Wizabee ("the App") is an iOS application, including its Apple Watch app, developed and provided by Kyosuke Tachibana ("we", "us"). This policy explains how information is handled in the App.
Regardless of where you live, the App never collects any of the following:
The App requests the following device permissions:
Sensor readings are processed on your device and are used only to match the music tempo to your steps, to make your walk records, and to count the distance for Honey.
Each time you walk, the App saves a record of the walk on your device. This record includes a summary of the walk (date and time, duration, steps, distance, walking tempo, and similar values), values such as your walking tempo every 10 seconds, the time of each step as your foot lands, and values such as your walking tempo and the song's speed about every second. The App also saves on your device your Honey and Setlist records (Section 17) and the order of the songs you added that you played most recently. These records stay only on your device, are for use within the App, and are not sent to us (what is sent in collaborator mode is described in Sections 2 and 14). The App installed from the App Store does not record the raw sensor readings (acceleration and rotation values taken 50 times per second).
The App also saves the following records only on your device. They are not shown on screen and are not sent to us (not even in collaborator mode). They are deleted when you delete the App (as described in the paragraph below, they may be included in your device backups).
The App reads these within the "Motion & Fitness" permission you have already given and does not ask for any new permission. If you have not given the permission, or your device lacks the feature, they are not recorded. The App does not keep your average or maximum heart rate (Section 16).
The records on your device are removed when you delete the App, except for the following:
Media library access is used only to show the list of songs and to copy the songs you pick into the App. Neither the list nor the songs are ever sent off your device.
In addition, wherever you live, the App connects to our sales server to check the song of the month. The App adds only a random one-time value to this connection — none of the information above and no user ID (for the IP address and other details that reach the server by the nature of network communication, see Section 15).
Only if you live in Japan and turn on collaborator mode as described in Section 14, the App sends the following information to our server. Collaborator mode is off by default, and the App works exactly the same whether or not you turn it on.
This section does not apply to users outside Japan. In those regions no consent prompt is shown and none of the information described in this section is sent. See Section 13.
Even when collaborator mode is on, your heart rate, values read from Health, and your Honey and Setlist records are never sent.
When such data is sent, our server's access log records the originating IP address. This is unavoidable in network communication and is used only to detect unauthorised access and to investigate faults.
We use this information solely to improve step detection and the accuracy with which music is matched to your walking pace.
We do not share or sell it to third parties, and we do not use it for advertising.
Information is stored on servers located in Japan (Supabase, Tokyo region).
Collected information is retained for one year in principle and deleted after that period.
Song purchases and Wizabee Plus subscriptions in the App are processed by Apple Inc. Payment information is handled by Apple Inc. and is never received by us. What we receive from Apple Inc. is aggregated sales figures only. The App checks your purchase status (which songs you bought and whether Wizabee Plus is active) on your device through Apple's systems and does not send it to us.
Honey (Section 17) is earned by walking and cannot be bought with money.
This section applies wherever you live. Please refer to Apple's privacy policy for how Apple Inc. handles your information.
You can stop the upload at any time by turning off collaborator mode (Section 14) under "Contribute" in the Settings tab. Once it is off, all sending described in Section 2 and Section 14 stops, and no further information described in Section 2 or Section 14 leaves your device (the song-of-the-month check in Section 15 continues, but no user ID or similar is added to it).
Stopping the upload does not delete information that was sent previously. To request deletion, please use the procedure in Section 7.
To request access to, or deletion of, stored information, please contact us at the address in Section 9, quoting the anonymous ID shown on the collaborator mode screen in Settings.
We will normally respond within one month.
Without the anonymous ID we cannot determine which stored records are yours, because we do not hold your name or any other contact details. In that case we are unable to act on the request.
The on-device records described in Sections 16 and 17 are not held by us, so they are not covered by access or deletion requests. See those sections for how to delete them.
Communication is encrypted. Access to stored data is restricted, and the App is configured so that one user's device cannot read another user's information.
The App is not directed at children. It should not be used by anyone under 16.
If we change the types of information we collect, we will ask for your consent again within the App.
Other changes take effect when published on this page.
We do not carry out automated decision-making that produces legal effects concerning you or similarly significantly affects you.
The walking-tempo detection, the playback-rate adjustment, and the slowing of the music when your heart rate stays above your limit (Section 16) are device-side features and do not make any determination about your rights, legal status, or health.
For users outside Japan, we do not collect personal data or usage data. However, during the song-of-the-month check in Section 15, and only then, your IP address and the information iOS adds to every request automatically (Section 15-2) briefly reach our server because of how network communication works. We do not store them, and we do not use them to identify anyone. How Cloudflare, whose network carries this connection, handles it is described in Section 15-4.
Specifically:
Outside Japan, the only communication the App has with our servers is the song-of-the-month check in Section 15. Your walk records, records of how you use the App, motion sensor readings, and heart rate are processed on your devices (including between your iPhone and your Apple Watch, if you use one) and are never sent to us. Purchases and subscriptions, and checks of their status, are handled between the App and Apple through Apple's systems (Section 5).
The data described in Sections 2 and 14 is sent to our server only when the App Store storefront country is Japan and the device's region setting is Japan. If either indicates a region other than Japan, this data is not transmitted. If the region cannot be determined, it is not transmitted either.
Because we do not collect personal data from users in the European Economic Area (EEA), the United Kingdom, or Switzerland as described above, we have not appointed a representative in the Union or in the United Kingdom.
For any data protection enquiry, please contact us at the address in Section 9.
As we hold no personal data relating to you, there is no data to which a request for access, rectification, erasure, restriction of processing, portability, or objection could apply.
If you contact us, we will confirm this to you. We will normally respond within one month, free of charge.
If you have concerns about how we handle your information, you have the right to lodge a complaint with the data protection supervisory authority in the country where you live or work. A list of national supervisory authorities in the EEA is published on the website of the European Data Protection Board (EDPB). In the United Kingdom, the supervisory authority is the Information Commissioner's Office (ICO).
As stated in Section 5, song purchases and Wizabee Plus subscriptions are processed by Apple Inc. For that processing, Apple Inc. acts as a controller independently of us.
If we ever change the App so that we do collect personal data outside Japan, we will revise this policy and put the necessary measures in place — including appointing a representative in the Union where required — before making that change.
The App includes a way for users to share records from actual use, to help us improve step detection and the accuracy with which music is matched to your steps. We call this collaborator mode.
You can turn on collaborator mode in the Settings tab. It is on only after you agree to the terms of this section. It is off by default. Turning on collaborator mode also turns on the sending of the information described in Section 2. The walking measurements in Section 2 (1) — the record of your walk — include the duration, step count, distance (approximate), and the date and time of the walk.
Until November 30, 2026 (Japan time), while collaborator mode is on, you can use all five included songs and choose up to six songs you added yourself (you choose which ones). When you turn it off, those choices are released, and just once, right afterwards, you can choose again within the limit that then applies. No song file is ever removed from your device. This is not a purchase, and there is no charge.
From December 1, 2026 (Japan time), the songs you can use do not depend on collaborator mode. If you had collaborator mode on before that date, you keep all the included songs and can keep up to six of your own songs in your Setlist (Section 17). This is not a purchase, and there is no charge. No song file is ever removed from your device.
From version 1.7, the App has no way to send a signal, and no new information described in this section is created. However, if records created by version 1.6 or earlier have not yet been sent and remain on your device, they may be sent from version 1.7 or later, but only while Collaborator Mode is on and your consent is in place, and only within 7 days of their creation (up to 5 records). Records are sent only if Collaborator Mode is on and you have given consent, and only after the App confirms that you are using it in Japan. Records older than 7 days are deleted from the device without being sent. If you turn off Collaborator Mode, they are not sent.
In version 1.6 or earlier, while collaborator mode is on, if the music feels wrong and you use your earphones to send a signal, the following information is sent to our server:
The comparison periods are sent because we need a baseline to judge whether the moment you signaled was different from normal.
Only while collaborator mode is on and you have agreed to the terms covering songs you add, the following is sent for each song you played, for walks in which you played songs you added yourself. If you have not agreed to those terms, nothing from that walk is sent at all, including the measurements described in Section 2.
This is sent so that we can investigate why music does not match your steps for songs you add. The title, the artist name, the file name, and the contents of the file itself are never sent.
While Collaborator Mode is on, the following app settings are sent together with the measurements described in Section 2, so that we can learn which settings are used and improve the screens.
They are not sent when Collaborator Mode is off.
The walking data you share as a collaborator includes how long you used each tempo mode (Normal, Half, Three-quarter) and how many times you switched. We use this to learn how the modes are used and to improve tempo matching. It does not include information that identifies you, such as your name.
Nothing is sent while Collaborator Mode is off.
You can turn off collaborator mode at any time in the Settings tab. Once it is off, nothing further is sent.
Turning it off does not delete information that was sent previously. To request deletion, please use the procedure in Section 7.
As in Section 4, this information is stored on servers located in Japan, retained for one year in principle, and deleted after that period.
As described in Section 13, collaborator mode is not available to users outside Japan. The collaborator mode item is not shown, and no collaborator mode data is sent.
The App reads, from our sales server (shop-api.wizabee.com), which song is the "song of the month" (it changes on the 1st of each month, Japan time) and the current time. This happens wherever you live and whether or not collaborator mode is on: when you open the App, when you return to it, and when the month changes.
The App sends only a random one-time value, newly created for each request. It is used only to check that the response is genuine, and it does not identify you.
Because of how network communication works, your IP address and the information iOS adds to every request automatically (the App's name and build number, values showing the versions of the iOS networking component and of iOS, and your language settings) also reach the server.
This connection does not send the anonymous ID, device model, walk records or collaborator mode records described in Section 2, purchase information, the titles or files of songs you added, your location, your name, or similar information.
Our sales server runs on Cloudflare, Inc.'s platform (Cloudflare Workers). It is configured not to store the content of these requests and not to keep per-request logs (access logs). We do not identify users or create records from this connection.
However, the connection passes through Cloudflare's network (including locations outside Japan). Cloudflare may keep aggregated statistics, such as the number of requests, and records of traffic it judges to be an attack, for a period under its own policies, to operate its service and protect against attacks.
Responses carry our signature, and the App uses only content whose signature it has verified. If the App cannot connect, walking works as usual.
This section applies wherever you live.
The Health and Apple Watch features work only when you turn them on in Settings under "Health and Apple Watch". They are off by default. When you turn one on, and when you press ▶ to start a walk with "Heart rate limit" on, your iPhone and your Apple Watch each ask for Health permission if you have not yet decided on any of the items. You can change the permission at any time in the Health app or in Settings. Walking works the same if you leave them off.
With "Save walks to Health" on, the App saves the duration and distance of each walk to Health as a walking workout. For walks where you measured your heart rate with Wizabee on Apple Watch, the watch saves the workout (including duration, distance, and heart rate), and the iPhone does not save the same walk a second time.
The watch, too, saves the workout only when "Save walks to Health" is on in the App on your iPhone (if the watch could not reach your iPhone during the walk, it follows the setting it last received from your iPhone, and saves nothing if it has never received one). Walks shorter than 60 seconds are not saved by either your iPhone or your Apple Watch, even when the setting is on.
When you turn on "Heart rate limit" and enter a limit, Wizabee on Apple Watch opens when you start walking and measures your heart rate. Your heart rate goes directly from your watch to your iPhone through Apple's workout system. If it stays above your limit, the App gradually slows the tempo of the music, and returns it when your heart rate comes down.
The limit is a number you choose as a guide. The App is not a medical device. It does not assess your health or give any diagnosis or treatment advice.
Your heart rate and the values read from Health are used only on your iPhone and Apple Watch and are never sent to our server, even when collaborator mode is on. We do not give them to third parties, use them for advertising, or sell them. We do not store them in iCloud.
This section applies wherever you live.
Honey builds up with the distance you walk while playing music in the App. Your Setlist is the set of your own songs you can play without Wizabee Plus. Songs you added that are not in your Setlist are kept in "Stock" and are not deleted. You can use Honey to change the songs in your Setlist. You earn 1 Honey for every 3 km you walk with music playing, and there is no limit to how much you can keep. Honey stays if you end Wizabee Plus. Without Wizabee Plus, the only use of Honey is to change the songs in your Setlist. Honey cannot be bought with money and cannot be exchanged for money. In the App installed from the App Store, Honey and the Setlist are available from December 1, 2026 (Japan time). Walks before then are not counted for Honey.
The distance for Honey is counted on your device, only for the parts of a walk where the pedometer distance, the App's step detection, and Apple's motion activity (walking or in a vehicle) agree, and music was playing. Location is not used.
Your amount of Honey, the distance counted for each day, which songs are in your Setlist (identified by a value made from the file's content, not by title), and the order of the songs you added that you played most recently are stored only on your device and are never sent to us, even when collaborator mode is on.
Because these records exist only on your device, they move to a new iPhone only when you restore it from an encrypted backup (including iCloud Backup). They are not synced through iCloud Keychain. We do not hold these records, so we cannot restore them for you.
