Privacy Policy
Last Updated: July 28, 2026
ChatMend ("we," "our," or "us") operates the ChatMend application and website (the "Service"). This Privacy Policy explains how we collect, use, and protect your information when you use our Service.
By using the Service, you agree to the collection and use of information in accordance with this policy.
1. Information We Access
Imported Conversation Files (Mobile App) — You can import conversations into the mobile app from files you provide: SMS Backup & Restore XML exports, ChatMend JSON/XML exports, WhatsApp chat exports, or pasted text. Imported conversations are stored locally on your device; when you run an analysis, the conversation you selected is transmitted for processing as described in Section 2.
SMS Messages — Two of our apps can read the SMS/MMS messages stored on your device, each only with your permission. ChatMend SMS Backup — a separate app on Google Play whose core purpose is backing up and restoring your text messages — reads your messages so you can export them to a file or restore them; this happens entirely on your device and is never transmitted to our servers or to any AI provider. The full-featured analysis app distributed directly from chatmend.com (not the Google Play analysis app) can read your SMS so you can pick a conversation to analyze; only the conversation you choose is transmitted for processing as described in Section 2. The ChatMend analysis app on Google Play does not request SMS permissions — it works only with conversation files you import.
Uploaded Conversations (Web) — On the web version, you may paste or upload conversation text for analysis. This data is sent to our cloud servers for AI processing and is not retained after the analysis response is returned.
Contacts — On the apps that read SMS (see above), and with your permission, the app can use your contacts to show names next to message threads. This is optional; the app works without it. We do not upload your full contacts list or phone numbers. Any participant names or labels you assign are included with an analysis request so the AI can refer to each person. The ChatMend analysis app on Google Play does not request contacts permissions.
Anonymous Identifier (Mobile App) — The mobile app signs in to our backend with an anonymous, randomly generated identifier (Firebase Anonymous Authentication). It is used only to secure analysis requests and apply fair-use rate limits. It is not linked to your name, email address, or phone number.
Account Information — When you create an account, we collect your email address and authentication credentials. This is used to identify your account and sync your analysis history across devices.
Early-Access Signups (Web) — If you join our early-access list, we store the email address you submit so we can contact you about your access. We do not sell this address or use it for unrelated marketing.
Device Information — We may collect non-personal device information such as device type, operating system version, and app version for the purpose of improving performance and diagnosing technical issues.
2. How Your Data Is Processed
On-Device Preparation (Mobile) — On the mobile app, reading, filtering, and selecting conversations happens locally on your device. Only the conversation you choose to analyze leaves your phone.
Cloud AI Analysis — To generate relationship insights, the excerpts of conversation text you select or provide, together with the participant labels and relationship type you assign, are transmitted to our secure cloud backend (Google Firebase Cloud Functions, hosted in the United States) and to our AI provider, OpenAI, which performs the analysis. This data:
- Is transmitted using industry-standard encryption (HTTPS/TLS)
- Is processed in real time to produce your results
- Is not stored permanently on our servers and is not written to our server logs
- Is processed by OpenAI under its API terms; OpenAI does not use data submitted through its API to train its models
We do not transmit your phone numbers or your full contacts list.
Analysis Results — When you use an account, your analysis results (attachment styles, health scores, insights) are stored in your account via Firebase Firestore so they sync across your devices. You can delete this data at any time from your account settings.
3. Your Responsibility & Consent
You should only analyze conversations that you are a participant in, or that you otherwise have the legal right to analyze. Other participants in a conversation have not separately agreed to this Privacy Policy, and you are responsible for ensuring your use complies with applicable laws.
4. Information We Do Not Collect
- We do not collect, store, or sell your personal SMS messages
- We do not collect phone numbers or contact information
- We do not use advertising trackers or sell your data to third parties
- We do not share your data with data brokers or marketing companies
5. Data Retention
Analysis results saved to an account are retained until you choose to delete them. Conversation excerpts sent for analysis are processed transiently and are not retained on our servers after the analysis response is returned.
6. Data Security
We implement appropriate technical and organizational measures to protect your data, including:
- On-device processing to minimize data transmission
- HTTPS/TLS encryption for all cloud communications
- No permanent server-side storage of user conversation data
- Secure cloud infrastructure provided by Google Firebase
7. Not Professional Advice
ChatMend provides automated, AI-generated insights for educational and self-reflection purposes only. It is not a medical, psychological, or mental-health service, and its output is not a diagnosis or professional advice. AI analysis can be wrong and cannot see the full context of your relationship.
8. Children's Privacy
The Service is not intended for use by anyone under the age of 18. We do not knowingly collect personal information from children. If you believe a child has used the Service, please contact us and we will take steps to remove any associated data.
9. Third-Party Services
The Service relies on the following third-party services, each of which processes data under its own privacy policy:
- OpenAI (AI processing of conversation excerpts) — OpenAI Privacy Policy
- Google Firebase (cloud functions, authentication, hosting) — Google Privacy Policy
- Expo (mobile app development framework) — Expo Privacy Policy
10. Your Rights
You have the right to:
- Delete your analysis history at any time
- Delete your account and all associated data
- Contact us with questions about your data
We do not sell or share personal information as defined under the California Consumer Privacy Act (CCPA). California residents may exercise the rights described above by contacting us at the address below.
