CAJA305 is a point-of-sale and inventory system for small shops, used from a browser at caja305.com. This page describes every text message the system sends, who receives it, how that person agreed to receive it, and how they stop it.

1 Who sends these messages

CAJA305 is operated by ROIZ Growth Partners LLC, Miami, Florida, United States. Each shop using CAJA305 is a separate business. Messages are sent by the shop to that shop's own customers and vendors, through CAJA305.

Contact: contact@roizpartners.com.

2 What we send, and to whom

• Sign-in verification codes — to the staff of a shop, at the number their own shop recorded for them. Sent only when that person is signing in. One message per sign-in attempt.
• Purchase receipts — to a customer who asked for the receipt of the purchase they just made, at the till, giving their number for it. One message per purchase. Off unless the shop turns it on.
• Purchase orders — to a vendor of the shop, at the number the shop has on file for that vendor, containing the order the shop is placing. Sent when the shop sends an order.
• Offers and reminders — to customers of the shop who joined its loyalty programme and ticked the box agreeing to receive them. Typically no more than four messages a month.

Verification codes, receipts and purchase orders are sent because the person asked for that specific thing. Offers and reminders are the only ones that are marketing, and they require the separate consent described below.

3 How someone agrees to receive messages

A customer joins a shop's loyalty programme from a form on that shop's own page at <shop>.caja305.com/unirse/, or by giving their details at the till. The form asks for the mobile number and shows a separate, unticked box with this text:

The box is optional: a customer can join the programme without ticking it, and then receives no marketing messages. When it is ticked, CAJA305 records the date and time of the consent against that customer, and that record is what authorises any later message. A customer who never ticked it is never sent one.

Staff numbers for verification codes, and vendor numbers for purchase orders, are entered by the shop itself, for that purpose.

4 How to stop them

Reply STOP to any message. The number is unsubscribed immediately and receives no further marketing messages. CAJA305 records the opt-out and blocks the number at the point of sending, so it cannot be re-added by an import or by a member of staff.

Reply HELP for help, or write to contact@roizpartners.com. A customer can also ask the shop directly to remove their number.

Message and data rates may apply. Message frequency varies by shop and by the kind of message, as described in section 2.

5 What happens to the number

We do not sell mobile numbers, and we do not share consent to receive text messages with anyone. No mobile opt-in data and no consent record is shared with third parties or affiliates for their own marketing.

Numbers are held to run the shop's own programme and are passed only to the carrier that delivers the message. The full details are in our Privacy Policy, and the rules for the shops that use the system are in our Terms of Service.

6 Carriers

Carriers are not liable for delayed or undelivered messages.
