure our own ads on Facebook and Instagram. It does not receive your name, email, sign-in identifier, location, routes or searches, and no advertising identifier. See Meta's privacy policy.
Data may be processed outside your country, including in Japan, Taiwan and the United States. We do not sell your data or share it with data brokers.
4. Retention and deletion
- We keep personal data for as long as your account is active and as long as needed for the purposes described in this policy — providing, maintaining and improving the Service, security, and meeting legal obligations, resolving disputes and enforcing our agreements. When it is no longer needed, we delete it or make it anonymous.
- Deleting your account in the app (iPhone: Account ▸ Delete account; also on the CarPlay screen) removes your personal data from our systems immediately; residual backup copies expire within 30 days.
- Revoking Sign in with Apple signs you out and blocks access but does not delete your account. To delete, sign in again and use Delete account, or email us. If Apple tells us your Apple Account has been deleted, we delete your Michika data too.
- So that a free trial cannot be repeated, we keep, after deletion, only the opaque sign-in identifier Apple gives us and your trial usage. Nothing else about you remains.
- Aggregate, non-identifying statistics may be retained.
5. Security
Data is encrypted in transit and at rest, and access is limited to the operator. Payment card data never touches our systems.
6. Children
Michika is intended for people aged 13 or over (or the minimum age of digital consent where you live), as set in our Terms. We do not knowingly collect data from children under 13; if you believe a child has used the Service, contact us and we will delete the data.
7. Your rights
Depending on where you live, you may have rights to access, correct, export or delete your personal data, and to complain to a supervisory authority. Deletion is self-service in the app. For anything else, contact support@michika.app — we will respond within 30 days. We will post the current policy here and note material changes in the app.
