Holdy

About this app

Holdy creates a unique identifier for this Android phone.

Open the app, hold your phone upright in your hand for a few seconds, and Holdy builds an ID from the device itself. Copy it when you need a stable per-device identifier. The same phone keeps the same ID if you reinstall.

What Holdy is for
• A simple, hardware-derived device ID you can copy
• The same ID on this phone after reinstall
• A lightweight utility: one screen, no account

What Holdy is not
• Not an account or login app
• Not an ad network
• Not a contacts, photos, or location app

Privacy
Holdy does not ask for contacts, location, camera, microphone, SMS, or storage permissions. It does not show ads. It does not collect your name, email, or phone number. A unique device ID is generated on your phone. Internet is used only to register that this identifier was created so the app can show you the same ID later.

How to use
1. Open Holdy.
2. Hold the phone upright in your hand (not flat on a table).
3. Wait a few seconds.
4. Copy your device ID if you need it.

Holdy is not directed at children under 13.
