Terms of Use
Effective date: February 23, 2026 · Last updated: February 23, 2026
1. Agreement
By downloading, installing, or using ContextorAI ("the App" or "Service"), you agree to these Terms of Use ("Terms"). If you do not agree, do not use the App.
ContextorAI is operated by ContextorAI, a Delaware corporation ("we", "us", "our").
2. The Service
ContextorAI is a personal AI knowledge base that allows you to capture, store, search, and interact with your notes, files, and other content using artificial intelligence.
The Service includes mobile and desktop applications (iOS, macOS, Android, Windows), cloud sync and storage, AI processing (auto-tags, summaries, semantic search, AI chat), a Telegram bot, and APIs.
3. Accounts
You must create an account to use the Service. You are responsible for providing accurate account information, keeping your credentials secure, and all activity that occurs under your account.
We support sign-in via Apple and Google. We do not store your password — authentication is delegated to Apple or Google.
You must be at least 13 years old to use the Service, or the minimum age required by applicable law in your jurisdiction. If you are under 18, you must have parental consent.
4. Subscriptions and Billing
4.1 Plans
| Plan | Price | Storage | Cloud AI |
|---|---|---|---|
| Free | $0 | 1 GB | 10 requests/day |
| Premium | $9.99/mo or $79.99/yr | 5 GB | Unlimited |
| Pro | $19.99/mo or $149.99/yr | 50 GB | Unlimited |
4.2 Billing
Subscriptions are billed in advance on a monthly or annual basis. Payments are processed through the Apple App Store, Google Play, or Stripe depending on your platform. Applicable taxes may be added.
4.3 Cancellation
You may cancel at any time through your account settings or the platform through which you subscribed. Cancellation takes effect at the end of the current billing period — you retain access until that date.
4.4 Refunds
We do not offer refunds for partial billing periods, except where required by applicable law. For purchases made through the App Store or Google Play, refund requests are subject to Apple's or Google's refund policies. EU and UK consumers have statutory cancellation rights — see Section 18.
4.5 Downgrades
If you downgrade to a lower tier and your data exceeds the new storage limit, existing data remains accessible and is not deleted immediately. New uploads will be blocked until you reduce usage below the new limit. You have 30 days to do so before we begin declining new uploads.
4.6 Price changes
We will give you at least 30 days notice before increasing subscription prices. You may cancel before the new price takes effect without penalty.
5. Your Content
5.1 Ownership
You own all content you create or upload to the App ("Your Content"). We claim no ownership over Your Content.
5.2 License to us
By using the Service, you grant us a limited, non-exclusive, royalty-free license to store, process, and transmit Your Content solely to provide the Service to you. This license ends when you permanently delete Your Content or close your account.
5.3 Cloud notes and AI processing
Cloud notes are encrypted on our servers with a key we control. This allows us to run AI processing (auto-tags, summaries, embeddings, semantic search), power Cloud AI chat over your notes, and sync your notes across devices.
We do not sell Your Content to third parties. We do not use Your Content to train AI models without your explicit consent.
When you use Cloud AI chat, your query and relevant note excerpts are sent to our AI providers (currently Google and OpenAI) to generate a response. Our AI providers are bound by data processing agreements and contractually prohibited from using your data to train their models.
5.4 Locked notes (end-to-end encrypted)
Locked notes are encrypted end-to-end using a key only you control (your Master Key). We have no ability to read the content of Locked notes. All AI processing for Locked notes occurs exclusively on your device using the local AI model. No Locked note content is ever transmitted to our servers in readable form.
You are solely responsible for maintaining access to your Master Key and Recovery Key. If you lose access to all your devices and your Recovery Key, Locked note content cannot be recovered by you or by us. Back up your Recovery Key in a secure location.
5.5 Responsibility for content
You are responsible for Your Content. You agree not to upload or transmit content that violates any applicable law, infringes third-party intellectual property rights, contains malware or malicious code, constitutes harassment or hate speech, or otherwise violates these Terms.
6. AI Features
6.1 AI output accuracy
AI-generated content (auto-tags, summaries, chat answers, context notes) is provided as-is and may contain errors or inaccuracies. Do not rely on AI output for medical, legal, financial, or other professional decisions without independent verification.
6.2 Local AI
The local AI model runs entirely on your device. No data is sent to our servers or any third party when using local AI.
6.3 Cloud AI
Cloud AI sends your query and relevant excerpts from your Cloud notes to our AI providers to generate a response. Locked note content is never included in Cloud AI requests.
6.4 AI usage limits
The Free tier is limited to 10 Cloud AI chat requests per day, resetting at midnight UTC. Automatic background processing (auto-tags, summaries, embeddings) does not count toward this limit.
7. Storage
7.1 Storage quota
Your storage quota is shared across Cloud notes, Locked notes, and all attachments. Items in Trash count toward your quota until permanently deleted.
| Plan | Included | Additional |
|---|---|---|
| Free | 1 GB | Not available |
| Premium | 5 GB | $0.99 per 10 GB |
| Pro | 50 GB | $0.99 per 10 GB |
7.2 Trash retention
Deleted items are moved to Trash and permanently deleted after:
- Free: 7 days
- Premium: 30 days
- Pro: 90 days
After permanent deletion, content cannot be recovered.
7.3 File size
There is no per-file size limit. The technical ceiling is 2 GB per file. Your storage quota is the effective limit.
8. Acceptable Use
You agree not to:
- Reverse engineer, decompile, or disassemble the App or its AI models
- Use the App to store, transmit, or process illegal content

THE SERVICE IS PROVIDED "AS IS" AND "AS AVAILABLE" WITHOUT WARRANTIES OF ANY KIND, EXPRESS OR IMPLIED. TO THE MAXIMUM EXTENT PERMITTED BY APPLICABLE LAW, WE DISCLAIM ALL WARRANTIES INCLUDING WARRANTIES OF MERCHANTABILITY, FITNESS FOR A PARTICULAR PURPOSE, NON-INFRINGEMENT, AND UNINTERRUPTED OR ERROR-FREE OPERATION.

CRITICAL: IF YOU LOSE YOUR MASTER KEY AND RECOVERY KEY FOR LOCKED NOTES, WE CANNOT RECOVER YOUR CONTENT. THIS IS INHERENT TO END-TO-END ENCRYPTION AND IS NOT A SERVICE FAILURE.
Nothing in these Terms limits our liability for death or personal injury caused by our negligence, fraud, or any other liability that cannot be excluded by law.
17. Dispute Resolution and Arbitration
17.1 Informal resolution
Before initiating any formal dispute, you agree to contact us at legal@contextorai.com and give us 30 days to resolve the issue informally.
17.2 Binding arbitration
If informal resolution fails, any dispute arising from these Terms or the Service shall be resolved by binding individual arbitration administered by the American Arbitration Association (AAA) under its Consumer Arbitration Rules, except as set out in Section 17.4.
Arbitration will take place in San Francisco, California, or via video conference. The arbitrator's decision is final and may be entered as a judgment in any court of competent jurisdiction.

EU and UK users: mandatory consumer protection laws of your country of residence apply in addition to these Terms and cannot be waived by this governing law clause.
19. General
Entire agreement. These Terms, together with our Privacy Policy, constitute the entire agreement between you and us regarding the Service.
Severability. If any provision of these Terms is found unenforceable, it will be modified to the minimum extent necessary to make it enforceable, and the remaining provisions will continue in full force.
No waiver. Our failure to enforce any right or provision of these Terms does not constitute a waiver of that right or provision.
Assignment. You may not assign your rights under these Terms without our prior written consent. We may assign our rights in connection with a merger, acquisition, or sale of assets.
20. Changes to Terms
We may update these Terms from time to time. For material changes, we will notify you by email or in-app notification at least 14 days before the new Terms take effect.
