Privacy Policy

1. Data We Collect

We collect minimal data, limited to what is necessary to deliver and support the product:

• Purchase information: When you buy Murmur, your name, email address, and payment details are processed by our merchant of record, Polar Software, Inc. (or Gumroad for legacy purchases). We receive your email and license key to deliver and validate your purchase.
• License validation: When Murmur checks your license, it sends your license key and a minimal device identifier to verify activation. No text, audio, or usage data is transmitted.
• Website analytics: Our website may collect anonymous, aggregated analytics such as page views, referrers, country-level location, checkout clicks, download clicks, and audio sample plays using privacy-respecting tools. No personal identifiers are stored in website analytics.
• App diagnostics and product telemetry: Murmur may send privacy-preserving diagnostics and usage events, such as app launches, feature success or failure, selected model or voice identifiers, text length, generation timing, import counts, export format, and crash reports. These events help us improve reliability and understand which features are working.

2. Data We Do Not Collect

Murmur processes all text-to-speech locally on your Mac. We never collect:

• Text you type or generate speech from
• Audio files you create
• The full text of your prompts or documents
• Files on your device
• Microphone or camera data

3. How We Use Your Data

• To deliver your license key and validate your purchase
• To provide customer support when you contact us
• To send transactional emails related to your purchase (receipts, license delivery)
• To improve our website and marketing (anonymized analytics only)
• To improve app reliability and feature quality using diagnostics and aggregate product telemetry

4. Third-Party Services

We use the following third-party services:

• Polar Software, Inc. (merchant of record): Processes payments, handles billing, and manages transaction records. Their privacy policy applies to payment processing.
• Gumroad (legacy merchant of record): Processes payments for customers who purchased through our Gumroad listing. Their privacy policy applies to those transactions.
• Vercel Web Analytics: Measures website page views and aggregate traffic patterns.
• PostHog: Measures website page views and aggregate conversion events such as checkout clicks, download clicks, and audio sample plays. Session recording is disabled for Murmur's website.
• TelemetryDeck: Processes privacy-preserving app telemetry events so we can understand app usage and reliability.
• Sentry: Processes crash reports and non-fatal errors so we can diagnose and fix app problems.

We do not sell, rent, or share your personal information with any other third parties for marketing purposes.

5. Data Storage and Security

Purchase records and license data are stored securely with industry-standard encryption. Since Murmur runs locally, your content (text and audio) never leaves your Mac and is stored only on your device.

6. Data Retention

We retain your email and license information for as long as your license is active, plus any period required by applicable tax and financial regulations. You may request deletion of your data at any time by contacting us.

7. Your Rights

Depending on your jurisdiction (GDPR, CCPA, etc.), you may have the right to:

• Access the personal data we hold about you
• Request correction of inaccurate data
• Request deletion of your data
• Restrict or object to processing of your data
• Request data portability

To exercise any of these rights, email us at tarunyadav9761@gmail.com. We will respond within 30 days.

8. Children's Privacy

Murmur is not directed at children under 13. We do not knowingly collect personal information from children. If you believe a child has provided us with personal data, please contact us and we will delete it promptly.

9. Changes to This Policy

We may update this privacy policy from time to time. Changes will be posted on this page with an updated date. Continued use of Murmur after changes constitutes acceptance of the revised policy.
