Notchrow — Chính sách quyền riêng tư

Effective date: 6 November 2026. English is the controlling text.

Developer: PocketFoundry. Contact: [email protected]. Package: com.hpiapp.meterlog.notchrow.

Notchrow is a household meter log for Android. You type electric and water readings, prices, and optional notes. This policy describes what this version of the app actually does.

No account

The app does not ask you to register or sign in. PocketFoundry does not keep a Notchrow profile on a server.

Data stored on your device

Home names, meter names, meter type, unit, the prices and optional daily standing charge you type, readings (date, register values, optional note, and whether the meter was marked replaced), sample flags, your in-app language choice, reminder settings, and whether the one-time unlock is recorded on this phone are stored in a JSON file in the app’s private storage. Notchrow does not upload that file. Android backup is turned off, so the file is not copied into cloud backup.

Purchase

An optional one-time Google Play product, notchrow_more_meters, raises the limit from one home and two meters you created to six homes and twenty-four meters, and it unlocks CSV export. It is not a subscription. Notchrow uses Google Play Billing to ask whether the product is owned and to show the price Play returns. The app does not receive your card number. Sample homes and sample meters do not count toward the free limit.

CSV export

After that purchase, export writes a file on your device and opens the Android share sheet. The file goes only where you send it. Column headers are English. PocketFoundry does not receive a copy.

Notifications

If you turn on a reading reminder, the app asks for notification permission and schedules a local notification for the day or interval you chose. The reminder is created on the device. It does not read the meter and it does not send the reading to a server. You can turn reminders off or deny the permission. Logging still works without it. The WorkManager library used for that schedule also declares a wake lock, network-state access, boot completion, and a foreground-service capability. Notchrow does not run its own ongoing foreground task and does not upload data to deliver the reminder.

Permissions and network

The app declares Internet and Billing because Google Play Billing uses them. It may request notifications, as described above. It does not request location, camera, microphone, contacts, or photos. There is no advertising ID. There are no ads and no analytics SDK. The app does not connect to a utility and does not look up a tariff.

Sharing

The app does not sell your readings. The only way a reading leaves the phone is if you share the CSV yourself, or if Google Play processes the optional purchase. PocketFoundry does not operate a server that receives the log.

Children

Notchrow is not directed at children under 13.

Retention and deletion

Readings stay until you delete them in the app or uninstall the app. Uninstalling removes the private file. Removing the sample home deletes only rows still marked as samples. A new phone does not receive the old file.

Not a bill

Prices and the estimate are numbers you enter or that the app calculates from those numbers. Notchrow does not claim the estimate is a bill or that it will match an invoice.

Changes

If these practices change, this page will be updated and the effective date revised.
