Overview
Skeletal Formula ("the App") is a Canva app developed by Naveen Bhavnani that allows users to search molecules and insert publication-quality skeletal structure diagrams into their Canva designs.
Information We Collect
We do NOT collect any personal information or transmit user data to our own servers.
The App operates entirely within the Canva platform and:
- Does not require user login or authentication
- Does not collect names, email addresses, or contact information
- Does not track user behavior or analytics
- Does not use cookies or tracking technologies
- Does not transmit any personal data to external servers
How the App Works
The App works in two stages:
- Molecule Search: When you search by name, molecular formula, or CAS number, the App sends your search query directly from your browser to the PubChem public API (operated by the National Institutes of Health) to retrieve molecule data. No personal information is included in these requests.
- Diagram Rendering: The skeletal structure diagram is generated entirely in your browser using the SmilesDrawer library. No data is sent externally for rendering.
When you enter a SMILES string directly, no external API call is made at all — the diagram is rendered entirely locally.
Data Processing
The molecule search queries and SMILES strings you enter into the App are:
- Used only to search for molecules and generate skeletal diagrams
- Not stored by our App after you close it
- Not associated with any personal information
Third-Party Libraries
The App uses the following open-source library for molecular structure rendering:
- SmilesDrawer - An open-source JavaScript library for rendering SMILES notation to SVG. Licensed under the MIT License. Source: github.com/reymond-group/smilesDrawer
This library runs entirely in your browser and does not transmit any data externally.
Third-Party Services
The App connects to the following third-party service:
- PubChem PUG REST API - A free, public API operated by the National Center for Biotechnology Information (NCBI), part of the U.S. National Institutes of Health (NIH). The App sends molecule search queries (names, formulas, CAS numbers) to this API to retrieve SMILES strings and molecule metadata. PubChem's privacy policy is available at NLM Web Policies.
The App does not integrate with any analytics platforms or advertising networks.
Generated Diagrams
When you create skeletal structure diagrams:
- The diagram is rendered locally in your browser
- No record of your diagrams is kept by the App
- The generated images are uploaded to Canva for use in your design
- We have no way to retrieve or see diagrams you have created
Canva Platform
This App runs within the Canva platform. Your use of Canva is governed by:
Canva may collect data about your use of their platform according to their own privacy policy. This App does not have access to or control over Canva's data collection practices.
Children's Privacy
The App does not knowingly collect information from children under 13 years of age. The App is designed for chemistry educators, students, and content creators of all ages, but does not collect any personal data.
Data Security
Since we do not collect or transmit any user data to our own servers, there is no user data at risk from our side. All communication with PubChem uses HTTPS encryption.
Your Rights
Since we do not collect personal data on our servers, there is no data to access, modify, or delete from our end. You have complete control over:
- The molecule searches you perform
- Any skeletal diagrams you generate
Changes to This Privacy Policy
We may update this Privacy Policy from time to time. Any changes will be posted on this page with an updated "Last Updated" date. We encourage you to review this Privacy Policy periodically.
International Users
The App is available globally through the Canva platform. Since we do not collect any data on our own servers, there are no cross-border data transfer concerns from our side. Note that molecule search queries are sent to PubChem servers located in the United States.
