How text message opt-in works

Current status

Our 10DLC brand and campaign are approved and active. SMS is available only to users who have explicitly opted in. Inbound STOP requests are still honored immediately.

The opt-in steps

1. 1. Open the public sign-up form

   Go to https://sayimin.com/auth?mode=signup&intent=player directly, or tap "Create a free profile" and select "Continue as Player". No existing account or login is required.

2. 2. Sign-up asks for contact details

   The form visibly asks for Your full name, Phone, Email and Password.

3. 3. Separate, unchecked email and SMS choices

   Directly beneath the contact fields, under the heading "How should we reach you?", email and SMS are two separate checkboxes. Both start unchecked. The SMS box must be selected manually by the person and shows the exact disclosure quoted below, with links to our Privacy Policy and Terms of Service.

4. 4. Phone number alone is not consent

   Entering a phone number does not opt anyone into texts. Sign-up completes normally with the SMS box unchecked, and leaving it unchecked has no effect on joining a team, subbing, organizing or payment.

5. 5. We store the consent record

   Only when the SMS box is ticked do we save the consent flag, the timestamp, the screen it came from and the exact text displayed, plus an immutable audit row. Unticking it later records an opt-out the same way.

6. 6. Changing the choice later

   Existing users can change the same SMS preference, with the same checkbox and wording, on their Profile or Settings page. People who sign up with Google review the same unchecked choice when they finish their profile.

7. 7. Messages we then send

   Only transactional team messages: a game invitation or reminder with the date, time and place; a request to RSVP; and a substitute invitation with the spot details. No marketing, no promotions, no third-party content.

8. 8. Opting out and getting help

   Replying STOP to any message immediately ends all texts and is logged; replying HELP returns contact information and a link to this page. Users can also switch texts off in Settings at any time.

Consent language

“I agree to receive text messages from I'm In about my team's schedule, game RSVPs and substitute invitations. Consent is optional and is not required to create an account or use I'm In. Message frequency varies. Message and data rates may apply. Reply STOP to opt out, HELP for help.”

Sample messages

• I'm In: Thursday Night Volley plays Thu Oct 2, 7:30 PM at Lakeside Courts. Are you in? Reply YES or NO. Msg&data rates may apply. Reply STOP to opt out, HELP for help.
• I'm In: Westside Hoops needs 1 sub Sat Oct 4, 10:00 AM, Grant Park. Can you play? Reply YES or NO. Msg&data rates may apply. Reply STOP to opt out, HELP for help.
• I'm In: Got it — you're in for Thu Oct 2, 7:30 PM. Reply STOP to opt out, HELP for help.

Message frequency and cost

Frequency varies with a person's team schedule — typically a few messages per week during a season. Message and data rates may apply. Carriers are not liable for delayed or undelivered messages.

Data handling

Phone numbers and SMS consent are never sold, and are not shared with third parties or affiliates for their marketing. Details are in our Privacy Policy and Terms of Service .
