Privacy Policy

Applies to the Exemplifi Transit Alerts email, SMS, and website notification program

Effective Date: August 20, 2026

Exemplifi Transit Alerts is a rider notification service operated by Exemplifi ("we," "us") on behalf of the transit agency whose website you subscribed on ("the Agency"). This policy explains what personal information we collect when you sign up for transit alerts, how we use it, and the choices you have. We built this service to collect as little about you as possible.

1. The alerts program

The Exemplifi Transit Alerts program sends informational service notifications — delays, detours, disruptions, planned service changes, and restored-service notices — for the routes you select or for all routes if you choose to receive everything. Messages are sent by email, SMS text message, and/or website (browser) push, based on the channels you turn on. Message frequency varies with real-time service conditions and the routes you follow. This is a transactional, informational program only; we do not send marketing or promotional messages through it.

2. What we collect

To run the alerts program we collect only what a notification needs:

  • Your contact identifiers — the email address and/or mobile phone number you enter, so we can deliver alerts.

  • Your alert preferences — the routes you select (or your choice to receive all alerts), the channels you enable, and options like quiet hours.

  • Delivery and consent records — the date, time, and method of your opt-in and confirmation, and delivery status such as bounces or opt-outs, which we keep to honor your choices and to demonstrate consent.

  • Limited technical data — for website push, a browser push token and basic device/browser type. We do not collect or require your name, mailing address, account login, password, date of birth, or payment information for this program.

3. How we use it

We use your information only to operate the alerts you asked for: to send you transit notifications for your selected routes, to honor your channel and quiet-hours preferences, to run required opt-in confirmation and unsubscribe handling, and to keep the service reliable and free of abuse. We do not use your contact information to build advertising or marketing profiles.

4. SMS & mobile data

We never share or sell your mobile information. The phone number and SMS consent you provide are used solely to deliver the transit alerts you requested. No mobile opt-in information is shared with, sold to, or rented to third parties or affiliates for their marketing or promotional purposes, and it is never passed to lead generators — at any time.

When you opt in to text alerts, you agree to receive recurring automated SMS from Exemplifi Transit Alerts at the number you provide. Message and data rates may apply. Message frequency varies. Reply STOP at any time to unsubscribe, START to resubscribe, or HELP for help Full details are in our SMS Terms & Conditions.

5. Who we share with

We share your information only with the service providers that make delivery possible, and only for that purpose:

  • Messaging providers — Twilio (SMS) and SendGrid (email) transmit alerts to your phone or inbox on our behalf, under contracts that limit them to providing that service.

  • The Agency — the transit agency whose alerts you subscribed to may see aggregate, de-identified subscription counts. It does not receive your raw contact details for marketing.

  • Legal requirements — we may disclose information if required by law or to protect the safety and integrity of the service.

We do not sell your personal information, and we do not share it with data brokers or advertisers.

6. How we protect it

We minimize and protect what we store. Your email address and phone number are encrypted at rest, and we index them for lookup using a one-way HMAC hash rather than storing them in plain text where they can be browsed. Access to subscriber data is restricted and logged. Because we deliberately avoid collecting names, passwords, and account credentials, there is far less about you at risk if anything ever goes wrong.

7. Retention & deletion

We keep your subscription and consent records for as long as you are subscribed, and for a limited period afterward to honor opt-outs and meet our legal and audit obligations. When you unsubscribe, we add your identifier to a suppression list that Exemplifi maintains as the single source of truth, so you stay unsubscribed across every channel and agency. You may request deletion of your data at any time using the contact details below.

8. Your choices

  • Change routes or channels — update your preferences any time from the manage link at the bottom of any alert.

  • Unsubscribe from SMS — reply STOP to any text.

  • Unsubscribe from email — use the unsubscribe link in any email.

  • Turn off website push — remove notification permission in your browser settings. Access or delete your data — contact us using the details below.
