Information we process
The app processes Datamatrix barcode strings on your device to decode and display the information contained in the barcode.
We do not collect barcode data from your device automatically.
If you use collection/checklist features, that data is stored locally on your device as part of normal app use. Label previews are also generated locally on-device.
Technical note: the app supports Royal Mail JGB-format barcodes.
Support emails
If you contact us at beta@stampdecoder.app, we will receive your email address and the contents of your message. We use this only to respond to your request and to improve the app.
Third-party services
We do not use third-party analytics in the app at this time.
Children
The app is intended for a general audience and is not directed to children. We do not knowingly collect personal information from children.
Your choices
You can stop using the app at any time. If the app stores any data locally on your device (for example, user preferences), removing the app will remove that local data.
