By downloading, installing, or using ColloidNote ("the App"), you agree to be bound by these Terms of Use. If you do not agree to these terms, do not use the App.
ColloidNote is a handwriting note-taking app for iPad with AI-powered completions. The App converts your prompts into handwritten responses rendered in a natural handwriting style. ColloidNote is provided by Aniruddha Deshpande ("we", "us", "our").
You must sign in with your Apple ID to use the App's AI features and make purchases. You are responsible for maintaining the security of your Apple ID and for all activity that occurs under your account.
ColloidNote offers the following purchases:
All purchases are processed by Apple through the App Store. Refunds are handled exclusively by Apple in accordance with their refund policies.
Lifetime of the Product: References to "lifetime" access for ColloidNote Pro mean the lifetime of the product — that is, for as long as ColloidNote remains available and operational. This does not guarantee perpetual availability. We reserve the right to discontinue or substantially modify the App at any time, though we will make reasonable efforts to provide advance notice of any significant changes.
Note Completions are AI-generated responses to your handwritten prompts. Please be aware:
ColloidNote Pro users may provide their own API key for AI completions. If you choose to use this feature:
Your handwritten notes and documents are stored locally on your device and in your iCloud Drive. You retain full ownership of all content you create with ColloidNote.
When you request an AI completion, images of your notes are temporarily sent to our server for processing and are not stored. See our Privacy Policy for details on how we handle your data.
You agree not to:
ColloidNote, its design, code, and associated branding are the intellectual property of Aniruddha Deshpande. You are granted a limited, non-exclusive, non-transferable license to use the App for personal purposes in accordance with these terms.
The App is provided on an "AS IS" and "AS AVAILABLE" basis, without warranties of any kind, either express or implied. We do not warrant that:
To the maximum extent permitted by applicable law, we shall not be liable for any indirect, incidental, special, consequential, or punitive damages arising out of or related to your use of the App, including but not limited to loss of data, loss of profits, or damages resulting from reliance on AI-generated content.
We may suspend or terminate your access to the App's services if you violate these terms. Upon termination, your right to use the AI completion services will cease, but your locally stored notes and documents will remain on your device.
We may update these Terms of Use from time to time. We will notify you of significant changes through the App or by other reasonable means. Your continued use of the App after changes are posted constitutes your acceptance of the revised terms.
These terms shall be governed by and construed in accordance with the laws of India, without regard to conflict of law principles.
