Bug reports, feature requests, partnership inquiries, or just a friendly hello — we read everything.
Most questions we receive are already answered somewhere on the site. These three pages solve the majority of them, and they are available instantly:
Pricing, expiry, error correction levels, export formats and why a code will not scan.
WiFi, vCard, restaurant menu and event QR codes, plus printing and sizing advice.
What stays on your device, what we never see, and how to clear your local history.
If you believe you have found a vulnerability that could expose another person's data, please email [email protected] with the subject line "Security" before disclosing it publicly. Because QR Tool Studio performs every operation locally in your browser, the attack surface is limited to the static assets we serve — but we take reports seriously and will respond within one business day.
