Privacy Policy

Last updated: February 24, 2026

1. Introduction

paceai ("Pace," "we," "us," or "our") is committed to protecting your privacy. This Privacy Policy explains how we collect, use, disclose, and safeguard your information when you use our smart glasses, companion mobile application, website (paceai.dev), and related services (collectively, the "Services").

2. Information We Collect

2.1 Information You Provide

Account information: name, email address, and password when you create an account
Profile preferences: reading speed targets, highlight colors, accessibility mode selections
Waitlist information: email address submitted through our website
Support requests: communications you send to us

2.2 Information Collected Automatically

Reading session data: words per minute (WPM), session duration, pages read, reading frequency, and comprehension quiz scores
Eye-tracking metrics: fixation duration, saccade patterns, regression frequency, and blink rate — processed entirely on-device and never transmitted in raw form
Device data: glasses firmware version, mobile app version, device model, operating system
Usage analytics: feature usage patterns, session timestamps, and performance metrics

2.3 Information We Do NOT Collect

We do not store the text content of books, documents, or any material you read
We do not transmit raw camera images from the glasses to our servers
We do not record or store raw eye-tracking video data
OCR text processing happens entirely on-device; only anonymized metadata (word count, difficulty score) is synced

3. How We Use Your Information

To provide, maintain, and improve the Services
To personalize your reading experience through our adaptive AI models
To generate reading analytics, summaries, and progress reports
To communicate with you about updates, features, and support
To conduct research and development to improve our AI models (using anonymized, aggregated data only)
To comply with legal obligations

4. AI Model Training

Our adaptive speed engine and comprehension models improve over time using anonymized reading behavior data. Specifically:

On-device models use federated learning — your model improves locally, and only gradient updates (not your data) are sent to our servers
Aggregated, de-identified reading patterns may be used to improve our global AI models
You can opt out of contributing to global model improvement in your account settings
Individual reading content is never used for model training

5. Data Storage and Security

All data is encrypted at rest (AES-256) and in transit (TLS 1.3)
Reading session data is stored locally on your device first (SQLite) and synced to our cloud servers (AWS, US region) only with your permission
Eye-tracking data is processed on-device and never leaves the glasses in raw form
We maintain SOC 2 Type II compliance standards
Access to personal data is restricted to authorized personnel on a need-to-know basis

6. Data Sharing

We do not sell your personal information. We may share data only in these circumstances:

Service providers: cloud hosting (AWS), analytics (Plausible), and email services that process data on our behalf under strict data processing agreements
Education partners: if you use Pace through a school program, aggregated (not individual) reading progress may be shared with your institution, with your consent
Legal requirements: when required by law, regulation, or legal process
Business transfers: in connection with a merger, acquisition, or sale of assets, with prior notice to you

7. Children's Privacy (COPPA)

Pace is not directed to children under 13. If Pace is used in a school setting with children under 13, we require verifiable parental consent and comply with the Children's Online Privacy Protection Act (COPPA). Schools acting as agents of parents may provide consent on their behalf in accordance with COPPA and FERPA.

8. Student Data (FERPA)

When Pace is used in educational settings, we comply with the Family Educational Rights and Privacy Act (FERPA). Student reading data is treated as an education record. We act as a "school official" with a "legitimate educational interest" and do not use student data for advertising or non-educational purposes.

9. Your Rights

Depending on your jurisdiction, you may have the right to:

Access the personal data we hold about you
Correct inaccurate data
Delete your data ("right to be forgotten")
Export your data in a portable format (CSV, JSON)
Opt out of AI model training contributions
Withdraw consent for data processing

To exercise these rights, contact us at privacy@paceai.dev. We respond to all requests within 30 days.

10. Data Retention

We retain your data for as long as your account is active. If you delete your account, we delete all personal data within 30 days, except where retention is required by law. Anonymized, aggregated data that cannot be linked back to you may be retained indefinitely for research purposes.

11. International Data Transfers

Your data may be processed in the United States. If you are located outside the US, your information is transferred subject to appropriate safeguards, including Standard Contractual Clauses where required by GDPR.

12. Changes to This Policy

We may update this Privacy Policy from time to time. We will notify you of material changes by email or through the app. Continued use of the Services after changes constitutes acceptance of the updated policy.
