Privacy Policy

Last updated: March 22, 2026

TextAgent ("we", "our", "us") is committed to protecting your privacy. This Privacy Policy explains how our iOS application handles your information.

1. Core Privacy Principle

TextAgent is designed with a privacy-first architecture. All SMS classification and filtering happens entirely on your device. We never read, collect, store, or transmit the content of your text messages.

2. How SMS Filtering Works

TextAgent uses Apple's IdentityLookup framework to filter unknown sender messages. This framework is designed by Apple with strict privacy constraints:

• The Message Filter Extension runs in a sandboxed environment on your device
• It can only classify messages as Allow, Junk, or Transaction subcategories
• It cannot access your contacts, photos, or other personal data
• Message content is processed locally and never sent to our servers

3. Data We Collect

We collect minimal data necessary to provide our services:

• Account information: If you create an account, we store your email address for authentication
• Subscription status: Your subscription tier (Free, Pro, Ultra) for feature access
• Rule metadata: Filter rules you create or subscribe to (rule patterns only, never message content)
• Usage statistics: Aggregate counts (e.g., "47 messages filtered this week") — no message content
• Crash reports: Anonymous crash data to improve app stability

4. Data We Never Collect

• SMS or text message content
• Phone numbers from your messages
• Your contacts or address book
• Your location data
• Browsing history or app usage from other apps

5. On-Device Processing

TextAgent uses multiple classification layers, all running on your device:

• Rule Engine: Pattern matching against your configured filter rules
• CoreML Model: A machine learning model that runs entirely on-device
• AI Classification: When enabled, uses API calls for complex classification — only the classification result is returned, and message content is processed in-memory without persistent storage

6. Rule Marketplace

When you use the Rule Marketplace:

• We store rule definitions (patterns and categories) on our servers
• Subscription counts and ratings are aggregated anonymously
• No message content is ever shared through the marketplace

7. Third-Party Services

TextAgent may use the following third-party services:

• Apple App Store: For subscription management and payments
• LLM API providers: For AI-powered features (Pro/Ultra tiers) — subject to their respective privacy policies

8. Data Storage and Security

• Local data is stored in your device's secure storage using iOS App Groups
• Sensitive data (API keys) is stored in the iOS Keychain
• Server communications use HTTPS encryption
• We do not sell your data to third parties

9. Your Rights

You have the right to:

• Delete your account and all associated data
• Export your filter rules
• Opt out of analytics collection
• Request information about data we hold about you

10. Children's Privacy

TextAgent is not directed at children under 13. We do not knowingly collect personal information from children.

11. Changes to This Policy

We may update this Privacy Policy from time to time. We will notify you of significant changes through the app or via email.
