Privacy Policy

Last updated: May 18, 2026

ChairSense ("we," "our," or "us") respects your privacy and is committed to protecting your personal data. This privacy policy explains how we collect, use, and safeguard your information when you use our service.

1. Information We Collect

We collect information that you provide directly to us and information automatically collected when you use our service.

Information you provide:

• Account information: name, email address, phone number
• Salon/business information: business name, address, services offered
• Staff information: stylist names, schedules, service assignments
• Appointment data: client names, phone numbers, appointment history, service types
• Payment information: processed through Stripe (we do not store card details)
• Communication data: SMS messages sent through our platform

Information collected automatically:

• Device information: browser type, operating system, device identifiers
• Usage data: pages visited, features used, time spent, click patterns
• Log data: IP address, access times, referring URLs
• Cookies and similar technologies: session cookies, analytics cookies

2. How We Use Your Information

We use the information we collect to:

• Provide, maintain, and improve our no-show prediction and waitlist management services
• Send appointment confirmations, reminders, and no-show notifications via SMS
• Process deposit payments and manage refunds
• Analyze appointment patterns to improve no-show prediction accuracy
• Communicate with you about your account, service updates, and support
• Detect and prevent fraud, abuse, or security issues
• Comply with legal obligations

3. Data Sharing and Disclosure

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

• Service providers: We use third-party services that process data on our behalf — including Stripe (payment processing), Twilio (SMS delivery), Logto (authentication), and our cloud hosting provider. These providers are contractually obligated to protect your data.
• Bookings platform integrations: When you connect a third-party booking system (Vagaro, Fresha, Booksy), we sync appointment data as you authorize. You control what data is shared and can disconnect at any time.
• Legal requirements: We may disclose information if required by law, subpoena, or other legal process.
• Business transfers: In connection with a merger, acquisition, or sale of assets, your data may be transferred.

4. Data Retention

We retain your account data for as long as your account is active. Appointment and prediction data is retained for the lifetime of your account to improve prediction accuracy. If you delete your account, we will delete your personal data within 30 days, except where retention is required by law.

5. Data Security

We implement industry-standard security measures to protect your data:

• All data is encrypted in transit (TLS/SSL) and at rest
• Authentication is handled via secure OAuth2 sessions
• Each salon's data is logically isolated (tenant isolation)
• Payment card data is never stored — processed entirely through Stripe's PCI-compliant systems
• Access controls limit data visibility to authorized personnel only

6. SMS Communications

When you use our SMS features, your salon's clients may receive text messages for appointment confirmations, reminders, and waitlist notifications. By using our service, you confirm that you have obtained proper consent from your clients to send them SMS communications. Clients can opt out of SMS at any time by replying STOP.

7. Your Rights

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

• Access the personal data we hold about you
• Request correction of inaccurate data
• Request deletion of your data
• Object to or restrict processing of your data
• Data portability — receive your data in a structured, machine-readable format

To exercise any of these rights, contact us at the information below.

8. Cookies

We use essential cookies to maintain your authenticated session and analytics cookies to understand how our service is used. You can manage cookie preferences through your browser settings. Disabling essential cookies may affect functionality.

9. Third-Party Links

Our service may contain links to third-party websites or integrations. We are not responsible for the privacy practices of those third parties. We encourage you to review their privacy policies.

10. Children's Privacy

Our service is not directed to individuals under the age of 16. We do not knowingly collect personal data from children. If you believe we have collected data from a child, please contact us and we will delete it promptly.

11. International Data Transfers

Your data may be transferred to and processed in countries other than your own. We ensure appropriate safeguards are in place, including standard contractual clauses approved by relevant authorities.

12. Changes to This Policy

We may update this privacy policy from time to time. We will notify you of material changes by posting the updated policy on our website and updating the "Last updated" date. Your continued use of our service after any changes constitutes acceptance of the updated policy.
