Terms of use

Last updated 15 October 2026

These terms cover the Guardian Star app, its server, and Guardian Star Plus's texts and calls. The app is also licensed to you under Apple's standard license agreement. Using Guardian Star means you agree to them.

Not an emergency service

Guardian Star is a daily check-in. It can't detect falls or emergencies, doesn't contact emergency services, and depends on phones, networks and services that can fail or be late. Don't rely on it alone for anyone's safety. If someone may be in danger, call 911.

Guardian Star Plus

Plus is an auto-renewing subscription, bought in the App Store and paid with your Apple Account. It renews unless you turn it off at least a day before the end of the period, in your iPhone's Settings, your name, Subscriptions. Refunds are handled by Apple.

Guardian Star check-in texts and calls

• What they are: with Guardian Star Plus, Guardian Star texts the family of someone who checks in daily: if they miss a check-in, as each step of the alert goes out (with an automated phone call for the urgent steps), when someone is on it or it's resolved, and, if you want it, a short text once a day when all is well.
• Joining: nobody gets them without asking. You join by texting JOIN and the 4-digit code from your invite to Guardian Star's number from your own phone, after someone who uses Guardian Star invited you. Joining isn't a condition of buying anything.
• How often: message frequency varies: usually one text a day, more if a check-in is missed.
• Cost: message and data rates may apply.
• Stopping: reply STOP to stop all texts and calls, or DAILY to stop just the daily text. Reply START to start again, and HELP for help.
• Carriers are not liable for delayed or undelivered messages.
• Questions: xwisniewski2@icloud.com. How we handle numbers: privacy policy. More about the texts: Guardian Star's texts.

Guardian Star check-in emails

• What they are: with Guardian Star Plus, Guardian Star can also email the family of someone who checks in daily: the same steps and notes as the texts, and, if you want it, a short email once a day when all is well.
• Joining: Guardian Star emails an address once to ask, after someone who uses Guardian Star added it, and sends nothing more unless its owner says yes on the page that email links to.
• Stopping: every email has a link that stops all of Guardian Star's emails to that address, invites included; the daily email also has one that stops just the daily ones. More: Guardian Star's emails.

Fair use

Only add people who know you're adding them, and only numbers and email addresses that are theirs. Don't use Guardian Star to bother anyone or for anything unlawful.

No warranty

Guardian Star is provided as it is. As far as the law allows, we aren't liable for any harm from using it, or from a check-in, alert, text or call that didn't arrive or arrived late.
