Privacy policy
Last updated November 8, 2026
RegistrantReminders ("we") provides reminder emails and calendar invites for Zoom meeting registrants on behalf of meeting hosts ("customers"). This policy explains what we collect and why.
Data we process
Customers (hosts)
- Account details: name, email, password hash, timezone, branding settings.
- Zoom profile: Zoom user id, account id, email, display name, and OAuth tokens (encrypted at rest).
- Billing: handled by Stripe. We store your Stripe customer id and subscription status, never card numbers.
Registrants
When you connect Zoom we receive, for each meeting with registration, the registrant's name, email address, registration time, chosen occurrences and personal join link. We process this as your service provider, solely to send the invites and reminders you configured. Join links are encrypted at rest and never written to logs.
Email delivery
We record what was sent to whom, when, and the delivery outcome (delivered, bounced, complaint, unsubscribed). Addresses that hard-bounce or complain are added to a per-customer suppression list so they are not emailed again.
How we use data
- To send calendar invites, updates, cancellations and reminders for your meetings.
- To operate, secure and support the service, including fraud and abuse prevention.
- To bill you. We do not sell data or use registrant data for advertising.
Sub-processors
Zoom (source of meeting and registrant data), Postmark (email delivery), Stripe (payments), Laravel Forge / our hosting provider (infrastructure), Cloudflare (DNS and edge), Google Analytics on the marketing site only.
Retention and deletion
Registrant data is kept while the related meeting is upcoming and for 90 days afterwards for your activity log. If you remove the app from Zoom, all Zoom-derived data is purged within 3 days. Deleting your account removes everything immediately.
Registrant rights
Every reminder includes an unsubscribe link that stops reminders instantly. Registrants may contact the meeting host, who controls the data, or email us at support@registrantreminders.com and we will assist.
Security
TLS in transit; AES-256 encryption at rest for tokens and join links; webhook signature verification; least-privilege, read-only Zoom scopes; admin access limited to an allowlist.
