Dotbarge: QR Generator & Reader — Privacy Policy
Publisher: Zydeno. Contact: support@zydeno.com. Effective date: 19 October 2026.

Dotbarge works locally. The extension stores data only in your browser (storage.local); nothing is sent to Zydeno or anyone else. There are no analytics, no telemetry, no accounts, no advertising and no remote code. The QR encoder and decoder are part of the extension package, so making and reading codes needs no network connection.

What is stored, only in your browser:
- Settings: theme, interface language, whether the right-click items are shown, and the default look for new codes.
- History: only the codes you save with the star or the Save button (100 by default, 25–200 in Settings). When the history is full, the oldest code is replaced by the new one. Each entry keeps its name, type, the content of the code (for example a web address, a contact card, or a Wi-Fi network name and password), its colours, shape, error-correction level, size and an optional logo picture you added. Browser local storage is not encrypted; do not save codes you would not want stored on this computer.
- A working draft of the form you are filling in is kept in the browser's session memory (storage.session) and is cleared when the browser closes.
- Codes you read are never saved automatically. Pictures you open, paste or drop, and snapshots of a page, are processed in memory and are not stored. In private windows nothing is saved.

Permissions:
- activeTab: after you click the Dotbarge button, use a right-click item or press the shortcut, the extension may read the address of the current tab (to make its QR code) and take one snapshot of the visible part of that tab (only when you choose "Scan this page" or "Read the QR code in this image") to find codes in it. There is no access to other tabs, your browsing history or page content at any other time.
- contextMenus: adds the right-click items "Make a QR code from the selected text", "Make a QR code from this link", "Make a QR code of this page" and "Read the QR code in this image". They can be switched off in Settings.
- storage: keeps the settings, saved codes and the onboarding flag in your browser.
- Downloads (PNG, SVG, backup files) and copying use the normal browser download and clipboard functions after you press a button. The extension never reads the clipboard in the background; a picture is pasted only when you paste it into the reading area yourself.

Backups:
- "Export backup" creates a JSON file on your computer with your settings and saved codes, which may include Wi-Fi passwords and contact details. You decide where to keep or share it.
- "Import backup" reads a file you choose, checks it and shows what will change before anything is written.

Deleting data:
- Delete single codes or all codes in History or Settings; each deletion can be undone for a few seconds. Removing the extension removes its stored data.

Links found in codes are opened only when you press "Open link"; the website's own privacy policy then applies. This policy covers the extension only.
