Kizoona

Kizoona is a private chat, family-friendly by design. Two separate decisions shape it. Connecting — grown-ups decide. Every new contact needs a grown-up on BOTH sides to approve, not just one parent. No strangers, no-one added silently. Reading — set per chat, not as a blanket. For each chat you pick one of three: read along, private, or "decide per chat." Whichever you pick, the readers row at the top of every chat shows who can read it. Anyone in the chat can ask for a different setting; you approve or decline. It isn't another big-tech product, it isn't a family group chat, and it isn't yet-another walled garden that still sells your attention. It's a small, private messenger on a different deal. HOW IT'S DIFFERENT No ads. No data harvesting. No AI reading messages. No third-party SDKs, no behavioural tracking, no feed algorithm, no followers. Our business model isn't your data. The company exists to sell the app, not you. Not a big corporation. Kizoona is built by a small, independent team in Europe. We're not a division of a social network, we don't raise from investors who need your kid to scroll longer, and we answer to our users — not to a shareholder deck. Your data stays in the EU. All servers are hosted in the EU. GDPR is the floor, not the target. Nothing is "replicated" to US clouds or third parties for analytics. What we don't need, we don't store. PRIVATE BY DESIGN Every message is encrypted on the phone before it leaves, and only the people in the chat (plus the guardians the child has chosen to watch along) can decrypt it. Not even we can read them. No AI trained on your messages. No server-side content scanning. WHAT'S INSIDE • 1-to-1 chats and small group chats with friends and family. • Share photos, reply to one message, react with emoji. • Add contacts by scanning a QR code in the same room, or by typing a short 4-word phrase. • Per-chat control over which guardians read along. • Works offline until you're back online; no messages lost. Everyone in the chat sees who's reading along: at the top of every chat, the readers row shows exactly which guardians can read it. Transparent, per-chat, revisable. KIZOONA PRO — TIME MANAGEMENT Decide when each chat is available. Per-day windows (school-day afternoons, wider weekends, always-on for family), grouped by who the kid is talking to. Outside a window, outgoing messages are blocked and notifications go quiet; the next-open time is shown so the kid knows when it opens again. Kizoona Pro is €1.99 / month or €14.99 / year. Start with a 14-day free trial — cancel anytime before it ends and you won't be charged. Everything else in the app stays free; Pro only unlocks time management.
