DayPieces privacy policy
Effective: October 30, 2026 · App: DayPieces (com.mindstartium.daypieces)
1. Overview
DayPieces (the "app") lets parents plan their child's schedule and share it with family. There is no sign-up or account, and the developer runs no server that receives or stores your data. The app contains no analytics, advertising or crash-reporting tools.
App data is stored on the device and leaves it only when a parent turns on a feature described in sections 5 to 7, and only to the place the parent chooses.
2. Data stored only on the device
- Child: name, birth month, color, autonomy level
- Schedule: seasons (term, holidays), events, repeat rules, skipped days, one-day changes, notes
- Care: names of caring adults, place names, travel times, place locations picked on the map (optional), home location (optional)
- Kid mode records: child plans, done checks, looking back, stamps, pieces and coupons, routine, focus timer and time-guess records
- Class fees: fee rules, payments and expenses (amount, date, method, note)
- Settings: reminders, themes, parent PIN, family key
This data stays in the app's storage on the device and is not sent to the developer. The home location is not included in family files either. Uninstalling the app or clearing its data deletes it, and the developer cannot recover it.
3. Permissions and why
| Permission | When | Purpose and handling |
|---|---|---|
| Camera | When scanning a family QR code | Reads only the QR code in the center of the frame. No photos or video are stored or sent, and the camera stops when the screen closes. |
| Internet, network state | When using Google Calendar, Google sync or the map, and for Wi-Fi sync | Talks to Google services and checks whether the phone is on Wi-Fi. |
| Wi-Fi multicast | When same-Wi-Fi sync is on and the app is on screen | Finds family phones on the same Wi-Fi without going through the internet. |
| Notifications, boot completed | When reminders are on | Schedules event and fee reminders on the device and restores them after a restart. |
The app does not use the microphone or location permissions. Picking a place on the map does not read your location.
4. Ads and payments
The app has no ads and no in-app purchases. The class fee feature only keeps the records and reminders a parent enters; it makes no payments and does not connect to any academy.
5. Sharing with family (only when a parent chooses)
- Family file: sends a schedule file through the app a parent picks in the share sheet (messenger, email and so on). The parent decides the recipient.
- QR code: shows the schedule as QR codes on screen for a nearby family phone to scan. Nothing goes over the internet.
- Same Wi-Fi: when turned on, syncs with family phones on the same Wi-Fi while the app is on screen. Data is locked (AES-GCM) with a family key shared once by QR, so only phones with that key can open it.
- Sending to Google Calendar and syncing through Google: see section 6.
6. Google user data
The app signs in with Google and asks for the permissions below only when a parent turns on sending to Google Calendar or syncing anywhere through Google. Sign-in and access tokens are handled by Google sign-in on the device and are never sent to the developer.
| Scope | Used for | What it does |
|---|---|---|
| calendar.app.created | Sending calendars, creating a family space | Creates, updates and deletes only calendars the app created and the events in them. |
| calendar.acls | Inviting family | Shares a calendar the app created with family emails the parent enters, as viewer or editor. |
| calendar.events | Joining a family space another parent created | Reads and writes only the sync events in that family space calendar. |
- Sending to Google Calendar: event titles, times, repeats and place names are stored in the parent's own Google Calendar.
- Syncing through Google: the whole schedule is locked with the family key and kept in a note event in the parent's own Google Calendar. The key exists only on family phones, so neither Google nor the developer can read it.
- The app does not read the parent's other calendars or events.
- Google user data is never used for advertising, sold, given to third parties or used to train AI models.
- "Stop" in the app stops syncing on that phone, and access can be revoked at any time in the Google Account "Third-party apps & services" page (https://myaccount.google.com/connections).
DayPieces' use and transfer to any other app of information received from Google APIs will adhere to the Google API Services User Data Policy (https://developers.google.com/terms/api-services-user-data-policy), including the Limited Use requirements.
7. Maps and other components
- Map (Google Maps SDK): only when a parent opens the map to pick a place, map imagery is loaded from Google. Place names and child data are not sent. Google's processing follows the Google Privacy Policy (https://policies.google.com/privacy).
- Read-aloud: uses the text-to-speech engine installed on the device.
- Reminders: scheduled on the device, no more than six per child per day.
8. Children
The app is used by parents. A parent opens kid mode for the child, and a parent PIN is needed to leave it. Kid mode has no ads, purchases or outside links. Children's data stays on the device, and the developer collects no personal data from anyone, including children under 14.
9. Third parties and transfers abroad
The developer does not provide user data to third parties or transfer it abroad. When a parent turns on the Google features in sections 6 and 7, data goes to the parent's own Google Account (Google LLC, USA) at the parent's request.
10. Retention and deletion
- Data on the device stays until the parent deletes it or uninstalls the app.
- Events sent to Google Calendar and the sync calendar are deleted when the parent deletes that calendar in Google Calendar.
- The developer holds no user data, so there is nothing to access or delete on our side. For questions, see section 12.
11. Changes
If this policy changes, we will update the effective date on this page and describe the changes.
