Check suspicious links, QR codes and messages before you act. ScanLens helps you review: • Links and final destinations • SMS, email and chat messages • QR codes and supported barcodes • Links found in screenshots or images How it works 1. Paste or share a link or message, scan a QR code, or choose an image. 2. Review the content before sending it. 3. ScanLens returns a SAFE, SUSPICIOUS or DANGEROUS result with reasons and practical next steps. Built for deliberate checking • No automatic scan when content is shared or extracted from an image • Screenshot OCR runs on your device and stays editable before you submit a link • Local History stores a privacy-minimized record and supports item deletion and Clear History • Share Extension saves content for review; you open ScanLens to continue • Camera recovery and duplicate protection help prevent repeated scans No ads ScanLens 1.7 contains no banner, interstitial or rewarded ads and no advertising consent screen. Lifetime ScanLens Lifetime is a one-time, non-consumable in-app purchase. The current localized price is shown by the App Store. Restore Purchases is available in Settings. Server-authorized starter access and non-ad credits remain separate from Lifetime. Privacy and control ScanLens does not require an account for basic scanning. You decide when to submit content. Links may be requested by the ScanLens service, and redirect destinations may receive the requested URL. Clear History and shared-content controls affect local data only; remote privacy requests are available in Settings. ScanLens provides risk indicators, not a guarantee. When in doubt, use the official website or known contact details before signing in, paying or sharing information.

Lockstead helps limit access to selected apps before you lend your iPhone or iPad. Lockstead is an on-device app lock and privacy guard for the iPhone or iPad you hand to a child, friend, or family member. Choose the apps you want to protect, set a six-digit PIN, and see the current protection status at a glance. Lockstead works without an account, backend server, analytics SDK, or usage-data upload. LOCK AND BLOCK • Lock selected apps to prevent them from launching until you turn protection off. • Use category, allow-only, and Guest Mode rules. • Temporarily allow access and automatically restore protection when time is up. PROTECTION THAT FITS THE MOMENT • Schedule a daily protection window. • Use allow-only mode and category rules. • Start Guest Mode before handing over your device: only chosen apps stay available, all other apps are blocked, and everything restores automatically. • Use Lockstead Shortcuts to strengthen protection. Unlocking always requires authentication inside Lockstead. PRIVATE ACCESS • Protect settings with a six-digit PIN. • Optionally unlock Lockstead with Face ID or Touch ID. PRIVACY BY DESIGN • No account. • No server. • No advertising or analytics SDK. • No usage-data upload. Your PIN and protection configuration stay in the app’s local container on your device. FREE CORE, OPTIONAL VIP Core protection for one selected app is free. VIP adds multi-app management, advanced rules, Guest Mode, app-removal controls, premium themes, and alternate Lockstead icons. Lockstead uses Apple’s Screen Time technologies and requires Screen Time authorization. Family Controls, Managed Settings, and Device Activity are used solely to let users configure and enforce app restrictions on their own devices.
