Privacy Policy
Last updated: 2026-04-25
1. Who We Are
IOLDx Clinical is operated by PrecisionIOL (precisioniol.com). We provide a browser-based IOL power calculation tool for cataract surgeons. Contact: support@precisioniol.com
2. What Data We Collect
Biometry data: All biometry values (axial length, keratometry, etc.) are entered locally and processed entirely within your browser. No patient biometry data is transmitted to our servers.
Scan images (optional): If you use the AI scan import feature, your biometer image is sent to Anthropic's Claude API via a secure server-side proxy for text extraction only. Images are not stored. You will be shown an explicit consent prompt before any image is transmitted. See Security page for details.
Analytics: We use Google Analytics 4 (GA4, ID: G-P292GTPPNF) to collect anonymised usage data including page views, session duration, and general geographic region. GA4 collects a browser fingerprint and IP-derived location. This data is used solely to improve the tool.
Newsletter signup (optional): If you subscribe to clinical updates, we collect your email address. This is stored securely and used only to send IOL data and feature update notifications. You can unsubscribe at any time.
Local storage: The app uses your browser's localStorage to remember preferences (e.g. disclaimer acceptance, surgeon constants). This data never leaves your device.
3. Legal Basis for Processing (GDPR)
For EU/EEA users, our legal bases are:
- Legitimate interests — analytics to improve a free clinical tool
- Consent — newsletter signup and scan image processing
You have the right to access, correct, or delete your personal data. Contact support@precisioniol.com to exercise these rights.
4. Google Analytics Opt-Out
You can decline analytics via the cookie consent banner shown on first visit, or at any time by installing the Google Analytics Opt-out Browser Add-on. Declining analytics does not affect calculator functionality.
5. HIPAA
IOLDx Clinical is designed to be HIPAA-compatible. No Protected Health Information (PHI) is transmitted to or stored on our servers. See our Security page for full technical details.
6. Data Retention
Analytics data is retained by Google for 26 months per GA4 defaults. Email addresses for newsletter subscribers are retained until you unsubscribe. No other personal data is retained.
7. Third-Party Services
- Google Analytics 4 — usage analytics (Google Privacy Policy)
- Anthropic Claude API — scan image parsing only, with explicit consent
- Amazon Web Services — hosting (no patient data stored)
8. Children
IOLDx Clinical is intended for use by licensed medical professionals. It is not directed at individuals under 18.
9. Changes to This Policy
We may update this policy. Material changes will be noted on this page with an updated date.
