Privacy Policy for Doctor Iota Applications
Effective date: 2025-08-12
This Privacy Policy explains what information Doctor Iota’s applications (“our apps”, “our services”, “we”, “us”) process when you use them, why we process it, and the choices you have. We design for privacy and collect only what is necessary to provide the experience described in each app’s documentation.
If you have questions or requests, contact: dr2iota@gmail.com.
What our applications do
We create applications focused on mathematical art, education, and recreation. Our apps are designed to be interactive and educational. Examples include:
- Fantastic Fractals: An interactive fractal explorer (e.g., Mandelbrot, Julia, Newton) with real‑time pan/zoom, color palettes, and share‑by‑link.
- Triangular Geometry: An interactive geometry playground for exploring triangles, their properties, and animated proofs.
In the future, we may add optional user accounts and multi‑user experiences (e.g., shared sessions or games) to our apps. We will continue to follow a strict data‑minimization approach across all our services.
Summary
- We do not sell your data, serve targeted ads, or share personal information with third parties for their own marketing.
- Our apps are fully functional without an account and currently operate entirely on your device without connecting to any server.
- We store settings locally on your device (e.g., theme setting and user-customized color schemes). In the future, we may also save language and speaker settings. Share links encode view parameters in the URL.
- As our apps run locally, we do not have server logs and are unable to collect any user information. In the future, if we introduce server-side features, this will change and we will update this policy.
- We do not use cookies.
Currently, our applications run entirely locally on your device. They do not connect to any server, and therefore we do not process or collect any personal information.
- App preferences and parameters: When you adjust controls (e.g., theme, color schemes), that information is stored locally in the app or in your browser for the web version. This information is not transmitted to us. URLs you choose to share in the web version may contain parameters that describe the view.
- Optional feedback or support messages: If you contact us via email, we will receive the information you include in your message.
- Our apps do not connect to any server, so no information is processed automatically by us. We do not use cookies. We use the app’s local storage or your browser’s local storage (for the web version) to save your settings.
- Device/runtime capabilities: Our apps may read capabilities (e.g., WebGL features) locally to adapt rendering. This information stays on-device and is not sent to us.
Future features (accounts and multiplayer)
If we introduce accounts or multi‑user experiences in any of our apps, we will process only the minimum data required. These features would require a server connection.
- Account identifiers: For example, an email address or an OAuth provider identifier, plus authentication tokens. We will not request profile details beyond what is necessary to authenticate and provide the service.
- Display name (optional): If shown to other users in multiplayer contexts.
- Session and game/fractal state: Parameters needed to synchronize a shared session (e.g., current view, room/session IDs). This may be visible to other participants you explicitly join.
- Moderation/anti‑abuse signals: Minimal metadata strictly needed to keep the service safe (e.g., rate limiting data, rule violations where applicable).
- Basic service logs: Our hosting and security systems may log standard metadata such as IP address, request headers, timestamps, error details, and basic performance metrics. This is used for operations (e.g., troubleshooting, abuse prevention) and kept for a limited retention period.
We will update this policy and, where required, request consent before launching such features.
- Provide and improve our apps, including rendering, performance, and reliability.
- Offer requested features such as share‑by‑link; links may contain parameters that reveal your current view/choices to anyone with the link.
- Communicate with you about our apps if you reach out to us.
Legal bases (EEA/UK users)
Where applicable, we rely on the following legal bases:
- Performance of a contract: To provide our apps and requested features.
- Legitimate interests: For security, fraud prevention, service quality, and basic analytics aligned with user expectations (applicable if we introduce server-side features).
- Consent: Where required (e.g., optional analytics or new features). You can withdraw consent at any time.
Analytics
Currently, we do not run any analytics. If we add privacy‑preserving analytics in the future, it will be limited to aggregate, non‑identifying metrics and/or self‑hosted solutions. Where required, we will request consent and provide opt‑out controls.
Data sharing
We do not sell personal data. As our apps do not have a server component, we do not share data with any third parties.
In the future, if server-side features are added, we may share information with:
- Service providers (e.g., hosting, error logging) under agreements that restrict their use of data to our instructions.
- Legal and safety: If required by law or to protect the rights, property, or safety of users or the public.
Data retention
- Local preferences: Stored on your device until you clear them.
- Server logs/diagnostics (future): If we introduce server features, logs will be retained only as long as necessary for operations and security, then deleted or anonymized.
- Account and multiplayer data (future): Retained for as long as your account or session is active and for a reasonable period thereafter for backup, security, or legal compliance.
International transfers
Our apps currently run locally on your device. If we introduce server-based features in the future that involve transferring data across borders, we will use appropriate safeguards (e.g., Standard Contractual Clauses) where required by law.
Your rights
Depending on your location, you may have rights to access, correct, delete, or export your information, and to object to or restrict certain processing. As we do not currently hold any of your personal information, these rights are not applicable at this time. To exercise these rights in relation to future services or for any privacy-related questions, contact us using the details above. We will honor these requests as required by applicable law.
Children’s privacy
Our applications are not directed to children under 13 (or the age required by your jurisdiction). We do not knowingly collect personal data from children. If you believe a child has provided personal data, please contact us to remove it.
Security
We use reasonable administrative, technical, and organizational measures to protect information. Our apps are designed to be secure by default, with minimal privileges. They do not require internet access to function. Any external links are opened in your device’s default browser, not within the application itself. No system is 100% secure; we encourage you to use current software and secure your devices.
Changes to this policy
We may update this policy to reflect changes in our apps or law. We will post the updated version here and revise the effective date. Material changes will be highlighted within the relevant app(s) where appropriate.
