QRápido: Gerador e Leitor de QR
Terms of Service
These Terms of Service ("Terms") govern the use of the QRápido: QR Generator and Scanner app (the "App"), offered by Duo Dev ("we"). By installing and using the App, you agree to these Terms and to the Privacy Policy. If you do not agree, do not use the App.
1. What the App is
QRápido creates and reads QR Codes. You can generate QRs for Pix (static), Wi-Fi, WhatsApp, links, text, contacts, email and phone; read QRs with the camera or from a photo; save as PNG and share; and keep a local history with favorites. The Premium plan adds customization (colors, logo and dot shape), SVG and PDF export, batch generation from CSV, unlimited history, saved templates and ad removal. The App runs on your device, with no sign-up.
2. Important notices: Pix and third-party QRs
- The Pix QR is static and does not confirm payment. The payer and the recipient must check the transaction in the bank's app. QRápido is not a financial institution and does not process or intermediate payments and does not verify whether the key, name or city entered are correct: you are responsible for the data you type. Test the QR before publishing it.
- Be careful with third-party QRs. The App shows the content read and does not open anything by itself, but it cannot guarantee that a link, Wi-Fi network, contact or Pix code read is safe or genuine. Scams with fake QRs exist: check the address, the recipient and the amount before continuing.
- A customized QR may fail in some readers. The editor's read test helps, but does not guarantee that every phone will read a QR with colors, logo or dots different from the default.
3. Permitted use
You must be 18 or older (or use it with the authorization of a legal guardian). It is forbidden to use the App for fraud, scams, phishing, distribution of illegal or misleading content, a QR that impersonates another person or company, violation of third-party rights, or any activity contrary to the law. You are solely responsible for the content you generate and share.
4. Plans, subscriptions and purchases
- Free: includes the basic features and shows ads. The history keeps up to 30 items that are not favorites: when you save a new one, the oldest (non-favorite) is deleted. Favorites are never deleted and do not count toward the limit.
- Premium: weekly, monthly and annual plans (auto-renewing subscriptions) and lifetime (one-time payment). Prices and conditions are those shown on Google Play at the time of purchase (reference values: R$ 6.90 per week, R$ 14.90 per month, R$ 79.90 per year and R$ 119.90 for lifetime; they may vary and be updated).
- Free trial: the annual plan may offer 3 free days to new subscribers. If you do not cancel at least 24 hours before the end of the trial, the subscription starts and billing is done by Google Play.
- Renewal and cancellation: subscriptions renew automatically until canceled. Cancel any time on Google Play (Profile › Payments and subscriptions › Subscriptions); access continues until the end of the period already paid. Billing, refunds and the right of withdrawal follow Google Play's policy and consumer protection law.
- Lifetime: one-time payment, with no renewal, tied to your Google account and valid while the App is available. It can be recovered in "Restore purchases".
- When Premium ends: the QRs you customized remain saved; to edit the customization you need to renew. The history goes back to the limit of 30 non-favorite items (the excess is deleted when you save or read a new QR).
- Restore purchases: in Settings › Restore purchases (or on the paywall), with the same Google Play account.
5. Your data and your history
The history, favorites, templates and preferences stay only on your device; there is no synchronization or backup made by us. If you clear the app's data, uninstall or change devices, they may be lost. See the Privacy Policy.
6. Ads
The free version shows third-party ads (Google AdMob). We are not responsible for the content of ads or for the websites and services that they, or the links you read, open. You can choose how your data is used in ads in Settings › Ad and privacy preferences.
7. Intellectual property and trademarks
The App, its brand, icon, texts and code belong to Duo Dev. We grant you a personal, limited, revocable and non-exclusive license to use the App. The QRs you create are yours. "QR Code" is a registered trademark of DENSO WAVE INCORPORATED; "Pix" is a trademark of the Central Bank of Brazil; "WhatsApp" is a trademark of Meta Platforms, Inc.; "Wi-Fi" is a trademark of the Wi-Fi Alliance; "Google", "Google Play" and "AdMob" are trademarks of Google LLC. They are cited only to indicate features and compatibility; the App is not made or endorsed by those owners.
8. Availability and changes
We may update, modify, limit or discontinue the App or part of it, including the prices of new purchases and subscriptions. The App depends on your device and, for purchases, ads and opening links, on the internet and Google services; we do not guarantee uninterrupted operation.
9. Limitation of liability
The App is offered as is. To the extent permitted by law (and without removing rights that the Brazilian Consumer Protection Code ensures), Duo Dev is not liable for: payments made or received with incorrectly typed data; scams and content of third-party QRs, links, Wi-Fi networks or contacts; customized QRs that some device does not read; loss of data from the device; or unavailability of third-party services (Google Play, AdMob, internet).
10. Termination
You may stop using the App at any time by uninstalling it (and canceling subscriptions on Google Play). We may suspend access for anyone who violates these Terms.
11. Changes to the Terms
We may update these Terms. When a change is relevant, we will notify you through the App or on this page. The date of the last update is at the top; continuing to use the App after the change indicates agreement.
12. Governing law and venue
These Terms are governed by the laws of Brazil. The courts of the consumer's domicile are chosen to settle any dispute.
