m.i.n.a.r. — Grandapp

Privacy Policy

Last updated: August 10, 2026

Grandapp is an Android toolbox built by an independent developer (m.i.n.a.r.), designed to be usable by people who find modern phones difficult. This page explains, in plain language, what data the app touches and what it does with it. The short version: Grandapp has no server backend, no account, and no analytics or advertising SDK. Everything it remembers stays in its own private storage on your phone. It reaches the network for exactly one thing, described below, and that request contains nothing about you.

Network access

NetworkExchange rates only

Grandapp declares the INTERNET permission for one feature: the "Money" section of the converter, which needs to know what a euro is worth today. The app asks a public rates service (frankfurter.app, which publishes the European Central Bank's daily reference rates) for the current figures, at most once every twelve hours. The request carries no identifier, no account and nothing about you or your phone; it is simply a request for today's rates. The answer is cached on the device so the converter keeps working offline. Nothing is ever sent to the developer, and no other part of the app uses the network.

Camera

Magnifier and mirrorLive only, never recorded

The magnifier and the mirror show you the camera picture enlarged, and that is the only reason Grandapp asks for the camera permission. Nothing is recorded and nothing is saved. The magnifier's "freeze" button holds the current frame in memory so you can read it without a steady hand; that frame is discarded the moment you unfreeze or leave the screen.

QR reader, scanner and read-aloud captureNo permission at all

These three use Google's own scanner screens, which run as Play Services activities and open the camera themselves. Grandapp's manifest asks for nothing on their behalf, and the app only receives the result you confirmed: the text of a code, or the page you scanned.

Data that stays entirely on your device

These are kept locally to make the app work, and never leave your phone:

Reading a sheet out loudLocal only

Text recognition runs on the device, using the on-device model provided by Google Play Services. The photograph and the recognized text are never uploaded, and neither is kept: the text lives only while that screen is open. The reading voice is your phone's own text-to-speech.

The people you callLocal only

Grandapp never asks to read your contacts and never sees your address book. When you choose someone for the SOS button or for a quick-call square, Android's own contact picker hands the app one single phone entry, the one you selected. Only that name and number are saved, in the app's private storage. Calls are placed by opening your phone's dialer with the number already entered, so you always press the call button yourself.

Reminders and the timerLocal only

Medicine reminders and the countdown are scheduled as ordinary Android alarms on your device, and their notifications are posted by your phone. The names and times you enter are stored locally. This is what the notification and alarm permissions are for, and nothing else.

Your note, your settings, your toolsLocal only

The quick note, the ruler calibration, your favorite tools, the theme, the text size and every other preference are stored in the app's own private storage. Sharing a note or a scanned document only happens when you press the share button and choose where it goes.

Torch, level, compass and phone infoNo permission at all

The torch uses the system flashlight control, and the level and compass read motion sensors, none of which requires a permission or reveals anything about you. Battery and storage figures are read from the system and only shown on screen.

Home screen mode

Grandapp is not a home screen until you deliberately turn that on in the advanced settings. Until you do, the component that would let Android treat it as one is disabled, and the app never appears in the list of home apps. Switching it back off is done from the same place, and always sends you to Android's own home-app chooser so the phone is never left without one.

The list of installed appsNo permission at all

To draw a home screen the app has to know which apps have an icon. It asks Android only for that: the apps that can be launched. It deliberately does not use the broad "query all packages" permission, so the full inventory of what is installed on the phone is never available to it. The list is used to draw tiles and nothing else, and it never leaves the device.

Removing an appGrandapp cannot delete anything

The "remove this app" button hands the request to Android and stops there. Android shows its own confirmation, and nothing is uninstalled unless you accept it. Grandapp declares the permission that allows it to open that confirmation, which is not the same as being able to remove software: it has no way to delete an app on its own, and never asks to.

Notification dotsOptional, off unless you allow it

The dot on an app tile means that app has something waiting. Reading that requires a special Android access that you have to grant by hand, from a system settings page, and Grandapp only ever points you at that page from the advanced settings, after the home screen mode is on. If you never grant it the app works exactly the same, without dots.

When it is granted, Grandapp reads which app has a pending notification, plus the title and the one line of text that notification already shows on your screen. Holding a finger on an app with a dot displays that title and line, so you can see what is waiting without opening anything. Nothing else is read: not the sender, not the rest of a longer message, not attachments, not images, and not how many notifications there are.

All of it is held in memory only, for exactly as long as the notification itself exists on your phone, and it is dropped the moment the notification is dismissed or the app stops running. It is never written to storage, never added up over time, and never sent anywhere.

What Grandapp does not do

Children's privacy

Grandapp is not directed at children and does not knowingly collect personal data from anyone, of any age. The app has no account system and no user-identifying network traffic, so there is no mechanism by which it could.

Data retention & deletion

Everything described above lives in your device's local storage. Uninstalling Grandapp (or clearing its app data from Android settings) permanently deletes all of it. There is nothing on our end to delete, because nothing is stored on our end.

Changes to this policy

If this policy changes, the "last updated" date above will change accordingly. Meaningful changes will also be reflected in the app's release notes.
