SMS Terms

Last updated: August 7, 2026

Version: 1.0

These SMS Terms govern the Stowlog Account Verification text messaging program operated by Estudio Cactus Media S.L., trading as Stowlog. They apply to every person who provides a mobile number to Stowlog and consents to receive verification messages at that number. They are written to be read on their own: everything you need to know about the program is set out on this page.

Program name and operator

The name of this text messaging program is Stowlog Account Verification. It is operated by Estudio Cactus Media S.L., trading as Stowlog, a company incorporated in Spain with tax identification number (CIF) B12962957 and registered address at Rda. Circunvalación 188, 12003, Castellón de la Plana, Spain.

Messages are sent to recipients in the United States and internationally. Messages sent to United States numbers originate from a Stowlog 10DLC long code registered to Estudio Cactus Media S.L. Messages sent to numbers outside the United States may originate from a long code or from an alphanumeric sender identified as Stowlog.

What this program sends

Stowlog Account Verification sends one type of message and one type only: a one-time security code used to verify your identity when you sign in to a Stowlog account, when you register a mobile number, or when you carry out an action that requires you to authenticate again. Each message contains the Stowlog name, a numeric code, the time at which the code expires, and a reminder never to share the code with anyone.

This program sends no other kind of message. Stowlog will never use the mobile number you provide for this program to send you:

• marketing, promotional, advertising or sales messages of any kind;
• newsletters, product announcements, offers, surveys or event invitations;
• operational or transactional notifications about facility visits, bookings, deliveries, documents or any other activity on the Stowlog platform;
• messages on behalf of a facility, a customer of Stowlog, or any other third party; or
• automated, scheduled or recurring messages that you did not trigger yourself.

A verification message is only ever sent in direct response to an action you have taken. If you do not attempt to sign in or to verify your identity, you receive no messages.

How you give consent

Consent is given inside the Stowlog App (mobile or web) when you create your account, or later when you add or change a mobile number in your account settings. On the screen where you enter your mobile number, a separate consent control appears immediately next to a plain-language summary of this program. That control is not selected by default, it is not combined with acceptance of our Terms and Conditions or of our Privacy Policy, and it has to be selected deliberately by you.

Consent to receive text messages is optional and is not a condition of registering for, purchasing or using Stowlog. You can create and use a Stowlog account without giving it. If you decline, or if you opt out later, identity verification is carried out using a one-time code sent to the email address on your account, and your access to Stowlog is unaffected.

When you consent, Stowlog records the date and time of your consent, the mobile number you provided, the IP address from which the consent was submitted, the account it relates to, and the wording of the consent screen shown to you at that moment. That record is retained for as long as the number remains on the account, and afterwards for the period needed to evidence the consent.

Consent is given to Estudio Cactus Media S.L. for the Stowlog Account Verification program only. It is not transferable, assignable or shareable, and it is never sold, rented or passed to any other sender, brand or affiliate.

The consent wording shown in the Stowlog App

The opt-in screen sits inside an account registration flow, so the wording is reproduced here in full. The text below is what is displayed immediately next to the consent control:

"Receive verification codes by SMS. By checking this box you agree to receive one-time security codes from Stowlog at the mobile number above. This is optional and is not required to use Stowlog. Message frequency varies. Message and data rates may apply. Reply STOP to cancel, HELP for help. See our SMS Terms and our Privacy Policy."

Message frequency

Message frequency varies. Messages are sent only when you request one, as a rule one message per sign-in or verification attempt. If you never sign in, you receive no messages. Stowlog sends no recurring or scheduled messages under this program.

Cost

Standard message and data rates may apply. Stowlog does not charge you for these messages, but your mobile carrier may charge you for receiving them under your plan. Check with your carrier if you are unsure. Rates applying to messages received while roaming, or on numbers outside the United States, are set by your carrier and not by Stowlog.

How to stop receiving messages

To stop receiving messages, reply STOP at any time. Send the reply to the number the message came from.

The following keywords are honoured, in upper or lower case, and each stops every message sent under this program: STOP, STOPALL, UNSUBSCRIBE, CANCEL, END and QUIT. REVOKE and OPTOUT are honoured as well. Minor differences in spelling or spacing do not invalidate an opt-out request.

After an opt-out request you receive one final confirmation message, and nothing after it. That confirmation reads: "Stowlog: you have been unsubscribed from Stowlog verification messages and will receive no further texts. Reply START to resubscribe. Help: support@stowlog.com".

Opting out does not close your Stowlog account and does not stop you from using Stowlog. Identity verification switches to a one-time code sent to the email address on your account.

To start receiving verification codes again, reply START or UNSTOP to the same number, or re-enable SMS verification in your Stowlog account settings.

You can also opt out at any time without sending a message, by turning off SMS verification in your Stowlog account settings or by writing to support@stowlog.com. If a message reached you from an alphanumeric sender rather than from a phone number, a reply cannot be delivered — use either of these two routes instead, and we will action it in exactly the same way.

How to get help

For assistance, reply HELP to the number from which you received the message, or contact us at support@stowlog.com.

Replying HELP returns the following message: "Stowlog Account Verification: one-time security codes for your account. Msg&data rates may apply. Reply STOP to cancel. Help: support@stowlog.com".

You can also reach us by email at support@stowlog.com, by telephone on +34 964 23 84 12, or by post at Estudio Cactus Media S.L., Rda. Circunvalación 188, 12003, Castellón de la Plana, Spain.

Carriers and delivery

Carriers are not liable for delayed or undelivered messages.

Delivery depends on your mobile carrier, your device and your network coverage, none of which Stowlog controls. Stowlog cannot guarantee that a message will arrive, or that it will arrive within any particular time. If a verification code does not reach you, use the alternative verification method offered in the Stowlog App rather than requesting repeated codes.

This program is supported on the major carriers in the United States, and on carriers elsewhere where message delivery is available. Carrier support may change without notice, and carriers are not liable for this program.

Eligibility

You may only give consent for a mobile number that you own or are authorised to use. You must be at least 18 years old, or the age of majority where you live, in order to consent. If the number is reassigned to another person, or you stop using it, remove it from your Stowlog account or reply STOP so that no further messages are sent to it.

Privacy

We do not share, sell, or provide your mobile phone number or messaging consent data to third parties or affiliates for marketing or promotional purposes. Text messaging originator opt-in data and consent are not shared with any third party, except the communications provider that transmits the messages on our behalf and where disclosure is required by law.

Your mobile number is disclosed only to processors acting on our documented instructions — our hosting and database providers, and Twilio Inc. as our SMS delivery provider — and to your mobile network operator, which necessarily processes the message in order to deliver it. Twilio processes the number and the message content solely in order to deliver the verification code to your device, under a written data processing agreement. Twilio may not use them for its own purposes and may not sell or rent them; it may engage its own sub-processors and route the message through mobile network operators, solely in order to deliver it and under equivalent contractual obligations.

For this program Stowlog collects and uses your mobile number, your mobile carrier and country, the delivery status of each message, and the record of your consent and of any opt-out. That data is used to send and troubleshoot verification codes, to protect your account, and to evidence your consent. It is not used for profiling, advertising or any other commercial purpose.

How Stowlog handles personal data more generally, including the legal basis, the retention periods and your rights under the GDPR, is set out in our Privacy Policy and in particular in its section headed "SMS and Text Message Communications". The Privacy Policy is available at https://www.stowlog.com/legal/privacy.

Sample messages

Messages sent under this program take the following form:

• Stowlog: your verification code is 123456. It expires in 10 minutes. Never share this code. Reply HELP for help, STOP to opt out.
• Stowlog: 654321 is your Stowlog verification code. It expires in 10 minutes. Stowlog will never ask you for this code. Reply STOP to opt out.

Verification messages never contain a link, never ask you to reply with your code, and never ask for a password, a card number or any other personal detail. If you receive a message that claims to come from Stowlog and does any of those things, do not act on it and report it to support@stowlog.com.

Changes to these terms

Stowlog may update these SMS Terms. The version in force is the one published on this page, and the date at the top of the page states when it was last changed. Material changes to the program are notified through the Stowlog App before they take effect. Continuing to use SMS verification after a change takes effect means you accept the updated terms.

Relationship with our other terms

These SMS Terms are self-contained and govern the text messaging program only. They do not replace the Stowlog Terms and Conditions or the terms of use applying to the Stowlog App, and nothing in those documents makes consent to receive text messages a requirement.
