Signal
Signal Foundation
Signal is an end-to-end encrypted messenger for text, voice and video calls and groups. No ads, no tracking, funded by a foundation. That same privacy is its strength — and, for younger children, exactly what calls for involvement.

Why NUNIVIA rates additionally
Official labels (USK, PEGI) primarily refer to content such as violence or language. Purchase pressure, loot boxes, addictive mechanics and manipulative UI designs (dark patterns) have only been gradually included since 2023 — older ratings do not yet fully reflect this. NUNIVIA therefore additionally evaluates real everyday risks, including UI tricks such as countdown timers, virtual currencies, FOMO events and hidden decline options.
Assessment for messenger app
Signal states that it processes minimal data and is subject to GDPR. No known proceedings against Signal in Germany. Important for parents: end-to-end encryption means that you, too, cannot read message content after the fact. Conversations stay private — here, trust and open agreements take the place of technical oversight. Signal offers no parental dashboard like WhatsApp parent-managed accounts; control relies entirely on manual contact management, device settings, and agreed-upon rules.
