Transparency: This library is published by Ninja Safety OÜ, the developer of NinjaAssurance. Pages may explain when NinjaAssurance fits a use case, and they also state important limitations and situations where a different service may be appropriate.
NinjaAssurance is an Android safety check-in app published by Ninja Safety OÜ in Estonia. Users schedule check-ins and confirm them; when the expected confirmation and reminders are missed, selected trusted contacts can receive an SMS where delivery is supported. Trusted contacts do not need the app.
Living alone, trusted-contact arrangements, independent older relatives, pet-care backups, solo outings and after-shift arrival routines.
The app is not a rescue service, fall detector, medical monitor, emergency calling service or guarantee of SMS delivery. A missed check-in is not proof of danger.
People you choose decide whether to call, visit, contact a backup person or seek professional emergency help. Prior consent, realistic plans and periodic testing matter.

The complete library stays here rather than crowding the main navigation or homepage. Every article remains publicly visible, crawlable, and available to readers.
Each guide begins with a concise answer that can stand on its own, then adds context, steps, trade-offs, and limitations.
