About this app
TinyTrash helps you plan trash pickup in Japan with reminders, a calendar and guides for 71 items. Enter dates from your municipality's official calendar; schedules are not fetched automatically.
YOUR NEXT PICKUP AT A GLANCE
The home screen shows the next date, weekday, waste type and optional deadline from your saved schedule. Mark today's disposal as done, or undo a mistaken entry. Check what is coming up before preparing your household waste.
A CALENDAR THAT FITS YOUR LOCAL ROUTINE
Choose a prefecture and municipality, with an optional neighborhood or collection district. Select waste types from illustrated choices, or name an Other category. Set multiple weekdays every week, or the first through fifth or last occurrence of a weekday within a month. Add an optional cutoff time and check each type's next date before saving.
Use the calendar for one-day changes: skip a collection, add an extra pickup or move it to another day. Enter holiday and year-end changes from your municipality's latest notice. Selecting a region does not fill in its collection schedule.
LOCAL REMINDERS THE DAY BEFORE OR ON THE DAY
Turn notifications on explicitly, grant OS permission, and choose the time and waste types. Local notifications are delivered by your device's OS. Up to 60 pickups are scheduled, within a maximum 180-day window, with a renewal notice. Open the app before the reservation expires and follow its renewal guidance. Delivery can be delayed or prevented by device settings, battery saving or OS limits; reminders are not a guarantee against missed pickups.
A SORTING GUIDE FOR 71 ITEMS
Search by item name to check typical collection destinations, preparation steps, safety notes and questions to ask the collection service. Materials, remaining contents and size can change how an item must be handled. Read the precautions for items such as rechargeable batteries and aerosol cans.
The guide is general reference information for Japan, not an automatic classifier or an official ruling for your chosen municipality. Always follow local instructions for waste categories, designated bags, collection dates and drop-off points.
GET STARTED
Use the official calendar to register your region, waste types and repeating days. Check the next dates, then enable reminders if needed. Adjust exceptions in the calendar. Useful after a move or for alternating recycling dates, without an app account.
LANGUAGES AND APPEARANCE
Nine languages, seven theme colors, and light or dark appearance. Region names and your own entries keep their original text.
FREE FEATURES AND ADVERTISING
TinyTrash 1.0.0 is free with advertisements. This version does not offer in-app purchases, subscriptions, one-time purchases, ad-removal plans or free trials.
STORAGE AND PRIVACY
Settings, schedules and completion records stay on your device. No app account is required; there is no cross-device schedule sync. Dates and reminder times use Japan Standard Time (JST).
Ads use Google AdMob. Firebase Analytics collects standard data for every user from first launch, with no in-app opt-out. Region names, collection dates, entered names and search terms are not custom-sent. The initial release is distributed only in Japan. Required advertising consent screens and iOS tracking permission are handled separately from standard Analytics collection. The app has no setting to reopen advertising consent. You can change iOS tracking permission in OS settings.
Screenshots show sample regions and schedules. TinyTrash is not an official municipal app. Follow current local instructions when disposing of waste.
