addy.io

addy.io is a email application developed by Stjin, packaged as a single Android APK of version 0.0 weighing in at 17.64 MB. The package targets Android 4.1+ and above. Below you'll find the publisher's own description, a quick spec sheet, and a short buyer-beware checklist so you know exactly what you're installing before tapping download.

1. Only download through the button on this page — never from third-party mirrors or shortened links, which are the most common way malware spreads.
2. File size is a light 17.64 MB, so it installs quickly even on modest connections.
3. This build is signed by "Stjin" — always verify the developer name matches what's listed on the app's official store page before installing an update.
4. After install, Android may prompt you to allow "Install from unknown sources" — approve only this one install, then revoke the permission in Settings > Apps > Special access.
5. We link directly to the APK file or the publisher's repository; we do not modify the binary. Always run a virus scan after any sideloaded install.

Easily create and manage your addy.io aliases, recipients and more from your phone, tablet or wearable with the addy.io app.

Is addy.io free to download?
Yes. The APK file linked from this page is free. The developer may offer in-app purchases once installed, but obtaining the installer itself costs nothing.

What Android version does addy.io require?
Android 4.1+ or newer. Installing on older devices may cause crashes or refuse to install.

Is addy.io safe to install?

How do I update addy.io?
Install the newer version on top of the old one — Android will keep your data. If the signature differs, uninstall first (you may lose local progress).

Why is the app not installing?
Common causes: not enough storage, an older Android version than 4.1+, or a conflicting build already installed. Free up space, check your OS version, and uninstall any previous copy before retrying.

1. Tap the Download APK button above and save the file to your device.
2. Open your device Settings → Security (or Apps → Special access → Install unknown apps) and allow your file manager or browser to install unknown apps for this one file only.
3. Open the downloaded host.stjin.anonaddy.apk file from your Downloads folder.
4. Tap Install and wait for Android to finish.
5. Open «addy.io» by Stjin and grant only the permissions it actually needs.
6. Revoke the "unknown sources" permission once you are done installing.
