Effective Date: December 2, 2025
Last Updated: December 2, 2025
Introduction
TextSynth LLC ("TextSynth," "we," "us," or "our") provides an SMS-based AI assistant service that allows you to interact with artificial intelligence agents through text messaging. This Privacy Policy explains how we collect, use, and protect your information.
By using TextSynth, you agree to this Privacy Policy.** If you don't agree, please don't use our service.
What TextSynth Does
TextSynth is a conversational AI service delivered via SMS. You text questions or commands to our phone number, and our AI agents respond with answers, information, or assistance. The service maintains conversation context across multiple messages to provide helpful, coherent responses.
Information We Collect
What You Give Us Directly
Phone Number
We need your mobile phone number to send and receive text messages. This is required for the service to work.

- Improve our AI models
- Troubleshoot issues

If you register on our website, we collect:

How We Use Your Information
To Provide the Service
AI Response Generation
Your messages are sent to AI language models (like Claude, GPT, or Gemini) to generate responses. The AI reads your message history to understand context and provide better answers.
Conversation Memory
We store recent messages (default: 90 days) so the AI remembers what you talked about earlier in the conversation.
To Operate Our Business
Service Delivery
We use SMS delivery services to route messages between you and our AI agents. Your phone number and message content are shared with these SMS providers to make delivery possible.
To Improve Our AI
Model Training
We may use anonymized conversations to train and improve our AI models. Before using your data for training, we:
- Remove your phone number
- Remove personally identifiable information
- Aggregate data with thousands of other conversations
You can opt out of this by emailing privacy@textsynth.io.
Customer Support
If you contact us for help, we use your information to respond to your questions and resolve issues.|
Billing
If you have a paid subscription, we use payment information to process charges. We use third-party payment processors (like Stripe) who securely handle your credit card details.
Analytics
We analyze usage patterns to understand:
- What features people use most
- Where people get stuck or confused
- How to make the service better
Security & Fraud Prevention
We monitor for suspicious activity like:
