Full GDPR compliance - before first use of your account you must accept the Terms of Service and the Privacy Policy. Google Analytics consent is separate, optional, and can be withdrawn any time from Account Settings.
New legal pages - complete Privacy Policy (/privacy/) and Terms of Service (/terms/) in three languages cover the data controller, legal bases, retention periods, recipients and all your GDPR rights.
Account settings - a new dashboard section displays the version and date of your consent and lets you turn Google Analytics on or off with one click.
Permanent account deletion - you can delete your account yourself from Account Settings (confirmation by typing DELETE required). All QR codes, folders and statistics are removed irreversibly via database cascade deletion.
Consent audit trail - terms version, timestamp and browser type are recorded on consent. If the terms version changes, the app automatically requests fresh consent.
Styled previews in My Codes - saved QR codes now display with their actual design in the overview, including eye colors, gradients, logo and frame, instead of a generic black-and-white preview.

v10.011. 5. 2026
QR generator redesigned into a tabbed interface - the workflow is split into 6 steps (Content, Templates, Colors, Shapes, Logo, Export) that guide the user from data to download without endless scrolling.
QR preview (canvas, scan bar, score, strictness and size/ECL popovers) stays permanently visible in the right column, so changes are reflected instantly regardless of the active tab.
The active tab is highlighted with a blue background, underline, and a colored Lucide icon. Tab headers have a clean professional look without distracting effects.
Logo selection (upload, presets and size) has its own new Logo tab, separated from the other design options for better clarity.
Template gallery now reliably shows horizontal scroll arrows for overflowing categories - thanks to ResizeObserver they are recomputed when the tab becomes visible.
Download and save controls (format, primary button, Save to history, and more options) moved into the Export tab, leaving the preview column clean and focused on the QR code.
v9.97. 5. 2026
New type: GS1 Digital Link - encodes a product via a standardized GS1 URL. Supported identifiers: GTIN, CPV, batch, serial number, expiry, best before, pack date, country of origin, weight, and custom application identifiers. GTIN input is validated and the URL is built automatically.

Per-code stats in detail - the code card shows a sparkline, scan counts for last 30 days, today, unique visitors and top countries. The Full stats button opens the dashboard filtered to that specific code.
Free GeoIP - locally hosted MaxMind GeoLite2 database identifies the country and city of each scan in microseconds, without any external call. EU customer data stays in the EU.
Scan CSV export - the Export CSV button downloads scan data (time, country, city, device, browser, OS, referer) for the selected period; up to 50,000 rows.
Privacy by design - no cookies, no third-party trackers, daily IP-hash rotation, referer query strings are stripped before storage (prevents token leaks).
v9.728. 4. 2026

Simplified save dialog – target URL is taken directly from the main input field, without duplication.
v9.624. 4. 2026
vCard now lets you enter first and last name separately (stored as the structured N field) and a new Job title field (TITLE). For older saved codes, the full name is automatically split at the space.
Added second phone and second email with type selection (Mobile/Work/Home/Fax for phones, Work/Personal for emails). The type is stored in the QR code as the vCard 3.0 TYPE= parameter so contact apps on the phone distinguish the fields correctly.
v9.522. 4. 2026
Expanded module style options from 4 to 9 - added Classy, Classy rounded, Diamond, Heart, and Star styles. Select them in the Design → Module style panel.

Code card actions on the dashboard are now visible buttons side by side (Edit, Rename, Move, Delete) instead of a hidden kebab menu. Folder chips show rename/delete icons on hover.

v9.015. 4. 2026
New dedicated "My Codes" page (/my-codes/) with sidebar navigation, folder management, QR thumbnails, search, type filter, sorting, bulk selection, and bulk actions (delete, move to folder).

Saved QR code preview thumbnails are generated client-side with in-memory cache using a pure payload builder (no DOM dependency).

The editor now supports the ?code= URL parameter for automatic loading of a saved QR code on page open.
The "My Codes" button in the header now navigates to the dashboard page instead of opening a modal overlay.
v8.113. 4. 2026
QR type selection icons replaced with Lucide Icons - standard, clear line icons (link, mail, phone, map-pin, bitcoin, share-2, etc.) instead of previous custom pixel-art symbols.
Text in frames and templates is now vertically centered with pixel accuracy using actualBoundingBoxAscent/Descent measurement, eliminating font-dependent offset caused by dominant-baseline='middle'.
v8.010. 4. 2026
Added new eye style "Soft square" for outer frame and inner dot, matching the rounded square look from the provided reference.
Payment fields now include browser autofill metadata (name/autocomplete), so Chrome better offers to save and reuse IBAN/account.
The "Split IBAN to CZ account" action now appears only in IBAN mode and immediately shows clear feedback for invalid CZ IBAN.
SPD conversion buttons now perform a visible action: switch mode and immediately show converted fields or clear guidance for invalid CZ IBAN.
Payment amount fields now enforce strict format (positive number, max 2 decimal places) including comma-to-dot normalization.
Recipient name and note in SEPA now validate EPC characters and display a live remaining character counter.
SPD conversion is now bidirectional: you can calculate IBAN from a Czech account and split a valid CZ IBAN back into prefix/account number/bank code.
Payment forms now continuously validate IBAN and BIC/SWIFT for SPD and SEPA fields including inline error highlighting.
Payment QR generation is blocked when SPD/SEPA data is missing or invalid, and a centered warning with instructions is shown in the preview.
In SPD account number mode, the Prefix / Account number / Bank code fields are stacked vertically, so the Account number field no longer gets clipped in narrow panels.
Date and time fields on the Event card have the same design as other inputs, and Start/End are stacked vertically for better readability in narrow panels.
The birthday field in vCard now matches the design of other input fields.
The Galaxy template was adjusted for higher scan reliability while preserving the visual style.
Score scale labels are aligned to actual boundaries (0/60/75/90/100), so the needle position visually matches the displayed score.
