Automatically store your contacts to your SD card
About this app
This app is meant for users that don't want to synchronize their contacts online, but want to keep them local to the phone. Though there is a problem, if you brick your phone, you might lose all your contacts. With this app, you will have a backup of your contacts stored on the SD card. You can take it out and import the contacts into your new phone.

How to install this safely
How to verify the file you downloaded
Before you install anything, confirm the file is the one described here. On a computer, run shasum -a 256 your-download.apk (macOS or Linux) or certutil -hashfile your-download.apk SHA256 (Windows), then compare the output character-for-character with the SHA-256 on this page. If a single character differs, the file is not the build we recorded — delete it.
What the signing certificate proves
Every Android app is signed with a private key that only its developer holds. The fingerprint on this page is a hash of the matching public certificate, and it proves continuity rather than identity: it tells you a build came from whoever signed the earlier ones. Android enforces this at install time — if a package claiming to be cx.vmx.sdcontacts is signed with a different key, the system will refuse to install it over your existing copy. A fingerprint that changes between releases is worth pausing on, because a repackaged app that has been modified by someone else cannot keep the original signature.
How to roll back to an earlier version
No earlier build is on record for SD Contacts, so there is nothing to roll back to yet. When a second version is published, this section will explain how to move between them safely.
Why we list sources instead of hosting everything
The official store channel is almost always the right choice: it updates automatically and carries the publisher's own distribution guarantees. A direct APK is useful when a device has no store access, when a rollout has not reached your region, or when you need a specific version — and only when the publisher has authorized that copy. APKBrowse does not list pirated, cracked, or unauthorized rebuilds of SD Contacts, and a listing is removed when the evidence for it stops holding up.

Permissions Required
What each permission lets SD Contacts do. A highlighted one is worth a second look — not necessarily wrong, just worth asking whether this app needs it.
Previous Versions
No earlier build is on record — this is the first release we have listed.
The signing certificate fingerprint for this release is on record, so a build that does not match it did not come from this publisher.
