Every answer, in one place.

In order of likelihood:

• Contrast. Very dark backgrounds with dark-colored modules reduce the scanner's contrast budget. Bump the background to a lighter tone or increase the QR fill's brightness.
• Logo too large. Logos shouldn't cover more than ~25% of the QR area. Qito automatically boosts error correction when a logo is present, but huge logos will still fail on some scanners.
• Error correction. Bump ECC from L/M to Q or H in Style → Error correction. This adds redundancy at the cost of module density.
• Preview before exporting. Qito shows a scan-confidence meter in the editor. If it reads "Risky" or "Poor", adjust before exporting.

Make sure Qito has camera permission: Settings → Qito → Camera, or the equivalent on Android. If granted and still failing, try: better lighting, holding the phone 8–12 inches from the code, and ensuring the code fills at least half the viewfinder frame. Older devices may struggle with highly-stylized codes; switch to the "Classic" preset on the creator side for maximum compatibility.

Yes, in both directions. You can generate a Wi-Fi QR from Create → Wi-Fi, entering SSID, password, and encryption (WPA/WPA2/WPA3/Open). When you scan a Wi-Fi QR, Qito decodes it to show the network name, password, and (on iOS 11+) offers to join with one tap.

Yes. Create → Crypto supports plain BTC/ETH/SOL addresses and chain-specific payment URIs (bitcoin:, ethereum:, solana:) with optional amount. Regional payment QRs — UPI (India), PIX (Brazil), PayNow (Singapore), PromptPay (Thailand) — each have their own dedicated creator.

Install Qito, open Settings → Pro, and tap Restore purchases. The app asks Apple or Google for your past purchase history and re-grants the entitlement. You must be signed into the same App Store / Play Store account you used to buy originally.

Subscriptions are managed by Apple or Google directly — we don't touch them. To cancel:

• iOS — Settings app → your Apple ID → Subscriptions → Qito Pro → Cancel.
• Android — Play Store app → profile icon → Payments & subscriptions → Subscriptions → Qito Pro → Cancel.

You keep Pro benefits until the end of the current billing period.

Refunds are handled by Apple and Google per their standard refund policies. On iOS, request via reportaproblem.apple.com. On Android, via Play Store → My orders → Request a refund. If either store declines and you feel there's a legitimate issue with the app itself, email us and we'll advocate for you.

Both, at your choice. Monthly ($1.99) and Yearly ($9.99) are auto-renewing subscriptions. Lifetime ($39.99) is a one-time, non-consumable purchase that never expires and unlocks every current and future Pro feature.

Yes — as long as you use the same App Store or Play Store account. Lifetime is tied to your store account, not the device. New phone, same Apple ID → Restore Purchases → Pro is back.

Locally on your device, inside Qito's app sandbox, via the system's SharedPreferences. It is never transmitted off-device by Qito. This is a deliberate privacy choice.

Settings → Data → Export backup produces a single JSON file containing every saved QR, its payload, and its style. Save it to iCloud Drive, Google Drive, email it to yourself — whatever sharing service you trust. On a new device, install Qito and use Settings → Data → Import backup.

Yes, via the backup JSON. The format is platform-agnostic. Export from one, transfer the file however you like, import on the other. Since Qito doesn't run a server, there's no automatic sync — but the JSON round-trip is fully lossless.

Yes. Uninstalling removes the app sandbox on both iOS and Android, including all Qito data. This is a platform behavior, not something Qito controls. If you hadn't exported a backup before uninstalling, the data is unrecoverable — there is no cloud copy. We recommend exporting a backup after any major session.

iOS — long-press an empty spot on the home screen → tap the + in the corner → search "Qito" → choose a size. The widget shows the QR you've "pinned" in the app (tap a saved QR → Pin as Widget).

Android — long-press an empty home-screen spot → tap Widgets → scroll to Qito → drag the "Pinned QR" tile onto the home screen.

That's the empty state. Open Qito, save or select a QR, and tap Pin as Widget. Within a second or two, the widget re-renders with your QR.

Yes. Qito ships a StandBy-compatible accessoryInline and accessoryRectangular layout. On iPhones in StandBy mode, the widget renders the pinned QR full-width with a monochrome palette suitable for night view.

The Qito launcher icon includes a monochrome layer, so it tints to match your Material You palette on Android 12+. The widget itself uses brand colors; tinting the widget to system colors is on the roadmap.

Nothing personal. No email, no account, no usage analytics, no crash reports. Your QRs and history live exclusively on your device. See the full privacy policy for the byte-level audit.

Settings → Clear history removes everything. For total wipe (including settings and the Pro entitlement cache), uninstall the app. On iOS you can also use Settings → General → iPhone Storage → Qito → Offload app which preserves settings; Delete app wipes everything.

Only three: (1) Apple StoreKit / Google Play Billing, for in-app purchases. (2) Google AdMob, on the free tier only — it goes away when you upgrade to Pro. (3) Google Fonts, once on first launch to fetch the Inter typeface. No analytics SDKs, no crash reporters, no experimentation frameworks.
