Terms of Service

1. Acceptance

By using Thremark, you agree to these terms. If you do not agree, please do not use the app.

2. The service

Thremark is an AI chat assistant that remembers facts you share (“Marks”). The app provides AI-powered conversations using third-party providers (OpenAI, Google Gemini), including reasoning models, web search via Tavily, real-time Voice AI conversations via Google Gemini Live and OpenAI Realtime, voice input via speech-to-text, and AI-generated files. AI responses are generated content and may contain errors. Do not rely on them for medical, legal, or financial advice.

3. Subscriptions

• Pro ($29.99/mo) — unlimited messages, unlimited Voice AI, thinking 30/day + deep reasoning 10/day, unlimited marks & files, unlimited search.
• Payment will be charged to your Apple ID account at confirmation of purchase. Subscriptions automatically renew unless canceled at least 24 hours before the end of the current period. Your account will be charged for renewal within 24 hours prior to the end of the current period at the same price.
• You can manage and cancel subscriptions in iOS Settings > Apple ID > Subscriptions, or from within the app via Settings > Manage Subscription.
• Any unused portion of a free trial period (if offered) will be forfeited when the user purchases a subscription.

Subscriptions are governed by Apple's Standard End User License Agreement (EULA).

4. Acceptable use

You agree not to use Thremark to:

• Generate illegal, harmful, or abusive content
• Attempt to bypass safety filters or rate limits
• Reverse-engineer the app or its communication with servers
• Use the service for automated scraping or data harvesting

5. Your data

You own your marks and chat history. Thremark stores data on your device and optionally in your iCloud account. See our Privacy Policy for details.

6. Account deletion

When you delete your account, all data stored on your device and in iCloud is permanently removed. Server-side data (marks, files, usage metadata) is automatically purged within 30 days of account deletion or can be deleted immediately by contacting us.

7. Limitation of liability

Thremark is provided “as is” without warranties of any kind. We are not liable for data loss, AI inaccuracies, service interruptions, or any indirect damages arising from use of the app.

8. Voice AI & voice input

Thremark offers real-time Voice AI conversations where audio is streamed to Google Gemini Live API or OpenAI Realtime API for processing. During a voice session, your AI can automatically extract and save facts (marks) and create files, just like in text chat. Audio is not stored after the session ends.

Voice input (push-to-talk) uses speech-to-text transcription via our proxy server. Audio is not stored after transcription. The resulting text is treated as a regular chat message.

9. Files

Thremark may create files from long AI responses or on your request. Files are stored on your device and optionally synced via iCloud. You can view, rename, share, and delete files at any time.

10. GitHub Sync

If you connect GitHub Sync (Plus/Pro), Thremark creates a private repository in your GitHub account and pushes your marks and files as markdown. Your GitHub OAuth token is stored encrypted on our server. You can disconnect at any time from Settings, which revokes access and deletes the stored token.

11. Intellectual property

You retain ownership of any content you create using Thremark, including marks, files, and chat messages. AI-generated responses are provided for your personal use. The Thremark name, logo, and interface design are the property of Thremark.

12. Termination

We may suspend or terminate access if these terms are violated. You can stop using Thremark at any time and delete all data from Settings.

13. Governing law

These terms are governed by and construed in accordance with applicable law. Any disputes will be resolved through good-faith negotiation before pursuing formal proceedings.

14. Changes

We may update these terms as features ship. Continued use after changes constitutes acceptance.
