SMS & messaging terms

Messages are sent from a verified US toll-free number, on behalf of chron.dog (a solo-developer project, currently in private beta). The first message you receive from Chrono will identify the host who invited you and Chrono himself.

Recipients are added to events only by hosts who confirm they have your permission. Hosts must indicate that consent before chron.dog will text you. We do not purchase, rent, or scrape phone-number lists.

You may opt out at any time by replying any of these keywords to a message from Chrono:

• STOP, UNSUBSCRIBE, CANCEL, QUIT, or END

Opt-outs are processed immediately. We'll stop messaging you across all future events. To resume receiving messages, reply START or SUBSCRIBE.

For help, reply HELP or email hello@chron.dog.

Frequency varies by your event activity. A typical event sends one invite, one availability prompt, one or two proposals, and one confirmation per recipient — usually under five messages over a few days. Hosts may receive additional messages summarizing replies.

chron.dog does not charge recipients for messages. Standard message and data rates from your carrier may apply.

We collect only the information needed to coordinate scheduling: name (as provided by the host), phone number, the body of replies, and your inferred time zone. We do not sell or share recipient data with third parties.

Phone numbers and message bodies are retained only for the duration of the event and a short audit window, then automatically purged. To request immediate deletion, email hello@chron.dog.

We deliver messages through Microsoft Azure Communication Services. Carriers may filter, delay, or block messages at their discretion; chron.dog cannot guarantee delivery.
