Your family’s digital security. Private by design. Merv turns your accounts, apps and online activity into one clear Digital Health Score — so your whole household, teens included, can see their risks and fix them, together. And because Merv runs entirely on your device, your personal data is never collected, shared or sold. Not a promise. An architecture. ONE SCORE THAT MAKES SECURITY MAKE SENSE Cybersecurity is invisible until it isn’t. Merv makes it visible — and fixable. ● Digital Health Score — one number that shows where you stand, and why ● Map your digital life — accounts, apps, devices and networks, analysed securely on your device ● See your public exposure — find your details in known data breaches ● Act, don’t worry — guided action cards walk you through fixing what matters most ● Learn as you go — on-device guidance written for every generation, not just the tech-savvy THE WHOLE HOUSEHOLD, ONE PICTURE Add up to six people. Everyone’s score rolls into a single Family Score — a living picture of how protected your home is. Each person keeps their own private view: you see the family picture, never each other’s details. Support your parents, your kids, your partner — without ever monitoring them. TEENS, PRIVATE BY DESIGN Teens get their own Merv, with age-matched content, safety tools, and the most protective settings on by default. It works from a declared age range — a band, never a birthday, name or ID — and collects no personal data. Teens choose what they share with the family. Protection without surveillance. YOUR DATA NEVER LEAVES YOUR DEVICE Merv is AI-native and runs on your iPhone’s own intelligence. All checks happen locally; only anonymous threat lists come down to your phone. Merv can’t see your data, so it can never lose it, share it or sell it. That’s not a policy — it’s how Merv is built. CLARITY, NOT ALARM No fear, no jargon, no nagging. Merv explains your exposures in plain language, shows you what to fix first, and helps every member of the family stay confident and independent online. WHAT’S INCLUDED ● Free — your Digital Health Score (as a range), education, Merv Chat Q&A, a breach report for one email address, and QR code safety checks ● Premium — your fine-grain score, deeper education, premium Merv Chat, breach reports for up to ten email addresses ● Household — up to six members, with a combined Family Score alongside each person’s own WHY FAMILIES TRUST MERV ● GDPRkids™ Privacy Assured Shield by PRIVO ● COPPA Safe Harbor Certification by PRIVO ● Common Sense Privacy Seal Verified (97% Score) ● Aligned to the NIST Cybersecurity Framework (CSF 2.0) PRIVO is an independent third party dedicated to safeguarding children’s personal information online.

Verdict
The clearest difference is in-app purchases: Flash Charge HK at none against Merv's 3. Flash Charge HK also leads on iOS requirement (14.0 vs 26.5). Merv's advantage is update cadence (every 2 weeks vs every 2 months). On price, ads and device support there is nothing between them.
