Updated October 23, 2026. Breakthrough Calendar is operated by Kick Research LLC. The app helps organize events and coordinate schedules. Review event details and alarm settings before saving. Calendar syncing, networks, operating-system scheduling and SMS delivery can be delayed; do not use this beta as your only reminder for safety-critical obligations.
Send invitations only to people who expect to hear from you. Respect declines and blocks. Do not use the app for spam, harassment, impersonation or unsolicited marketing. Share only information you have permission to disclose. You can leave groups, remove contacts and stop sharing.
You may separately opt into Breakthrough Calendar contact/group invitation notifications and early-event reminders after verifying your phone. Verification alone does not enroll you. Consent is not required to use the app or create an account. Frequency varies; early-event reminders are limited to one per day. Message and data rates may apply. Reply STOP to opt out and receive confirmation; reply HELP for assistance or email help@breakthroughcal.com. Carriers are not liable for delayed or undelivered messages. Change your verified number when your number changes. SMS availability depends on your country and carrier.
To enable or disable notifications, open Profile → Contacts & Groups → Sharing & reminders. Automated messages are sent only after opt-in. Personal invitations to others may use your own Messages app.
