E-commerce & Storefront Information

• Your Google account email address
• Your name and (if available) profile picture
• A stable, anonymized Google account identifier (the “sub” claim) used only to recognize you on return visits

We do not request access to your Google contacts, calendar, Drive files, Gmail messages, or any other Google service. We use this information solely to create or sign you into your storefront account. You can revoke our access at any time at myaccount.google.com/permissions. This use complies with the Google API Services User Data Policy, including the Limited Use requirements.

• To process payments and manage your subscription
• To send service-related notifications (email, SMS, or Telegram)
• To respond to your inquiries and provide customer support
• To comply with legal obligations
• To detect, prevent, and address technical issues or fraud

We do not use Google account data for advertising, analytics profiling, or training AI/ML models, and we do not transfer it to third parties for those purposes.

4. How We Share Your Information

We do not sell your personal information. We may share your information with:

• Payment processors (Stripe) to process transactions securely
• Service providers who assist in operating our platform (e.g., hosting, email delivery)
• Legal authorities when required by law or to protect our rights

5. SMS / Text Messaging Data

When you opt in to receive SMS messages from Sigma Tech Communications (either directly or through one of our Business Clients using our platform), we collect and store the following:

• The consent record (timestamp, IP address, URL of the opt-in form, and the exact text you agreed to)
• A log of SMS messages sent to and received from your number
• Your opt-out status and keyword history (STOP, HELP, START, etc.)

This data is used exclusively to (a) deliver the SMS messages you consented to, (b) honor opt-out requests, and (c) provide legally required records of consent. You may opt out at any time by replying STOP to any message or by contacting us directly. See our SMS Terms & Conditions for details.

7. Data Security

We implement industry-standard security measures to protect your information, including SSL/TLS encryption, secure payment processing via Stripe, and access controls on our servers. However, no method of electronic transmission or storage is 100% secure.
