Privacy Policy
Effective date: February 23, 2026 · Last updated: February 23, 2026
1. Introduction
Special Glasses LLC ("Special Glasses," "we," "us," or "our") builds apps that help people see the world differently. This Privacy Policy explains what information we collect, how we use it, who we share it with, and the rights you have over your data.
This policy covers all products and services operated by Special Glasses, including:
- What They See — an iOS app that simulates vision conditions through real-time camera filters
- specialglasses.net — our website
We may introduce additional products in the future, each of which will have its own detailed privacy disclosures before launch.
By using our products, you agree to the practices described in this policy. If you do not agree, please do not use our products or services.
2. What They See — Data Practices
What They See is designed with privacy at its core. The app simulates vision conditions (such as color blindness, low vision, and dyslexia) using real-time camera filters. Here is exactly what happens with your data:
2.1 Camera and On-Device Processing
- All camera processing happens entirely on your device using Apple's Metal shaders, Core Image, and LiDAR hardware. No camera data is ever transmitted to our servers or any third party.
- We do not collect, store, or have access to any images, video, or camera data.
- Photos and videos you choose to capture are saved only to your device's Photos library. We never access, upload, or process these files.
- Dyslexia simulation uses Apple's on-device Foundation Models, which run entirely on your device without any cloud processing.
2.2 Purchase Information
What They See offers one-time in-app purchases processed by Apple through the App Store. We do not have access to your payment information (credit card number, billing address, etc.). We use RevenueCat, a third-party service, to manage purchase status. RevenueCat receives:
- An anonymous app user ID
- Purchase and transaction history from Apple
- Device type and OS version
RevenueCat stores this data on Amazon Web Services (AWS) in the United States. For details, see RevenueCat's Privacy Policy.
2.3 Analytics and Crash Reporting
We use Google Firebase to understand how the app is used and to fix bugs:
- Firebase Analytics collects anonymous usage data such as screen views, app events, device type, OS version, country, and language. This data is not linked to your identity.
- Firebase Crashlytics collects crash reports including stack traces, device state, and an installation UUID to help us diagnose and fix issues. Crashlytics also collects your IP address, which is used only for crash grouping and is not stored long-term.
You can opt out of analytics data collection by disabling analytics in your device settings. Crashlytics data collection is essential for app stability and cannot be individually disabled, but it does not collect personal content or identify you by name or email.
2.4 Data We Do Not Collect
What They See does not collect:
- Your name, email address, or contact information
- Location data (GPS, Wi-Fi, or Bluetooth-based)
- Health or medical data
- Browsing history or search history
- Contacts, messages, or call logs
- Biometric data (facial recognition, fingerprints)
- Any user-generated content
3. Website — specialglasses.net
- No cookies. Our website does not use cookies or client-side tracking scripts.
- Server-side analytics. Our website is hosted on Cloudflare Pages. Cloudflare may collect basic server-side analytics (page views, country-level geolocation, browser type) for security and performance purposes. This data is aggregated and does not identify individual visitors. See Cloudflare's Privacy Policy.
- Contact form. Our contact page uses Google Forms. If you submit a contact form, your response is stored in Google's systems and is accessible to us. See Google's Privacy Policy.
4. Legal Bases for Processing
For users in the European Economic Area (EEA), United Kingdom, and other jurisdictions that require a legal basis for processing personal data, we rely on the following:
- Contractual necessity. Processing purchase data through RevenueCat is necessary to deliver the products you bought.
- Legitimate interests. We use Firebase Analytics and Crashlytics to improve app quality, fix bugs, and understand usage patterns. We balance these interests against your privacy by collecting only anonymous or pseudonymous data.
- Consent. Where required by law, we obtain your consent before collecting data (for example, through App Tracking Transparency prompts on iOS).
- Legal obligation. We may process data to comply with applicable laws or respond to lawful government requests.
5. Third-Party Services
We use the following third-party services. Each is bound by their own privacy policies and data processing agreements:
- Apple (App Store) — processes in-app purchases and provides app distribution. Apple Privacy Policy
- RevenueCat — manages purchase status and entitlements. RevenueCat Privacy Policy
- Google Firebase (Analytics & Crashlytics) — provides anonymous usage analytics and crash reporting. Firebase Privacy & Security
- Cloudflare — hosts our website and provides security and performance services. Cloudflare Privacy Policy
- Google Forms — powers our contact form. Google Privacy Policy
We require that all third-party service providers handle your data with the same or greater level of protection described in this policy.
6. Data Retention
- Camera data: Not retained. Never leaves your device.
- Purchase data (RevenueCat): Retained for as long as necessary to manage your purchases and provide customer support. You can request deletion by contacting us.
- Analytics data (Firebase): Retained for up to 14 months by Google, then automatically deleted.
- Crash data (Crashlytics): Retained for 90 days by Google.
- Contact form submissions: Retained until we resolve your inquiry, then deleted within 12 months unless we need to keep it for legal reasons.
7. International Data Transfers
Some of our third-party service providers (RevenueCat, Google Firebase) process data in the United States. If you are located outside the United States, your data may be transferred to and processed in the United States, where data protection laws may differ from those in your country.
For transfers from the EEA, UK, or Switzerland, we rely on:
- Standard Contractual Clauses (SCCs) approved by the European Commission
- Data Processing Agreements (DPAs) with our service providers
- Where applicable, adequacy decisions by relevant authorities
For transfers from Brazil, we comply with LGPD requirements for international data transfers, including the use of standard contractual clauses approved by the Brazilian Data Protection Authority (ANPD).
8. Data Security
We take reasonable technical and organizational measures to protect the data processed through our services. Our primary security measure is minimizing data collection in the first place: What They See processes all sensitive data (camera, photos, video) entirely on your device.
For data handled by our third-party providers, we rely on their security practices, which include encryption in transit and at rest, access controls, and regular security audits. No method of electronic storage or transmission is 100% secure, so we cannot guarantee absolute security.
9. Children's Privacy
What They See may be used by or on behalf of children to demonstrate vision conditions. We take children's privacy seriously.
- No personal data from children. What They See does not collect personal information from any user, including children under 13 (or under 16 in the EEA). Camera data is processed entirely on-device and never transmitted.
- Analytics data is anonymous. Firebase Analytics and Crashlytics collect only anonymous technical data (device type, crash logs). This data cannot be used to identify a child.
- No accounts required. What They See does not require account creation, so no names, email addresses, or other identifiers are collected from children.
- COPPA compliance. Because we do not knowingly collect personal information from children under 13, we believe our practices comply with the Children's Online Privacy Protection Act (COPPA) and its 2025 amendments. If we learn that we have inadvertently collected personal information from a child under 13, we will delete it promptly.
If you are a parent or guardian and believe your child has provided personal information to us, please contact us at spatial@specialglasses.net so we can take appropriate action.
10. Your Rights Under GDPR (EEA & UK)
If you are located in the European Economic Area or the United Kingdom, you have the following rights under the General Data Protection Regulation (GDPR) and UK GDPR:
- Right of access. You can request a copy of any personal data we hold about you.
- Right to rectification. You can ask us to correct inaccurate data.
- Right to erasure ("right to be forgotten"). You can ask us to delete your personal data.
- Right to restrict processing. You can ask us to limit how we use your data.
- Right to data portability. You can request your data in a structured, machine-readable format.
- Right to object. You can object to our processing of your data based on legitimate interests.
- Right to withdraw consent. Where processing is based on consent, you can withdraw that consent at any time.
- Right to lodge a complaint. You have the right to file a complaint with your local data protection supervisory authority.
To exercise any of these rights, contact us at spatial@specialglasses.net. We will respond within 30 days.
Because What They See collects very limited data and does not require accounts, in most cases there is no personal data for us to provide, correct, or delete. If you have made a purchase, we can request deletion of your RevenueCat data on your behalf.
11. Your Rights Under CCPA/CPRA (California)
If you are a California resident, the California Consumer Privacy Act (CCPA), as amended by the California Privacy Rights Act (CPRA), provides you with specific rights regarding your personal information:
- Right to know. You can request that we disclose what personal information we have collected, used, disclosed, or sold about you in the preceding 12 months.
- Right to delete. You can request deletion of your personal information.
- Right to correct. You can request correction of inaccurate personal information.
- Right to opt out of sale or sharing. You can opt out of the sale or sharing of your personal information. We do not sell your personal information and do not share it for cross-context behavioral advertising.
- Right to limit use of sensitive personal information. You can limit the use and disclosure of sensitive personal information. We do not collect sensitive personal information as defined by the CCPA.
- Right to non-discrimination. We will not discriminate against you for exercising any of your privacy rights.
Categories of personal information collected in the past 12 months:
- Identifiers: Anonymous installation UUIDs (via Firebase Crashlytics). We do not collect names, email addresses, or account names through the app.

12. Your Rights Under LGPD (Brazil)
If you are located in Brazil, the Lei Geral de Proteção de Dados (LGPD) grants you the following rights:
- Confirmation of whether your data is being processed
- Access to your personal data
- Correction of incomplete, inaccurate, or outdated data

13. Other Jurisdictions
We respect privacy rights globally. If you are located in a jurisdiction with privacy laws not specifically addressed above (including but not limited to Canada's PIPEDA, Australia's Privacy Act, Japan's APPI, South Korea's PIPA, or US state privacy laws in Virginia, Colorado, Connecticut, Utah, Texas, Oregon, Montana, and others), you may have similar rights to access, correct, and delete your personal data.
Regardless of where you are located, you can contact us at spatial@specialglasses.net to exercise your privacy rights, and we will respond in accordance with applicable law.
14. Do Not Track & Opt-Out Preference Signals
Our website does not use cookies or client-side tracking, so there is no tracking behavior to modify in response to Do Not Track (DNT) or Global Privacy Control (GPC) signals. We honor opt-out preference signals where required by law.
In the What They See app, you can limit analytics data collection through your iOS device settings (Settings > Privacy & Security > Analytics & Improvements).
15. Automated Decision-Making
We do not use automated decision-making or profiling that produces legal effects or similarly significant effects on you. The on-device AI processing in What They See (dyslexia simulation via Apple Foundation Models) runs entirely on your device, is not used for decision-making about you, and produces no data that is transmitted to us.
16. Changes to This Policy
We may update this privacy policy from time to time, particularly as we launch new products. When we make changes, we will:
- Update the "Last updated" date at the top of this page
- Post the revised policy on this page
- For material changes, provide notice through the app or by other appropriate means
We encourage you to review this policy periodically. Your continued use of our products after changes are posted constitutes acceptance of the updated policy.
