SMS and WhatsApp Consent Policy
Last Updated: October 4, 2026
This policy covers the text and WhatsApp messages that HealthKey Labs, LLC, doing business as Arxova™ (“Arxova,” “we,” “us”), sends for Arxova Circle.
1.Who Receives These Messages
Arxova Circle lets a person who uses the Arxova™ app choose up to five people they want to hear their health news from. Those people are the ones who receive these messages. If you received a message from Arxova, someone you know added your phone number to their Circle.
Arxova does not use SMS or WhatsApp for marketing or promotional messages.
2.How You Opt In
When someone adds you to their Circle, Arxova sends you one invitation. It names the person who added you and includes a link to accept. You opt in by opening that link and accepting.
If you do not accept, you will not receive Circle updates. The only other message you could receive is a one-time notice if that person later removes you from their Circle.
3.SMS or WhatsApp
The channel depends on your phone number:
- United States and Canada (numbers that start with +1): messages arrive by SMS.
- All other countries: messages arrive on WhatsApp, from Arxova's WhatsApp business account.
The messages say the same thing on either channel.
4.What the Messages Say
- Invitation. The first message, with a link to accept. If you do not use Arxova, it also includes a link to download the app.
- Check-in. A short note that something in the person's recent data looks unusual and it may be a good time to check in. The person chooses how often this happens by choosing an alert level for you.
- Back to normal. A follow-up after a check-in, when the pattern has cleared.
- Good news. A milestone the person chose to share, such as reaching a weekly goal.
- Removal notice. A one-time message if the person removes you from their Circle. After it, no further messages are sent.
The messages never include the person's health records, readings, lab values, or diagnoses. If you reply to a text, your reply is shown to that person in their Arxova app.
5.Message Frequency
Message frequency varies. Arxova sends no more than three messages in any seven-day period for each Circle you belong to, across SMS and WhatsApp combined. Good-news messages are limited to one per week.
6.How to Stop Messages
By SMS: reply STOP to any message. UNSUBSCRIBE, CANCEL, END, and QUIT also work. Our messaging provider blocks further texts from Arxova to your number. Reply START if you later want to receive them again.
On WhatsApp: block the Arxova business account in WhatsApp, which stops all messages from it right away. You can also email privacy@arxova.health with your number and we will remove you from Circle messages.
On either channel, you can also ask the person who added you to remove you from their Circle.
7.Help
For help with these messages, write to privacy@arxova.health.
8.Costs
Message and data rates may apply, depending on your mobile carrier and plan. WhatsApp messages use your data connection. Arxova does not charge you for these messages.
9.Consent Is Not a Condition of Purchase
Agreeing to receive these messages is not a condition of any purchase. Arxova is free, and declining or stopping these messages does not affect anything you buy or use.
10.Your Phone Number
We use your phone number only to send Circle messages. We share it only with the providers that deliver those messages: Twilio, and for WhatsApp, Meta. We do not sell your number or share it for marketing.
11.Contact
