Privacy policy

Last updated: 08/02/2026

This app is designed to be privacy-first by default. We believe safety tools should work without collecting or centralising personal data.

This Privacy Policy explains what data the app uses, how it is handled, and what we intentionally do not collect.

1. What data we collect

We do not collect or store personal data on any server.

All data used by the app stays on your device only.

Depending on which features you enable, the app may store the following locally on your device:

  • Check-in schedule and reminder settings
  • Phone numbers of your configured contacts
  • Verification status of contacts (OTP verified or not)
  • Message templates you customise
  • Optional health information you enter manually
  • Optional activity or health data read at trigger time
  • Optional location snapshot at trigger time

App activity logs (by default, up to the last 7 days)

This data is never uploaded to any server.

2. What data we do NOT collect

We do not collect, store, or transmit:

  • Names, email addresses, or account credentials
  • Continuous or live location data
  • Background location history
  • Analytics or usage tracking
  • Advertising identifiers
  • Behavioural profiles
  • Data for marketing or resale

There are no ads, no analytics SDKs, and no third-party tracking services embedded in the app.

3. Location data and live tracking

This app cannot perform live tracking.

It does not run continuous location services, background tracking, or location streaming. There is no technical mechanism that allows real-time monitoring.

Location access is:

  • Disabled by default
  • Requested only if you explicitly enable it
  • Used only once, at the moment an SMS is triggered due to a missed check-in or safety event

After the message is sent, no further location data is accessed or shared.

Precise location is optional and only used if you explicitly enable it. Otherwise, no exact location is included.

4. Health information

Health information is optional and fully under your control.

If you choose to use the Health Summary feature:

  • Manual health entries are stored locally on your device
  • Health data is never synced to a server
  • Health data is read only at:
    • the moment an alert SMS is triggered, or
    • when you manually preview it

No health data is stored outside your device.

5. SMS messaging

All alert messages and verification messages are sent directly from your device using your mobile carrier.

The app does not route messages through any intermediate servers.

SMS costs depend on your mobile plan and the country you are in.

6. Contact verification and consent

When you add or change a contact, the app requires SMS verification using a one-time code.

Verification ensures:

  • The phone number is reachable
  • The recipient is aware they were added as a safety contact

If a contact is changed, verification must be completed again before alerts are enabled.

Verification codes are generated on your device and stored only as encrypted hashes.

7. Data storage and security

All app data is stored locally on your device.

  • Activity logs are kept for a limited time by default (up to 7 days)
  • You can clear logs at any time

Even though we do not collect personal data, the local database is encrypted to protect sensitive information stored on the device.

8. Children and dependents

This app is intended to be configured by adults.

If you configure the app for a child or dependent, you are responsible for managing their contact details and ensuring consent from guardians where required.

9. Not a replacement for human or emergency care

This app is not a substitute for:

  • In-person check-ins
  • Regular communication
  • Medical care
  • Emergency services

If you believe someone is in immediate danger, always contact local emergency services.

10. Changes to this policy

If this Privacy Policy changes, the updated version will be made available within the app.

Because the app does not collect server-side data, changes to this policy do not affect previously stored information.
