How it works & privacy
Your parent’s everyday conversations are never sent to your family or to us. Here is exactly what stays on the phone and what is sent.
When urgent words are spoken
- The kinguard Senior app picks out speech from surrounding sound and turns it into text on the phone.
- It checks that the voice is your parent’s and that it contains an urgent word your family chose.
- If it’s urgent, kinguard Guardian gets an alert within seconds: the words, the time, 15 seconds of audio, and a call button.
- Your parent sees a large button: “We told your family. Press if you’re OK.” Pressing it sends an “I’m OK” update.
- You call, see how to reach emergency services, and record what happened.
What stays on your parent’s phone
- Everyday sound – only the last 15 seconds are kept in memory, constantly overwritten, never saved
- Text of everyday speech – thrown away right after the check
- Voiceprint (voice setup data) – encrypted on the phone and deleted right away when your parent disconnects, withdraws consent, or uninstalls the app
None of this is sent to kinguard’s servers. Our staff can’t see it either.
What is sent, and how long it’s kept
Only the minimum needed to show your family an alert is uploaded.
| Data | When | Kept for |
|---|---|---|
| Alert record (words, level, time, outcome) | When an alert happens | 90 days |
| Audio clip (15 seconds around the alert) | Urgent alerts (your family can turn this off) | 30 days |
| 5-minute text record after an urgent alert | 5 minutes after an urgent alert | 30 days |
| Automatic recording (up to 3 minutes) | Only if your parent separately agreed | 30 days |
| Phone status (battery, last activity) | Periodically | Latest value only |
| Family account and purchase records | At sign-up and purchase | Until you delete your account · purchase records as required by law |
After the retention period, data disappears from the app right away; full deletion from storage can take a few more days. Periods may change after legal review.
What we don’t do
- There is no way for family to turn on your parent’s microphone and listen at any time
- No ads, and we don’t sell personal information
- We don’t score, profile, or diagnose anyone from their voice
- It can’t be installed secretly – nothing starts without your parent’s own consent
Your parent’s own consent
kinguard Senior explains what it does with voice guidance, and your parent must agree on their own phone. Voice setup and automatic recording each need separate consent.
Your parent can pause for an hour, disconnect, or withdraw consent at any time. A notification at the top of the phone always shows that detection is on.
Where data is stored
Your family’s data is stored only in the region where your parent lives: US data in a US region, EU data in an EU region, Korean data in Seoul. It isn’t moved between regions.
Sign-in and push notifications use Google Firebase.
Limits you should know
- Detection pauses during phone calls, because the call uses the microphone
- Alerts can’t be sent when the phone is far away, off, or offline
- Phone settings such as battery optimization can stop detection. If that happens, you get a “Device issue” alert
- kinguard can mishear or miss words
