3. AI Processing
Hadithi uses third-party AI models (including models by Anthropic and Google) to power core features. Understanding how your data is processed by AI is important:
What is sent to AI providers
- Voice analysis: Your writing samples are sent to the AI provider to generate a voice profile (tone, style, patterns).
- Topic research: Your topic prompts and follow-up questions are sent to generate research panels (quotes, data, angles, insights).
- Draft generation: Your topic, research context, voice profile, and editorial preferences are sent to generate drafts.
- Rewrites: Selected text and rewrite instructions are sent for content refinement.
How AI providers handle your data
- We select AI providers that commit to not using customer inputs to train their models under their standard API terms.
- AI providers may temporarily process your data in memory to generate responses, but do not retain your inputs beyond what is needed for the request.
- We maintain data processing agreements with our AI providers where available.
- AI providers' own privacy policies and terms govern their processing. We encourage you to review them.
Our commitments
- We do not use your content to train Hadithi's own models or any third-party models.
- We do not share your content with AI providers for any purpose other than providing the specific Service feature you requested.
- We send only the minimum data necessary for each AI request.
4. Data Sharing and Disclosure
We do not sell, rent, or trade your personal information. We share data only in the following circumstances:
Service providers
We use third-party companies and individuals to perform services on our behalf ("Service Providers"). These include:
- AI processing: Anthropic, Google (for content generation and analysis)
- Hosting and infrastructure: Cloud hosting providers for application and database hosting
- Email delivery: Transactional email services for account notifications
- Payment processing: Payment gateway providers (they receive payment details directly; we do not store credit card numbers)
- Analytics: Privacy-respecting analytics tools for usage insights
- Waitlist management: Formspree (for processing waitlist form submissions)
Service Providers are contractually bound to use your data only as instructed and for the purposes specified. They are required to maintain appropriate security measures.
Authentication providers
When you sign in with Google or LinkedIn, these providers receive and share data during the OAuth flow according to their own terms. We receive only the profile information you authorize.
Legal and safety
We may disclose your information if we believe in good faith that disclosure is necessary to:
- Comply with applicable law, regulation, legal process, or enforceable governmental request
- Enforce our Terms & Conditions, including investigation of potential violations
- Detect, prevent, or address fraud, security, or technical issues
- Protect against harm to the rights, property, or safety of Hadithi, our users, or the public
Business transfers
In the event of a merger, acquisition, reorganization, bankruptcy, or sale of all or a portion of our assets, your information may be transferred as part of that transaction. We will provide notice before your personal information is transferred and becomes subject to a different privacy policy.
With your consent
We may share your information with third parties when you have given us explicit consent to do so.
5. Data Retention
We retain your data only for as long as necessary to fulfill the purposes for which it was collected:
| Data type | Retention period |

| Server logs (IP addresses) | 90 days |
| Payment records | As required by applicable tax and financial regulations (typically 7 years) |
| Support communications | 2 years after resolution, or as required by law |
We may retain anonymized or aggregated data that cannot be used to identify you for longer periods for analytical purposes.
When retention is required by law (such as tax records or legal disputes), we will retain only the minimum necessary data for the legally required period.
6. Data Security
We implement reasonable and appropriate technical and organizational measures to protect your personal data against unauthorized access, alteration, disclosure, or destruction. These measures include:
Technical measures
- Encryption in transit: All data transmitted between your browser and our servers is encrypted using TLS (Transport Layer Security).
- Encryption at rest: Sensitive fields (such as OAuth tokens and refresh tokens) are encrypted at the application level using Active Record encryption.
- Access controls: Database access is restricted to authorized services and personnel. Administrative access requires multi-factor authentication.
- Secure authentication: Passwords are hashed using industry-standard algorithms. OAuth tokens are encrypted and never exposed in logs or responses.
- Input validation: All user inputs are validated and sanitized to prevent injection attacks and other vulnerabilities.
Organizational measures
- Access to personal data is limited to personnel who need it to perform their duties.
- We conduct regular security reviews of our codebase and infrastructure.
- Service Providers are required to maintain appropriate security standards.
No method of electronic transmission or storage is 100% secure. While we strive to protect your data using commercially reasonable means, we cannot guarantee absolute security. If you become aware of a security vulnerability or breach, please report it to security@hadithi.org.
7. Data Breach Notification
In the event of a data breach that is likely to result in a risk to your rights and freedoms, we will:
- Notify affected users without undue delay, and within 72 hours of becoming aware of the breach where required by applicable law (such as the GDPR)
- Notify the relevant supervisory authority where required by law
- Provide details about the nature of the breach, the data involved, the likely consequences, and the measures taken to address it
- Take immediate steps to contain, investigate, and remediate the breach

Most browsers allow you to control cookies through settings. Disabling essential cookies may prevent you from using the Service.
10. Children's Privacy
Hadithi is not intended for users under 18 years of age. We do not knowingly collect personal information from children under 18. If you are a parent or guardian and believe that your child has provided us with personal information, please contact us at privacy@hadithi.org. If we become aware that we have collected personal information from a child under 18 without parental consent, we will take steps to delete that information promptly.
11. International Data Transfers
Your data may be transferred to, stored in, and processed in countries other than the one in which you reside. These countries may have data protection laws that differ from those in your jurisdiction.
Where we transfer personal data from the European Economic Area (EEA), United Kingdom (UK), or Switzerland to countries that have not been deemed to provide an adequate level of protection, we ensure appropriate safeguards are in place, such as:
- Standard Contractual Clauses (SCCs) approved by the European Commission
- Data processing agreements with appropriate security and confidentiality obligations
- Transfers to countries recognized as providing adequate protection
You can request information about the safeguards in place for international transfers by contacting us.
12. Do Not Track Signals
Some browsers transmit "Do Not Track" (DNT) signals. Since there is no industry consensus on how to respond to DNT signals, we do not currently respond to them. However, as described in Section 9, we do not use third-party tracking cookies or cross-site tracking technologies.
13. Third-Party Links
The Service may contain links to third-party websites or services that are not operated by us. We have no control over and assume no responsibility for the content, privacy policies, or practices of any third-party websites or services. We encourage you to review the privacy policy of every site you visit.
