Privacy Policy

Last updated: June 29, 2026

ReMatter (“the app”, “we”) is a local-first utility for archiving the Matter commissioning QR codes that ship on smart-home devices. This policy explains what data the app handles and why. The short version: your data stays on your device, and we do not operate any servers that receive it.

What we store, and where

When you scan or enter a Matter pairing code, ReMatter saves the decoded data (such as the device discriminator, passcode, and a label you choose) in a database stored locally on your device. This is the only copy. We have no cloud, no account system, and no server that receives or syncs your devices.

If you uninstall the app without making a backup, this data is deleted by the operating system.

Camera

ReMatter uses your device camera only to scan QR codes while you have the scanner open. Camera frames are processed on-device to read the code. Images are not stored, uploaded, or transmitted anywhere.

Backup & Restore

ReMatter offers an optional Backup & Restore feature. When you create a backup, the app writes a file that you save or share through your device’s own sharing options (for example to your Files app or cloud drive of choice). We never receive this file. Where it goes after you export it is governed by whichever service you choose to store it in.

Purchases

The Backup & Restore feature is unlocked by a one-time in-app purchase. Purchases are processed through Google Play Billing and managed using RevenueCat, our purchase infrastructure provider. To validate and restore your purchase, these services process limited data such as a Play purchase token, an anonymous app-user identifier, and basic device and country information. They do not receive any of your archived Matter codes.

What we do not do

• We do not collect analytics or usage tracking.
• We do not show ads.
• We do not sell, rent, or share your data.
• We do not create user accounts or ask for an email address.

If this policy changes, we will update the date at the top of this page. Material changes may also be noted in the app’s release notes.
