In short: Wayo keeps complete routes, photo content, raw Health data, note text, and saved voice-note audio on your device by default. Individual coordinates may be handled by Apple’s system geocoding service to return place names. After you consent, Wayo sends device-linked usage and diagnostic data to improve the product. Product events may include city-level place names, dates, step and route summaries, and internal identifiers for journeys, posters, pages, and photos, but not the photos themselves, detailed addresses, or complete GPS point sequences. Only when you choose to send a trip to family or friends are that trip’s compressed photos, locations, route, and notes uploaded, and they are deleted automatically after 30 days (see section 5).
This policy explains how Wayo (the “App”) collects, uses, stores, and protects personal information, and the rights available to you. Please read it before using the App. By tapping “Agree and Continue,” you confirm that you have read and accepted this policy.
1. Information we collect and why
Wayo follows a data-minimization principle. The permissions below are requested only when you use a feature that needs them; they are not all requested when you first open the App.
Information
Purpose
Uploaded?
Location (GPS)
Record a journey route and obtain readable place names
The route stays on device by default; individual coordinates may be sent to Apple’s system geocoding service. When you choose to send a trip, that trip’s route and photo locations are uploaded, as described in section 5
Photos and photo library
Use capture time and location to help recover past outings and create memories; save trip photos that family and friends send you to your library
Photo content stays on device by default; a photo coordinate may be used with Apple’s geocoding service. When you choose to send a trip, that trip’s compressed photos are uploaded, as described in section 5
Faces in your photo library (Kids Growing Up)
After you create a child’s card, recognize the faces in your photo library on your phone to find that child’s photos
No. Recognition happens entirely on your phone, and the face data stays on your device; it is deleted with the last child’s card
Health data (steps, distance, heart rate, active energy, and workouts)
Show activity totals in the App and save a completed walk to Apple Health
Raw Health records stay on device. Aggregates for the previous 30 / 90 days are uploaded, and a product event related to viewing a day or journey may include the step summary for that day or journey, as described below
Motion and fitness activity
Distinguish walking, running, and vehicle travel to improve route accuracy
No; stored on device
Camera
Take photos during a journey
No; photos are handled as described above
Microphone, speech transcription, and voice-note audio
Turn speech into note text on supported devices and let you replay the original audio
Transcription and saved audio stay on device; Wayo does not use online speech-recognition fallback
Device and usage analytics
Understand feature use, crashes, and performance so we can improve the App (through the Umeng SDK and our own analytics service)
Yes; encrypted in transit and associated with a pseudonymous device identifier
“Stored on device” means that the relevant content is not sent to Wayo’s servers. Apple system services such as geocoding or iCloud are governed by your Apple settings and Apple’s terms; we do not gain access to your route or photo content through them.
2. Location information
We treat precise location and route history as sensitive personal information and apply heightened care. Location is essential to recording a route. We use it when you actively start a journey. To continue recording while the screen is locked or the App is in the background, Wayo may request “While Using the App” and background location access. Route history stays on your device and is not used for advertising; a trip’s route is uploaded only when you choose to send that trip (see section 5). To show a readable place name, Wayo may ask Apple’s system geocoding service to process an individual route or photo coordinate; Apple handles that request under its own privacy policy. You can disable location access at any time in Settings → Privacy & Security → Location Services.
3. Third-party SDKs and sharing
Wayo includes the Umeng+ U-App analytics SDK to understand product use and improve the App. We do not sell, rent, or proactively share your personal information with other third parties.
Information collected: device identifiers such as IDFV, device model, operating-system version, network and carrier information, crash and performance data, and usage events linked to a pseudonymous device identifier. Wayo does not request IDFA and does not track you across apps.
Purpose: measure App use, stability, and performance so we can improve the product
Processing: the SDK is initialized only after you consent to this policy; transmitted data is encrypted in transit
Information collected: IDFV, device model, operating-system version, App version, network status, time zone, and key in-App events such as opening the App, entering a city or journey, editing or saving a poster, or opening the memory grid. To understand whether these features work well, an event may include a city-level place name, calendar date, step count, distance, whether a route exists, route-point count, and internal App identifiers for a journey, poster, page, or photo. This does not include the photos themselves, detailed addresses, complete GPS point sequences, note text, voice-note audio, or other raw Health data.
Aggregate daily-step statistics: if you enable Health access, we send the median daily steps, days meeting 8,000 steps, and days with readable data for the previous 30 and 90 days. These windows exclude today and the periodic aggregate report does not contain a list of daily totals. As disclosed above, however, a product event triggered when you view a day, journey, or memory-grid item may include the step summary for that day or journey.
Photo recognition counts: if you allow Wayo to access your photo library, we send two numbers at most once a day per device: how many photos and videos Wayo has analyzed, and how many of them were recognized as showing a child. The analyzed items are only those Wayo looked at while choosing trip covers and highlights, not your whole library. Recognition happens entirely on your device; we do not upload photos or videos, or information about which ones they are.
Purpose: understand feature use and conversion, diagnose crashes and performance issues, and improve the product.
Transfer and storage: collected only after consent, encrypted in transit, and processed by our analytics infrastructure (tripbwh.duoduoipo.com). Its public service endpoint may be outside your country or region, so this processing may involve an international transfer. We use it only for product analytics, diagnostics, and security.
4. When you send feedback
The feedback feature uses a device identifier to check automatically for a developer reply. We receive your message, App and operating-system details, or diagnostic content only when you choose to submit them; diagnostic logs are not uploaded automatically in the background. Our support infrastructure may process these requests outside your country or region.
5. When you send a trip
You can tap “Send” on a trip’s card to share that trip with family and friends. The following is uploaded only after you tap Send:
What is uploaded: the trip’s title, date and time range, place names, steps, distance, and duration; the trip poster images; compressed photos (about 2048 pixels on the long edge, keeping capture time and location); the route; and note text. Original photos, voice-note audio, and raw Health records are not uploaded, nor is anything outside that trip. Photos that others sent you are not sent again.
Who can see it: anyone with the link can view the trip’s header card and posters on the web. People who have Wayo can add the photos and route to their own trips, and the photos are also saved to their photo library. Please send it only to people you trust.
How long it is kept: uploaded content is kept for 30 days and then deleted automatically. You can also tap “Delete Link” in the App at any time; the link stops working right away and uploaded content is deleted. Content that recipients have already added to their own devices is managed by them and is not affected.
Where it is stored: photos are stored in Baidu AI Cloud Object Storage (Beijing) and delivered through a CDN. The cover image displayed on the web (the poster generated for this trip), link information, and send records are stored on our servers in Beijing (apiwayo.sleepisland.cn and sleepisland.cn). Send records include a device identifier, which is used only for troubleshooting.
Reporting: inappropriate content can only be reported in the App; we remove it after review.
6. Storage and security
Your routes, photo content, Health data, note text, and voice-note audio are stored on your device. Deleting the relevant journey removes its saved note audio; removing the App removes all locally stored App data.
Trip content you choose to send is kept for 30 days as described in section 5, or deleted earlier when you close the link.
Analytics sent to Umeng is encrypted in transit and stored and processed in mainland China under Umeng’s policy.
Analytics sent to our service is encrypted in transit and used only for product analysis, diagnostics, and security. Its hosting may involve processing outside your country or region.
We use reasonable technical and organizational safeguards, but no internet-connected system can be guaranteed completely secure.
7. Your choices and rights
Access and manage: routes and photos stored by Wayo are visible and removable in the App.
Withdraw permission: you can disable location, Photos, Health, or another permission at any time in system Settings. The related feature may stop working, but previously recorded local data is not affected.
Delete data: delete an individual journey in the App, or remove the App to clear all locally stored App data.
Close a sent link: on a trip you have sent, tap “Send” → “Close Link”; uploaded photos are deleted right away.
Stop analytics: contact us using the email below if you want analytics collection to stop.
8. Children
Wayo is primarily intended for adults. If you are under 14, please review this policy with a parent or guardian and use the App only with their consent. We do not intentionally collect children’s personal information. If we learn that we have done so, we will delete it as soon as reasonably possible.
9. Changes to this policy
We may update this policy from time to time. If a material change occurs, we will request your consent again in the App. Please review the “Updated” date above.
