About This Program
These SMS Terms apply to "Techimprovement sign-in codes", the text message program of Tech Improvement Inc. ("Techimprovement", "we", "us" or "our"), Philadelphia, Pennsylvania 19125, United States, which runs the website and online store at techimprovement.net. The messages are sent by Tech Improvement Inc. These SMS Terms are part of our Terms and Conditions.
What We Send
We send one-time verification codes by text message for your Techimprovement account:
- a code when you sign in, if you turned on text message codes for your sign-in; and
- a code to confirm your mobile number when you turn on text message codes or change the number in your sign-in security settings.
A message looks like this: "482913 is your Techimprovement verification code. It expires in 10 minutes. Reply STOP to opt out, HELP for help." We do not send marketing or promotional messages in this program.
How You Opt In
Text message codes are optional. You opt in by entering your mobile phone number and ticking the consent box, which is never ticked in advance:
- in My Account › Two-Factor Authentication › Text message (SMS); we then send a code to confirm the number; or
- optionally, in the "Sign-in protection (optional)" section of the Create an Account page; we send nothing until you confirm the number with a code in your account.
You must be the account holder or an authorized user of the mobile number. Consent is not a condition of purchase: you can create an account, sign in and buy without text messages, for example with an authenticator app. The consent box looks like this:
Mobile phone number with the country code:
+1 555 123 4567
I agree to receive one-time verification codes by text message from Techimprovement at this number, sent when I sign in or change my sign-in security settings. Message frequency varies with your sign-ins. Message and data rates may apply. Reply STOP to opt out, HELP for help. Consent is not a condition of purchase. See our SMS Terms and Privacy Policy.

Message Frequency
Message frequency varies with your sign-ins: we send one message each time you sign in with a text message code, ask for a new code, or confirm a mobile number for your sign-in security. We do not send messages on a schedule.
Costs
Message and data rates may apply, depending on your mobile plan. We do not charge for these messages.
How to Opt Out
Reply STOP to any of our messages to stop receiving them. After you send STOP, you receive one message confirming that you have opted out, and no further messages from this program. You can also turn off text messages at any time in My Account › Two-Factor Authentication.
After opting out, sign in with your authenticator app or a backup code. To receive codes by text message again, reply START to our number. If you turned off text messages in your account, turn them on again there.
Help
Reply HELP to any of our messages for help, or email info@techimprovement.net. You can also reach us through our contact page.
Carriers and Delivery
Supported carriers may change. Carriers are not liable for delayed or undelivered messages. If a code does not arrive, ask for a new code, or use your authenticator app or a backup code.
Privacy
Our Privacy Policy explains how we handle your information, including your mobile number and the record of your consent. We do not sell, rent or share your mobile number or your text message consent with third parties or affiliates for their marketing or promotional purposes. We share your mobile number only with the SMS provider that delivers the codes on our behalf (Twilio), and only for that purpose.
Changes to These Terms
We may update these SMS Terms. We will post the new version on this page and update the "Last updated" date.
