TASK: Replacement Reminder (Consumable Timer) is an app that reminds you when household consumables need replacing. The developer is Boen.
In one sentence: this app has no server and no account system. Your data stays on your phone. The developer cannot access any of your data.
The app has no backend server and no account or sign-in system. Your list of items, replacement history, places, location coordinates and all settings are written only to a local database on your phone and are never uploaded anywhere.
The app does not use any analytics, tracking or advertising SDK (such as Firebase Analytics, Google Analytics or ad networks). The developer has no way of knowing who you are, what you record, or how you use the app.
The following data is stored only on your device:
| Data | Details |
|---|---|
| Item data | Name, model number, replacement cycle, due date, stock count, purchase link, notes |
| Replacement history | The date of each time you tap "Replaced" |
| Place data | Places you name yourself, location coordinates you set yourself, and Wi-Fi network names you specify yourself |
| Model photos | Photos you take yourself with the camera |
| App settings | Reminder times, free-time window, schedule, appearance settings, language |
| Purchase status | Whether you have purchased Pro, which plan (monthly / yearly / lifetime), and when it was last confirmed with the store |
The app has disabled Android's automatic system backup (allowBackup="false"), so the data above is not automatically uploaded to the cloud by the system and is not automatically transferred when you change devices. It can only be moved between devices through a backup file you export yourself.
Purpose: To tell whether you have returned to a place you set yourself, so reminders go off when you can actually act on them.
How it is handled: Location matching happens entirely on your device. Coordinates never leave the device and are not sent to the developer or any third party.
If you decline: The app still works normally; reminders go off at the fixed time you set instead.
Purpose: If you choose "Wi-Fi mode", the app reads the name (SSID) of the Wi-Fi network you are currently connected to and compares it with the name you set yourself, to tell whether you have arrived at that place.
What it explicitly does not do: It does not scan for nearby Wi-Fi networks, does not record the BSSID or any network hardware identifier, and does not upload network names.
Android classifies reading the Wi-Fi name as a location-related permission, so this feature also requires the location permission.
Purpose: To send replacement reminders and restock reminders.
Purpose: Used only when you choose to take a model photo for an item, through the system camera. Photos are stored only on the device.
Purpose: Used only when you choose to "export a backup", to save the backup file to a location you choose; and to import a backup file you choose.
Purpose: To reschedule your reminders after the device restarts. Without this permission, reminders would disappear after a restart.
These are brought in by the third-party components described below or by the system notification mechanism. The app itself never sends your data to any server.
The app uses only two components provided by Google:
When it runs: Only when you open the "set place location" screen.
What happens: Showing the map requires requesting map tiles from Google; these requests include the visible map area and device information. This data goes to Google, not to the developer.
You can avoid it entirely: If you never set coordinates for a place, this screen is never opened.
Google's handling of this data is governed by the Google Privacy Policy.
When it runs:
Why it checks every time: Without this check, users who have already paid would be treated as not having purchased after changing phones or reinstalling. If the check fails (for example, when offline), the app keeps the status already stored on the device and does not downgrade you to the free version because of it.
What happens: Payments and checks are handled by Google Play. The app does not obtain or store your name, email address, payment method or store account; only the purchase status listed in the table above is kept on the device.
Because these checks are network requests to Google, Google knows that this device has queried the store about this app's products and purchase status. This data goes to Google, not to the developer.
Google's handling of this data is governed by the Google Privacy Policy.
The developer does not share, sell, rent or trade any of your data — because the developer never obtains any data in the first place.
Apart from the third-party services above, the app does not send your data to anyone else.
Your data is kept on your device for as long as you choose.
How to delete: Delete individual items in the app, or simply uninstall the app — uninstalling removes all local data. Because automatic system backup is disabled, no data remains in the cloud.
If you have exported a backup file, it is in the storage location you chose and must be deleted by you.
The app is not designed for children and does not knowingly collect any data from children.
If a change to the app's features requires this policy to change, the developer will update this page and the "Last updated" date above. Significant changes will also be announced in the app's release notes.
